Resorption of the dentoalveolar bone and collapse of the gingival ridge following tooth loss often results in aesthetic compromise and inadequate bone for "prosthetically driven" implant placement. Preventing alveolar bone resorption with a conservative procedure at the time of extraction can enhance aesthetics and reduce the duration and extent of treatment required for implant placement. This article describes the aesthetic management of extraction sites using a conservative bone grafting procedure at the time of extraction for implant site development. The case presented demonstrates staged and delayed implant placement techniques.

After tooth loss, alveolar bone resorption occurs and causes soft tissue collapse. In the anterior maxilla, this situation becomes a great challenge. Bone volume must be reestablished to allow for proper implant placement. Another challenge is achieving primary closure and improving soft tissue esthetics. Nine patients who were partially edentulous in the anterior maxilla and received 10 palatal incisive vessel-based connective tissue flaps were included in this study. Primary closure was successfully achieved in four patients who received simultaneous onlay block grafting in the surgical area. Total treatment time was shortened as an added benefit, since a secondary procedure for soft tissue augmentation was not necessary. In two patients with improper implant angulation, this technique resulted in improved esthetics.

Implant placement in maxillary anterior region has most aesthetic challenges in implant dentistry because tooth loss lead to bone resorption and collapse of gingival architecture, which lead to aesthetic compromise and inadequate bone for implant placement. Immediate implant placement into fresh extraction socket reduces the treatment time, cost, preserved the gingival aesthetic and increases the comfort of the patient. This article describes the procedure for immediate implant placement in fresh extraction socket and early loading of implant with zirconia crown. Clinical and radiographic examination revealed width and length of the tooth for selecting implant size and design. Cement retained zirconia crown was used for early loading. Implant was successfully loaded and was functional during 36 months follow up period. Immediate placement and early loading of dental implant provides advantages like fewer surgical procedures, shorter treatment time, and improved aesthetic and psychological confidence.

Achieving successful long-term esthetic outcomes in implant dentistry requires that the height and width of the facial or buccal alveolar bone wall and, subsequently, the peri-implant tissues be maintained. Partial extraction therapy (PET) can be used to reduce the risk of facio-lingual collapse after tooth loss and improve the preservation of alveolar bone height and blood supply. This article demonstrates the use of PET for treatment of a hopeless tooth in the esthetic zone. After removal of the fractured maxillary central incisor, an implant was placed and restored with excellent esthetic, functional, and periodontal results.
