Summary
Dental bioceramics, including zirconia, are used in restorations like crowns and implants. Additive manufacturing and direct ceramic machining are advancing dental applications, with resin cements offering better aesthetics and lower solubility.
Area of Science:
- Biomaterials Science
- Dental Materials
- Ceramic Engineering
Background:
- Bioceramics are widely used in dental restorations, including implants, bridges, inlays, onlays, and all-ceramic crowns.
- Dental bioceramics encompass various types such as glass ceramics, reinforced porcelains, zirconias, aluminas, fiber-reinforced ceramic composites, and multilayered ceramic structures.
Purpose of the Study:
- To review the applications and advancements of bioceramics in restorative dentistry.
- To highlight the suitability of additive manufacturing and direct ceramic machining in dental procedures.
- To discuss the properties and benefits of different dental cements for all-ceramic restorations.
Main Methods:
- Review of current literature on bioceramics in dentistry.
- Analysis of additive manufacturing techniques for dental models using CT/MRI data.
- Examination of direct ceramic machining of yttria tetragonal zirconia polycrystal (Y-TZP).
- Evaluation of commercially available cements for luting all-ceramic restorations.
Main Results:
- Bioceramics are integral to modern dental restorations, offering diverse material options.
- Additive manufacturing and direct ceramic machining of Y-TZP are increasingly adopted in dentistry.
- Resin cements demonstrate superior aesthetic qualities and reduced solubility compared to other luting agents.
Conclusions:
- Bioceramics, particularly zirconia, are versatile materials for various dental restorations.
- Advanced manufacturing techniques like additive manufacturing and direct ceramic machining enhance precision and customization in dentistry.
- Resin cements are recommended for luting all-ceramic restorations due to their favorable aesthetic and solubility profiles.
