Abutment Height Relates to Peri-Implant Bone Loss
While many factors impact implant surgery outcomes—from initial treatment planning and osseointegration to oral hygiene—researchers have now determined that prosthetic abutment height may also influence treatment success. In the retrospective cohort study, “Prosthetic Abutment Height Is a Key Factor in Peri-Implant Marginal Bone Loss,” published online in March in the Journal of Dental Research, an international study team found that abutment height may be a contributing factor leading to marginal bone loss around implants in the posterior maxilla.
To reach this conclusion, scientists from the University of Granada in Spain, University of Bologna in Italy, and the University of Michigan School of Dentistry in Ann Arbor evaluated data on 131 patients who received 315 implants. Information was gathered on age, sex, bone substratum, smoking habits, history of periodontitis, and prosthetic features. A linear mixed model was used for statistical analysis.
The researchers discovered that marginal bone loss rates at 6 months and 18 months post-implant surgery were affected primarily by abutment heights—though bone substratum, periodontitis, and smoking habits also played significant roles. The rate of marginal bone loss was higher for prosthetic abutments measuring more than 2 mm and followed a nonlinear trend, with the highest rates of marginal bone loss occurring in the first 6 months after surgery.
