Evaluation of Accuracy of Three-Dimensionally Guided Zygomatic Implant Installation

Plain-language summary

This study was conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University. A prospective non-controlled clinical study was performed on ten patients with compromised zygomaticomaxillary bone. Surgical intervention was carried out using a customized surgical guide. Pre-surgical planning was performed using computed tomography (CT) scans for each patient. Surgical guides were fabricated using direct metal laser sintering technology. Zygomatic implants were inserted using a guided surgical protocol and specialized instruments. Postoperative CT scans were obtained to evaluate deviations between the planned and actual implant positions. Accuracy was assessed by superimposing the postoperative implant position onto the virtual pre-surgical implant plan using dedicated software. Descriptive and bivariate statistical analyses were performed.
