Highly accurate frameworks for partial dentures are designed in a few minutes, ensuring significant savings in both time and materials.
More details. Availability date:. Dental technicians who use exocad can easily complete even complex implant bar designs, which greatly enhances work efficiency. This leaves us with more freedom of choice. When we first started working with exocad, we already had longterm experience with other popular dental CAD programs. Despite diving into the exocad experience with no training, we found we were able to design crowns and bridges that very same day.
Five years and several thousand designs later, we have come to the conclusion that exocad can handle almost any case we throw at it! Thanks to its intuitive user interface, you can work on any design without the need for extensive training, and its flexibility facilitates the design of even the most exceptional cases with ease.
Every new feature exocad has provided over the years offers new possibilities and tools for handling every conceivable scenario, quickly and with no fuss. You can choose between Perpetual License with optional upgrade contract or the subscription-based Flex License with significantly lower initial cost, and full access to all upgrades.

With DentalCAD , the choice is yours: Easily and seamlessly integrate our powerful dental CAD software solution with all exocad products and modules in one seamless digital workflow.
Exceptional usability, performance and flexibility are guaranteed. Enough wax is removed to expose the junction of the yellow with light orange, which corresponds to the 0. This is performed on the midfacial portion of the second premolars. Make sure the appropriate undercut is exposed. The parallel block out is shown completely eliminating all undercuts.
The maximum thickness can be adjusted to avoid over or under application of wax. In conventional methods, gauge wax is used. For this software 0. Three 9. Internal finish lines are positioned during step one or when the outlines of the retention grids are established. While this sequence helps avoid mistakes that require erasing pencil marks on a stone cast, on a virtual cast this concern is eliminated.
While the sequence differs from conventional techniques, the RPD design should be consistent with the principles of RPD design. Begin with a series of points to outline the desired area. When the loop is completed the area will fill in with a digital representation of a layer of relief wax. The borders of the wax relief define the internal finish lines. Make sure that this line extends mm from the tooth tissue junction so that this area will later be covered with the minor connector.
The same tool is illustrated below where the distance from major connector to the tooth tissue junction is evaluated. This will allow proper connection to the open lattices denture base connectors. The space between the points is averaged to produce a continuously smooth edge of the connector.
Advanced users are able to customize the cross sectional configuration by manipulating the program settings. Wax relief for the open lattices are placed mm from the tooth-tissue junctions. The height of the bar should be approximately 4 mm. The thickness of the inferior portion of the bar should be approximately 2 mm. The software reads a measurement between any two points along a straight line. Since we desire a minimum 3mm of clearance from the major connector to the free gingival margins this tool is utilized to accomplish this task.
Notice that wax is seen in yellow; parallel block out is seen labially and relief wax is seen between the major connector and the soft tissue.
Major Connector Minor connector splines are also utilized to form a latticework over the previously laid relief wax for denture base connectors. The software allows the clinician to design these components in any sequence. The authors recommend designing rests first. Minor Connectors, Retainers and Rests Clasps The window associated with the cingulum rest is created in the following manner.
A cingulum rest is created with the occlusal rest tool. The window is created by combining the rest with a minor connector as a short lingual plate. Rests Clasps Begin with a spline forming the outline of the grid pattern making sure to overlap with the proximal plate and the major connector. In the example shown two cross struts complete the open lattice.
Denture Base Connectors Clasps Each point on the spline can be modified in thickness and height, hence defining the 3-dimensional taper. Half-round dimensions at the shoulder of circumferential clasps should have a base of 1.
The dimensions at the tip should be half that of the shoulder. Rests also provide a number of other functions including indirect retention, positioning the denture correctly and distribution of load. Retention is preventing displacement of the denture AWAY from the mucosa. This is usually achieved by clasps but also sometimes by altering the path of insertion.
Clasps can either be:. Clasps provide direct retention and prevent this displacement. Only the final third of the clasp engages the undercut. When something like a clasp is placed around a tooth, during disengagement from the undercut, the clasp will apply a lateral force on the tooth.
Over time, this will cause the tooth to tip and weaken. Therefore, something is needed on the opposite side of the tooth the reciprocate this force i. So reciprocation is balancing the sideways force on a tooth. The reciprocating plate must be in contact with the tooth in order to function properly. Bracing is preventing sideways and anteroposterior movement of the denture.
Often this occurs automatically through the extension of the denture itself. In these situations, extending the footprint of the denture can prove to be beneficial. Connectors are the components of the denture that join everything up, which can be minor or major. Minor connectors join the smaller components to the saddles, while major connectors join the saddles up and complete attachment between the two halves on the arch. Connectors also help in terms of support, bracing and indirect retention.
