Surgical Guide Preparation from Computed Tomography Data for Placement of Dental Implants

SUMMARY AND CONCLUSION: The conclusions drawn from this study conducted to simulate the virtual implant placement with computed tomography data using implant simulation software (IMPLANT 3D) and to construct a surgical guide with progressively diameter sleeves to accurately place implants, were that extensive pre operative planning and accurate execution of the plan is crucial for precise placement of implants which is necessary for long term treatment success. Imaging tools, implant planning software, precise surgical guide, good understanding of anatomy, surgical principles and post operative care are essential. Students paired-t test was done to compare the variables (Pan angle & Sect. angle) between pre operative and post operative positions of all the implants. No statistically significant difference were found between pre and post operative conditions which concludes that the surgical guide with progressive 316L stainless steel sleeves helped in accurate transfer of virtual implant position. This method of treatment planning may not be necessary in simpler cases, as much planning is not required in cases having good ridge with adequate bone height and width. Conventional technique may be used in such cases as cost of treatment will be reduced
