The impending loss of a single tooth in the anterior
aesthetic zone can be a traumatic experience. Although single-tooth restoration
with osseointegrated implants has been well-documented, successful placement of
an anterior single implant may be complicated based on its position and
surrounding tissue support. Numerous authors have demonstrated the significance
of the underlying osseous structures to the ultimate location of the gingival
tissue. Dentogingival dimensions of 3 mm facially of the failing tooth and 4.5
mm interproximally of the adjacent teeth must be established and the osseous
architecture must be preserved for predictable implant aesthetics.
Nevertheless, tissue stability of the anticipated implant restoration is
dependent upon the periodontal form of the prospective implant site. Since
gingival and interproximal papillary recession is difficult to regain, osseous
structures must be preserved to ensure maintenance of the gingival
architecture. If the failing tooth possesses a gingival architecture with
proper underlying bony support that harmonizes with the surrounding dentition,
these structures must be maintained using the appropriate surgical and
prosthodontic techniques at the time of tooth extraction.
