Abstract
Maxillary anterior implants should be both aesthetically perfect and functionally successful. To achieve aesthetic success in anterior maxillary implants, immediate implant placement after tooth extraction to prevent bone resorption, and flapless implant surgery to minimize soft tissue trauma, can be considered as treatment options. Immediate implant placement, however, cannot be performed easily when infection occurs in extraction sockets. Extensive flap elevation is necessary in compromised bone height or width areas. The entire treatment procedure, from tooth extraction and implant placement to final prosthesis fabrication, takes a lot of effort in terms of obtaining the proper esthetic results in the anterior maxillary implants. If massive bone resorption occurs, guided bone regeneration and tissue graft surgery is performed. In such cases, provisional restoration can be used to initiate guided soft tissue healing for natural looking, esthetically pleasing soft tissue contours. This paper presents the case of a patient who needed implant treatment following trauma to both maxillary central incisors. In this case, infection in an extraction socket impeded immediate implant placement, which led to the use of the Bio-Col alveolar ridge preservation technique suggested by Sclar in 2003 to obtain the best possible esthetic results. Using the Bio-Col technique, interim provisional restoration was used to prepare extraction sockets for implant placement. Flapless implant surgery to preserve the scalloped-shaped gingiva was originally planned. However, buccal bone resorption was observed during surgery, which led to flap elevation and guided bone regeneration, resulting in limited esthetic results. Provisional restorations were customized to guide natural soft tissue architecture following implant placement. Four months after provisional restoration, the contour of the gingiva was stabilized enough for additional gingival recession not to occur. Therefore, the final restorations were delivered using zirconia abutments and crowns.
