" Comparative Evaluation of Aggressive Gap Arthroplasty With Minimal Gap Arthroplasty in the Management of TMJ Ankylosis "

the most commonly used protocol in the management of TMJ ankylosis is Kabans protocol in which 1.5 to 2 cm aggressive resection of bone is recommended which may lead to gap between cranial base and condyle of mandible.1 However, there are certain disadvantages associated with aggressive gap arthroplasty such as pseudo articulation with shortening of the mandibular ramus, premature occlusion on the affected side with a contralateral open bite in unilateral cases,2 in bilateral cases gagging of the posterior teeth and anterior open bite.3 Few studies in the literature available agreed that minimum gap arthroplasty i.e. 5 to 8 mm of gap is sufficient for TMJ movements in all planes and recurrence of ankylosis is likely to be prevented by interposed material (graft)4 .So, a randomized control study to compare outcomes of minimal gap arthroplasty with aggressive gap arthroplasty for management of TMJ ankylosis is planned.
