Analysis of treatment templates of Angle's Class III malocclusion patients / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the morphological characters of Angle's Class III malocclusion patients and the relationship between characters and treatment options.</p><p><b>METHODS</b>A total of 472 Class III patients were collected during 1997-2000. The standardized coordinates' values of the patients were obtained by Procrustes superimposition (PS). Cluster analysis was carried out to divide the patients into different subdivisions and the relationship between treatment options and subdivisions was analyzed.</p><p><b>RESULTS</b>472 patients were divided into 14 subdivisions with special characters. The morphological templates were formed by computer. There were certain relationships between characters and treatment options.</p><p><b>CONCLUSION</b>The mechanism of malocclusion of different Class III patients are not necessarily same. The typing has significance to choose the treatment method.</p>
