Sequence of procedures used in management of disc displacement without reduction.

Abstract

Temporomandibular disorder (TMD), occurring in the form of articular disc displacement with- out reduction is one of the most serious and common forms of dysfunction. The aim of this article was to present a complete sequence of procedures and intervention that consequently led to the resolution of symptoms in most patients, associated with disc displacement without reduction and the resolution of joint's pain, as well as favorable results of treatment of disc displacement with reduction.

Material and methods: A group of 128 patients (86 females, 42 males) aged 20 to 42 years old, diagnosed with disc displacement without reduction undertook treatment at the Prosthodontics Clinic of the University Dental Clinic in Krakow, in period January 2020 - June 2024. Diagnosis of the condition was made on the basis of the DC/TMD (Diagnostic Criteria for Temporomandibular Disorders) questionnaire axis I (reduction in mouth opening <35 mm, oblique lowering path of mandibular motion, pain of the joint) and the results of ultrasonography (USG) of the temporomandibular joints. 121 patients reported experiencing intrinsic pain and 7 patients presented for treatment without feeling pain.

Result: Analysis of the results of the carried-out tests (maximal mouth opening, mandibular lowering trajectory deviation and pain intensity VAS + VNRS scale indicate that the displaced articular disc was unblocked and a statistically significant improvement in the clinical condition of the temporomandibular joints was achieved.

Conclusion: The proposed sequence of procedures carried out is an effective treatment for displacement of the articular disc with no reduction.
