Concomitant Treatment of Mandibular Ameloblastoma and Bilateral Temporomandibular Joint Osteoarthritis With Bone Graft and Total Joint Prostheses

A Case of an Extensive Keratocystic Odontogenic Tumor in the Mandible Reconstructed with a Custom-Made Total Joint Prosthesis

“…40 Most TMJC devices installed over the years have been straightforward local TMJ reconstructions, but more recently they have been used to bridge increasingly large mandibular defects. [41][42][43][44] Westermark et al reported a series of four cases where the prosthetic components were designed to restore major defects in the zygomatic arch, mandibular ramus, and body, including one case in which the mandibular component was used to restore total mandibular continuity. Follow-up was up to 6 years, and they concluded that a customized prostheses combined with TMJ reconstruction is a reliable treatment alternative for bridging complex, major maxillomandibular defects.…”

“…42 Other case reports show similar promising results with the extended type of TMJ prostheses in function up to 3 years. 43,44 When using such a big piece of alloplastic device, there is theoretically a risk of condylar sag, especially in congenital deformity cases where the pterygomasseteric sling is totally or partially absent. A modification which is standard nowadays in all extended TMJC devices is a smooth edged hole that has been introduced just inferior to the condylar head.…”

“…The fossa component consists of an ultra-high-molecular-weight polyethylene (UHMWPE) articulating surface and the ramus component is made of a machined alloyed titanium with a condylar head of chrome-cobalt-molybdenum (Cr-Co-Mb) 40.

Relationship of temporomandibular disorders with selected systemic diseases

“…Do występujących symptomów można zaliczyć problemy kliniczne w mięśniach żucia, upośledzenie zakresu ruchu żuchwy oraz pojawiający się ból. [53][54][55][56] Schorzenie można diagnozować za pomocą CBCT, w obrazie którego występuje zazwyczaj erozja kości kłykcia, spłaszczenie i osteofity. 57 Badania dotyczące związku obecności wysięku stawowego u osób chorujących na zapalenie kości i stawów oraz ssż (diagnozowanych przy użyciu rezonansu magnetycznego) wraz z przemieszczeniem krążka stawowego bez zablokowania (PKBZ) wykazały, że w większości przypadków nie stwierdza się obecności wysięku stawowego.…”

“…Clinical symptoms may include clinical problems with masticatory muscles, impairment of jaw movement and appearance of pain. [53][54][55][56] The disease can be diagnosed on CBCT picture, typically revealing erosion of the condylar bone, flattening and osteophytes. 57 Studies on the relationship between the presence of articular exudate and osteoarthritis in the jaw joint (diagnosed using MRI) along with the displacement of the disc with reduction (DDwR) showed that in most cases there was no evidence of articular exudate in people with inflammation of bones and joints in joints with this type of displacementlocation.…”
