Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months. [3]
In this procedure, a dentist or orthodontist attaches braces to certain teeth (typically the canines and premolars) and inserts wiring, but not elastics, between the upper and lower teeth in a figure-8 pattern. The wiring is removed periodically to allow the jaw joints to move freely, especially in the vertical direction.
A fiberotomy or pericision is an orthodontic surgical procedure designed to sever the gingival fibers around a tooth. It usually reduces the tendency to relapse of tooth rotations corrected by dental braces or other treatments. [1] The most frequently encountered post-orthodontic problem is the retention of re-established tooth position.
The time required for braces varies from person to person as it depends on the severity of the problem, the amount of room available, the distance the teeth must travel, the health of the teeth, gums, and supporting bone, and how closely the patient follows instructions.
After braces treatment, patients can use a transparent plate to keep the teeth in alignment for a certain period of time. After treatment, patients usually use transparent plates for 6 months. In patients with long and difficult treatment, a fixative wire is attached to the back of the teeth to prevent the teeth from returning to their original ...
Implants preserve the integrity of the teeth adjacent to the edentulous area, and it has been shown that dental implant therapy is less costly and more efficient over time than tooth-supported FPDs for the replacement of one missing tooth. The major disadvantage of dental implant surgery is the need for a surgical procedure. [17]
The expansion process usually results in a large gap between the patient's two top front teeth, often known as diastema. This gap is closed naturally and the teeth may overlap which leads to braces being needed. Some may develop a large space while others do not develop a space at all.
As a general rule, at least 4 mm of sound tooth structure must be exposed at the time of surgery. This, allows for proliferation of the supracrestal soft tissues, which are estimated to cover 2– 3 mm of the coronal root structure thereby leaving 1–2 mm of sound tooth structure supragingivally.
