It is the condition where the teeth present are not arranged in a proper arc. Instead, they may be placed one behind the other or out of line. Crowding can happen if the size (length) of the jaw is insufficient to accommodate all the teeth in a proper arc or, the teeth fail to come (erupt) into the mouth in the proper sequence.
Teeth can be brought into a proper position, using fixed or removable types of appliances (braces), depending on the case. In many cases, teeth are removed to accommodate the remaining teeth in proper position.
TEETH JUTTING OUT
This is a situation, where the top teeth are projecting far ahead of the bottom teeth. There could be many reasons, causing the teeth to project out. It could be that the bottom teeth are far too behind, while the top teeth are at their normal position. Alternatively, if the upper jaw, into which the top teeth are embedded, is projecting out more than the normal, the top teeth will be seen projecting out. In some cases both, the top & bottom teeth along with the jaws are placed forward.
The treatment will differ from case to case, depending on the exact cause. Sacrificing a few teeth, may or may not be necessary, to get the remaining in the most stable functional position.
GAPS BETWEEN TEETH
This is a situation where spaces are seen between the teeth. The spaces can be just between the two front teeth or between all the front teeth.
Just like in any other case, the treatment is planned after a thorough study of the teeth models, analysis of the face & teeth pictures and analysis of the x ray pictures. In these cases, most of the times, removal of teeth is not advised, unless there are other complications. Additionally, many a times, permanent retention is given to such patients
FRONT TEETH OVERCLOSE
This is a situation where the top front teeth overlap more than ¼ of the bottom front teeth. Some cases, it may be so bad that the top front teeth impinge onto the outside of the bottom front teeth and the bottom front teeth impinge on the inside of the top front teeth.
Treatment after a proper case study, mostly does not involve extraction of teeth. In some extreme cases, surgery of the jaws may be needed. Permanent or prolonged retention might be advised at the end of active treatment.
FRONT TEETH DO NOT MEET
This is a situation where one sees a gap between the front teeth because the top and bottom front teeth do not overlap each other or come in contact, when the top and bottom back teeth are touching. Normally, when we chew food, the top & bottom back teeth come in contact with each other. Simultaneously, the front top and bottom teeth almost touch each other. In open bite cases, the overlapping or contact of the front teeth is not seen. The gap between the front teeth can be caused by thumb sucking habit or because of the tongue resting between the teeth, or because of the incorrect relation of the jaws.
The treatment is directed to eliminate the reason which resulted in the gap, while simultaneously getting the teeth in proper alignment.
BOTTOM FRONT TEETH AHEAD OF TOP ONES
Normally, when one closes the teeth, the top front teeth tend to lie ahead of the bottom front teeth. Also, the upper back teeth – grinders, normally lie outside the bottom back teeth. However in certain cases, few or all the bottom front teeth come to lie ahead of the top front teeth – a situation which is orthodontically known as a “Cross bite” or “Class 3”. If any of the upper back teeth come to lie on the inside of the bottom back teeth, a “Cross bite” situation arises.
The difficulty or ease with which a cross bite can be corrected, will depend to a large extent as to whether the problem lies solely with the teeth or there’s some problem with the underlying jaws as well.
Class 3 cases, need to be detected early, so that steps can be taken to correct the problem pronto, or at least minimize the damage that might occur as the patient grows. Surgery, to cut and correctly reposition the jaws, might be needed in Class 3 cases where the jaws are disproportionately matched. The treatment may or may not involve removal of teeth
FEW UPPER FRONT TEETH CLOSE AHEAD OF BOTTOM FRONT TEETH
Normally all the top front teeth would close ahead of the bottom front teeth. However in certain cases, a few bottom front teeth end up settling ahead of the top front teeth.
In these cases, the few teeth whcih are incorrectly positioned, are traumatised a lot. The gum health & support to those teeth decline with time, compromising the health and integrity of the entire dental arch.
Cleft lip and palate is purely a developmental defect seen in new born kids, when the different parts of the face which join together to form the lips & the jaws, do not fuse completely. Cleft patients pose a unique challenge to the treating doctors and the parents this is because there are multi factorial issues with the patients. These issues involve the pediatrician, plastic surgeons and dental specialists. The orthodontist’s role is pivotal.
BRACES TO ACCOMMODATE ARTIFICIAL TEETH BETTER
When teeth are lost or removed because it were decayed & broken, and a replacement was not put, teeth on either side & opposite the space created, tend to tip/move into the space created. Quite often the dentist finds it difficult to give an artificial replacement in that space.
The Orthodontist with the help of braces can move teeth to position them correctly, so that the dentist can deliver the BEST possible replacement
