Dental Code D6194: Abutment supported retainer crown for FPD – titanium and titanium alloys

Dental Code D6194 refers to the procedure known as an abutment supported retainer crown for a fixed partial denture (FPD) using titanium and titanium alloys. This code specifically addresses the use of these materials in the construction of the retainer crown, which plays a crucial role in supporting and anchoring the FPD. 

Dental Code D6194 signifies the fabrication and placement of an abutment supported retainer crown for a fixed partial denture using titanium and titanium alloys. A fixed partial denture, also known as a dental bridge, is a prosthetic device used to replace missing teeth. It consists of artificial teeth that are anchored to natural teeth or dental implants adjacent to the gap. The retainer crown serves as the attachment point for the FPD, providing stability and support.

The first step in the process is a comprehensive examination of the patient's oral health, including a review of their medical history. The dentist will evaluate the condition of the abutment teeth, which will support the FPD, and assess the suitability of using titanium or titanium alloys for the retainer crown. Treatment planning involves determining the number of abutment teeth required, the type of FPD, and the design of the retainer crown.

Once the treatment plan is established, the next step involves the preparation of the abutment teeth. The dentist will carefully shape and contour the abutment teeth to create space for the retainer crown. This process may involve removing a small amount of enamel from the outer surface of the teeth to ensure a proper fit. The dentist will also take impressions of the prepared teeth to fabricate the retainer crown accurately.

After tooth preparation, temporary restorations are placed on the abutment teeth to protect them while the final retainer crown is being fabricated in the dental laboratory. These temporary restorations help maintain the proper alignment of the teeth and provide functional and aesthetic benefits during the interim period. Additionally, temporary restorations also assist in evaluating the fit, function, and aesthetics of the planned final retainer crown before its permanent placement.

In this step, the dentist takes detailed impressions of the prepared abutment teeth and the surrounding gums using dental impression materials. These impressions capture the exact shape and contours of the teeth and soft tissues, which are crucial for creating a well-fitting retainer crown. Additionally, the patient's tooth shade is determined to ensure the final restoration matches the natural appearance of the adjacent teeth. The shade selection process involves using shade guides and digital imaging technology to accurately match the color of the retainer crown to the patient's existing teeth for a seamless and natural-looking result.

The impressions are sent to a dental laboratory, where skilled dental technicians use the latest CAD/CAM technology to fabricate the retainer crown. Titanium and titanium alloys are preferred materials due to their biocompatibility, strength, and durability. These materials offer excellent resistance to corrosion and are well-tolerated by the surrounding oral tissues. The dental technician meticulously crafts the crown to achieve an optimal fit, functional occlusion, and proper aesthetics.

Once the retainer crown is fabricated, the temporary restoration is removed, and the abutment teeth are thoroughly cleaned and prepared for the final placement. The dentist carefully checks the fit, contacts, and occlusion of the retainer crown before permanently cementing it onto the abutment teeth. Any necessary adjustments are made to ensure the crown aligns harmoniously with the patient's bite and natural dentition.

After the retainer crown is cemented, the dentist provides instructions on proper oral hygiene and routine dental care. Regular dental check-ups and professional cleanings are essential to maintain the longevity of the restoration. The patient should also adhere to good oral hygiene practices, including brushing, flossing, and using antimicrobial mouth rinses to prevent plaque accumulation and maintain the health of the supporting tissues.

Dental Code D6194 represents the abutment supported retainer crown for a fixed partial denture using titanium and titanium alloys. This procedure involves meticulous planning, tooth preparation, temporary restorations, impression taking, laboratory fabrication, and the final placement of the retainer crown. Titanium and titanium alloys are chosen for their biocompatibility and mechanical properties, ensuring a long-lasting and aesthetically pleasing restoration. Proper post-placement care and maintenance are crucial for the success and longevity of the retainer crown. By following these steps, dental professionals can provide patients with functional and durable fixed partial dentures.
