The study is devoted to one of relevant topics in orthopaedic dentistry: orthopaedic treatment for fully edentulous patients with application of removable laminar dentures the basis of which is produced from acrylic plastic. The main problem of this approach has been formulated: the possibility of frequent crashing of the basis by the patient within earlier and later periods after the beginning of prosthesis exploitation. Options in prevention of this problem have been considered — reinforcing of the denture basis using standard and individually produced metal meshes — as well as their disadvantages. A study based on longitudinal clinical observation within terms of up to five years of exploitation effectiveness in quartz reinforcing mesh application to removable denture bases as an alternative approach to modern technologies has been carried out. Application features and advantages of this technology have been presented.

Restoration of complete maxillary or mandibular adentia, despite the advances of dentistry nowadays, has always been and is still remaining one of the most challenging among the clinical issues of orthopedic dentistry. The effectiveness of a high-quality complete removable denture is largely predetermined by the properties of the denture base material. However, long experience in manufacturing the dentures has revealed a number of their disadvantages. The development of new denture base materials and their studies have been being carried out for many years. The aim of this work was to investigate the effectiveness of thermoplastic base material "Vertex ThermoSense" (Netherlands) and fluorine-containing acrylic plastic "Ftoraks" (Ukraine) used in manufacturing the dentures for edentulous patients who previously worn full removable dentures made of acrylic plastic over the past 3- 5 years. We examined and treated 43 patients with complete anodontia who went to the orthodontic clinic to order a new denture. We used fluorine-containing acrylic co-polymers "Ftorax" (Ukraine) and polyamide (nylon) "Vertex ThermoSense" (Netherlands), recommended by manufacturers for making removable dentures. We assessed the level subjective satisfaction with new dentures in different follow-up time intervals, checked the restoration of the chewing function in the patients using electromyographic techniques. Clinical findings obtained supported the superiority of Vertex ThermoSense thermoplastic material over fluorine-containing acrylic resins in terms of high functional quality and strength that facilitate the durability of these complete dentures. In addition, the denture base made of "Vertex ThermoSense" does not contain residual monomer, thereby preventing the occurrence of allergic reactions. The results of our work allow us to strongly recommend the material "Vertex ThermoSense" to implement into prosthodontic practice for manufacturing complete removable dentures.

Till present times nutritiology and dietology in dental practice are at rudimentary level. At the same time it is a well-known fact the chewing efficiency is much higher in case of having fixed prosthesis comparing with their removable denture counterpart. As for elderly population nourishment it is important to take into consideration the complexity of receiving of all the necessary nutrients. Quantity and quality of the food diet will directly affect their quality of life. Aim. Development of the functional food diet ration for specific groups of dental patients Materials and Methods. We surveyed 244 patients (84 males, 160 females) in the age range from 60 to 85 years (mean value 75.4+/-2.4) with different types of implant supported prostheses. We used clinical, sociological, nutritiological evaluation methods. Besides that we used GOHAI questionnaire and modified Wolfart questionnaire. Results. We defined basic groups of dental patients who have indications for prescribing functional food diet: a) patients utilizing removable dentures, especially full dentures, in the situation where antagonists would be intact dentition or dental arches with conventional or implant supported fixed bridges; b) patients treated with immediate removable dentures, fixed implant supported prostheses, especially in case of big span bridges with limited amount of fixtures; c) patients using removable implant supported overdentures; d) Patients older than 70 years of age. We established food rations based on intaking soft low viscosity liquid meal. High GOHAI scores (56.1+/-1.49) were the prove of the high efficiency and efficacy of the rehabilitation per se and also of the functional diet regimen recommended to the examined patients. Conclusions. We developed functional food diet taking into consideration the short and long term period after finishing the implant supported or conventional, immediate or delayed prosthetic rehabilitation with the use of total prosthesis predominately for edentulous patients. Incorporation of these types of diet regimen in the rehabilitation plan oriented towards increasing the efficiency of the main treatment arrangements.

Aim: To compare and evaluate clinical experience and graphoanalysis, using House’s classification in assessing the emotional status of completely edentulous patients in success of complete denture. Settings and Design: Comparative analytical study. Methods and Material: 50 completely edentulous patients of age above 45 years (M/F) were taken as subjects. Literate patients were included in the study while incompetent patients and illiterate patients were excluded. Patients were asked to express their expectations regarding the treatment on paper in their handwritings using vernacular language. Subjects were categorized on the basis of age and gender. The handwriting samples were collected and graphoanalysis was done. Statistical analysis used: The resultant data was subjected to statistical analysis using chi square test and spearman's rank correlation test. Results: Considering age, on graphoanalysis (P-18, I-14, E-14, H–4) were found, when compared to Clinical experience (P-23, I-12, E -13, H- 2). While considering gender, on GA (P-18, I-14, E-14 and H-4) were found when compared to CE (P-23, I-12, E-13 and H-2). Chi-square test showed CE and GA were independent of age and gender. Spearman’s rank correlation between CE and GA was 0.217. Conclusions: Clinical experience and graphoanalysis of complete denture patient are independent of Age and Gender. There was a significant correlation between CE and GA, so graphoanalysis can be used for ascertaining the mental attitude of completely edentulous patient.

