Abstract

Abstract
Objectives: This study was designed for radiographic and clinical evaluation of basal dental implant placement in atrophic alveolar ridg.
Subjects and methods: The present study was conducted on twenty implants for individuals presented with sever bony defect and seeking for dental implant. Preoperative clinical evaluation was carried out; both medical and dental histories were taken and investigated. Evaluation of the interocclusal space for the placement of the prosthesis. panoramic radiograph and CBCT scan for ridge evaluation and planning, Measuring height and width of residual alveolar ridge was performed in CBCT. Surgical stent was fabricated with aid of CBCT to act as a guide for simple and accurate orientation and angulation during implant placement and to preserve vital structures. After surgery, initial stability was estimated by periotest, immediate postsurgical panoramic and CBCT radiograph to evaluate position of the implant. Follow up after 6 months was done to denote stability and marginal bone loss.
Results Periotest reagings refer to excellent stability immediatly after implant and also at six months later.
Conclusion: Good stability in basal implants is related to its design permitting cortical bone engagement. Furthermore, it is a compression screw thus it corticalizes the spongious bone around the implant. Basal implant can be used successfully in severely atrophied ridge and compromised bone. Basal implants are used to avoid any extra surgical procedures, because these implants anchor reliably in resorption stable cortical bone and they are loaded immediatly after surgery.
