Dental laboratories have many tasks in common where extreme precision has to be performed. Restorations such as crowns, bridges, implants, full dentures are subject to performance criteria such as correct fit, finish or color scheme. To fulfil these criteria, rework and inspection on the finished dentures are necessary.

Inspection and checks

There are many areas within dental technology that require magnification. These include the inspection of dies, patterns, castings for fit and passivity of spans and porcelain for cracks, chips and surface finish.

The unreinforced eyesight of dental technicians is not usually sufficient to be able to produce the required quality of dental rework. It is therefore extremely important to use a magnifying device that can provide a realistic, 3D image and true color representation of the subject.

Dental Laboratory

Bench magnifiers are not ideal for such applications, as they don’t offer not enough magnification and give too much distortion. The Mantis® range of stereo microscope is an extremely popular magnification tool for dental technicians with its versatile universal stand and ergonomic viewing head.

Predominantly, a Mantis Compact with a 6x objective lens is used for general inspection work and Mantis Elite with up to 10x magnification is used for modifications.

The Mantis Elite also has an interchangeable turret that allows for technicians to quickly change from low to high magnification. With the option of an articulated arm, the Mantis can be quickly and easily fitted to the workbench in the lab.

Finished crowns can also be checked under the Mantis where color rendition is at an optimum because of the new true light LED illumination.

Modifications and dental rework

Dental Rework

It is important in dental technology to make sure that any modifications are carried out accurately in order to prevent the loss of fit. For rework of products in the dental laboratory a few requirements must be fulfilled by the magnifying device:

  • Good hand-eye coordination
  • Enough space between lens and object
  • Easy positioning of the magnifier over the object
  • Lens protection and dust proof
  • Ergonomic, fatigue free operation
  • Magnification for the normal operation 4x or 6x

All these requirements are met by Vision Engineering’s Mantis Compact with universal stand.

The Mantis provides ergonomic advantages, preventing eye fatigue and muscle strain, thus allowing the user to work comfortably for longer periods.

Working under magnification

The Mantis delivers a solution when tasks such as trimming dies, fabricating accurate patterns and adjusting the fit of castings need to be carried out under magnification. The long working distance and freedom of head movement allows the operator to work comfortably and accurately.

The large depth of field allows the work to be viewed at a greater magnification through the stereo viewer with an increased amount of the subject in focus thus providing for a greater overall perspective when working on one specific area.

These are the reasons that have very many dental labs worldwide decided (in Germany about 60%) to use of the patented device Mantis® from Vision Engineering.
