The purpose of this investigation is an exact preoperative 3D-localisation of impacted and supernumerary teeth in the maxilla using Cone Beam Computer Tomography
An exact localisation of impacted teeth is often difficult to assume by using conventional radiological techniques like OPT or dental films. In contrast to these two-dimensional imaging methods the Cone Beam Computer Tomography (CBCT) respectively the Digital Volume Tomography (DVT) offers a three-dimensional imaging of the maxillofacial region, providing the opportunity to study objectives in all standard plans with 3D-reconstruction in multisection views.
A preoperative radiological investigation using CBCT on patients who are supposed to undergo surgery for impacted and supernumerary in the frontal maxilla shall clarify the certainty and safeness of this 3D-imaging method. Therefore a comparison between the findings on the CBCT, on eventually former conventional x-rays and the intraoperative finding as gold standard is done.

A tooth that is prevented from erupting by a physical barrier, usually other teeth. Impaction may also result from orientation of the tooth in an other than vertical position in the periodontal structures.
The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).
The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.
The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.
Volume of circulating BLOOD. It is the sum of the PLASMA VOLUME and ERYTHROCYTE VOLUME.
