Orthodontic treatment of the malocclusion after TMJ arthroscopic disc reposition and fixation

Objective To evaluate orthodontic treatment after TMJ arthroscopic disc reposition and fixation.Methods From 2006 to 2007,7 patients underwent TMJ arthroscopic disc reposition and fixation.Every patient received partial or whole orthodontic treatment,and their occlusion was recorded preoperatively and at different stages after operation.Results After arthroscopic disc reposition and fixation,malocclusion occurred in all patients.With time going on,the proportion of malocclusion declined.All patients recovered after orthodontic treatment.Conclusion Malocclusion would occur after TMJ arthroscopic disc reposition and fixation.However,if malocclusion lasts for one month,Orthodontic treatment is highly recommended.
