| Abstract | ||||
| Purpose: This clinical trial aimed to compare the effect of direct functional pick-up versus digital indirect pick-up techniques for implant overdenture attachments on peri-implant soft tissue health and alveolar bone height. Methods: Thirty completely edentulous patients were selected in this study, each patient received two mandibular implants in the canine regions. Ball and socket attachments were screwed to implants after osseointegration. According to technique of construction of definitive complete overdenture and pick-up all cases were randomly divided into two groups: conventional group (n = 15): obtained conventional denture base with direct pickup technique and 3D-milled group (n = 15): obtained CAD/CAM milled denture base with digital (indirect) pickup technique. Peri-implant bone loss and soft tissue changes were measured during the first six month (T1) and second six month 6 months (T2) and entire year (T3) after insertion. Results: there was insignificant difference between the two groups at T1 (P=0.843), T2 (P=0.856), and T3 (P=0.916) Regarding peri-implant alveolar bone loss, However, significant differences were observed over time in both groups. Regarding Peri-implant probing depth, there was insignificant difference between groups at T0 (P=0.615), T6 (P=0.426), and T12 (P=0.881), However significant differences occurred over time in both groups (P<0.001). Conclusion: The digital indirect pick-up technique for implant overdenture attachment in milled denture bases can be regarded as a precise approach when compared to direct functional pick-up in conventional denture regarding peri-implant bone loss and probing depth. | ||||
