Summary

objectives

The aim of this study was to assess the implant outcomes as well as hard and soft tissue dimensional changes of immediate implant placement in posterior sites using a custom-made sealing socket abutment (SSA) combined to alveolar ridge preservation (ARP).

Material and methods

Twenty posterior teeth were immediately replaced with implants in 20 patients. The remaining sockets were filled with Deproteinized Bovine Bone Mineral. Based on intra-oral scanners (IOS), custom-made SSAs were placed the same day. CBCT and IOS were performed to monitor hard and soft tissue dimensional changes. Moreover, implant survival rate, peri-implant bone changes, peri-implant health and pink esthetic score were recorded at 1 year, 3years and 5 years.

Conditions

  • Non-maintainable Posterior Tooth (Molars and Premolars)

Interventions

PROCEDURE

Immediate implantation in posterior region with alveolar ridge preservation combined with sealing socket abutment

Twenty BLXⓇ Straumann immediate implants were placed flapless. The gap around the implant was filled with xenogeneic biomaterial. An intra-oral scanner was performed and sent to the dental laboratory to digitally design a customized healing abutment. The abutment was then milled from a block of PEEK and placed a couple of hours later in the clinic. Three months after implantation, the abutment was removed and the final monolithic crown based on the initial IOS was placed. The transmucosal design from the SSA was replicated on the final crown.
