A novel and custom-made selective laser melting (SLM) 3D-printed alloplastic temporomandibular joint (TMJ) prosthesis is proposed. The titanium-6aluminium-4vanadium (Ti-6Al-4V) condyle component and ultra-high molecular weight polyethylene (UHMWPE) fossa component comprised the total alloplastic TMJ replacement prosthesis. For the condyle component, an optimized tetrahedral open-porous scaffold with combined connection structures, i.e. an inlay rod and an onlay plate, between the prosthesis and remaining mandible was designed...

OBJECTIVE: Temporomandibular disorders (TMD) are a group of conditions affecting the temporomandibular joint (TMJ), leading to jaw dysfunction, joint and muscle pain, and a decrease in quality of life. A communication network of pro- and anti-inflammatory mediators called cytokines maintains the homeostasis of the TMJ. This review will focus on the Interleukin (IL) family of cytokines, which have been quantified in TMJ synovial fluids in a variety of studies. IL-1α and IL-1β have pro-inflammatory effects, while the endogenous receptor antagonist (IL-1RA) inhibits the pro-inflammatory effects of IL-1...

PURPOSE: The orthopedic literature has shown an increasing incidence of prosthetic joint infections (PJIs) associated with Propionibacterium acnes (P acnes). These infections present serious diagnostic and management challenges to the treating surgeons. In this review, the authors report on cases of P acnes-related temporomandibular joint (TMJ) PJIs that have been diagnosed and treated at their institution. MATERIALS AND METHODS: After approval by the institutional review board, information was obtained through a retrospective chart review...

PURPOSE: The purpose of this study was to evaluate the stress distribution on the temporomandibular joint (TMJ) prosthesis and contralateral natural TMJ with finite-element analysis. MATERIALS AND METHODS: A TMJ implant was used to create a 3-dimensional model with a computer. This model was integrated with a mandible model created with a computer by use of computed tomography images, similar to a real TMJ replacement procedure. Masticatory loads were applied to the model...

OBJECTIVES: To discuss advantages and disadvantages of TMJ arthrocentesis techniques, identifying modifications as reported in the literature. METHODS: A PubMed web-based search was carried out, using the terms TMJ and arthrocentesis, to determine the scope of coverage in well-documented articles in English. RESULTS: Among 237 articles, 12 distinct techniques were described for TMJ arthrocentesis in 12 articles. Among 12 techniques, 5 were classified as double puncture arthrocentesis (DPA) and 7 as single puncture arthrocentesis (SPA)...

BACKGROUND: Temporomandibular joint disorders (TMD) are a group of disorders involving temporomandibular joint and related structures. Interleukine-1 receptor antagonist (IL-1Ra) is an important anti-inflammatory molecule that competes with other interleukin-1 molecules. This study was designed to investigate the possible association of the IL-1Ra VNTR variant with the risk of TMD in the Turkish population. METHODS: Peripheral blood samples were collected from 100 patients with TMD (23 males, 77 females) and 110 healthy individuals (35 males, 75 females)...

BACKGROUND: Temporomandibular joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore, and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of reankylosis. Costochondral graft (CCG) is a common treatment modality for TMJ ankylosis. One of disadvantages of CCG is unpredictability of growth pattern and risk of overgrowth...

Dislocation of the temporomandibular joint, which represents 3% of all dislocated joints reported in the body, occurs when the mandibular condyle is displaced anteriorly beyond the articular eminence. Although anterior dislocation of the mandibular condyle is well documented in the literature, superior, lateral, and posterior dislocation of the condyle is rare. Only a few reports documenting superolateral dislocation with anterior mandible fractures have been published in the past. However such dislocations without any associated fractures are even rarer...

A 54-year-old woman diagnosed with multiple sclerosis (MS) at the age of 19 years was scheduled to undergo temporomandibular joint mobilization. She was currently in a remission phase from her MS but with persistent sequelae, including impaired eyesight and muscle weakness of the limbs. In addition, the blood vessels in her upper limbs were compromised by the formation of internal shunts secondary to vascular prosthesis replacements for plasma exchange therapy in MS. After a previous joint mobilization surgery, her temporomandibular joint developed adhesions with resultant trismus...

The purpose of this study was to compare the effectiveness of four non-surgical conservative treatment methods for temporomandibular disorders (TMD). The study group comprised 40 patients with unilateral TMD who fell into group II of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Patients were divided into four groups according to the treatment method: splint therapy, arthrocentesis, medical therapy, and low-level laser therapy. Magnetic resonance imaging (MRI) was performed before treatment and at the 1-month follow-up...

OBJECTIVES: The aim of the present study was to evaluate the immediate and short-term effects of phototherapy on pain intensity, the pressure pain threshold (PPT), maximum vertical mandibular movement, and the electrical activity of the masseter and temporal muscles in women with temporomandibular disorder (TMD). METHODS: Sixty women were randomly allocated to four different groups and submitted to phototherapy with a combination of super-pulsed laser (905 nm), red (640 nm), and infrared (875 nm) light emitting diodes in the same equipment on the masseter (three points) and temporal (two points) muscles bilaterally in a single session...

BACKGROUND: Anterior repositioning splints (ARS) are used primarily for the management of temporomandibular joint (TMJ) anterior disc displacement with reduction (ADDwR). However, the exact physiological effects of ARS are still unclear. OBJECTIVE: This study investigated the short and long-term effects of ARS on disc and condyle angles / positions by metric analysis. METHODS: 22 subjects diagnosed with ADDwR were recruited. Maxillary full-coverage ARS were fabricated and MRI of TMJs were obtained before splint treatment, immediate post-insertion and 6 months after splint treatment...

The present study aimed to investigate the value of magnetic resonance imaging (MRI) in the diagnosis of giant cell tumor of the tendon sheath (GCTTS), including localized (L-) and diffuse (D-) types. A total of 38 patients with GCTTS, including 31 with L-GCTTS and 7 with D-GCTTS, diagnosed by surgery and pathology, were retrospectively analyzed. All patients underwent MRI examination. Of the 31 patients with L-GCTTS, the tumors were located in the hand and wrist (18 patients), the ankle and foot (10 cases), the knee joint (2 cases) and the temporomandibular joint (1 case)...

BACKGROUND: Temporomandibular joint (TMJ) internal derangement is a common disabling disorder that is often underestimated by society. The main goal of our study is to show the clinic improvement experienced by patients that underwent arthroscopic eminoplasty as a treatment for TMJ in our center. METHODS: 19 patients (1 male, 18 females) agreed to participate voluntarily in our study. These patients presented signs and symptoms of TMJ internal derangement and pathological MRI images, and underwent arthroscopic eminoplasty in our center...
