“…The emergence of these new impression materials enabled a reduction in working time and greater fidelity in the reproduction of details [2]. Since World War II, irreversible hydrocolloids, also called alginate, have been considered the most widely used impression materials in dentistry today, the material of choice for obtaining both study models, in common plaster, type III or stone, and working models, in stone and/or special plaster, total or partial dentate [3]. The main limitation of irreversible hydrocolloids is the volumetric change that the mold presents after being removed from the mouth.…”

Knowing the properties and clinical indications of each material ensures that the dental surgeon can use techniques that guarantee better results for dental prostheses. This study aims to evaluate the dimensional stability of an irreversible hydrocolloid modified by the addition of silicone by condensation. During this evaluated the dimensional distortion of irreversible hydrocolloids according to conditioning time, for four commercial brands, being: Avagel (Dentsply), Hydrogum 5 (Zhermack Spa) and Jeltrate Plus (Dentsply) and Avagel plus Condensation Silicone (Zetaplus [Zhermach]). They were placed in a container with 100% humidity, and the following requirements were evaluated: weight, height, and length of the three groups during the following times: immediately, 24 hours, 48 hours, 72 hours, and 120 hours. All materials evaluated showed adequate dimensional stability within the initial 72 hours. The addition of condensation silicone to the irreversible hydrocolloid mixture did not improve the dimensional stability of the material.

In the past the porcelain building technique was as follows: applying the opaque, building the dentin, layering the enamel and adding the translucent material [1]. But when one talks about dental restorations the only role model to think of is the corresponding natural tooth. The demands of today’s dentists and patients have spurred the authors to seek new ceramic systems [2]. A bioesthetic restoration is only possible when the dental technician bases its build-up technique on precise observations of the natural teeth in order to create the most exact copy possible [3]. The case study here was to try and achieve a high level of esthetic restoration in the posterior area using a complex build-up technique and compare the results with the natural teeth. We have granted sufficient time to analyze the layering of the dentition enamel and translucency and tried to correctly match the surface texture. The technician has focused his attention especially on the occlusal surface because of its morphologic complexity.The conclusion is that a high level of esthetic restoration can be obtained with a very good color match if instructions are followed and close attention to details is being paid. The abrasion and wear over time causes the transparent layer covering the dentin to diminish and easily trick an inexperienced eye. Surface characterization using whitish opaque enamel for the cusp ridges, edges and grooves and the use of individually stained opaque on the metal frame for the natural color impression effect coming from the inside are efficient solutions for achieving close to nature esthetics.
