Background:The study mentioned was aimed to examine the contribution of the objective measures representing anterior-posterior (AP) and vertical characteristics, dental esthetics, or their combination that are used in daily orthodontic practice in the assessment of the facial esthetics.Materials and Methods:A panel of 64 laypersons evaluated the facial esthetics of 32 boys and 32 girls, stratified over four different angle classes, on a visual analog scale. The relationship between the objective parameters and facial esthetics was evaluated by the backward multiple regression analysis.Results:Dental esthetics, expressed by the esthetic component of the index of orthodontic treatment need (AC/IOTN), appeared to be the most vital indicator for facial esthetics. The horizontal sum, a variable for AP characteristics of the patient, could be a better variable when compared with the overjet.Conclusion:Addition of this newly defined parameter to the AC/IOTN improved the prognostic value from 25% to 35%.

Context: Using Visible Light to bond orthodontic attachments is now an accepted norm, the progression being  Halogens, Low and High Intensity Light Emitting Diodes (LEDs). Since, clinical use of bonded brackets is pragmatically linked with Shear Bond Strength (SBS) and chair-side time, adhesives with shorter curing time are a boon. Hence, the aforementioned facets bear a more detailed study. Settings and Design: 6 Groups (2 Halogens, 2 Low Intensity LEDs and 2 High Intensity LEDs); Each Group comprised of 10 assemblies of Metal Brackets (3M Unitek, Gemini Series) bonded to facial surface of extracted human Maxillary 1st bicuspids. Methods and Material: Brackets were directly bonded using Standard Bonding Protocol to freshly extracted Human Maxillary Premolars. Shear Bond Strength (SBS) testing was done using Universal Testing Machine, Instron. The SBS values attained in Kg/F were converted into MPa and results subjected to a comparative evaluation. Results: Mean SBS values, in MPa, for Halogen Light Cure Systems were 8.51 and 8.86; for Low Intensity LEDs were 10.50 and 10.33 while for High Intensity LEDs 15.54 and 13.85.

The aim of this in vivo study was to compare the characteristics of esthetic, self-ligating brackets (SLBs) and metallic brackets, to find bracket bond failures with SLBs and manually ligating brackets (MLBs), bracket breakages with SLBs and MLBs and staining with the SLBs. Seven patients were compared in each group. Standard light curing bonding methods were used in both the groups. Chairside time saving, appliance efficiency and bracket bond failures were compared among the groups whereas staining was observed with the SLBs. Appliance efficiency was evaluated by peer assessment rating (PAR) scores. Results showed significant chairside time being saved in SLBs, whereas the appliance efficiency was not significant. Bond failures were found only in SLBs as well as breakages along with staining. Henceforth, we could conclude that though SLBs had advantage of saving chairside time but also had disadvantage of losing more time with bond failures. Materials and Methods Two groups of seven patients were created: First group (seven patients) received treatment with OPAL SLBs (Ultradent products, USA) and second group (seven patients) received treatment with MLBs manually ligating metal brackets (Nu-Edge, TP Orthodontics, USA). Case selection was done for both the groups. Bonding procedure was done in both groups in which primer application was done on both tooth surface and bracket base in case of OPAL SLB's while in case of MLBs, primer was applied only on tooth surface. A questionnaire was evaluated for knowing patients comfort. Results Comparison of mean values of PAR scores in both the groups for pre-, post-treatment and in the reduction of PAR scores was done. It showed that SLBs were 6.5 times quicker than the MLBs during the archwire changes, thus saving considerable chairside time. Treatment outcome after 120 days, in both groups was almost the same. The SLBs had many bracket bond failures while MLBs had none. SLBs had other shortcomings, such as bracket breakage, staining, cap opening, etc. How to cite this article Gaikwad SS, Deshpande A, Doshi SS, Mhatre A, Sonawane M.

Repositioning of the anterior dento-osseous segment posteriorly is carried out with the Anterior Maxillary Osteotomy (AMO) procedure. Maxillary excess can be corrected by a combined orthodontic and orthognathic approach.  Anterior Maxillary Osteotomy has been performed since its inception in 1921 by Cohn Stock wherein, elastic force was used to retract the anterior maxillary segment. Wassmund, Wunderer and Cupar proposed modifications for AMO. This article gives an insight of a case treated by anterior maxillary osteotomy along with fixed orthodontic treatment for correction of maxillary anterior excess.
