About this trial
This clinical investigation aims to assess how two different allogeneic dentin graft materials - one de-mineralized and the other mineralized - influence bone preservation following extraction of a single upper posterior tooth. A total of 45 patients will be randomly allocated into three equal groups: a socket-only spontaneous healing group (control), a de-mineralized dentin graft group, and a mineralized dentin graft group. Over a six-month period after extraction, measurements will be taken using CBCT to monitor changes in ridge width, height, and bone density. Secondary outcomes include patient-reported pain, postoperative swelling, satisfaction levels, width of keratinized tissue, and histomorphometric data from biopsy samples at implant placement. Findings from this trial may support evidence-based decisions in alveolar ridge preservation and help clinicians choose the most predictable grafting strategy before implant placement.

Treatments tested in this trial
Demineralized Allogeneic Dentin Graft
Biological/VaccineParticulate demineralized allogeneic dentin processed from donor teeth using standardized laboratory protocols, including cleaning, defatting, demineralization, dehydration, freeze-drying, and sterilization. The graft is placed into the extraction socket following atraumatic extraction, covered with a resorbable collagen dressing, and the site is closed to promote alveolar ridge preservation.
Mineralized Allogeneic Dentin Graft
Biological/VaccineParticulate mineralized allogeneic dentin derived from processed donor teeth. The dentin is cleaned, defatted, ultrasonically treated, dehydrated, freeze-dried, and sterilized while retaining its mineral phase. The graft is inserted into the extraction socket after atraumatic extraction and covered with a resorbable collagen material prior to closure to support ridge preservation.
Treatment groups
Trial outcomes
Primary outcomes
Change in Alveolar Ridge Width (Buccolingual Dimension)
Measurement of the buccolingual width of the alveolar ridge using standardized Cone-Beam Computed Tomography (CBCT). Width is measured at predetermined reference points to assess dimensional bone changes following grafting.
Change in Alveolar Ridge Height (Vertical Dimension)
Vertical height of the alveolar ridge measured radiographically on CBCT at standardized anatomical landmarks to quantify bone height changes over the healing period.
Bone Density at the Grafted Site
Bone density at the extraction site measured using CBCT expressed in Hounsfield Units (HU) to evaluate bone quality gained after grafting
Secondary outcomes
Postoperative Pain Levels (VAS Score)
Postoperative pain will be evaluated using a Visual Analog Scale (VAS) ranging from 0 to 10, where 0 indicates no pain and 10 indicates severe pain. Participants will record pain levels at predefined postoperative intervals.
Postoperative swelling
Facial swelling will be assessed through standardized digital facial photographs taken at each time point. Facial dimensions will be analyzed using image analysis software to quantify postoperative edema.
Patient Satisfaction Score
Patient satisfaction will be recorded using a structured questionnaire that scores satisfaction on a scale from 0 to 4 (0 = very satisfied, 4 = very dissatisfied). Participants will complete the questionnaire at designated follow-up intervals.
Width of Keratinized Tissue
Keratinized tissue width will be measured using a UNC-15 periodontal probe at the buccal aspect of the site. Measurements will be taken at baseline and during the final follow-up to assess changes associated with socket healing.
