Early Tissue Response to Rapid Maxillary Expansion in the Midpalatal Suture of the Rhesus Monkey

Rhesus monkeys were used to study the bone and connective tissue response of the palatal sutures after relatively short periods of rapid maxillary expansion. The results indicate that resorption is responsible, in part, for midpalatal suture splitting and, after this, heavy deposition attempts to maintain sutural morphology.
