Background: Presurgical nasoalveolar molding (NAM) improves outcomes in infants with cleft lip and palate by guiding alveolar segment alignment and enhancing nasal symmetry prior to primary lip repair. However, traditional NAM protocols require frequent clinical visits and specialized expertise, limiting access for families in rural and low-resource settings. Objective: This retrospective clinical study evaluated the feasibility and clinical outcomes of a digitally guided NAM approach using thermoformed clear aligners in infants with unilateral complete cleft lip and palate. Material and Methods: Twenty-five neonates residing in rural regions were treated over a 20-week pre-surgical period using a digital workflow that included intraoral scanning, 3D model design, and sequential aligner fabrication. The protocol minimized the number of in-office visits while engaging caregivers in home-based appliance management. Anatomical changes were assessed using 3D models at baseline and at treatment completion. Results: Significant reductions were observed in anterior cleft width (mean decrease: 5.38 mm, 95% CI: –7.58 to –3.18, p < 0.001) and posterior cleft width (mean decrease: 3.39 mm, 95% CI: –4.79 to –1.99, p < 0.001). Intermolar distance increased by 1.23 mm (p = 0.036), while intercanine width remained stable (p = 0.515), indicating preservation of maxillary arch form. Surgeons reported improved nasal symmetry and tissue alignment at the time of lip repair. Conclusions: This digitally planned NAM clear aligner protocol demonstrated clinical feasibility and effectiveness in reducing cleft width during the pre-surgical period. Findings should be interpreted with caution, given the retrospective design, lack of a control group, and absence of objective nasal outcome measures. Further studies are recommended to assess long-term outcomes and broader implementation potential. Full article

Background/Objectives: During alveolar cleft grafting, the use of autogenous cancellous bone harvested from the iliac crest is still considered the gold standard. Due to the risk of donor-site morbidity and excessive graft resorption, alternative grafting materials (e.g., intraoral bone, xenografts) are being tested. The aim of this study was to compare the efficacy of using an autologous tooth-derived graft material and iliac crest cancellous bone in the reconstruction of the alveolar cleft in patients with a unilateral cleft lip and palate. Methods: A total of 21 patients with a unilateral cleft lip and palate, who underwent alveolar bone grafting between 2020 and 2023 were included in the study. In 11 cases, the donor site was the iliac crest; in the rest of the cases, deciduous teeth were harvested, processed, and used as an autologous particulate graft material for alveolar reconstruction. The mean follow-up time was 30.0 months, CBCT scans were taken, and the results were compared based on the ranking system published by Stasiak et al. Results: The Wilcoxon signed-rank test showed that the amount of bone on the cleft side was significantly less than that on the contralateral non-cleft side (ATB: p = 0.002, iliac crest: p = 0.005). The Mann–Whitney U test showed that there were no significant differences in bone quantity on the cleft side between the two groups (U = 47.5, p = 0.617). Conclusions: The use of ATB might be a feasible alternative to autologous bone during alveolar cleft reconstruction. This type of graft shows long-term stability, which is comparable to the bone harvested from the iliac crest. Full article

Background: This study investigated the effects of preoperative maxillary plates on cleft width reduction in infants with unilateral cleft lip and palate and their control group. The study also aimed to compare the digital and manual methods in measurement of changes in maxillary segment positioning in sagittal and transverse dimensions using digital 3D models and conventional plaster casts. Methods: Twenty infants with unilateral cleft lip and palate and their control group of eleven infants with isolated cleft palate were enrolled in a prospective interventional study (2020 to 2024). Participants were treated with either active or passive maxillary plates. Sagittal, transversal and angular measurements were taken both manually as well as digitally at three time points: 24–48 h postnatal (T0), approximately at six months old (T1, immediately before surgery), and one year postoperatively (T2). Results: Significant reductions in cleft width were observed across all patients over the treatment period, regardless of the type of plate used (p < 0.001). The mean cleft width reduction was 5.050 mm. Infants treated with active plates had a larger reduction in cleft width than those with passive plates (p = 0.024), averaging 5.846 mm compared to 3.571 mm. Neither the side of the cleft nor the patient’s gender influenced the degree of cleft reduction (p = 0.884 and p = 0.245, respectively). The study found significant modifications in the maxilla’s transverse, sagittal, and angular dimensions (p < 0.001). When comparing sagittal growth, the study group differed from the control group (p = 0.004), with isolated cleft palate patients showing more substantial sagittal expansion. Additionally, the overall change in the ITT’ distance differed significantly between the study and control groups over time (p < 0.001). Cleft size at baseline did not affect the extent of changes within the cleft area. No significant discrepancies were found between digital and manual measurement methods, confirming the reliability of both. Conclusions: Active plates demonstrated greater efficacy in cleft reduction for wider and more divergent clefts, while passive plates were suitable for smaller clefts. Full article

