Effect of the Magnetic Field Generated by a New NeFeB Cover Screw on Bone Healing around Endosseous Implants: A Case Series Report from Dental Practice

Abstract

This study aimed to investigate the effect of static magnetic field (SMF) generated by innovative cover screws made of NeFeB on early bone healing around dental implants. The study was carried out on humans in a private dental practice. Eight 3i implants (Biomet, Palm Beach, FL, USA) were placed in the posterior mandible at 3.6 and 3.7. The control implants were closed with a conventional screw (G1), while the test implants were closed with a Supercharged® screw (G2). Both groups were compared for stability at 0, 7, 14, 21, 50, and 90 days using a resonant frequency analyzer with Ostell Mentor (Osstell AB, Gothenburg, Sweden). After 50 days, the Supercharged® cover screw was removed. A significant increase in implant stability quotient (ISQ), corresponding to a lower degree of bone resorption, was observed in G2 throughout the follow-up period (p < 0.05), while an initial ISQ decrease was observed until day 21 in G1. In conclusion, the effect of SMF seems to be in the early stages of osseointegration and increases the stability of dental implants.

Blood Clotting Dissolution in the Presence of a Magnetic Field and Preliminary Study with MG63 Osteoblast-like Cells—Further Developments for Guided Bone Regeneration?

“…The growing interest in the application of magnetic fields in bone metabolism in order to facilitate its maturation has been well highlighted in various scientific papers. In particular, in dentistry to favour implant osteointegration and slow down crestal resorption around the implant itself [ 29 , 30 , 31 ], as well as to promote the maturation of multipotent cells in order to cure periodontal disease in the future [ 32 ]. Moreover, the application of magnetic fields is being applied in the study of bone-tissue growth in order to evaluate the cell–cell and cell–extracellular matrix interaction [ 20 , 21 , 22 , 23 ].…”

“…The use of magnetic fields has been applied in orthodontics (movement of the teeth) and prosthodontics (maxillofacial prosthesis and in overdentures) [ 28 ] and in implantology with the purpose of improving osteointegration [ 29 , 30 , 31 ]. Moreover, the possible application of the magnetic field for the treatment of periodontal disease is currently being studied [ 32 ].…”

Sem and in Vivo Study of Adhesion Characteristics of Titanium and Polytetrafluoroethylene Surfaces Healing Screws

“…the Once healing has occurred, we move on to the second phase characterized, however, by the surgical exposure of the implant to proceed with the incorporation of the abutments in order to optimize prosthetic rehabilitation. [18][19][20][21] . In another studies Author show that it could be right the use of photobiomodulation for improve the bone healing.…”

In Vitro Study of the Proliferation of MG63 Cells Cultured on Five Different Titanium Surfaces

“…These types of results have led some researchers, in particular Simion et al [32,33], to go back to machined implants, without treatment. In the literature, there have been some interesting works on the improvement of the osteoblastic response obtained without altering the bone surface, but only by using particular cap screws for implants equipped with static magnetic fields [34][35][36][37]. The static magnetic fields according to these studies have been demonstrated, both in vitro and in vivo, to increase osteoblast differentiation and increase bone matrix deposition.…”
