Summary

Different dental burs cause varying surface changes and material removal in titanium and zirconia implants. Careful instrument selection is crucial for implantoplasty to balance healing promotion and minimize damage.

Area Of Science

Biomaterials Science
Dental Implantology
Surface Engineering

Background

Titanium (Ti) and zirconia (Zr) are widely used dental implant materials.
Understanding instrumentation effects is vital for implant surface integrity and osseointegration.

Purpose Of The Study

To evaluate the impact of various instrumentation techniques on material removal and surface alterations.
To compare the effects of airflow, ultrasound, carbide, and diamond burs on Ti and Zr implant discs.

Main Methods

Standardized instrumentation of Ti and Zr discs for 60 seconds.
Assessment of abrasion and surface roughness using profilometry.
Examination of morphological changes and particle size via scanning electron microscopy.

Main Results

Carbide burs caused significant abrasion on Ti discs; diamond burs caused more abrasion on Zr discs.
Ti discs exhibited greater susceptibility to surface changes.
Machined Zr discs treated with diamond burs yielded the largest particles, with statistically significant differences noted in some comparisons.

Conclusions

Instrumentation techniques significantly alter the surface characteristics of Ti and Zr implant discs.
Carbide and diamond burs have distinct and notable effects on implant surfaces.
Choosing appropriate instruments for implantoplasty is essential to optimize healing and prevent adverse effects.
