This research evaluates the behavior of plaster with a water-repellent additive when submitted to natural aging process. Casting and silane/siloxane-based were used as materials. The water/plaster ratio was set at 0.7 contents 0.2% 0.4% used, in relation mass. Plaster pastes without (reference) containing mass evaluated ‘zero’ age after 30, 60, 90, 120, 150 days aging. After aging, it observed ...

Objectives: To assess the eff ect of pouring time on dimensional changes alginate impression material after disinfection.Materials and Methods: A total twenty impressions were made using material. The divided into four groups designated as A, B, C D. Group (control) poured with dental stone immediately rinsing tap water. In group B D applying disinfectant spray at 10mins 1hrdelay. Group-C one h...

Aims and Objectives: To conclude on superior method of model fabrication compare accuracy the reliability measurements obtained 3D scanned models to conventional models. Materials Methods: A total 20 orthodontic study were from department orthodontics dentofacial orthopaedics with a full set permanent teeth right first molar left no anomalies crown. The plaster measured nearest 0.01 mm using Ae...

plasters are produced from a light refractory material, mainly mgo (m.p. 2800ºc), a binder, and a void forming substance for insulating purposes. different oxides from the slag penetrate into these voids and provide low melting-point phases suchasrhodonite (mnsio3) (1290ºc), tephorite (mn2sio4) (1345ºc), merwinite (ca3mgsi2o8) (1575ºc), monticellite (camgsio4) (1490ºc), and enstatite (mgsio3) (...

To produce prostheses through the digital flow, it is essential to transfer correct patient’s interocclusal relationship software program, enabling articulation of virtual models. Therefore, aim this study was carry out a narrative literature review describe and discuss aspects related occlusal record realization, as well its precision accuracy in different clinical situations. Searches for sci...

This study aimed to compare conventional, digital 2D and 3D workflows as possible aesthetic rehabilitation processes for the maxillary anterior area using “open-source” software. For conventional workflow, a diagnostic wax-up was produced by dental technician. Keynote software (version 11.1) used perform analysis smile planning. Measurements were taken technician obtain wax-up. session, plaster...
