The results of this study suggest that an onlay osseous graft protected by a Ti-Mesh demonstrated significantly less bone resorption when compared with an onlay bone graft alone. This benefit was reduced in case of short-term mesh exposure, with limited drawbacks.

The aim of this study is to evaluate a surgical protocol for vertical ridge augmentation in the maxilla and mandible using autogenous onlay bone graft associated with a titanium mesh. A group of 18 partially edentulous patients, presenting the need for vertical bone augmentation of at least 4 mm, were treated before implant placement. During the first surgery, an autogenous bone graft was harvested from either the mandibular ramus or the mental symphysis and secured by means of titanium screws. Particulate bone was added and a titanium micro-mesh was used to stabilize and protect the graft. After a mean interval of 4.6 months, meshes and screws were removed and 37 endosseous implants were successfully placed. The desired bone gain was reached in all patients. Mean vertical bone augmentation obtained was 4.8 mm (range 4-7 mm). No major complications were recorded at recipient or donor sites. Abutment connection was carried out 2-3 months after implant placement. No implant was lost. Clinical parameters and probing depth, after prosthetic reconstruction, demonstrated the presence of a healthy peri-implant mucosa. The preliminary results suggest that, by using the presented technique, patients can be successfully rehabilitated by means of implant-supported prosthesis 6-7 months after the first surgery, even in case of severely atrophied maxilla.

Purpose: The purpose of this retrospective study was to analyze the epidemiology, patterns, and management of maxillofacial due to road traffic accidents over a 17-year period. Methods: Between January 2001 and December 2017, 2924 patients with maxillofacial fractures were admitted to the Division of Maxillofacial Surgery, Turin, Italy. The following data were analyzed: age, gender, data of the trauma, alcohol and drug abuse, mechanism of injury, fracture site, facial injury severity scale, associated injuries, type of treatment, and length of hospital stay. Results: Of the 605 patients included in the study, 419 were male and 186 were female (ratio, 2.2:1). The most common mechanism of injury was car accidents (62.6%). More than half of the patients had fractures of the middle third of the maxillofacial skeleton. Associated injuries were detected in 172 (45.5%) patients. In total 5.3% of patients did not undergo surgery. The average hospital stay was 7.3 days. Conclusions: This study shows an important reduction in maxillofacial fractures following road traffic accidents since the turn of the new millennium. At least in north-western Italy, road safety policies implemented in the last 30 years seem to have affected the behavior of motorists and motorcyclists.
