Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In implant treatments, which have become widely used today, successful results depend on the ideal volume and quality of hard and soft tissues. The amount of bone present in the edentulous area is important for the indication of the implant.
The aim of this study is to evaluate the histological and immunohistochemical contribution of the H-PRF (horizontal-platelet rich fibrin) material placed in the extraction sockets to the quality of the newly formed bone tissue in order to make successful implants after tooth extractions for various reasons in humans.
The research hypothesis is that H-PRF will contribute positively to the healing of tooth extraction sockets.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Study inclusion criteria: Volunteer ASA I individuals between the ages of 18-40
Exclusion criteria for the study: Those who are pregnant or lactating Those receiving anticoagulant or antiplatelet drug therapy Those who received radiotherapy to the head and face area Those who are allergic to local anesthetics and prescribed medications
Considering possible losses, a total of 30 volunteers will be included in the study.
Randomization: Before the operation, patients will be divided into three groups: a control group, an L-PRF (leukocyte platelet-rich fibrin) group, and an H-PRF group. The sealed envelope method will be used in the process of assigning patients to the group. Sealed envelopes of the same color will be used for each group, and the patient will not know which group he is assigned to, but the physician will know which group the patient is assigned to.
Tooth extraction will be performed on patients in each group. CBCT (cone beam computed tomography) will be taken immediately afterwards. Soft tissue healing will be evaluated in the first 7 days. CBCT will be taken again after 3 months. Dental implant operations will be performed. Bone tissue biopsies will be taken after the operation. Biopsies are not routine procedures and will be obtained from bone tissue that will be removed during the operation.
Control Group (n=10): Patient group in which no material was placed in the extraction socket after tooth extraction. There will be 10 patients in this group.
L-PRF (Comparison Arm): The patient group in which L-PRF will be placed in the extraction socket after tooth extraction. There will be 10 patients in this group. Patients will be called on the 2nd and 7th days, and their conditions will be evaluated.
H-PRF (Research Branch): The patient group in which H-PRF will be placed in the extraction socket after tooth extraction. There will be 10 patients in this group. Patients will be called on the 2nd and 7th days and their conditions will be evaluated.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
CONTROL GROUP
Control Group (n=10): Patient group in which no material was placed in the extraction socket after tooth extraction.
No interventions assigned to this group
L-PRF (leukocyte-platelet rich fibrin)
L-PRF (Comparison Arm): The patient group in which L-PRF will be placed in the extraction socket after tooth extraction.
L-PRF
Blood will be taken from the patient before the surgical procedure is started. The blood sample will be placed in the L-PRF device for centrifugation and the sample will be centrifuged. (2700M x 12 min, 700g) After the blood is processed for centrifugation, the surgery will begin. Surgery will be performed under local anaesthesia with articaine 2 ml 4% and epinephrine 1:100,000. All patients will be operated by the same surgeon. After local anaesthesia is achieved, tooth extraction will be started. After tooth extraction, the surgical field will be washed with sterile 0.9% saline, and L-PRF material will be placed in the area and primarily sutured with a 3.0 silk suture. All patients will be given postoperative instructions by the surgeon. Patients will be prescribed mouthwash (0.12% chlorhexidine mouthwash twice daily for 7 days).
H-PRF (horizontal-platelet rich fibrin)
H-PRF (Research Branch): The patient group in which H-PRF will be placed in the extraction socket after tooth extraction.
H-PRF
Blood will be taken from the patient before the surgical procedure is started. The blood sample will be placed in the H-TZF device for centrifugation and the sample will be horizontally centrifuged (2200 RPMx8 min, 700g). After the blood is processed for centrifugation, the surgery will begin. Surgery will be performed under local anesthesia with articaine 2 ml 4% and epinephrine 1:100,000. All patients will be operated by the same surgeon. After local anesthesia is achieved, tooth extraction will be started. After tooth extraction, the surgical field will be washed with sterile 0.9% saline, and H-PRF material will be placed in the area and primarily sutured with a 3.0 silk suture. All patients will be given postoperative instructions by the surgeon. Patients will be prescribed mouthwash (0.12% chlorhexidine mouthwash twice daily for 7 days).
