Fractures of the mandibular angle account for 23 to 42% of all facial fractures with a high complication rate (0-32%). Although the ideal treatment remains debatable, two main procedures are commonly used to manage the majority of mandibular angle fractures that are open reduction and internal fixation by a noncompression miniplate placed on the external oblique ridge with or without a second miniplate on the outer cortex. The purpose of this study was to describe our management of mandibular angle fractures by two noncompression miniplates placed on the outer cortex via a transbuccal approach. Medical records and radiographic examination of 389 patients (258 males [66.3%] and 131 females [33.7%]) operated from January 2000 to December 2012 were retrospectively reviewed. Postoperative complications including malocclusion, infection, wound dehiscence, nonunion, and reoperative surgery were recorded and analyzed. Fifty-three patients developed postoperative complications (overall complication rate: 13.6%). No significant difference was found in the complication rate by age and gender variables and regarding the interval between the trauma and the operation and the presence of the teeth in the line of fracture. A higher rate of complications was found among patients with alcohol/drug addiction and in patients with multiple-site involvement. The findings of this study suggest that the use of two transbuccal miniplates placed on the outer cortex for the internal fixation of mandibular angle fracture provided a low rate of complications. The global incidence of screw loosening, wound dehiscence, plate exposure, infection, reoperation, and plate removal were similar with the data reported in the literature with improved health outcomes, lower postoperative morbidity, and a faster return to normal life.
- Evaluation of Mandibular Anatomy Associated With Bad Splits in Sagittal Split Ramus Osteotomy of Mandible. [Journal Article]
- J Craniofac Surg 2016; 27(5):e500-4JC
- CONCLUSIONS: This study suggests that patients with shorter ramus and low thickness of the buccolingual alveolar region distal to the second molar had a higher risk of bad splits. These anatomic data may help surgeons to choose the safest surgical techniques and best osteotomy sites.
- Lateral Ridge Augmentation with Autogenous Bone Harvested Using Trephine Drills: A Noninvasive Technique. [Journal Article]
- Open Dent J 2016; 10:1-11OD
- CONCLUSIONS: This non-invasive and simple technique provided an acceptable increase in ridge width. As the sample was small, we recommend further clinical investigation with larger samples to confirm that this technique may be used successfully as an alternative to current invasive augmentation methods.
- In Vitro Mechanical Analysis of Different Techniques of Internal Fixation of Combined Mandibular Angle and Body Fractures. [Journal Article]
- J Oral Maxillofac Surg 2016; 74(4):778-85JO
- CONCLUSIONS: Fixation of bilateral mandibular fractures involving the mandibular angle and body using 2 plates in the region of the body and 1 plate in the tension zone in the region of the mandibular angle was the technique that presented the best mechanical resistance.
- Routine removal of the plate after surgical treatment for mandibular angle fracture with a third molar in relation to the fracture line. [Journal Article]
- Ann Maxillofac Surg 2015 Jan-Jun; 5(1):77-81AM
- CONCLUSIONS: Routine removal of the plate after surgical treatment for mandibular angle fractures, simultaneously with extraction of the third molar if indicated, may be beneficial to avoid complications related to the plate and the third molar later in life.

The purpose of this study was to compare one miniplate with two in the management of isolated fractures of the mandibular angle as regards wound healing, failure of hardware, scarring, weakness of the facial nerve, and overall morbidity, by making a systematic review with a meta-analysis. I made a comprehensive electronic search with no date or language restrictions in October 2014. The inclusion criteria were studies in humans, including randomised or quasirandomised controlled trials (RCT), controlled clinical trials (CCT), and retrospective studies that compared the morbidity after treatment of such fractures with one and two miniplates. Ten publications were included: three RCT, three CCT, and four retrospective studies. Three studies showed a low, and seven a moderate, risk of bias. There was a significant difference between one and two miniplates in the incidence of wound healing, failure of hardware, weakness of the facial nerve, and overall complications (p=0.04, p =0.05, p=0.002, and p=0.05, respectively). The result of the meta-analysis showed that one miniplate placed on the external oblique ridge provided a significant reduction in the incidence of wound infection and dehiscence, failure of hardware, and overall complications, compared with two miniplates, one placed on the external oblique ridge and one placed on to the ventral surface of mandible to fix the fracture.
- Mandibular bone block harvesting from the retromolar region: a 10-year prospective clinical study. [Clinical Trial]
- Int J Oral Maxillofac Implants 2015 May-Jun; 30(3):688-97IJ
- CONCLUSIONS: This study demonstrated that relatively large volumes of bone block graft can be retrieved in the mandible with a low complication rate. Reimplantation of half of the bone block offers the possibility for complete regeneration of the donor site.
- [Treatment of adult bimaxillary arch protrusion with micro-implant anchorage]. [Journal Article]
- Shanghai Kou Qiang Yi Xue 2015; 24(1):76-82SK
- CONCLUSIONS: Micro-implant can provide not only excellent skeletal anchorage but also a novel way to distalize the whole dentition efficiently.
- A comparative finite elemental analysis of glass abutment supported and unsupported cantilever fixed partial denture. [Journal Article]
- Dent Mater 2015; 31(5):514-21DM
- CONCLUSIONS: By contacting the mucosa, glass abutments transfer some amount of masticatory load to the residual alveolar ridge, thereby preventing damage to the periodontal microstructures of the terminal abutment. The passive contact of the glass abutment with the mucosa not only preserves the health of the mucosa covering the ridge but also permits easy cleaning. It is possible to increase the success rate of cantilever FPDs by supporting the cantilevered pontic with glass abutments.

- Three dimensional finite element analysis of the stress distribution around the mandibular posterior implant during non-working movement according to the amount of cantilever. [Journal Article]
- J Adv Prosthodont 2014; 6(5):361-71JA
- CONCLUSIONS: The results of this study suggest that for the patient with atrophied alveolar ridge following the loss of molar teeth, von-Mises stress on implant components was the lowest under the 30° oblique load at the 5 mm offset point. Further studies for the various crown height and numbers of occusal points are needed to generalize the conclusion of present study.
