The "Dual-Zone" Approach in Immediate Implant Placement
Dennis P. Tarnow, DDS;Stephen J. Chu, DMD, MSD, CDT
Improvements in implant designs have helped advance successful immediate anterior implant placement into fresh extraction sockets. Clinical techniques described have enabled practitioners to achieve predictable esthetic success using a method that limits the amount of buccal contour change of the extraction site ridge and potentially enhances the thickness of the peri-implant soft tissues coronal to the implant-abutment interface. This approach involves atraumatic tooth removal without flap elevation, and placing a bone graft into the residual gap around an immediate fresh-socket anterior implant with a screw-retained provisional restoration acting as a prosthetic socket seal device. This protocol allows for efficient management of the patient and an attempt to maintain all original contours of the extraction site. Multiple case and retrospective case studies will be cited to support this concept.
