Abstract
Introduction
Currently, there are no studies evaluating the impact of 3-dimensional (3D) printed
models on endodontic surgical treatment planning. The aims of this study were: 1)
to determine if 3D models could influence treatment planning; and 2) to assess the
effect of 3D supported planning on operator confidence.
Materials
Endodontic practitioners (n = 25) were asked to analyze a preselected cone beam computed tomography (CBCT) scan
of an endodontic surgical case and answer a questionnaire that elucidated their surgical
approach. After 30 days, the same participants were asked to analyze the same CBCT
scan. Additionally, participants were asked to study and to perform a mock osteotomy
on a 3D printed model. The participants responded to the same questionnaire along
with a new set of questions. Responses were statistically analyzed using chi square
test followed by either logistic or ordered regression analysis. Adjustment for multiple
comparison analysis was done using a Bonferroni correction. Statistical significance
was set at ≤0.005.
Results
The availability of both the 3D printed model and the CBCT scan resulted in statistically
significant differences in the participants' responses to their ability to detect
bone landmarks, predict the location of osteotomy, and to determine the following:
size of osteotomy, angle of instrumentation, involvement of critical structures in
flap reflection and involvement of vital structures during curettage. In addition,
the participants’ confidence in performing surgery was found to be significantly higher.
Conclusions
The availability of 3D printed models did not alter the participants’ surgical approach
but it significantly improved their confidence for endodontic microsurgery.
