A denture is a detachable plate or frame that replaces missing teeth by retaining artificial teeth. Cast partial dentures are for people over the age of 65 who have multiple teeth missing. These dentures can be removed and fixed by the patient.

Removable partial dentures with cast metal frameworks have several advantages over the more regularly used partial dentures. These dentures’ frameworks are custom-made to match the teeth. They are remarkably stable and retentive because they sit on the teeth and are connected to them.

Continue reading this article to learn about cast partial dentures, their fabrication, advantages, disadvantages, and more.

First, let’s know,

What exactly is Cast Partial Denture (CPD)?

Cast partial denture is a type of partial denture comprising a cast metal framework with acrylic resin prosthetic teeth. Traditional acrylic partial dentures are less durable, retentive, and stronger than cast partial dentures.

Indications for Cast Partial Denture

• Loss of multiple teeth.
• No teeth behind the edentulous area.
• Remaining teeth’ periodontal (gum) health is excellent.
• Injury to the jaw bone.
• When lateral and anterior-posterior forces have to be resisted, the remaining teeth need stabilization.

Let’s discuss,

Steps Involved in Fabrication of Cast Partial Denture

The patient will require several appointments for the final placement of a cast partial denture. Individual dental conditions decide the design and fabrication of each denture. The following are some of the steps the patient might expect during the dental visits for cast partial denture:

First visit

1. The dentist will take impressions of both the upper and lower dental arches.
2. The study models are made. On the study models, cast partial dentures are designed uniquely.

Second visit

1. The dentist will perform a process known as mouth preparation. Mouth preparation entails changing the contour of some teeth so that the final cast partial denture may be retained and stabilized.
2. After mouth preparation, the dentist will take the final dental impressions and make the master models.
3. A dental technician in the dental laboratory designs and fabricates the metal framework of a cast partial denture.

Third visit

1. The metal framework of a cast partial denture is tested for fit and retention in the patient’s mouth. For improved fit and retention, the metal structure may need to be adjusted slightly.
2. The dentist will take a bite/occlusion impression of the patient. Bite registration is the term for this practice.
3. The dentist will next choose the colour of the artificial teeth based on the patient’s natural teeth.
4. A dental technician will place the artificial teeth on the trial dentures based on the patient’s bite/occlusion.

Fourth visit

1. The dentist will take a trial of the dentures in the mouth of the patient.
2. The trial denture’s fit, stability, retention, phonetics, and aesthetics are tested and changed accordingly.
3. After the try-in, the trial dentures are shipped to the dental laboratory to fabricate final cast partial dentures.

Fifth visit

1. The dentist places the final cast partial dentures in the patient’s mouth.
2. The final cast partial dentures’ fit, stability, retention, phonetics, and aesthetic are all checked and corrected as needed.
3. The dentist examines the patient’s occlusion/bite and makes necessary adjustments.
4. The dentist gives instructions to the patient on how to care for their dentures properly.

Sixth visit

1. The dentist calls the patient for a denture review one week after denture insertion.
2. The dentist will ask the patient if the dentures are causing any problems such as discomfort, pain, or ulcers.
3. The cast partial dentures’ fit, stability, retention, phonetics, and aesthetic are all examined and corrected as needed.
4. The dentist examines the patient’s occlusion/bite and modifies it as necessary.

If the patient’s cast partial denture is causing them any problems, they should tell their dentist and schedule an appointment for a check-up.

Advantages of Cast Partial Denture

• Tissue alteration is kept to a minimum.
• Requires less relining or rebasing of the denture.
• The occlusal (biting stress) distribution is good.
• The movement of the denture bases massages the underlying bone and soft tissue.
• Compared to a traditional acrylic denture, it requires minimum direct retention.
• Regulates the occlusion.
• Supports the lips and cheeks.
• Reduces the tipping tension on the teeth.
• Prevents shifting of the teeth.

Disadvantages of Cast Partial Denture

• The use of a cast metal framework makes a cast partial denture hefty and inconvenient for the patient.
• It is hard to repair.
• It is delicate.
• The fabrication process is complicated.
• It requires more dental visits and takes longer to fabricate.
• Expensive
• Inability to protect against detrimental lateral loads.
• It necessitates regular maintenance.
• Aesthetically, it’s not appealing.

Now, let’s know the,

Alternatives to Casting Partial Dentures

• Acrylic Denture

Each treatment method has its own set of benefits and drawbacks. Hence, it is critical to consult with your dentist to choose the best treatment option for you.

Natural teeth are always superior to artificial teeth in terms of performance. Thus, it is critical to avoid tooth loss in the first place by practicing good oral hygiene regularly. Daily tooth brushing, flossing, mouthwash, tongue cleansing, and regular dental appointments can help maintain good oral health. Always keep in mind that good dental health can lead to better overall health.
