[Short-term follow up of treatment effect using one-time one-abutment placement in implant restoration in 35 patients with single posterior teeth loss].

PURPOSE: To evaluate the effet of one-time one-abutment placement on peri-implant tissues.

METHODS

Thirty-five patients with single posterior loss were collected, who received definitive abutment at the moment of implant placement. One day and after 1 year of implant loading, radiographic assessment of marginal bone level changes and clinical status of peri-implant soft tissues were conducted. Plaque index, pocket depth as well as sulcus bleeding index were assessed.

RESULTS

During 1 year follow-up period after loading, no implant failure was observed. The mean marginal bone loss of implants were (0.225±0.113) mm mesially and (0.439±0.123) mm distally. Standard periodontal probes were used to measure plaque index, probing depth, and gingival crevicular bleeding index immediately after repair and 1 year later.

CONCLUSIONS

In the posterior region, one-time one-abutment placement may better protect peri-implant tissues as an ideal treatment protocol.
