accurately localizing the mental foramen and mandibular canal is important when administering local anesthesia and performing surgery; therefore, knowing the normal range of the possible locations is essential. our purpose was to assess the location of the mental foramen and mandibular canal in an iranian population using panoramic radiography.standard panoramic radiographies were performed. th...

cone beam computed tomography is a useful technique for imaging the craniofacial lesions. it produces more realistic images that facilitate interpretation. juvenile ossifying fibroma (jof) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. mandibular lesions can be seen in 10% of the cases.in both jaws, it has a predilection for the...

It is well known that mandible bone is formed by intramembranous ossification. Mandible condyle cartilage and angular cartilage are recognized as secondary cartilage, which differs from primary cartilage in morphological and biochemical organization. These are interesting research subjects from a clinical point of view as they compose the TMJ. We examined the mandible, mandible condyle cartilag...

objectives: this study was designed to assess the changes of the mandible of patients who underwent orthodontic treatment with or without extraction of four premolars. materials and methods: eighteen class i bimaxillary protrusion patients treated with extraction of four first premolars and retraction of anterior teeth and 18 class i non-extraction patients with a mean age of 16.38±0.4 years we...

conclusions mandibular fractures can be complicated and demanding, and have a compelling impact on patients’ quality of life. our study reported that parasymphysis was the most common region involved in mandible fractures. results a total of 653 subjects had mandibular fractures, out of which 574 were males. the mean age of the participants was 31.54 ± 13.07. the majority of the subjects were b...

conclusions using 3d ct scan to produce a prototype and reconstruct the mandible with a custom-made ti-mesh tray was useful. patient was followed up for 14 months. mandibular deviation was largely corrected. there was no complication in the donor site. no sign of extra or intra oral fistula, dehiscence or infection was detected. ti-mesh technique has three major advantages over other methods: i...

pathologic fractures of the jaw are usually associated with aggressive, destructive lesions or malignant lesions of the jaws. aneurysmal bone cysts (abc) of the jaws are benign lesions which normally do not cause destruction to such an extent. this article reports a relatively aggressive abc of the mandible in a 19 year-old male which destroyed the buccal and lingual cortices as well as the inf...

schwannoma(neurilemmoma) is a benign tumor originates from schwann cells. ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. the mandible is the most common site of occurrence for this lesion. we report a rare case of intraosseous ancient schwa...

The aim of this study is to determine whether or not the breed and sex factors have an effect on shape in mandibles Hamdani Awassi sheep. A total 31 were used. samples analyzed via geometric morphometric methods by using semilandmark. In study, it was determined that primary principal component accounted for 36.52% difference. According analysis, clustered significantly terms breed; whereas, th...
