Name of the Procedure:

Common name(s): Pin Retention-Per Tooth
Technical/Medical term: D2951

Summary

Pin retention-per tooth involves placing a small metallic pin in the tooth to add structural support for a dental restoration, such as a filling or crown. This procedure is typically performed when there isn't enough tooth structure remaining to hold a restorative material securely.

Purpose

Pin retention is usually necessary when significant decay or damage has left minimal tooth structure to work with. The primary goal is to provide a stable foundation to support a filling or crown, thereby reinforcing the tooth and improving the longevity of the restoration.

Indications

• Severe tooth decay that compromises the tooth's structural integrity
• Broken or heavily worn teeth
• Teeth requiring extensive restoration work
• Insufficient natural tooth structure to support a filling or crown

Preparation

• No special fasting is required.
• Patients may be asked to refrain from certain medications, particularly blood thinners, with their physician’s guidance.
• A thorough dental examination and imaging (X-rays) to assess the extent of damage and plan the procedure.

Procedure Description

1. Anesthesia: Local anesthesia is administered to numb the area.
2. Access: The dentist will remove decayed tissue and shape the cavity for the pin.
3. Pin Placement: A small hole is drilled into the tooth structure, and a metallic pin is placed.
4. Restoration: Composite material or another restorative compound is applied around the pin to complete the filling or foundation for a crown.
5. Finishing: The restoration is shaped and polished for proper bite alignment and aesthetics.

Tools/Equipment: Dental drill, metallic pins, composite materials
Anesthesia: Local anesthesia

Duration

The procedure typically takes about 30 to 60 minutes, depending on the complexity and number of pins required.

Setting

Pin retention per tooth is usually performed in a dental office or clinic.

Personnel

• Dentist
• Dental assistant

Risks and Complications

• Common Risks: Temporary sensitivity, mild discomfort
• Rare Risks: Infection, pin displacement, damage to adjacent teeth or gums

Benefits

• Provides structural support to severely damaged or decayed teeth
• Enhances the durability of the restoration (fillings or crowns)
• Immediate improvement in tooth function and aesthetics

Recovery

• Patients may experience minor numbness for a few hours post-procedure.
• Avoid eating hard or sticky foods for a few days.
• Follow-up appointment may be needed to ensure the restoration is firmly in place.
• Normal activities can typically be resumed the same day.

Alternatives

• Onlays or Inlays: For less extensive damage, these indirect restorations might suffice.
• Crowns: Full coverage of the tooth, though more extensive
• Tooth Extraction: In cases where the tooth cannot be preserved.

Pros and Cons of Alternatives:

• Onlays/Inlays: Less invasive but may not be sufficient for extensive damage
• Crowns: More protective but also more costly and time-consuming
• Extraction: May be the last resort but removes the tooth entirely, necessitating replacements like implants or bridges

Patient Experience

During the procedure, patients typically feel no pain due to local anesthesia but may experience vibration and pressure. Post-procedure, mild discomfort or sensitivity is normal and can be managed with over-the-counter pain medication, if necessary. Most patients can return to their normal activities immediately, with minor dietary adjustments.
