Introduction: The use of dental implants to restore missing teeth has become increasingly widespread over the past two decades. Dental MSCT plays an important role in the preoperative planning of dental implants because it provides accurate measurement of the width and depth of the edentulous ridge as well as the bone density. And postoperatively, dental MSCT images can show the failure of an endosseous implant to osseointegrate, improper placement of an implant, and violation of important structures. Aim of the work: Is to determine the success of dental implants following pre-operative multi-slice dental CT planning and for early detection of post-operative complications. Methods: The study included 25 patients that were divided in to 2 groups, Group I included 14 partially edentulous patients who underwent pre and post- operative dental MSCT, while group II included 11patients that already have dental implants and underwent post-operative dental MSCT using16-slice helical CT scanner. Results: There is highly significant (P < 0.001) relation between preoperative dental MSCT assessment and postoperative results and dental MSCT was very accurate in the evaluation of osseointegration and very sensitive in the detection of postoperative complications. Conclusion: Dental MSCT is a promising method that can be used as an imaging tool in the preoperative planning and postoperative assessment of dental implants.
