Female patient age 43 underwent extractions 20+ years ago, maxillary arch. Presently interested in replacing missing teeth with fixed implant supported prosthetic. Patient also has a very rare disorder characterized by slowly progressive deterioration of the skin and hard and soft tissues on the left side of the face. Questioning if any consequences and or complications may arise after performing maxillary arch augmentation using Khurry technique with bone graft for future implant placement. All opinions and suggestions are needed. Thank you.
