The Esthetic Crown Lengthening by Er;Cr:YSGG laser: A Case Series

Abstract

Introduction: Laser technology as a new modality in dentistry has gained special attention. Among different types of lasers, erbium lasers have gained special attention for management of oral soft and hard tissue simultaneously. This study presents series of cases of crown lengthening (CL) and restorations accomplished by erbium, chromium: yttrium-scandium-gallium-garnet (Er,Cr:YSGG). Case Reports: Seven patients were selected for this study. After complete oral examination and diagnosis, the treatment plan of each patient was designed. All cases needed esthetic CL. In some cases, frenum revision and class V cavity preparation was done by Er;Cr:YSGG laser. All patients treated with Er;Cr:YSGG laser producing a wavelength of 2780 nm (Biolase, Irvine, California, USA); Tip T4, 400 µm Diameter for soft tissue management and Tip G6, 6 mm long, 600 µm diameter for hard tissue management. Results: All patients reflected acceptable results based on clinical evaluation and patients’ declaration of post-surgical status. Conclusion: Using Er;Cr:YSGG laser in class v cavity preparation and flapless CL seemed to be effective and beneficial.

Minimally invasive (flapless) crown lengthening by erbium:YAG laser in aesthetic zone

“…Several medical devices have been proposed to make CL less invasive, including piezosurgery 4 , 8 . Several lasers such as diode, neodymium-doped yttrium aluminum garnet (Nd:YAG), potassium titanyl phosphate (KTP), CO 2 , Erbium, chromium-doped yttrium, scandium, gallium and garnet (Er,Cr:YSGG) and erbium:YAG are widely used for CL 1 , 2 , 6 , 9 . However, the main difference between these is their capability to work exclusively on soft or hard or both tissues 3 , 9 , 10 .…”

“…medically compromised patients or in therapy with anticoagulant drugs). Many alternatives techniques for CL have been reported in literature but it is generally accepted that the least invasive are the laser-assisted techniques 5 , 6 . Of these, the erbium:YAG laser has the advantage to work on both hard (bone) and soft tissues (gingiva) 7 .…”

Prevalence of different methods of crown lengthening and its preference among dental specialties

“…Laser is a newly developed technology which is used in multiple ields of dentistry such as dental bleaching, a crown lengthening (CL), restoratives, endodontic and implant surgeries (Lizarelli et al, 2008;Stübinger, 2010;Ruschel et al, 2016) Lasers have multiple advantages over rotary techniques such as; increased safety, decreased pain, increased comfort, decrease noise and vibrations (Stübinger, 2010;Parhami et al, 2014;Fekrazad et al, 2018). The use of laser helps in the effective management of soft tissue during restorative procedures (Ranganathan et al, 2017).…”
