Parallelometer
The parallelometer is a measuring device in dental technology with which the parallelism of tooth walls, tooth cavities, telescopic crowns , bars or the parallelism of the alveolar ridge to the tooth axes is determined and checked. It is used in the manufacture of dental workpieces .
application
The parallelometer is used for the following dental work steps:
- Parallel modeling of crowns and bars
- Parallel milling of telescopic crowns and bars
- Parallel polishing of the workpieces
- Parallel drilling, e.g. B. a pin ledge (pin anchoring of an inlay )
- Parallel alignment of attachments, tooth brackets and connecting bars
- Check for undercuts in removable dentures
The workpiece is clamped in the parallelometer and measured at all relevant points with a measuring gauge. Minor disparallelities can be corrected by the dental technician during the production of the dental workpiece. If this is not possible because the disparallelities are too great, the dentist may have to re-prepare (grind) teeth at the non-parallel places or compensating attachments have to be attached to ensure a common insertion direction. Undercuts can be partially blocked out.
