Essential Material Requirements for Chairside Production

The technical prerequisites for materials suitable for chairside production are as follows. These materials must be sufficiently hard to ensure long-lasting performance. However, materials that are too hard can be challenging to process in milling/cutting machines, especially since the in-office production process is expected to take a short amount of time.

Additionally, the material needs to exhibit an aesthetic appearance that closely resembles natural teeth to enhance the overall aesthetics. The chairside production method is not suitable for complex cases, such as porcelain veneers. The term “monolithic restoration” is appropriate in this context. This term describes a material that immediately meets aesthetic requirements without the need for reworking. Furthermore, materials should provide favorable conditions for bonding, especially for tooth-preserving preparation techniques, which should be prioritized.

Basic Requirements for Chairside Materials:

• Good resistance to oral conditions
• High durability
• Easy and quick machining in milling machines
• Aesthetic properties similar to natural teeth

Note: Bonding provides the best results immediately after tooth preparation.
