Abstract
Purpose: The goal of this study was to evaluate the clinical outcome and performance of short implants placed in mandibular posterior area.
Materials and Methods: A total of 17 single short implants were placed in the posterior and supported single restoration. Primary stability immediately after the placement of implant was measured using Osstellⓡ Mentor (Osstell, Sweden), and secondary stability after second surgery or during impression. For compensating radiographic image distortion, Marginal bone loss was calculated the ratio of actual implant fixture length to that of image.
Results: Mean follow-up period was 41.7 months. The average ISQ value increased from 63.50±22.89 to 75.17±16.59, with statistical significance (P＜0.05). 1 osseointegration failure at 4.67 months after loading was found. An average marginal bone loss around implants of 0.014 mm, 0.025 mm, and 0.319 mm at 12 months, 24 months, and final follow up after functional loading. The survival rate was 94.1±0.24% in average 41.70 months.
Conclusions: With careful case selections, short-length implants may offer a predictable treatment alternative in load-bearing posterior sites where unfavorable anatomical conditions may exist.
