How dental labs automate milling with Oqcam

The mainstay of many dental productions is CNC milling, a manufacturing technology used to make crowns, bridges and abutments. The demand for milling is high, but staff needed for these jobs are few and far between. In fact, today’s labour market is going through a great shortage of dental technicians and many are expected to retire.

With staff in short supply, the pressure on existing technicians is mounting. The bigger, more successful dental labs need to operate like well-oiled machines to deliver orders on time. This involves a strict schedule, with staff required to process an exact number of parts or files per day.

But a closer look at the production reveals ample opportunity to turn things around. Many of the manual tasks that technicians perform are repetitive and time-consuming, and information they need is scattered across different locations. In such environments, a digital all-in-one platform, with extensive automation capabilities is a game-changer.

With this in mind, Oqcam developed a unique, intelligent software for dental production. Its infrastructure is built on state-of-the-art AI models that automate most production workflows you’ll find in a dental lab, including various tasks in CNC milling.

This has already resulted in immense time savings. French dental prosthetics company Crown Ceram is one such example. Founded 40 years ago as a family business, by the end of 2019 they grew into a production centre with eight milling machines, five 3D printers for resin and three metal 3D printers. In Oqcam, they found a single solution that enabled them to increase productivity and take on increasingly complex projects.

How AI automates milling

So what does milling with Oqcam actually look like? To understand this, let's examine one of the most common applications for CNC milling – crowns and bridges. With Oqcam, all these steps are automated:

• 1. Importing files: You can import up to 53 file formats and Oqcam will automatically repair any errors in the files.
• 2. Feature detection: Oqcam’s AI automatically identifies the part it’s processing, whether it is a single coping crown or bridge with multiple elements. Oqcam will also map out the features, such as the margin lines and the proximal surfaces.
• 3. Orientation: Nowadays, many dental technicians manually orient their parts, but with Oqcam, parts are automatically oriented, scaled and positioned in stock, minimizing undercuts and respecting tool axis limitations.
• 
• 4. Stock selection & nesting: Sorting through a stock of new and used discs can be tremendously time consuming, especially in larger production centers. In Oqcam, the right disc is automatically selected depending on colour, thickness and how much used material is available. The software will also automatically nest the crowns and the bridges for you.
• 5. Pin generation: Oqcam generates pins automatically in line with industry standards, but it also allows you to choose your preferred settings. The software also learns from users decisions and applies them to future jobs.
• 6. Tool path generation: Oqcam calculates toolpaths and generates the necessary NC files. Based on feature detection, milling templates are automatically assigned, thereby optimizing machining efficiency.

These automation capabilities are already saving dental labs time, and allowing them to increase output. And the best part is they don’t have to compromise the quality of their product or invest hundreds and thousands of euros into new machines.
