简要总结
The aim of this clinical study is to evaluate the accuracy of placing pterygoid implants using custom-made surgical guides in patients with atrophied posterior maxilla. The study focuses on measuring how closely the actual implant position matches the virtual preoperative plan in terms of angle and distance.
详细描述
Rehabilitation of the atrophic posterior maxilla remains a surgical challenge. This study utilizes pterygoid implants as a graftless solution. For each participant, a digital workflow is followed: a cone-beam computed tomography (CBCT) scan and an intraoral scan are performed to design a custom-made surgical guide. Following implant placement, a postoperative CBCT is obtained. The accuracy is then evaluated by superimposing the planned and actual implant positions to calculate the coronal, apical, and angular deviations.
