Abstract

Maxillary sinus floor augmentation has been used for occlusal rehabilitation with prosthetic appliances installed over dental implants in the posterior maxilla despite the fact that this region often presents loss of alveolar bone and increased maxillary sinus pneumatization, particularly when all of the molars are absent. The shortage and quality of the remaining bone often implies a challenge when rehabilitating with dental implants. Different kinds of grafts have been used in an endeavour to solve these problems. The aim of this
study is to find out if there is a significant difference in the bone formation between the 6th- and the 9th - month periods after sinus lift grafting with a calcium- phosphate paste (Maxresorb inj. (Botiss Dental, Berlin, Germany)). For this purpose а bilateral sinus lift has been made by own methodology. Results showed no significant difference in the percentage of newly formed bone in the sixth and the ninth month, which warrants the dental implants to be placed on the sixth month post-sinus lifting.
