Total temporomandibular joint prosthesis

摘要

Total temporomandibular joint prosthesis, prosthesis for total joint replacement; prosthesis temporomandibular (TMJ) proposal is physically the two types of articulation in an ATM, the ginglimal and flat, which work independently or in a Next,Depending on the type of movement or force employed; the components proposed also allows interaction with the intact contralateral TMJ, keeping all the original movements; the total prosthesis of ATM includes mandibular plate (10), articulation ginglimal (Ag), condylar anchor (40) and set G Lenoidal (CG), determining a second articulation.The condylar articulation (BC); the joint ginglimal (Ag) includes joint screw (70), bushing greater (90), lower bushing (80), and four washers (100); all the glenoid (CG) comprises support (20), the glenoid glenoid socket (50) articulator (60), the glenoidAnd the closing plate (30); external and internal regions that have contact with bone tissue receive plasma coating porous titanium, to provide osseointegration and biological fixation of the component; the structural parts: glenoid support (50).A pivot (40) and mandibular condylar plate (10) are made in titanium; the articulation ginglimal (Ag) and the condylar articulation (AC) are coated with polyethylene of ultra high molecular weight.
