What do you call the device used to assess the fitting of dental appliances around the height of contour?

• A. Surveyor
• B. Articulator
• C. Intraoral scanner
• D. Vernier caliper

Answer: (A)

The device specifically used to assess the fitting of dental appliances around the height of contour is known as a surveyor. This instrument is crucial in prosthodontics as it allows the clinician to analyze alignments and measure various parameters of dental casts, particularly for dentures and crowns. By determining areas of undercuts and examining paths of insertion, the surveyor aids in ensuring that the dental appliance will fit properly in relation to the contours of the teeth or alveolar ridge. The articulator, while important for simulating the occlusion and relationship between the maxilla and mandible, does not specifically assess the fitting of dental appliances in relation to the height of contour. The intraoral scanner is a technology that captures digital impressions of the oral cavity, but again, it does not directly measure the specific contour heights. Lastly, a vernier caliper is a precision measuring instrument useful for various applications but does not provide the specialized functionality required to evaluate dental appliance fitting in the context of contour heights. Thus, the surveyor stands out as the essential tool for this specific assessment in dentistry.
