OBJECTIVES: The purpose of this investigation is to find out the differences in the condylar pathways of the temporomandibular joint (TMJ) in patients treated with stabilizing splint and arthrocentesis accompanied by stabilizing splint in 6 months period.
STUDY DESIGN: Forty patients who were assigned a clinical diagnosis of internal derangement of the TMJ were included in this study. Full arch stabilizing splints were made for all patients. Patients were divided into two groups; group A (patients who underwent arthrocentesis), group B (patients who did not underwent arthrocentesis). Computerized axiography was performed for each group before therapy (T0), on the 3(rd) month (T1), after arthrocentesis (TA) (for group A) and on 6th month (T2). Curve parameters were recorded in three-dimension; X axis (posteroanterior), Y axis (mediolateral), Z axis (superoinferior). Also the distance from the starting point of the movement on sagittal plane (S) was calculated.
RESULTS: There was a significant increase in the value of Z (p = 0.014) and S (p = 0.038) in mediotrusion movement in group A. Also, there was a significant increase in the value of Z (p = 0.007) in protrusion/retrusion movement, value of Z (p = 0.019) and S value (p = 0.002) in mediotrusion movement and value of Y in open/close movement in group B.
CONCLUSIONS: No positive effects on condylar pathways of an additional arthrocentesis to splint therapy alone in patients with internal derangement were found in this study.
