Cosmetic Dentistry Technology Dental Bone Replacement

Over time, everything breaks down. Our bones are no exception. As teeth are removed or fall out, the bone is no longer used, resulting in a weakened jaw and bone loss. This makes it difficult to smile, chew and do other things we often take for granted. Fortunately, with modern dental technologies, there are multiple ways to replace teeth and bone to prevent bone loss and keep mouths stronger and healthier longer.

Bone Replacement Techniques

Bone replacement procedures can be used to facilitate the replacement any number of missing teeth. There are several bone replacement procedures, including:

  • bone expansion/widening
  • extension socket bone replacement and preservation
  • major bone grafting
  • nerve repositioning
  • ridge augmentation.

Types of Bone Grafting Procedures

If you want to replace missing teeth you will need to insert dental implants. If there has already been significant bone loss, it may be necessary to have a bone graft (sometimes mistakenly called a “bone graph”).

A bone graft adds bone material to the jawbone so the implant will bond to the bone and be stabilized. There are four types of bone grafts, including:

  • allografts that use tested, sterilized bone taken from cadavers
  • alloplastic that uses a man-made synthetic substance that mimics natural bone
  • autografts that use bone from other parts of your own body
  • xenografts that use processed bone taken from animals.

Generally, autografts are the best procedures for bone replacement because they use your own bone material, which your body recognizes and can easily transform into the bone you need.

Allografts and xenografts can also turn into natural bone, but the testing to find a match is time-consuming and doesn’t always work. Alloplastic bone grafts won’t necessarily replace the bone, so some people are hesitant to use it in place of the other, naturally occurring options.

Dental Implants and Bone Loss

Bone loss begins the moment a tooth is removed. The best way to prevent bone loss is to replace the bone and insert a dental implant immediately. Dental implants are the most effective way of preventing bone loss because they use the bones that build muscle and give the bone no chance to disintegrate.

Although bridges can also replace missing teeth, implants are a less-invasive bone replacement procedure. Bridges generally harm the neighboring teeth as they are inserted and then require the other teeth to support them, often resulting in root canals. On the other hand, implants are inserted beneath the gum line, without disturbing other teeth. Dental implants then fuse with the bone, keeping the bone strong and preventing further bone loss.

Advantages and Disadvantages of Dental Implants

Implants are just as easy to clean as your natural teeth and are minimally invasive, meaning they don’t rely on the other teeth, like natural teeth. In short, implants mimic your natural teeth in the way they look, feel and work.

However, the dental implant process can be expensive, especially if bone grafts are necessary. Just like bridges, these bone replacement techniques are not completely effective and may need to be performed more than once to find a match that works.
