Clinical, Radiographical, Histological Evaluation and Blood Flow Analysis of Alveolar Ridge Preservation

This study evaluates a technique called alveolar ridge preservation (ARP) — a procedure done at the time of tooth extraction to maintain the shape and volume of the jawbone so it can support a dental implant later. The study compares different ARP approaches using clinical measurements, X-rays, tissue analysis, and blood flow data to determine which technique best preserves bone after tooth removal. **You may be eligible if...** - You are 18 or older - You have good individual oral hygiene (FMBS below 25%) - You are in treatment or under treatment for periodontal disease with minimal active inflammation (FMPS below 25%) - You have a tooth that needs to be extracted due to advanced periodontal or endo-periodontal disease, which will be replaced with a dental implant **You may NOT be eligible if...** - You have an active infectious disease (HIV, hepatitis B or C, COVID-19, etc.) - You are currently receiving chemotherapy or radiation therapy - You have had radiation to the head or neck in the past 2 years - You have untreated insulin-dependent diabetes - You have significant osteoporosis or bone-affecting systemic disease - You have severe heart disease, decompensated heart failure, or had a heart attack in the past 3 months - You have significant clotting disorders - You are on corticosteroids (in the past 2 months) or bisphosphonates (more than 30 days) - You are pregnant or breastfeeding - You smoke more than 5 cigarettes per day - You have a drug or alcohol addiction **Talk to your periodontist or oral surgeon if** you need a tooth extracted and are planning to get a dental implant, and want to learn about bone-preserving techniques that can improve implant success.
