Detailed description

Objectives: The aim of this randomized control trial was to compare immediate restoration procedure with a one abutment one-time technique using a conventional versus full digital workflow. Surgical accuracy, provisional fit and patient reported outcome measures (PROMs) of. Material and method: Sites with single edentulous spaces and neighboring natural teeth were randomized into static computer-aided implant surgery (s-CAIS) or freehand placement implant surgery groups. In both groups, digital implant planning was performed using data from cone beam computed tomography (CBCT) and surfaces scans. In the s-CAIS group, a surgical guide was produced and used for fully guided implant surgery, while in the freehand group, the implants were placed in a freehand manner. the deviations in angles, shoulders and apexes between planned and actual implant positions were measured based on postoperative optic impressions. In the test group, a custom-made zirconia abutment and a provisional restoration were immediately placed using a full digital workflow whereas in the control group, a physical impression was taken, and the abutment and crown were placed 10 days post-surgery. Loading outcomes (interproximal contact, occlusal contact, white esthetic score (WES)) were assessed as the PROMs.
