This paper describes a comparative study of residual heat deposition of Er:YAG and Er,Cr:YSGG lasers during ablation of hard dental tissues. Residual heat deposition was obtained from measured irradiated hard tissue temperature decay characteristics immediately following Erbium laser pulses. The measured residual heat was larger in enamel than in dentine for both Er:YAG and Er,Cr:YSGG […]
Dental Laser Drilling: State of the Art with the Latest Generation of variable Square Pulse Erbium Dental laser Systems
The most recent technological breakthroughts incorporated in the latest generation of Variable Square Pulse (VSP) Er:YAGdental lasers involve two additional features: SSP (Super Short Pulse) mode for extremely fine and minimal invasive laser ablation; and MAX mode for maximum optical drilling speeds. The objective of this study was to make a comparision between the two […]
Novel Fractional Treatments with VSP Erbium YAG Aesthetic Lasers
Le indicazioni per l’utilizzo dell’Er:YAG laser sono in continua espansione. In questo lavoro viene presentato l’ultima tecnologia Pixel Screen Technology (PST), tecnica frazionata minimamente invasiva per l’utilizzo di un Er:YAG laser nel ringiovanimento della pelle. La tecnica frazionata è basata sul concetto di produrre una fila di onde microscopiche sulla superficie della pelle che viene […]
Laser Profilometry for the Characterization of Craters Produced in Hard Dental Tissues by Er:YAG and Er,Cr:YSGG Lasers
A new, highly accurate and repeatable methodology based on the principle of optical triangulation to measure ablation rates in hard dental tissues is introduced. Using this methodology, a comparison is made between the two leading laser wavelengths for hard tissue procedures in dentistry, Er:YAG (Fidelis Plus III, Fotona) and Er,Cr:YSGG (Waterlase MD, Biolase). In-vitro measurements […]
Dental laser drilling: Achieving optimum ablation with the latest generation Fidelis laser systems
This paper provides an overview of the scientific principles of hard dental tissue laser procedures and discusses the influence of laser wavelength, pulse duration and pulse energy. Erbium lasers have been found to be a safe and efficient technological solution for the manipulation of hard dental tissues. The ability to precisely control laser pulse duration […]
New Options and Treatment Strategies with the VSP Erbium YAG Aesthetics Lasers
Er:YAG laser resurfacing has been widely recognized as an effective and predictable method to reverse the signs of photo-damage. Whereas other ablative light-technologies have not developed much further, therefore limiting their versatility and applicability, new developments and innovations to Er:YAG lasers have given practitioners a wide variety of new treatment options and strategies. In order […]
State of the Art in Lasers for Dentistry
Lasers have been used in dentistry since 1964. The idea was to be able to treat both soft tissues and hard tissues, including bone, without direct contact, vibrations and pain. Since the early 90’s lasers have been applied in a wide variety of dental application areas. In this paper Prof. dr. Norbert Gutknecht, President of […]
