Background

Endodontic treatment is designed to prevent and/or resolve pulpal and periapical pathological conditions, thereby reestablishing healthy periradicular tissues. Long-term survival is high with nonsurgical root canal treatment (NSRCT), but healing does not always follow this intervention. Successfully treated teeth can become reinfected through coronal microleakage as well. Implant-supported single crowns (ISCs) are an option for these cases that has a high success rate. In addition, apical

Methods

The PubMed, Cochrane Library, Web of Science, and Embase databases were searched for publications from January 1966 to April 2014. Articles were divided into those on ISC and those on IR.

Results

There were 27 articles on ISC included in the analysis, representing 838 teeth and 4130 implants. Sample sizes ranged from 20 to 287 teeth. Follow-up varied from 2 to 6+ years, but most ISC losses occurred in the first 2 years after the procedure. Significant variance in survival was noted between the studies.

Eight studies addressed IR, with follow-up ranging from 2 to 22 years. Most IR losses occurred in the first 2 years, with rates stabilizing thereafter. Only two of the IR studies were

Discussion

The survival for ISCs was significantly greater than for IR teeth. IR is not often performed, being considered an option of last resort by many. When it is done, the second maxillary and mandibular molars are the most common candidates. It may be a more cost-effective option, however, with its initial cost similar to that for apical surgery. Interestingly, the larger the sample size, the lower the prevalence of resorption in IR teeth. Performance may be improved by experience and repetition.
