Objectives: This paper studies the treatment effect of total joint replacement (TJR) of the temporomandibular joint (TMJ) with alloplastic joint prosthesis regarding function, symptoms and health-related quality of life compared to other surgical and non-surgical treatments in patients with TMJ disorders.
Methods: Three databases (PubMed, Cochrane Library and Web of Science) were searched up to 11 March 2025. Studies in which TJR was compared with other surgical or non-surgical methods were searched and analyzed. Data extraction and quality assessments were performed by at least two investigators independently. Risk of bias was assessed with the ROBINS-I-tool. Certainty of evidence was assessed with GRADE.
Results: A total of 2,891 studies were identified in the search. One study met the criteria with comparison of TJR with a control group consisting of patients treated with another surgical method, namely, interpositional arthroplasty. The study investigated the outcome variables such as pain reduction and improvement in mouth opening and had a moderate risk of bias. No significant difference between the groups was found after regression analysis. Quality of life assessment was not the objective of this study. No meta-analysis could be performed from this literature search, for obvious reasons.
Conclusion: TMJ reconstruction with alloplastic prostheses is rapidly evolving, with new systems continually entering the market. This review highlights the urgent need for further scientific efforts, including well-designed trials capable of demonstrating the comparative effectiveness of alloplastic TJR against other treatment modalities, ideally randomized trials with controls.

Introduction: Dental health and overall well-being are greatly impacted by temporomandibular disorders (TMDs), which encompass a spectrum of illnesses that impact the temporomandibular joint and its surrounding structures. The use of dental prostheses, including complete and partial dentures, is common among individuals with missing teeth. However, the association between denture types and the prevalence of TMD remains a subject of interest and concern in the field of oral health.

Objective: The present study aimed to preliminarily explore the temporal summation (TS) response to repetitive mechanical stimulation in patients with temporomandibular joint disorders (TMD).
Patients And Methods: Twenty patients with unilateral pain in the TMJ and 20 gender- and age-matched healthy controls were included. A modified Quantitative Sensory Testing (QST) protocol was performed including pressure pain thresholds (PPT), mechanical pain thresholds (MPT), and numerical rating scale (NRS) scores of TS effects of 10 repeated 0.

This study examines the symptomatic and clinical features and variations in characteristics, such as angle and length of the condylar path in the sagittal plane during protrusion movement, in internal derangement patients treated with exercise therapy. Patients were selected and classified using the diagnostic criteria for temporomandibular disorders (DC/TMD) axis I. The therapeutic exercise program consisted of lateral jaw movements performed daily, with gradual progression to a target of 50 repetitions per day.

Childhood obesity is an escalating global public health concern with potential long-term implications for various health outcomes, including oral health. While the association between childhood obesity and systemic diseases is well-documented, its specific impact on adult oral health remains underexplored. This study utilized a 2-sample Mendelian randomization approach to explore the causal relationship between childhood obesity and several adult oral health conditions, including gingivitis, chronic periodontitis, dental caries, temporomandibular joint disorder, and malocclusion.

Objectives: Among the minimally invasive techniques for treating temporomandibular joint disorders (TMDs) is dry needling, which can be used as a potential treatment method. This study aims to review current knowledge to understand the impact of dry needling on treating TMDs.
Methods: This systematic review was carried out in alignment with the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
