Effects of the Removable and Fixed Twin block on the C- Axis, G- Axis and CG angle – A growth vector for the dento-maxillary complex and the mandible

February 2012

The growth and development of the maxilla and the mandible is being considered as an important part in orthodontics. So, normal growth of the maxilla and the mandible is considered in this study with the help of the C- axis and G- axis. Also, an angle between the C-axis and G- axis (CG angle) is introduced after setting the normal standards for 300 patients, 150 males and 150 females in 3 growth patterns.

Asymmetric extraction in a Class I malocclusion with bilateral agenesis of maxillary lateral incisors and mandibular anterior crowding

February 2012

Congenital absence of teeth (hypodontia) is the most common developmental dental anomaly in human. Certain adult patients with unique orthodontic problems contralateral tooth size differences, and maxillary/ mandibular tooth size disharmonies demand asymmetric extraction. This report describes management of class I malocclusion with congenital bilateral agenesis of maxillary lateral incisors and mandibular anterior crowding with asymmetric extraction in mandibular dental arch.

Factors Affecting Success of Mini-implants – A Review

February 2012

Mini-implants have become a routine anchorage method in orthodontic practice given their high predictability and scientifically proven benefits. The small size of miniscrew implants allows them to be placed into bone between the teeth, thus expanding their clinical applications. With more patients treated with screw implants as anchorage, their stability is gathering attention. Despite their tremendous success in facilitating treatment outcomes, the implant failure rates are widely variable and could be as high as 10-30%.This article describes the various factors affecting success of mini-implants.

Asymmetric “T” Loop archwire for Deep Bite correction – A Case Report.

February 2012

A deep bite is a very common malocclusion in orthodontics. Whenever a deep bite is present it is due to the extrusion of anterior teeth. There are three options to correct it. Correction of the Curve of Spee, intrusion and retraction by segmental mechanics and deep bite correction by a continuous loop archwire. Retraction and intrusion of the six anterior teeth under the edgewise system is usually carried out in two distinct steps: canine retraction followed by incisor retraction. In the begg and Tip- Edge techniques, canine and incisors are retracted and intruded by enmasse.

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.

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.

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 [...]
