[UBook] PDF Download Begg orthodontic theory and technique By P. R. Begg - Google ДокументиThe purpose of this study was to compare the occlusal peer assessment rating PAR index in Class I patients treated by means of Begg and Edgewise methods. The changes in PAR indices were analyzed using paired t -test. There was no significant difference in sex and age distribution between the two groups. The improvement of buccal occlusion in patients treated by Begg method 1. The duration of treatment in Begg method However, there were no significant differences between the two methods in terms of total PAR index, dental displacements, overjet, overbite and midline.

Changes observed at the end of stage II All extraction spaces are closed The crowns of the upper and lower anteriors are tipped back further than the first stage The anteroposterior occlusal relations attained in the first stage are maintained The overcorrections of rotations done in the first stage are maintained.

Too much force from horizontal elasticsb. Half flange2. Placed immediately posterior to the 2nd premolar bracket Bent opposite so that when inserted into the buccal tubes the anterior section of the archwire lies in the buccal sulci Amount of bend varies from case to case Greater force tend to eventually cause lingual rolling and distal tilting of molars Increase of excessive leverage the mesial marginal ridge of the molars are is seen to raise above the occlusal level. Although archwire variations are essential for correcting cross bite, they cannot do so without cross bite elastics that exert six to eight times more force than archwire.
Philadelphia: WB Saunders Co. Maintain all corrections achieved during first and second stages. Proper positioning of the cuspid and the lateral incisor. Do not engage the arch wire in the cuspid brackets until these teeth have been rotated by elastic thread or other means.

The outcomes were assessed clinically and radiological. Begg in Adelaide, Southorthodontists visited Dr.
Orthodontic appliances that deliver results in a shorter time period without sacrificing the quality of the outcome are preferred. A modified fixed appliance, blending the merits of the Preadjusted Edgewise and Begg appliances was tested. Thirty patients each were randomly assigned for treatment with one of the three fixed appliance techniques after qualifying for the inclusion and exclusion criteria established before the study. Peer assessment rating PAR index was used to compare the quality of treated cases. Total time as well as chairside time taken for treatment with the three techniques was also compared. There was a significant reduction in PAR scores with all the three appliances. There was no significant difference in the quality of treatment outcome between the Preadjusted Edgewise appliance PEA and the modified Begg appliance.
