Efficiency of PRGF-Endoret in Combination With a Bone Graft in Lateral Sinus Floor Elevation
Study Details
Study Description
Brief Summary
This randomized clinical study investigates the efficiency of plasma rich in growth factors (PRGF-Endoret) in combination with bone grafts in the healing of bone and soft tissues after the performance of lateral sinus floor elevation.
The hypothesis of this study is that the use of PRGF-Endoret will produce similar bone formation regardless the type of bone graft.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Bio-Oss the xenograft is of bovine origin where the organic phase has been eliminated. |
Device: Bio-Oss
It is a bone substitute of bovine origin
|
| Experimental: calcium phosphate ceramic is a calcium phosphate biomaterial |
Device: calcium phosphate ceramic
It is a synthetic bone substitute ceramic that is composed of calcium and phosphate ions and prepared at high temperature

Outcome Measures
Primary Outcome Measures
- Percentage of newly-formed bone [6 months after surgical intervention]
The histomorphometrical analysis of the biopsies taken after 6 months of surgical intervention (time for dental implants insertion) will be performed to calculate the primary outcome
Secondary Outcome Measures
- Bone density [at baseline and after 6 months of intervention]
This data will be measured on the cone-beam CT scanners obtained at baseline and after 6 months of healing
- Insertion torque [6 months after surgical intervention]
At the time of implant insertion and initial insertion torque will be registered
- Percentage of residual graft [6 months after surgical intervention]
The histological analysis will determine the percentage of residual graft after 6 months of surgery.
- Pain index [7 days, 15 days, 1 month, 2 months, 6 months and 12 months after surgical intervention]
This will evaluate the intensity of pain the patient suffered due to the surgical intervention.
- Healing index [7 days, 15 days and 1 month after surgical intervention]
This index will evaluate the soft tissue healing.
- Infection [7 days, 15 days, 1 month, 2 months, 6 months and 12 months after surgical intervention]
Notify the infection of the graft material
