Partial Dentures: Their types, advantages and disadvantages

What are partial dentures?

Partial dentures are a blessing for people who want to replace missing, broken or cavity-filled teeth. Dentures have been used since 2500BC, and they have been made with animal teeth, wood, porcelain, etc. The dentures of today are far more advanced and forged from cast metal, polymer and resin. Partial dentures are natural looking, and they come in various types.

There are many factors that determine what kind of partial denture will suit your requirement. A dental prosthetist will take the following criteria into account:

  • Oral health
  • Structure of the teeth
  • Support of the remaining teeth
  • Budget
  • Appearance, grip and stability.
  • Allergic reactions

Types of partial dentures :

1.Cast metal partial denture

A cast metal partial denture is made with ultra chromium cobalt alloy. It is highly robust and suitable for long term wear and tear. Cast metal partial dentures are mostly preferred for its lightweight material that causes minimal discomfort and interference while eating or talking. These partial dentures come with rest seats or clasps which allow the appliance to fit snugly over the area.

But these metal clasps are not always advantageous for the user. They may cause allergic reactions in some people. Despite being quite expensive, the metal clasps are not a suitable choice for people who lack the motor skills to use this partial denture. The fabrication of the cast metal partial denture is also a time-consuming process.

2.Flexible partial denture

Flexible partial dentures fulfill two requirements: they effectively replace one or more missing teeth, and they are a better choice for those who are allergic to the metal casts used in cast metal partial dentures. Flexible dentures are aesthetic, odour and stain-resistant, impact-resistant, and easy to fix.

However, the prolonged use of flexible partial dentures can cause the build of plaque and bacteria. Despite their high cost, they do not offer the flexibility of redoing denture relines and rebases.

3.Acrylic partial dentures

Otherwise known as dental flipper, acrylic partial dentures are bulky and uncomfortable for long-term use. Most dentists use acrylic dentures as a temporary solution while waiting for permanent dentures such as cast metal dentures. Unlike flexible dentures, acrylic dentures can be relined and repaired with ease. Fabrication is faster and cost-effective.

The down side of acrylic partial dentures is that they are vulnerable to damage, which is why they are fabricated to be bulky to withstand impact. This bulky fixture covers a large part of the mouth causing gagging, discomfort and a weakened sense of feel and taste.

If you are using partial dentures, never neglect your oral hygiene and care. The dentures must be removed every night to allow the gums to “breathe” and to facilitate blood circulation. Flossing is important and so is brushing, because it is imperative to prevent the growth of plaque. A regular dental checkup is also crucial.
