ABSTRACT

Hürzeler presented the socket-shield technique (SST) more than 10 years ago. The partial extraction therapy (PET), a collective concept of utilizing the patient’s own tooth root to preserve the periodontium and peri-implant tissue, has been remarkably developed. PET comprises a group of novel techniques for post-extraction implant placement. Several modifications of PET and simultaneous implant placement have been presented since its inception. Since its origin, several alterations have been employed in the methodology of partial extraction of the root and the simultaneous implant placement. A repeatable, predictable protocol is needed to provide tooth replacement in esthetic dentistry. Moreover, a standardized procedure provides a good framework for clinicians to report data relating to the technique with procedural consistency. This review aims to illustrate a reproducible and systematic protocol for the PET techniques with immediate implant placement at the aesthetic zone. The most used technique is the socket-shield technique, which is potentially offers promising results, minimizing the necessity for invasive bone grafts round implants in the aesthetic area, clinical data to support this is very inadequate. The limited research data existing is cooperated by a deficiency of well-designed prospective randomized controlled investigations. The present case studies and techniques are of actual incomplete technical value. Retrospective studies published in limited records but are of inconsistent plan. At this point, it is indistinct whether the socket-shield technique will offer a stable long-time outcome or not.
