Immediate implant placement in extraction sockets with buccal bone dehiscence: A case study

Background: Immediate implant placement (IIP) has been associated with a higher risk of esthetic complications and particularly buccal mucosal recession, which can be more pronounced in non-intact sockets or in the presence of thin phenotype in the esthetic zone. Nevertheless, multiple techniques have been published to address IIP in non-intact alveolar sockets with favorable outcomes. The purpose of this study is to present an approach on IIP in sites with buccal bone dehiscence. Methods: Three patients requiring extraction of one or multiple teeth in the presence of buccal bone dehiscence were treated with flapless extractions, IIP, guided bone regeneration (GBR), and connective tissue grafting (CTG) through a tunneling approach with a simultaneous use of custom healing abutments. Results: All sites exhibited 1-2 mm of buccal bone thickness at the level of the implant platform, as well as significant buccal soft tissue thickness with no recession and a favorable development of the emergence profile at 4 months to a year post implant placement. Conclusions: IIP in sockets with buccal bone dehiscence can be managed by means of a flapless extraction, GBR and CTG through a tunneling approach exhibiting favorable hard and soft tissue responses.
