Nowadays, the problem of prosthetic with non-removable orthopedic structures is quite common and is widely described in domestic and foreign literature. Prosthetics of non-removable structures of prosthetics has a number of advantages: complete rehabilitation of biting function, chewing efficiency, aesthetic norm of a smile. Invisible prosthesis designs, usually small in size, have a short period of psychological and physiological adaptation, which has a good reflection on their long-term use by the patient. The examination of dental patients in the clinic of orthopedic dentistry with unsatisfactory results of prosthetic dentures after 5 years with orthopedic treatment allowed to highlight the main indicators of inapplicability regarding the further use of dentures in terms of biocompatibility, mechanical strength and aesthetic properties. The main aim of the study was to improve the quality of patients’ treatment by identifying the causes of treatment complications by an orthopedist using the method of comparative analysis during the examination of patients with unsatisfactory results of dentures using permanent dentures. To identify the causes of complications of orthopedic treatment, a clinical examination of patients with unsatisfactory results of treatment with permanent constructions of dentures on a cast base was performed. The criteria for evaluation were the following indicators: bad breath, gums pain and bleeding, pain and mobility of the supporting teeth, pain under the intermediate part, metallic taste, pain in the blood vessel, darkening of the lining, chipping the lining, obscuring gums, excessive abrasion, and cleavage. From anamnesis and records in the history of the disease, the period of difficulty was determined. Our research results indicate that a significant part of ineffective treatment is due to the wrong choice of auxiliary and structural materials. Given that the choice of materials is performed arbitrarily, in almost half of cases, taking into account the wishes of patients and their financial capabilities, including the physical, mechanical and clinical and technological characteristics of dental materials, in our opinion, it is necessary to create a computer model of rational choice of material, therapeutic and prophylactic measures to improve the effectiveness of orthopedic treatment for patients with defects in hard tissues of teeth and dentition with non-removable structures. The complex of the following studies will allow the orthopedic dentist to continue improving the quality of patients’ treatment at the clinical stages of treatment with non-removable dentures.

Abstract Surface modification by non-thermal atmospheric plasma (NTAP) treatment can produce significantly higher carboxylic groups on the nanofibers (NF) surface, which potentially can increase biomineralization of NF via promoting glutamic acid (GLU) templated peptide conjugation. Herein, electrospun poly(lactide-co-glycolide) (PLGA) scaffolds were treated with NTAP and conjugated with GLU peptide followed by incubation in simulated body fluids for mineralization. The effect of NTAP treatment and GLU peptide conjugation on mineralization, surface wettability and roughness were investigated. The results showed that NTAP treatment significantly increased GLU peptide conjugation which consequently enhanced mineralization and mechanical properties of NTAP treated and peptide conjugated NF (GLU-pNF) compared to neat PLGA NF, NTAP treated NF (pNF) and GLU peptide conjugated NF (GLU-NF). The effect of surface modification on human bone marrow derived mesenchymal stem cells adhesion, proliferation and morphology was evaluated by cell proliferation assay and fluorescent microscopy. Results demonstrated that cellular adhesion and proliferation were significantly higher on GLU-pNF compared to NF, pNF and GLU-NF. In summary, NTAP treatment could be a promising modification technique to induce biomimetic peptide conjugation and biomineralization for bone tissue engineering applications.

Grid Surface

Atmospheric pressure plasmas have been widely applied in surface modification and biomedical treatment due to its ability to generate highly reactive radicals and charged particles. In cryogenic electron microscopy (cryo-EM), plasmas have been used in eliminating the surface contaminants as well as generating the hydrophilic surface to embed the specimen on grids. Particularly, plasma treatment is a prerequisite for negative stain and quantifoil grids,which are coated with hydrophobic carbon on the grid surface. Here we introduce a nonthermal atmospheric plasma jet system as an alternative new tool for surface treatment. Unlike the conventional glow discharger, we found that the plasma jet system successfully cleans the grid surface and introduces hydrophilicity on grids in the ambient environment without introducing a vacuum. Therefore, we anticipate the plasma jet system will be beneficial in many aspects, such as cost-effective, convenient, versatile, and potential applications in surface modification for both negative stain and cryo-EM grid treatment.
