Functional rehabilitation using orthognathic surgery, bone transplants and implants after irradiation of malignancy in early childhood.
Functional rehabilitation has been carried out in four young patients by use of orthognathic surgery, bone grafting and implants. All four patients had been successfully treated for malignant tumours in the midface during early childhood by use of full dose irradiation. Retarded growth of the maxilla together with missing root formation of permanent teeth prevented the alveolar process to develop. Bimaxillary osteotomies with inlay bone graft have been made in two cases and maxillary osteotomy le Fort I with interpositional and inlay grafting in two individuals. Implants surgery has been made in a second stage surgery. A total of eighteen implants has been inserted and during five years follow-up two implants have been lost (survival rate 90%). All patients have been successfully rehabilitated with fixed bridge prosthesis.
