+What’s a partial denture?
A partial denture is a dental prosthetic that is used to replace some, but not all of the teeth on one jaw. If all teeth are missing on one jaw, then the prescribed denture is a complete, or full denture.
+What are the different types of partial dentures?
There are generally three types of partial dentures: cast partials, acrylic partials, and flexible partials. Cast partials and acrylic partials have clasps that can be adjusted where flexible partials’ clasps generally can’t be tightened or loosened.
+What are cast metal partial dentures?
Cast metal partials are the time-tested most reliable type of partial. They get their name from the cast, metal frame that sits within the pink denture acrylic.
Pros and cons of cast parital dentures
The advantage of this type of denture is that the metal frame is created as a casting using a replica model of the mouth. This means that the metal hugs every contour of the mouth and helps ensure that the final denture will fit as closely as possible to the oral anatomy.
+Are cast metal partials safe?
The metal used to make the casting, or metal part of partials is mostly chrome and cobalt and it’s very rare that anyone has any sort of allergic reaction to these metals. Many patients also ask whether having metal in their mouth will directly cause health problems. The chrome/cobalt metals that we use in cast partials don’t carry the same toxic reputation and controversy that mercury amalgam fillings do. However, there are alternative options for partial dentures for those who prefer not have metal in their mouth, such as flexibile partials, or acrylic partial dentures.
+What are acrylic partial dentures?
Acrylic partial dentures are similar in design to complete dentures whereby the missing teeth are replaced by denture teeth which are supported by a 2 mm thick denture base. These dentures are held in place by wire that is bent around some of the remaining natural teeth.
Pros and cons of acrylic partial dentures
Acrylic partial dentures generally don’t fit as well as cast partials because they are considerably thicker and don’t have a rest on top of the natural teeth to prevent them from sinking into the gums. Sometimes, acrylic partial dentures can cause more harm than good because the continuous up and down movement of the denture can push away the gum around a natural tooth, increasing the chances that it will need to be extracted.
+What are flexible partial dentures?
Flexible partial dentures are somewhat new to the denture scene compared to cast and acrylic partials. There are two types of flexible partials that we use at The Denture Centre. The first is a vinyl material that is used in place of the pink denture acrylic.
Why choose flexible partial dentures?
The vinyl is flexible and allows us to make the partial without any metal clasps. Many people don’t like the idea of seeing metal clasps on their own teeth when they smile so vinyl, flexible dentures avoid this issue.
Pros and cons of flexible partial dentures
The vinyl material is thicker than the
casting and is bulkier in the mouth. The vinyl clasps
that sit just below the natural teeth cannot be tightened or loosened
like they can in cast and acrylic dentures. The second type of
flexible denture consists of a clear flexible cast frame instead of
the metal one in a cast partial.
+What materials are used to construct cast partial dentures?
The casting material is chrome and cobalt. We exclusively use Vitallium® 2000 because of its extraordinary strength, fracture resistance, and lighter weight.
+What type of partial denture is best?
In general, cast partial dentures are the time tested, most reliable type of partial denture. They are usually the best choice because of the fact that we can bend the clasps that hook on to the remaining natural teeth, making the denture tighter or looser. Cast partials also fit better and are lighter in weight than acrylic partial dentures.
+What’s a flipper denture?
A flipper denture is similar in design to an acrylic partial
denture but only for when missing front teeth.
