Autopolymerizing silastic for interpositional arthroplasty

Reconstruction of ankylosed temporomandibular joint: Sternoclavicular grafting as an approach to management

“…A variety of interposition materials have been used, such as temporalis fascia, muscles, dermis auricular cartilage, fascia lata, fat and costochondral graft as autogenous materials and non-biological material such as methyl methacrylate, silastic, silicone, and various metals 3,23,4,5,[7][8][9]11,[15][16][17][18][19]28,29 . The inherent growth (adaptive) potential within the cartilage favors the use of cartilaginous graft as the first choice for joint reconstruction among surgeons who advocate early surgical correction of growth deficiencies 9 .…”

Potential role of disc repositioning in preventing postsurgical recurrence of traumatogenic temporomandibular joint ankylosis: a retrospective review of 17 consecutive cases

“…Interpositional arthroplasty also recreates a joint space but, in addition, an autogenous or alloplastic material is introduced into the gap. Most authorities agree that recurrence of ankylosis is less likely when something is interposed between the cut bone ends (interpositional arthroplasty), and there Disc repositioning in the treatment of traumatogenic TMJ ankylosis 221 have been numerous proposals of suitable materials 2,5,8,11,13,16,19,23,24 . However, there is no single answer to an optimal material.…”

“…Various interpositional materials have been used in TMJ arthroplasty, including temporalis muscle and fascia, skin, dermis, auricular cartilage, fat, silastic and silicone 2,5,8,11,13,16,19,23,24 . The main criteria for choosing the material are cost, cosmetic consequences of graft harvesting, durability, risk of infection, biocompatibility, tolerance and prevention of recurrence 2 .…”

“…How to prevent TMJ re-ankylosis after arthroplasty or reconstruction is a challenge for oral and maxillofacial surgeons. The most frequently reported operations include gap arthroplasty, interpositional arthroplasty and excision and joint reconstruction with autogenous or alloplastic materials 2,[5][6][7][8][9][10][11][12][13]16,[19][20][21][22][23][24] . It is necessary to use an interpositional material to prevent TMJ reankylosis after arthroplasty, and this particular aspect of the treatment has been the subject of numerous discussions 2,5,8,11,13,16,19,23,24 .…”

Two-stage Treatment of TMJ Ankylosis by Early Surgical Approach and Distraction Osteogenesis

“…10 Interpositional arthroplasty is characterized by reshaping the condylar stump with eventual interposition among the articular ends of the autogenous or alloplastic material. 10 Interpositional arthroplasty is characterized by reshaping the condylar stump with eventual interposition among the articular ends of the autogenous or alloplastic material.…”
