One can read the creative and making processes in the plaster models left by the sculptor. Hans/Jean Arp and Mari Andriessen provide excellent examples in the Gipsotheek collection (Museum Beelden aan Zee). Although Andriessen and Arp had very different sculptural ideas, their creative and making methods were sometimes similar: working in models, reworking, taking parts they liked and reintegrating them into other models. Of course, they ended up with very different results. The plaster sculptures are mostly steppingstones on the way to a final sculpture. This emphasizes the flexibility of pla

Alginate, discovered in 1881 by British chemist E.C.C. Stanford, is a polysaccharide isolated from seaweed. Since its introduction into dentistry in 1940, it has been used as an impression material due to its hydrophilic and hydrophobic properties, which allow dimensional changes during impression and solidification. For optimal impression, type 3 plaster is recommended, which presents lower expansion and longer setting time, ensuring dimensional accuracy. In addition, the stability of the dental model is crucial, including mechanical and dimensional strength. Plastic and metal trays offer dif

The comparison between conventional plaster cast models and digital models in the accuracy of prosthetic fitting is a relevant topic in modern dentistry. Several studies have shown that digital models, obtained by intraoral scanning, have advantages in terms of accuracy, processing time, and patient satisfaction over conventional plaster models. While both methods can be effective, digital models offer greater flexibility, allowing for better fitting of prostheses, with fewer impression errors and greater reproducibility.

Painters used plaster casts to proclaim their erudite knowledge of antiquity and of Renaissance sculpture that emulated ancient models. Plaster casts also provided a means for ambitious painters to communicate their personal and aspirational ties to other masters.

The integration of computational intelligence and augmented reality has become increasingly prevalent in dental practices. Three-dimensional (3D) printing techniques have now become routine in orthodontics, prosthetics, and maxillofacial surgery. The objective of this study is to assess the effectiveness of stereolithography (SLA) printed models compared to traditional plaster casts over a three-year period. The experimental dataset consisted of 36 orthodontic patients, each with SLA printed models and plaster casts for both the upper and lower jaws, resulting in a total of 72 scans in the for

Abstract Background Digital copies of study models may avoid the storage and retrieval issues of plaster study models, but measurements made on digital models may not be as accurate as measurements made on traditional study models. Aim To determine the reliability and validity of tooth size–arch length discrepancies (TALD), irregularity indices and arch lengths (four- and six-segment analyses) measured directly on study models with digital calipers with the same measurements measured on digital copies of the study models with proprietary software. Methods The irregularity indices and TALDs (fo

Orthodontic treatment planning is a practice that depends on the accuracy of teeth and dental arches’ size measurement. The purpose of the study is to compare the accuracy and the duration of teeth and dental arches’ measurement, utilizing different approaches from conventional plaster models to virtual 3D models obtained by intraoral and extraoral scanners. Fifteen patients were included in the study (7 males, 8 females, mean age 21.7 ± 0.7 years), with a moderate anterior teeth crowding and class I Angle’s classification of malocclusion. Plaster models, as well as virtual 3D scans were obtai

Abstract Does the materiality of a three-dimensional model have an effect on how this model operates in an exploratory way, how it prompts discovery of new mathematical results? Material mathematical models were produced and used during the second half of the nineteenth century, visualizing mathematical objects, such as curves and surfaces—and these were produced from a variety of materials: paper, cardboard, plaster, strings, wood. However, the question, whether their materiality influenced the status of these models—considered as exploratory, technical, or representational—was hardly touched

The quality of fit of a trans-tibial patellar-tendon-bearing (PTB) socket may be influenced by consistency in casting, rectification or alignment. This paper quantifies, for the first time, the variations in the rectified casts between two experienced prosthetists and the variation between the rectified casts of each individual prosthetist. Prosthetists A and B observed the hand casting of a typical trans-tibial amputee. Each prosthetist was supplied with 5 previously measured duplicated plaster models. The two prosthetists rectified the supplied plaster models based on their own interpretatio

Wisbech and Fenland Museum holds much of interest. The collection includes a great many plaster and lead dinosaur and mammal models. The plaster dinosaur models are apparently exact replicas of those reconstructed by Waterhouse Hawkins at Crystal Palace, under the direction of Richard Owen, in 1852-1854. They range in size up to about 40cm long (Figs. 1, 2) and are constructed in plaster, probably from moulds, with crests inset in lead. In addition there are some lead mammals and marine reptiles of various sizes - the ichthyosaurs also appear to be replicas of the Crystal Palace models and bea

Abstract The method of determining the accuracy of polymer molds in plaster forms has been discussed. Distortion of the surface of molds and plaster molds has been assessed. It has been found that the presence of monolithic and porous structure in the samples does not change the accuracy of the surfaces when forms are prepared for removing the material of the model. It has been found that in case of full-mold casting it is more expedient to form the mold cavity with cellular adjustable structures of molding prototypes.
