the oromandibular-limb hypogenesis syndrome comprises a group of anomalies which simultaneously affect the mandible, tongue, and maxilla with or without reductive limb anomalies. it is characterized by failure of development of the intraoral region and distal extremities. multiple and variable deformities of the mandible, maxilla and tongue may occur in combination with a variety of limb defect...

mandibular incisor extraction in carefully selected cases as an alternative option to four bicuspid extraction or non extraction treatment has been advocated. the purpose of this study was to determine the degree of improvement in occlusion in patients with bolton discrepancy treated by one lower incisor extraction using peer assessment rating index (par indexes).pre and post treatment dental c...

objectives: differential diagnosis of bifid mandibular condyle (bmc) is important, since it may play a role in temporomandibular joint (tmj) dysfunctions and joint symptoms. in addition, radiographic appearance of bmc may mimic tumors and/or fractures. the aim of this study was to evaluate the prevalence and orientation of bmc based on cone beam computed tomography (cbct) scans.   materials and...

objective: t o evaluate the effects of intravenous ketorolac on early postoperative pain in patients with mandibular fractures, who underwent surgical repair. methods: this prospective, randomized, placebo-controlled clinical trial was conducted in shahid rajaei hospital, affiliated with shiraz university of medical sciences during a 1-year period from 2015 to 2016. we included a total number o...

objective: the present study assessed the association of size, axial angulation, developmental stage and bud position of the mandibular third molar with the second molar impaction in patients with mandibular second molar impaction. methods: in this descriptive-analytical study (case-control design), dental records of 5,420 patients in the age range of 12-15 years who underwent orthodontic treat...

MANY APPROACHES FOR CROWDED MANDIBULAR ANTERIOR TEETH ARE CURRENTLY EMPLOYED: distal movement of posterior teeth, lateral movement of canines, labial movement of incisors, interproximal enamel reduction, removal of premolars, removal of one or two incisors, and various combinations of the above. Selecting the best treatment is often difficult, and all guidelines do not apply to every case. Trea...

Here we investigate the roles of the Bone Morphogenetic Protein (BMP) antagonists Chordin and Noggin in development of the mandible, which is derived from the first branchial arch (BA1). Both genes are expressed in the pharynx during early mandibular outgrowth and later in the mandibular process. Mice mutant for either Nog or Chd have only mild mandibular defects; however, pups of the genotype ...

The mandibular foramen is a landmark for procedures like inferior alveolar nerve block, mandibular implant treatment, and mandibular osteotomies. The present study was aimed to identify the precise location of the mandibular foramen and the incidence of accessory mandibular foramen in dry adult mandibles of South Indian population. The distance of mandibular foramen from the anterior border of ...

Mandibular fracture treatments are to improve the patients function and aesthetics, but it is not uncommon that postoperative complications be present. Postoperative include surgical site infection, nonunion, malunion, malocclusion, nerve injury, scar tissue, Temporo-Mandibular Joint Disorder (TMD), as well dental problem. This literature review aimed understand describe of mandibular fractures...

OBJECTIVE The aim of this study was to investigate the three-dimensional (3D) position of the center of resistance of 4 mandibular anterior teeth, 6 mandibular anterior teeth, and the complete mandibular dentition by using 3D finite-element analysis. METHODS Finite-element models included the complete mandibular dentition, periodontal ligament, and alveolar bone. The crowns of teeth in each g...
