Dimensional Measurement for Dentistry

Dentistry requires development in hand skills throughout the undergraduate and postgraduate programs both in the pre-clinical and clinical settings (Allred, 1977). The level of expertise achieved depends on the level of training, the natural ability of the dentist and also experience. Tooth preparation for a crown is a common procedure in general dental practice and it is essential that dental students are able to perform this procedure competently before they graduate. The skill training of these techniques is in itself subjective, as there is use of “eyeballing” of the preparation rather than a definite measure. There is clearly a need to obtain more formal dimensional assessment of crown preparations. This will assist in the feedback to and the training of dentists and also in the practise of dentistry.
