Digital Diagnostic

Fotodocumentation

GAMMA Document Browser:

The GAMMA Document Browser is a comprehensive database and documentation tool. In addition to the classical Gamma modules for diagnostics, it aggregates complete photo documentations as well as any existing documents, such as text files, graphics and spreadsheets. The option for easy and direct presentation of data makes this program an excellent communications tool which is suitable equally for students, in the dental office, or in the dental lab.

The layout of the workspace in GAMMA Document Browser is completely customizable in respect to the user’s requirements. For example, it is possible to conveniently and comprehensibly display all kinds of heterogenous data such as patient photos, CADIAS® x-rays, CADIAX® condylography recordings and all evaluations thereof, such as tracings and articulator settings, side-by-side

Case presentation:

GAMMA Document Browser ensures that entered patient data is consistently kept in a presentable and print-ready format. Indeed, the software also promotes the camera-ready case presentation in front of patients and conference audiences and can further be used for illustration purposes in scientific publications or internet presences.

Data export:

For easily transferring the patient documentation stored in GAMMA Document Browser into other applications, the software provides multiple export functionalities. For example, it is possible to save presentations directly in the format of Microsoft PowerPoint or to copy images of particular cells for easy insertion into the clipboard. In addition, patient images that were once imported into the database can easily be extracted to image files. Similar to the image import, this can be carried out by simply dragging the images into and out of the workspace (drag-and-drop).

Data transfer from GDSW classic:

GAMMA Document Browser stores its data in a standalone patient database, which can be used independently from GDSW classic or even in a parallel fashion. To transfer data into the new format, GAMMA Document Browser provides a conversion functionality. This conversion does not only transfer the general patient information, but also all other data saved in the patient file, such as CADIAX® condylography curves or CADIAS® x-ray tracings. This data is automatically prepared for a structured and presentable display in the workspace. During this procedure, the original GDSW classic is preserved without any changes.

Initial diagnostic

Examination sheet- initial diagnostics:

This easily clearly arranged form is designed to cover all of the questions in dental anamnesis. The user can process the form with the mouse or fill out the fields with the keyboard:

  • The patient’s main concern
  • Special medical anamnesis
  • Dental anamnesis

Calculation of the occlusal index is automatically carried out based on the inputs in the dental anamnesis. It reflects the patient’s own subjective feelings, regarding his/her complaints. A comparison of the subjective and objective situation is a key to evaluation.

Comparative muscle analysis is geared to an evaluation of the differences of the two sides. Palpation is carried out symmetrically, simultaneously and evenly while the patient is sitting comfortably. The patient indicates any differences between left and right, and indicates any possible pain in the palpated areas.

After the bilateral comparison, an evaluation of asymmetry can be made. This can offer insights into any possible disharmonious functional processes.

The examination sheet for chronic pain, tooth status and the possibility for including myofunctional problems, round out the program into a complete anamnesis package.

CADIAX Analyzer

The CADIAX® Analyses module processes and stores data from both CADIAX® jaw-tracking systems, CADIAX® compact and CADIAX® 4.
The program includes a variety of display options, as well as conversions for setting the articulator and wax-up technique. In addition to detailed diagnostic analyses of mandibular movement, it allows for expanded articulator calculations, including the setting of individual anterior guidance units.

The software is especially suitable for CADIAX® users who want to take advantage of the full potential of their device. All the details of the condylography data are clearly displayed on the screen of the PC.

The 3-dimensional displays of mandibular movement are clear and easily understandable for the patient. This is extremely helpful when explaining therapeutic measures to the patient.

 

Movement simulation through eccentric articulator programming

Using the face-bows of the CADIAX® compact and the CADIAX® 4 systems, the coordinate system, which is defined by right and left hinge axis points and the anterior reference point, is transferred directly to the articulator.

This leads to an interlocking system with a logical workflow. Through the mechanical connection between registration and the articulator, CADIAX® provides a precise hinge axis relation for maximum reproducibility.

The data acquired with the registration systems can then be used in the calculation programs for individual patient settings in the articulator.

All calculations are based on the manufacturer’s geometry for the various articulators.

Calculations for sagittal protrusion inserts are made with the protrusion track on hand, by evaluation of the X/Z diagram. 

Calculations for transversal inserts are made with the mediotrusive movements on hand, by evaluation of the X/Y diagram.