Background/Objectives: This study evaluated the effects of vascular photobiomodulation (VPBM) on pain intensity, edema, and facial temperature variation in patients undergoing alveolar bone grafting (ABG) surgery. Methods: A total of 42 patients with cleft lip and palate (aged 9–25 years) scheduled for ABG using iliac crest bone were randomly assigned in equal numbers (14 per group) to one of three groups: control (ABG only), test (ABG + VPBM), and placebo (ABG + simulated VPBM). Iliac and facial pain and edema were clinically evaluated 24 h post-surgery, along with thermographic facial analysis. Follow-up was conducted via phone calls for one week. Results: No statistically significant differences were observed among the groups regarding facial pain and edema at 24 h post-surgery. However, iliac pain significantly differed between the placebo and control groups (p = 0.045). A significant time-related effect on both facial and iliac pain outcomes was noted during follow-up, irrespective of the group. The need for rescue medication and self-perception of reduced edema did not differ significantly. Thermographic analysis reveals a significantly lower temperature variation in the test group (2.36 °C) compared to the other groups (p = 0.007). Conclusions: Overall, VPBM therapy influenced postoperative pain in the early recovery phase and temperature in the immediate postoperative period but did not significantly affect edema.

Anterior lip/palate cleft is a congenital deformity affecting the upper lip and palate, posing significant challenges in both aesthetic and functional aspects for children. Effective management of this condition is crucial for improving quality of life and ensuring normal development. This review aims to highlight the regenerative treatment options available for children with anterior lip/palate cleft, focusing on the use of bone grafts and other advanced dental procedures. A review of the current literature and clinical practices was conducted to identify and evaluate the most effective treatment options. Emphasis was placed on regenerative techniques, particularly the use of bone grafts. Advancements in regenerative dentistry offer promising outcomes for children with anterior lip/palate cleft. Bone grafts, combined with innovative techniques such as growth factors, stem cell therapy, and distraction osteogenesis, provide effective solutions for restoring function and aesthetics. A multidisciplinary approach is essential to ensure comprehensive care and optimal results for these patients. Full article

Background: Alveolar bone reconstruction with recombinant protein has several advantages, including less surgical timing, and reduced infection. This systematic review aims to assess the efficacy of recombinant human bone morphogenetic protein-2 (rhBMP-2) as a treatment modality for children with cleft lip and palate compared to the conventional iliac crest bone grafting approach. Methods: For current systematic review and meta-analysis, five electronic databases, namely, MEDLINE/PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, Web of Science, and ScienceDirect, were searched. The primary outcome measured in this review was bone volume and height after alveolar bone reconstruction surgery. The Risk of Bias Tool 2 assessed the risk of bias for randomized control trials and the Risk of Bias tool for non-randomized trials of interventions for non-randomized studies. By evaluating pooled meta-analysis, the mean difference was calculated. GRADE uncertainty of evidence was performed to assess the certainty of the results. Results: Of 230 identified studies, 6 randomized and 2 non-randomized studies were included in the current review. The average bone volume was higher among the rhBMP-2 group at 61.11% ± 24.6% than the iliac crest group at 59.12% ± 18.59%. The calculated mean bone height was higher in the iliac crest group at 78.65% ± 14.38% than in the rhBMP-2 group at 67.5% ± 5.45%. The risk of bias reported in the studies was low to moderate. The result of the meta-analysis supported using rhBMP-2 in alveolar bone reconstruction; however, no significant association was found (mean difference: −1.24; confidence interval: −4.14 to 1.67). Conclusions: The calculated meta-analysis reported no significant difference, and the quality of evidence measured was also moderate. Hence, more clinical trials are required to support using rhBMP-2 as an alternative to traditional techniques for treating cleft lip and palate. Full article

