The present research work aims to compare and establish the best resistance strength in in vitro procedure prior to cementation in bovine teeth when performing the treatment of metal brackets with abrasive air to different amounts of aluminum oxide microns; For this purpose an investigation of explanatory, Descriptive and correlational scope with experimental design was carried out, the sample was conformed by 60 units and in addition to the control group three experimental groups were established, of 60 µ, of 120 µ and of 200 µ of aluminum oxide. The conclusions show that: the resistance in vitro procedure prior to cementing the bovine teeth in metal brackets treated with abrasive air for 20 seconds at a distance of five centimeters with aluminum oxide of 60 microns was 7,962 ± 2,027 MPa; For the case of 120 microns it was 4,678 ± 0,905 MPa; And for the case of 200 microns it was 7.678 ± 0.644. The statistical difference with respect to the in vitro resistance to the removal of metal brackets related to ANOVA was verified. Using the Tukey post hoc test, we can see in the table that untreated teeth have similar in vitro resistance to the removal of metal brackets with the pieces Treated with abrasive air of 120 microns; But it is different with teeth treated with abrasive air of 200 microns and 60 microns. It is also noted that there is an in vitro resistance to metal bracket eviction similar between teeth treated with abrasive air at 200 microns and at 60 microns.
