Infrared Laser Light Reduces Loading Time of Dental Implants: A Raman Spectroscopic Study

Abstract

It is concluded that LLLT does improve bone healing, and this can be safely assessed by Raman spectroscopy.

Stability of dental implants after irradiation with an 830-nm low-level laser: a double-blind randomized clinical study

“…The GaAlAs laser with an 830-nm wavelength was selected on the basis of successful results obtained on fibroblasts and also on osteoblasts, both in vitro and in vivo by different authors [15][16][17][33][34][35][36][37][38][39][40][41][42][43][44][45]. The infrared lasers are known to have a greater depth of tissue penetration in comparison to red or blue light [46], thus, the osteoblasts cells could better absorb the laser energy because of the low water absorption at that wavelength [33,36,45].…”

“…Little data exist concerning these effects on the osseointegration process of implants [14][15][16][17].…”

Effect of Three Different Protocols of Low-Level Laser Therapy on Thyroid Hormone Production After Dental Implant Placement in an Experimental Rabbit Model

“…These procedures would not be possible in rats or mice. 9,10,13,40 In accordance with the most recent literature, LLLT was delivered by an infrared laser [7][8][9][10][11][12][13][14][15][26][27][28]35,38 of 830 nm wavelength 7,10,[12][13][14][15] and 50 mW output power in two sites near the mandibular implant, in seven sessions 7,11,12,15 every 48 h, using three different doses. The use of a sham surgery and sham LLLT control group (C-I), as well as a baseline surgery but sham LLLT group (C-II), enabled us to isolate both the influence of baseline surgery and the systemic effects of LLLT.…”

“…Previous studies have evaluated the irradiation of extraction sockets, 3 modulation of skin wound healing, [4][5][6] regeneration of nervous tissue, 5 enhancement of peri-implant tissue repair after implant placement, 2,[7][8][9][10][11][12][13][14][15][16] and modulation of postoperative pain. 2,7,[17][18][19][20][21][22][23][24] Other in vivo and in vitro studies have reported the positive effects of LLLT on the repair process in animal models and tissue cultures.…”

“…2,7,[17][18][19][20][21][22][23][24] Other in vivo and in vitro studies have reported the positive effects of LLLT on the repair process in animal models and tissue cultures. 4,22,25 However, there are large variations in laser doses, [7][8][9][10][11][12][13][14][15]26 even though dose is considered an important parameter in laser therapy, 27 especially when some specific biomodulatory effects are expected.…”
