Abstract

Introduction: There will almost always be gaps between cylindrical or screw shaped prefabricated implant surface and funnel-shaped tooth socket when an implant is placed immediately after tooth extraction. Hence expensive and difficult bone grafting is required. A custom fabricated implant will be a pragmatic solution for this limitation. The hypothesis: First step following extraction of a tooth is data capture or scanning via a 3D scan method e.g. coordinate measuring machine or non-contact laser scanners such as triangulation range finder. Second step is reconstruction or modeling via editable CAD (computer-aided design) model, allowing us to add retentive holes and correction of implant angle. Third step is fabrication via CAM (computer aided manufacturing) followed by plasma cleaning process. Fourth step is insertion of the CAD/CAM custom fabricated one-stage implant in the fresh tooth socket. Optimal time for this step is 24-48 hours after extraction. The custom fabricated implant should not load 3-4 months. Usage of chlorhexidine mouth-rinse or chewing gum twice daily for 2 weeks and, in some cases oral antibiotic is recommended. Evaluation of the hypothesis: Contemporary dental implant system faced with several clinical and anatomical limitations such is low sinuses or nerve bundles. Complex and expensive surgical procedures such as nerve repositioning and sinus lift are frequently required. With custom fabricated implant we can overcome several of these limitations because insertion of custom fabricated implant will perform before alveolar bone recession. © 2010 Dunning D, et al.
