Due to high bone density, a 4.5 mm drill has to be used in order to place a 5x7.3 mm definitive implant (Fig.3). In spite of the fact that the implant seems to be completely seated, the implant is ~ 1 mm supracrestal lingually. An accessory canal (yellow line) branches off the Inferior Alveolar Canal (red line). It is associated with intraop pain.
