The use of alloplastic prostheses for temporomandibular joint reconstruction

Advances in temporomandibular joint reconstruction in TMJ ankylosis : Our experiences and literature review

“…Wear particles can generate a giant cell foreign body reaction with potential loosening of the implant, resulting in occlusal change or displacement or fracture. Other problems relate to long-term stability, cost, dystrophic bone formation, and lack of growth which precludes the use of such joints in children (Kent et al 1994, Mercuri et al 2000. Custom-made total joint prostheses for TMJ reconstruction , custom-made prosthesis, made with orthopaedically proven structural materials, in combination with autogenous peri-implant fat grafting significantly improved the predictability and success rates of treatment for the rehabilitation of complex TMJ patients with inflammatory diseases, connective tissue/autoimmune diseases, ankylosis, tumors, or absence of TMJ structures (Larry et al 2000 ) (Fig.…”

Alloplastic or autogenous reconstruction of the TMJ

“…A free graft requires a good vascular bed to take and scarred tissue carries less vascularity 16 with capillaries able to penetrate a maximum thickness of 180e220 microns (mm) of tissue, whilst scar tissue surrounding previously operated sites averages 440 microns (mm) thickness. Revision surgery with costochondral, or indeed any nonvascularised graft therefore carries a high risk of failure and alternative techniques using either vascularised or allogenic materials should be used for revisions.…”

Autogenous Coronoid Process for Condylar Reconstruction in TMJ Ankylosis Patient: A Case Report

“…[3,4] The main goals of reconstruction are: improvement of mandibular form and function, reduction of disability and pain, excessive treatment cost; and prevention of further morbidity. [5] Autogenous grafts derivedfrom distant sites such as costochondral and sternoclavicular are well established, but have their disadvantages such as exploration of the second surgical site, donor-site morbidity, bone resorption, and unpredictable growth. [6,7] Alloplastic prosthesis have achieved popularity, butare of limited use because of their cost and availability, in developing countries.…”
