CASE REPORT Socket Preservation and Sinus Augmentation Using a Medical Grade Calcium Sulfate Hemihydrate and Mineralized Irradiated Cancellous Bone Allograft Composite Robert Bagoff, DDS1 Sachin Mamidwar, MS, MBBS2 Ioana Chesnoiu-Matei, DDS, MS1 John L. Ricci, PhD1 Harold Alexander, PhD2 Nick M. Tovar, PhD1* Regeneration and preservation of bone after the extraction of a tooth are necessary for the placement of a dental implant. The goal is to regenerate alveolar bone with minimal postoperative pain. Medical grade calcium sulfate hemihydrate (MGCSH) can be used alone or in combination with other bone grafts; it improves graft handling characteristics and particle containment of particle-based bone grafts. In this case series, a 1:1 ratio mix of MGCSH and mineralized irradiated cancellous bone allograft (MICBA) was mixed with saline and grafted into an extraction socket in an effort to maintain alveolar height and width for future implant placement. MGCSH can be used in combination with other bone grafts and can improve handling characteristics and graft particle containment of particle-based bone grafts. In the cases described, we found that an MGCSH:MICBA graft can potentially be an effective bone graft composite. It has the ability to act as a space maintainer and as an osteoconductive trellis for bone cells, thereby promoting bone regeneration in the extraction socket. MGCSH, a cost-effective option, successfully improved MICBA handling characteristics, prevented soft tissue ingrowth, and assisted in the regeneration of bone.

Increasing this volume in the edentulous posterior maxilla or immediately after the extraction of a tooth is orchestrated by the careful preservation and stimulation of the wound healing and bone 1 NYU College of Dentistry, New York, NY.

This process can be affected by infection,1 difficulty during tooth extraction,2–4 patient age,3,5 and heavy tobacco use.6 The goal is to obtain a ridge with adequate bone volume and minimal postoperative pain at the time of implant placement. To enhance the bone healing process, surgical treatments and bone regeneration techniques, such as guided bone regeneration (GBR) and sinus augmentation, have been studied. GBR and sinus augmentation focus on regenerating and increasing the amount of hard and soft tissue in a defective Journal of Oral Implantology 363
