چکیده مقاله:
Introduction: One of the most challenging cases in implantology is severely atrophic alveolar ridges which do not have adequate bone for implant placement. One common treatment option for dealing with this challenge is LeFort I osteotomy with inlay bone graft which allows implant insertion and correction of the maxillomandibular relationship simultaneously. Although this method has a high success rate, it is somewhat invasive and has potential complications in some cases. In recent decades, implant surgeons have focused on less invasive and more predictable treatment options for bone augmentation and implant rehabilitation. Now a question comes into mind when there are not much discrepancies in maxillomandibular skeletal relationship and inter arch distance, do we really need LeFort I down-grafting and take its risks? Methods: In this study, we present a case who did not need any change in the skeletal relationship of the jaws and inter arch space based on examination and prosthetic consultation, so we implemented bilateral simultaneous sinus and nasal floor augmentation instead of LeFort ۱ interpositional inlay bone graft. Results: Six months after the surgery, new radiography showed adequate height and width of augmented bones gained in and under sinuses and nose floor. So there is no limitation on choosing suitable implant lengths and diameters. Conclusion: This study indicated successful augmentation of severely resorbed maxillary alveolar ridge with bilateral sinus and nose floor grafting technique instead of LeFort I interpositional bone graft in a case who didn’t have more discrepancies in skeletal and inter arch space.
