[Cooperation between dental practice and the commercial dental technology laboratory].

Questionnaires were distributed to 150 practicing dentists and 150 commercial dental laboratories in Baden-Württemberg in order to work out the state of cooperation and the possibility for improving the partner relationship. Two important points were established: 1. When communication between both partners is improved, the quality of the tooth replacement to be constructed is also improved. 2. Inaccurate impressions and instructions by the dentist confuse the dental technician and lead to independent and often inappropriate decisions and actions.
