The purpose of this study was to evaluate the precision of dimensional measurements of the mandible on orthopantomographic images and thus to evaluate their dimensional reliability. Different distances denoted by metal markers were measured on 25 dry mandibles. The same mandibles were then positioned in an orthopantomographic machine, and radiographic images of them were made. Measurements of t...

Fractures of the mandible occur with a greater frequency in the elderly. This study reports three cases of edentulous atrophic mandible fracture in elderly patients treated with open reduction technique. Three patients who presented with edentulous atrophic mandible fractures underwent surgical management using open reduction and internal fixation. After treatment, clinical evaluations and post...

Microdamage reduces bone mechanical properties and thus could possibly contribute to implant failure. The objective of this study was to investigate whether the diameter of mini-implants (MI) affects microdamage generation and whether this differs between the mandible and maxilla due to their contrasting cortical thicknesses. Methods: Maxillary and mandibular quadrants of 5 dogs were randomly a...

BACKGROUND The temporomandibular joint (TMJ) may be affected unilaterally or bilaterally in the course of juvenile idiopathic arthritis (JIA). Permanent complications involve joint damage or stiffness and disorders in the development of the mandible, such as micrognathia, posterior rotation of the mandible, crowding and protrusion of the front teeth and malocclusion. OBJECTIVES The aim of the...

Aggressive central giant cell granuloma (ACGCG) is usually found in younger patients and is painful, grows rapidly, larger overall, often causes cortical perforation, root resorption and has a tendency to recur. This article is a case report of ACGCG in mandible. A girl 12 years old had features of typical giant cell reparative granuloma in the anterior mandible. After incision biopsy, she repo...

This thesis describes a methodology for forensic craniofacial reconstruction, de ned as the reproduction a subject's facial appearance from the skull and mandible for the purposes of identi cation. The focus of this work is on reproducing three dimensional facial shape from the shape of the skull and mandible of a subject. This task can be broken into two parts. First, a technique for determini...

The mandible plays an important role in mastication, speech and facial cosmesis. Apart from direct involvement by oral malignancies, the mandible used to be excised in oral cancers due to its proximity to the tumour, for adequate resection margins and for fear of recurrence as cancer was thought to spread via the periosteal lymphatics. However, with better understanding of spread of oral cancer...

BACKGROUND The most frequent cause of defect in the mandible is tumor-related surgery. Larger defects or anterior arch defects cause severe morbidity due to disturbances in function and esthetics. OBJECTIVES To assess the outcome of free tissue transfer for mandible reconstruction. METHODS Since 1998 we operated on 11 patients with mandible defects using the fibula flap as the reconstructio...

BACKGROUND This study presents an alternative in reconstruction, using free skin flaps in combination with pedicled mandible bone flaps for complex lateral mandibular defects. METHODS In all, 13 patients were included in this prospective study. Pedicled mandible myo-osseous flaps were used for reconstruction of bone defects of the lateral mandible in combination with free skin flaps, includin...
