A full veneer crown covers the entire clinical crown of a tooth, including all accessible surfaces—occlusal, buccal, lingual, and proximal. This coverage provides maximum protection and structural support for a compromised tooth, restoring function and aesthetics. Partial coverage options, such as onlays or veneers, only cover selective surfaces and do not offer the same level of protection. The full coverage also allows for better control of occlusion and contour, ensuring long-term durability of the restoration.
