Greater bone regeneration required for implants following periodontal extraction: a retrospective cross-sectional study

Abstract

Background: We evaluated cone beam computed tomography images to compare the complexity of dental implant surgery after alveolar ridge preservation in damaged versus intact sockets resulting from severe periodontitis-related tooth extraction. Methods: In a retrospective analysis of 165 alveolar ridge preservation sites among 116 patients, we categorized 72 sockets as damaged and 93 as intact. Using cone beam computed tomography, we measured bone width at three vertical levels and compared bone regeneration needs for subsequent dental implant surgery between socket types. Results: Despite no difference in bone width between damaged and intact sockets, implant placement revealed differing regenerative needs. Mandibular teeth and non-drinkers required less regeneration. Damaged sockets exhibited 3.02 times higher regeneration requirements compared to intact ones. Conclusions: The complexity of implant surgery following alveolar ridge preservation is influenced by alcohol consumption, tooth position, and periodontitis-related tooth extraction.
