ABSTRACT
Objective:
An evaluation and comparison is made of the thermal increment at different implant surfaces during irradiation with CO2 and ErCrYSGG lasers.Studydesign:
Five threaded and impacted implants with four types of surfaces were inserted in an adult pig ribtwo implants with a hydroxyapatite surface (HA)(impacted and threaded, respectively), a machined titanium surface implant (TI mach), a titanium plasma spray surface implant (TPS), and a sandblasted, acid-etched surface implant (SBAE). A 0.5-mm diameter bone defect was made in the implant apical zone, and a type-K thermocouple(Termopar)® was placed in contact with the implant. The implants were irradiated in the coronal zone of each implant with a CO2 (4 W continuous mode) and an ErCrYSGG laser (1.5 W, pulsed mode) first without and then with refrigeration. The temperature variations at the implant apical surface were recorded.Results:
An apical temperature increase was recorded in all cases during CO2 and ErCrYSGG laser irradiation without refrigeration. However, when the ErCrYSGG was used with a water spray, a decrease in temperature was observed in all implants. The acid-etched and sandblasted surfaces were those most affected by the thermal changes.Conclusions:
The ErCrYSGG laser with a water spray applied to the sealing cap or coronal zone of the implants does not generate thermal increments in the apical surface capable of adversely affecting osseo integration and the integrity of the peri-implant bone tissue (AU)RESUMEN
