“…Titanium and its medical-grade alloys, in particular, Ti6Al4V alloy, are the materials of choice for realizing a wide range of dental implant and implant trans-mucosal components [ 11 ]. This material has excellent biocompatibility and resistance to corrosion, also providing high strength resistance and overall good mechanical properties [ 12 , 13 , 14 ].…”

This study aimed to grow a fungal-bacterial mixed biofilm on medical-grade titanium and assess the ability of the biosurfactant R89 (R89BS) coating to inhibit biofilm formation. Coated titanium discs (TDs) were obtained by physical absorption of R89BS. Candida albicans-Staphylococcus aureus biofilm on TDs was grown in Yeast Nitrogen Base, supplemented with dextrose and fetal bovine serum, renewing growth medium every 24 h and incubating at 37 °C under agitation. The anti-biofilm activity was evaluated by quantifying total biomass, microbial metabolic activity and microbial viability at 24, 48, and 72 h on coated and uncoated TDs. Scanning electron microscopy was used to evaluate biofilm architecture. R89BS cytotoxicity on human primary osteoblasts was assayed on solutions at concentrations from 0 to 200 μg/mL and using eluates from coated TDs. Mixed biofilm was significantly inhibited by R89BS coating, with similar effects on biofilm biomass, cell metabolic activity and cell viability. A biofilm inhibition >90% was observed at 24 h. A lower but significant inhibition was still present at 48 h of incubation. Viability tests on primary osteoblasts showed no cytotoxicity of coated TDs. R89BS coating was effective in reducing C. albicans-S. aureus mixed biofilm on titanium surfaces and is a promising strategy to prevent dental implants microbial colonization.

“…In torsional tests, rod loosening occurred at presumably very low torque values; therefore, a treatment of the threaded rod before the application of an adhesive was considered, as Najeeb et al [ 58 ] demonstrated in their study. The resistance to torque force observed after the treatment and with resin cement, zinc oxyphosphate cement, or butyl-cyanoacrylate was around two-fold that obtained if the force was applied on the PEEK part.…”

Exo-endoprosthesis is a limb salvage procedure poorly described for animals, as only expensive metal devices have been used so far. Currently, additive manufacturing (AM) can make this type of implant affordable by exploring a wide new range of materials. However, safety factors should be considered and could be related to kinetic and kinematic studies of canine natural gaits. The suitability of a novel inner part of an exo-endoprosthesis manufactured by fuse deposition modeling (FDM) was assessed for long canine bones with an elliptical medullary canal. Polyether ether ketone (PEEK) was the material used as an alternative to metal for veterinary traumatology. Poisson’s ratio of 3D-printed PEEK material and ex vivo mechanical tests of the customized endoprosthesis were performed for the evaluation. The customized endoprostheses had promising outcomes for the radii of 20 kg dogs. Quasistatic mechanical tests of bone-inserted endoprostheses—pure compression tests—reached a maximum force of 1045.0 ± 78.0 N. In fatigue tests, the samples reached 500,000 cycles without failure or detriment to their quasistatic results. These outcomes surpass the natural weight-bearing of dogs, even during a galloping pace. Furthermore, torque tests with different adhesives were performed to obtain reference data for future assessments comparing with natural dog movements.

“…27,28 Furthermore, in implant dentistry, researchers are also developing newer surface-treated and coated implants to improve the osseointegration by interactions between proteins, cells and tissues, and bone grafts to deal with bone defects and peri-implantitis. [29][30][31] This information should also be given to the patients. The results of this study might act as a baseline data to formulate the patient's education and motivation strategies to pave way for its ready acceptability in the society.…”

Objective To assess the patient’s level of awareness of dental implants as an option to replace missing teeth and willingness to accept dental implant is lacking in a small city (Chitwan) Nepal. Materials and methods A cross-sectional survey was conducted on patients attending the prosthodontic, oral medicine and radiology clinics of Chitwan Medical College, Chitwan, Nepal. A self-administered questionnaire was used after pretesting through a pilot survey. The data analysis was done using SPSS version 20 (IBM Company, Chicago, USA). Statistical Analysis Various parameters were compared using Two-Sample Independent T-Test. The level of significant was set at p value = 0.05. Results A total of 84 subjects responded to the study. Only 47.6% of the participants have knowledge on dental implants. Majority of the participants (72%) considered the costs to be affordable and equal number of the participants replied that they were ready for treatment with dental implant. Majority of the participants received information from their dentists (53.1%) and from the friends and acquaintances (31.3%). The patients in Chitwan have moderate awareness of dental implants. Majority of the participants are aware and willing to consider dental plant treatments. Conclusions The patients in Chitwan have moderate awareness of dental implants. Majority of the participants are aware and willing to consider dental plant treatments. Proper information on dental implants should be provided to the patients so that they can accept the dental implant treatment.
