The use of implants has made a major change in orthodontic treatment mechanics. They have replaced conventional unaesthetic and compliance dependent extraoral appliances with well accepted intraoral mechanics. Implants can be used in molar and canine distalization, intrusion and in extraoral force applications. In the present case report, treatment of a case using an intermaxillary fixation scr...

Breathing is essential for life in all of its stages. Cellular, mitochondrial respiration requires an adequate supply oxygen, provided by the air we breathe, after airway conduction, treatment lungs, and transport to tissues. At different stages life, pediatric dentists orthodontists can intervene upper airway, expanding it, which helps with ventilation. The greater space, if used, contributes ...

BACKGROUND Spinal pain syndromes are among the most frequent causes of ill health. Long-lasting sustained overload results in a critical decrease in the distance between neighbouring vertebrae and radiation of pain. The aim of this study was to assess the effect of cervical traction and the TENS method on the strength of painless grip and maximum strength of the arm flexors. MATERIAL AND METH...

Titanium implants were placed surgically into the maxillary, zygomatic, frontal, and occipital bones of four pigtail monkeys. After a 4-month healing period, the implants were exposed and abutments were placed. Extraoral traction appliances were then attached to the abutments. The cranial implants were used to support the framework of the traction appliance; those in the facial bones were used ...

Background/Purpose: Phimosis, owing to the presence of a preputial fibrotic ring, is surgically treated in 1% of children. During the last decade, however, topical steroid treatment has been proposed for phimosis. Methods: We present a double-blind study comparing 0.1% mometasone furoate topical cream vs moisturizing cream (placebo) for the treatment of phimosis. Children aged from 2 to 13 year...

Extraoral traction is still one of the most reliable methods used during active orthodontic period especially in growing patients [1]. It is a practical and cost-effective method for attaining extra anchorage in a variety of treatment situations and it can be used either with orthodontic or orthopaedic purposes [2-3]. It is imperative for the clinician to consider the quality of the force syste...

The difficulty of managing this reverse anchorage potential has led to an increase in the use of extraoral forces, functional appliances, and even orthognathic surgery to correct malocclusions with relatively slight sagittal discrepancies. In his last published article, Angle advocated angulated bracket placement that would tip the crowns of the maxillary teeth distally to correct a Class II, d...

If all the forces o f nature can be reduced to those which follow from a linear combination o f a scalar and vector potential, as in electrodynamics, Lorentz invariance can be derived as a dynamic symmetry. All that has to be done is to assume that there is an all pervading substratum or ether, transmitting those forces through space, and that all physical bodies actually observed are held toge...

This article presents a multiscale study on adhesive interactions between graphene and its substrates. First, van der Waals (vdW) interactions between graphene and a SiO2 substrate are studied by fi rst-principle density functional theory (DFT) calculations with dispersion corrections. It is found that the interaction strength is strongly infl uenced by changes of the SiO2 surface structures du...
