Real-Life Success Stories: Dental Restorations with Zirconia Blocks

Teeth are one of the important organs of the human body. A complete set of teeth is like a precision machine. If any part is damaged, the whole machine cannot function at its maximum efficiency. In addition to chewing food, teeth also play a role in pronunciation, language and maintaining facial coordination and beauty. The health of teeth directly affects your quality of life, which is why dental restoration is so important to us. With the development of modern technology, zirconia blocks have become a new type of medical material widely used in dental restoration.

The benefits of using zirconia blocks as tooth restorations are mainly the following three points: First, it does not affect magnetic resonance examinations. Since zirconia blocks are not metal, no artifacts will be generated when taking magnetic resonance images, which will affect the doctor's judgment. In addition, even if zirconia blocks exist in the mouth for a long time, there will be no harm. Unlike metal, long-term use will not cause gingival hyperplasia or gingival discoloration on the teeth. Second, the strength of zirconia blocks is relatively high. Generally, the strength of zirconia blocks is higher than that of natural enamel. In the past, it was clinically believed that materials with too high hardness would cause greater wear on teeth, but now it is found that tooth wear depends not only on hardness but also on the degree of surface polishing. If the zirconia block material is highly polished, the wear on the teeth will not be greater than that on normal enamel, but will be smaller. Therefore, using zirconia blocks to repair teeth is not only wear-resistant and pressure-resistant, but also reduces the wear on gums and teeth. Third, zirconia blocks are very hard and wear-resistant, will not collapse in the mouth, and the color is close to real teeth, making them more beautiful after repair.

Of course, the benefits of using zirconia blocks for teeth restoration are not limited to those mentioned above. In our real life, there are many successful cases of using zirconia blocks to repair teeth. The following is a classic clinical case:

Patient basic information

Gender: Male

Age: 26

Case Reports: The patient had no history of smoking and was in good general condition. The patient came to the hospital for pain in the upper left central incisor and loose crowns of the two upper central incisors. At the same time, he was worried about the aesthetic effect of the smile after the restoration. Looking back at the medical history, the patient had a fractured crown of the upper front teeth when playing basketball when he was 18 years old. After root canal treatment, he was restored with a porcelain crown. The patient said that the porcelain crown was very loose and he had been re-examined many times. Because of concerns about the potential harm of metal materials, it is planned to choose metal-free implants and restorations.

Treatment programs: The two maxillary central incisors were planned to be extracted due to poor expected treatment outcome. The patient requested a metal-free restoration. Zirconia blocks implants and all-ceramic restorations were introduced and the patient accepted this treatment.

Treatment effect: Both implants achieved satisfactory initial stability during the operation, without allergic reactions and with good biocompatibility. The patient was rechecked one month later and no problems were found. Zirconia blocks tooth restoration is both beautiful and practical.
