زمینه و هدف: یکی از عوارض جانبی استفاده از دستگاه ثابت ارتودنسی در درمان ناهنجاری های دندانی یا camouflage تحلیل ریشه است که در دندان های مختلف دیده می شود. اگر تحلیل در انتهای اپیکالی ریشه باشد قابل ترمیم نیست، لذا بنا به اهمیت این موضوع در درمان های ارتودنسی و پیشگیری از کاهش و تحلیل پیش رونده طول ریشه، مطالعه حاضر با هدف بررسی میزان تحلیل ریشه در بیماران درمان شده با دستگاه slot 018 standard...
Introduction & Objective: The aim of this study was todeterminetheamount of external apical root resorption(EARR)within two orthodontic appliances (standard edgewise and MBT). Material & Methods In this retrospective study, panoramic radiographs of 83 orthodontic patients (27 male and 56 female) were evaluated. 46 patients had been treated with standard edgewise appliance (29 patients with e...
Ever since Edward Angle introduced his edgewise appliance in 1925, orthodontic innovators have been working to improve on not only its original design, but also the method of attachment. Our "strap-ups" have evolved from banding to bonding, from labial to lingual, and from metallic to clear. But, as Angle would be pleased to learn, we still call it edgewise.
The aim of this in vitro study was to investigate the frictional characteristics of two types of self-ligating brackets ('A' Company Damon SL and Adenta Time brackets) and two types of pre-adjusted edgewise brackets (TP Tip-Edge and 'A' Company Standard Twin brackets). The test brackets were glued to steel bars and aligned using a preformed jig. Five combinations of archwire size and material w...
Orthopedic expansion of the maxillary arch--rapid maxillary expansion (RME)--is a commonly used treatment technique that has become increasingly popular during the last 25 years. During this time, however, clinicians routinely have imputed a variety of undesirable side effects to RME, particularly bite opening. Whereas there have been many explanations as to the mechanisms underlying such RME-r...
This report describes the treatment of a 15-year-old female patient with Angle Class I malocclusion, severe maxillary anterior crowding, maxillary midline shift to the left, and maxillary atresia associated with posterior crossbite. The treatment consisted of palatal expansion using a modified Haas expander and placement of a standard Edgewise fixed appliance. Interproximal reduction was perfor...
Background and Aim: External apical root resorption is a common iatrogenic consequence of orthodontic treatment. Much controversy exists in the literature about changes in root lengths at post treatment periods. Although many practitioners believe that resorption becomes stable after active treatment, quantitative data are scarce. The purpose of this study was to determine quantitative changes ...
مقدمه هدف از انجام این تحقیق بررسی تغییرات سفالومتریک بافت نرم بیماران Class I با Bimaxillary dentoalveolar protrusion (B.D.P) پس از درآوردن دندانهای پرمولر اول فک بالا و پایین بوده است. مواد و روشها 20 بیمار زن Class I دارای B.D.P. با محدوده سنی 12 تا 38 سال و میانگین سنی 6±16 سال انتخاب شدند. همه بیماران بعد از درآوردن پرمولرهای اول هر دو فک با دستگاه standard edgewise درمان شدند. جهت بر...
