Name of the Procedure:

Amalgam-Three Surfaces (D2160)

Summary

An amalgam three-surface filling is a dental procedure used to restore a tooth that has been damaged by decay. This type of filling involves the use of a silver-colored amalgam, composed of mercury, silver, tin, and copper, which is durable and can withstand significant chewing pressure.

Purpose

Amalgam fillings address dental cavities, particularly in molars and premolars due to their durability. The goal is to restore the function, integrity, and morphology of a damaged tooth, preventing further decay and improving oral health.

Indications

• Visible or diagnosed dental caries affecting three surfaces of a tooth, typically molars or premolars.
• Tooth damage due to fracture or wear.
• Patient preference for a long-lasting and durable filling material.

Preparation

• The patient should brush and floss as usual before the appointment.
• Inform the dentist of any allergies or medical conditions.
• X-rays may be taken to assess the extent of decay.

Procedure Description

1. Anesthesia: Local anesthesia is administered to numb the area around the affected tooth.
2. Decay Removal: The dentist uses a high-speed drill to remove the decayed portions of the tooth.
3. Tooth Preparation: The tooth is shaped to create a space for the amalgam filling.
4. Lining: A liner may be applied to protect the tooth's pulp.
5. Amalgam Placement: The dentist mixes the amalgam and places it in the prepared cavity, packing it tightly to ensure no air bubbles.
6. Shaping: The filling is shaped to restore the tooth’s natural contour.
7. Polishing: The surface of the filling is polished to smooth it out and remove any rough edges.

Duration

The procedure typically takes about 20 to 30 minutes.

Setting

Performed in a dental office or clinic.

Personnel

• Dentist
• Dental assistant

Risks and Complications

• Allergic reactions to amalgam (rare).
• Tooth sensitivity to hot or cold.
• Risk of the filling breaking or dislodging over time.
• Potential for further decay around the filling if oral hygiene is not maintained.

Benefits

• Durable and long-lasting, often lasting 10-15 years or more.
• Effective in restoring function and preventing further decay.
• Less expensive compared to composite fillings.

Recovery

• Avoid eating for the first hour after the procedure.
• Expect some sensitivity for a few days, which should subside.
• Maintain good oral hygiene practices.
• Return for regular dental check-ups to monitor the filling.

Alternatives

• Composite Fillings: Tooth-colored but less durable than amalgam.
• Ceramic Fillings: Durable and aesthetic, but more expensive.
• Gold Fillings: Very durable but expensive and less commonly used.

Patient Experience

During the procedure, patients will feel the effects of the local anesthesia and should not experience pain. There might be slight pressure or vibrations from the dental tools. Post-procedure, some sensitivity and mild discomfort are normal, usually managed with over-the-counter pain relievers.
