The advantages of zirconia teeth include prevention of tooth sensitivity, aesthetics, no stimulation of gums, no magnetic field, etc. The disadvantages include the brittle texture of the crown and poor wear resistance, etc., as follows: I. Prevention of tooth sensitivity: the thickness of the crown is thinner and less tooth tissue is abraded, which can protect the tooth to the maximum extent and prevent causing tooth sensitivity and pain. Second, aesthetic: the transparency of the crown is better, the color is close to the natural tooth, and the aesthetic degree is higher. Third, it will not stimulate the gums: zirconia crowns are more biocompatible and will not stimulate the gums to be red and painful, nor will they cause gum staining. IV. No magnetic field: Zirconia crowns do not generate magnetic fields and do not interfere with MRI, CT and other examinations. Fifth, the crown texture is brittle: The crown texture is generally brittle and prone to fracture when subjected to large biting forces, which is the disadvantage of zirconia teeth. Sixth, the wear resistance is poor: the crown wear resistance is poor, long-term chewing and eating can gradually reduce the height of the jaw surface of the crown, which is also the disadvantage of zirconia teeth.
