現今許多矯正治療都會運用透明牙套,並逐漸成為患者的主流選擇。臨床治療中有許多不同透明牙套的材料。本研究目的在比較三家不同廠商製造的膜片對於輕度前牙擁擠的治療效率。評估的第一種材料來自Scheu Dental 的Duran-T膜片, 其成分是聚對苯二甲酸乙二醇酯 (PET-G);第二種是BenQ的EasyDU膜片,其成分含有全氟丁烷 (PFB)和全氟化合物(PFC)的聚對苯二甲酸乙二酯(PET);第三種是來自MaxFlex的膜片,其成分是熱成型聚氨酯(TPU)。為了比較這三種材質,製作了三個客製化的蠟牙模。每種材質使用九到十幅牙套完成治療。實驗數據通過兩種統計方法進行比較。第一種是使用one sample T-test 比較對照組(在治療計畫中每個步驟利用3D打印機列印出的樹脂模型)和實驗組(客製化的蠟牙模)之間的相似性。第二種統計分析是使用one-way ANOVA來計算三種材料實驗組與對照組每一步的治療相似百分比。本研究統計分析數據結果顯示各個材料的對照組與實驗組從 one sample T-test 計算出來的P值均大於0.05,證明H0 = H1,說明對照組與實驗組之間無顯著差異。使用one-way ANOVA計算的結果都顯示P值也均大於0.05,所以H0=H1,即顯示對照組與實驗組均無差異,表明三個品牌的治療都與對照組非常相似。研究結論證明三種常見透明牙套材質都能有效與正向的達到治療效果。未來研究方向使用更精準的研究紀錄方式來觀察牙根移動位置,進行體內研究,並擴展比較更新穎的材料,如直接列印的牙套,以確認其治療效率。
Clear aligners have become a popular choice in modern orthodontic treatments and are increasingly favored by patients. There are various materials used for clear aligners in clinical treatments. Given the diversity of aligner materials available on the market, this study aims to compare the treatment efficiency of films from three different manufacturers for mild anterior crowding. The first brand is Scheu Dental’s Duran-T film, composed of polyethylene terephthalate glycol (PET-G). The second is BenQ’s EasyDU film, made from polyethylene terephthalate (PET) with perfluorobutane (PFB) and perfluorinated compounds (PFC). The third is MaxFlex’ plastic coping sheet, made from thermoplastic polyurethane. For the experiment, customized wax typodonts were created for each of the three materials. Each material required nine to ten sets of aligners to complete the treatment. The experiment’s results were drawn using two statistical comparison methods. The first method used a one-sample T-test to compare the similarity between the control group (treatment plan models created by 3D printing resin models for each step) and the experimental group (customized wax typodonts). The second method employed one-way ANOVA to calculate the treatment similarity percentage for each step between the experimental and control groups for the three materials. Statistical analysis showed that the p-value for all materials in the one-sample T test were greater than 0.05, confirming H0=H1, indicating no significant difference between the control and experimental groups. The results from the one-way ANOVA also showed p-values greater than 0.05, indicating H0=H1, and thus, no significant difference between the control and experimental groups, showing all three brands have effective treatment results. The study concluded that all three commonly used clear aligner materials are effective in achieving treatment results, suggesting their efficiency for clinical applications. Future research could focus on detailed observations of root movement, conduct in vivo studies, and expand comparisons to include newer materials, such as direct-printed aligners, to evaluate their treatment efficiency.