The mathematical adaptation of the given articulator characteristics is carried out following a “best-fit” process. The articulator insert (blue) is rotated until it coincides, as closely as possible, to the patient’s registration (red). If the articulator includes various inserts, the program will determine for the best fitting one.

ADIAX® always calculates values for 3, 5 and 10 mm, always processing the total track progression from 0 (reference position) to the given value.

Pre-calculated occlusal guidance for diagnostics and wax-up – CADIWAX® 

The simulation in the articulator is determined by three adjustable guidance units: the two condylar joints and the adjustable incisal table. Posterior guidance is already given with the CADIAX registration.

Occlusion concepts and their implementation in wax-up are defined by means of the incisal table. By adjusting the guidance surfaces in the table, more or less rotation is brought into the movement, i.e., the inclinations of the guidance surfaces on the tooth are determined.

Gamma Dental Software® includes suggested pre-set concepts, as well as the possibility of implementing an individual, computer-generated occlusion concept.

 

TMJ diagnostics:

CADIAX® records the spatial movement of the hinge axis of both mandibular joints simultaneously, bilaterally and in elapsed time. Converted to the intercondylar distance, the system offers the possibility of using differential diagnostics for the static- and dynamic evaluation of the movement tracks.

The advantages of condylographic diagnostics are apparent:

  • The method is non-invasive and carried out quickly
  • The patients are not exposed to radiation
  • The results are dynamically reproducible, independent of the therapist
  • The examination can be carried out in the dental practice; the results are immediately available
  • The ideal enhancement for interdisciplinary communication

Application of an individually adjustable mandible bow for setting the exact hinge axis is absolutely necessary in diagnostic condylography. When using the bow with CADIAX® compact, the hinge axis is manually adjusted before registration.

CADIAS®

CADIAS® is the central diagnosis- and planning module of Gamma Dental Software®.

The program links teleradiographic information from the x-ray program with the articulator, condylography, and other diagnostic findings.

The most important aspects of the evaluation are:

  • Skeletal evaluation
  • Vertical evaluation
  • Occlusal plane evaluation
  • Dental analysis
  • Aesthetic evaluation
  • Dynamic analyses (through link with CADIAX data)
  • Compensation mechanisms
  • Planning (VTO)

Input of points and contours on the x-ray image is carried out directly on the computer screen. First, the x-ray must be saved in the computer as a digital image file.

Unlike “classical” cephalometric evaluation programs CADIAS links x-rays with other input data: anterior guidance, dynamic condylography (CADIAX), CPM, tooth arch). Thus, CADIAS® an interdisciplinary tool for diagnostics and planning.

Cephalometric analyses are often wrongly considered to be relevant only for orthodontic diagnostics and treatment planning. However, these analyses are being accorded more and more significance in diagnostics and treatment strategies involved in comprehensive interdisciplinary dentistry. Considering the statistical distribution of skeletal classes in the overall population, it is evident that skeletal Class I is not the “norm”, but rather, at only 37%, represents a clear minority.

The majority of skeletal relations follow a Class II principle. Because of the considerable compensatory mechanisms involved during dento-facial development, most of these cases still achieve normal dentition, or a close facsimile. Nevertheless, after completion of development, this results in a large number of malocclusions and dysgnathias.

Therefore, when planning treatment for complex reconstructions, it is extremely important to analyze the relation in each individual case, before taking therapeutic action. This applies first of all to treatment of non-dysfunctional patients, but even more so for patients with dysfunction. All of these patients benefit from a systematic diagnostic procedure with standardized data-acquisition and evaluation, appropriate to the complexities of the stomatognathic system.

CADIAS® offers:

  • Statistical analyses, based on individual standards, taking into consideration the functional compensation mechanisms
  • Dynamic analyses by including the articulator’s reference plane and therewith a link to clinical and functional analysis (CADIAX®)
  • Interactive case planning, with immediate feedback from all of the statistical and dynamic analyses

 

Tooth status

Processes input of tooth status, plaque status, periodontal status, tooth mobility, tooth resilience and occlusal functions.

All versions of the software include the module Tooth status.

Case presentation

GAMMA Document Browser ensures that entered patient data is consistently kept in a presentable and print-ready format.

Indeed, the software also promotes the camera-ready case presentation in front of patients and conference audiences and can further be used for illustration purposes in scientific publications or internet presences. For this purpose, the application offers a fully integrated presentation feature, which also supports advanced functionality such as showing/hiding individual cells, defining automatic presentation timings as well as transitions between slides.
