Topic Information

Dear Colleagues,

Oral and maxillofacial surgery is dedicated to the surgical treatment of pathological conditions that affect the mouth, jaw and face. The oro-facial and maxillofacial deformities constitute a large group of anomalies that have in common the existence of alterations in the shape, position and size of the distinct musculoskeletal elements of the face. These deformities can be congenital, appear and worsen during development, or be secondary to trauma, cancer or tooth loss. In many cases, the alterations of the facial skeleton: upper jaw and mandible can cause alterations of the dental occlusion, so it is often the dentist or orthodontist who identifies the pathology first and should refer it to the maxillofacial surgeon.

Compared to traditional methods, the ultimate goal of modern digital technologies is to improve the quality and possibilities of intervention in carrying out patient assessment, diagnosis and treatment. Today in dentistry, there is a real digital revolution.

Thanks to digital technology, important results can be offered to patients who can pass from extraction to a functional and aesthetic temporary prosthesis that is similar to the final result within a day. In the near future, new materials, such as high-strength polymers, are on the way.

Abstract

Background: Extracted tooth material has been seen as a valuable alternative to synthetic biomaterials. Aims: A novel flapless alveolar socket preservation (ASP) procedure with demineralized extracted tooth dentin graft material covered by three reabsorbable membranes was histologically and clinically evaluated 4 months after bone healing. Methods: Ten patients were enrolled and separated into two groups. Five post-extractive sites without buccal and/or palatal bone walls were treated with the flapless ASP procedure with demineralized tooth dentin covered with three reabsorbable membranes (Group A—GA). Five patients were treated with primary wound closure covered only with a reabsorbable membrane (Group B—GB). Bone biopsies were performed for histologic and histomorphometric analyses. Results: In both procedures, all clinical outcomes showed good healing of hard and soft tissue and a good maintenance of maxillary architecture. The histological analysis showed no necrosis or inflammatory areas in either group. The histomorphometric analysis showed higher total bone volume in GA (62.78 ± 7.97%) compared to GB (48.04 ± 9.32%), higher vital new bone in GA (57.53 ± 11.16%) compared to GB (42.41 ± 13.06%) and similar values for residual graft in GA (5.24 ± 5.82%) compared to GB (5.29 ± 4.83%). Conclusions: The data obtained show how this novel technique, mixed with the dentin-derived graft material, seems to promote higher bone regeneration. Full article

Abstract

The aim of this study is to identify a method that can maximize implant primary stability (IPS) and bone density under the controlled drilling conditions of the same diameter and length in low-density bones through an ex vivo study. A total of 87 dental implants were placed with standard drilling, under-drilling, and osseodensification drilling in 13 fresh porcine sternums. The Periotest value and the implant stability quotient were measured to evaluate the primary stability. The difference in the Hounsfield unit (HU) between the hole and peripheral bone up to a distance of 1 mm was measured. Osseodensification and under-drilling technique increased the IPS, compared with conventional drilling technique with statistical significance under the drilling conditions of the same diameter and length. Osseodensification technique with the counter-clockwise direction had higher HU gaps than the standard drilling and osseodensification technique with clockwise direction. Due to the effect of bone densification, the gap of HU was increased by a minimum of 43 HU and a maximum of 180 HU. Within the limitations of this ex vivo study, it was found that the osseodensification technique with counter-clockwise direction is effective to increase IPS and bone mineral density in low-density bone.

