The novel implant (hybrid implant) showed good stability and minimum patient discomfort during one year postoperative period evaluation. The implant system leads to new prospect in the field of prosthetic rehabilitation.

Variations affecting the growth centers can severely affect the normal formation and subsequent function of vital musculoskeletal structures. We report a case of bilateral condylar atrophy with a history of juvenile arthritis (JA) resulting in progressive obstructive sleep apnea (OSA) in adulthood. In addition to this, the case report emphasizes the role of temporomandibular joint replacement and advancement of the mandible to correct progressive OSA secondary to idiopathic JA. Computed tomography revealed micrognathia, condylar hypoplasia, and decreased pharyngeal airway space. The resultant increase in the retrolingual-pharyngeal airway space following the surgery, helped to completely resolve the presenting symptoms. It is hoped that the described technique could be used in similar cases with a predictable outcome.

Aims:The aim of the study is to audit the titanium reconstruction of jaw defects in benign conditions in Christian Medical College and Hospital, Vellore.Methods and Material:A retrospective study of titanium reconstruction of mandibular defects due to jaw lesions at Christian Medical College and Hospital, Vellore, India, between May 2008 and May 2011.Results:Mouth opening, facial symmetry, occlusion, chewing ability, plate exposure and patient satisfaction were used as outcome measures.Conclusions:The three-dimensional titanium plate is a reasonable material for immediate mandible reconstruction after surgical resection of benign jaw pathologies.

In spite of the obvious advantages, the practice of immediate loading is limited due to apprehension associated with compromised bone response and a higher rate of bone loss around an immediately loaded implant. The mechanical basis for the concept of "platform switching" in immediately loaded situation is analyzed in this context. The results of this limited investigation indicated that the ideal values of microstrain (50-3000 microstrain) can be exhibited by platform switching of dental implants (with an abutment-implant diameter difference of 1 mm) and can be considered as a better alternative for prevention of crestal bone loss when compared to non-platform-switched implants.
