Masticatory function following implants replacing a second molar

The aim of this study was to obtain objective and standardized information on masticatory function and patient satisfaction following second molar single implant therapy. Twenty adult patients, who had restored second molar single implants more than 1 month before the study, were enrolled in this study. All patients received a chewing test using peanuts before and after insertion of the implant prosthesis, with a questionnaire and visual analogue scale (VAS) to evaluate the effect of second molar single implant therapy. This study obtained standardized information on the masticatory function objectively (e.g., P, R, X(50)) before (Pre-insertion) and after insertion (Post-insertion) of the implant prosthesis. Masticatory performance (P) after insertion of the implant prosthesis significantly increased from 67.8±9.9 to 84.3±8.5% (P
