Analysis of the precision of implant templates

Maximum deviations of 2.0 mm in the horizontal dimension and 1.0 mm in the vertical dimension were found. Much smaller deviations with more precise positions were found with the ExpertEase version compared with the Med3D-assisted procedure.

In our comparisons, there were no noteworthy differences in drilling precision between an experienced implantologist and a dental nurse without any practical experience on patients. With observation of the basic principles of implantology and use of planning software with template-guided surgery, exact implant placement to within less than a millimeter is possible, even in the most demanding situations.

Conclusion

The holes drilled with a 3 mm diameter twist drill show a high degree of precision, which could probably not have been obtained by free-hand drilling. The “sleeves on drill” technique, using drills with depth stops specially made for navigated implantology appears to confer advantages compared with “normal” drills guided through ordinary sleeves.
