[Longitudinal study to demonstrate the effectiveness of prevention-oriented therapy with cast removable partial dentures].

Proof of the preventive effectiveness of removable cast partial dentures is given in a prospective clinical longitudinal study over a 2-year period. 34 patients at middle age, treated with these therapy remedy, had been examined by applying a standardised method. In addition to the dental recall program, care for oral hygiene was ensured at regular intervals. Following the objectified findings related to the tooth surfaces, for the first time it must be emphasized that area-differentiated high-risk areas exist requiring painstaking care on cleaning. All together, it has been ascertained that no essential deteriorations in the oral health conditions were found. The conclusions recommend the tried and tested removable partial dentures in respect of their structural conservation effect.
