Driven by demand, orthodontic techniques continue to evolve. To date, there are five primary types of orthodontic treatment. Let's explore which dental irregularities orthodontics can correct.Effective restorative solutions now exist for this condition, achieving natural tooth color and an aesthetically pleasing appearance. The procedure involves: appropriately reshaping the undersized crown, fabricating a metal crown base, and then covering it with porcelain or composite resin. This restoration not only restores normal tooth shape and natural color but also effectively maintains chewing function.
Spacing in Front Teeth: Prevention and treatment for front tooth spacing should begin in childhood. For young adults with front tooth gaps, two correction methods are available: one involves using composite resin tinted to match natural teeth to enlarge the crown and fill the gap; the other involves moving the front teeth closer together to eliminate small gaps, enlarging one or two spaces, and then restoring the gaps with removable or fixed dentures.This corrective procedure is generally available at most dental hospitals.
Canine Teeth: Since canine teeth can affect lip movement and aesthetics, some individuals choose to have them extracted. However, removing canine teeth can cause facial sagging around the corners of the mouth, deepen the nasolabial folds, reduce facial fullness, and create an aged appearance, thereby compromising overall facial beauty. Therefore, extraction of canine teeth should be approached with caution.To preserve facial fullness, orthodontic treatment can be employed. This involves extracting or reducing the size of the teeth behind the canine teeth, then gently pushing or pulling the canine teeth into their proper position. This method takes 2 to 6 months and yields better results than extraction.
Anterior Crown Defects: Trauma, cavities, or improper brushing techniques can cause crown fractures or deep wedge-shaped defects at the crown-cervical junction. These not only compromise aesthetics but may also lead to sensitivity to hot/cold stimuli (dentin hypersensitivity), pulpitis, or alveolar abscesses. Prompt restoration is essential when crown defects occur.Currently, composite resin materials are used for restoration. The result closely resembles natural teeth and remains permanently color-stable. Even if only a root stump remains, avoid extraction. Utilizing the root to anchor a fixed denture yields significantly better results than extracting the tooth and later installing a denture.
Underbite:An underbite results from jawbone developmental abnormalities or poor habits. It is not only unattractive but also impairs chewing and development. The most common corrective method involves wearing an incline plate appliance, typically requiring 6 months to 1 year. The second approach uses elastic traction with rubber bands. Surgical intervention is another option. After correction, relapse is generally rare.
