Dental Branches Inferior

The mandibular rami (Latin: "rami dentales inferiores") are thin bones that surround the lower jaw and help hold the teeth in place. The lower rami are an integral part of the lower jaw and are attached to the lower part of the alveolar arch or alveulus. This organ contains the roots of the lower teeth, each of which is attached by a special ligament - an elastin thread, on which the tooth hangs in the oral cavity. It is the lower, small teeth that are called the first (front), and the upper ones - the back.

Based on the structure and location of the lower branches, there are eight types, each of which has its own characteristics of tooth attachment: 1. Type I can be considered normal, corresponding to the human structure. The attachment of the lower jaw to the alveolar arch is carried out by a special attachment on the posterior lower edge of the jaw, when the alveolus is located posteriorly. The elastin threads themselves have a direction, which makes it possible, when pressed from below, they are stretched; 2-3. Types II and III are not often found because, as a rule, they do not provide the necessary fastening; 4-5. types IV and V can be called orthopedic anomalies, because. Loss of the lower back tooth due to lack of attachment does not require surgical intervention. Teeth fall out spontaneously; 6. type VI is the most common type of attachment of the lower branches - observed in 90% of cases. The disorders differ in the location of the alveoli, with weakening of the attachment, so conservative methods are usually sufficient for treatment; 7. Type VII - rare, complex cases requiring surgical intervention. Is a diagnostic sign of jaw injury; 8. type VIII is extremely rare; 9. Type IX occurs when the development of the alveoli is impaired. The most important element of the dental branches with this type of attachment is their shortening. Treatment in which it is possible to save some of the teeth, but requires a number of hygiene rules.
