Titanium Surface Analysis after Instrumentation with Different Burs Simulating the Implantoplasty Technique: A Pilot In Vitro Experimental Study

(1) Background: The present pilot in vitro study evaluated, physically and biologically, the effects produced by wear of titanium surface using different drill models. (2) Methods: Titanium disks were subjected to four burs accordingly divided into following test groups (n = 12 per group): Tungsten Burs (TB group), Carbide (TCB Coarse-Grained Diamond (CGB Fine-Grained (FGB group). As a control group (CON with smooth (machined) used. samples atomic force microscopy (AFM), profilometry analysis, scanning electron (SEM), cell viability adhesion assessments. (3) Results: values measured roughness parameters showed statistical differences among five (p 0.0035 for Ra p 0.0010 Rz).
