Summary
Dental implant surface topography changes after bone insertion. Bone residues covered surfaces, indicating that surface modifications are less critical than TiO2 layer reestablishment for osseointegration.
Area of Science:
- Biomaterials Science
- Dental Implantology
- Surface Engineering
Background:
- Dental implants are crucial for restorative dentistry.
- Implant surface design significantly impacts primary healing.
- The sandblasted and acid-etched (SLA®) surface is widely used.
Purpose of the Study:
- To evaluate the morphological integrity of SLA® implant surfaces post-insertion into human bone.
- To determine if the SLA® surface is affected by the bone insertion process.
Main Methods:
- Six SLA® dental implants were inserted into two human jaw specimens.
- Two control implants were not inserted.
- Explanted implants were examined using Scanning Electron Microscopy (SEM) for surface changes, with some left uncleaned.
Main Results:
- Significant topographic alterations were observed on the apical thread flanks of all inserted implants.
- Uncleaned implants exhibited extensive surface coverage by bone residues, forming a honeycomb-like structure.
- Control implants showed no surface modifications.
Conclusions:
- Subtractive surface modifications may be less critical for osseointegration than restoring the titanium dioxide (TiO2) layer.
- Further research on diverse implant surfaces is necessary to validate these findings.
