“…Fluoride modification on the implant surface leads to morphologic and physiochemical phenomena that are of significance for osteoblastic differentiation and interfacial bone response (Cooper et al, ; Ellingsen, ; Ellingsen, Johansson, Wennerberg, & Holmén, ). Unlike those fluorine elements embedded into fluoride‐modified titanium implants in the form of stable compounds, the free serum fluorine around the titanium implants under fluoride exposure affects the surrounding bone metabolism and reduces the corrosion resistance of titanium (Anwar, Kheiralla, & Tammam, ). Joska and Fojt () found that the excessive free fluoride could exist in the whole depth of oxide layer on titanium surface, with an increased thickness but less protective than that formed in fluoride‐free solutions.…”

Objective: This study aims to investigate the influence of fluoride exposure on implant osseointegration.Methods: A total of 24 male New Zealand white rabbits were randomly divided into the control group and the fluoride exposure group. Rabbits in the control group were fed with tap water, while those in the fluoride exposure group were given 200 mg/L sodium fluoride solution. After 2-month feeding, implants were inserted into the extraction socket immediately after extraction of rabbit mandibular anterior teeth.Four rabbits in each group were sacrificed to collect the implants samples at 1, 2, and 3 months post-implantation, respectively. Radiographic and histomorphometry examinations were performed to evaluate the condition of implant osseointegration.Results: Bone volume around the implants increased in a time-dependent manner in both groups. Micro-CT images illustrated that the bone mineral density (BMD) in the fluoride exposure group was significantly lower than that in the control group after implantation for 2 and 3 months. The bone-implant contact ratio (BIC) in the fluoride exposure group was much lower than that of the control group at 3 months post-implantation according to histomorphometry examination. Conclusions:In rabbit animal model, high fluoride exposure affected the quality of bone surrounding the implant and significantly reduced bone integration of the implant, especially in the late stage of osseointegration.

“…Diverse electrochemical methods were used to observe the effect of fluoride ion concentration on the corrosion behavior of Ti and Ti6-Al-4V implant alloys, in AS when coupled with either metal/ceramic or all ceramic superstructures. This lead to the conclusions that while fluoride concentration increases corrosion resistance of Ti and its Ti6-A1-4V alloy decreases [12]. Ti-Co alloy [10] and Ti-Cu alloy [24] gave parallel consequences.…”

“…To recognize these effects, numerous investigations were undertaken. Corrosion resistance of metals and alloys in AS, in the presence of fluoride has been investigated [1,10,11,12,14,19,24] The presence of fluoride ions (added as NaF) drastically affects the corrosion behavior of Ti metal, Ti-6Al-7Nb, and Ti-6Al-4V alloys and constituent metals in AS as confirmed by electrochemical methods [1]. All the titanium alloys in fluoridated acidified saliva show an active behavior due to the presence of major concentrations of HF and HF2− species that dissolve the spontaneous air-formed oxide film giving rise to surface activation [13].…”

“…It is further enhanced by the fluoride ions in toothpaste and in the products used as mouthwash as it plays the role of an essential factor accelerating corrosion [5][6][7][8][9]. Corrosion resistance of biomaterials made up of various metals and alloys has been investigated in artificial saliva (AS); various metals and alloys such as Ti-Co alloy [10], Ti30Ta alloy [11], Ti metal, Ti6-Al-7Nb, and Ti-6Al-4V alloy [1,12], Ti-6Al-7Nb alloy [13], Co-Cr alloy [14][15][16][17][18], CP-Ti and Ni-Cr-Ti alloy [19], Co-Cr-Mo alloy [20,21], Ni-Cr alloy [18,22,23], Ti-Cu [24], Ti-20Zr alloy [25], Ti12Mo and Ti60Ta [26], Ni-Ti shape memory alloy and stainless steel wire [27], Ti-Mo [28], mild steel coated with zinc [29], NaOCl [30], and 60NiTi [31].

Dental erosion is the chemical dissolution of the tooth structure. Factors like eating disorders and gastrointestinal diseases are recognized as intrinsic factors for dental erosion. To regulate the growth of teeth, people are implanted with orthodontic wires made of different materials. These are exposed to the influence of oral environment, food intake, toothpastes, and mouthwashes. During this process, the materials may undergo corrosion. Hence, various researchers have made a study on the influence of artificial saliva (AS) on the corrosion behavior of these alloys. The excellent corrosion resistance to the oral environment of dental alloys is important for biocompatibility as well as for orthodontic employment permanence. Various types of metal alloys are being used for the orthodontic treatment, which undergo chemical or electrochemical reaction with the oral environment. The oral environment is highly belligerent under several situations and leads to corrosion. This article reviews the effects of fluoride concentration, the pH value and protein content in AS and the composition of the metal alloys on the corrosion resistance of orthodontic appliances using electrochemical methods and surface characterization techniques such as scanning electron microscopy inductively coupled plasma-optical emission spectroscopy (ICP-OES) and X-ray photoelectron microscopy.

“…Titania (TiO 2 ) has been previously shown to have good biocompatibility with human corneal stroma fibroblasts and epithelial cells 1415 In addition TiO 2 has a protective layer of oxide film that is stable, bioinert and provides the material with resistance to corrosion in tissue fluids for example, artificial saliva 1617 These properties make TiO 2 a potential substitute to HA as a synthetic OOKP skirt material.…”

AimKeratoprosthesis (KPro) devices are prone to long-term corrosion and microbiological assault. The authors aimed to compare the inflammatory response and material dissolution properties of two candidate KPro skirt materials, hydroxyapatite (HA) and titania (TiO2) in a simulated in vitro cornea inflammation environment.MethodsLipopolysaccharide-stimulated cytokine secretions were evaluated with human corneal fibroblasts on both HA and TiO2. Material specimens were subjected to electrochemical and long-term incubation test with artificial tear fluid (ATF) of various acidities. Topography and surface roughness of material discs were analysed by scanning electron microscopy and atomic force microscopy.ResultsThere were less cytokines secreted from human corneal fibroblasts seeded on TiO2 substrates as compared with HA. TiO2 was more resistant to the corrosion effect caused by acidic ATF in contrast to HA. Moreover, the elemental composition of TiO2 was more stable than HA after long-term incubation with ATF.ConclusionsTiO2 is more resistant to inflammatory degradation and has a higher corrosion resistance as compared with HA, and in this regard may be a suitable material to replace HA as an osteo-odonto-keratoprosthesis skirt. This would reduce resorption rates for KPro surgery.
