The method of preparation differs between dental practitioners. Take for example the ways of interproximal preparation. Some dentists would opt for no contact point involvement, others would be happy to make the teeth preparation up to the contact point level, whereas the others would prep the tooth pass contact point. Also, regarding labial surface coverage, there are basically 3 types: No incisal involvement, Feathered incisal edge
and the Incisal overlap.
In conclusion, times have changed, and we’re living in the age of abundance and of many choices. In the past, the only way to correct dental imperfections was to cover the tooth with a crown. Today, in most cases, there are several possibilities from which to pick: crown, composite resin bonding, cosmetic contouring or orthodontics.
