At the back regions of maxilla, often are unable to accommodate dental implants because of thin bone thickness. In these cases, the procedure of lifting the maxillary sinus floor is the viable option to rehabilitate this area. One of the main reasons patients give up treatment is the waiting time between the bone graft and the installation of dental implants (around 6 months). This research sought to use Human Growth Hormone (GH), together with Lyophilized Bovine Bone (Bio-Oss®), in Maxillary Sinus Floor Survey procedures to analyze whether there is a reduction in bone maturation time. In the first phase of the work, three patients were operate bilaterally, and on one side the conventional maxillary sinus survey and on the other side was add Human Growth Hormone (Somatropin). After 3 to 5 months were make Computed tomography of cases operated. The images obtained were assemble in questionnaire format, without identification of the patient, material used, time after surgery and use of GH or not. The questionnaire was forwad to 52 Oral and Maxillofacial Surgeons, by e-mail. At the end of the work, we concluded that growth hormone-enhanced grafts obtained full majority of the evaluators' agreement to install the implants at the time the Topographies were make. Unlike in the group without Growth Hormone, the great majority of the evaluators considered the moment inopportune for implant installation. These results demonstrate positive interference in the quality of the tomographic image, when the increase of the Growth Hormone was make, according to the opinion of the evaluators. Key
