ClinConnect Summary

The study will be performance in 12 patients submitted to a bilateral sinus lift procedure.

Six months after the bilateral sinus lifting performed in a randomly way, using as graft materials (100% of autologous bone graft or 100% of xenograft), will be placed 1 to 3 implants in each maxillary sinus.

Wait more six months to expose the implant. At the end of 13 months after implant placement it should be in charge.

Implant placement (6 months after sinus lift procedure):

* Both sides should be treated during the same session.
* Patients will receive 2g Amoxicillin one hour before the proc...
