Eligibility
Inclusion criteria
Inclusion criteria: The study included patients older than 18 years, without pathologies of the maxillary sinus, with maxillary sinuses classified as wide (Chan et al. 2014), and with a posterior bone height below 3 mm in the 2nd premolar and 1st molar region.
Exclusion criteria
Exclusion criteria: The exclusion criteria applied were patients with a chronic disease that would contraindicate the surgical procedure, such as uncontrolled diabetes, hypertension and head/neck radiation, smokers (more than 5 cigarettes per day), and patients with habits that could interfere with the treatment, such as alcoholism and drug use, use of prolonged bisphosphonate therapy, and/or a history of previous surgical procedure for maxillary sinus graft.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Histologically assess whether there is an increase in bone neoformation in surgeries to elevate the maxillary sinus, after 8 months of bone graft, when associated with xenogenic biomaterial (Bio-Oss) or L-PRF (group 2) or autogenous bone (group 3). The amount of newly formed bone will be measured in the trephine, in square millimeters. | — |
