LE FORT I OSTEOTOMY WITH INTERPOSITIONAL GRAFT AND IMMEDIATE LOADING OF DELAYED MODIFIED SLACTIVE SURFACE DENTAL IMPLANTS FOR REHABILITATION OF EXTREMELY ATROPHIED MAXILLA: A CASE REPORT

PURPOSE: To describe a successful clinical case of immediate prosthetic loading of modified sandblasting and acid-etching surface ITI dental implants inserted in a grafted maxilla after Le Fort I osteotomy. MATERIALS AND METHODS: A 59-year-old man with a severely atrophied maxilla was treated with Le Fort I osteotomy and interpositional iliac bone graft. Thirteen weeks later, 7 modified sandblasted and acid-etched surface ITI dental implants were inserted with immediate application of a screw-fixed prosthetic acrylic device kept in functional loading for 3 months until a definitive fixed prosthesis was inserted. RESULTS: After 20-month follow-up there has been no implant failure, with minimal bone loss and healthy peri-implant soft tissues; the patient is functionally and esthetically satisfied. CONCLUSIONS: Immediate loading of implants placed after Le Fort I osteotomy and interpositional iliac bone grafting could be an applicable protocol to rehabilitate extremely atrophied edentulous maxillas
