Abstract
The accuracy of mucosa-supported stereolithographic surgical guide and the conventional surgical stent in implant supported overdenture was evaluated in this study. Completely edentulous patients were selected free from any systemic or local diseases that may affect the results of this study.
Selected patients were randomly divided into three groups, group A, patients received 8 implants in the mandible using conventional surgical stents during implant insertion. group B, patients received 8 implants using partially limiting mucosa-supported stereolithographic (SLA) surgical guide during implant insertion. group C, patients received 8 implants using completely limiting mucosa-supported stereolithographic (SLA) surgical guide during implant insertion.
The accuracy of the surgical guides were evaluated using CBCT machine by evaluating the deviation between the planned (virtual) implant and the placed (actual) implant. The preoperative CBCT with the planned implant sites and the post-operative CBCT were aligned together for the automatic superimposition by On3Demand software until finding the best overlap of the two images, then the comparison was done automatically.
It was found that group C of the patients that used the completely limiting surgical guide was the most accurate one with little deviation in implant placement, Followed by group B of the patients that used the partially limiting surgical guide then the least accurate was for group A of the patients that used the conventional stent.
