편측 구치부 교차교합을 동반한 과발산형 골격성 II급 성인의 비수술 치험례

Non-Surgical Treatment of Hyperdivergent Skeletal Class II Malocclusion Adult with Unilateral Posterior Scissor Bite

This case report is about a 23-year-old female with hyperdivergent skeletal Class II malocclusion and right posterior scissor bite. Orthodontic mini-implants and transpalatal arch were used to correct the scissor bite, and extraction of four premolars were done for non-surgical treatment. By applying constant torque to the stiff stainless-steel wire on retraction of the upper anterior teeth, the inclination of them was restored. Good occlusion and esthetic profile were obtained by total arch intrusion mechanics of the upper dentition to correct the hyperdivergent pattern and gummy smile.
