Evaluation of the Reconstruction of Occlusal Plane by use of Ponans Angle

Telerentgenski kefalogrami 34 ispitanika s najmanje 20 prirodnih zuba korišteni su u ovom istraživanju. Ispitivana je korelacija između kuta koji nastaje spajanjem točaka PORION — NAZIO N — SPINA N AZA LIS ANTERIOR (PONANS kut) i kuta koji zatvaraju frankfurtska horizontala i okluzijska ravnina. Traženi koeficijent korelacije iznosi 0,1263. Smatra se da korelacije nema ukoliko je koeficijent korelacije manji od 0,5. U našem uzorku tražene korelacije nema, što se slaže s rezultatima Karkazisa i Polyzoisa, a nije u skladu s Monteithovim rezultatima. Nismo mogli orijentirati okluzijsku ravninu u artikulatorskom prostoru ili bezubim ustima pomoću predložene Monteithove metode u našem uzorku.In this study, teleroentgenocephalograms of 34 subjects with at least 20 natural teeth were used. Correlation between the angle formed by linking the PORION-NASION-SPINA NASALIS AN TERIOR (PONANS angle) points and the angle made by Frankfort horizontal and occlusion plane was studied. The coefficient of correlation was 0.1263. It is considered that there is no correlation if the coefficient of correlation is less than 0.5. Thus, there was no correlation in the study sample, which is consistent with the results reported by Karkazis and Polyzois, but in disagreement with those published by Monteith. In our sample, the occlusion plane could not be oriented in the articulatory space or in toothless mouth by means of the method proposed by Monteith
