The purpose of this study was to determine the methods dental practitioners in the United Arab Emirates (UAE) use to communicate cast removable dental prosthesis (RDP) design to dental laboratories; identify common practices taken by dentists/dental technicians prior to fabrication of RDP framework; and seek out dental technicians' attitudes toward their role in RDP design decisions.


All dental laboratories (n = 28) listed in a local telephone directory were invited to complete a questionnaire through a face-to-face interview. They were also requested to examine RDP cases fabricated in the past 2 months and identify steps taken by dentists/dental technicians prior to fabrication of the framework. Descriptive statistics were used to report frequencies and percentages.


Twenty-one (75%) dental laboratories agreed to participate, out of which 19 had the facilities to fabricate chrome-cobalt RDPs. Cast RDPs comprised approximately 4.04% (±2.67) of services provided. A reported 84.2% of dentists frequently communicate through generic lab script, with 89.5% rarely/never giving details regarding RDP design. While 52.6% of labs agree/strongly agree that it is the dentist's responsibility to decide the final RDP design, 94.7% agree/strongly agree that dentists should depend on dental technicians for design-making decisions. A total of 19 RDP cases were reviewed. All 19 were surveyed and designed by dental technicians but received dentist approval of design prior to fabrication. Thirteen (68.4%) had rest-seat preparations done by dentists after approval, and new impressions sent to the lab. No other tooth modifications were noted.


The responsibility of RDP design appeared to be largely delegated to dental technicians. Importance of tooth modifications seemed to be undervalued and not completed prior to framework fabrication.
