Comparison of dental crown height in bite impressions

A wax bite impression can serve as a reliable identification of missing and unknown children, particularly in the absence of caries and restorations. Dental crown heights in bite impressions made from noncontoured and contoured wax wafers were compared in ten patients, ranging in age from three to eight years. The contoured wax wafer produced significantly greater crown heights in the casts which were fabricated from it. The differences were most pronounced in the anterior teeth; but generally true for all the teeth.
