- Brief Summary
1. In cement-retained implant prostheses, the use of a digitally fabricated guide template to form a screw access channel can reduce the angular deviation of the channel and the amount of occlusal surface loss. In particular, the effect of the guide template is significant when the implant tilting degree is large. 2. When using the guide template, the accuracy of the screw channel formation is not affected by implant tilting.
