This study is to find the chewing capability and biting ability in patients treated for correction of small lower jaw with two bite blocks named Twin Block inside the mouth.

Completed

• Conditions: Class II malocclusion

• Registration Number: CTRI/2018/03/012748
• Lead Sponsor: Anand Lukose

Brief Summary

The study was an evaluation of masticatory efficiency and functional occlusal contacts in Class II patients treated with Twin-block functional appliance. The results of the study showed that masticatory efficiency and occlusal contacts of Class II cases  treated with Twin-Block functional appliance is the better treatment option than any other method. At the early treatment phase masticatory efficiency and occlusal contact may reduce as a result of change in occlusal scheme but gradually  occlusal trimming of Twin block  increase the masticatory efficiency and occlusal contact, This change in masticatory efficiency is not statically significant thus treatment with Twin-Block functional appliance therapy did not hamper the normal nutritional requirement of the patients, so we can expect the normal growth and development of the patients during  Twin-Block functional appliance therapy.
