Comparison of Er:YAG laser and piezoelectric osteotomy: An animal study in sheep

Abstract

Er:YAG laser osteotomy can successfully be used in long bones with a depth of up to 22 mm, thus challenging the dogma of adverse effects of laser osteotomy due to thermal or other damages.

Morphological Characteristics of Osteotomies Using Different Piezosurgical Devices. A Scanning Electron Microscopic Evaluation

“…10,11,14,15,18,22,23,[25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] In an in vitro study by Müller 9 comparing osteotomies created in various ways, showed that Piezosurgical (Mectron) osteotomies were morphologically similar to those created with conventional drills or microsaws. Romeo et al 36,45 in another in vitro study, compared the Er:YAG laser, a Piezoelectric device (Mectron), a high-speed handpiece using Lindemann burs and round diamonds, and a low-speed handpiece using round stainless steel burs.…”

“…1,10,[12][13][14][15][16][17][18][19] Hollstein et al 20 examined the differences in performance of 5 types of Piezosurgical devices, specifically the duration of osteotomies, surface roughness, osteoblast vitality, and osteotomy site micromorphology. However, 3 of those 5 devices were manufactured by Mectron (the Piezosurgery 3, Piezotom 2, and Piezosurgery Medical).…”

“…[8][9][10] However, only 1 study has compared different Piezosurgical units with conventional methods, 11 and no studies have compared the morphological characteristics of the osteotomy obtained by using different Piezosurgical units under the same experimental conditions. This study was therefore undertaken to examine the different morphological characteristics of osteotomies created using 6 different Piezosurgical devices, all under the same experimental conditions.…”

Healing of osteotomy sites applying either piezosurgery or two conventional saw blades: a pilot study in rabbits

“…Owing to their great manoeuverability in the recent past, lasers and high-pressure water jets have been evaluated. However, even though results especially for certain laser systems were promising [24], in daily routine oscillating and ultrasound based systems are still preferred by surgeons. Osteotomy speed and depth control using saw blades is still unrivalled.…”

Biomedical Optics and Lasers

“…However, low heat production risk of erbium makes it superior regarding thermal necrosis of the living tissues like dental pulp [83] and bone marrow [84].…”
