Abstract:

BACKGROUND: The buccal multiloop removable appliance designed by Hou et al is new-type appliance for class Ⅲ malocclusion.
OBJECTIVE: To investigate the cephalometry analysis of temporomandibular joint (TMJ) space changes before and after the treatment with a buccal multiloop removable appliance in the early stage of class Ⅲ malocclusion.
METHODS: Twenty early stage of class Ⅲ malocclusion cases, including 7 males and 13 females, aged 5-13 years, 8.5 years in average, were chosen and the cephalometric analysis was performed. X-ray pictures were done to explain the changes in TMJ space before and after treatment.
RESULTS AND CONCLUSION: The left and right linear percentages were changed before and after treatment, respectively. The left and right N/M was changed before and after treatment, respectively. Meanwhile, A and P changes could be achieved in combined treated group. All the findings indicated that the modified fixed the buccal multiloop removable appliance can lead to the reconstruction of TMJ. Meanwhile, suitable continuous orthodontic force does not lead to temporomandibular disorders.