Abstract

Aims: The aim of this review is to consider maxillary sinusitis as a complication of zygomatic implants placements. Maxillary sinusitis a common complication but in the literature there are no reviews that focus only on this condition and its possible treatment. This review was carried out with to highlight the main findings of the literature on this topic and to improve knowledge in this field. Methods: The search strategy resulted in 155 papers. After selection of the inclusion criteria only 11 papers were examined. From the papers these, 12.3% patients presented maxillary sinusitis but only four studies evaluated sinusitis (both clinical and radiological evaluation). The most common treatment used by the authors were antibiotics alone or combined with functional endoscopic sinus surgery (FESS). Results: The literature shows an absence of precise and shared guidelines diagnosis and post-operative follow-up, and of the treatment of maxillary sinusitis following zygomatic implantology. It has not been determined if the surgical placement of ZIs is better than the other techniques for treatment of the onset of maxillary sinusitis in the post-operative period. Conclusion: To date there are no shared protocols for maxillary sinusitis treatment. In our experience, and according to the literature in the presence of risk factors such as age, comorbidities, smoking, nasal septal deviation or other anatomical variants, we suggested that FESS is performed at the same time as placement of zygomatic implants.

Abstract

The recently adopted Medical Device Regulation (MDR) has finally entered into force on 26 May 2021. As innovation and especially the advent of customized prostheses has deeply modified many surgical procedures in our discipline, it is imperative for the contemporary surgeon to become aware of the impact that the MDR will have on many aspects, including the choice of the manufacturer, the evaluation of the devices, point-of-care 3D printing labs, and medical software. In this paper, the authors tried to identify the cultural gaps in clinical practice that the MDR is supposed to fill. To achieve this purpose, a task force of experts was reunited, including CMF surgeons with direct expertise in medical software and 3D printing, mechanical and material engineers, facing the topic of the MDR from a multidimensional perspective. In this article, surgeons and engineers review many crucial aspects concerning the points of the regulation that mostly affect the field of implantable devices for the cranio-maxillo-facial skeleton. The result of interdisciplinary research is a paper aiming to provide surgeons with the knowledge on the fundamental processes of additive manufacturing, increasing the clinician’s awareness on the evaluation of a customized implant before surgery and on the underlying regulatory framework.

Abstract

Background: To study the safety and efficacy provided by a minimal and localized anesthesia in cataract surgery. Methods: Randomized controlled trial. A total of 100 patients undergoing cataract surgery were randomly divided into two groups of 50, which respecitvely received conventional topical anesthesia consisting of preservative-free Oxibuprocaine hydrochloride 0.4% drops or minimal localized anesthesia, administered with a cotton bud soaked in preservative-free Oxibuprocaine hydrochloride 0.4% applied to clear cornea on the access sites for 10 s immediately before surgery. The mean outcome measures were intraoperative pain and the incidence of postoperative ocular discomfort. Results: All patients tolerated well the procedure, giving patin scores between 1–3. Fifteen patients (30%) of group 1 and ten of group 2 (25%) required supplemental anesthesia. No intraoperative complications were recorded. No eyes had epithelial defects at the end of the surgery or at postoperative check-ups. Conclusions: Minimal anesthesia in cataract surgery resulted quick, safe and non-invasive. Full article

Abstract

The aim of this study is to demonstrate the use and the effectiveness of cephalometry and golden proportions analysis of the face in planning prosthetic treatments in totally edentulous patients. In order to apply this method, latero-lateral and posterior-anterior X-rays must be performed in addition to the common procedure. Two main concerns for totally edentulous patients are the establishment of the vertical dimension and the new position of the occlusal plane. The divine proportion analysis was carried out by the use of a golden divider. The prosthetic protocol was divided into three steps and a case was selected for better understanding. Referring to the golden relations, if the distance from the chin to the wing of the nose is 1.0, the distance from the nose to eye is 0.618. This proportion is useful and effective in determining the correct prosthetic vertical dimension. The incisal margin of the lower incisor must be positioned between Point A (A) and protuberance menti (Pm) according to the gold ratio 0.618 of the total height A-Pm. Posteriorly the occlusal plane must be placed 2 mm below the divine occlusal plane (traced from the incisal margin of lower incisors to Xi point). A prosthesis made in accordance with cephalometric parameters and divine proportions of the face helps to improve the patient’s aesthetics, function and social personality. Full article
