The aim of this paper is to illustrate the use of a Posterior biteblock modified with TPA and Palatal crib to obtain the vertical control of maxillary molars, restrict tongue pressure as well as Intruding posterior molars thereby autorotating mandible. Case report Use of posterior biteblock modified with TPA and Palatal crib for correcting Anterior Openbite in growing individual is illustrated. Patient was successfully treated, and the open bite was fully corrected thanks to molar intrusion, following counter clockwise rotation of the mandible and tongue correction. Finishing of alignment was performed in phase II of the treatment with conventional appliances. Conclusion Posterior biteblock modified with TPA and Palatal crib proved to be effective in controlling the vertical position of maxillary molars promoting the counter-clockwise rotation of the mandible and stimulating a different tongue posture.
