Immediate Placement and Temporization of Implants: Three- to Five-year Retrospective Results
The immediate placement of dental implants in esthetic areas is a primary challenge for modern implantology. The underlying treatment goal is to preserve the natural periodontal architecture; in recent years, however, a concurrent goal has been to reduce the period between implant placement in the fresh extraction socket and delivery of the definitive restoration, but adequate long-term data are still lacking on the efficacy of this technique. A 3- to 5-year retrospective analysis of 282 dental implants immediately placed into extraction sockets, and temporized with nonoccluding provisional prostheses has been undertaken. All recorded outcomes and complications, as well as a proposed protocol for management of immediate function, are discussed.Abstract

(a) Nonsalvageable lateral upper incisor. (b) X-ray showing reconstruction and infection at apex. (c) Extraction performed with maximum respect for soft tissues and bone. A one-piece, one-stage, screw-type implant is placed. (d) A provisional crown has been delivered to the abutment. The entire zone has been washed.

(a) Fractured maxillary lateral incisor. Conventional treatment was rejected. (b) Extraction and placement of a two-piece, one-stage, screw-type transgingival implant. (c) A conic abutment shorter than usual has been attached to the implant. (d) A provisional crown was delivered with no occluding contact.

(a) Unsalvageable lateral incisor root. (b) Soft and hard tissues remained intact during extraction. (c) Palatal placement of a two-piece, one-stage, screw-type transgingival implant. (d) Provisional crown in place.
