Claims21
A dental matrix comprising:
- a non-flat strip that is configured to be placed on an anterior tooth to restore the anterior tooth, the strip comprising at least one of:
- a first anatomic feature that is a root-crown interface;
- or
- a second anatomic feature that is a portion of an inner surface of the dental matrix that conforms to the shape of an outer surface of a region of the anterior tooth to be restored;
- the dental matrix is self-stabilizing and hands free, such that there is no requirement for a matrix stabilizer to conform the dental matrix to the anterior tooth;
- the dental matrix is self-stabilizing and hands free from the at least one of the first anatomic feature or the second anatomic feature;
- and
- the dental matrix has a height that is within a range from 8 millimeters to 13 millimeters.
