In recent years, porcelain teeth have become a storm in the dental beauty industry, and porcelain teeth have become the first choice for many people who love teeth. However, after many friends have had porcelain teeth done, a black line will appear on the edge of the gums. Some people even have red, swollen and bleeding gums, which results in damaged teeth instead of beautiful teeth. What is the reason for this? Experts from Shanghai Stomatological Hospital pointed out that the phenomenon of a black line on the gum margin and blackening of the gums shortly after porcelain teeth are repaired is mostly related to the selected porcelain tooth material. Let’s take a look. Why do porcelain teeth chip? 1. Reasons for stress concentration caused by poor occlusion: After the restoration is in place and cemented, it is caused by strong bite during use due to the presence of occlusal high points that are not adjusted. Therefore, the principle of blending should be followed when trying on the restoration to avoid early contact, which may cause excessive local force and cause porcelain exfoliation. 2. Quality reasons in the processing process. This is because when porcelain teeth are processed, the manufacturer's technicians may reduce the bond between porcelain and metal due to the porcelain layer being too thick, too thin or not uniform enough, improper metal surface treatment, and irregular operations during porcelain application. 3. Reasons for porcelain tooth preparation. If the molars are unevenly ground or not in place during tooth preparation, then the porcelain teeth cannot be guaranteed to have sufficient thickness. When the porcelain layer of porcelain teeth becomes thinner, chipping may easily occur. 4. Reasons for the design of porcelain teeth. For bridges with many missing teeth, the periodontal ligament area of ??the abutment teeth should be larger, because the stress generated during chewing is the greatest here and the porcelain can easily collapse. Therefore, when designing porcelain teeth, we should try to increase the contact area with the tissue surface. 5. Reasons for the manufacturing process of metal-based crowns. The production of metal-based crowns includes more than 30 processes, including the making of working models, wax-up, polishing, and the processing of the ceramic-porcelain bonding surfaces of the base crowns. 6. Reasons for the oral doctor’s order: When giving medical orders to patients with porcelain teeth, the oral surgeon failed to objectively explain the characteristics of the restoration and guide the patient’s correct chewing habits.
