Abstract

Some conditions are necessary when placing an dental implant, good bone density, heigh and weight must be available in the alveolar process. Tooth decay, trauma, periodontal desease and other causes can lead to tooth loss and subsequentely bone loss. Therefore, many sites where dental implant are needed have also lack of bone support. The main of this presente study is to report a case where a implant surgery was performed using rotatory instruments Bone Expander®, for volume gain in atrophic alveolar ridge and low bone density, due to the absence of the four upper incisors. Guided Bone Regeneration was associated in order to gain vestibular bone volume in the alveolar ridge. The results showned that the use of Bone Expander® is able to expand the alveolar ridge horizontally and at the same time compacting bone in the inner walls of the prepared site increasing bone density in this area and allowing to the implant greater primary stability.
