Impact on Implant`s Surface Roughness Using Titanium Scalers
Objectives: To determine optimized contact forces using titanium scalers to remove cement remnants from titanium implant abutments without damaging the surface during the scaling procedure.
Methods: The smooth cervical surfaces of Straumann tissue level implants were scaled using a titanium scaler. Implants and scaler were placed in a motor driven device, which allowed exact reproducible scaling procedures with various adjustable contact forces. The scaler treated the implant 10 times per rotation (R). Each implant rotated with 1R/min once. Contact forces of the scaler from 1.5N to 3N, 4.5N, 6N and 10N as well as a control group (untreated surfaces) were investigated. The surface roughness Ra and Rz after scaling and of the control group were examined using a 3D laser scanner with 50x magnification. Statistics: means, std.dev., t-test, α=0.05.
Results: The results showed no statistically significant increase of surface roughness values Ra and Rz for the smooth titanium implant surfaces scaled with a contact force of 10N and lower. In contrast, contact forces below 4.5N smoothen the surface significantly. (Table 1)
Conclusions: The use of titanium scalers to remove cement remnants from titanium abutments did not necessarily damage the titanium surface. Further investigations with the motor driven device using various luting agents or different hygene protocols should be carried out to develop various cleaning concepts in the future.
