Options for Replacing Teeth

Friday, June 25th, 2010

There are several reasons why a patient may decided to have dental implants to replace missing teeth. Most common are:

1. Advanced Periodontal Disease: where many teeth are loose and there is insufficient bone support for these teeth.

2. Gross Caries to Bone Level: When teeth are decayed all the way to the bone and there is no way the teeth can be saved.

3. Large Root Abscesses: The tips of the roots of teeth in bone have been abscess and infected for so long that large bone loss has occurred and it is necessary to extract the teeth.

4. Dentures do not fit well or have poor suction etc.

5. Patient does not like dentures and wants something that is non-removable or fixed.

Cone Beam Computerized Tomography

What is Cone Beam Computerized Tomography (CT)

Similar to a hospital CT scan, a cone beam CT takes a 3 Dimensional image of bones and hard skeletal structures such as teeth.  Essentially its a 3D X-ray.

This is a relevant and important topic for implant dentistry today. When a patient desires a dental implant, there are important considerations in the planning of where the surgeon will place that implant in solid bone.

A 3D X-ray such as a Cone Beam CT will allow for the surgeon to visualize in 3 Dimensional space where they can exactly place the implant. This is extremely important because it allows them to avoid vital structures such as nerves and blood vessels. Also, it helps them to plan for possible grafting necessary when the bone is insufficient to place an implant.

The Cone Beam CT is an excellent diagnostic tool which will enable your surgeon to avoid any complications or pitfalls in your surgery, before he goes into surgery.

The American Dental Associate and California Dental Associate both recommend a Cone Beam CT be taken before any dental implant is placed.
