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

Attending Physician, Division of Periodontics, Department of Dentistry, Kaohsiung Medical University Hospital, Kaohsiung

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

Study Overview

• Status: Completed
• Conditions: the Complexity of Implant Surgery

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.

• Study Type: Observational
• Enrollment (Actual): 165

Study Population

Of 165 sites, dental implant surgery was performed at 156 sites. A total of 72 damaged sockets and 93 intact sockets were included.

Description

Inclusion Criteria:

• teeth extraction in the premolar and molar regions, who underwent flapless tooth extraction with alveolat ridge preservation (ARP) and filling with freeze-dried bone allograft (FDBA) and platelet-rich fibrin (PRF), who underwent cone beam computed tomography (CBCT) followed by dental implant surgery after tooth extraction, and with adequate oral hygiene

Exclusion Criteria:

• untreated periodontitis, systemic disease, or the of medication that influences bone metabolism
