Application of prefabricated restoration made by the combination of surgical guide and guided cylinder with pin

Objective To investigate the feasibility of prefabricated restoration made by the combination of digital surgical guide and guided cylinder with pin(GCP) in immediate implant restoration. Methods Six patients requiring immediate repair were selected. Before the surgery, NobelClinician software was used to design and manufacture digital surgical guides.Plaster models were copy and made followed the GCP and surgical guides and then provisional restorations were made on the plaster model. Surgeries were performed on an elective basis and immediate restoration was performed after surgery. On the day of immediate restoration, CBCT was taken again to compare the deviation between the preoperative software design and the actual implant position. The placement of temporary prosthesis and the satisfaction of patients were evaluated.Permanent repair was performed after 4-6 months of healing.The reverse software was used to analyze the three-dimensional deviation between the preoperative design and the actual implanted implant in 3 cases. Results The overall comparison showed that the direction and angle of the actual implant site were basically consistent with the preoperative design site. A total of 20 teeth were counted in 3 patients,the average deviation of buccolingual direction was less than 0.3 mm, mesial distal deviation was less than 0.2 mm, and depth deviation was less than 0.3 mm. The patients were successfully put into the temporary restoration after the operation, and the expected effect was achieved. One patient was basically satisfied (16.7%) and five patients were very satisfied ( 83.3%).Conclusion It is feasible to prepare temporary prosthetic techniques for immediate repair afterimplantation.Prefabricated restoration provides a reference for real-time immediate restoration. The three-dimensional position of the actual implant is deviated from the design but is within acceptable limits.
