Correlation between insertion torque and survival rates in immediately loaded implants in the maxilla: a retrospective study.

Objective: To evaluate the correlation between insertion torque and the survival rate of immediately loaded implants placed in the maxilla.

Methods: 390 NobelReplace (Nobel Biocare USA, Yorba Linda, CA) Select Tapered implants were placed in the maxillae of 145 patients over a 15-month period. The insertion torque was measured using a digital torque wrench.
