Brief Summary:
the purpose of the study is to look for differences in dimensional variations of augmented maxillary sinuses with or without the placement of a collagen membrane subjacent the sinus mucosa.
Detailed Description:
Material and Methods: After the elevation of the maxillary sinus mucosa, a collagen membrane with standard dimensions will be placed at the test sites subjacent the sinus mucosa and the elevated space will be filled with a xenograft, both test and control groups. A collagen membrane will be placed to cover the antrostomy at both groups and sutures will be provided to close the wound. After six months of healing, mini-implants will be installed. After 9 months, biopsies containing the mini-implants will be harvested for histomorphometric analyses. CBCTs will be taken for all patients before surgery (T0), after 1 week from sinus floor augmentation (T1) and after 9 months of healing (T2). Osseointegration of the mini-implants and dimensional changes over time of soft and hard tissues will be evaluated on the CBCTs.
