  1. Normal group: periodontal mechanosensitive threshold is ≤5 g. High group: periodontal mechanosensitive threshold is ≥5.1 g in implant-adjacent premolars. Small contact group: implant occlusal contact area is less than half that of adjacent premolars. Large contact group: implant occlusal contact area is at least half that of adjacent premolars. Categorical data were examined using the Chi square test and continuous data were examined using the Mann–Whitney U test
