Summary

Platform-switching dental implants demonstrate excellent long-term success. This prospective study found minimal crestal bone loss around these implants after 11–14 years, confirming their efficacy in preserving bone levels.

Area of Science:

  • Dental Implantology
  • Periodontology
  • Biomaterials Science

Background:

  • The platform-switching concept in dental implants involves using components with different diameters to create a microgap, potentially influencing crestal bone levels.
  • Long-term data on the efficacy of platform-switched implants in preserving crestal bone is crucial for clinical decision-making.

Purpose of the Study:

  • To prospectively evaluate implant survival and crestal bone levels around platform-switched dental implants.
  • To assess the long-term (minimum 11 years) outcomes of platform-switching in dental implantology.

Main Methods:

  • Prospective study design involving 94 platform-switched dental implants.
  • Radiographic evaluation of crestal bone levels 11 to 14 years after loading.
  • Measurement of bone loss relative to the implant platform using thread pitch as a reference (0.8 mm).

Main Results:

  • High implant survival rates observed (specific percentage not detailed in abstract).
  • Significant preservation of crestal bone: 75.5% mesial and 71.3% distal aspects showed no bone loss.
  • 84% of mesial and 88% of distal surfaces exhibited 0.8 mm or less of bone loss.

Conclusions:

  • Platform-switching is an effective concept for preserving crestal bone levels around dental implants.
  • This study provides the longest prospective follow-up data supporting the long-term benefits of platform-switching.
  • The findings confirm the clinical efficacy of platform-switching for maintaining marginal bone stability.
