Abstract:
Objective: To realize the requirement of adjacent area accuracy,axial surface physical contour and smoothness in the process of inlay computer-aided design(CAD).Methods:A compromised method was brought forward that some assistant 3-D constraint lines from occlusion to gingiva were used to lead the inlay contour on axial corner and other characterized areas,and two perpendicular 3-D constructing lines at adjacent area were used to construct accurate 3-D configuration of this area.The axial surface was completely defined by the network of specified curves which were two constructing lines and four borders.Results:Inlay axial surface was smooth,the contour was consistent with the residual tooth body and the 3-D configuration in adjacent area was accurate.Conclusion:It is feasible to realize the inlay axial surface accuracy,smoothness,and consistency using the method of special distributed 3-D B-Spline curve network.
