“…The axial alignment of the onlay specimens over the tooth cavity was achieved using a dental inspector apparatus (Ney surveyor TM , Ney-Tech, Bellevue, WA, USA), as seen in Figure 1 E. The onlay inner surfaces were grit-blasted with 50 μm alumina (Al 2 O 3 ) at 2 bar and 10 mm away from the surface for 20 s. Surfaces were ultrasonically rinsed in isopropyl alcohol for 10 min, then in distilled water for 10 min. The inner surfaces of the onlays were conditioned with a silane compound (Ceramic bond TM , VOCO GmbH, Cluxhaven, Germany) over a period of 60 s, then gently oil-free air dried for 5 s following the manufacturer’s instructions [ 2 , 6 ]. Lastly, the inner surfaces were conditioned by a universal adhesive (Futurabond M+ TM , VOCO GmbH, Cluxhaven, Germany) by rubbing with a microbrush for 20 s. An oil-free air was applied onto the adhesive layer for 5 s to remove any solvents [ 2 , 6 ].…”

“…Dental restorations, such as crowns or onlays, can be performed by using chair-side clinical techniques or laboratorial procedures [ 1 , 2 , 3 , 4 ]. The type of dental restoration is dependent on several factors related to the tooth damage, remanent tooth tissues, aesthetic outcomes, and patient-related conditions [ 2 , 5 , 6 ]. For instance, the damage of teeth involving cusps determines the indication for onlay restorations concerning the degree of loss of tooth structures [ 6 , 7 , 8 , 9 ].…”

Purpose: This study aimed to assess the layer thickness and microstructure of traditional resin-matrix cements and flowable resin-matrix composites at dentin and enamel to composite onlay interfaces after cementation on low loading magnitude. Materials and Methods: Twenty teeth were prepared and conditioned with an adhesive system for restoration with resin-matrix composite onlays manufactured by CAD-CAM. On cementation, tooth-to-onlay assemblies were distributed into four groups, including two traditional resin-matrix cements (groups M and B), one flowable resin-matrix composite (group G), and one thermally induced flowable composite (group V). After the cementation procedure, assemblies were cross-sectioned for inspection by optical microscopy at different magnification up to ×1000. Results: The layer thickness of resin-matrix cementation showed the highest mean values at around 405 µm for a traditional resin-matrix cement (group B). The thermally induced flowable resin-matrix composites showed the lowest layer thickness values. The resin-matrix layer thickness revealed statistical differences between traditional resin cement (groups M and B) and flowable resin-matrix composites (groups V and G) (p < 0.05). However, the groups of flowable resin-matrix composites did not reveal statistical differences (p < 0.05). The thickness of the adhesive system layer at around 7 µm and 12 µm was lower at the interfaces with flowable resin-matrix composites when compared to the adhesive layer at resin-matrix cements, which ranged from 12 µm up to 40 µm. Conclusions: The flowable resin-matrix composites showed adequate flowing even though the loading on cementation was performed at low magnitude. Nevertheless, significant variation in thickness of the cementation layer was noticed for flowable resin-matrix composites and traditional resin-matrix cements that can occur in chair-side procedures due to the clinical sensitivity and differences in rheological properties of the materials.

“…The interaction of bone and implant interfaces under an occlusion force is unknown. A study in rabbit femurs showed that the torque removal force of implants ranged from 27 to 59 N at 3-month post-insertion [9]. Titanium oxide layer thickness, micropore configurations and its crystal structures apparently affect bone tissue response.…”

Occlusal Trauma of Implant-Supported Metal-Ceramic Crown: A Case Report

et al. 2021

In this article there is a clinical case of occlusion trauma of implant-supported metal-ceramic crown for prosthetics of central incisor. Its uniqueness is the possibility to save dental implant after acute occlusion impact, which was strong enough to break ceramic facing of fixed denture, but not able to destroy bone and implant components. The occlusion force located at the incisal edge of the crown induced a reverse torque to the implant and did not result in its failure or bone resorption. In a year after repeated fixed prosthetics, the results of clinical examination proved absence of any problem with osseointegration. Literature analysis lets us to suggest, that the phenomenon was caused by protective action of cortical bone around of dental implant. Besides, in the case of natural tooth, the bone is suddenly compressed against the conical root; it transfers occlusal breaking to the supporting periodontal ligament. A dental implant has no periodontal ligament but can have a rough surface that may preclude implant failure.
