“…A recent in vitro investigation (7) studied the fracture strength of alumina and zirconia abutments restored with ceramic crowns (IPS Empress). Although both resist the values established in the literature as maximum load in the incisal bite (90-370 N), the zirconia abutments results were more than twice than the alumina abutments strength (7). The use of zirconia abutments is well documented in the literature with several case reports of its clinical success (8,9).…”

“…Both materials revealed a resistance able to bear incisal forces documented in the literature. Att et al (3), in a similar study, achieved disrupting results with the study of Yildirim et al (7). They found a similar strength between zirconia and alumina abutments.…”

“…In a recent study, Adatia et al (15) proceeded with an in vitro study to assess the effect of different degrees of zirconia abutments clinical reduction, and their resistance to fracture, submitted to clinical similar conditions. When original zirconia abutments (without clinical reduction) were tested, they fractured in the cervical region, such as stated in other studies (3,7), in the adjacent region to the gold screw and the platform of the implant, for all this the design of the interface implant/ pillar seems to have a main paper in the fracture mode (7,15). The zirconia abutments registered values of strength at least 15% higher than the anterior bite force, and it was checked that the abutments preparation did not affect adversely their resistance to the fracture (15).…”

Objectives: An increasing aesthetic demand within developed populations conducted to the fabrication of metalfree restorations and to a wide use of ceramic materials, due to its excellent characteristics of biocompatibility and aesthetics. With the incessant increase of commercial labels involved in this technological advance, a review is imposed on ceramic abutments, specifically on zirconia. We made a search of articles of peer-reviewed Journals in PubMed/ Medline, crossing the terms "Dental Abutments", "Dental Porcelain" and "Zirconia". The review was divided by subtopics: zirconia physical and mechanical properties, precision fit in the implant-abutment interface, zirconia abutments strength and, finally, bacterial adherence and tissues response. Several studies demonstrate that zirconia abutments offer good results at all the levels but relevant issues need further studies and evaluation. One of the most important is the clinical long term success of zirconia abutments on implants, given that in the literature there are no sufficient in vivo studies that prove it.

“…[4][5][6] The good mechanical properties and biological compatibility of zirconia (zirconium dioxide) have led to its increased use for various dental applications. 7,8 A number of advantages of ceramics over metal abutments have been reported in the literature: less mucosal discoloration, 9 less adhesion of bacteria, 10 very low or no cytotoxicity as measured in vitro human gingival fibroblast, 11 and mucosal attachment to zirconia that is as good as that to titanium, according to an animal study.…”

PURPOSE To determine the effect of the cement type and abutment material on the tensile strength required to dislodge zirconia copings. MATERIALS AND METHODS Two experimental groups of abutments were prepared: (1) titanium abutments (n = 30) and (2) zirconia abutments (n = 30). Sixty zirconia copings (custom designed) were fabricated using 3-dimensional computer-assisted design to have a 6-mm projection above the abutment to accommodate a hole, through which a wire was inserted to attach the zirconia coping to a universal testing machine. Each abutment was placed onto an implant analog embedded in acrylic resin blocks to fit onto the universal testing machine. The zirconia copings were cemented onto the abutments with a provisional luting agent, zinc phosphate (ZP) cement, and adhesive resin cement, and after 5500 thermocycles, a tensile force was applied at a crosshead speed of 0.5 mm/min. The removal force was recorded for each specimen. Two-way analysis of variance (ANOVA) and 1-way ANOVA were used for the statistical analysis (P < 0.05). RESULTS The mean forces necessary to remove the zirconia copings from titanium abutments were 6.52, 83.09, and 251.18 N for temporary cement, ZP cement, and resin cement, respectively. For zirconia abutments, the required forces were 17.82, 116.41, and 248.72 N. CONCLUSIONS The abutment material had no effect on retention, but the cement type affected the retention of the zirconia copings.
