Introduction

A full mouth of porcelain-fused-to-metal (PFM) crowns, also known as a full set of PFM crowns, involves a fabrication process that includes oral examination and tooth preparation, taking impressions and recording jaw position, fabricating and trying in temporary crowns, fabricating and installing the PFM crowns, and follow-up maintenance and review appointments. If you have any concerns, it is recommended to consult a dental professional in advance. The process of creating a full set of PFM crowns requires cooperation and effort from both the patient and the dentist to ensure that each step achieves the desired therapeutic outcome.

A full mouth of porcelain-fused-to-metal (PFM) crowns, also known as a full set of PFM crowns, involves a fabrication process that includes oral examination and tooth preparation, impression taking and occlusal position recording, temporary crown fabrication and trial placement, PFM crown fabrication and installation, as well as follow-up maintenance and review. If you have any concerns, it is recommended to seek medical advice in advance. The detailed explanation is as follows:

1. Oral examination and tooth preparation: Prior to fabricating a full set of PFM crowns, patients need to undergo a comprehensive oral examination to ensure the stability and health of the abutment teeth, as well as assess the condition of the gums and oral mucosa. Subsequently, the dentist will prepare the teeth by professionally reshaping them to the appropriate form, providing a solid foundation for subsequent PFM crown fabrication.

2. Impression taking and occlusal position recording: After tooth preparation, the dentist will create precise silicone impressions to capture the shape and size of the teeth. At the same time, the jaw position will be recorded to ensure accurate occlusion once the PFM crowns are fabricated. This step is a critical part of the PFM crown fabrication process and directly affects the final accuracy and comfort of the crowns.

3. Temporary crown fabrication and trial placement: During the waiting period for the PFM crowns, the dentist will fabricate temporary crowns to protect oral health and aesthetics. Temporary crowns are usually made of plastic or metal materials and can be worn before the completion of the full set of PFM crowns. Patients will trial the temporary crowns to adapt to the future shape of the PFM crowns.

4. PFM crown fabrication and installation: After approximately one week, once the PFM crowns are completed, patients need to return to the clinic. The dentist will conduct trial fittings and adjustments to ensure the shape, size, color, and occlusal relationships of the crowns meet the requirements. If adjustments are needed, the dentist will remake the PFM crowns until the desired outcome is achieved. Finally, the dentist will cement the fabricated PFM crowns onto the patient's abutment teeth, completing the installation of the full set of PFM crowns.

5. Follow-up maintenance and review: After the installation of the full set of PFM crowns, patients need regular follow-up visits to ensure the crowns remain in good condition. Additionally, maintaining good oral hygiene through regular brushing, flossing, and using mouthwash, as well as avoiding biting hard objects, is important to prolong the lifespan and effectiveness of the PFM crowns.

The fabrication process of a full set of PFM crowns requires cooperation and effort from both the patient and the dentist to ensure each step achieves the desired treatment outcome.

Is it better to get a porcelain crown or a dental implant when a tooth is missing?

In general, "porcelain" refers to porcelain crowns, and "implant" refers to dental implants. When deciding between a porcelain crown and a dental implant for a missing tooth, the choice should be based on the patient's specific circumstances. If a quick restoration is desired, a porcelain crown can be selected; if a more stable and long-lasting restoration is preferred, a dental implant may be chosen. If any discomfort occurs, it is recommended to seek medical attention promptly.

What are the differences between dental implants and porcelain crowns?

Under normal circumstances, the differences between dental implants and porcelain-fused-to-metal (PFM) crowns include variations in restoration methods, tooth stability, effects on adjacent teeth, service life, as well as treatment procedures and duration. It is important to maintain good oral hygiene in daily life, brushing teeth at least twice daily with fluoride toothpaste, and using dental floss or interdental brushes to clean between teeth. Regular dental checkups and professional cleanings are also recommended.
