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...

in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test...

background: arterial damage is sometimes associated with supracondylar fractures of the humerus. diagnosis and careful management of the fracture and arterial repair is crucial. objectives: the aim of this study was to determine the prevalence and outcome of supracondylar fractures of the humerus with signs and symptoms of limb ischemia, before and after arterial decompression or arterial recon...

osteosarcoma (os) is a malignant mesenchymal tumor, which rarely occurs in the maxilla. although variable histologic and radiographic features of os have been reported previously, in the majority of the cases painful swelling of the jaw is mentioned as the first clinical presentation. furthermore, early diagnosis and wide surgical resection of the tumor are the most important determinant factor...

abstract patella is a relative uncommon site for chondroblastoma. most of cases of chondroblastoma in patella reported in literature are treated with patellectomy. we treated a large chondroblastic lesion in patella of an 18- year-old male with curettage, burring & bone graft and the result was satisfactory after 3 years post operation.

BACKGROUND: Dental disease, trauma and maxillofacial surgeries can cause alveolar bone defects. Among different kinds of treatment, autogenous bone grafts is accepted as a golden standard. On the other hand, because of limitation of treatment with autogenous bone grafts, osteogenic cells derived from stem cells are suggested. OBJECTIVES: The aim of this study was to compare the mean density of ...

statement of problem: placement of mini-dental implants when single-tooth restorations are needed and the space is not sufficient to insert a standard diameter implant is indicated. there are many different mini-implant brands with various materials and surface characteristics; however, there are just few studies comparing them with each other. objectives: in this study, finite element analysis...
