Two new species of the subfamily Cypricercinae McKenzie, 1971 are described from Western part Thailand: Pseudostrandesia ratchaburiensis sp. nov. and Strandesia prachuapensis is mainly characterized by a flange on antero-ventral left valve (LV), markedly large ? seta mandibular (Md) palp, serrated bristles third endite maxillula (Mx1), slender caudal ramus (CR) with long claw Ga (length ca half...

PURPOSE Two common treatments of temporomandibular joint ankylosis are gap arthroplasty and ankylosis resection and reconstruction of the ramus-condyle unit with a costochondral graft. The purpose of the present study was to answer the following clinical question: "Among patients with temporomandibular joint ankylosis, do those patients who undergo gap arthroplasty, compared with those who unde...

PURPOSE The purposes of the present study were: to compare the resonance frequency analysis (RFA) values of implant placed in either ramus or calvaria block grafts; and to determine if implant diameter influences RFA implant stability quotient (ISQ) value. MATERIAL AND METHODS This was a retrospective study that included 16 consecutives healthy patients treated with autogenous onlay block gra...

BACKGROUND The placement of endosseous implants in edentulous areas is frequently limited by inadequate bone volume of the residual ridge. Local bone grafts from the mandible are a convenient source of autogenous bone for alveolar reconstruction prior to implant placement. PURPOSE The aim of the present study was to document and compare the morbidity and the frequency of complications occurri...

Considerable variation exists in mandibular ramus form among primates, particularly great apes and humans. Recent analyses of adult ramal morphology have suggested that features on the ramus, especially the coronoid process and sigmoid notch, can be treated as phylogenetic characters that can be used to reconstruct relationships among great ape and fossil hominin taxa. Others have contended tha...

In this article, we describe endoscopic-assisted medial ramus osteotomy during sagittal split ramus osteotomy (SSRO). Surgical repositioning of the mandible by bilateral SSRO has become a safer and more reliable procedure through ingenuity of surgical methods, development of special instruments and improvement of surgical skills. The horizontal medial osteotomy should be located at or just abov...

A new species of the genus Gammarus Fabricius, 1775 is described from Lake Tong Tso, an extreme high-altitude lake in Qinghai-Tibetan Plateau. pontual sp. nov. considered part lacustris G.O. Sars, 1863 group, which characterized by having inner ramus uropod 3 longer than half length outer ramus, and both rami covered with plumose setae. The stands apart their congeners, mainly, following combin...

A static, unilateral, and focal bone depression located lingually within the ascending ramus, identical to the Stafne's bone cavity of the angle of the mandible, is being reported. During development of the mandible, submandibular gland inclusion may lead to the formation of a lingual concavity, which could contain fatty tissue, blood vessels, or soft tissue. However, similar occurrences in the...
