What does “Dental overlay” mean?
Overlay is the term for a partial restoration that broadly covers the chewing surface and multiple cusps of a tooth. The actual coverage area should be confirmed as the scope of use varies depending on the literature or medical description.
What does the restoration cover?
Normally, the damaged area is repaired by covering the cusps of the chewing surface. The preparation and coverage range may be different from a crown that wraps the entire circumference of a tooth.
What do you evaluate when making a choice?
Examine the condition of the remaining tooth walls, cracks, pulp, occlusion, and surfaces that can be bonded. Consider both the extent to which cusp protection is required and the material thickness.
How do you differentiate it from an onlay?
An onlay covers one or more cusps, while “overlay” is used to emphasize coverage of all cusps. The actual extent of tooth preparation and coverage matters more than the label.
Frequently Asked Questions
Does an overlay require less tooth preparation than a crown?
Extent of preparation may vary if there are tooth walls left to utilize. See the real difference by looking at the tissue already damaged and the material space required.
Can it be used on teeth that have had root canal treatment?
It may be considered when the remaining tissue and the bonding and bite conditions are suitable. The same restoration is not used for every root-canal-treated tooth.
