Total mandibular joint replacement is a clinical strategy to treat severe temporomandibular joint (TMJ) disease. The use of TMJ prostheses was introduced into clinical practice in 1960; however, after approval by the FDA in the 1990s, its use became a regular technique for treating some TMJ diseases. Current TMJ prostheses include a fossa component and a condylar component and can be stock or custom-made. Procedures to implant the prosthesis and replace the TMJ are complex; however, technological improvements in planning have improved the process and outcomes. Despite improved knowledge of TMJ replacement, controversy remains regarding indications and timing of the technique. This narrative review aims to describe the indications, characteristics, and variables in TMJ replacement in clinical conditions related to condylar destruction or condylar overgrowth in the case of benign tumors.

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.

Bruxism is a common parafunctional activity involving repetitive jaw muscle movements during wakefulness (awake bruxism) or sleep (sleep bruxism). While its multifactorial etiology is widely accepted, the roles of occlusal interferences, temporomandibular joint (TMJ) dysfunction, stress, and sleep-related breathing disturbances remain under investigation. : This cross-sectional study evaluated associations between bruxism and occlusal discrepancies, TMJ symptoms, stress, and sleep-related variables (snoring and obstructive sleep apnea, OSA) in Romanian adults.

Purpose: To study the stress effect and distribution pattern of the first and second primary molars on temporomandibular joint in the restoration of upper and lower teeth with stainless steel precrown using three-dimensional finite element method, in order to provide theoretical basis for clinical diagnosis and treatment.
Methods: CBCT data from one male and one female aged 3, 6, and 8 years old were collected, and the first and second maxillary molar teeth, upper and lower mandible, dentition and temporomandibular joint(TMJ) data were obtained respectively. Three-dimensional finite element method was used to create the finite element models of the first and second maxillary molar teeth, upper and lower mandible, dentition and TMJ, respectively.

This study aims to uncover the variables related to the success of the intervention. A retrospective study was conducted on patients who underwent joint replacement surgery utilizing a customized alloplastic system between 2018 and 2023, comprising subjects with complete records for both the planning and follow-up phases. The Student's -test was applied with a significance threshold of < 0.
