Bone resorption is the process by which people lose bone mass. It happens to astronauts, the elderly, and especially denture wearers.

Bone resorption in your jaw can make it so you don’t have enough bone to support dentures, and may cause a fracture in your jaw. If you understand bone resorption, you can work to prevent it and protect your bones.

What Causes Bone Resorption?

We think our bones have stopped growing once we reach a certain age, but they haven’t. Although our bones aren’t getting bigger, they’re growing constantly to respond to our body’s needs.

Your body removes bone tissue, and it replaces it. This keeps your bones healthy and strong. It also allows your bones to change in response to stress. Your body will add bone mass where it’s needed, and take it away from where it’s not.

Bone resorption is when the process of removing bone goes faster than the process of replacing it. Sometimes, your body is doing this because it needs calcium, so it’s raiding the stocks of calcium in your bones. Other times, you may have a disease or condition that speeds up the process of bone removal. It can also occur in places where a lack of stimulation makes your body think that bone mass isn’t necessary.

This process also changes with age, so that your body tends to create less bone as we get older.

Bone Resorption and Dentures

Your teeth play an important role in stimulating your jawbone so your body tries to maintain bone mass there. Once your teeth are lost, your body may begin removing the bones that used to support them.

As your bones are removed, the alveolar ridge, the bone that used to support your teeth and now supports your dentures, shrinks down and moves inward, which can contribute to the aged, sunken appearance that people have when they wear dentures. It can also cause your dentures not to fit. Sometimes, resorption happens so fast that you may need to have your dentures refitted in less than a year.

FOY® Dentures and Resorption

FOY® Dentures are designed to overcome weaknesses of traditional dentures that encourage bone resorption. This includes:

  • Giving even force to better stimulate the jawbone. It’s not the same as your teeth or dental implants, but it’s better than traditional dentures.

  • Encouraging you to chew more with better fit and function. The more you use your jaws, the more likely they’ll be retained.

  • Improving nutrition by allowing you to eat more foods. If you continue to eat a balanced diet, your body may feel less need to raid your bones generally, including your jawbone.

During your consultation, your local dentist can talk about this and other benefits of FOY® Dentures.
