Precision dentistry redefined.

0.21-0.46
In today’s dentistry during orthodontic and prosthodontic treatment, special emphasis is paid to the position of lower jaw in space.

0.46-1.17
Known/existing solutions.

1.34-1.40
Algorithm used in known solutions.

2.07-2.12
How does auto segmentation work? How precise are 3D-models of TMJ?

2.56-3.02
Lets take a closer look at commonly used auto-segmentation method and analyze problems
with this technological solution.

7.05-7.21
To evaluate movements of complex 3D object, it is not enough to represent this object in the form of one point.

10.26-10.34
3D-models are allocated in specially designed window interface for convenient visualization.

14.10-14.26
Available alternatives.
CFx is obvious advantage in precise visualization and analysis of TMJ compare to available alternatives.

14.26-14.47
CFx can be used in clinical practice, as independent diagnostic software module, but its maximum
efficiency can be achieved by integrating CFx with systems, recording/displaying movements of mandible. CFx can be integrated into any protocols of treatment: gnatological, neuro-muscular or a combination of both.

14.47-15.10
Utilizing CFx method in clinical practice allows:
- to create highly precise 3D-models of condyles and articular fossas of TMJ with thickness of contours in diameter of 100 microns.
- precisely set mandible into treatment position and fabricate various restorations.
- avoid distortion when obtaining 3D-models of TMJ using common methods of  CT auto-segmentation.

With rapid expansion of 3D technology in dentistry the question of implementing this amazing technology still remains a grey area when it pertains to the TMJ. We use more and more of this technology on a daily basis and for some practitioners, it has replaced traditional approaches in many aspects of their practice and even became a protocol of treatments.

Today's rapid development of digital dental planning and prototyping systems, allows practitioners to concentrate on precision of treatment outcomes and emphasis on diagnostics and control of all structures involved in a treatment along with TMJ is undoubtedly essential. Common methods of computer mapping, displayed on a monitor, mathematically and on programming level - evaluate movement of condylar contours in relation to articular fossa of TMJ. Scientific and clinical value of common methods is significantly decreased with distorted models of not precisely detailed contours. This is due to known methods of auto segmentation, used to construct
an isolated 3D objects are based on the brightness of a CT image points, wherein they are unable to precisely identify an object with borderline value.              

Precision in contouring leads to a significant distortion of 1 mm or more as a result. The presence of cartilage outside, as well as inside of a joint is interpreted as bone, or its absence, which misrepresents the volume concept and creates inaccuracies constructing the 3D layout of TMJ. Current software solutions do not provide a convenient, detailed display of TMJ structures, which are represented as 3D objects obtained by CT auto segmentation , therefore do not allow practitioners to precisely analyze changes and movements of objects.    

The reason for the above is that 3D models of condyles and articular fossas are obtained using the auto-segmentation method.  In known methods of displaying tracking of mandible movements on computers, in fact we see the movement of significantly distorted 3D models of TMJ, which greatly reduces the scientific and clinical value of known methods. All softwares bear the same problem of precision of 3D models of condyle and articular fossa. This is one of the reasons why the evaluation of trajectory of movement is used by the means of one point tied to condyle. To evaluate movements of complex 3D object, it is not enough to represent this object in the form of one point.

During this extensive research, Biostek DT came up with a new method of Constructing and Visualizing 3D images
of TMJ with precision of 100 microns !!!

“CF-X” is a patented invention that allows diagnostic precision of position and movements of condyles in TMJ from
a margin of error of 1 mm or more to 100 microns. Consequently, it leads to a significant increase of clinical value in performed procedures.                            
Increase in diagnostic precision, control of condylar position and movement in TMJ, constructing 3D models
of TMJ with precision of under 100 microns, defining more accurate mandibular treatment position to further manufacture all kinds of restorations  fixed and removable prosthesis’s, inlays, onlays, splints and functional orthodontic and orthotic devices is the technical result of this invention.
Utilizing CF-X method in clinical practice allows:
- to create highly precise 3D models of condyles and articular fossas of TMJ with thickness of contours in diameter of 100 microns
- precisely “set” mandible into treatment position and fabricate various restorations.
- avoid distortion when obtaining 3D models of TMJ using common methods of auto-segmentation.

Biostek DT will continue to update digital dental enthusiasts all across the globe with the development of this invention.

Stay tuned…
