Horizontal vascular-stalked split osteotomy (HVSO): a bone augmentation technique for the atrophic jaw- a retrospective cohort study in 29 patients.

Background: Implant therapy in the advanced atrophic jaw remains challenging in oral and maxillofacial surgery. Hence, a plethora of different augmentation procedures to increase bone volume in the maxilla and mandible have been published. Horizontal vascular-stalked split osteotomy (HVSO) represents a safe and effective approach for the three-dimensional jaw augmentation since it combines maximum vascularization through lingual or palatinal periosteal stalking with reduced grafting morbidity.
