CT — computed tomography for dental implants

Computed tomography (CT) added a further, more precise imaging technique to the field.

With the development of computed tomography (CT), a further and more precise imaging technique is now available. Computed tomography is an imaging method in which a computer-based analysis combines a large number of individual digital X-ray images into a realistic picture.

A CT scan is made when an X-ray does not provide the required information about the bone situation. Highly developed scanners and CT images then make it possible to measure the bone available and to analyse bone quality through density measurements. They allow anatomical structures to be shown spatially, without distortion and to exact scale, reproducing the smallest details. The position and course of the finest structures, such as nerves, can be traced with spatial precision.

A great advantage are the cross-sectional images a tomogram provides. On these sections the height and width of the bone can be measured directly. Combining the sections produces a three-dimensional image. This three-dimensional picture of the jaw allows a very accurate diagnosis and precise planning of the implant placement.

Answered briefly

Frequently asked questions

When is a computed tomography scan taken before an implant?

A computed tomography (CT) scan is produced when a radiograph does not supply the desired information about the bone situation. In this imaging method many individual digital radiographs are combined by computer into a realistic image.

Can it be measured in advance how solid the jawbone is?

Highly developed computed tomography scanners make it possible to measure the amount of bone available and to analyse bone quality through density measurements. The image is free of distortion and metrically exact, so that the position and course of even the finest structures such as nerves can be followed precisely in three dimensions.

What are the slice images of a tomography scan?

Slice images are individual sectional images of the jaw, on which the height and width of the bone can be measured directly. Combining the slice images produces a three-dimensional image of the jaw that allows a very precise diagnosis and exact planning of the implant position.
