Plastic Dentures or Metallic Dentures?

Plastic vs Metal DenturesTeeth are nature’s gift to us. They make it easy for us to eat and talk, and they also provide us with our smile. By practicing proper oral hygiene, a lot of people are going to keep most of their natural teeth for life. However, a lot of adults lose several or even majority of their teeth as they become older due to a variety of reasons. In some cases, it is because people fail to observe proper oral hygiene and very rarely do they see a dentist. The moment you lose your teeth, they can no longer grow back. On the other hand, innovations in dentistry actually help people to recover their eating, smiling, and smiling functions. You can be fitted with artificial teeth in the form of bridges, if not dentures. Dentures offer a suitable solution for people who have lost most of the natural teeth they have, or if those that are left behind are in a very bad shape that they need to be removed. We are proud to offer our esteemed patients perfect fitting and dentures that are lifelike.

 

Dentures – What are They

Dentures are a set of artificial teeth with a base that attaches to the gum. These artificial teeth come in either porcelain or acrylic (plastic) material. The color of the teeth resembles the remaining natural ones inside your mouth while the base is gum colored, so that the prosthetics will look much more appealing. Learn more about dentures here.

 

Preparation of the Dentures

Partial Dentures RemovalBefore taking molds for the gums and teeth, any as well as all the rest of the dental process is first completed. If it is a complete set of dentures you are getting, then all of the remaining teeth will have to be extracted and the gum must be allowed to heal, if possible.

For a different variation known as overdenture, the remaining teeth may not be extracted but are rather crushed down to stubs near the flesh of the gums. If a number of teeth become useless, these are then completely extracted. Several teeth that are intended to support the denture are crowned otherwise.

 

Denture Types

Dentures are classified according to the material that the base is made of as well as the number of teeth the denture has, which can be either full or partial.

  • Partial Denture – Whenever a number of the existing natural teeth remain healthy, these teeth are retained. They are likewise used to provide support for the denture, meaning that the wings of the dentures are going to rely on these teeth for support.
  • Full Denture – This type of denture is only resorted to if all of the natural teeth have been extracted, or else already gone. If the number of missing teeth is between 24 and 28, then it is already sufficient to get a full mouth. For a full denture, every remaining tooth is extracted from the jaw. In a different setup known as the overdenture, the teeth left behind are instead grinded down close to gum level.

 

The Various Types of Denture Materials Available

When going for dentures, you will have to ask yourself another question. Dentures are categorized according to the material that the base is made of. The teeth can come in either porcelain or acrylic. The materials for the base are also of two types, depending on which one you prefer:

  • Metallic alloys
  • Acrylic (otherwise, plastic)

 

Metal-based dentures

To simply call them metal dentures is technically wrong but widely used. It is exclusively the base that is metallic. Metal based dentures are available in two types.

  • Standard Metal-Based Dentures – The metal base of this type of dentures directly touches the gum tissue. The base, therefore, must be hypoallergenic and of biocompatible medical grade alloy in order not to hurt the tissue it comes into contact with.
  • Modified Metal-Based Denture – A liner made of hard or soft plastic isolates the metal base from the underlying tissue supporting it. The soft liner is typically chosen over the hard plastic variety because most wearers find it more comfortable. However, the soft liner must be replaced year after year.

 

Metal-based Materials

The material that we are using to manufacture the base explains the great difference. The two types come with advantages as well as disadvantages. Thus, how can you identify which material is best to be used for the base of the new denture you are getting? You have to be aware of all the matters concerning each specific case.

Advantages of Metal-Based Dentures

  • Very strong and durable.
  • Simple to reline.
  • Add strength to the otherwise very fragile narrow dentures.
  • Occasionally, dentures must be narrow in order not to disturb the muscles. Narrow metallic dentures are also available.
  • Help prevent surgical procedures to reposition the frenum.
  • Feel more natural to the user because they are lighter compared to the plastic variety.
  • Dimensionally stable in comparison to a plastic base.

 

Disadvantages of Metal-Based Dentures

  • Cost – The metal-based dentures cost a lot more to manufacture than the plastic ones.
  • Relining – With the standard metal-based dentures, relining is generally much more difficult than the modified metal-based ones.

 

Plastic-based Dentures

A plastic-based denture is absolutely made of plastic, with the exception of the clasp wire or added wings at the tip.  While dentures are typically rigid structures, newer techniques presently enable the dentist to offer you one with a flexible plastic base.

Benefits of plastic dentures

  • Cost – Plastic dentures are less expensive to make.
  • Easier Fabrication Process – They are easier to fabricate.
  • Preferred Choice – If immediate dentures are what you need, this would be your best option.

 

Downsides of plastic dentures

  • Fragility – These plastic dentures happen to be fragile.
  • Stability – They might shrink and relining then becomes necessary.
  • Gum Damage – They can be irritating to the gum.
  • Soaking – They have to be put in a soaking solution when removed.

 

Types of Special Dentures that we Offer

We have two special types of denture to offer:

  • Overdentures
  • Immediate dentures

Immediate (plastic) dentures can be made right after tooth extraction and are cost-effective. They are worn usually for a few months until the permanent ones are returned by the lab and while waiting for the gums to heal. This type of denture is sometimes referred to as ‘flipper’ dentures.

 

Overdentures

Overdentures are a unique type of full dentures. With the normal full dentures, the existing teeth that are healthy must be extracted. Sometimes, it is probably better to keep these teeth and instead file them down to leave stubs within the gum for the denture to sit on. Overdentures are regarded as more advantageous for the lower jaw.

Why Overdentures May be Unsuitable

Overdentures may not be suitable in these cases:

  • Improper Oral Hygiene – The remaining roots or stubs must always be very clean. If a patient   seems unable to observe proper oral hygiene, an overdenture is unlikely to be recommended.
  • Excessive Decay – If a patient is prone to uncommon tooth decay, this could lead to the roots decaying away really fast.
  • Loose Teeth – Loose teeth are probably unable to handle the chewing load.
  • Location – If roots are located where they are not able to take part in the chewing load.
  • Unsuitable Shape – If it is not possible to file the roots to the right shape.

 

Benefits of Overdentures

Overdentures come with several benefits.  A few are enumerated below.

  • Part of the chewing force is shared with the natural teeth, which the gum would have taken otherwise.
  • They are going to become more stable because of these teeth.
  • Retaining the teeth will prevent resorption of the bone into the sockets.
  • These will keep the facial contours from shrinking.
  • The teeth has a natural to it since some of the pressure are passed on to the jaw bone.

 

Issues with Overdentures:

  • Not suitable in a number of cases.
  • Getting the remaining teeth ready such as root canal and grinding down.
  • Higher cost.
  • Accurate fit is likely to be more difficult.
