Abstract

Tooth extraction causes major changes to the ridge, rendering implant placement a more challenging procedure. Proper management of the socket is necessary to ensure sufficient bone and soft tissue for a successful implant-supported prosthesis. This article presents a practical approach for autologous hard and soft tissue grafting. A soft and hard tissue graft is harvested in one piece from the maxillary tuberosity and stabilized in the extraction socket.

Highlights

Placing an implant in the aesthetic zone is a challenging procedure
Several treatments following tooth extraction are available: immediate or delayed implant placement with or without bone and/or soft tissue augmentation, and socket preservation followed by a delayed implant placement
Grades I and II with thick biotype are eligible for immediate implant placement, while grade II with thin biotype and grade III, a socket preservation is advisable [3]

Summary

Background

Placing an implant in the aesthetic zone is a challenging procedure. Following a tooth extraction, dimensional changes to the ridge occur, as a result of the healing process. Several treatments following tooth extraction are available: immediate or delayed implant placement with or without bone and/or soft tissue augmentation, and socket preservation followed by a delayed implant placement. Several biomaterials have been applied in alveolar ridge preservation, alone or in combination They included xenografts [8, 9], allografts [10, 11], alloplastic material, synthetic magnesiumenriched hydroxyapatite [12], recombinant morphogenetic protein-2 (rh-BMP2) [13], autologous bone marrow [14], autologous bone particles [15], and autologous bloodderived products (PRF, PRP) [16, 17]. When attempts were made to use autologous bone chips in socket preservation, they failed to promote healing or stimulate hard tissue formation in the socket [15]. The purpose of this article is to present a socket preservation approach using a “one-piece” autologous bone and soft tissue graft harvested from the maxillary tuberosity
