“…In 2008, Kim et al10 reported increased corrosion resistance and strength with less mechanical failures of miniscrews uniformly coated with ZrN and TiN compared with untreated miniscrews. An improvement in miniscrew strength can enhance the initial stability with less deformation of threads during insertion.…”

“…For example, Habig9 indicated that TiN coating of various dental metals by using this method improves wear and discoloration resistance as well as enhances mechanical characteristics. Further, Kim et al10 reported that TiN-coated miniscrews have decreased corrosion current density and increased pitting resistance compared with noncoated miniscrews. These findings indicate that TiN coating by plasma ion implantation can improve the corrosion resistance and hardness of orthodontic miniscrews.…”

ObjectiveTo gain basic information regarding the biologic stability of plasma ion-implanted miniscrews and their potential clinical applications.MethodsSixteen plasma ion-implanted and 16 sandblasted and acid-etched (SLA) miniscrews were bilaterally inserted in the mandibles of 4 beagles (2 miniscrews of each type per quadrant). Then, 250 - 300 gm of force from Ni-Ti coil springs was applied for 2 different periods: 12 weeks on one side and 3 weeks contralaterally. Thereafter, the animals were sacrificed and mandibular specimens including the miniscrews were collected. The insertion torque and mobility were compared between the groups. The bone-implant contact and bone volume ratio were calculated within 800 µm of the miniscrews and compared between the loading periods. The number of osteoblasts was also quantified. The measurements were expressed as percentages and analyzed by independent t-tests (p < 0.05).ResultsNo significant differences in any of the analyzed parameters were noted between the groups.ConclusionsThe preliminary findings indicate that plasma ion-implanted miniscrews have similar biologic characteristics to SLA miniscrews in terms of insertion torque, mobility, bone-implant contact rate, and bone volume rate.

“…One would think that this intimate bone-implant relationship comes at a cost of tissue damage to the surrounding bone while retrieval of miniscrews Current Concepts in Dental Implantology -From Science to Clinical Research at the end of the treatment period. Studies have shown that despite SLA treated miniscrews having greater BSC and RT values on removal, there was no reported bone fracture or tissue destruction during unscrewing [30,46]. Kim et al recommended a non-loading period of fewer than 6 months before removal for optimal bone health and post-operative healing [37].…”

“…In this technique, the surface of orthodontic miniscrews is coated with a thin film of titanium nitride (TiN) and/or zirconium nitride (ZrN) which acts as a protective layer (Figure 6). Kim et al studied the mechanical and electrochemical changes on the surface of plasma ion implanted miniscrews [46]. Field emission SEM (FE-SEM) and EDS analysis showed that when compared to non-coated miniscrews, the TiN and ZrN coated miniscrews had a smoother surface owing to a decrease in the number of machined defects.…”

Orthodontic miniscrews have had a considerable impact on modern orthodontic treatment, not only by providing a new source of anchors for anchorage-demanding cases, but also for force management and control. Whilst miniscrews need to be mechanically stable during treatment to provide sufficient anchorage and predictable force control, as temporary anchorage devices they need also be easy to remove after orthodontic treatment. These requirements differentiate orthodontic miniscrews from dental implants - which once placed, are not to be removed - and dictate the approach as to how their clinical performance can be optimized. Over the past decade, various titanium surface modifications and improvements in implant surface topography have shown to enhance osseointegration of endosseous dental implants. Some of these techniques have helped provide a similar enhancement of the biomechanical potential of orthodontic miniscrews as well. In this perspective, we present a brief discussion on all such reported techniques followed by a detailed account of the most recently proposed ultraviolet photofunctionalization technique - a novel chair-side surface modification method.

OBJECTIVE: The need to overcome the failure of orthodontic micro-implants which might reach to 30% has led to the development of different methods, one of which is nanoparticle deposition. AIM OF STUDY: To evaluate the anti-microbial efficiency of TiO2 and ZnO nanoparticles (NP) when used as a coating for orthodontic micro-implants. METHODS: Thirty titanium alloy micro-implants were used in the presented study. They were divided into three groups according to the coating method and the coating materials used: the control group without surface coating; the titanium dioxide (TiO2)-coated group, in which direct current (DC) spattering was used to coat the micro-implants with a TiO2 layer; and the TiO2 and zinc oxide (TiO2ZnO)-coated group, in which the micro-implants were coated with a TiO2 layer via direct current (DC) spattering and a zinc oxide (ZnO) layer via laser vacuum. The micro-implant surfaces were characterized using scanning electron microscopy (SEM) and an energy-dispersive spectrometer (EDS). The antibacterial susceptibility was assessed using gram-positive and gram-negative bacteria. RESULTS: SEM and EDS tests confirmed the coating of the micro-implants in the TiO2- and TiO2ZnO-coated groups. The micro-implants in the TiO2- and TiO2ZnO-coated groups demonstrated higher antibacterial ability than the control group. CONCLUSION: This study demonstrated the significance of improving the surface of orthodontic micro-implants by coating them with TiO2 and ZnO nanoparticles to improve osseointegration and prevent biofilm formation.
