A wide variety of dental procedures involve getting a dental model of the patient's mouth. This is done by taking an alginate or silicone impression and then pouring dental gypsum or plaster inside. When the dental gypsum solidifies, the practitioner can remove it from the impression to obtain an exact replica of the patient's oral cavity.
However, it is highly frequent for these models to have irregular edges or gypsum excesses at the base and sides.
Although gypsum is solid and resistant, these imperfections can be fixed with a dental model trimmer.
A dental model trimmer is a laboratory machine that allows practitioners to trim the edges and base of any dental model. Therefore, it fixes all imperfections around the model, leaving its edges smooth and flat.
The dental model trimmer consists of a large disc placed inside a cylindrical machine. The machine possesses a motor that causes the disc to spin at high speed. The dental model trimmer also has a small platform or base in front of the disc. This base is used by the practitioner to place the dental model and safely press it against the spinning disc.
Furthermore, the base angle can be adjusted in some trimmer models for a more precise trimming process.
These devices can spray water into the disc and the dental model. This makes it easier to trim the model and prevents it and the disc from breaking.
