A single center, randomized controlled, parallel-arm study is planned to investigate esthetic outcomes after immediate placement and restoration in the esthetic zone. Forty adult patients who have a hopeless maxillary anterior or premolar tooth, with intact adjacent teeth will be enrolled. A signed written informed consent will be obtained after he or she has been given verbal and written information describing the nature and duration of the study. Subjects will not be screened or treated until an informed consent has been obtained. Patient information will be protected according to the privacy regulations of the Federal Health Insurance Portability and Accountability Act of 1996 (HIPAA).
The enrolled patients will be randomly placed into one of two treatment groups, immediate implant placement (IIP) and restoration group (IR) or the IIP + delayed restoration group (DR). For all patients, the hopeless tooth will be extracted atraumatically and an implant placed immediately. The decision will be made randomly to either restoring the implant immediately (Test group) with a provisional crown or restoring the implant at 4 months after implant placement (Control group). Outcome analyses will be performed until approximately 1-year after the implant surgery and primarily evaluate clinical and radiographic parameters to determine the esthetic outcomes of immediately restored IIP implants, in comparison to those immediately placed but restored in a delayed approach.
