Abstract

Purpose: To assess patients’ satisfaction and aesthetic outcomes of single implant restorations in aesthetic zone using superimposition of intraoral scan (IOS) and CBCT. Subjects and Methods: 14 patients with a single tooth loss in upper aesthetic zone indicated for implants, were divided into 2 equal groups. Group (1): Implant planning without superimposition. Group (2): Implant planning using superimposition. Implant drilling for both groups was performed through a flapless surgical technique. In group (1), the surgical template was fabricated on a diagnostic model and used only during drilling of the point of entry of implant. In group (2), IOS and CBCT were imported into RealGUIDE software for superimposition, virtual implant planning, and surgical guide designing. For precisely guided implant surgery, a surgical guide that was 3D printed was utilized. All patients received screw-retained customized zirconia abutments/crowns. Using a subjective outcome questionnaire, patients were asked to score their satisfaction with the overall implant treatment. The Pink Esthetic Score, Implant Crown Esthetic Index, White Esthetic Score, and Peri-Implant and Crown Index were used to assess the soft tissue that surrounds the implant supported crown. Results: There was insignificant difference between the groups in terms of patient satisfaction. Regarding different aesthetic scores, group (2) showed better mean values than group (1) at both intervals, however, the difference was insignificant. The PES index revealed a significant increase from T0 to T3 in both groups. Conclusions: Superimposition of IOS and CBCT does not significantly affect patients’ satisfaction and aesthetic outcomes of single implant restoration in aesthetic zone.
