Introduction: The management of TMJ ankylosis poses a great challenge due to high recurrence rate.  A no. of inter positional materials let it be alloplastic or autogenous tissues have been used. The adaptive centre is preferred rather than growth centre as given in literature.  SCG is presumed to be more suitable inter positional material after TMJ arthroplasty.

The Aim of this article is to report that SCG is more similar developmentally, morphologically, anatomically and show less recurrence that CCG.

Material and Method: This prospective study included 15 patients of unilateral TMJ ankylosis. Age of patients 8 – 18 years, duration of ankylosis presented from 5 to 10 years. 12 patients had history of trauma in childhood, 3 patients had ear infection. After diagnosis patient were divided in 2 groups Group Asternoclavicular graft, Group B – Costochondral graft.

Results: In group A – Mouth opening at 6 months was 35.4 mm. Significant growth of mandible as compared with group B. Follow up at 5 years and there was no recurrence or any reunion was reported. In group B – 2 Patients had recurrence and reported after 3 years.

Conclusion: Reconstruction of TMJ with sternoclavicular graft was more effective with regard in interincisal mouth opening, recurrence , growth of mandible and articular function.
