The accuracy of implant placement using a combination of static and dynamic computer‐assisted implant surgery in fully edentulous arches: A prospective controlled clinical study

Objective To compare the accuracy of implant position, using a combination of static and dynamic computer‐assisted implant surgery (CAIS), with either static, dynamic, or freehand implant placement, in fully edentulous arches. Materials and Methods Twenty‐one patients with a total of 88 fixtures were included. Implants were divided equally into four groups: a combination of static and dynamic CAIS (SD group), static CAIS (S group), dynamic CAIS (D group), and freehand placement (FH group). Angular deviation, as well as the 3D platform and apex deviations, were measured for all groups. Furthermore, the direction of implant deviation was recorded and compared. Results The FH group showed significantly more deviation compared to all groups, considering all the aspects, and at both the implant platform and apex. A significant difference in angular deviation between the SD and S groups (p
