Sinus Lift With Newly Forming Bone and Inorganic Bovine Bone
Sinus Lift With Newly Forming Bone and Inorganic Bovine Bone
The aim of this study is to evaluate the efficacy of newly forming bone graft (NFB) in the
 gain of bone volume in sinus lift procedures. For that, it will be compared the tomographic
 bone gain 6 months after surgery between a group that received inorganic bovine bone alone
 (n=8) and a group that received inorganic bovine bone associated with NFB (n=8).
The aim of this study is to evaluate the efficacy of newly forming bone graft (NFB) in the
 gain of bone volume in sinus lift procedures. It will be recruited for this study individuals
 25-60 years of age, both genders, presenting a missing tooth at an upper premolar or molar
 region with 2-9 mm of remaining bone between alveolar ridge crest and sinus floor and the
 existence of an edentulous ridge or at least one tooth condemned to extraction. Sinus will be
 treated by NFB mixed to inorganic bovine bone - IBB (test; n= 8) or IBB (control; n= 8). The
 volume of bone tissue will be evaluated by computerized tomography obtained at baseline
 examination and 6 months after surgery. After this period, biopsies of hard tissue will be
 obtained during implant placement for histologic and histomorphometric analysis.
Inclusion Criteria:

 • Presenting a distance between alveolar crest and maxillary sinus of 2 to 9 millimeters.

 Exclusion Criteria:

 -  History of periodontal surgery at the area on the last 12 months

 -  Use of drugs that affect periodontal tissues (eg: anticonvulsants, calcium channel
 blockers, cyclosporine, bisphosphonates, hormone-based, contraceptives, steroids)

 -  Pregnant

 -  Smokers

 -  Diabetics

 -  History of head and neck radiotherapy
