The advantages of plaster of Paris as a splinting material are 1) its ability to intimately conform1, 23, 30; 2) the decreased possibility of pressure areas, because of
Plaster of Paris, a highly compliant material, is often overlooked in the splinting of hand patients. This article enumerates the advantages of plaster of Paris and

Abstract. This article examines the concept of tissue adaptation in response to the application of plaster of Paris splints and casts. A review of the history of plaster of Paris

4. Add dry plaster and silica to the water. Gradually pick up handfuls and sift the powder through your fingers. This will break up any clumps, letting the powder fall into the water. Work quickly, but avoid
Preparation of Plaster of Paris: It is prepared by heating gypsum (calcium sulfate dehydrate) up to 140 180 °C or 248–356 °F. Plaster of Paris is obtained in the form of a finegrained
Plaster of Paris is manufactured by heating gypsum at 373 393 K or 150° C/300° F. CaSO4·2H2O + heat → CaSO4·0.5H2O + 1.5H2O (discharged as steam) On
Plaster of Paris(PoP) is a brittle, porous solid, easy to shape, which has potential as a model . as well as limiting crack length in toughening composites. Compliant inclusions and voids can
Plaster of Paris is calcined gypsum (roasted gypsum), ground to a fine powder by milling. When water is added, the more soluble form of calcium sulfate returns to the relatively insoluble form, and heat is produced [2(CaSO 4 ½H 2 O) + 3H 2 O → 2(CaSO 4 2H 2 O) + Heat]. The setting of unmodified plaster starts about 10 min after mixing and
Distal end of the implant was then fixed into a cylindrical chamber using Plaster of Paris (Figure 4). Implants were positioned vertically so that working stem length remains 85 mm. Mechanical testing was done using a commercial universal testing machine with 5 kN load cell (Tinius Olsen Ltd., UK) ( Figure 4 ).
Method #3. Removal of the molded object from the mold is the most difficult task to perform. The plaster can take anywhere between a few minutes to an hour to dry up. The basic drying period of the object is determined by its
