Abstract:

Immediate loading with provisional prostheses in edentulous patients enables full-arch functional restoration through the placement of 4 to 8 implants, significantly reducing the duration of tooth loss. This technique includes two main methods: postoperative intraoral impression-taking and preoperatively fabricated prostheses. The traditional splinted open-tray impression technique offers high accuracy but involves complex procedures, whereas digital impressions combined with stereophotogrammetry have improved both efficiency and patient comfort. The preoperative fabrication method relies on digital planning and a pick-up technique, which helps minimize intraoperative errors but requires strict adherence to preoperative data. The choice of technique should be individualized based on the patient’s anatomical conditions, occlusal stability, and available equipment. Digital workflows further enhance the precision and mechanical strength of the prostheses. Based on clinical experience, this review discusses key aspects of immediate provisional restoration in edentulous cases. Clinicians should maintain critical judgment when applying these techniques and select the most appropriate surgical and restorative methods according to each specific situation.
