A technique is described to obtain a 3D‐printed custom tray for complete dentures through open‐source, free software and additive manufacturing. This approach enables the production of custom trays in a cost‐effective and optimized manner. A three‐dimensional (3D) digital cast is obtained by photogrammetry and later used to design a digital custom tray. Then, the digital custom tray is manufactured by a 3D printer to be used in clinical procedures. This technique is a clean, rapid, and low‐cost alternative to the traditional technique.

Metrics derived from online social platforms indicate current interest in a specific topic. This study aimed to analyze the characteristics and social interest in scientific publications on bruxism using an altmetric analysis. A search was conducted in August 2024 in the Dimensions database. The following data were extracted: altmetric attention score (AAS), citations, year, language, access type, study design, topic (general objective and age group), journal, country, institution, and authors. VOSviewer was used to generate collaborative networks, whereas Google Trends was consulted to assess public interest in bruxism-related research. A Spearman correlation analysis was performed to establish the relationship between AAS and citations. A total of 196 studies published between 1992 and 2024 were included. The most widely accessed study had an AAS of 393. Significant interest in bruxism was observed among Mendeley, news outlets, and X users. Most studies were observational (n = 99), addressing the etiologic factors of bruxism (n = 75) and focusing primarily on the adult population (n = 148). The Journal of Oral Rehabilitation stood out as the most relevant journal (n = 36). Most articles were published in Brazil (n = 40), and Lobbezoo was the most frequent author (n = 27). VOSviewer revealed significant collaborations among authors. Most studies were not openly accessible (n = 105). A very weak positive correlation (r = 0.042) was observed between AAS and the number of citations. This study highlighted a social interest in scientific publications on bruxism, particularly those addressing etiologic factors.

The escalating influx of patients with temporomandibular disorders and the challenges associated with accurate diagnosis by non-specialized dental practitioners underscore the integration of artificial intelligence into the diagnostic process of temporomandibular disorders (TMD) as a potential solution to mitigate diagnostic disparities associated with this condition.

OBJETIVO: Esse estudo avaliou a qualidade de vida relacionada à saúde bucal (QVRSB) e fatores associados em 282 idosos (≥60 anos) de Veranópolis/RS.MÉTODOS: Exame clínico e um questionário estruturado foram aplicados. A variável dependente foi QVRSB, mensurada pelo instrumento OHIP-14. A amostra foi dividida em dois grupos: baixo impacto (aqueles que responderam nunca ou raramente em todas as questões) e alto impacto (aqueles que responderam às vezes, repetidamente ou sempre em pelo menos uma questão). Associações foram realizadas por meio da regressão de Poisson com variância robusta.RESULTADOS: Média de OHIP-14 foi de 3,76±6,22. Indivíduos aposentados que mantiveram ou não atividade laboral apresentaram 27,6% (p=0,036) e 38,5% (p=0,026), respectivamente, menor razão de prevalência (RP) para maior impacto quando comparados com indivíduos não aposentados. Aqueles sem halitose apresentaram 27% (p=0,014) menor RP para alto impacto na QVRSB quando comparados com aqueles com halitose. Maior número de dentes presentes foi associado com menor RP de pertencer ao grupo com maior impacto na QVRSB (p=0,009).CONCLUSÕES: Presença de maior número de dentes, ausência de halitose autorreportada e aposentadoria, com ou sem atividade laboral, foram associados com menor impacto na QVRSB.
