• Registration Number: NCT06604819

Brief Summary

Purpose: The present study was conducted to evaluate the effect of using ozone gel with maxillary sinus elevation using tenting technique on the clinical and radiographic outcome of implants placed simultaneously..

Materials and Methods: A total of 30 sinuses with an average residual alveolar bone height ranging from 4-7 mm participated in this randomized controlled clinical trial. After closed sinus lift operation, patients were randomly and equally allocated into control group and ozone gel recipient group. Cone beam computed tomography was performed immediately and at 4 months postoperatively. Bone stability was measured immediately and at 3 \& 4 months postoperatively. Bone height and stability were evaluated radiographically, and bone stability was measured using the Osstell device.

Detailed Description

Concern over biological augmentations used in bone healing has grown in recent years. One of the essential demands in sinus lifting procedure is to speed up the bone formation and enhance the quality of the formed bone in the space created after sinus elevation. Since more than 100 years medical grade ozone has been used as one of the non-medication methods of treatment. E. A. Fisch in the 1930's was the first dentist to use ozone therapy in his practice to aid in disinfection and wound healing. Current ozone uses a mixture of ozone gel and pure oxygen, with today's medical ozone generators which regulate the flow of medical grade O2 through high voltage tubes which is capable of producing pure ozone-oxygen mixtures in precise dosages.

Nevertheless, there is not enough evidence to support the use of ozone in oral and maxillofacial surgery. Ozone therapy has a therapeutic effect that promotes blood and growth factor supply, aids in wound healing, and may improve bone regeneration . However up till now, no studies were conducted to assess the impact of using ozone gel on bone formation in case maxillary sinus elevation.

Arm && Interventions

Group	Intervention	Description
closed sinus lifting using osteotomes with simultaneous implant placement with ozone gel placement	Ozone gel placed after closed sinus lifting then implant placed simultaneously.	Full thickness mucoperiosteal flap was elevated.• The pilot drill of the implant system was used to create an osteotomy 1 mm short of the subantral floor. • The insertion of the osteotome were repeated several times until the required membrane lift was achieved then the osteotome corresponding in size to the last drill was used.Ozone gel was delivered into the osteotomy . To obtain the ozone gel, pure olive oil was blasted with 25 μ/ml O3 gas for two days, or until the oil changed from a greenish-colored liquid to a whitish gel. The longevity Ext 120 ozone generator executed out this process. After that, placement of the implant was done .Healing abutment was placed to allow for multiple times measurements of implant stability and primary closure was done and the flap was sutured in an interrupted manner using 4/0 prolene suture .

Primary Outcome Measures

Name	Time	Method
Implant stability	Immediate postoperative,3 months and 4 months postoperative	- Resonance frequency analysis was performed to assess implant stability. The implant stability was measured using the Osstell ISQ scale "immediate postoperative then after 3 and 4 months . The readings were taken along the three surfaces of the implant (perpendicular to the implant axis, mesial surface and distal surface). Finally, the averages of these readings were taken as a representative value for each implant .

Secondary Outcome Measures

Name	Time	Method
Bone Density	Immediate postoperative and 4 months postoperative	The bone density was evaluated using CBCT. To minimize the error from radiographic image alignment, the On Demand 3D fusion module software was used to generate a superimposed image at the sagittal and coronal planes of each implant to compare each parameter .
Bone height gain	Immediate postoperative and 4 months postoperative	Cone beam computed tomography (CBCT was taken to evaluate the accuracy of implant placement and to represent the baseline measurement for evaluation. The bone height gain was evaluated along the surface of each implant.
