Dr. Petrovic's lab was known to introduce orthodontics to the following ideas [2]

• In 1967, he demonstrated that amount and growth rate of the cartilage in condyle can be changed due to the Orthopedic forces
• Growth categorization of the human tissue level growth can be used as a predictor of jaw growth and treatment outcome when coupled with cephalometric analysis.
