QUESTIONNAIRE SURVEY ON CRANIOMANDIBULAR DISORDER ISSUES IN STUDENTS' AND POST-GRADUATE TRAINING IN BULGARIA.

The prevalence of craniomandibular disorders (CMD) among the Bulgarian population as well as the risk factors for unlocking bruxism and bruxomania mechanisms pose a demand for education on these issues reflecting modern science. The authors' aim is to examine the subjective assessment of participants in “DAYS OF PROSTHETICS, Sofia, 15 -16 March 2014”, regarding: 1.Prevelance of CMD in the country; 2. Education and training of students and post-graduates in the issues related to diagnostics and treatment of craniomandibular disorders; 3. Theoretical background for successful treatment of patients with bruxism and bruxomania. Materials and methods: For the purpose of the present research 192 participants have been surveyed - among them 163 are dentists and 29 are students in the 4th and 5th year of study. The survey feedback has been obtained via an anonymous questionnaire consisting of 8 questions targeted at dentists' assessment of CMD prevalence and distribution, training in CMD issues in Bulgaria and the treatment of patients with bruxism and bruxomania. The results obtained indicate that 84.0% - 93.1% (95% CI) of respondents, working as dentists in the country, expressed the view that students' curriculum lacks an overall concept for training them in the diagnostics and treatment of CMD. 79.6% - 90.2% (95% CI) of participants, dentists in the country, define post-graduate training in CMD as insufficient or lacking. Conclusion: The development and promotion of a working platform for early screening, diagnostics and treatment of CMD for timely referral to a specialized treatment is necessary and expected by the professional community in our country

Application of Soft Relining Materials in Dental Medicine - Clinical Results

Aim: The objective of this study was to carry out an in vivo investigation of patients wearing dentures relined with soft materials, assuming their positive and negative alterations in time. Materials and methods: A direct survey method was used to gather data from 23 patients included in this study (11 male and 12 female patients). Twenty-seven dentures were made (12 partial and 15 total dentures) 9 of which in chairside procedures, 11 - in a laboratory, and 7 were made using the direct-indirect method. Patients were included in regular follow-ups at one month and six months, and at one, two, and three years after dentures delivery. The study started in 2014 and continued till 2017. The materials we used in the study were quite appropriate to this type of investigation, following the proper clinical and laboratory protocols. The two most commonly used groups of relining materials on the dental market nowadays were tested. Results and discussion: All participants completed questionnaires which included questions related to changes in retention and stability of the relined dentures, changes in color and softness, in bond strength, and inflammation. The majority of patients were satisfied with the new dentures, but they also reported some problems concerning the staining and hardness of some of the investigated materials. Conclusion: There were no significant differences in the behavior of the different groups of materials at six months. After six months we observed decline in the bond strength of the vinyl-polysiloxane (VPS) materials, as well as increased staining and hardness in the poly-methyl-methacrylate (PMMA)

Recent Advances in 3D Printing of Polymers for Application in Prosthodontics

Contemporary mass media frequently depict 3D printing as a technology with widespread utilization in the creation of dental prosthetics. This paper endeavors to provide an evidence-based assessment of the current scope of 3D printing’s integration within dental laboratories and practices. Its primary objective is to offer a systematic evaluation of the existing applications of 3D-printing technology within the realm of dental prosthetic restorations. Furthermore, this article delves into potential prospects, while also critically examining the sustained relevance of conventional dental laboratory services and manufacturing procedures. The central focus of this article is to expound upon the extent to which 3D printing is presently harnessed for crafting dental prosthetic appliances. By presenting verifiable data and factual insights, this article aspires to elucidate the actual implementation of 3D printing in prosthetic dentistry and its seamless integration into dental practices. The aim of this narrative review is twofold: firstly, to provide an informed and unbiased evaluation of the role that 3D printing currently plays within dental laboratories and practices; and secondly, to instigate contemplation on the transformative potential of this technology, both in terms of its contemporary impact and its future implications, while maintaining a balanced consideration of traditional dental approaches
