Autologous Blood Products in Ridge Preservation

This randomized controlled clinical trial aims to evaluate the clinical, radiographic, and ultrasonographic outcomes of alveolar ridge preservation using autologous blood products following tooth extraction. After tooth extraction, dimensional changes occur in both hard and soft tissues, which may negatively affect future implant or prosthetic treatments. This study investigates whether the application of Titanium Platelet-Rich Fibrin (T-PRF), combined with injectable Platelet-Rich Fibrin (i-PRF), can improve healing and reduce tissue changes. In this study, tooth extraction will be performed under local anesthesia using minimally invasive techniques. Autologous blood will be collected from the patient and processed by centrifugation to obtain T-PRF and i-PRF. The prepared materials will be applied to the extraction socket and stabilized with sutures. Healing will be monitored through clinical examinations, radiographic imaging, and ultrasonographic evaluations over a 6-month follow-up period. Possible risks include pain, bleeding, infection, and temporary discomfort, all of which are manageable with standard clinical care. The study is expected to contribute to the development of biologically based, minimally invasive treatment approaches that enhance tissue healing and support future dental treatments.

Comparison of Two Types of Bone Grafts in Patients Who Need One of Their Front Teeth Removed and Replaced With an Implant

The purpose of this study is to compare two different bone graft materials (freeze-dried bone allograft, FDBA and collagen-enriched bovine xenograft, CEBX) that are routinely used for preserving the remaining bone after extraction of an anterior tooth, and before placing a dental implant. Patients will be randomly assigned to either group (flip of a coin) One group will receive FDBA material and the other group will receive CEBX (cow) material. The study aims to examine the following main questions: * Potential differences in linear radiographic horizontal (HRD) and vertical (VRD) ridge dimensional changes between groups after 16 weeks of healing * Other clinical information of the treated areas and information regarding the esthetics of the dental implant that will subsequently be placed at the edentulous site as well as patient satisfaction with the treatment, will be evaluated. The study will include 7 study visits. Study procedures will take place during the same visits as the standard of care treatments (tooth extraction and bone graft, dental implant placement, crown installation and follow-ups). Clinical information from these standard of care visits will be used for the current research study, such as: * Demographic information * Clinical information from intraoral photographs * Radiographic information from cone beam computed tomography and periapical radiographs.
