The Effect of Mandibular Angulation on Preoperative Assessment of Dental Implant Insertion at Premolar Region: CBCT Study

Table 3

Pairwise comparison between the distance of implant from mental foramen (right and left) and anterior loop of the inferior alveolar nerve (right and left) at different angulations of the mandible in similar resolutions (a: voxel  mm, b: voxel  mm, and c: voxel  mm).
