Anterior Open Bite Treatment With Bonded Spurs Associated With Build-ups Versus Conventional Bonded Spurs

Twenty-five patients will be treated with bonded spurs associated with posterior build-ups. The cervical portion of the palatal surfaces of the maxillary incisors and the incisal portion of the lingual surfaces of the mandibular incisors will be pumiced, rinsed, dried, and acid etched with 37% phosphoric acid. The etched surfaces will be subsequently rinsed and carefully dried. Then, the spurs will be bonded using Transbond primer/adhesive. The positions for the spurs will be chose to prevent possible future occlusal interferences The spurs will be sharpened with a carborundum disk before bonding. In addition, posterior build-ups (resin blocks) will be cemented on the functional cusps of all maxillary posterior teeth. The treatment time will be 12 months. After this time, the posterior build ups will be removed and the bonded spurs will be maintained for 12 months more, as active retention.

Twenty-five patients will be treated only with bonded spurs. The bonding of the spurs will follow the same protocol described for the experimental group. The treatment time will be 12 months. After this time, the bonded spurs will be maintained for 12 months more, as active retention.
