Aesthetic Rehabilitation with Ceramic Laminates By the System CAD/CAM- A Case Report

Abstract

The demand for cosmetic treatments has increased considerably in dental offices.Current laboratory techniques associated with a strict clinical protocol satisfy patients restorative and esthetic needs.Thin ceramic laminates are a suitable option to correct shape, symmetry, contour, and size of anterior teeth. Lithium disilicate (LD) ceramic laminates are excellent treatment options for performing aesthetic rehabilitation due to the material's strength and tensile properties. In this case report, ceramic laminates were fabricated using an all-digital workflow. The case describes the steps involved in the clinical protocol to perform a high-performance treatment with the CEREC © CAD /CAM system computeraided design and computer-aided manufacturing, with ceramic laminates.

A clinical evaluation of zirconia reinforced lithium silicate glass-ceramic CAD/CAM onlay: a two-year case report

“…Advances in the adhesive area and in the development of materials with better properties have enabled the implementation of more conservative restorative techniques [10]. Onlay restorations are defined as any partial ceramic restoration that covers at least one cusp [1].…”

“…The CAD software, in turn, identifies the areas that need greater thickness according to the intermaxillary relationships between the digitized upper and lower models [5]. Consequently, restorations made by CAD/CAM technology have shown better structural quality, high accuracy, and efficiency [5,10]. The literature has demonstrated good fracture resistance of ZLS restorations at a thickness of 1mm [6].…”

“…Consequently, these restorations eliminate problems related to the union between layers and have better properties than hand-built restoration restorations using conventional techniques such as firing, pressing, and casting, which tend to incorporate pores and flaws within the material [8,9]. Since CAD is highly accurate in electronic impressions, it reduces costs with consumables materials and eliminates several steps of the traditional process of prosthetic preparation [10]. Thus, CAD/CAM technology opened a new era in restorative dentistry, increasing the use of all-ceramic restorations in a more conservative, fast, predictable, comfortable, and long-lasting way [2,10].…”
