Analysis of sagittal condyl inclination in subjects with temporomandibular disorders

Abstract

Bacground/Aim. Disturbances of mandibular border movements is considered to be one of the major signs of temporomandibular disorders (TMD). The purpose of this study was to evaluate the possible association between disturbances of mandibular border movements and the presence of symptoms of TMD in the young. Methods. This study included two groups of volunteers between 18 and 26 years of age. The study group included 30 examiners with signs (symptoms) of TMD, and the control group also included 30 persons without any signs (symptoms) of TMD. The presence of TMD was confirmed according to the craniomandibular index (Helkimo). The functional analysis of mandibular movements was performed in each subject using the computer pantograph. Results. The results of this study did not confirm any significant differences between the values of the condylar variables/sagittal condylar inclination, length of the sagital condylar guidance, in the control and in the study group. Conclusion. The study did not confirm significant differences in the length and inclination of the protrusive condylar guidance, as well as in the values of the sagital condylar inclination between the subjects with the signs and symptoms of TMD and the normal asymptomatic subjects.

Uvod/Cilj. Poremećena pokretljivost donje vilice jedan je od osnovnih znakova temporomandibularnih disfunkcija (TMD). Cilj ovog istraživanja bio je da se utvrdi eventualna veza između poremećene pokretljivosti donje vilice i prisutnih simptoma TMD kod mladih. Metode. Ovo istraživanje obuhvatilo je dve grupe ispitanika starosti od 18 do 25 godina. Studijsku grupu činilo je 30 ispitanika sa znacima i simptomima TMD, dok je kontrolnu grupu činilo 30 ispitanika bez znakova i simptoma TMD. Prisustvo TMD potvrđeno je uz pomoć kraniomandibularnog indeksa (Helkimo). Funkcionalna analiza kretnji donje vilice urađena je uz pomoć kompjuterskog pantografa. Rezultati. Našim ispitivanjem nije ustanovljena značajna razlika u vrednosti nagiba i dužine sagitalne kondilne putanje, između ispitanika kontrolne i studijske grupe. Zaključak. U ovom istraživanju nisu utvrđene statistički značajne razlike u dužini i inklinaciji protruzione putanje kondila, kao i vrednosti sagitalne kondilne putanje između ispitanika kod kojih postoje znaci i simptomi TMD i ispitanika bez znakova i simptoma TMD.
