| Summary: | 碩士 === 臺北醫學大學 === 醫療器材產業碩士專班 === 105 === Recent advances in orthodontic research have prompted the development of digital dental therapies, using computer aid design technique compare with 3D printing modeling makes tradition orthodontic braces has a chance to evaluate into transparent plates, as known as invisible braces. Invisible braces not only improve the appearancewhile wearing bracesbut cause less pain to patient,even more invisible braces cause less scratchesbecause of its smooth surface and thin thickness.However, the treatment on invisible braces may be too long forpatient, because ofthe pulling force in some cases may not be enough. To overcome these problems, we aim to add an attachment on patient’s toothto support braces as a fulcrum for increasing turning force in the treatment.
Location, shape and size of attachmentmay cause different effective during the whole treatment, in case the design of attachment becomes a big issue in invisible orthodontic treatment. The aim of this study is to evaluate the effect on orthodontic attachment in different size and shape by use finite element analyzing assay to simulatethe stress and displacement that how different shape of attachments effect to orthodontic treatment under horizontal, vertical and oblique force, and try to find out the best designof invisible brace.
