Background. The design of removable partial denture (RPD) has an important role in the health of dental and periodontal tissues. Dentists are responsible for the design since designing it requires mechanical and biological considerations. There is lack of literature focusing on the behavior of dentists in Turkey concerning the design of RPDs.
Objectives. This study aimed to assess the capability of dentists to transfer RPD design information to dental laboratories, and to determine the factors playing a role in the designing or transferring the design information.
Material and Methods. A questionnaire was distributed to 25 dental laboratories in all geographical regions of Turkey. Design instructions of RPD provided by dentists using a prescription form, phone call and internet were examined. Clinic type, communication method, way of showing design information, and specialization in prosthodontics were recorded to investigate their association with design information. The data was analyzed with descriptive statistics and χ2 test.
Results. Approximately 2/3 of the dentists did not mention any design information in the instructions. Laboratory prescription form was the most frequently used communication method. Design features were mostly indicated in diagrams. The ratio of indicating design information was higher among prosthodontists. Over a half of the dentists who mentioned design information in their instructions were from private dental clinics. The dentists who preferred both writing and drawing for showing design specifications had the highest ratio of showing rest type, clasp location and rest location in their instructions.
Conclusion. The majority of dentists do not mention any design information. Expertise in prosthodontics and type of dental institution affect the content of the design information. Showing design features in more than 1 way seems to increase the amount of design items. Training dentists in aspects of RPD design and evaluating the circumstances of clinics is essential.
