The saddle connective tissue graft: a periodontal plastic surgery technique to obtain soft tissue coronal gain on immediate implants. A case report.

Based on recent studies regarding the advantages of flapless immediate implants on the maintenance of the soft tissue architecture (especially at papillae level) in those situations where it is necessary to extract an anterior tooth, this case report describes a clinical procedure designed to replace a hopeless central incisor (2.1) showing root resorption adjacent to an implant-supported crown (1.1), whose gingival margin is 2 mm coronal regarding the hopeless tooth to be replaced. After the extraction of the hopeless tooth (2.1), a flapless immediate implant was placed. The implant-bone gap was then filled with bone substitute and a palatal connective tissue graft was placed ad modum saddle extending at buccal level from apical to the mucogingival line, sealing the socket and extending until 6 mm at palatal level ad modum saddle. This procedure allowed symmetry of the soft tissue margins between the two implants (1.1 and 2.1) to be obtained as well as the preservation of the inter-implant papillae (1.1).
