Title Replacing Missing Molars with Removable Prostheses Does Not Reduce or Prevent TMD Pain
Clinical Question In a patient with bilateral molar loss in either maxillary and/or mandibular arches, would replacing the missing molars with removable prostheses, reduce or prevent TMD pain compared to no treatment?
Clinical Bottom Line Over 5-year follow-up, TMD pain was statistically similar in patients who had bilateral missing molars replaced or not replaced with removable prostheses.

Key resultsReissmann et al found that the mean TMD pain intensity was identical between the group replacing and the group not replacing the missing molars. Over 5-year follow-up, there was no significant difference between the two groups, suggesting that molar replacement with a removable prosthesis is not a viable treatment for reducing TMD pain.

Comments on
The Evidence
The study by Reismann et al was a randomized controlled trial including 152 subjects, which indicates a high level of evidence. However, it should be noted that 63 subjects were excluded following randomization due to preference of an alternate solution or high costs. Furthermore, the mean TMD pain intensity was almost statistically equivalent between the group who had their missing molars replaced compared to the group who did not have their missing molars replaced.
Applicability For bilaterally edentulous patients who only occlude on posterior premolars, molar replacement using a removable prosthesis is equally effective as no treatment in reducing or preventing TMD pain. This information would be integral during treatment planning for a patient with missing molars, as a removable prosthesis should not be expected to reduce or prevent the patient's TMD pain. Additionally, the study is limited to molar replacement by a removable prosthesis and the results cannot be generalized to molar replacement by implant-supported prostheses.
