Kendra James was in for her routine dental examination and Dr. Mendes has found decay under an MOD restoration on tooth #5. After taking x-rays and completing the examination, Dr. Mendes has recommended that the MOD restoration be replaced with a crown. Kendra was concerned about the time involved and the cost of the crown. Dr. Mendes has included the CAD/CAM technology in his office since Kendra’s last appointment. After talking with Kendra the dental assistant found out that Kendra was also concerned about the impressions because she has a gagging problem.
Case Study Review
- What can be explained to Kendra about the time and expense of a crown procedure?
- Discuss the steps involved with the CAD/CAM technology.
- What can the dental assistant do to help Kendra with her gagging concerns?
The Correct Answer and Explanation is :
When discussing the dental crown procedure with Kendra James, it’s important to address her concerns about time and cost.
1. Time and Expense of a Crown Procedure:
The traditional dental crown procedure typically requires two visits:
- First Visit: The dentist examines the tooth, takes impressions, and places a temporary crown.
- Second Visit: The permanent crown is placed after it has been fabricated, which can take a few weeks.
With the introduction of CAD/CAM technology, the process has been streamlined:
- Single Visit: The dentist can prepare the tooth, take digital impressions, design, and fabricate the crown in one appointment, often within a few hours.
Regarding cost, dental crowns vary based on material and location. In the U.S., prices range from $500 to $3,500 per tooth, depending on the type of crown used.
2. Steps Involved with CAD/CAM Technology:
CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) technology enhances the crown fabrication process:
- Data Acquisition: The dentist uses a digital scanner to capture a 3D image of the prepared tooth and surrounding structures.
- Design: The digital model is imported into CAD software, where the dentist designs the crown to fit precisely.
- Fabrication: The design is sent to a milling machine or 3D printer, which creates the crown from materials like ceramic or resin.
- Placement: The dentist checks the fit and adjusts as necessary before permanently bonding the crown to the tooth.
This process reduces the need for temporary crowns and multiple visits.
3. Addressing Gagging Concerns:
For patients like Kendra with a gag reflex, traditional impressions can be challenging. The dental assistant can help by:
- Using Digital Impressions: CAD/CAM technology employs digital scanners that capture 3D images without the need for impression materials, minimizing the risk of gagging.
- Ensuring Comfort: The assistant can provide support and reassurance, allowing Kendra to take breaks if needed during the scanning process.
By utilizing CAD/CAM technology, the dental team can offer a more comfortable and efficient experience for patients with gagging concerns.
