Case Study Design of a training place for a dental technician


The company is a dental laboratory.

Man's disability and impairment:

The man is missing his right hand and part of the forearm from birth. As a result, he is limited in holding, carrying and grasping. The GdB (degree of disability) is 50.

Transition from school to vocational training:

After graduating from high school, the man completed an internship of six weeks in the dental laboratory. During this time, the man convinced the owner of the dental laboratory of his abilities, so that he received a training position as a dental technician after the internship.

Vocational training and workplace:
The man uses a forearm prosthesis with an electric hand (myoelectric forearm prosthesis) for the practical work to be performed in the dental laboratory during vocational training. An electronic control built into the forearm prosthesis enables the speed and grip force of the electric hand to be regulated by the strength of muscle signals from the arm. This enables powerful gripping, but also gentle grasping of small and fragile objects. With the electric hand, the man can thus hold objects and bring them into position, while he performs the necessary fine motor activities with his left hand.
In addition, the following assistive products were used or provided for ergonomic work design:
- an electrically height-adjustable workbench with gas, air and electrical connections,
- a dust extraction system with a swiveling extraction funnel,
- two arm rests and
- a swiveling workplace light.
While work at the electrically height-adjustable workbench and at the laser welding system is performed in a seated posture, plaster work at the plaster table is performed in a standing posture. This means that the body posture can be changed more frequently during the working day. All settings on the laser system are made via a multi-function foot control, so that the hands remain free for fully concentrated and uninterrupted work.
