Abstract

Accurately recording the deficiency of the three-dimensional position of dental implants and the predetermined occlusal relationship of edentulous jaws presents a significant challenge. This study aimed to achieve a truly digital workflow of immediate full-arch implant restoration by combinedcone-beam computed tomography (CBCT), photogrammetry (PG) devices, and intraoral scanners (IOS). This approach significantly reduces patient tooth loss time, minimizes the overall “chair time”, and provides precise, comfortable, and efficient implant restoration treatment. A total of 11 edentulous patients (mean age 64.72 ± 9.83 years) were treated, and outcomes such as implant survival, prosthesis survival rates, marginal bone resorption, and incidences of complications were evaluated. The results demonstrated that immediate full-arch rehabilitation of edentulous jaws on 4 or 6 implants using a PG system is an effective, safe, and efficient approach to rehabilitation.
