CAD CAM SOFTWARE DENTAL FULL
A 5-axis machine being controlled by 3+1-axis CAM software is not going to get the same results as the same machine run with a 3+2- or full 5-axis CAM. There have been machines purchased with capabilities that the CAM software does not support. This is a great example of how CAM software and machines need to work together. Now the CAM technology will carve away the end of the block in one piece to make the process considerably faster. Up until recently, when machining a glass ceramic material, the entire block had to be ground away. Grinding uses an abrasive machining process, meaning diamond burs, whereas milling is cutting the material, using a fluted bur. This is different from milling in that the tools that are used change. For example, when machining glass ceramic materials, the software is required to have grinding capabilities. Meanwhile, other advancements are being made that were unheard of previously. Obviously, this isn’t a problem in today’s reality of machining, where most machines have some sort of 5-axis capabilities, be it full 5-axis or 3+2. This little advancement in the CAM software enabled laboratories to mill taller bridges in thinner discs. Later the CAM software allowed for milling at different a-axis angles, always 180° off each other. This would allow for milling the top and bottom of a restoration.

Early CAM software would mill with the disc in 0° and 180° positions. This means the spindle would move in three directions (x, y, and z), with an added fourth axis (a) in the puck holder. Most early laboratory machines were 3+1-axis milling. The CAM software is what tells the machine how and where to move.Įarly versions of CAM software would be laughed at today. The machine is exactly that-a machine it does only what it’s told. While often overlooked, the CAM software has more of an impact on the milled result than the machine itself. How fast should the spindle speed be set? How fast should the tool be moving across the material? How deep should the tool plunge into the material? All of these questions have bearing on parameters within the CAM software. Shortly after that, however, other milling parameters started to be examined. Initially, the motives were to add smaller tools, thereby enabling a finer detail of the designed anatomy.

This is where the CAM software comes into play. It has not been until more recently that milling parameters have started to be examined. The early adopters have been tweaking design parameters for years. This could be an upgraded PC, adding a second mill, or the need to adjust parameters for better fit of the restoration, to reduce milling times, or to get a different finish out of the machine.Īs CAD/CAM has become mainstream in the dental workflow, more and more people have looked deeper into how each of the six individual parts work and can be optimized. Users of CAD/CAM started to want to change parameters in their system, or upgrade/replace different parts.

Open systems are more desirable because of the interest in customization for each laboratory’s use. closed systems, and now most would agree open systems are preferable. Just a few short years ago, the debate in digital dentistry was open vs. In the beginning, for the most part, people wanting to go digital felt they were buying a couple items (scanner, PC, and mill) because all the parts came packaged together. Some of these parts get lost or forgotten when we as dental laboratories or clinicians look into purchasing a system. These are the scanner, software to run the scanner, a case management system, design software, CAM or nesting software, and a milling machine. Optimizing today’s mills with effective softwareĪ typical CAD/CAM system in a dental laboratory consists of six distinct parts. The Difference CAM Software Makes in Dental Machining
