(牙合)曲度(occlusal curvature)即 Spee's 曲线曲度或补偿曲线曲度,它在咀嚼生理、义齿的平衡(牙合)中有着重要的意义。对(牙合)曲度的表示方法已有多种报告:①圆心角表示;②弦高表示;③半径的倒效表示;④半径表示;⑤弦斜度表示。上述表示方法均未从弦高和弦长
Occlusal curvature is the curvature of the curve of the Spee's curve or the curve of the compensatory curve, which is of great significance in the balance of the physiology and the denture. Various methods have been used to represent the curvature of the occlusal surface: ① Central angle representation; ② Chord height representation; ③ Radius inverse representation; ④ Radius representation; None of the above representations are from chord chord length
