The Effect of a Constant Electrical Field on Osseointegration after Immediate Implantation in Dog Mandibles: A Preliminary Study

Abstract

Minimal direct electrical current, which can produce an electrical field around the implant, can increase the amount of bone formation and decrease the time of osseointegration.

A mathematical framework for predicting thermal damage during bone electrostimulation

“…Our approach allows analysing the influence of both EF and heating during the migration of osteoprogenitor cells into the wound site and the subsequent synthesis of a new bone matrix. The numerical results are in agreement with experimental observations on both bone formation (Shayesteh et al, 2007) and tissue damage by heat accumulation (Li et al, 1999), and provide additional insights into the incidence of the thermal effect during ES. This paper is organized as follows.…”

Electroterapia para la Regeneración Ósea de Implantes Dentales

“…En términos de contacto óseo con implante, Shayesteh et al (2007), presentaron un estudio en canes donde observaron que la estimulación eléctrica constante aumenta la cantidad de hueso en contacto con la superficie del implante y también podría disminuir el tiempo de oseointegración; sin embargo, la aplicación clínica es controversial en esta investigación.…”

Effect of Static Magnetic Fields on the Osseointegration of Immediately Placed Implants

“…These findings have brought electromagnetic fields into attention to shorten the healing period after implant installation. 17,18,29 Matsumoto et al 29 indicated that the application of PEMF may be useful for enhancing bone formation around rough-surfaced dental implants. In addition, Shayesteh et al 17 demonstrated that the stimulation of constant electromagnetic field increased the amount of bone formation and shortened osseointegration period in dental implants placed immediately after tooth extraction in an animal model.…”

“…Although electromagnetic fields have demonstrated promising results in shortening the osseointegration period in both in vitro and in vivo studies, 17,18,27,29 there is still a lack of clinical studies on the effects of electromagnetic fields on implant osseointegration. The aim of this randomized controlled clinical study was, therefore, to evaluate the effects of SMFs generated by magnetic abutments on implants immediately placed in fresh extraction sockets.…”

“…These attempts have focused on immediate 15 and early loading 9 protocols, changes in implant design, 16 and proposing innovations that could improve osseointegration, such as electrical stimulations and electromagnetic fields. 17,18 Electromagnetic field treatment is a useful therapeutic modality that has shown to be effective in a variety of medical conditions, including nonunion bone fractures, migraines, skin ulcers, and degenerative nerves. 19 A magnetic field is a region surrounding Purpose: The aim of this study was to evaluate the effects of static magnetic fields (SMFs) on the implants immediately placed in fresh extraction sockets.…”
