Questions and Answers

What is the purpose of overlap preparation covering the incisal edge?

  • To minimize the material thickness for the ceramic
  • To decrease the surface area for bonding
  • To reduce the need for color and translucency effects
  • To increase the resistance of the restoration against vertical forces (correct)
  • What is the main advantage of preparing a butt-joint overlap technique?

  • Enhanced translucency effects
  • Minimal space for material thickness on the incisal edge
  • Increased resistance of the restoration against vertical forces (correct)
  • Decreased surface area for bonding
  • In which cases is a chamfer finishing line prepared in addition to the incisal edge preparation?

  • When space for material thickness is not needed
  • When color effects are not important
  • When there is minimal thickness of the incisal edge in the labio-lingual direction (correct)
  • When protrusive movements are not a concern
  • What is the approach accepted in the current literature regarding overlap techniques?
