Sinus Floor Augmentation, Graftless Sinus Elevation
Conditions
Keywords
Tenting implant, Fibrin glue, T-PRF
Brief summary
Graftless sinus lift with simultaneous implant placement is one of the new techniques, this new technique is presented based on the physiology of intrasinus bone repair. Schneiderian membrane is known to have an osteogenic nature, now blood clot can be considered autologous osteogenic graft material, to which osteoprogenitors can migrate, differentiate, and regenerate bone. The aim of this study is to evaluate the effectiveness of using Fibrin glue versus Titanium platelet rich fibrin (T-PRF) as a sole filling material in lateral sinus lifting using with simultaneous implant placement in comparison to a negative control group.
Interventions
OTHERFibrin Glue
Blood samples were collected from the antecubital vein of the right or left arm of the patient and drawn into sterile Titanium tubes immediately. The tubes were then centrifuged for 12 minutes at 2800 rpm and room temperature
OTHERT-PRF
The contents of the two containers (human fibrinogen, human thrombin) will be mixed with distilled water and then aspirated by two syringes after that, the two solutions will be mixed together and injected into the empty compartment around the dental implant under the sinus mucosal lining using auto mixing applicator.
OTHERNegative control
this group will not receive any material.

Exclusion criteria
* Maxillary sinus pathologies (sinusitis, long-standing nasal obstruction). * Any disease-contraindicating surgery (e.g. uncontrolled diabetes). * Heavy smokers (smoke greater than or equal 25 cigarettes daily). * Acute oral infections. * Untreated periodontal disease (gingival index 2 and 3). * Poor oral hygiene ( Silness-Löe index (score 2-3) ). * A history of radiotherapy or chemotherapy of the head and neck region. * Pregnancy.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| change in implant stability | Baseline and 6 months | implant stability will be measures using Ostell device. |
| change in bone density | Baseline and 6 months | bone density will be measured using CBCT |
| change in vertical bone height | Baseline and 6 months | vertical bone height will be measured using CBCT |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| change in pain intensity | Through 1 week postopertaive | This will be assessed using a 10-point Visual Analogue Scale (VAS) in the 1st week postoperatively. (0-1= None, 2-4= Mild, 5-7= Moderate, 8-10= Severe) |
| Change in edema score | Through 1 week postopertaive | The score will be as follows: * None (no inflammation) * Mild (intraoral swelling confined to the surgical field) * Moderate (extraoral swelling in the surgical zone) * Severe (extraoral swelling spreading beyond the surgical zone) |
