A combination distraction device and methods of using are disclosed. The combination distraction device comprises a two component portion (an apical and a coronal component) and an expansion component for separating the two components once the device has been initially integrated into the bone. Internal threads of the apical and the coronal components are adapted to operatively cooperating with the threads of the expansion component such that the distance between the apical component and the coronal component is selectively varied. When assembled, the expansion component is advanced into the two separable components by rotating, for example, the expansion component in a clockwise direction. As the expansion component is advanced into the two component portion of the combination distraction dental implant, one end of the expansion component engages the end of the internal thread in the apical component, causing separation between the apical and coronal components thereby forming a gap. Since, when placed in a patient, the apical and coronal components become integrated, fused intra-osseously to the bone, separating these two components expands a distraction gap previously made in the bone proximal the separation point between the two components and provides for the formation of new bone and soft tissue.
