Title Success Rate of Single Molar Implants is Similar to Root Resections in Patient with Furcated Molars
Clinical Question In patients with furcated molars, does tooth extraction and single molar implant placement compared to root resection lead to better success rate?
Clinical Bottom Line Molar implant placement and root resection demonstrated similarly high success rates when used as treatment options in furcated molars. Importantly, the overall success rate for both treatments was found to be approximately 97% after 1-15 years in function.

Key resultsRoot resected molars showed success rate of 96.8% while molar implants had 97% success rate. Importantly, resection of the distal root of a mandibular molar demonstrated the lowest success rate among all root resection categories (75%). There was a trend towards higher failure rates when both treatments were performed in teeth that were the last in the arch.

The Evidence
Validity: This is a well-designed retrospective analysis with a large sample size and a long-term follow-up. The results of this study are based on patients from one private practice, however it is not mentioned whether the same clinician performed all cases. The author underlined the possibility of unreported failures that were not included in the study, as the patients were not longer seen in this practice. Perspective: Although the case series does not display strong evidence such as being a randomized control trial or systematic review, it is the most current evidence and only research on this topic. Randomized clinical trials are needed to validate the results of this study.
Applicability Root resection surgeries require endodontic and prosthetic treatment whereas dental implants may demand bone augmentation therapies. Therefore, both treatments require several stages to complete. Financial abilities of patients to afford each type of treatment must be considered when treatment planning. Consequently, the final decision of choosing whether root resection or dental implant is a case-by-case basis, made in congruent with the overall treatment plan, and collectively decided with the patients. Ultimately, success rate and longevity of the treatment heavily depend on the importance of oral hygiene and periodontal health of dentition.
