Sinus Lift
Conditions
Brief summary
Trephine osteotomy was used for lateral sinus lifting technique associated with sinus floor augmentation using the autogenous bone resulting from implant drilling using specialized trephine drills.
Detailed description
The study includes 14 patients in whom the lateral sinus lift technique was performed using the trephine osteotomy with simultaneous implant placement. Sinus floor augmentation with autogenous bone graft resulting from implant site preparation with trephine drills. Implant stability and rate of complications such as Schneiderian membrane perforation and bleeding will be assessed. Patients will also provide their subjective assessment of postoperative pain and swelling. Vertical bone height, that will be gained, will be assessed radiographically
Interventions
PROCEDURETrephine osteotomy
* Using a trephine on a straight implant handpiece (at approximately 1800 rpm) with copious irrigation to avoid overheating the bone, a round bone cut will be made 4 -5 mm above the crest of the alveolar ridge. * The trephine is positioned perpendicular to the lateral wall, removing the outer cortex with a very gentle touch to avoid tearing the schneiderian membrane.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Implant stability | at baseline and 6 months | This will be measured by implant stability meter (OsstellTM) |
| change in bone density | at baseline, 3rd and 6th months | Panoramic radiography will be performed immediately postoperatively and cone beam computed tomography (CBCT) |
| change in bone volume | at baseline, 3rd and 6th months | Panoramic radiography will be performed immediately postoperatively and cone beam computed tomography (CBCT) |
| change in bone vertical bone height | at baseline, 3rd and 6th months | Panoramic radiography will be performed immediately postoperatively and cone beam computed tomography (CBCT) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| post operative pain | after 1 week | This will be assessed using a 10-point Visual Analogue Scale (VAS) in the 1st week postoperatively. (0-1=None, 2-4=Mild-Moderate, 8-10= Severe) |
| Postoperative edema | after 1 week | * 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 |
