Abstract

Purpose: The aim of the study was to compare between the accuracy of mucosa-supported stereolithographic surgical guide versus conventional surgical stent in implant supported overdenture. Materials and methods: Twelve patients with completely edentulous patients were selected for this study and divided into three groups. Group (A): 8 implants were placed in the mandible using conventional surgical stents during implant insertion. Group (B): 8 implants were placed in the mandible using partially limiting mucosa-supported stereolithographic (SLA) surgical guide during implant insertion. Group (C): 8 implants were placed in the mandible using completely limiting mucosa-supported stereolithographic (SLA) surgical guide during implant insertion. CBCT was taken following implant insertion to compare between the virtual implant location during the planning and the post insertion implant location in the patients’ mouth to estimate the occurred deviation. Numerical data were explored for normality by checking the distribution of data. All data showed parametric distribution. Data were presented as mean and standard deviation (SD). One-way Analysis of Variance (ANOVA) was used to compare between the three groups. Bonferroni’s post-hoc test was used for pair-wise comparisons when ANOVA test is significant. Results: 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. Conclusion: From the result obtained from this study, it could be concluded that the most accurate surgical guide to be used in implant placement is the completely limiting mucosa-supported stereolithographic surgical guide followed by the partially limiting design then conventional surgical stent was the least accurate in implant placement.
