BEHIND THE SCENES Advantages: Pressure machines boast better thermoforming power. They are versatile and can produce virtually any appliance. They are particularly favoured in commercial dental labs equipped with top-notch model production facilities and skilled operators. Additionally, orthodontic surgeries prefer these machines for their inbuilt compressors which provides a good solution when no plumbed air supply is available. Considerations: More attention is necessary for model quality, blockingout procedures, and ensuring a clean compressed air supply. The model remains inaccessible during the process. These machines are ideally used by experienced operators and are pivotal for orthodontic bracket transfer appliances and techniques involving self-cure acrylics. For efficient high-volume production such as aligner sets, it is best to choose a machine with an external air supply. Rapid vacuum machines Operation: Rapid vacuum machines, which do not require an external air supply, operate by accumulating a vacuum in an internal reservoir using an inbuilt pump. After the heating cycle, the foil is rapidly drawn over the model using the stored vacuum, creating detailed and clinically equivalent results to pressure forming. Advantages: These machines do not need a compressed air source, are quieter, more user-friendly, and allow model access during forming. This accessibility facilitates the use of optional occludator attachments, enabling the incorporation of a bite registration into an appliance during thermoforming. Considerations: The less aggressive nature of these machines can lead to more comfortable, passive appliances for patients. Model quality requirements are also less stringent compared to pressure units. These machines are ideally suited for general productions, such as bleach trays, mouthguards, and orthodontic retainers. Its automatic operation and user-friendliness make it suitable for diverse dental office staff. CONCLUSION Choosing the right thermoforming machine boils down to understanding your current and potential future needs. By clearly outlining what one ABOUT THE AUTHOR wishes to produce and keeping in mind the differences and benefits of each machine type, one can invest wisely and set yourself on a path for long-term success in dental thermoforming. Instead of being swayed by budget constraints or features, one should start by asking, “What do I want to use the machine for now and into the anticipated future?” This query provides a clearer path towards Peter Herring is an Australian qualified dental technician, Fig. 2: The material is “pulled” onto the model using the pressure differential created from the vacuum below the model. This leaves the formed material accessible for manipulation while still in a plastic state while the rapid nature of the vacuum release gives results clinically equivalent to pressure, and in some cases preferential selecting the ideal machine that caters to both current and future needs.
