Eligibility

Age
18 Years to 60 Years

Inclusion criteria

Inclusion criteria: Be between 18 and 60 years old; have the need for bilateral maxillary sinus floor elevation for subsequent installation of osseointegrated implants; present bone availability associated with the alveolar ridge adjacent to the maxillary sinus of less than or equal to 3mm; be in good systemic health; have at least 4 months of healing in the socket after tooth extraction

Exclusion criteria

Exclusion criteria: Smokers; uncontrolled diabetics; individuals with chronic or aggressive periodontitis; patients using medications that alter bone metabolism; patients with chronic upper respiratory tract infections; patients who chronically use anti-inflammatory drugs and antibiotics; individuals with bruxism; alcoholics; drug addicts; pregnant women or those who wish to become pregnant in the next year; history of radiotherapy treatment in the head and neck region; individuals with pathologies that affect bone metabolism; patients who had a major membrane rupture during the trans-surgical procedure.

Design outcomes

Primary

MeasureTime frame
To evaluate tissue composition (% newly formed bone, % soft tissue, and % residual bone substitute), as well as the volume and microarchitecture of grafted maxillary sinus areas treated with different bone substitutes, with or without the use of PRF. Four experimental groups will be compared (PRF + Bio-Oss®, Bio-Oss® alone, PRF + Nanosynt®, and Nanosynt® alone), with an expected minimum detectable difference of 10% between groups. Outcomes will be assessed through histomorphometric and three-dimensional tomographic analyses.

Secondary

MeasureTime frame
To evaluate the success, survival, and stability rates of dental implants placed in maxillary sinus lift sites grafted with different biomaterials, with or without the use of PRF. Four groups will be compared (PRF + Bio-Oss®, Bio-Oss® alone, PRF + Nanosynt®, and Nanosynt® alone), with an expected minimum detectable difference of 10% between groups. Outcomes will be assessed through standardized peri-implant clinical evaluation (probing depth, bleeding on probing, and plaque index), measurement of implant stability, and assessment of marginal bone levels using digital periapical radiographs.
