Prospective study of treatment outcome of implant retained mandibular overdenture: Two years follow-up

The aim of this study is to evaluate the treatment outcome of immediately loaded Implants in the interforaminal region of anterior mandible. A total of 15 completely edentulous patients aged between 50 and 70 years were selected satisfying certain inclusion and exclusion criteria. Two implants were placed in 33 and 43 region (B and D location) and the implants were loaded immediately by mandibular overdenture retained with O-ring attachments. The implants were evaluated for various clinical parameters at 6 months, 1 year, 1.5 years, and 2 years intervals after initial placement. There was increased marginal bone loss around implants during the 1(st) year after that the bone loss was insignificant. Clinical stability of immediately loaded implants was lower initially for 6 months, but improved by the end of 1(st) year. Survival rate for immediately loaded implants was 96.6% at the end of the period of study. Immediate loading of interforaminal mandibular implants demonstrated a highly acceptable clinical success at the end of 2 years. However, initially the marginal bone level and clinical stability were significantly lower which showed improvement with time.
