The Relationship Of Tooth Size And Arch Form To Arch Depth, Harold C. Avila
The Relationship Of Tooth Size And Arch Form To Arch Depth, Harold C. Avila
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to determine the relationship of arch form and tooth size to arch depth measurements of study models (Casts) and their respective lateral cephalometric radiographs (Radiographs) in a population of patients treated to an acceptable occlusion without extraction. One hundred and twenty casts were divided into three tooth size classes within each of four arch form categories. Results showed there was a statistically significant change in the arch depth measurement when tooth size was varied. There was no statistically significant change in the arch depth measurement when arch form was varied. The results showed greater …

A Comparative Study Of The Permanent Deformation Of Aesthetic Polymer Brackets, Samar Bou Assi
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this study was to Investigate and compare the plastic or permanent deformation of different commercially available aesthetic polymer brackets (American, Ormco, GAC and RMO). It also examined the effect of tying the bracket wings with a wire ligature as well as the effect of thermocycling on the permanent deformation of these brackets.
Seven brackets of each type were tested In each of the three following conditions; group 1; tied with a wire ligature and loaded, group 2; thermocycled and loaded, and group 3: loaded only, with a total of 84 brackets tested. Each bracket was bonded to …
