Center of Resistance and Center of Rotation of a Tooth: the Definitions, Conditions of Existence, Properties
نویسندگان
چکیده
In the present study, the exact mathematical definitions of concepts of a “center of resistance” and a ”center of rotation of a tooth” are introduced. These concepts are widely used in the literature on orthodontic biomechanics, however they are nonstrictly defined. A center of resistance and a center of rotation are shown to exist only in particular cases. The conditions of their existence and formulas to determine their positions are given.

Correction of severe tooth rotation by using two different orthodontic appliances: Report of two cases
BACKGROUND AND AIM: Severe rotation of tooth is one of the most common problems in orthodontics and considered as a developmental phenomenon. These rotations can cause cosmetic problems, gingival recession, and traumatic occlusion. By using removable appliances, severe rotations can be treated. Furthermore, gingival damage, tooth attrition, and transposition of other teeth could be prevented. E...

The main purpose of this paper is to introduce the rotation number for non-autonomous and iterated function systems. First, we define iterated function systems and the lift of these types of systems on the unit circle. In the following, we define the rotation number and investigate the conditions of existence and uniqueness of this number for our systems. Then, the notions rotational entropy an...
متن کاملEffect of length and diameter of fiber reinforced composite post (FRC) on fracture resistance of remaining tooth structure
Introduction: Post and core has been considered for endodontically treated tooth, especially in cases with severe damage crowns. Recently fiber reinforced composite posts (FRC post) have been used in the treatment of endodontically treated teeth. Because the length and diameter of posts are effective in stress distribution, the purpose of this study is to evaluate the effect of length and diame...
