For patients with alveolar bone loss, VBW are superior to HBW when assessing bone levels, density, morphology, tooth furcations, and evaluating interproximal contact areas for caries. It is recommended that the vertical bitewing technique be taught as a standard in dental, dental hygiene, and dental assisting schools for adult patients showing evidence of posterior interdental bone loss.

A comparative analysis of horizontal versus vertical bitewings was performed to evaluate the effectiveness of each method in capturing the distal of canine and in opening interproximal tooth contacts. (Abstract Archives)

On a properly positioned and correctly exposed horizontal or vertical bitewing radiograph, one would not be able to observe the periapical area around the involved teeth, unless the teeth were anomalously short. (Dental Economics)
