Evaluation of Post Extraction Hard Tissue Changes Following Ridge Preservation in the Esthetic Zone Using Allogeneic Dentin Matrix Versus Autogenous Partially Demineralized Dentine Matrix

What this Trial Is About

Researchers are studying how well two types of dentin matrix grafts help preserve the bone after tooth extraction in the smile area, called the aesthetic zone. The study compares an allogenic dentin matrix, which is processed from donor teeth, with an autogenous partially demineralized dentin matrix (APDDM), made from the patient's own extracted tooth. The goal is to see which method better reduces hard tissue changes and supports bone healing. This clinical trial is randomized and controlled to provide reliable comparisons. The allogenic dentin matrix undergoes a detailed cleaning and processing procedure including washing, ultrasonic cleaning, defatting, demineralization, dehydration, freeze-drying, and sterilization before being placed in the extraction socket. The autogenous dentin is cleaned, ground using a special device, partially demineralized, and then packed into the socket. Both groups have the graft covered with a collagen membrane that is secured with sutures. After six months of healing, a biopsy sample will be collected during implant placement to evaluate the bone formation. Participants will visit the clinic for periodontal and radiographic exams before treatment. After tooth extraction and graft placement, they will be monitored over a six-month period, including radiographic imaging to measure bone changes and bone width loss. Researchers will also assess vital new bone formation, the presence of residual graft material, and the stability of dental implants placed later. This study involves outpatient visits and tissue sampling to fully understand the healing outcomes.
