What Is a Cast Metal Partial Denture?
A cast metal partial denture is a set of artificial teeth fixed on a removable base that resembles gum tissue. It is made up of metal and acrylic resin.
A cast metal partial denture replaces missing teeth and is fitted with the remaining teeth using metal clasps. The treatment has been popular among dental patients for decades.
The cast metal framework makes the denture stable in the mouth because it is connected to strong and real teeth.
Each cast partial denture is manufactured to custom-fit your natural teeth and gum. Compared to an acrylic denture, it is meant to last longer.
Pros of Cast Metal Partial Dentures
Here are some benefits of getting a cast partial denture. They:
- Offer good distribution of biting stress
- Denture bases’ movement delivers massaging effect to the underlying bone and soft tissue
- Do not affect gum tissue much
- Prevent the remaining teeth from moving
- Offer less direct retention vs. standard acrylic denture
- Regulate the bite, resulting in a relaxed smile
Cons of Cast Metal Partial Dentures
Before asking for a cast partial denture, keep in mind that they:
- Do not provide the most natural aesthetic
- Have a long fabrication process
- May shrink during the casting process. Cobalt chromium, for example, has an average casting shrinkage of 2.3%.
- Require highly efficient lab technicians. One laboratory may produce better results than another under similar conditions.
- Are pricey
Indications of Cast Metal Partial Dentures
You may be eligible for cast metal partial dentures if you have the following:
- Multiple tooth loss
- Absence of teeth behind the blank space
- Good gum health of the remaining teeth
- Jaw bone trauma
The Process of Getting Metal Cast Partial Dentures
Each cast partial denture is unique to the patient, hence a long production period. A patient must see the dentist quite a few times before getting their final cast partial dentures.
It’s fair to assume that every dentist will have some deviations from our timeline below, but if you are a patient interested in getting a metal cast partial denture, here’s what you might encounter:
First Session
The dentist will assess if you are a good candidate for cast partial dentures.
They will take impressions of both your upper and lower dental arches if you are. Study models are created from these impressions.
The unique design of each cast partial denture is made on these models.
Second Session
Next, the dentist will carry out a mouth preparation. To ensure that the final cast partial dentures are stable, they will change the shape of some of your teeth.
After mouth preparation, they will take your final dental impressions to create master models.
Then, a dental technician will manufacture the metal framework of your cast partial denture at a dental laboratory.
Third Session
The cast partial dentures’ metal framework will be inspected on your third appointment. How it fits and remains in the patient’s mouth will determine if adjustments must be made.
Bite registration (or bite impression/occlusion) will be taken to set the teeth up correctly.
The dentist will then choose a color for the artificial teeth based on your natural teeth.
The manufactured teeth will be placed on trial dentures following your bite.
Fourth Session
Now, trial dentures will be tested in the patient’s mouth.
This try-in will reveal if you have problems with any of its features: how it fits, retains, stabilizes, or the way it makes you sound or look.
The laboratory will modify relevant aspects based on the trial’s results and create the final version of your cast partial denture.
Fifth Session
Finally, the dentist can install the final cast partial dentures in your mouth.
Any issues with this version’s features will be inspected and fixed accordingly. Your bite should also receive the same attention.
Be sure to follow the care instructions for your cast partial dentures.
Sixth Session
A dentist requires a denture review from you a week after denture insertion.
The dentist fixes any discomfort your cast partial denture causes in your mouth. You may need several dental visits before getting the perfect fit.
Alternatives to Cast Partial Dentures
If removable partial dentures with a metal framework aren’t appealing, you may look at other dentures.
Consider acrylic dentures or flexible partial dentures as solutions for loss of teeth.
Acrylic dentures
Acrylic dentures are a more transitory type of dentures. They are not seriously durable but are great for use while waiting for a permanent dental restoration.
Flexible partial dentures
Flexible partial dentures are a good option for those with healthier gums than teeth because they put less pressure on the teeth. These dentures are also known as Valplasts.
