The teeth should all fit on a line of occlusion which, in the upper arch, is a smooth curve through the central fossae of the posterior teeth and cingulum of the canines and incisors, and in the lower arch, is a smooth curve through the buccal cusps of the posterior teeth and incisal edges of the anterior teeth.
A lingual frenectomy is performed to correct ankyloglossia (tongue-tie). [1] The removal of the lingual frenulum under the tongue can be accomplished with either frenectomy or frenuloplasty. This is used to treat a tongue-tied patient. The difference in tongue length is generally a few millimeters and it may actually shorten the tongue ...
A frenectomy is the removal of a frenulum, a small fold of tissue that prevents an organ in the body from moving too far. It can refer to frenula in several places on the human body. It is related to frenuloplasty, a surgical alteration in a frenulum. Done mostly for orthodontic purposes, a frenectomy is either performed inside the middle of ...
Surgical extractions involve the removal of teeth that cannot be easily accessed or removed via simple extraction, for example because they have broken under the gum or because they have not erupted fully, such as an impacted wisdom tooth. [2] Surgical extractions almost always require an incision.
About 2 weeks before the braces are applied, orthodontic spacers may be required to spread apart back teeth in order to create enough space for the bands. Teeth to be braced will have an adhesive applied to help the cement bond to the surface of the tooth. In most cases, the teeth will be banded and then brackets will be added.
Hand instruments are specially designed tools used by dental professionals to remove plaque and calculus deposits that have formed on the teeth. [39] [40] These tools include scalers, curettes, jaquettes, hoes, files and chisels. [39] [40] Each type of tool is designed to be used in specific areas of the mouth. [40]
Anterior open bite resulted from tongue thrusting in a 24 y.o. patient. Anterior upper teeth are not touching their counterpart. Anterior open bite (AOB) is defined as a condition in which there is no contact and no vertical overlap of the lower incisor crown with the upper incisor crown when the mandible is in full occlusion.

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.
