A c c u r a c y o f c o m p u t e r - a s s i s t e d i m p l a n t p l a c e m e n t The main purpose of computer-guided template- assisted surgery is to pre-visualize the approved prosthetic design of the tooth or teeth to be replaced and to relate it to the patient’s available soft and hard tissue. According to a recent study by Vermeulen, in cases of one or more missing teeth in the anterior maxilla, guided surgery yields significantly higher predictability and accuracy than freehand surgery in transferring the virtual implant position to a model situation.3 Therefore, implant position can be optimized according to the esthetic and functional needs and an interim prosthesis can be manufactured prior to the surgical procedure, allowing imme- diate function. Conclusion Within the limitations of the present randomized controlled trial, it was found that intraoral digi- tal impressions may be a viable alternative to conventional impressions and scan models for the rehabilitation of partially edentulous patients using computer-guided template-assisted implant placement. In both groups, the maxi- mum 3-D deviations did not exceed the safe offset of the software. Competing interests The authors declare that they have no compet- ing interests. References 1.
