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.

t is necessary to have a suitable amount of
alveolar bone volume for proper functional
aesthetic dental implant placement. Increasing this volume in the edentulous posterior
maxilla or immediately after the extraction of a
tooth is orchestrated by the careful preservation

regeneration process. 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
