This report presents a follow up of a clinical case published five years ago by the same authors. In the previous report, the authors showed a young girl treated with a myofunctional appliance due to a mandibular condylar agenesia. After a traditional graft had failed, the patient successfully responded to the functional treatment by forming a mandibular condyle. In this new report, the authors are showing how the mandibular condyle has continued developing within normal limits and, the mandibular ramus has continued positively remodeling. The bone biology embedded in the biological process reported here is discussed by the authors.
