Abstract:
BjOrk and Skieller conluded after following facial growth patterns using implants in upper and lower jaw bones that stable structures, which are not influenced by the growth do exist and so these must be the reference landmarks in the process of superimposition. In spite of such facts, for the last 40 years since the discivery of stable structures, most orthodontists have preferred best fit superimposition method to structural method. Cases such as Angle's Class II division 2 malocclusion that show characteristic forward and upward growth or one under long period of poet-trdatment observation demonstrate that distindt differences exist between the two methods of superimposition. Today, ethical concerns prohidit further growth studies that use implants, and so there is no choice but to use stable structural superimposition method based on BjO;rks data. Thus, to encourage clincal use of stable structural superimposition method, logic for the use of stable structural superimposition method will be demonstrated, and its technical methods of application will be introduced step by step.
