Process for Treatment of the Surface of a Dental Implant

A processes for treating the surface of a dental implant, having an internal and an external screw, the process comprising the steps of:

• (1) cleaning the internal screw of the implant, wherein the implant is immersed in a washing solution with D'Limonemo, in average heated concentration of 3:50, pressurized for a period of time of about 20 to 30 minutes;
• (2) cleaning the external screw of the implant a first time, wherein the implant is immersed in a washing solution with D'Limonemo, in average heated concentration of 3:50, pressurized for a period of time of about 20 to 30 minutes, together with ultrasound;
• (3) rinsing the implant a first time, wherein the dental implant is immersed in deionized water;
• (4) drying the implant, wherein the implant is placed in a dryer at a temperature ranging from about 70° to about 80° C., for a period of time of about 30 to 40 minutes;
• (5) blasting the implant, wherein the implant is placed in a blasting chamber using abrasive aluminum oxide (Al2O3) with an average particle size of 90 microns;
• (6) cleaning the external screw a second time, wherein the implant is immersed in a washing solution with D'Limonemo, in average heated concentration of 3:50, pressurized for a period of time of about 20 to 30 minutes, together with ultrasound;
• (7) rinsing the implant a second time, wherein the dental implant is immersed in deionized water;
• (8) drying the implant a second time, wherein the implant is placed in a dryer at a temperature ranging from about 70° to about 80° C., for a period of time of about 30 to 40 minutes;
• (9) etching the implant a first time, wherein the implant is immersed in an etching solution consisting of from 10% to 30% in volume of nitric acid 70%, and from 1% to 3% in volume of hydrofluoric acid 60% at 50° C.;
• for a maximum time of 2 minutes;
• (10) neutralizing the etched implant, wherein the implant is immersed in a container with a neutralizing solution of sodium bicarbonate, having a pH of between 6 and 8, and further immersed in a solution of sodium bicarbonate, having a pH of between 7 and 8;
• (11) rinsing the implant a third time, wherein the dental implant is immersed in deionized water.
• (12) bathing the implant in isopropyl alcohol and deionized water, wherein the implant is immersed in a solution of isopropyl alcohol 99.5%, for a period of time of from 20 to 30 minutes;
• (13) bathing the implant in deionized water, wherein the dental implant is immersed in deionized water;
• (14) etching the implant a second time, wherein the implant is immersed in a passivation solution consisting of deionized water and nitric acid at a concentration of 30% in weight, for a period of time of about 40 minutes;
• (15) neutralizing the second time etched implant, wherein the implant is immersed in a solution of sodium bicarbonate, having a pH of between 7 and 8;
• (16) rinsing the second time etched implant, wherein the dental implant is immersed in deionized water;
• (17) bathing the second time etched implant in deionized water, wherein the dental implant is immersed in deionized water;
• (18) drying the second time etched implant, wherein the implant is placed in a dryer at a temperature ranging from about 70° to about 80° C., for a period of time of about 30 to 40 minutes.
