Thickness of luting cement.. 40micro meter



Thickness of luting cement:
a- 100 micrometer
b- 40micro meter***
c- 1mm
- Cements for luting have desired film thickness of 15: 25 microns.
- Cavity Liners(either solution or suspension liners) have a desired film thickness of 5 microns
- Bases have a final application thickness of 1-2mm(they may be thicker depending on the amount of dentin that may be destroyed).
The maximum allowable thickness is 25 µm (ADA specification No. 96)
Dental Cements.
The low 12-micron film thickness is ideally suited for luting applications.

Fixing cement and fixing composite: how to make the right decision

The growing supply of restorative materials, fixing cements and fixing composites with different suitability for different indications makes it increasingly difficult for dentists to choose the best fixation. How can everything be taken into account with this panorama?

Three useful tips:

1- Product systems: offer greater security:
On the one hand, product systems offer guidance, that is, a manufacturer's products complement each other as individual components of a complete system. Such product systems give you more security, since each component has been developed and tested together. The process is usually easier to master than when using individual products from different manufacturers with different requirements and limitations.

2- Concrete recommendations: what does the manufacturer say?
Observe the specific recommendations and advice of the manufacturer. The recommended treatment protocol is adapted to your products so that you can get the most out of them, for example, in simplified processes. For Ivoclar Vivadent fixing materials there is also an interactive support with case-specific video instructions.

3- Offer of products: very simple and easy to understand:
Look for a materials partner with a simple and easy to understand product offering. For example: Ivoclar Vivadent recommends two materials for fixing a wide range of materials and restorations of various types that complement each other perfectly:
Variolink Esthetic is an ideal cementitious composite for easy fixation of highly aesthetic ceramic restorations of lithium disilicate and glass ceramic (e.g., IPS e.max CAD / Press) and composite (e.g., Tetric CAD).
SpeedCEM Plus is an ideal fixation cement for the effective fixation of restorations prepared with zirconium oxide retention (e.g. IPS e.max ZirCAD).
