Morphological study of temporomandibular joint in orthodontically treated patients by using pre-treatment and post treatment orthopantomographs
December 2011
The comparison of the condylar morphology was done in individuals before and after orthodontic treatment and the relationship between the orthodontic treatment and temporomandibular joint dysfunction (TMD) was assessed. There was no statistical association in the morphology of condylar among the groups. It was concluded that orthodontic treatment does not cause TMD.
Post distalization- Methods of Stabilization of Molars
December 2011
The term distalization means the displacement of a structure to a position farther posterior than that which it accepted at the onset of treatment. Maxillary molar distalization is needed for non-extraction treatment of dental Class II malocclusions. The traditional approach to distalize maxillary molars is with extraoral appliances. Although this method offers the advantage of stability with fewer side effects, the need for compliance and the esthetic drawbacks led clinicians to search for noncompliance alternatives.
Enigma of Lacebacks – A Review
November 2011
In preadjusted edgewise appliances, the tip built into the anterior brackets increases the tendency for anterior teeth to tip forward. This tendency is greater in the upper arch than in the lower arch because of the greater amount of tip in the upper anterior brackets. To prevent the forward tipping of anterior teeth, McLaughlin and Bennettintroduced a figure eight ligature wire, called laceback.
A Modified Delta Clasp for Class III Twin block (Clinical Tips)
August 2011
The Delta clasp was designed by the Clark to improve the retention of Twin blocks. In this article we describe a modification of the delta clasp that eliminates the need to give any extra wire component for protraction of the maxillae with reverse pull face mask.
Creating a new smile and a new life with Orthodontics
August 2011
Orthodontics is an art and a science. In addition to “straightening” teeth, orthodontists are also artists in creating the smile. Smile analysis is an important stage for the diagnosis, planning, treatment and prognosis of any dental treatment involving esthetic objectives.
Management of a Growing Skeletal Class II Patient– A Case Report
June 2011
Sagittal and transverse discrepancies often coexist in skeletal Class II malocclusions. Orthopedic growth modification can work well in such cases, provided that the remaining pubertal growth is adequate and that the clinician can time treatment to coincide with the peak growth period.
Triclosan – A Double Edged Sword
May 2011
Triclosan, a chemical well known for it’s antibacterial and antifungal properties, is available in various household and dental products. However, the safety of triclosan has been questioned in regard to environmental and human health. While the companies that manufacture products containing this chemical claim that it is safe, the United States Environmental Protection Agency (EPA) has registered it as a pesticide.
Y shaped elastic – Does precision in force application matter for correction of individual upper second molar crossbite?
April 2011
Micro implants are widely used for the correction of individual molars in a crossbite malocclusion. To correct the crossbite one has to simultaneously intrude and retract the tooth. Various authors have achieved such correction by placing a micro implant and stretching an elastic or e- chain over the occlusal surface of the tooth. Though this technique was effective in correcting the crossbite, some limitations and clinical problems were addressed.
Laser Holography and Its Applications in Orthdontics
April 2011
Holography has found a series of applications in dentistry such as the study of elastic deformations of soldered gold joints, qualitative studies of various dental structures, and the measurement of elastic deformation of prosthodontic appliances. In orthodontics, it has been used for the storage of dental casts, determination of tooth displacements, determination of centers of rotations of teeth and studies of deformation of human skulls after force application.
