| Abstract | ||
| Aim: The aim of this study was to compare the accuracy of implant placement when using tooth supported surgical guide versus tooth tissue supported one manufactured by DLP (Digital Light Processing) technique. Methodology: 21replica implants were inserted in 7 partially edentulous maxillary resin cast. Surgical implant placement was done using static DLP printed surgical guides, Three designs of surgical guides were designed representing different type and position of support (Anterior tooth-supported, Posterior tooth-supported and posterior tooth-tissue supported) respectively when using the same number of tooth support. . After implant placement Accuracy measurements were done using (blue sky bio software) by superimposing the actually placed implants with the virtually planned implants. Results : Regarding mesiodistal and buccolingual distance, lack of statistical significant difference was found between both group 1 and 2 while both show stistical significant difference in compare with (tooth tissue supported ones ) . Regarding the depth results. Post tooth supported guides show a statistical significant difference over both group 1 and group 3 While the ant tooth supported guide was in statistical significant with tooth tissue supported one. Conclusion: using 3 units of posterior tooth supported guides offer accurate implant positioning. on the other hand, using Three units anterior tooth supported surgical guides have shown less yet still satisfactory results of accuracy when compared to posterior tooth supported ones , using3 units of tooth tissue supported guides results in higher significant deviation value thus it was risky to be used even In single implant placement. | ||
