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

Table 4

Mean and standard deviations of absolute errors for the distance of the implant from the mental foramen (right and left) and the anterior loop of the inferior alveolar nerve (right and left) at different angulations of the mandible and in three different voxel sizes (a: voxel  mm, b: voxel  mm, and c: voxel  mm).

Location/angulation	(mm) (right ^∗AL)	(mm) (left ^∗AL)	(mm) (right ^∗MF)	(mm) (left ^∗MF)

MAE: mean absolute error; SD: standard deviation. AL: anterior loop; MF: mental foramen.
