Objective:The oral implant templates was fabricated with CT、three-dimensional laser scanning and computer aided design/computer aided manufacture(CAD/CAM),and it was to compare the accuracy of template. Method:All patients accepted CT scanning,the date were imported in SimPlant software to reconstruct three-dimensional model and simulate implantation.The dental models were scanned by three- dimensional laser scanning machine.The CT scanning data of each patient and 3D laser scanning data of dentition plaster model matched with Geomagic software.According to the planed implants position and digitized plaster model,we design the guiding template in Geomagic software.Finally the surgical template were fabricated by rapid prototyping.In total, 45 implants were inserted. Measurements deviation between planned implants and actual implants after the registration of pre- and post-operative CT images. Result:The entry deviations of the implant was(0.85±0.19)mm and apical deviation was(0.97±0.21)mm and the axis deviation was(4.53±1.89)°. Conclusion: The template which fabricated by comprehensive utilization of three-dimentional laser scanning technique,SimPlant simulation and rapid prototyping are well guided implant surgery,and it provides a reliable guarantee for improving the success rate of implanting.
