: Mandibular reconstruction in pediatric patients is controversial. The scant pediatric experience and the infrequent occurrence of this type of pathology in children complicate therapeutic decisions. The literature contains different treatment protocols and describes the bone graft alternatives to be used. MATERIALS AND METHOD: This is a retrospective review of patients under the age of 15 who were subjected to resection and reconstruction. RESULTS: A total of 18 patients were included in the study: 8 women and 10 men...

REVIEW
Galina Shapiro, Raphael Lieber, Dan Gazit, Gadi Pelled
PURPOSE OF REVIEW: The purpose of this review is to discuss the recent advances in gene therapy as a treatment for bone regeneration. While most fractures heal spontaneously, patients who present with fracture nonunion suffer from prolonged pain, disability, and often require additional operations to regain musculoskeletal function. RECENT FINDINGS: In the last few years, BMP gene delivery by means of electroporation and sonoporation resulted in repair of nonunion bone defects in mice, rats, and minipigs...

The facial fractures in pediatric patients are rare, and they can need an immediate treatment to recover the function and aesthetic to the young patients. However, the open reduction internal fixation is controversial in pediatrics; it can be effectiveness to treat complex mandible fractures. Therefore, we present a case of a pediatric patient with a complex mandible fracture caused by an auto accident. The immediate treatment was successful with the use of open reduction internal fixation.

Severely atrophic mandible fractures are frequently a challenge to treat. Virtual surgical planning (VSP) uses three-dimensional computed tomographic (CT) scans that can be translated into stereolithographic models to fabricate surgical templates, facilitating intraoperative procedures. The purpose of this article is to describe the reconstruction of two cases of severe atrophic mandible fracture using VSP. Two elderly edentulous/partially dentate patients who presented with fractures of their mandibles and who underwent reconstruction using VSP were included...

Payam Farzad
The use of virtual surgical planning and computer-aided design/computer-aided manufacturing has previously been reported to enhance the planning for the reconstruction of mandibular continuity defects and to reduce surgical time. Reported is a case of a large keratocystic odontogenic tumor (KOT) affecting right hemimandible including the condylar neck. This case was initially reconstructed with a condyle-bearing reconstruction plate, but because of fatigue fracture 15 years later, a new reconstruction with a custom-made total joint temporomandibular prosthesis was performed...

INTRODUCTION: The purpose of this study was to assess the influence of tooth orientation in relation to the projection plane of the x-rays on the detection of vertical root fracture (VRF) with different filling materials using cone-beam computed tomographic (CBCT) imaging. METHODS: Thirty single-rooted human teeth were endodontically instrumented, and VRF was induced in half of the sample. The roots were individually placed in the dental socket of a phantom head composed of a dry human skull and mandible, and CBCT images were obtained of each root with the longitudinal axis in 2 orientations: perpendicular and parallel to the projection plane of the x-rays...

In 2009, a pit burial dated to the Bronze Age was excavated in Monte do Gato de Cima 3 (Portugal). The purpose of this paper is to describe the pathological absence of the left mandibular condyle noted in an adult male skeleton and to discuss possible diagnoses, including subcondylar fracture, cystic defect, congenital absence, condylar aplasia and mandibular condylysis. The most likely explanation for the pathological alteration is subcondylar fracture with non-union. Although the occurrence of non-union and slight osteoarthritic alterations in the left glenoid fossa were evident, this mandible was likely functional, as can be inferred from dental wear and muscle attachment sites...

Taurodontism is considered a dental anomaly responsible for a morphoanatomical change in the shape of the tooth in which the roots are reduced in size but the body of the tooth is enlarged and bulky. The aim of this paper is to present a case of a 25-year-old female patient with taurodontism of mandibular partially erupted third molars, presenting a high risk of angle fracture and paresthesia in case of their removal, treated by means of coronectomy. The postoperative period was uneventful and the patient remained in follow-up for 12 months...

This study aims to identify and distinguish various factors that may influence the clinical symptoms (limited mouth opening and malocclusion) in patients with maxillofacial fractures. From January 2000 to December 2009, 963 patients with maxillofacial fractures were enrolled in this statistical study to aid in evaluating the association between various risk factors and clinical symptoms. Patients with fractured posterior mandibles tended to experience serious limitation in mouth opening. Patients who sustained coronoid fractures have the highest risk of serious limitation in mouth opening (OR = 9...

The management of fractured mandibles typically involves admission and operation at the time of presentation. While this should involve only a short stay in hospital these patients are surgically stable, and so priority is often given to more urgent cases. We retrospectively evaluated the postoperative medical requirements of patients who were operated on at Fiona Stanley Hospital, Perth, Western Australia between 1 January 2015 and 31 December 2016. Patients were excluded if they had had multiple facial fractures, multiple injuries, had fractures that were comminuted or in edentulous mandibles, and those who had been in hospital for preoperative medical investigations and care...

PURPOSE: The utility of postoperative mandibulomaxillary fixation (MMF) after open reduction and internal fixation (ORIF) of mandible fractures is debated. The purpose of this study is to analyze if patients undergoing ORIF with postoperative MMF have improved outcome compared with those treated with ORIF alone. METHODS: A retrospective study was performed on patients who underwent ORIF of isolated mandibular fractures. Patients were divided into those placed in MMF postoperatively (ORIF with MMF) and those who were not (ORIF only)...

PURPOSE: The incidence of fractures of edentulous mandibles is relatively low. Knowledge about the management of these fractured edentulous mandibles relies heavily on case reports and observational studies. On the basis of the current literature, we compiled a treatment protocol for fractures of the edentulous mandible and hypothesized that this protocol would result in fewer complications. PATIENTS AND METHODS: We conducted a retrospective cohort study of edentulous patients with mandibular fractures...
