[Comparative study of four methods for determination of centric position of the lower jaw].

The objective of the study is the comparison of four (methods for the determination of the centric position of the lower jaw. The methods are as follows: Motor-reflex, described by B. Bojanov, method with swallowing described by A. Hromatka, phonetic method described by N. Popov, and G. Georgiev, reflex method described by the author. The study was performed with 50 subjects with complete and partial teeth extraction. No statistically significant differences were established with the comparison of the four methods. Coincidence between the position centric occlusion and centric relation was observed in 26 per cent of the cases.
