Biomechanics and peri-implantitis: The effect of a subcrestal wing-thread to decrease alveolar crestal bone strain.
Summary
A novel wing-thread dental implant design may reduce bone loss around implants. Finite element analysis and a 30-month clinical study suggest this design enhances peri-implant bone stability under functional forces.
Area of Science:
- Biomaterials Science
- Dental Implantology
- Biomechanics
Background:
- Crestal bone loss is a significant concern in dental implantology, potentially leading to implant failure.
- Understanding the biomechanical factors influencing peri-implant bone stability is crucial for improving implant longevity.
Purpose of the Study:
- To test the hypothesis that a wing-thread implant design, placed 4 mm below the implant shoulder, reduces crestal bone loss.
- To evaluate the biomechanical effects of a wing-thread design on stress distribution at the alveolar crest.
Main Methods:
- Finite element analysis (FEA) was employed to compare stress distribution between standard and wing-thread implant designs under axial and off-axis forces.
- A clinical case study followed a patient with wing-thread implants for 30 months to assess bone stability.
Main Results:
- FEA demonstrated reduced stress concentration at the alveolar crest with the wing-thread implant compared to standard designs.
- Lateral forces at 90 degrees were reduced by a factor of 10 with the wing-thread implant.
- Clinical follow-up showed stable peri-implant bone levels around the wing-thread implants over 30 months.
Conclusions:
- The wing-thread implant design shows potential for enhancing peri-implant bone stability.
- Both finite element analysis and early clinical data support the efficacy of the wing-thread design in mitigating crestal bone loss.
