Treatment For Unilateral Closed Locked with Jog Manipulation Technique And Simplified Myofunctional Technique And Anterior Splint Reposition

Abstract

Disc displacement without reduction (DDWoR) with limiting mouth opening is a condition that occurs in the inability to reduce the disc to its normal position also known as a closed lock. In general, there are 3 therapies used for this condition: non-surgical treatment/ conservative, minimally invasive (arthrocentesis), and surgical. Mandibular manipulation is the initial, conservative, and effective treatment in cases of acute. This paper aim to explain the treatment for closed lock patient using mandibular manipulation technique using jog manipulation and simplified myo-fuctional technique accompanied using anterior splint reposition. A 20-year-old male patient came to the Prosthodontics Clinic at RSGM USU with complaints of being unable to open his mouth wide and feeling pain in the right joint if he opened his mouth too wide.The patient had a complaint 1 week ago. Clinical examination of the patient showed a limited mouth opening which was 13 mm, left and right lateral movement was 1,2 mm and 5,6 mm. deflection with mouth opening. In this patient underwent the jog manipulation technique as mandibular manual therapy, combined with the use of an anterior repositioning splint, and the patient was instructed to self-treated at home with the Simplified- Myofunctional Technique (S-MFT). An effective jog manipulation technique can be successfully performed in acute closed lock conditions but must be accompanied by the use of an anterior splint that is immediately attached to the patient to restore disc morphology that was previously distorted. Home therapy exercises are an effective combination to prevent the displacement of the disc.
