Detailed Description
In addition to insufficient bone height with bone resorption of the posterior maxilla after tooth loss, the pneumatization of the maxillary sinus is one of the factors that prevent implant placement in the posterior maxilla. For this, it is necessary to raise the sinus mucosa from the sinus floor (sinus lift) and to provide new bone formation by using bone graft materials (maxillary sinus augmentation) in the resulting sinüs cavity. Two-stage sinus augmentation and implant placement have been recognized as a good clinical model for evaluating the performance of graft materials. Because bone formation takes place in a closed area and with minimal intervention of external factors. Platelet-rich fibrin (T-PRF) prepared with titanium from autologous thrombocyte concentrates showed a tighter polymerized fibrin structure and a long dissolution process, and it was reported that new bone formation started on the 15th day with the placed T-PRF and was effective in 30 days. In a study, comparing the use of allograft and T-PRF in maxillary sinus augmentation, the group in which only T-PRF was applied showed successful clinical and histological results, and new bone formation was accelerated up to 4 months compared to allografts. The primary stability of the implants placed was similar in both groups.
The primary stability of the implant, the bone histology, volume, height and density of the two-stage sinus lift in the bilateral maxillary posterior region with insufficient bone height with tooth deficiency, and the placement of platelet-rich fibrin prepared with titanium on one side and bovine bone graft on the other side in implant surgery, evaluation of its effect.
Bilateral atrophic maxilla dental implant placement and who needed maxillary sinus augmentation, and who did not smoke or smoked at most 10 cigarettes will be included in the study. Before the operation, systemic and dental anamnesis will be taken from the patient and clinical measurements and radiographic images will be recorded.
Inclusion criteria
- be over 18 years old
- The patient does not have any systemic disease
- Patients who do not smoke or smoke less than 10 times a day
- Patients who need fixed implant supported prosthesis in the bilateral maxillary posterior region
- Bilateral posterior maxilla residual bone height <5 mm on current radiographs
- Full mouth plaque insertion and bleeding score ≤15%
Exclusion criteria
- Being outside the specified age range
- Patients who smoke more than 10 cigarettes a day
- History of acute infection or chronic sinusitis in the Schneiderian membrane
- Having allergies involving the respiratory system
- Any contraindication for systematic periodontal surgery (Patients with bleeding platelet disorders, bisphosphonate therapy, uncontrolled diabetes (HbA1c > 6%, blood glucose level > 110 mg/dl)),
- Bilateral posterior maxilla residual bone height >5 mm on current radiographs
- Full mouth plaque insertion and bleeding score ≥15% Bio-oss bovine bone graft on one side and platelet-rich fibrin prepared with titanium on the other side of 10 patients who require bone height increase with the maxillary sinus augmentation procedure for implant placement in the atrophic posterior maxilla with a bilateral bone height of less than 5 mm will be applied. Test group and Control group will be written in closed envelopes, and platelet-rich fibrin prepared with titanium groups and Bio-oss bovine bone graft will be selected randomly.
The operation date will be given after the patient is given oral hygiene training and 4 weeks after receiving Phase I routine periodontal treatment. The data to be obtained preoperatively and postoperatively are as follows:
- Plaque index (Löe&Silness): It is obtained by measuring with a periodontal probe from 4 regions of a tooth (mesial, distal, buccal and lingual).
- Gingival index (Silness&Löe): It is obtained by measuring with a periodontal probe from 4 regions of a tooth (mesial, distal, buccal and lingual).
- Attachment loss: The distance between the free gingiva and the base of the periodontal sulcus, based on the enamel-cementum boundary of a tooth, is measured using a periodontal probe.
- Bleeding index on probing (Ainamo & Bay): In this index, probing is performed by gently walking around the pocket. As a result of probing, the evaluation is made by looking at the presence or absence of bleeding in the gingiva. A positive value is given if bleeding occurs within 10-15 seconds after probing in the mesial, distal, buccal and lingual gingival parts of all teeth. The ratio of the bleeding area to the examined area is expressed as %.
- Pocket depth: It is the vertical distance measured between the base of the periodontal sulcus and the gingival margin with a standard periodontal probe
- Residual bone height: It is the distance from the top of the alveolar crest to the floor of the maxillary sinus in the preoperative tomography.
- Sinus mucosal thickness: It is the measurement of the membrane's sinus floor and adjacent surfaces of the sinus cavity. Its thickness varies between 2.16-3.11.
- Sinus volume: It is the measurement of the vertical and horizontal heights of the sinus cavity.
- Fractal analysis: By placing circles of various diameters randomly in the image, the pixels of the image border inside the circles are counted. It is stated that it reflects changes in trabecular bone density and mineral loss in bone. When the panoramic radiographs were examined with fractal analysis, it was stated that the increase in the fractal size of the bone around the implant correlated with successful osteointegration and healing of the trabecular bone.
- Hounsfield unit: System computers assign a number to all voxels in the images obtained by computed tomography according to this scale. It is to paint voxels that have received numerical values with black, white and gray tones in between that match the numbers they receive. Changes in bone can be observed

Experimental: Bio-oss bovine bone graft with maxillary sinus augmentation and implant placement
A 2 cc Bio-oss bovine bone graft will be used for maxillary sinus augmentation before placing an implant on one side of the bilateral atrophic maxillary posterior regions.
Then, 6 months after the surgery, the implant will be placed in accordance with the standard protocol

For maxillary sinus augmentation, the area will be prepared by lifting a full-thickness flap.
The sinus membrane will be carefully elevated by opening a window through the lateral wall of the sinus on both sides.
Bio-oss bovine bone graft on one side will be placed in the space prepared in the sinus region by random selection.
For Platelet-rich fibrin prepared, the blood taken from the patient to a 20 cc injektor was put into titanium tubes and prepared by centrifugation at 2700 rpm for 13 minutes according to the standard protocol.
Then, 6 months after the surgery, histological sample will be taken with a trephine bur in both groups and the implant will be placed in accordance with the standard protocol.
The stability value (ISQ) of the placed implant will be measured with the Ostell device at the time the implant is placed and 3 months after it is placed.