Ceramic Crown

The subject. Significant preparation of the teeth for metal-ceramic or ceramic crowns in most cases is accompanied by a preliminary devitalization of the teeth, which shortens the period of their survival. The problem of ensuring the vitality of supporting teeth can be solved by amputating only the coronal pulp, which inevitably overheats during preparation, while retaining the root pulp. The skeptical attitude of dentists to vital pulpotomy may be explained by the often unsuccessful (ineffective) use of this method for teeth with already affected pulp. The hope for success in this study is based on the choice of intact teeth for vital pulpotomy of subsequent prosthetics. Urgency. The amputation method of endodontic dentistry is not used for prosthetic purposes. This can be explained by its low efficiency when using teeth with inflamed pulp. The aim of the work is to confirm the effectiveness of vital pulpotomy in a typical dental situation and subsequent prosthetics. Methodology. Clinical observation of the patient before and during 1 year after treatment, with the use of clinical and modern paraclinical methods of examination. Diagnosed. Treatment is planned: removable denture on the upper jaw with a preliminary shortening of the tooth 46 and subsequent use of a metal-ceramic crown. Significant sosotoyanie hard tissues of the tooth 46 and the subsequent preparation for artificial crowns required endodontic-specific training. It was supposed to preserve the root pulp (vital pulpotomy). As a result, there were no complaints at the control examination 1 year after pulpotomy. The pain threshold from the electrode was 11 µa. Summary. The vital pulpotomy of the tooth with intact pulp showed the possibility of its effective prosthetics with an artificial crown while maintaining the viability of the root pulp. The technique of introduction of the electrode into the cavity of the tooth allowed to conduct direct measurements of the pain threshold of the root pulp in the dynamics of (application for invention No. 2017115518/17(026915) from 02.05.2017).

The increasing interest in producing bimetallic nanoparticles and utilizing them in modern technologies sets the demand for fast and affordable characterization of these materials. To date Scanning Transmission Electron Microscopy (STEM) coupled to energy dispersive X-ray spectroscopy is usually used to determine the size and composition of alloy nanoparticles, which is time-consuming and expensive. Here electrochemical single nanoparticle analysis is presented as an alternative approach to infer the particle size and composition of alloy nanoparticles, directly in a dispersion of these particles. As a proof of concept, 14 nm sized Ag0.73Au0.27 alloy nanoparticles are analyzed using a combination of chronoamperometric single nanoparticle analysis and cyclic voltammetry ensemble studies. It is demonstrated that the size, the alloying and the composition can all be inferred using this approach. Thus, the electrochemical characterization of single bimetallic alloy nanoparticles is suggested here as a powerful and convenient complement or alternative to TEM characterization of alloy nanoparticles.

ABSTRACT Purpose To assess edentulous patient awareness, expectations, and source of information about dental implants (DIs). Materials and methods Edentulous patients’ knowledge and awareness in using DIs, as an option in replacing missing teeth, either in implant-supported fixed prosthesis or implantsupported overdenture, were evaluated through a standardized self-explanatory questionnaire distributed in three places: King Saud Hospital, AL Harkan Private Dental Clinics (in Unaizah), and College of Dentistry, Qassim University. The questionnaires were either handed to the patients during their regular dental visits or asked by the dentist. A total of 178 subjects were included in this survey. Results About 93.3% of participants were aware of DIs, with statistically significant difference between the study groups (p = 0. 012). The participants’ friends and relatives were the main source of information (49.40%), followed by dentists (33.70%). Approximately 41.60% were moderately informed about DIs. Over one-third of patients expected an implant to require more care than natural teeth (39.80%). About 65.3, 73.6, and 80% of single missing, partially, and completely edentulous patients respectively, preferred to have their teeth replaced with DIs. Improvement in function was the predominant reason for completely edentulous patients (57.9%) to consider DIs, while 37.6 and 41.4% of single missing and partially edentulous patients were considered DIs to avoid adjacent teeth damaging. Fear of surgical risks was the major factor in preventing patients from choosing DIs (13.5%), followed by high cost (9.6%) and unknown side effects (6.2%). Conclusion There was a high awareness about DIs among removable denture patients; however, this awareness was associated with a low level of accurate information. Recommendations There is a need to provide more accurate information about DIs to the patients by the dentists. How to cite this article Mekkawy MA, Almutairi HA.

Nonresorbable sintered ceramic hydroxylapatite (HA) is widely employed for filling defects in jaw bone. The small particles used for alveolar ridge augmentation in edentulous patients or for infrabony defects due to periodontal disease tend to scatter when implanted using water or saline as the vehicle. Larger blocks of this material used for filling sockets after tooth extraction don't fit well. Studies in our laboratory where we compared bovine serum albumin, collagen and plaster of Paris as binders to prevent particle scatter during implantation suggested that plaster was most useful for this purpose. In addition to preventing scatter of the particles, plaster enables the formation of implants of any size and.shape either prior to or during surgery. Studies with the PATS reaction have indicated that plaster acts as a scaffold for the incorporation of HA particles into bone in areas where the implant contacts either host bone or periosteum. The shape and integrity of the implant is maintained by the plaster component until it is replaced over a period of days by fibrovascular tissue.
