48 Chapter 3 ation, which is the angle between the longitudinal axes of the planned and placed implant; lateral deviation, which is the distance between the intersection of the plane perpendicular to the planned implant shoulder with the longitudinal axis of the placed implant (point C) and the coronal centre of the planned implant (point A); and depth deviation, which is the distance between the coronal centre of the planned implant (point A) and the centre point of a plane parallel to the plane perpendicular to the planned implant shoulder (point D), which intersects through the coronal centre of the placed implant (point B). The deviations between the planned and placed implants were measured in 3Matic Medical 11.0. The results were presented as descriptive statistics (Table 3.1).
