Vertical control is one of the problems occasionally encountered in Straight wire treatment. Vertical problem was addressed in a more controlled manner using Tip-Edge technique In this case report Tip-edge was used in a vertically growing individual with mild crowding, proclined upper and lower incisors with skeletal class I malocclusion.

Design Systematic reviewStudy population Orthodontic patients undergoing treatment with removable thermoplastic retainers compared with conventional fixed orthodontic appliances. The mean age of patients was between 15 and 33 years. Data sources Six electronic databases including: Scopus, Web-of-Science, PubMed, Cochrane, Clinical Trials and Grey Literature were searched in addition to a search of references in eligible studies with no restriction of language.

The carrier-transport behavior at the interface of a contact and n-type GaN was investigated for group III nitride vertical light-emitting diodes (LEDs). Three types of samples were investigated including dry-etched flat Ga-polar n-GaN (GA), dry-etched flat N-polar n-GaN (NF), and wet-etched roughened N-polar n-GaN (NR). Schottky diodes fabricated using a palladium contact revealed that carrier transport at the contact/GaN interface could be understood in terms of the barrier inhomogeneity model, in which the local shallow barriers dominated the overall carrier transport.

Typodont models of bilateral canines gingival displaced vertically for 3 mm and bilateral lateral incisors palatal displaced horizontally for 3 mm are made and every kind of the two kind models was divided into four groups: MDD, MBT, self-ligating and Tip-Edge. Each group of the two kinds of models had 5 models, so a total of 40 models for the two kinds of models were set up. The experimental models were aligned with a 0.

The purpose of the study was to analyze the effects of nonsurgical treatment on subjects with a severe skeletal Class III deformity and to directly evaluate dental and facial profile changes. Eighteen patients with severe skeletal Class III malocclusions (5 males, 13 females), diagnosed as indication for orthognathic surgery, were included in the study. The average age was 13.
