Candidate patients for implant placement in the posterior region of the maxilla and maxillary sinus floor augmentation surgery.
Conditions
Interventions
Intervention 1: **Intervention Group:**In the surgical procedure for the intervention group, 2 cc of allogenic demineralized dentin matrix is placed. Teeth with a poor prognosis (such as non-functioni
enamel is removed with a burr.The remaining dentin is rinsed with sterile saline and processed in a bone mill to create particles sized 1 to 1.5 mm. These particles are washed in a 0.1 M sodium chlori

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The amount of newly formed vital bone. Timepoint: 6 months after maxillary sinus floor augmentation surgery. Method of measurement: Sampling is done with a Trephine bur with a diameter of 7.2 mm at the location of the implants. The collected samples are placed in 10% formalin solution and sent to the laboratory for histological examination. After routine and specific staining (Eosin and Hematoxylin and Red Alizarin), microscopic slides are prepared and after imaging with the help of Motic Image 2 software, the amount of newly formed vital bone is measured in square millimeters.;Amount of remaining grafting material. Timepoint: 6 months after maxillary sinus floor augmentation surgery. Method of measurement: Sampling is done with a Trephine bur with a diameter of 7.2 mm at the location of the implants. The collected samples are placed in 10% formalin solution and sent to the laboratory for histological examination. After routine and specific staining (Eosin and Hematoxylin and Red Alizarin), microscopic slides are prepared and after imaging with the help of Motic Image 2 software, the amount of the remaining graft material is measured in square millimeters.;Bone density. Timepoint: 6 months after maxillary sinus floor augmentation surgery. Method of measurement: Based on the Hounsfield number From the CBCT by soft App Mimics 10.01.;Bone height. Timepoint: 6 months after maxillary sinus floor augmentation surgery. Method of measurement: The difference in bone height from the crest of the ridge to the bottom of the sinus between before surgery and 6 months after surgery in the patient's CBCT. | — |
