Trueness of Dental Implant Placement Using Dynamic Navigation or Non-Guided Approach by Novice Surgeons: A...

To compare the trueness of implant placement in novice surgeons using dynamic computer-assisted implant surgery (d-CAIS) versus a non-guided approach, assessing surgery time efficiency and patient-reported outcomes, including satisfaction, postoperative pain, and quality of life.

A double-arm randomized clinical trial was conducted. Consecutive partially edentulous patients were randomly assigned to d-CAIS or non-guided. Trueness outcomes, including apex and platform linear deviation (mm) and angular deviation (degrees), were measured by superimposing pre- and postoperative CBCT scans. Pre- and postoperative questionnaires assessed patient self-reported satisfaction and quality of life during surgery and in the postoperative period.

Sixty patients (72 implants) were included. Thirty patients received 36 implants using d-CAIS, while another 30 patients received 36 implants with the non-guided technique. d-CAIS significantly reduced angular (MD: -5.51°; p < 0.001), lateral platform (MD: -0.79 mm; p = 0.037), global platform (MD: -0.89 mm; p = 0.024), and global apex deviations (MD: -1.23 mm; p = 0.001). Although the implant placement time was significantly shorter with d-CAIS (p = 0.022), there was no statistically significant difference in overall surgery time between the groups (MD: -6.18 min; p = 0.190). Postoperative pain and analgesic consumption were similar, with high self-reported satisfaction. The surgical procedure did not result in significant changes in patient quality of life.

Implant placement using d-CAIS by novice surgeons shows higher trueness, without increasing surgery time. It also ensures high patient satisfaction and quality of life, with pain levels comparable to those of the non-guided technique.
