Smile Designing
July 17th, 2008
Every individual desires to have a beautiful perfect smile with proper alignment of the teeth. With the help of conservative aesthetic procedures the desired results can be achieved. Few problems and the treatment modalities in this regard are discussed here:
-
Alteration of shape of natural teeth (cosmetic contouring)
-
Alteration of embrasures
-
Correction of diastemas (spaces present between anterior teeth)
-
Reshaping and polishing the natural teeth : attrition of teeth ,abnormal wear from habits (eg. Biting fingernails, holding objects with the teeth) are the common aesthetic problems.
Cosmetic contouring is done to achieve youthful, feminine characteristics like rounding incisal angles, reducing facial line angles and opening incisal embrasures.Similarly the opposite result in masculine features. The reshaping procedure is limited to enamel only.
-
Anterior teeth can have embrasures that are too open as a result of the shape or position of the teeth in the arch. For eg.- Sometime the permanent lateral incisors are missing, the canines and posterior teeth may drift mesially or the space may be closed orthodontically. In many instances mesioincisal embrasures remain too open.
Composite can be added to establish an aesthetic contour and correct the open embrasures.
-
Diastemas are spaces occurring in between the anterior teeth , usually between the maxillary central incisors. There are numerous causative factors for a diastema to occur like prominent labial frenum, congenitally missing teeth, interarch tooth discrepancies etc. Diastemas are closed only after recognizing and treating the underlying cause.
After careful selection of the case, diastema can be corrected with use of acid etch and composite augmentation of proximal surfaces. In some cases, diastemas are simply too large and composite augmentation will result in excessively large central incisors. In such cases, a combination of orthodontic and esthetic procedures is applied. With orthodontic treatment, large spaces are redistributed symmetrically amongst the anterior teeth and then composite augmentation is done. The final result is improved proportionately among the anterior teeth.
