Retrospective comparison of autogenous cosotochondral graft and coronoid process graft in the management of unilateral ankylosis of the temporomandibular joint in adults

Facial Bone Reconstruction Using both Marine or Non-Marine Bone Substitutes: Evaluation of Current Outcomes in a Systematic Literature Review

“…Zahng et al retrospectively evaluated the outcomes of using autogenous coronoid process like bone grafts ( n = 32) and compared with costochondral grafts ( n = 28) in the condylar reconstruction in case of temporomandibular joint (TMJ) ankylosis. The clinical outcomes in both groups were satisfactory and comparable concluding how the autogenous coronoid process grafting may therefore be a good alternative for condylar reconstruction in patients with ankylosis of the TMJ [ 23 ]. Nkenke made a revision investigating numerous published papers about the morbidity related to the autogenous bone graft harvesting and the follow-up graft resorption and dental implant survival in the grafted sites.…”

“…After the study selection, a new division related to the kind of bone graft has been performed: Autlogous Bone: Thirteen studies [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]; Homologous Bone: Five studies [ 29 , 30 , 31 , 32 , 33 ]; Xenograft or Allograft material and bone derived from animal or synthetic origin: Ten studies [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ]; Marine collagen material: Eleven studies [ 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 ]. …”

“…Evaluation on the total risk of bias for each selected paper, and the majority of the manuscripts were allocated as unclear risk [ 20 , 21 , 22 , 23 , 27 , 28 , 29 , 34 , 35 , 36 ]. Three research papers were considered as having a low risk of bias [ 32 , 37 , 39 ], where another one was classified as moderate risk [ 30 ].…”

A review of temporomandibular joint-related papers published between 2014–2015

“…Abel et al 6 compared the conventional TMJ prosthesis to a customized condylar support prosthesis and found the latter to have a better physiologic form along with a better capacity to transfer load and reduce strain on the bone and screws. A retrospective comparison by Zhang et al 7 of the use of autogenous coronoid process grafts and costochondral grafts for the management of unilateral TMJ ankylosis patients yielded satisfactory results for both of the modalities on jaw deviation, mouth opening, and jaw movement parameters. Thus, they state that coronoid grafts can be a good treatment option.…”