Background: This systematic review and meta-analysis aimed to investigate the effects of presurgical orthopedics (PSO) on maxillary arch dimensions in infants with cleft lip and palate during the first year of life. Methods: The review was conducted following PRISMA guidelines. A comprehensive electronic search was performed in MEDLINE, Embase, Cochrane, Scopus, and Google Scholar databases, supplemented by manual searching. Two reviewers independently conducted study selection, data extraction, quality assessment, and risk of bias evaluation. Results: Five studies were included in the meta-analysis. Quantitative analysis was performed based on the primary outcomes. The estimate was calculated using a random-effects model and z distribution (95% confidence interval (CI)). The results showed similar alveolar cleft widths (mean difference, −3.06; 95% CI, −8.03 to 2.70, p = 0.30, I2 = 99%) with clinical differences in favor of PSO, and comparable posterior cleft widths (mean difference, −0.88; 95% CI, −2.06 to 0.30, p = 0.14, I2 = 89%) with and without PSO in CLP babies. Conclusions: This meta-analysis found no statistically significant effects of presurgical orthopedic treatment on maxillary arch dimensions in infants with cleft lip and palate during the first year of life. Further high-quality randomized controlled trials are needed to definitively establish the efficacy of PSO. Full article

Background/Objectives: Digital impressions are increasingly used to manage Cleft lip and/or palate (CL/P), potentially offering advantages over traditional methods. This laboratory investigation sought to evaluate the impact of scanning tip sizes, different scanners, and scanning strategies on intraoral scanning in neonates with CL/P. Methods: Ten soft acrylic models were used to simulate the oral anatomy of neonates with CL/P, evaluating parameters such as the ability of different scanning tips to capture alveolar cleft depth, scanning time, number of scan stops, and scan quality. The study utilised various scanning tips, including the Carestream normal tip, Carestream side tip, and Trios 4 scanner tip to assess the alveolar cleft depth measurements. The Trios 4, Carestream, and iTero scanners were evaluated for the time taken, number of scan stops during cleft-unobstructed scanning and cleft-obstructed scanning. The quality of all scanned images was analysed. Results: The findings showed comparable accuracy in capturing alveolar cleft depth with the three-scanning tip (p > 0.05). Scanning time and the number of scan stops did not significantly differ across the three scanners and various scanning strategies employed (p > 0.05). However, scanning with the cleft obstructed required less time and resulted in fewer scan stops compared to cleft -unobstructed scanning. Despite these results, all scanners failed to record the deepest part of the alveolar cleft, highlighting a limitation in current scanning technology for neonates with CL/P. Conclusions: The study recommends enhancing intraoral scanning in this population by adjusting tip size, improving clinician training, optimizing protocols, and conducting further research to improve techniques.

Background/Objectives: Defects in maxillary and mandibular alveolar ridges are common in maxillofacial practice. Reconstruction with microvascular bone grafts and subsequent prosthetic rehabilitation is the gold standard treatment. This study investigated patients’ quality of life (QoL) after microvascular alveolar ridge reconstruction with subsequent dental rehabilitation. The effect of the underlying disease and success rates of the prosthetic treatment on QoL were analysed. Methods: OHIP-49 was used to evaluate oral health-related QoL (OHrQoL). The SF-36 was used to assess disease-nonspecific QoL. Results: Fifty-eight patients were enrolled and divided into four diagnostic (malignancy, osteoradionecrosis, benign disease, and cleft palate) and five prosthetic groups (no prosthetics, removable partial dentures, complete dentures, implant-supported removable dentures, and implant-supported fixed dentures). There was a significant difference between the diagnostic groups in the total score of their OHIP-49 (p = 0.008). Patients with malignant disease and osteoradionecrosis had worse QoL scores than those with benign diseases and cleft palate. Implant-supported prostheses had the best OHrQoL. Removable partial dentures and patients in whom dental rehabilitation was not possible had the worst OHrQoL (p = 0.042). The SF-36 subscale score showed no statistically significant differences between the diagnostic and prosthetic groups (p > 0.05). Conclusions: OHrQoL after microvascular alveolar ridge reconstruction differs significantly based on underlying diagnoses and prosthetic restorations. Benign diseases and implant-supported dentures have the highest scores. Full article

