Factors Associated With the Complexity of Dental Implant Surgery After Alveolar Ridge Preservation: A Retrospective Cross-sectional Study

Completed

• Conditions: the Complexity of Implant Surgery

• Registration Number: NCT05657223
• Lead Sponsor: Kaohsiung Medical University Chung-Ho Memorial Hospital

Brief Summary

Alcohol consumption, tooth position, and periodontitis-related tooth extraction affect the complexity of subsequent implant surgery after alveolar ridge preservation.

Detailed Description

Materials and methods We retrospectively analyzed the dentition of 165 alveolar ridge preservation sites in 116 patients. The bone width at three different vertical levels was measured on cone beam computed tomography images, and a comparison of bone regeneration requirements for subsequent dental implant surgery was performed for different socket types.
