JCDR - Canine relationship, Molar relationship, Occlusal characteristics, Occlusion
Methods: Modification in Angle's classification has been proposed for Figure 1: Primary second molar cuspal relationship – Occlusal view . However, few other investigators have used primary canine's relationship to. Edward Angle, who is considered the father of modern orthodontics, was In case where the first molars were missing, CANINE relationship is. 12 schools Primary canine relationship using the following classification [9,11] . step governs the progress into Angle's Class I or Class III molar relationship.
Among the much discussed weaknesses of the system is the fact that it only considers the static occlusion, that it does not take into account the development and causes aetiology of occlusion problems and it disregards the proportions or relationships in general of teeth and face.
Alternative systems have been suggested by, among others, Simonthe first three-dimensional classification systemJacob A.
Salzmannwith a classification system based on skeletal structures and James L. Ackerman and William R.
A small underdeveloped jaw, caused by lack of masticatory stress during childhood, can cause tooth overcrowding. Tumors of the mouth and jaw, thumb suckingtongue thrustingpacifier use beyond age 3, and prolonged use of a bottle have also been identified as causes.
Several studies have shown this effect in humans.
ANGLE’S CLASSIFICATION OF MALOCCLUSION | DENTODONTICS
The mandible underwent a complex series of shape changes not matched by the teeth, leading to incongruity between dental and mandibular form. These changes in human skulls may have been "driven by the decreasing bite forces required to chew the processed foods eaten once humans switched to growing different types of cereals, milking and herding animals about 10, years ago.
Surgery may be required on rare occasions. This may include surgical reshaping to lengthen or shorten the jaw orthognathic surgery. Wires, plates, or screws may be used to secure the jaw bone, in a manner similar to the surgical stabilization of jaw fractures. Very few people have "perfect" alignment of their teeth. However, most problems are very minor and do not require treatment. I also feel that many of us have work of substance, newer ideas, adequate clinical materials but poor in medical writing and hesitation to submit the work and need help.
JCDR provides authors help in this regards. Timely publication of journal: Publication of manuscripts and bringing out the issue in time is one of the positive aspects of JCDR and is possible with strong support team in terms of peer reviewers, proof reading, language check, computer operators, etc.
This is one of the great reasons for authors to submit their work with JCDR.
This facility not only provides the prompt publications of the manuscripts but at the same time also early availability of the manuscripts for the readers. Indexation and online availability: Indexation transforms the journal in some sense from its local ownership to the worldwide professional community and to the public.
Manuscriptspublished in JCDR are available on major search engines ie; google, yahoo, msn. In the era of fast growing newer technologies, and in computer and internet friendly environment the manuscripts preparation, submission, review, revision, etc and all can be done and checked with a click from all corer of the world, at any time. The mesiobuccal cusp of the maxillary first permanent molar occludes with the mesiobuccal groove of the mandibular first permanent molar.
The distal incline of the maxillary canine occludes with the mesial incline of the mandibular first premolar. The molar relationship shows the mesiobuccal groove of the mandibular first molar is DISTALLY posteriorly positioned when in occlusion with the mesiobuccal cusp of the maxillary first molar.
Usually the mesiobuccal cusp of maxillary first molar rests in between the first mandibular molar and second premolar. The molar relationships are like that of Class II and the maxillary anterior teeth are protruded. Teeth are proclaimed and a large overjet is present. The molar relationships are Class II where the maxillary central incisors are retroclined.
