Monolithic Ceramics: Effect of Finishing Techniques on Surface Properties, Bacterial Adhesion and Cell Viability

Abstract: Glazed surfaces have a greater roughness and tend to accumulate more biofilm. Polished surfaces have higher SFE; however, they are temporarily cytotoxic.

“…Thus, it is suggested that there will be no fracture occurrence during occlusion. These results may be supported by similar findings in the literature for such materials [7,8,41] For posterior monolithic crowns, different classes of materials may be used such as: acrylic resin generally used for temporary prosthesis; Polyetheretherketone (PEEK) polymer is an alternative resilient material [42], a hybrid ceramic that emerged with the objective of associating the composite resin and feldspathic ceramic qualities; zirconia reinforced lithium silicate, a material structurally similar to lithium disilicate reinforced with zirconia particles [22,43,44]; lithium disilicate [45]; noble metal alloys; yttria-tetragonal zirconia polycrystal (YTZP); and alumina-based ceramics are some possible treatment examples to be found in an oral environment. The higher Table 2 -Tensile strength of the materials simulated in this study, stress peak, average stress, stress concentration ratio and failure risks for crown and cementing line.…”

“…After the implants’ osseointegration period, second stage surgery requires remodelling the marginal gingival tissues (mainly keratinocytes and fibroblasts) around transgingival abutments [ 1 ]. Correct remodelling is essential for direct cellular contact at the level of the implant-abutment interface, which results in a correct mucosal seal [ 2 ], avoids apical migration of the junctional epithelium and bone resorption [ 3 ], and reduces bacterial adhesion on the surface [ 4 , 5 ].…”

“…While much information is available on bacterial colonization of dental ceramic materials (Al‐Ahmad et al, 2010; van Brakel et al, 2011; Do Nascimento et al, 2013; Egawa, Miura, Kato, Saito, & Yoshinari, 2013; Hahnel et al, 2009; Lee et al, 2011; de Oliveira et al, 2012; Rosentritt et al, 2009; Sardin, Morrier, Benay, & Barsotti, 2004; Scotti et al, 2007; Viitaniemi, Abdulmajeed, Sulaiman, Soderling, & Narhi, 2017; Yamane et al, 2013), less is known about fungal adherence to zirconia surfaces (Burgers et al, 2010; Dal Piva et al, 2018; do Nascimento, Pita, Pedrazzi, de Albuquerque Junior, & Ribeiro, 2013; Ehrman et al, 2006; Li et al, 2012). This in vitro study intended to characterize the surface properties such as roughness and surface‐free energy of glazed and polished monolithic yttria‐stabilized zirconia (Y‐TZ P ) polycrystal ceramics and to evaluate the ability of C. albicans and salivary bacteria, Staphylococcus epidermidis, mixed with C. albicans , respectively, to adhere to these substrata.…”
