Analyse the impact Twin block appliance and Motion on Hyoid Bone

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients were selected, divided en two homogenous groups and underwent preoperative and postoperative lateral teleradiograph scans. The datasets were subsequently uploaded into a digital treatment planning software to record the position changes of the hyoid bone at horizontal, vertical, angular, and airway complex level; additionally, the effect of gender, age at onset, treatment time, biotype, and their interactions with the group, have been also statistically evaluated.

Impact of Twin Block and Motion above Hyoid bone

All patients were submitted to preoperative and postoperative lateral teleradiography (Vatech D052SB, Puteaux, France), with the following exposure parameters: 75KV, Intensity10mA, exposition times 11s28, 112,8 mAs, using the Frankfort plane as reference parallel to the floor; moreover, patients were required to avoid moving and swallowing. Afterwards, digital datasets were uploaded and aligned into a digital therapeutic planning software (Orthalis®, Orqualceph®,group orqual) to accurately record the position changes of the hyoid bone at horizontal, vertical, and angular level, according the gender, facial biotype and airway complex, by measuring the following anatomical references:
