Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Five stryofoam mandibles were included in this study to assess the accuracy of using computer guided surgical stent in placement of dental implants. The mandibles were CBCT scanned and imported to 3diagnosys software to implant planning. 8 implants were placed in each mandible virtually, 4 anterior implants and 4 posterior implants were placed. The plan was exported as STL file to be imported to the CAD software for designing of the stent. The surgical stent is printed using Micro DGP printer and invision tec e-shell 600 clear resin was used. Stainless steel sleeves were placed in the surgical guide then placed in ethanol 99% to remove the excess monomer.

The stent in placed over the mandible and sequential drilling was done until the desired osteotomies width was approached followed by the placement of the implants. Post-operative CBCT was done for the mandible including the implants to assess the accuracy, angulation and position of the placed implants

CBCT Scanning

The Styrofoam mandibles were scanned using CBCT, which was performed for each mandible pre-operatively, the raw DICOM data set obtained from the CBCT scanning were imported to a special third-party software\* for secondary reconstruction.
