A Method for Improving Dental Crown Fit-Increasing the Robustness
The introduction of mass-customization has enabled
new ways to treat patients within medicine. However, the
introduction of industrialized treatments has also meant new
obstacles. The purpose of this study was to introduce and
theoretically test a method for improving dental crown fit. The
optimization method allocates support points in order to check the
final variation for dental crowns. Three different types of geometries
were tested and compared. The three geometries were also divided
into three sub-geometries: Current method, Optimized method and
Feasible method. The Optimized method, using the whole surface for
support points, provided the best results. The results support the
objective of the study. It also seems that the support optimization
method can dramatically improve the robustness of dental crown
treatments.
