A Bibliometric Analysis of Removable Partial Denture-related Research in Dentistry

To introduce a method of digital modeling and fabricating removable partial denture (RPD) frameworks using self-developed software for RPD design and rapid manufacturing system. The three-dimensional data of two partially dentate dental casts were obtained using a three-dimensional crossing section scanner. Self-developed software package for RPD design was used to decide the path of insertion and to design different components of RPD frameworks. The components included occlusal rest, clasp, lingual bar, polymeric retention framework and maxillary major connector. The design procedure for the components was as following: first, determine the outline of the component. Second, build the tissue surface of the component using the scanned data within the outline. Third, preset cross section was used to produce the polished surface. Finally, different RPD components were modeled respectively and connected by minor connectors to form an integrated RPD framework. The finished data were imported into a self-developed selective laser melting (SLM) machine and metal frameworks were fabricated directly. RPD frameworks for the two scanned dental casts were modeled with this self-developed program and metal RPD frameworks were successfully fabricated using SLM method. The finished metal frameworks fit well on the plaster models. The self-developed computer aided design and computer aided manufacture (CAD-CAM) system for RPD design and fabrication has completely independent intellectual property rights. It provides a new method of manufacturing metal RPD frameworks.

Objectively evaluating an individual's capacity for food fragmentation (masticatory performance) is crucial for understanding oral physiology and dental rehabilitation processes. Our aim was to conduct a bibliometric analysis of the literature focusing on masticatory performance. We conducted a survey in Web of Science up to August 31, 2024, applying specific category filters. Two calibrated reviewers manually tabulated the data, extracting information on title, authorship, keywords, institutions, countries, number of citations, year of publication, journal title, study design, masticatory test, population, and dentition status. VosViewer software generated collaborative network maps, while JAMOVI was used to perform ANOVA and Poisson regression analyses. The selection process resulted in 814 articles published between 1950 and 2024, with a recent increase to at least 50 articles per year. The average impact factor was 3.16, with around 30 citations per article. Citations were significantly influenced by the masticatory performance technique, publication year, and journal impact factor. The comminution test was the most prevalent (n = 411). Most studies focused on adults (n = 420) and older adults (n = 361), in which natural dentition (n = 404) and complete dentures (n = 214) were the most widely assessed parameters. The most frequent study designs were cross-sectional (n=489) and prospective (n = 145). The leading countries were Japan (n=202), Brazil (n=134), and the Netherlands (n = 69), and the Journal of Oral Rehabilitation was the most recurrent journal (n = 162). This study highlights the growing interest in evaluating masticatory performance, with a significant increase in publications over the years. This study highlights the need for further research involving children and longitudinal study designs, as well as studies evaluating rehabilitations with removable partial denture and implant-supported prostheses.

IntroductionThe conventional method for teaching removable partial denture (RPD) design using a pencil drawing on a solid cast has always been the basis for teaching RPD design in most dental schools at both the undergraduate and graduate levels. This does not apply to RPD fabrication technology, as more laboratories have recently adopted more efficient and versatile digital techniques to design and fabricate RPD frameworks.MethodsAt the University of Iowa College of Dentistry, we created a pilot workshop to assess the efficiency of a new approach to teaching RPD design utilizing this new digital RPD technology as a teaching tool for graduate prosthodontics residents. Three first-year prosthodontics residents were enrolled in the workshop, which involved learning the new digital workflow of designing RPD.ResultsThis new teaching approach very successfully achieved its educational goals. The residents reported that the digital RPD teaching approach enriched their knowledge and deepened their understanding of RPD design.DiscussionThe technique garnered significant interest from the students and seemed to also increase their understanding of the steps involved in RPD fabrication as well as the different components of the RPD.

Additive manufacturing (AM) often referred to as 3D printing (3DP) has shown promise of being significantly viable in the construction of cobalt-chromium removable partial denture (RPD) frameworks. The current paper seeks to discuss AM technologies (photopolymerization processes and selective laser melting) and review their scope. The review also discusses the clinical relevance of cobalt-chromium RPD frameworks. All relevant publications in English over the last 10 years, when the first 3D-printed RPD framework was reported, are examined. The review notes that AM offers significant benefits in terms of speed of the manufacturing processes however cost and other aspects of current technologies remain a hindrance.

