OBJECTIVES: A variety of mechanical processes can result in antemortem dental chipping. In this study, chipping data in the teeth of Homo naledi are compared with those of other pertinent dental samples to give insight into their etiology. MATERIALS AND METHODS: Permanent teeth with complete crowns evidencing occlusal wear were examined macroscopically. The location, number, and severity of fractures were recorded and compared to those found in samples of two other South African fossil hominin species and in samples of nonhuman primates (n = 3) and recent humans (n = 7)...

PURPOSE: To describe an unusual case of mandibular fracture after osseointegrated dental implant removal placed after inferior alveolar nerve transposition. REPORT OF CASE: The patient underwent inferior nerve transposition for implant placement due to lack of interarch space. Two months after metal-ceramic crowns installation, the patient began to complain of pain in the region of the implant. In an attempt to remove the implant, there was a fracture of the implant, and only two third of it was removed, leaving only the apical portion of the implant in the mandible...

Fractures of the mandible are relatively less frequent in children when compared to adults. The anatomic features of children are protected. Children have a higher adaptation to maxillofacial fractures compared to adults. Treatment principles of mandibular fractures in children differ from that of adults due to concerns regarding mandibular growth and the developing dentition. A case of a 6-year-old boy with fractured mandibular symphysis managed by closed reduction using a vacuum formed thermoplastic splint and circummandibular wiring is presented...

The association of traumatic head injury (THI) with maxillofacial fractures (MFF) is a major health concern worldwide. In spite of the close anatomical proximity of maxillofacial bones to the cranium, the association of THI with MFF is controversial. The aim of this study was to assess the association between traumatic head injuries (THI) and maxillofacial fractures (MFF). Other factors associated with THI in patients with MFF were also investigated MATERIALS AND METHODS: A hospital-based retrospective study was conducted at the OMFS Unit, Hospital USM, Kelantan, Malaysia...

PURPOSE: Fracture lines in unfavorable locations are referred to as "bad splits" in a mandibular sagittal split osteotomy (SSO). Several modifications of the technique by Obwegeser have been introduced to minimize this risk. This in vitro study was performed to determine whether the shape of the osteotomy cut affects the torque and the fracture pattern of an SSO in pig mandibles. MATERIALS AND METHODS: In a split-mouth model, 16 mandibles were split according to the Hunsuck-Dal Pont modification of the Obwegeser technique...

REVIEW
Kausar Ali, Salvatore C Lettieri
Traumatic panfacial fracture repair is one of the most complex and challenging reconstructive procedures to perform. Several principles permeate throughout literature regarding the repair of panfacial injuries in a stepwise fashion. The primary goal of management in most of these approaches is to restore the occlusal relationship at the beginning of sequential repair so that other structures can fall into alignment. Through proper positioning of the occlusion and the mandibular-maxillary unit with the skull base, the spatial relationships and stability of midface buttresses and pillars can then be re-established...

PURPOSE: The immediate placement of single postextractive implants is increasing in the everyday clinical practice. Due to insufficient bone tissue volume, proper primary stability, essential for subsequent osseointegration, is sometimes not reached. The aim of this work was to compare two different approaches: implant bed preparation before and after root extraction. MATERIALS AND METHODS: Twenty-two patients of both sexes were selected who needed an implant-prosthetic rehabilitation of the fractured first mandibular molar or presented an untreatable endodontic pathology...

Facial fractures in children are rare. Lack of pneumatization, fat pockets, mixed dentition, contribute to the elasticity and bone stability. When mandibular fractures occur in children, most often involve the condyle by indirect trauma. Such fractures are the center of discussion on the form of treatment if this should be performed conservatively, or held the reduction and fixation of the fracture with surgical exposure of the fragments. In condylar fractures in children, in most patients, the proposed treatment is closed reduction...

There is a subgroup of patients with mandibular fractures who could safely and effectively be managed in an outpatient day-care unit. Suitability depends on medical, social, and operative factors, and identification of the correct criteria will govern management after that in the emergency department. Reduced use of beds would lead to less money being spent on emergency treatment, and increased capacity for elective surgery. The aims of this study were to identify a group of patients with mandibular fractures whose duration of operation and period of recovery would be suitable for treatment in the day-care unit, and to evaluate the potential financial benefits...
