Orthodontics Dentofacials – Put that charming SMILE back on your Face.
Various features of a human face put together in different proportions give a diverse variety. Any deviation from the normal and accepted facial development and symmetry brings about unpleasant facial appearance, mental depression and diffidence.
Dentofacial deformities affect approximately 20% of the population. People with these deformities exhibit varying degree of functional and aesthetic compromise. Such deformities or malformations may involve one jaw (either upper or lower) or both the jaws or may involve multiple carmilfacia structure. They may be unilateral or bilateral and may be expressed to varying degrees in horizontal and vertical and transverse facial planes.
Orthodontics is a branch of dentistry concerned with growth of face, development of dentition and prevention and correction of occlusal anomalies.
WHY Should one opt for ORTHODONTICS?
It is observed that individual motivation has more effect upon the presence of plaque than alignment of teeth. Therefore main indications for the treatment are:
Functional reasons Include
a) Cross bites, b) Deep traumatic bite, c) Increased Overbite, d) Crowding of incisors
It is important that people realize that orthodontic treatment is not without its disadvantages. Even with good oral hygiene, a small loss of periodontal attachment and root resorption is common and in susceptible people this may be significant. With poor oral hygiene greater loss of periodontal support and decalcification may result. Therefore the potential benefit of the patient must be sufficient to counter balance these drawbacks.
When should we do orthodontics?
This depends on particular an anamoly. In early mixed dentition period Only few corrections. In mixed dentition period Major orthodontic prescription is not started. Functional appliances are used by utilizing the growth spurt. Secondary dentition. Treatment during early teens is preferred, because the response to orthodontic forces is more rapid, appliances are better tolerated and most importantly growth can be utilized.
In adults tooth movement is slower and lack of growth will limit the type of malocclusion that can be tackled by orthodontics alone. But because of the acceptability of appliance most adults are seeking prescription. Causes of malocclusion can be many. Development of normal dentition and cclusion depends on a number of interrelated factors that include dentoalveolar, skeletal and the neuro muscular factors. Thus localization of the possible etiology may be very difficult.
- Heredity has for long been attributed as one of causes.
- Congenital defects seen at the time of birth which may be caused by genetic, radiologic chemical, endocrine, infections and mechanical factors.
- Environment-various prenatal and postnatal environmental factors can cause malocclusion.
- Anamolies in number, size and shape of teeth.
- Changes in eruption time of permanent teeth or there may be prolapsed retention of milk teeth.
- Endocrine imbalance.
- Posture or poor postural habits which causes abnormal pressure and muscle imbalance.
- Accidents and Trauma.
Many people with dento-facial defects can benefit from corrective Ortho-gnathic treatment. Tremendous advancement made in the field of surgical technology for the treatment of dentofacial deformities has now made it possible to treat such people successfully in whom orthodontic camouflage would have resulted in aesthetically unacceptable and quite often unstable results. The fundamental liology behind orthognathic surgery is that the upper jaw and lower jaw bones are intentionally sectioned and re-positioned at the desired sites to correct the dento-facial deformities.
Orthodontic treatment as we know aims in improving the esthetic and function of orofacial region. Most of these changes are brought about using devices which move teeth or modify the growth of the jaws. These devices are orthodontic appliances, by means of which mild pressure may be applied to a tooth or group of teeth and their supporting structures so as to bring about necessary changes within bone and hence allowing the tooth movement.
Appliances can be mechanical or myofunctional. Removable and fixed, either of the two can be fixed or removable appliances have their own advantages and disadvantages. Usually fixed appliances are far better than removable appliances and the selection is done according to the condition. Maintenance of the appliance and oral hygiene procedure is equally important for a good result.
