11 tooth preparation for all ceramic restorations.
Up to now traditional veneer crowns used to be standard practice when it came to restoring large front tooth defects.
All ceramic inlays onlays veneers and crowns are some of the most esthetically pleasing prosthodontic restorations.
The main objective of tooth preparation is to create sufficient space for the restorative material to exhibit excellent esthetics and fracture resistance when in function.
The retention of restorations has been achieved primarily by mechanical interlocking of the cement into irregularities on the internal surface of the fabricated restoration and the tooth preparation.
When preparing teeth for all ceramic crowns a uniform reduction will help result in optimal ceramic strength.
Ensuring sufficient tooth structure is removed will lead to better aesthetics.
Which all ceramic system is optimal for anterior esthetics.
Recommendations for preparing a tooth for a ceramic restoration the preferred instruments are the established abrasive burs from the zirconium oxide preparation set according to dr.

For ce ramic veneers the minimum required thick ness is approximately 0 3 to 0 5 mm on the buccal surface and 1 5 mm on the incisal edge.
Five kinds of luting agents are most commonly used.

The smoother the edges the lower the stresses placed on the porcelain crown which in turn decreases the potential for fracturing.
Because there is no metal to block light transmission they can resemble natural tooth structure better in terms of color and translucency than can any other restorative option.
All ceramic restorations have been used for long as restorative material in dentistry.
However the recent advances in both the material and technology of all ceramic have made them a more viable.
Equally suitable is the zirconium oxide preparation set according to dr.
