Abstract
<p>Bimaxillary protrusion, which causes facial disharmony due to protrusion and incomplete closure of the lips, has many psychological effects on the patient. We investigated whether changes in soft tissue morphology could be predicted by using the revised analysis method proposed by Arnett to determine the relationship between changes in hard tissue morphology and changes in the soft tissue profile before and after orthodontic treatment of adult patients with bimaxillary protrusion. The subjects were 30 patients who were diagnosed as having bimaxillary protrusion. We measured each item of the STCA to determine the amount of change in soft tissue using cephalograms before and after treatment, and examined the correlation between changes in the hard and soft tissues. We found some correlations between soft and hard tissue changes in the items of dentoskeletal factors, facial length, and projection TVL. These results suggest that it is necessary to understand the relationship between changes in the hard and soft tissues before and after orthodontic treatment. (J Osaka Dent Univ 2021; 55: 9-20)</p>