Aim To assess the impact of removable partial denture (RPD) on the quality of life in patients wearing RPD after 1 year of use. Materials and methods Observational study was conducted on a convenience sample of 50 patients who were delivered RPD in the Department of Prosthodontics. Oral health impact profile (OHIP-14) (translated to Tamil, but not validated) was used to measure the impact. Data were collected using telephonic interview at 6 months after the insertion of RPD (T1) and (T2) at the end of 1 year (time interval of 6 months) prospectively. Significant differences for prevalence, mean OHIP-14 scores, and extent were determined using t test. Results Increase in mean OHIP-14 scores and extent was observed at T1 and T2. Almost all the dimensions of OHIP-14 had higher scores at T2 except psychological discomfort. Physical pain, physical disability, and psychological disability were dimensions with significant differences (p < 0.05). A fivefold increase in proportion was observed for physical disability and psychological disability among those reporting impacts as “very often/fairly often.” Conclusion The RPD had detrimental effect on wearer's quality of life with significant impact for painful aching in the mouth, feeling a bit embarrassed, and difficulty in chewing. Wearing RPD significantly increases the extent of impacts within a short time span of 6 months. Clinical significance The RPD can have a considerable impact on quality of life, which can either ameliorate or deteriorate. Patients have to be counseled periodically at subsequent recall visits and their quality of life measured, which will enable clinicians to rectify, assess, and provide adequate care to improve the overall quality of life.

Milling and selective laser melting (SLM) technology have become new options for removable partial denture (RPD) processing. However, whether milling and SLM technology has an impact on the properties of RPD remains unclear, which is also the aim of our study. To investigate the effects of milling and SLM technology on pure titanium, mechanical property, corrosion resistance, and anti-adherence of specimens were evaluated, and specimens processed by lost-wax casting were used as control. Compared with casting and milling groups, the SLM group showed enhanced Vickers hardness (402.1 ± 13.0HV), tensile stress (694.4 ± 4.5MPa), and larger electrochemical capacitance arc radius compared with casting and milling groups. A series of adhesion-related genes (Als1, Als3, and HWP1) of Candida albicans cultured on SLM specimens were upregulated for more than two times that of casting and milling groups. However, images from scanning electron microscopy and confocal laser scanning microscopy exhibited similar biofilm morphology and biomass of C. albicans on a titanium disk processed by casting, milling, and SLM. Dwindled water contact angle (64.7 ± 0.6°) and higher TiO2 constituents (40.82%) in the SLM group might lead to the incompatibility of genetic expression and biofilm generation. Our findings indicated that SLM is an ideal process to produce titanium dentures, providing a reference on the selection of processing technology for dentists.

The objective of the study was to compare the retentive force and deformation of conventional casting and selective laser melting (SLM) cobalt-chromium (Co-Cr) clasps assembly of removable partial dentures (RPD) following recurrent insertion and removal forces. A total of 12 RPD samples were used in this study, which were divided equally into two groups: Group A (indirect digital conventional casting) and Group B (direct digital SLM) Co-Cr clasp assembly. The retention was measured using a universal testing machine after the recurrent removal and insertion of the RPD. Deformation was measured using Geomagic Control X professional metrology software. The retention and deformation data were compared between the two groups using an independent sample t-test. The association between the variables was studied using the Pearson correlation test. A statistical significance was established at P < 0.05. A statistically significant difference in retention was observed between the two groups. Direct digital SLM Co-Cr clasp assembly showed higher retention and lower distortion compared to the indirect digital conventional casting Co-Cr clasp assembly. A significant negative correlation (correlation coefficient=-0.807, p-value = 0.004) between deformation and retention suggests that increased deformation reduces the retention. The direct digital SLM Co-Cr clasp assembly in the RPD showed higher retentive force and lower deformation than the indirect digital conventional casting Co-Cr clasp assembly in the RPD.

