Accuracy and Reproducibility of Virtually Guided Minimally Invasive Tooth Preparations Using Reverse Engineering

NCT04653519 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 10

No results posted yet for this study

Summary

The aim of the study is to assess and reproduce standardized virtually guided minimally invasive tooth preparations using digitally designed occlusal template, compared to its reference virtual preparation using a computer aided 3-dimensional (3-D) analysis, and to investigate the effect of these preparations on absolute marginal discrepancy of 3 unit monolithic translucent zirconia FPD using a computer aided 3-D analysis.

Conditions

  • Marginal Adaptation of Fixed Dental Prosthesis

Interventions

DEVICE

Virtually guided minimally invasive preparation

Intraoral virtually guided minimally invasive design with an occlusal reduction of 1.5mm, axial reduction will be performed with 6 degrees axial taper and a circumferential chamfer margin of 0.5mm in width and 0.5mm coronal to the gingival margin. A milled guiding occlusal resin template of the teeth will be checked for fitting then fixed using spot etching and will be used to guide the amount of axial reductions and taper degree.
