“…Furthermore, various polymeric films with antibiotics such as tetracycline hydrochloride polylactic acid, poly(e-caprolactone), and polymer/ tetracycline-containing solutions, reduce peri-implantitis development and associated pathogens. 46 Local antibiotics, such as MNO, doxycycline, or CHX, are effectively combined with mechanical treatments for peri-implantitis, especially for incipient to moderate lesions. MNO and doxycycline have shown better results compared with CHX.…”

Despite the success rates of dental implants, peri-implantitis presents as the most common complication in implant dentistry. This review discusses various factors associated with peri-implantitis and various available treatments, highlighting their advantages and disadvantages. Relevant articles on peri-implantitis published in English were reviewed from August 2010 to April 2020 in MEDLINE/PubMed, Scopus, and ScienceDirect. The identified risk indicators of peri-implant diseases are plaque, smoking, history of periodontitis, surface roughness, residual cement, emergence angle >30 degrees, radiation therapy, keratinized tissue width, and function time of the implant, sex, and diabetes. Peri-implantitis treatments can be divided into nonsurgical (mechanical, antiseptic, and antibiotics), surface decontamination (chemical and laser), and surgical (air powder abrasive, resective, and regenerative). However, mechanical debridement alone may fail to eliminate the causative bacteria, and this treatment should be combined with other treatments (antiseptics and surgical treatment). Surface decontamination using chemical agents may be used as an adjuvant treatment; however, the definitive clinical benefit is yet not proven. Laser treatment may result in a short-term decrease in periodontal pocket depth, while air powder abrasive is effective in cleaning a previously contaminated implant surface. Surgical elimination of a pocket, bone recontouring and plaque control are also effective for treating peri-implantitis. The current evidence indicates that regenerative approaches to treat peri-implant defects are unpredictable.

“…A wide range of polymers are commonly used for various applications in clinical dentistry [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Amongst these, poly methyl methacrylate (PMMA) is a polymer that is most commonly used in dental laboratories (to make orthodontic retainers and dentures and for repair), dental clinics (for relining dentures and temporary crowns), and industry (such as fabrication of artificial teeth) [ 7 , 9 , 10 ].…”

Prosthodontic Applications of Polymethyl Methacrylate (PMMA): An Update

2020

View full text Add to dashboard Cite

A wide range of polymers are commonly used for various applications in prosthodontics. Polymethyl methacrylate (PMMA) is commonly used for prosthetic dental applications, including the fabrication of artificial teeth, denture bases, dentures, obturators, orthodontic retainers, temporary or provisional crowns, and for the repair of dental prostheses. Additional dental applications of PMMA include occlusal splints, printed or milled casts, dies for treatment planning, and the embedding of tooth specimens for research purposes. The unique properties of PMMA, such as its low density, aesthetics, cost-effectiveness, ease of manipulation, and tailorable physical and mechanical properties, make it a suitable and popular biomaterial for these dental applications. To further improve the properties (thermal properties, water sorption, solubility, impact strength, flexural strength) of PMMA, several chemical modifications and mechanical reinforcement techniques using various types of fibers, nanoparticles, and nanotubes have been reported recently. The present article comprehensively reviews various aspects and properties of PMMA biomaterials, mainly for prosthodontic applications. In addition, recent updates and modifications to enhance the physical and mechanical properties of PMMA are also discussed.

“…Although GBMs have wide coating applications 9,11,[14][15][16] , the durability and stability are important concern for its long term use. Won et al 46 studied the durability and degradation mechanism of graphene coatings on Cu and found that a few layers thick graphene coating was effective in increasing the durability of the Cu substrate under dry contact sliding.…”

Graphene based materials (GBMs) have potentials for dental and medical applications. GBMs may cause changes in the levels of cytokine released in the body. this study aimed to study the corrosion resistance of graphene oxide (Go) and Go/silver (Go/Ag) nanocomposite coated nickel-titanium (niti) alloy by electrophoretic deposition and to access the viability of human pulp fibroblasts, and the interleukin (IL)-6 and IL-8 expression level. The bare and coated NiTi samples were characterized by scanning electron microscope (SeM), energy-dispersive X-ray spectroscopy (eDS), Raman spectroscopy, surface profilometry, and X-ray diffraction (XRD). The corrosion resistance of the bare NiTi and coated NiTi samples were investigated by potentiodynamic polarization and electrochemical impedance spectroscopy in 3.5% NaCl solution. The cell viability of human pulp fibroblasts was accessed by the treated culture medium of the bare NiTi and coated NiTi alloys containing 1% fetal bovine serum. IL-6 and IL-8 expression levels were studied by human enzyme-linked immunosorbent assay (ELISA). Data were analyzed using One-way ANOVA (α = 0.05). Both the GO-coated NiTi and GO/Ag-coated NiTi alloys showed better corrosion resistance, a lower rate of corrosion, and higher protection efficiency than the bare NiTi alloy. The coated NiTi alloys were biocompatible to human pulp fibroblasts and showed upregulation of IL-6 and IL-8 levels. Nickel-titanium (NiTi) alloy is widely used due to the special properties of superelasticity and shape memory. Common biomedical applications of NiTi alloys include vascular stents, staples, catheter guide wires, orthodontic wires, and endodontic instruments. However, NiTi alloy exhibits corrosion attack compared to stainless steel, cobalt-chrome, or β-titanium and it results in Ni and Ti ions release. It was found that a significant release of Ni and Ti ions from dental alloys in corrosive environment is noted although the amount of Ni ions release diminish with time 1. Another study found that Ni leaching occurred after placement of the NiTi orthodontic archwires, bands and brackets and was associated with an increase of the Ni ion concentration in the patient's saliva which lasted for 10 weeks and then decreased slowly 2. These ions can cause foreign body reactions, allergy, and adverse reactions in the human body, such as stomatitis, burning sensation, angular cheilitis, and loss of taste 3,4. Similarly, Ni along with Co and Cr remains the most common metals associated with surgical implant failure due to metal sensitization 5. Therefore, the surface modifications and/or coatings have an important role in surface improvement and reducing the corrosion and body reactions. Although various polymer coatings have been tried on NiTi alloy, there has always difficult in making a successful coatings 6,7. Graphene is a sheet of sp 2 carbon atoms that creates a 2-D hexagonal honeycomb structure 8. Graphene based materials (GBMs) have been used for fabricating various nanocomposite coatings to improve surface and me...
