摘要
Abstract
Objective Magnetic resonance imaging(MRI)was used to study the efficacy of modified anterior splint(MAS)combined with anterior repositioning splint(ARS)in maintaining the normal disk-condyle relationship.Methods We obtained clinical and imaging data of 10 patients with acute anterior disk displacement without reduction(ADDwoR)of the temporomandibular joint undergoing successful mandibular manipulation in the Affiliated Stomatolog-ical Hospital,Nanchang University from January to June 2024.The MAS and ARS were used for subsequent treatment.Maximum active mouth opening(MMO)and visual analogue score(VAS)were recorded before treatment and 2 weeks,1 month,and 3 months after treatment.The changes in the disk-condyle relationship,disk-condyle angle,joint effusion,and double contour sign before and after treatment were analyzed through MRI.Results Three months after treatment,the MMO increased from 28.90 mm to 46.85 mm,VAS decreased from 4.68 to 0.61,and the disk-condyle angle de-creased from 58.84° to 25.99°.MRI analysis found that 6 patients showed normal disk-condyle relationship,2 patients exhibited displacement with reduction,and 2 patients exhibited ADDwoR.The disk-condyle angle was 58.84° before treatment and 25.99° after treatment.Conclusion The MAS combined with ARS could further stabilize the co-ordinated disk-condyle relationship and reduce the recur-rence rate.关键词
