Surgical Extraction of an Impacted Canine and Immediate Implant Placement: A Prosthetically Guided Digital Approach

This is a prospective study, in which there are involved four clinical cases of surgical extraction of impacted maxillary canines followed by immediate implant placement and immediate screw-retained temporary crown using a full-digital workflow that included performing a CBCT, an intraoral scan, AI-assisted segmentation, a virtual wax-up, and the design of a surgical guide and a 30° angled abutment. Then, the follow-up lasting two years is performed to verify the functional and esthetical outcomes. The patients included in this report are part of an ongoing clinical trial, and the complete data set will be published separately upon study completion. The aims is to present clinical outcomes and synthesize evidence comparing placing implant to avoid buccal augmentation using angles abutments versus performing guided bone regeneration (GBR) to allow ideal implant placement with straight abutments, and to evaluate the risk of abutment screw loosening.
