Abstract:
Objective: To investigate the relationship of the terminal position of the muscular contraction path and centric relation position with different vertical dimension.Methods: The terminal position of the muscular contraction path and centric relation position with different vertical dimension were recorded for ten edentulous patients with gothic arch.Results: The mesial distance between the terminal position of the muscular contraction path and centric relation position increased with the vertical dimension.The lateral dimension between the terminal position of the muscular contraction path and centric relation position,the distribution of the terminal position of the muscular contraction path are not correlated to the vertical dimension.The center of the terminal position of the muscular contraction path is 1-4 mm ahead of the centric relation position and(0.42?0.47) mm lateral to the centric relation position.The distribution of the terminal position of the muscular contraction path is(1.36?0.58) mm in the mesial-distal direction,(1.56?0.62) mm in the lateral direction.Conclusion: With the increase of the vertical dimension,the mesial distance between the terminal position of the muscular contraction path and centric relation position increased.
