Third-party software is also available to import and manipulate image data that has been exported in a DICOM format. Third-party software includes Materialise Simplant and Nemotec Dental Systems.
The primary reconstruction of the raw data is completed parallel to the occlusal plane and therefore the occlusal plane is used as the visualization reference plane.
The reconstructions can occur in the axial, coronal, sagittal, curved, and oblique planes.
The location, dimensions and thickness of the reconstructions can be varied to achieve the desired results.
Conventional CT scans take pictures of slices of the body (like slices of bread). These slices are a few millimeters apart. The newer spiral (also called helical) CT scan takes continuous pictures of the body in a rapid spiral motion, so that there are no gaps in the pictures collected.
micro-CT is nondestructive, fast, and allows a fully three-dimensional characterization of the bone structure around the implant
Because of its high resolution, individual trabeculae can be visualized. The accuracy of micro-CT was qualitatively evaluated by comparing histological. Even very close to the interface, the titanium implant does not seem to produce significant artifacts
The technique provided high-resolution consecutive cross-sectional X-ray images of the specimens with a slice-to-slice distance of 4.4 to 11.0 microns.
Tilt of the patients head during the examination is critical because the entire cross sectional images are perpendicular to the axial imaging plane.
This technique provides a wealth of diagnostic information that is accurate, detailed and specific. Usually a diagnostic template is required to take full advantage of this technique.
The innovative implant tip is sharp so the implant works as an osteotome, pushing bone to the side and thereby widening the ridge.
The sharp tip also secures a smooth insertion without the implant wobbling. This ensures the implant will not spin and lose stability when a higher density area is reached.
- using minimal osteotomy, even with as little bone as 3 mm at the bottom of freshly extracted sockets
– using gradual condensing of bone in all dimensions throughout the entire length of the implant, even with as little as 3 mm of bone at the neck of the implant
Adjustment to small changes for parallelism – using the self-drilling capacity it is possible to change direction of the implant during implant placement giving full flexibility for optimal placement
