The premaxilla was separated from rest of the alveolus which can be clearly appreciated in 3D CBCT scan. Thus upper alveolus was separated into three different parts which will severely affect the development of teeth later.
Maxillofacial Surgeon Dr. S. M. Balaji performed the premaxillary setback procedure with rhBMP-2 which helps in uniting the three parts into a single jaw bone with new bone formation. This surgery helped for proper growth and development as well as alignment of his teeth.
