Correction of Class II division 1 malocclusion using Functional Appliances
February 2012
Functional appliances, by altering the position of the teeth and supporting tissues, establishes a new and more optimal functional behavioural pattern which leads to adaptive changes in the bone form and helps the dentofacial complex achieve, its optimal genetic growth potential.
Bone sounding: a clinical tip for Microimplant placement
February 2012
After their introduction by Kanomi1 in 1997, microimplants have become a sensation enabling diverse clinical applications. Orthodontic miniscrews have been used to provide stable skeletal anchorage for both direct and indirect orthodontic traction. One of the challenges of microimplant placement is planning its correct positioning in the bone to achieve proper stability. The insertion technique should maximize the available bone volume while avoiding adjacent anatomical structures such as dental roots, nasomaxillary cavities, and neurovascular tissues.
Gentle Jumper- A Light Force Fixed Functional Appliance
February 2012
The hypothesized mechanism of Class II correction with Gentle jumper include:
Basal restraint of the maxilla.
Dento-alveolar retraction of the maxillary dentition.
Dento-alveolar protraction of the mandibular dentition.
Increased growth at the mandibular condyle.
Downward/forward glenoid fossa remodeling
Lateral expansion of the maxillary molars.
Semi Rapid Maxillary Expansion: A Literature Review
February 2012
Orthopedic and orthodontic forces are used routinely to correct maxillary transverse deficiency (MTD). A new approach, namely, semi rapid maxillary expansion (SRME) was introduced with the hypothesis that SRME may stimulate the adaptation process in the nasomaxillary complex and thus would result in reduction of relapse in the post-retention period.
Closed Versus Open Eruption in Management of Impacted Canines
January 2012
Impacted teeth vary according to their positions, depth, patients’ general status and “manageability”. Such variations and distinctions impose additional burdens on the practitioner to establish and successfully execute a treatment plan. One must realize that a single treatment plan will not suffice for all cases, but must be designed for each instance. However, the cornerstones in impaction cases are: Synoptic treatment plan, establishing the position of the Impacted tooth and finding the traction techniques that ultimately lead the impacted tooth into its correct anatomical position.
Diagnosis of Facial Asymmetry Using Conventional PA Cephalometric Analysis and a Maxillofacial 3-Demensional CT Analysis: A Comparative Study
January 2012
The advent of computed tomography has greatly reduced magnification errors from geometric distortions that are common in conventional radiographs. Recently introduced 3-dimensional (3D) software enables 3D reconstruction and quantitative measurement of the maxillofacial complex.
Primary Failure of Eruption (PFE) of Multiple Permanent Teeth: A diagnostic and Rehabilitation challenge
January 2012
ABSTRACT The objective of this article is to help the dentist diagnose a case of primary failure of eruption (PFE) appropriately and distinguish it from other causes of eruption failure. The literature on the possible etiology of PFE was reviewed and correlated with our patient. A systematic approach towards the diagnosis and treatment by surgical [...]
Effects of Recycling on the Tensile Strength of Beta Titanium and Nickel Titanium Wires
January 2012
The ability to recycle orthodontic wires relies on effective sterilization prior to re-use without resulting in deterioration of their clinical properties and without causing health hazard to the patient. The present study was undertaken to evaluate the changes in the tensile strength of Beta titanium and Nickel Titanium wires after recycling.
Treatment Effects in an Anterior Open Bite Class II Malocclusion with Two Different Functional Appliances
January 2012
Malocclusions characterized by anterior open bite are often difficult to treat successfully. Anterior open bite is a malocclusion characterized by a deviation in the vertical relationship between the maxillary and mandibular dental arches, with absence of contact between the incisal edges of the maxillary and mandibular teeth in the vertical plane. The severity varies, from an almost edge-to-edge relationship to a severe handicapping open bite
