title: Analysis of Effectiveness of Different Rotational Instruments in Implantoplasty: An In Vitro Study.
abstract: OBJECTIVE
  To analyze the temperature increase in the implant, adjacent bone, procedure time, and roughness provided by different rotatory instruments in the implantoplasty procedure.
  
  
  METHODS
  Three types of rotational instruments were used to evaluate the implant surface wear, divided according to their surface features: Group 1 (G1) diamond, Group 2 (G2) tungsten carbide, and Group 3 (G3) multilaminar. For the roughness test, a control group was included for comparison with the test groups.
  
  
  RESULTS
  The temperature variation was statistically significant in the implant (P < 0.05) where G2 showed the lowest variation. There was no statistically significant difference between the 3 groups regarding the temperature increase measured in the bone (P > 0.05). The difference of wear time was statistically significant (P < 0.05) with faster results for G3. In the surface roughness analyses, there was a statistically significant difference (P < 0.05) between the control group and the test groups. Among the 3 test groups, the difference between measurements was not statistically significant (P > 0.05).
  
  
  CONCLUSIONS
  All tested rotatory instruments performed the same level of surface roughness in the implantoplasty. The tungsten carbide bur caused a minor change in the implant temperature. The multilaminar bur performed a faster wear time. More in vivo studies are necessary to conclude which is the best rotatory instrument for implantoplasty.
