Abstract

Objective

To analyse the bond strength to aged CAD/CAM composites and a polymer-infiltrated ceramic network (PICN) after different surface pretreatments and the use of a universal adhesive or universal primer and universal adhesive.

Methods

Specimens were prepared from CAD/CAM composites (Brilliant Crios, Grandio Blocs, Lava Ultimate, Tetric CAD, Cerasmart270, Katana Avencia, Shofu Block HC) or PICN (Vita Enamic) and artificially aged (5000 cycles, 5–55 °C). The surfaces were left untreated or pretreated by mechanical roughening, aluminium oxide sandblasting, silica coating, or hydrofluoric acid etching (PICN only). The surfaces were further conditioned with a universal adhesive only or a universal primer/universal adhesive (each subgroup n = 12). After application of a composite and further thermal cycling, shear bond strength and failure modes were assessed and statistically analysed by ANOVAs, Weibull statistics, and Chi²-test (p < 0.05).

Results

In CAD/CAM composites, highest bond strength values were obtained for sandblasting (mean of all subgroups: 15.7 ± 4.5 MPa) > silica coating (13.5 ± 4.1 MPa) > mechanical roughening (11.3 ± 4.5 MPa) > no pretreatment (4.1 ± 2.3 MPa). The use of a universal primer led to a significant, albeit small increase of bond strength (11.9 ± 6.0 > 10.4 ± 5.6 MPa). In PICN bond strength was: hydrofluoric acid etching (15.2 ± 4.0 MPa) > silica coating (12.2 ± 4.3 MPa) > sandblasting (11.6 ± 5.3 MPa) > mechanical roughening (10.9 ± 7.2 MPa) > no pretreatment (2.8 ± 2.7 MPa). The application of a universal primer led to a significant increase of bond strength (13.5 ± 6.3 > 7.6 ± 5.0 MPa).

Significance

Adhesion to aged CAD/CAM composites mainly requires adequate micromechanical retention, while PICN additionally requires the use of a universal primer.

与老化的CAD/CAM复合材料和聚合物渗透陶瓷网络的结合强度，使用通用粘合剂，无论是否事先应用通用底漆

目的分析不同表面预处理及通用胶粘剂或通用底漆和通用胶粘剂对老化CAD/CAM复合材料与聚合物渗透陶瓷网（PICN）的粘结强度。方法采用CAD/CAM复合材料（Brilliant Crios, Grandio blocks, Lava Ultimate, Tetric CAD, Cerasmart270, Katana Avencia, Shofu Block HC）或PICN （Vita Enamic）制备标本，并人工老化（5000循环，5-55°C）。表面未经处理或通过机械粗化、氧化铝喷砂、二氧化硅涂层或氢氟酸蚀刻（仅限PICN）进行预处理。表面进一步用通用粘合剂或通用底漆/通用粘合剂进行处理（每个亚组n = 12）。应用复合材料并进一步热循环后，通过方差分析、威布尔统计和chi2检验对剪切粘结强度和破坏模式进行评估和统计分析(p <；0.05)。结果在CAD/CAM复合材料中，喷砂组粘结强度最高（各亚组平均值：15.7±4.5 MPa）；二氧化硅涂层（13.5±4.1 MPa） >；机械粗化（11.3±4.5 MPa）；无预处理（4.1±2.3 MPa）。使用通用底漆可以显著提高粘结强度(11.9±6.0 >；10.4±5.6 MPa)。PICN中的结合强度为：氢氟酸蚀刻（15.2±4.0 MPa） >；硅涂层（12.2±4.3 MPa） >；喷砂（11.6±5.3 MPa） >；机械粗化（10.9±7.2 MPa） >；无预处理（2.8±2.7 MPa）。通用底漆的应用使粘接强度显著提高(13.5±6.3 >；7.6±5.0 MPa)。对老化CAD/CAM复合材料的粘附主要需要足够的微机械保持性，而PICN还需要使用通用底漆。
