Background/Objectives: In the last decades, dental implant surfaces have been evolving to increase success and implant survival rates. More studies evaluating outcomes with implants with ultra-hydrophilic multi-zone anodized surfaces are necessary. The aim of this study is to evaluate the short-term outcome of implants of conical connection with anodized ultra-hydrophilic surfaces for support of single teeth and partial rehabilitations. Methods: In this retrospective study, patients received parallel-walled implants with a gradually anodized surface. The primary outcome measure was implant survival. Secondary outcome measures were marginal bone loss and mechanical and biological complications. This study included 253 conical connection implants with anodized ultra-hydrophilic surfaces, placed in 145 patients (71 males and 74 females; average age: 55.8 years). Sixty patients presented comorbidities, and 19 patients presented smoking habits. Results: Ten patients (15 implants) were lost to follow-up. Two implants failed in two patients, resulting in a cumulative survival rate of 99.2%, with 98.5% and 100% for males and females, respectively, and 99.1% and 100% for single teeth and partial rehabilitations, respectively. The average marginal bone loss was 0.52 mm at 1 year, with 0.60 mm and 0.42 mm for males and females, respectively, and 0.52 mm and 0.50 mm for single teeth and partial rehabilitations, respectively. The rate of mechanical complications was 4.8% and 3.2% at patient and implant levels, respectively. Biological complications occurred in one patient (0.7%) at one implant (0.4%). Conclusions: These results indicate that the use of implants with ultra-hydrophilic multi-zone anodized surfaces for single teeth and partial rehabilitations is viable in the short term. Full article

Background: Mini dental implants (MDIs) are alternatives to support an overdenture when a standard diameter implant cannot be placed due to lack of bone volume. They reduce the need for invasive bone grafting and lower the barrier for treatment. Aim: This prospective study reports on implant and patient-centered outcomes of flaplessly placed, early loaded MDIs supporting horseshoe-shaped maxillary overdentures after 7 years of function. Materials and Methods: Patients with a CBCT-confirmed thin alveolar crest received 5–6 one-piece MDIs using mentally guided flapless surgery. The conventional denture was relined and MDIs were provisionally loaded within one week. After 6 months the non-splinted MDIs were actively loaded with a horseshoe overdenture. Implant and prosthetic survival, peri-implant health (PPD and BoP) and patient-related outcomes using OHIP-14 and Subjective Masticatory Evaluation were assessed after 7 years. Results: 185 MDIs were placed in 14 females and 17 males. During provisional loading, 32 MDIs were lost, and 17 replacements were required in 16 patients. In total, 170 out of 202 totally placed MDIs were supporting 29 overdentures after 6 months. Cumulative implant failure increased from 15.8% at the moment of active loading to 34.7% at 7 years. After 7 years, 76% of the initially placed overdentures remained functional, mean PPD was 3.48 (SD 0.86), BoP was 0.20 (SD 0.40) and peri-implantitis incidence was 0.9%. The total OHIP-14 was reduced from 21.3/56 (SD: 13.1) preoperatively to 15.6/56 (SD 12.8) at provisional loading (p > 0.1) and 7.3/56 (SD 6.7) at final loading (p = 0.006), and it remained unchanged up to 7 years at 6.57/56 (SD: 8.92) (p > 0.5). Conclusions: Maxillary MDIs provide an acceptable treatment option in patients with deficient bone volume that cannot or refuse to be treated with bone grafting. Despite one third of the MDIs being lost, remaining MDIs had good peri-implant health, prosthetic success was 71% and Oral Health Related Quality of Life was beyond expectations. Full article

Background: Recent advancements in dental implantology have significantly improved outcomes, with success rates of 90–95% over a 10-year period. Key improvements include enhanced preplanning processes, such as precise implant positioning, model selection, and optimal insertion depth. However, challenges remain, particularly in achieving correct spatial positioning and alignment of implants for optimal occlusion. These challenges are pronounced in patients with reduced bone substance or complex anthropometric features, where even minor misalignments can result in complications or defects. Methods: This paper introduces a vision-guided robotic system designed to improve spatial positioning accuracy during dental implant surgery. The system incorporates advanced force-feedback control to regulate the pressure applied to bone, minimizing the risk of bone damage. A preoperative CBCT scan, combined with real-time images from a robot-mounted camera, guides implant positioning. A personalized marker holder guide, developed from the initial CBCT scan, is used for patient–robot calibration. The robot-mounted camera provides continuous visual feedback of the oral cavity during surgery, enabling precise registration of the patient with the robotic system. Results: Initial experiments were conducted on a 3D-printed mandible using a personalized marker holder. Following successful patient–robot registration, the robotic system autonomously performed implant drilling. To evaluate the accuracy of the robotic-assisted procedure, further tests were conducted on 40 identical molds, followed by measurements of implant positioning. The results demonstrated improved positioning accuracy compared to the manual procedure. Conclusions: The vision-guided robotic system significantly enhances the spatial accuracy of dental implants compared to traditional manual methods. By integrating advanced force-feedback control and real-time visual guidance, the system addresses key challenges in implant positioning, particularly for patients with complex anatomical structures. These findings suggest that robotic-assisted implant surgery could offer a safer and more precise alternative to manual procedures, reducing the risk of implant misalignment and associated complications.

Background: Achieving ideal anchorage is crucial in orthodontics for controlled tooth movement. Miniscrews (MSs) have improved skeletal anchorage, but freehand placement poses risks like root damage and limited precision. Guided techniques, including radiographic guides and computer-assisted methods (static [sCAS] and dynamic [dCAS]), were developed to enhance accuracy and safety. Objective: This systematic review and meta-analysis aimed to evaluate the safety and accuracy of MS placement using different guidance approaches. Materials: A systematic search up to March 2024 identified studies on guided MS insertion, assessing safety (root contact/damage) and accuracy (angular, coronal, and apical deviations) of guided vs. freehand placement. Two reviewers assessed the risk of bias and study quality using RoB 2 for RCTs, NOS for cohort studies, and an adapted tool for pre-clinical studies. Random-effects meta-analysis was performed for studies with common parameters, and safety outcomes were pooled using logit-transformed proportions. Heterogeneity was evaluated with I² and χ² tests. Results: Eleven studies (652 MSs) were included, though no dCAS studies were analyzed. The only RCT had “some concerns” regarding risk of bias, cohort studies ranged from medium to low quality, and most pre-clinical studies had high bias risk. sCAS significantly reduced root damage compared to freehand methods (OR = 0.11; 95% CI: 0.04–0.36; p < 0.001; I² = 1%) and reduced angular and linear deviations. Due to heterogeneity, no quantitative synthesis of accuracy outcomes was performed. Conclusions: sCAS improves the safety and accuracy of MS insertion compared to freehand and radiographic guide methods. These results highlight the clinical benefits of sCAS in orthodontics. Future studies should refine protocols and explore dCAS for further accuracy improvements. Full article
