4.The means of the anterior guidance and condylar guidance were 37.06±8.67˚ and 53.63±13.59˚ respectively in experimental group I .
5.The means of the anterior guidance and condylar guidance were 57.64±7.38˚ and 36.65±8.46˚ respectively in experimental groupⅡ.
6.The means of the anterior guidance and condylar guidance were 49.56˚±12.72˚ and 43.06˚±10.60˚ respectively in experimental groupⅢ.
