Soft tissue cephalometric analysis in Nepalese population

May, 2014

0

The cephalometric evaluation of craniofacial morphology forms an important tool in orthodontic diagnosis and treatment planning especially in planning the treatment outcome.­ Evaluation of the facial soft tissue features is important to set the orthodontic treatment goals to Nepalese standard of facial esthetics as no such study exists in the indexed literature.

Orthodontic appliances should be designed to satisfy goals for patient, and doctor. An appliance that is able to achieve these goals more closely approaches the ideal treatment system. Analysis of appliances of the Begg and straightwire types indicates that each treatment system has significant advantages and that the advantages of one system frequently are the disadvantages of the other.

Comparison of bracket survival rate in a sample of orthodontic patients with and without fluorosis.

In orthodontic practice, it is essential to achieve proper adhesion between the bracket and the tooth enamel. The success of the adhesion depends on the tooth surface and its preparation, the design of the bracket base and the cementing material2. The irregularities in the enamel surface caused by dental fluorosis may influence the adhesion of brackets, leading to reports of a decrease in bond strength of brackets on teeth with fluorosis3,4. The reason for this is that fluorosis is associated with hypomineralization of the superficial enamel layer, making it acid resistant, and thus reducing the effectiveness of the acid etching required to achieve adequate adhesion.

Non-syndromic Oligodontia with Impacted teeth: A rare case report

Oligodontia (multiple aplasias) is defined as a congenital absence of 6 or more teeth. Oligodontia along with impacted teeth is a rare condition. Oligodontia can occur either as an isolated condition (non-syndromic oligodontia) or it can be associated with cleft lip\palate and other genetic syndromes (syndromic oligodontia). The exact etiology of Oligodontia is unknown; several factors like trauma, radiation, infection, metabolic disorders and idiopathic conditions are the possible etiologic factors. This report describes a case of multiple agenesis of permanent teeth along with impacted teeth.

Chromium allergy in orthodontics: a review

The incidence of allergies in general is on the increase. An allergic reaction can also occur during any dental and orthodontic treatment. However, the allergic potential of orthodontic appliances is frequently overestimated. Nickel is the most common metal to cause contact dermatitis in orthodontics.

Correct alignment of teeth is a fundamental goal of orthodontic treatment. The accurate assessment of dental crowding and the space required to alleviate it is critical for correct orthodontic diagnosis and treatment planning.

A Comparison of Shear Bond Strength and Debonded Surface Characteristics of Three Orthodontic Bonding Resin Adhesive System- An In-Vitro Study

Bond failure is often attributed to moisture contamination. To overcome this commonly encountered problem, materials have been developed that are hydrophilic and that are believed to offer better bond strength in moisture-contaminated environment.

The Multipurpose Intermaxillary Hook for Elastic and Spring Attachment Abstract

November, 2013

1

The delivery of Class-I and Class-II or Class-III force from intermaxillary hooks is very common in orthodontics. There are various ways for the fabrication of intermaxillary hooks. This article highlights the fabrication and clinical use of a rigid intermaxillary hook for the attachment of intra-maxillary and inter-maxillary elastics during space closure and for Class-II and Class-III molar correction.
