• Status: Unknown
• Phase: N/A
• Study type: Interventional
• Enrollment: 30 (estimated)
• Sponsor: Cairo University · Academic / Other

Summary

The aim of this study is to evaluate the treatment effects of conventional twin block appliance versus modified twin block appliance in the treatment of patients in growing stage having skeletal class II division 1 with mandibular deficiency.

Detailed description

in this randomized controlled trail there are 2 groups , the first group will receive modified twin block appliance ,in the second group will receive conventional twin block appliance . the follow up period will be 9 months till mandibular growth occur . the assessment will be through a questionnaire on the number of hours the appliance is worn each day , and another questionnaire assessing the difficulty of speech and aesthetics . Also by, photographs, x-rays and study models preoperative and post operative.

Conditions

• Class II Division 1 Malocclusion

Interventions
