Fracture tooth to alveolar crest , what is the best way to produce ferrule effect?
A- Restore with amalgam subgingivally
B- Crown lengthing
C- Extrusion with orthodontics***
--------------------------------
The loss of dental structure below the gingival margin and bone, whether due to caries, traumatic fractures, wear, root resorption or iatrogenic perforations, makes prosthetic treatment difficult and requires treatments to achieve optimal and stable long-term results.
The main therapeutic options, due to the loss of dental structure, are exodontics, coronary lengthening with surgery or extrusion by orthodontic means.
Orthodontic extrusion is an orthodontic technique through which a tooth is intentionally moved several millimeters in a coronal direction in a very short time (a few weeks) through the application of soft and continuous forces.
There are six criteria to assess whether a tooth can be treated with orthodontic extrusion or, on the contrary, it must be extracted, established by Kockich:
- Root length. At the end of the extrusion the minimum ratio of the crown-root ratio must be 1: 1, that is, the root is at least the length of the crown.
- Root shape. It is preferable that it is wide and not conical since it has a better prognosis.
- Fracture level. If there is a fracture of 2 to 3 millimeters below the gum, traction is difficult.
- Esthetic. If the patient's smile is high (with a gingival exposure of 2 to 3 millimeters), it will be more aesthetic to keep his tooth.
- Endodontic-periodontal prognosis. If the tooth has a severe periodontal defect, it may not be possible to maintain the root.
