title: Self-bone graft and simultaneous application of implants in the upper jawbone. (Fit lock technique).
abstract: The implant-supported rehabilitation ofposterosuperior sectors may be sometimes conditioned by the pneumatization of the para-nasal sinuses, which decreases the possibility of implant placement when the bone height is < or = 4 mm. (prerequisite for primary stabilization). Sinus lift surgery with simultaneous application of implants is the procedure which provides the best chance of success compared to the application of the filling material only. There are many surgical techniques which combine autogenous bone grafting (ilium crest, calvaria,fibula) with implant placement. The objective of this report is to present a new technique which aims to minimize invasive bone grafting and patient morbidity. The authors performed a longitudinal study on 21 cases with a 94.5% success rate, exemplified by one clinical case. The advantages of this technique are: 1) Functional and anatomical recovery of the jaw cavity. 2) Simultaneous application of implants when the bone is < or = 4mm. 3) Reduction of surgical times. 4) Reduced patient morbidity. 5) Local anesthesia.
