“…Recently, a ten-year review of TMJ prosthesis demonstrated that 4.5% of the prostheses developed infection (8 out of 178), all necessitating removal despite long term antibiotic therapy ( 27 ). Examination of failed and retrieved TMJR devices revealed significant surface damage between the condylar head and the articulating surface, demonstrating the early role of wear patterns and corrosion interactions ( 28 ). If there are clinical signs of infection such as persistent pain, erythema at site, chronic sinus tract or systemic signs, appropriate laboratory tests and radiographic imaging are obtained to establish a diagnosis.…”

Temporomandibular joint reconstruction (TMJR) is often necessary for patients with severe and/or refractory TMJ disease who have failed conservative treatment. TMJR aids to improve masticatory function and is associated with improved quality of life outcomes. Currently, alloplastic reconstruction is considered as the treatment of choice in most severe TMJ disorders due to its many advantages inclusive but not limited to early mobilization, stable longterm results, and significant improvement in jaw function. Broadly speaking, two types of TMJR prostheses are available for reconstruction: 1) stock, and, 2) custommade prostheses. The purpose of this article is to provide the reader with a brief overview of the basic principles and fundamentals of TMJR while referencing pertinent existing literature.

“…3b. Since the TMJ undergoes more loading and unloading than any other joint in the human body, the TJR implant must be able to withstand the stresses presented to the joint [40]. Pain alleviation is considered a secondary benefit to TJR, therefore, should not be the major goal of this surgery [41].…”

Advancements in temporomandibular joint total joint replacements (TMJR)

The goal of this paper is to review the advantages and disadvantages of the various treatment options of temporomandibular joint (TMJ) total joint replacement (TJR). TMJ articles published within the last 20 years were reviewed to collect the information on non-invasive and invasive TMD treatment methods. Recent technological advancements helped the evolution of treatment methods and offered significant value to TMD patients and surgeons. Considering the TMD levels, the therapeutic procedures can involve general health examiniations, physical therapy, medication, oral rehabilation or as an end stage clinical invention, temporomandibular joint replacement. In fact when intra-articular TMD is present, the effective treatment method appears to be TJR. However, concern for infection, material hypersensitivity, device longevity and screws loosening issues still exists. Further combined research utilizing the knowledge and expertise of, surgeons, material scientists, and bioengineers is needed for the development of improved TMD therapeutic treatment.

“…Pelo facto do disco articular estar ausente, passa a existir apenas uma pequena área de contacto entre o componente condilar e o componente temporal (Van Loon et al, 2000). Independentemente do material, uma determinada carga numa pequena área de contacto, resulta em uma taxa de desgaste mais elevada, ocorrendo libertação de partículas para o organismo humano (S Kerwell et al, 2016;Mercuri et al, 2018aMercuri et al, , 2015Rodrigues et al, 2018). Os níveis de desgaste dependem de fatores como a rugosidade e qualidade dos materiais, aspectos geométricos, carga e área de contacto das duas superfícies (S Kerwell et al, 2016;Mercuri et al, 2015;Wolford et al, 2015).…”
