Summary

One of the major challenges one clinician can face while performing immediate placement on posterior area, is the ability of obtaining a hermetic primary closure of the soft tissue. The use of socket sealing abutment may provide advantages in maintaining the existing soft tissue architecture, preserving crestal bone height and reducing the risk of premature loading of the immediate implant during healing

Detailed description

One of the major challenges one clinician can face while performing immediate placement on posterior area, is the ability of obtaining a hermetic primary closure of the soft tissue. This technical skill is nearly always combined with invasive surgical procedures and significant post op recovery (displacement of the muco-gingival line, periosteal releasing incision, flaps, sutures, membrane stabilization, …).the use of customized healing abutment may provide advantages in maintaining the existing soft tissue architecture, preserving crestal bone height and reducing the risk of premature loading of the immediate implant during healing. Moreover, customized healing abutment can passively accommodate the definitive prosthesis with minimal or no pressure placement preventing biological or mechanical trauma during the prosthetic phases. This may lead to better long-term tissue stability and avoid the pain perceived by the patients from compression of tissues in case of standard healing abutment. the primary aim of this randomized controlled clinical study is to clinically evaluate and compare the soft tissue outcomes of final immediate implant restorations placed in maxillary posterior sites that were conditioned by CAD/CAM fabricated socket sealing abutments versus standard healing abutments. The secondary aim of this study is to radiographically assess peri-implant bone level changes of the final immediate implant restorations placed in maxillary posterior sites for the two experimental groups.

Conditions

• Implant Site Reaction

Interventions

Type	Name	Description
PROCEDURE	cad/cam socket sealing abutment	Anatomically formed healing abutments that can solve many of the problems inherent to immediate posterior implant placement and to optimize the conditioning of supra implant tissue architecture enhancing the emergence profile of the final implant restoration
PROCEDURE	standard healing abutment	Standard healing abutment will be inserted after removal of cover screw after immediate implant insertion and then a muco-periosteal flap will be reflected for the primary closure of the socket and sutured around the standard healing abutment.
