What is a Class 2 procedure?
Class II restoration procedures help improve smiles by affecting pit and fissure for occlusal, buccal and lingual surface molars and premolars. Moreover, a Class II restoration can help in restoring the former glory of your teeth in general. Today’s article takes a quick dive into how a Class II Procedure takes place.
How do you make a class 2 cavity?
Envision the cavity preparation outline and extent:
- Always keep the bur perpendicular to the long axis of the tooth.
- Follow the anatomical grooves of the tooth
- Leave a small “enamel shell” interproximally to protect the adjacent tooth from iatrogenic damage.
What is a Class 2 dental restoration?
A Class II restoration has to recreate not only the natural contour of the tooth, but also the corresponding proximal contact. Many dentists consider this point, in particular, to be the most demanding part of the treatment.
What is a Class II malocclusion?
Class II occlusion occurs when the lower dental arch is posterior (more towards the back of the mouth) than the upper one. In this malocclusion, the upper front and maxillary teeth project more forward than the lower teeth and the jaw.
What is isthmus in Class 2 cavity preparation?
The transition between the occlusal and proximal cavity is termed isthmus. This is the narrowest place of preparation and it is of fundamental significance for retention of the filling.
What is MOD cavity?
Furthermore, endodontic procedure, occlusal tooth preparation, and mesio-occluso-distal (MOD) cavities are the principal procedures in the tooth weakening and consequently increase the susceptibility of the tooth to fracture.
What causes a Class 2 malocclusion?
Class 2 (or class II) malocclusions are characterized by upper molars that are too far forward compared to the lower molars. This overbite can be caused by an overly prominent upper jaw or an underdeveloped lower jaw.
How do you fix a Class 2 jaw?
Adult patients with skeletal Class II malocclusion can be treated using orthodontic (camouflage) or combined orthodontic-orthognathic surgery procedures.
What is isthmus width?
The outline must be a series of gentle arcs and curves and without acute angles. The isthmus width is between 1/3 and ½ the labio-lingual intercuspal width of the tooth. 7. Begin the proximal preparation by extending the occlusal outline form to the marginal ridge.
What is axial wall?
An axial wall is an internal wall parallel with the long axis of the. tooth (see Fig. 10). Pulpal wall.
What is MOD preparation?
Context 1. mesio-occlusal-distal (MOD) cavities were prepared with carbide burs at high speed under air-water spray (depth of 1 mm beneath dentinoenamel junction, buccolingual width of 2.5 mm, mesiodistal width of cervical surface of proximal box of 2 mm).
