Single-unit implants versus conventional treatments for compromised teeth: a brief review of the evidence.

The goal of preserving the natural dentition has long provided the foundation for clinical decision making in dentistry. Current trends in implant dentistry have weakened this paradigm as many practitioners have moved quickly to adopt implant dentistry as a new standard of care; however, the rapidity of this shift is a cause for concern among others. Many short-term studies have reported favorable data supporting the growth of single-unit implant dentistry, but the lack of standardized outcome evaluations and broadly conceived dimensions of performance makes it difficult to compare these reports. Thus, even with the exciting new treatment options implant dentistry offers patients and practitioners, all due consideration should first be given to treatments aimed at preserving and restoring compromised teeth before pursuing extraction and replacement. This article examines this premise from five perspectives: form, function, survival, management of complications, and quality of life.
