background and objectives: split sagittal osteotomy is a common operation that may induce inferior alveolar nerve (ian) damage, potentially leading to sensory deficit, numbness, and pain. investigations in iran to evaluate the adverse effects of sagittal split osteotomy surgery are rare so questions have been raised about the success rate of operation and the frequency of unwilling outcome. to ...

BACKGROUND There is no accepted landmark for the mechanical axis of the femoral axis in sagittal plane in conventional total knee arthroplasty. METHODS As palpable anatomic landmarks of the femur, lateral epicondyle, and anterior margin of the greater trochanter were identified. The line connecting these two landmarks was defined as the "palpable sagittal axis". The mechanical axis of the fem...

Introduction -Transverse discrepancies of the maxilla are one most prevalent skeletal problems. Due to drawbacks conventional RPE and invasive surgical expansion methods alternative were developed such as Mini Implant-supported rapid maxillary (MARPE).Haas17 , Davis Kronman18, Akkaya et al19 many other studies have reported response after MARPE on sagittal dimensions, but their results inconclu...

BACKGROUND The aim of the survey was to obtain information on the treatment plan preferences, mechanics and characteristics of temporary anchorage device (TAD) application using a single case presented to orthodontists in Switzerland. METHODS A structured questionnaire to be completed by all study participants with case-specific (treatment plan including mechanics and TAD usage) and general q...

T1 sagittal angle has been reported to be used as a parameter for assessing sagittal balance and cervical lordosis. However, no study has been performed to explore the relationship between T1 sagittal angle and sagittal balance, and whether T1 sagittal angle could be used for osteotomy guidelines remains unknown. The aim of our study is to explore the relationship between T1 sagittal angle and ...

abstract objective: to present the changes in projected thoracic hypokyphosis and the behavior of lumbar lordosis within and below the fusion and to compare these changes between the harrington rod (hr) and posterior multisegmented hook instrumentation. methods: 178 patients with idiopathic scoliosis, who had undergone posterior spinal fusion with harrington technique (106 patients) or multiseg...
