All-ceramic crowns are made entirely of porcelain and can effectively repair tooth defects and other deformities. They offer a high degree of realistic-looking aesthetics while being minimally irritating. They also contain no metal, meaning patients don’t need to remove them for MRI scans. They typically last 5 to 10 years.
Applicable people
All-ceramic teeth are suitable for those with discolored teeth, twisted teeth, and large tooth defects. In addition, deformed teeth and enamel hypoplasia can also be improved by all-ceramic teeth.
Taboo group
1. People with loose teeth.
2. People with severe periodontal disease.
3. Those with pathological changes in the roots of teeth.
4. People with strong bite force or the habit of grinding their teeth at night.
5. Adolescents whose permanent teeth have not yet fully developed.
6. Patients with periodontal disease who need full crown and splint fixation.
7. Those who cannot accept or are unwilling to have tooth tissue removed due to psychological, physiological or mental factors.
8. Those who have a large number of missing teeth, with more than 4 front teeth missing in a row and more than 2 back teeth missing in a row.
Technical/surgical risks
1. Secondary caries: The edge of the all-ceramic crown is a common site for secondary caries. The edge seal of the restoration is destroyed due to the dissolution of the adhesive or the loosening of the restoration; or due to food impaction, poor oral hygiene, poor self-cleaning function, etc., which can cause secondary caries of the abutment teeth.
2. Pulp damage: During restorative treatment, pulp damage may occur due to unreasonable design, improper use of tools and technical operations, rough restoration production, and incorrect grinding during initial wearing and before bonding.
3. Gum damage: Improper restoration design, rough production and non-standard clinical operation can all cause gum damage.
4. Porcelain chipping: If the abutment tooth is not well prepared and the wall of the all-ceramic crown is too thin, the all-ceramic crown may break if biting hard food or in a collision. In addition, excessive bite force, tight bite or bruxism may also cause fracture.
Postoperative Care
1. Local care: Pay attention to maintaining oral hygiene, clean your mouth by brushing your teeth in the morning and evening, rinsing your mouth after meals, using dental floss, etc. to avoid food impaction; avoid hitting or pulling the all-ceramic teeth.
2. Precautions for medication: Patients with gingivitis can use antibiotics under the guidance of a doctor to eliminate local inflammation.
3. Dietary precautions: In your daily diet, you should reduce the intake of foods that are too hard, sticky, too cold or too hot.
4. Follow-up examination: Follow the doctor’s instructions for follow-up examination after the operation to understand the condition of the oral cavity and teeth in time; you can go to the hospital regularly for cleaning to remove dental plaque and tartar.
Preoperative precautions
1. Before getting all-ceramic teeth, have good communication between doctors and patients, understand the complete treatment process, costs and risks, and be fully prepared mentally.
2. Clean your mouth before the operation, and it is best to have a teeth cleaning.
3. People with periodontal disease need to undergo periodontal treatment first.
4. Patients with pulp or apical diseases need to complete root canal treatment before undergoing all-ceramic tooth treatment.
5. Patients with malocclusion need to undergo orthodontic treatment first, and then undergo all-ceramic crown restoration after a good occlusal relationship is restored.
6. Young permanent teeth and those with high pulp horns and easy pulp exposure need to pay special attention to the protection of the pulp.
Surgical Procedure
The operation of all-ceramic teeth mainly includes anesthesia, grinding of tooth tissue, casting models, trying on temporary crowns and all-ceramic teeth, and bonding.
