This study compared the changes in alveolar ridge height in adult and adolescent patients with Angle Class I malocclusion before and after orthodontic treatment.
A total of 110 patients, 55 adults (18 years and above) and 55 adolescents (10 to less than 18 years), were included. The research focused on alveolar bone thickness and changes in ridge height.
Results showed no significant differences in alveolar ridge thickness between the groups at various locations. Adults had thinner alveolar ridges at 7 mm and 9 mm compared to adolescents. Post-treatment, adults experienced increased ridge height in specific regions, while adolescents had minor changes. Some craniofacial angles and chin concavity differed between the groups. Adults exhibited a higher incidence of bone cracking, with an increase post-treatment. Adolescents didn't show significant changes in bone cracking.
In conclusion, orthodontists should customize treatment for Angle Class I malocclusion based on age-specific findings. Adolescents may experience minor alveolar changes, while adults exhibit increased ridge height and higher fracture risk post-treatment. Monitoring and adapting plans accordingly ensure effective and safe outcomes.
本研究比较了安氏I类错牙合成年患者和青少年患者正畸治疗前后牙槽嵴高度的变化。
共纳入110例患者，其中55例成年人（18岁及以上）和55例青少年（10至18岁以下）。研究重点关注牙槽骨厚度和牙槽嵴高度的变化。
结果显示，各部位组间牙槽嵴厚度无显著差异。与青少年相比，成年人在7毫米和9毫米处的牙槽嵴更薄。治疗后，成年人特定区域的牙槽嵴高度增加，而青少年变化较小。两组之间的一些颅面角和颏部凹陷有所不同。成年人骨裂发生率较高，治疗后有所增加。青少年骨裂情况无显著变化。
总之，正畸医生应根据年龄特异性结果为安氏I类错牙合患者定制治疗方案。青少年可能经历较小的牙槽变化，而成年人治疗后牙槽嵴高度增加且骨折风险更高。相应地进行监测并调整方案可确保有效且安全的治疗效果。
