Computer Guided Implantology Accuracy and Complications

Abstract EN

The computer-based method allows the computerized planning of a surgical implantology procedure, using computed tomography (CT) of the maxillary bones and prosthesis.

This procedure, however, is not error-free, unless the operator has been well trained and strictly follows the protocol.

A 70-year-old woman whom was edentulous asked for a lower jaw implant-supported prosthesis.

A computer-guided surgery was planned with an immediate loading according to the NobelGuide technique.

However, prior to surgery, new dentures were constructed to adjust the vertical dimension.

An interim screwed metal-resin prosthesis was delivered just after the surgery; however, after only two weeks, it was removed because of a complication.

Finally, a screwed implant bridge was delivered.

The computer guided surgery is a useful procedure when based on an accurate 3D CT-based image data and an implant planning software which minimizes errors.
