As an effective means to protect teeth, beauty crown has been accepted by many people. How can the specific curative effect of beauty crown last? A dentist in Zhengzhou Jimei Plastic Surgery Hospital said that the specific duration of beauty crown is related to many factors. Let's follow Jimei experts to understand the specific content: first, the choice of cases. If the abutment is healthy, the occlusal relationship is good and the patient's oral hygiene is good, then the prognosis of the cosmetic fixed bridge will be guaranteed to some extent. If the case selection is improper, the abutment condition is not good, the occlusal relationship is not good, the patient can not maintain good oral hygiene, and the prognosis of the fixed bridge is not good. Secondly, tooth preparation must ensure a certain shape of retention resistance, but also consider how to protect the health of gums and pulp. Thirdly, technicians should ensure accurate shaping, good edges and shapes, and ensure the quality of the base crown in the production process. In addition, when wearing teeth, it is necessary to adjust the occlusion to normal to ensure that the middle, front and lateral occlusion are barrier-free and the contact points are normal. Fourthly, the service life of beauty crown is closely related to postoperative care. According to the current life expectancy statistics in beauty crown, about 65% can be used for more than 20 years, which depends on the patient's own care. If you don't brush your teeth and chew casually, it will greatly reduce its service life. When you brush your teeth carefully, go to the hospital regularly to wash your teeth, avoid eating hard food (normal use), and make high-end and expensive alloy porcelain teeth. Then, its longevity can be realized for life. A good beauty crown depends on the standardized operation of clinical engineers, correct design, professional repair theory and close cooperation of technicians, otherwise it is difficult to achieve the ideal repair effect.
