The aim of this study was to compare the initial orthopaedic displacement of the maxilla in vivo and the longitudinal changes after a forward force application. The sample consisted of five 1-year-old dogs. An anterior force of 5 N on the maxilla was applied by a coil spring system pushing between Brånemark implants and a maxillary splint. The initial displacement of the maxilla after force app...

Midface bones are an unusual site for primary presentation and relapse in acute lymphoblastic leukemia. Herein, we describe a case of acute pre B cell lymphoblastic leukemia with leukemic infiltration of maxilla and bone marrow involvement. At the time of relapse, the patient presented again with maxilla involvement and the phenotype changed to biphenotypic lymphoblastic leukemia. Our case sug...

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...

anthropometry, a useful method for evaluating craniofacial soft tissues, makes the quantitative description of the face possible. it also assesses the degree of disharmony and imbalance in the growth and development of the face. the aim of this study was to examine the overall common age-related changes of nasomaxillary complex of adolescent boys in northeast iran. three- hundred- twelve 12 to ...

mesenchymal chondrosarcoma (mc) is an uncommon tumor with an aggressive behaviour. we present two cases of mc. the first one is a unique case of mc of the maxilla metastasized from the clavicle. the second describes mc in the mandible with extensive involvement of the condyle. a 31-year-old male and a 22-year-old male presented to saveetha dental college, with a 2-month history of progressive m...

introduction: many patients suffer from mild, moderate or severe pain during or after root canal therapy. theoretically, post-operative pain control can be achieved by using long-acting local anesthetics. the aim of this study was to evaluate the efficacy of a long acting anesthesia, bupivacaine, on preventing post-operative pain associated with endodontic treatment, and to compare it with lido...

objectives: implant primary stability is one of the important factors in achieving implant success. the osteotome technique may improve primary stability in patients with poor bone quality. the aim of this study was to compare implant stability using two different techniques namely osteotome versus conventional drilling in the posterior maxilla. materials and methods: in this controlled randomi...

introdouction: the mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. the position of objects that create a ghost image can differ when using various devices. the purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a cranex d digital panoramic machine. materials and methods: t...