Background and Objectives: Cleft lip alone or a combination of cleft lip and palate (CLP) is a common developmental abnormality in the craniofacial region. This umbrella review aims to identify promising avenues for treatment using stem cell therapy. Materials and Methods: Systematic reviews from 2014 to 2024 were searched among databases like PubMed, Medline, and Google Scholar. PRISMA guidelines were employed to ensure the thoroughness of the search. A quality assessment (ROBIS) of the included reviews was conducted to ensure the reliability and validity of the synthesized evidence. Results: Five systematic reviews were selected for this umbrella review. Results show that stem cell therapy, specifically using mesenchymal stem cells (MSCs) and adipocyte stem cells (ADSCs), promotes bone regeneration in CLP deformities. Although multiple studies have established the effectiveness of diverse types of stem cells in treating CLP, important considerations including safety concerns, methodological variability, and the need for standardization have been identified. The fact that the number of relevant systematic reviews that matched our inclusion criteria was limited could affect this research’s robustness and may limit the breadth and depth of evidence synthesis. Definitive conclusions could not be reached due to variation among treatments and outcomes. Conclusions: The examined studies highlight the potential of stem cell therapy as a complementary approach to existing treatments for CLP. However, there are challenges that need to be addressed, including concerns regarding safety, variations in methodologies, and the need for standardization. Exploring the potential of other stem cell types may further enhance treatment outcomes for CLP patients. Full article

Background: This study reviews the surgical and functional outcomes of children diagnosed with a bilateral cleft lip and palate and treated by the same surgical team following specific surgical protocols 18 years after surgery and during the follow-up. Methods: Based on a single-center retrospective design, demographic and surgical data were gathered by the authors from international institutions. Most of the data were quantitative in nature, and descriptive statistical and non-parametric tests were employed for analysis. All children born with a bilateral cleft from 1982 to 2002 were considered. Children affected by a syndrome were excluded. Complications and speech results were the main items measured. Results: Thirty patients were selected; 73.3% were treated using the inverse Malek procedure, and 26.7% underwent a modified two-stage procedure. Seventy percent developed an oronasal fistula. An alveolar bone graft was performed in 83%, and 53.3% underwent Le Fort osteotomy. Thirty-six percent required a pharyngeal flap, with good speech results. The median number of times general anesthesia was used among all the interventions considered was 5.5 (4.25–6). Conclusions: This study presents the long-term results of using the inverse Malek procedure to treat children with a bilateral cleft lip and palate. It is shown that this is related to a high risk of developing a fistula, but has good long-term speech results. Full article

(1) Background: Cleft lip, alveolus, and palate are the most common congenital abnormalities in the world, occurring in one in seven hundred live births. Secondary alveolar bone grafting (SABG) is usually performed when the permanent canine root shows one-half to two-thirds of root development. To improve the surgical outcome, supplemental grafting materials such as platelet-rich fibrin (PRF) and platelet-rich plasma (PRP) have been used as an adjunct. This review is designed to assess the efficacy of PRF and PRP in improving the outcome of SABG. (2) Methods: A comprehensive literature search was performed until 13 October 2022 on MEDLINE, EMBASE, The Cochrane Library, and Pubmed. The full text of potentially relevant studies was reviewed, and only randomised clinical trials (RCTs) were included based on the inclusion criteria. (3) Results: A total of 656 studies were screened, of which four were included for final review. All of the four included studies that evaluated the quantitative or qualitative surgical outcome in varied ways. (4) Conclusions: Results of this review suggest that both PRF or PRP and control group (without the use of PRF/PRP) achieved similar successful outcomes in bone height, bone density, and bone volume in both qualitative and quantitative assessment.