Heritage gardens represent the cultural heritage pride of many nations, and their sustainable preservation has garnered widespread academic attention globally. Despite numerous qualitative reviews, a comprehensive quantitative analysis of heritage garden preservation literature from 2004 to 2024 is lacking. This study examines the dynamic evolution of heritage garden conservation (2004–2024) through bibliometric analysis, focusing on Research Activity and Impact, Cooperation Networks, and Knowledge Structure and Thematic Evolution. To achieve this goal, this study conducted a bibliometric analysis using the Web of Science Core Collection database. Initially, 1,540 documents were retrieved. After excluding irrelevant categories and conducting a manual review of titles, abstracts, and keywords to ensure relevance, 774 articles were selected for analysis. The analysis utilized bibliometric software tools such as VOS viewer, CiteSpace, and Biblioshiny. The results initially reveal that the period from 2010 to 2021 marked a significant increase in publication volume within the field of heritage gardens, although only 2.4% of the papers were reviews. Landscape Urban Planning and Geoheritage emerged as the most influential journals, based on their high local citation counts within the field. Additionally, collaboration networks indicated that scholars from the United States and China published the most papers, with Canadian scholars’ works having significant impact. Influenced by the evolving concepts of technology, politics, and cultural heritage, the analysis of knowledge structure and theme evolution identified ecosystem services, user perceptions, and cultural landscape impacts as recent hot topics. Future research on the sustainable preservation of heritage gardens should focus more on balancing urban development, incorporating sustainable management, and digital restoration through quantitative methods. In summary, this study offers insights into the global evolution of heritage garden preservation from 2004 to 2024, providing a valuable resource for future research and policy-making.

Process parameter optimization for removable partial denture frameworks manufactured by selective laser melting

To investigate the prevalence and severity of oral health-related quality of life in patients treated with removable partial dentures at a publicly-funded dental hospital. The association between patients' demographic profiles, denture-related, variables and oral health-related quality of life was also investigated. A questionnaire was designed to investigate the use and satisfaction of removable partial dentures, and oral health-related quality of life of removable partial denture wearers using the Oral Health Impact Profile-14. The questionnaire was administered to 740 randomly-selected patients who received removable partial dentures during 2005-2008. The response rate was 31.35%. Non-parametric tests and a logistic regression model were used to analyze the association between denture-related variables and oral health-related quality of life. A question on symptoms unrelated to dentures was also analyzed. The Oral Health Impact Profile-14 prevalence calculated was 43.1%. The removable partial denture experience and frequency of use was inversely associated with Oral Health Impact Profile-14 scores. Metal-based removable partial dentures were associated with lower Oral Health Impact Profile prevalence and severity scores. No significant association was found between demographic profile, circumstance for provision of removable partial dentures and Oral Health Impact Profile-14 score. The participants of this study indicated that perceived denture performance, removable partial dentures material, experience, and frequency of use are associated with oral health-related quality of life.

ObjectivesThe purpose of this systematic review and meta‐analysis was to compare implant‐supported removable partial dentures (ISRPDs) with distal extension removable partial dentures (DERPDs) in terms of patient‐reported outcome measures (PROMs: patients' quality of life and satisfaction) and to determine mechanical and biological complications associated with ISRPDs.Material and MethodsAn electronic search was performed on four databases to identify studies treating Kennedy class I or II edentulous patients and which compared ISRPDs with DERPDs in terms of PROMS and studies, which evaluated mechanical and biological complications associated ISRPDs. Two authors independently extracted data on quality of life, patient satisfaction, and biomechanical complications from these studies. The risk of bias was assessed for each study, and for PROMs, the authors performed a meta‐analysis by using a random‐effects model.ResultsThirteen articles were included based on the selection criteria. The difference in mean scores for quality of life (30.5 ± 1.8; 95% confidence interval [CI], 24.9–36.1) and patient satisfaction (−20.8 ± 0.2; 95% CI, −23.7 to −17.8) between treatments with conventional and implant‐supported removable dentures was statistically significant (p < .05). Implant‐supported removable dentures improved patients' overall quality of life and satisfaction. Some mechanical and biological complications, such as clasp adjustment, abutment or implant loosening, marginal bone resorption, and peri‐implant mucositis, were noted in ISRPDs during patient follow‐up. Studies assessing PROMs were very heterogeneous (I 2 = 65%, p = .85; I 2 = 75%, p = .88).ConclusionsISRPDs significantly improved quality of life and patient satisfaction. Some mechanical and biological complications have been associated with ISRPDs treatment, requiring regular monitoring of patients to avoid the occurrence of these complications.
