Risk Factors Associated With Peri‐Implant Marginal Bone Loss Among Japanese Patients Receiving Supportive Periodontal Therapy: A 10‐Year Retrospective Study

Key Points

• To identify risk factors contributing to marginal bone loss around dental implants in patients undergoing supportive periodontal therapy.
• Conducted a 10-year retrospective analysis of patients receiving supportive periodontal therapy.
• Examined medical and dental histories, including diabetes and periodontitis.
• Analyzed jaw position, keratinized mucosa width, and prosthetic features.
• History of diabetes is linked to increased marginal bone loss.
• Previous periodontitis is associated with higher risk of peri-implant bone loss.
• Jaw position and insufficient keratinized mucosa width also contribute to risk.
• Certain prosthetic features like fixation type influence marginal bone health.
