Nowadays, the patients’ requirements in the placement of dental crowns are very high. Both patients, dentists and technicians strive for achieving high aesthetics and harmony with the natural dentition. In our practice at Noradent, we often have to answer questions like these: Which material should we choose and why?
What materials can be used for crowns?
- Lithium disilicate glass-ceramics – pressed ceramic
- Zirconium dioxide – zirconia
- Ceramic layered zirconia
- Metal-ceramic, etc.
The material covers all dental surfaces, thus providing resistance and greater strength during function. The greatest advantage of ceramic crowns is their high aesthetic qualities. For this reason, they are usually used for the restoration of anterior/frontal teeth.
What are the reasons for placement of a crown?
- After trauma – in the presence of fractures
- Severely damaged tooth with missing walls
- Severe tooth wear
- Discoloration due to the use of a specific type of root canal filling paste
Lithium disilicate glass-ceramics are recommended for the fabrication of single crowns in the anterior/front region (premolars, canines, incisors). Zirconia crowns can be covered with a thin layer of ceramic (ceramic layered zirconia crowns) and can be placed both in the anterior and posterior area (back teeth – molars and premolars).
Ceramic crowns are fabricated in a dental laboratory, taking into account all the anatomical requirements of the natural dentition. Determining the colour is of a paramount importance in achieving a high aesthetic result. Ceramic crowns possess the property of translucency, allowing them to transmit light like natural teeth.
Characteristics and Advantages of Ceramic/Porcelain Crowns
- High optical properties – high translucency, etc.
- Good mechanical properties
- The highest level of aesthetics
- Biological compatibility with tissues
- Abrasion resistance
- Smooth surface – prevent plaque accumulation around their edges
- Possibility of polishing with rubber and pastes in the dental office
The stages involved in the manufacturing of a porcelain crown require several visits. The Noradent team first discusses with the patient the options for restoring the respective tooth with a ceramic crown and the expected results in terms of strength and aesthetics.
In the first visit, the corresponding tooth is prepared and shaped. A temporary crown is made using a direct method in the dental office, which matches the colour and shape of the adjacent teeth. After a few days, final impressions are taken with a silicone material. Plaster models are poured in the dental laboratory, scanned, and the ceramic crown is fabricated. In the next visit, a fitting is done, and the crown is permanently cemented. If any adjustments are needed, the ceramic crown is sent back to the dental laboratory, where they are made, and then it is glazed again.
Why choose Noradent for placement of a ceramic crown?
Our team strives to achieve the best result using innovative techniques, skilled professionals and dental technicians. For Noradent, the connection between the dentist, the patient and the dental technician is of utmost importance. Only this way can a highly aesthetic and functional result be achieved for a healthy smile.
