Porcelain vs. Acrylic Teeth

Acrylic teeth or porcelain teeth

Today, dentures are generally made with either Porcelain or Acrylic teeth.

Which teeth are the best for you? Do Porcelain or Acrylic teeth last longer? Which teeth are more ideal for dentures? Which teeth are stronger? What is the main difference between Porcelain and Acrylic teeth? These are all common questions that we hear from patients that we will be addressing in this article.

In order to assess denture teeth, we generally rate them based on the following criteria:
Health : The health of our patients is our primary objective. Denture teeth should not put unnecessary force on the surrounding oral tissues or bone.

Appearance : Denture teeth should look natural. We look for a natural shape, color, translucency and dimension.

Bonding : 33% of denture repairs are the result of debonding of teeth according to recent estimates. The teeth and the denture base must be compatible with each other.

Strength: Teeth should resist chipping, staining and fracturing.

Comfort: Teeth should be comfortable. A strong material is preferred but the weight also plays a major consideration.

The table below summarizes the main advantage and disadvantage of Porcelain vs. Acrylic denture teeth: 

 

 

              Porcelain Teeth                         Acrylic Teeth               
 Health  Chewing puts pressure on your dentures. The force is then transferred to the bone underneath your gums. Porcelain teeth are more dense and heavier. The negative aspect of this is that porcelain teeth absorb less forces. Porcelain transfers that force with greater intensity which can accelerate bone loss.  Acrylic teeth transfer less pressure to the gums and bone. As a result, acrylic teeth do not accelerate bone loss in the same way that porcelain teeth do. Acrylic teeth also transfers less pressure from habits such as grinding, clenching or tapping teeth.
 Appearance  Both porcelain and acrylic denture teeth come in a variety of shape, color, translucency and dimension.  Both porcelain and acrylic denture teeth come in a variety of shape, color, translucency and dimension.
 Bonding   Porcelain does not chemically bond to the denture base as the denture base is made out of acrylic, not porcelain.  Acrylic teeth chemically bond to the denture base and are made of the same material.
 Strength  Porcelain teeth are brittle and are more likely to fracture.   Acrylic teeth are less likely to fracture and resist chipping. High quality acrylic teeth also are lesssusceptible to staining.
 Comfort  Patients often advise us that porcelain teeth are “Noisy” and they can hear “clicking sounds” when they bite down on their dentures while chewing. Acrylic teeth do not “click” and patients generally have a more positive experience with them. Dentures with Acrylic teeth are also lighter, making it easier to speak and keep your dentures firmly in place.

 

In conclusion, we highly recommend acrylic teeth. Acrylic teeth are healthier for the patient, look great, chemically bond to the denture base, and are strong and comfortable.
