The Use of Laser Diodes Superpulses in Implantology

Abstract

Diode laser is a laser, usually between 810 and 980 nm wavelength, able to work on hard and soft tissues, as periodontal tissues and bone. The use of Diode laser is recommended during oral surgery or periodontal therapy, when it is necessary to erase any periodontal bacteria evolved in periodontal disease, in combination with hydrogen peroxide (photodynamic therapy), and also, by its biostimulating effects, to improve the healing of the regenerative procedures, as sinus lift, bone crestal expansion or to assist implant surgery. This article shows two cases report in which diode lasers are evolved. Diode lasers in association with Hydrogen Peroxide on utilizing the decontaminant effects oh Photodynamic Therapy, and to prepare the area defects for a regenerative surgery.

A Preliminary In Vitro Study on the Efficacy of High-Power Photodynamic Therapy (HLLT): Comparison between Pulsed Diode Lasers and Superpulsed Diode Lasers and Impact of Hydrogen Peroxide with Controlled Stabilization

“…PDT performed with pulsed or continuous LLLT seems to show clear efficacy limits due to the following reasons:The very low power (below 1 Watt) cannot ensure a proper bactericidal efficacy on microorganisms that are responsible for periodontal diseases.The laser penetration capacity is limited, due to the energy absorbed in tissues imbibed with dyed photosensitizer [18, 20, 21]. …”

“…PDT performed with pulsed or continuous LLLT seems to show clear efficacy limits due to the following reasons: The very low power (below 1 Watt) cannot ensure a proper bactericidal efficacy on microorganisms that are responsible for periodontal diseases. The laser penetration capacity is limited, due to the energy absorbed in tissues imbibed with dyed photosensitizer [ 18 , 20 , 21 ]. Nonetheless, LLLT shows a good biostimulation effect: the purpose of laser-assisted biostimulation is to stimulate the activity of the cells designated to the regeneration of tissues [ 18 , 20 , 21 ] lost because of the aggression of oral pathogens.…”

“…The test is performed with current methods [ 18 ] on cultures of typical strains causing infections in the oral cavity.…”

“…The nonsurgical periodontal therapy combining a 980 nm laser with hydrogen peroxide is gaining more and more consensus in clinical dental practice as shown in Rey protocol [ 18 , 19 ].…”

“…The benefits of hydrogen peroxide as opposed to classic photodynamic therapy (PDT) performed with photoactivating agents with absorption within the visible band consist in a higher bioavailability and deeper penetration in the biofilms as well as in the scarce interference in respect to the irradiation performed ( Figure 1 ) [ 18 ].…”
