Abstract INDALLOY No. 255 is a fusible alloy that melts at 255 F. This low-melting eutectic alloy provides scientists and engineers with an easily castable material that is ready for use as soon as it freezes. It can be recovered easily and recycled into new uses any number of times. Among its many applications are proof-casting, liquid seals for heat-treating furnaces, non-shrinking patterns and dental models. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, forming, heat treating, and machining. Filing Code: Bi-18. Producer or source: Indium Corporation of America.

Abstract CERROLOW-117 Alloy is a bismuth-base eutectic alloy that melts at 117 F (47 C). Its low melting temperature and controlled-shrinkage characteristics make it very useful in industry for such applications as proof casting in tool and die shops, dental models and low-temperature solder. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, forming, heat treating, and machining.

Objective: This study sought to investigate the association between maxillary growth and speech outcomes for children with a repaired unilateral cleft lip and palate (UCLP) at 5 years of age. Participants: In all, 521 children (180 females and 341 males) with a nonsyndromic complete UCLP, born between 2007 and 2012 in England, Wales, and Northern Ireland were included in this study. Outcome Measures: Maxillary growth was analyzed using dental models scored by the 5-Year-Olds’ index, and perceptual speech analyses were scored by the Cleft Audit Protocol for Speech – Augmented rating. Results: Forty-one percent of the children achieved good maxillary growth (scores 1 and 2 on 5-Year-Old’ index). Fifty percent of the children achieved normal speech (achieving UK speech standard 1). Maxillary growth was not found to have an impact on speech outcome when described by the 3 UK National Cleft Lip and Palate Speech Audit Outcome Standards. Analysis according to individual speech parameters showed dentalizations to be less prevalent in children with good maxillary growth compared to fair and poor growth ( P = .001). The remaining speech parameters within resonance, nasal airflow, and articulation categories were not significantly associated with maxillary growth. Conclusion: The findings from this study suggest that children with a history of complete UCLP, who have poor maxillary growth, are not at a higher risk of having major speech errors compared to children with good or fair maxillary growth at 5 years of age.

Background: Due to advances in digital technology, it is possible to obtain digital dental models through intraoral scanning. The stereolithographic data collected from the scanner can subsequently be printed into a three-dimensional dental model in resinic material. However, the accuracy between digital dental models and printed dental models needs to be evaluated since it might affect diagnosis and treatment planning in orthodontic treatment. This study aimed to evaluate the accuracy of digital models scanned by a Trios intraoral scanner and three-dimensional dental models printed using a Formlabs 2 3D printer in linear measurements and Bolton analysis. Methods: A total of 35 subjects were included in this study. All subjects were scanned using a Trios intraoral scanner to obtain digital study models. Stereolithographic data from previous scanning was printed using a Formlabs 2 3D printer to obtain printed study models. Mesiodistal, intercanine, intermolar, and Bolton analysis from all types of study models were measured. The intraclass correlation coefficient was used to assess intraobserver and interobserver reliability. All data were then statistically analyzed. Results: The reliability tests were high for both intraobserver and interobserver reliability, which demonstrates high reproducibility for all measurements on all model types. Most of the data compared between study models showed no statistically significant differences, though some data differed significantly. However, the differences are considered clinically insignificant. Conclusion: Digital dental models and three-dimensional printed dental models may be used interchangeably with plaster dental models for diagnostic and treatment planning purposes. Keywords: Accuracy, 3D printing, digital dental model, printed dental model.

Objective: the objective of this literature review was to catalog and describe observational scientific studies on the planning of removable partial dentures, based on the panorama of rehabilitation in the last 20 years in Brazil. Methodology: As databases Scielo, Pubmed, Google Scholar, VHL; as well as the terms used in this search were: removable partial denture, dental prosthesis planning and dental models. The inclusion criteria in this study were observational studies carried out based on data obtained in Brazil; articles that address the variables under study: planning, quality of the models and dental preparations published between 2000 and 2020. The exclusion criteria for this work were literature reviews, clinical cases, letters to the editor, opinion articles (low scientific evidence); literature with data from other countries; articles not available in full by the databases; articles addressing the planning of unconventional PPRs. The selection of articles was carried out based on abstracts. Results: The selection resulted in 11 researches on the theme, the works showed a high prevalence of the absence of planning (drawing) and dental preparations, niches and guide plans, in addition to plaster models in poor conditions. It being observed that the responsibility in the elaboration of the design of the metallic structure by the dentist has been delegated to the technician in dental prosthesis. Conclusion: Based on the methodology used in this literature review, the findings showed a bleak outlook in Brazil, regarding the planning of the removable partial denture that is neglected by the dentist.