Cleft lip and palate (CLP) is the most common craniofacial malformation, with a range of physical, psychological, and aesthetic consequences. In this comprehensive review, our main objective is to thoroughly examine the relationship between CLP anomalies and the use of artificial intelligence (AI) in children. Additionally, we aim to explore how the integration of AI technology can bring about significant advancements in the fields of diagnosis, treatment methods, and predictive outcomes. By analyzing the existing evidence, we will highlight state-of-the-art algorithms and predictive AI models that play a crucial role in achieving precise diagnosis, susceptibility assessment, and treatment planning for children with CLP anomalies. Our focus will specifically be on the efficacy of alveolar bone graft and orthodontic interventions. The findings of this review showed that deep learning (DL) models revolutionize the diagnostic process, predict susceptibility to CLP, and enhance alveolar bone grafts and orthodontic treatment. DL models surpass human capabilities in terms of precision, and AI algorithms applied to large datasets can uncover the intricate genetic and environmental factors contributing to CLP. Additionally, Machine learning aids in preoperative planning for alveolar bone grafts and provides personalized treatment plans in orthodontic treatment. In conclusion, these advancements inspire optimism for a future where AI seamlessly integrates with CLP management, augmenting its analytical capabilities. Full article

Autologous bone grafting is the primary method for treating alveolar clefts. However, bone grafting materials are desired as alternatives to autogenous bone to reduce surgical invasiveness. Here, we present an animal study evaluating the effect of carbonate apatite (CA) on the spontaneous eruption of permanent teeth. The bone grafting materials included CA, natural bovine bone (BB), and hydroxyapatite (HA). In 15 8-week-old male beagle dogs, the left mandibular deciduous premolars (DP) two and three were extracted and subsequently filled with CA, BB, and HA. The animals were euthanized after a predetermined number of days, and samples were collected for microcomputed tomography and histological evaluation. Spontaneous eruption of the succeeding permanent teeth (P3 and P4) was observed in the CA group at 14 weeks. Delayed eruption of the succeeding permanent teeth was observed in the BB and HA groups. CA could serve as a viable alternative to autogenous bone for treating alveolar clefts. Full article

Alveolar bone grafting (ABG) is a critical surgical intervention in patients with a cleft of the alveolus, aimed at reconstructing the alveolar ridge to facilitate proper eruption, periodontal support, and alignment of adjacent permanent teeth. The optimal timing for ABG remains debated, with late secondary ABG between the ages of 9 and 11 being widely adopted. This study compared the palatal shapes of 28 children at a mean age of 9.5 years (SD = 0.7) who underwent early secondary ABG at a mean age of 2.1 years (SD = 0.6) or 33 children at a mean age of 10.8 years (SD = 1.5) who underwent late secondary ABG at a mean age of 8.6 years (SD = 1.3) to 60 non-cleft controls at a mean age of 8.6 years (SD = 1.2). The palatal shapes were captured with 239 landmarks digitized on the palate on a digital model. Utilizing geometric morphometric methods, i.e., generalized Procrustes superimpositions, principal component analysis, and permutation tests, we assessed the impact of ABG timing on palatal morphology. The first five principal components (PCs) explained 64.1% of the total shape variability: PC1 = 26.1%; PC2 = 12%; PC3 = 11.9%; PC4 = 7.8%; and PC5 = 6.4%. The Procrustes distance between both cleft groups and the control group was more than twice as large as the Procrustes distance between the early ABG and late ABG groups. Nonetheless, all intergroup differences were statistically significant. Our findings suggest that early ABG has a limited negative effect on palatal shape, providing comparable outcomes to late ABG. The study highlights the potential suitability of early ABG, challenging conventional practices and encouraging further exploration into its long-term effects on maxillary growth. Full article
