OBJECTIVES: Interest in the Root Membrane Technique (RMT) using the remaining root, which can preserve the buccal bone by placing the implant around the remaining root, has recently increased.

METHODS: This study aimed to assess the safety and effectiveness of the RMT in patients who require implant as part of the nHTA. The safety and effectiveness of the technique were assessed via a systematic review.

RESULTS: The safety and effectiveness of the technique were assessed based on 9 studies(8 RCTs, 1 cohort study). For safety, 5 studies reported no side effects and adverse reactions, and in 2 studies, internal shield exposure (n=2) and internal and external shield exposure (n=1) of the intervention group were reported. There were no implant failures in 4 studies, and only 1 study reported 1 failure in both groups. Regarding efficacy, the height of the bone plate was significantly lower in the intervention group than in the control group in 2 trials. The difference in bone plate thickness between groups during the final follow-up period was low in the intervention group at all time points of follow-up. Regarding changes in bone level around the implant, in three studies, the intervention group had a lower loss value than the control group, and there was a statistically significant difference between the groups. Aesthetic results were reported through the Pink Esthetic Score in a total of 7 articles. In 4 cases, the intervention group was higher than the control group, and it was statistically significant. In the other three, the difference was not statistically significant.

CONCLUSIONS: The nHTA committee concluded that the technology is effective, but for safety, more well-designed studies with long-term follow-up (1–5 years) are needed as potential long-term physiological adverse events and complications that occur due to root resorption must be examined (level of evidence A, technology category II-a).
