OBJECTIVES
The objective of this study is to evaluate and compare the depth of curve of Spee in normal dentitions and dentitions with occlusal wear using conventional and digital software techniques.
MATERIALS AND METHODS
A total of 70 healthy human subjects were selected for this study in an age group of 20-50 years. Group A includes the stone models (dental casts) of 35 individuals with healthy (nonattrited) dentition. Group B includes stone models of 35 individuals with occlusal wear (generalized attrited) dentition. Two methods were used for measuring the curve of Spee, i.e., conventional method and three-dimensional digital analysis method.
RESULTS
Depth of the curve of Spee between these two groups was statistically the same. The Digital software analysis (Method II) gives more accurate readings when compared with the Conventional (Method I) of measuring the depth of the curve of Spee.
CONCLUSION
Depth of curve of Spee is maintained through the life. There is no statistical difference in depth of curve of Spee between the two groups and digital method give more accurate measurements.
目的
本研究的目的是使用传统和数字软件技术评估和比较正常牙列与存在咬合磨损的牙列中Spee曲线的深度。
材料与方法
本研究共选取70名年龄在20至50岁之间的健康受试者。A组包括35名牙列健康（无磨损）个体的石膏模型（牙模）。B组包括35名存在咬合磨损（普遍磨损）牙列个体的石膏模型。使用两种方法测量Spee曲线，即传统方法和三维数字分析法。
结果
两组之间Spee曲线的深度在统计学上相同。与测量Spee曲线深度的传统方法（方法I）相比，数字软件分析（方法II）给出的读数更准确。
结论
Spee曲线的深度在一生中保持稳定。两组之间Spee曲线的深度无统计学差异，且数字方法测量更准确。
