مقایسه‌ی سه روش دیستاله کردن مولرهای ماگزیلا با دستگاه‌های انکوریج موقت: آنالیز المان محدود

نوع مقاله : مقاله‌های پژوهشی

چکیده

مقدمه: هدف از این مطالعه، مقایسه‌ی روش‌های مختلف استفاده از انکوریج موقتی اسکلتی برای دیستالیزاسیون مولرهای ماگزیلا با روش آنالیز المان محدود بود.
مواد و روش‌ها: در این مطالعه، سه مدل مختلف المان محدود ساخته شده است که سه روش مختلف دیستالیزاسیون را نشان می‌دهد. در مدل 1، مینی اسکرو در ناحیه‌ی میانی کام وارد شده و به عنوان انکوریج اسکلتی برای حرکت دیستال مولرهای ماگزیلا اول و دوم استفاده شده است. در مدل 2، مینی اسکرو در باکال قرار دارد. در مدل 3، از پلیت پالاتالی برای دیستالیزاسیون مولر استفاده شده است.
یافته‌ها: در مدل 1 و 2، حرکت دیستالی هر دو مولر قابل مشاهده است. اما در مدل 3، مقداری حرکت مزیالی در کاسپ باکال مولر اول و هر دوکاسپ مولر دوم مشاهده شد. حداکثر میزان دیستالیزاسیون مولر اول و دوم در مدل 2 رخ داد.
نتیجه‌گیری: حداکثر جابجایی باکولینگوالی در مدل 1 مشاهده شد. حداکثر دیستالیزاسیون و تیپینگ مزیودیستالی مولر اول و دوم در مدل 2 رخ داد.
کلید واژه‌ها: پیچ استخوانی؛ آنالیز المان محدود؛ انکوریج

Comparison of different methods used for maxillary molars distalization with Temporary Anchorage Devices: A Finite Element Analysis

چکیده [English]

Introduction: The purpose of this study was to compare different methods used for maxillary molars distalization with Temporary Anchorage Devices (TADs) with a Finite Element Analysis (FEM) method.
Materials and Methods: In this study, three different finite element models were constructed to represent three different methods of distalization. In model 1,a mini screw was inserted in the midpalatal area and used as a skeletal anchorage for the distal movement of the first and second maxillary molars. Model 2 was designed based on the insertion of mini screw in the buccal area. In model 3,a palatal plate was used for molar distalization.
Results: IIn this study, three different finite element models were constructed to represent three different methods of distalization. In model 1,a mini screw was inserted in the midpalatal area and used as a skeletal anchorage for the distal movement of the first and second maxillary molars. Model 2 was designed based on the insertion of mini screw in the buccal area. In model 3,a palatal plate was used for molar distalization.
Conclusion: In model 1 and model 2, distal movement of both molars occurred, but in model 3, some mesial movement was seen in buccal cusp of the first molar and both cusps of the second molar. Maximum distalization of the first and second molar occurred in model 2.
