“…Finally, the maximum debonding stress values presented in Table 4 were analyzed statistically. Since both groups had an approximately normal distribution (verified through the Shapiro–Wilk test, Section 2.4 ) and equal variances are assumed (the Levene’s test for equality of variances provided a significance equal to 0.893 for an F value of 0.019), a t -Test of the difference of the means was performed, according to [ 24 ]. In this case, the null hypothesis stated that the means of the maximum normal stress values of the two groups were equal.…”

“…However, the adhesive interfaces have their own issues. Thus, they are prone to microleakage, staining, and secondary decays, as a consequence of inappropriate tooth preparation, veneer fabrication, internal and marginal adaptation of the restoration to dental structure, or of functional and parafunctional forces [ 24 , 39 , 40 ]. Tribst et al [ 41 ], as well as Andermatt et al [ 42 ] studied the adhesive strength of the composite resin bound to both etched enamel and etched ceramic.…”

The Influence of a Novel, Crenelated Design of CAD-CAM Ceramic Veneers on the Debonding Strength

(1) Background: Aesthetic dentistry has become one of the most dynamic fields in modern dental medicine. Ceramic veneers represent the most appropriate prosthetic restorations for smile enhancement, due to their minimal invasiveness and highly natural appearance. For long-term clinical success, accurate design of both tooth preparation and ceramic veneers is of paramount importance. The aims of this in vitro study were to assess the stress in anterior teeth restored with Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) ceramic veneers and compare the resistance to detachment and the fracture of ceramic veneers prepared using two different designs. (2) Methods: Sixteen lithium disilicate ceramic veneers were designed and milled using the CAD-CAM technology and divided into two groups according to the preparations (n = 8): Group 1, conventional (CO), with linear marginal contour and Group 2, crenelated (CR), the latter with our novel (patented) sinusoidal marginal design. All samples were bonded to anterior natural teeth. The mechanical resistance to detachment and fracture was investigated by applying bending forces on the incisal margin of the veneers in order to determine which type of preparation leads to better adhesion. An analytic method was employed, as well, and the results of the two approaches were compared. (3) Results: The mean values of the maximum force recorded at the veneer detachment were 78.82 ± 16.55 N for the CO group and 90.20 ± 29.81 N for the CR group. The relative increase, equal to 14.43%, demonstrated that the novel CR tooth preparation provided higher adhesive joints. In order to determine the stress distribution within the adhesive layer, a finite element analysis (FEA) was performed. The statistical t-test showed that the mean value of the maximum normal stresses is higher for the CR-type preparations. (4) Conclusions: The patented CR veneers represent a practical solution to augment the adhesion and mechanical properties of ceramic veneers. The obtained results demonstrated that CR adhesive joints triggered higher mechanical and adhesive forces, which subsequently led to a higher resistance to detachment and fracture.

“…1 Prior chairside tooth replacement attempts used a variety of points like acrylic denture teeth (with or without lingual wire reinforcement), porcelain denture teeth, and resin composites. 12,13 Utilizing the extracted tooth with the help of Dental adhesive products has an incredible bond strength (14.6-15.8 MPa), 14 allowing dentists to treat patients with less invasive tooth preparation that is highly aesthetic and feels natural to the patient. Even though some studies have revealed that laboratory-made composite materials seem to perform well when compared to conventional materials, the wear resistance of laboratory veneering composites is highly variable.…”

Summary: Losing an anterior tooth could be extremely devastating for the patient and to address the psychological and emotional trauma of the patient, quick replacement is crucial. A contemporary conservative choice is a Fiber-Reinforced composite bridge. The current case report describes the fractured permanent mandibular left lateral incisor which needed to be extracted followed by the replacement of the same natural tooth crown as a pontic using Fiber-reinforced composite (Ribbond). The results were satisfying to the patient, both aesthetically and functionally. Long-term follow-up studies are needed to further evaluate this treatment option in the future. Keywords: tooth, denture design, composite resins

“…The adhesive/dentin bond is a heterogeneous construct—its composition includes the hybrid layer, which ideally integrates adhesive with highly porous collagen fibers. Failure of the adhesive/dentin bond is the critical issue preventing long lasting dental restorations [ 4 , 10 , 71 ]. The weaker link resulting in recurrent decay is the hybrid layer, which integrates adhesive with the highly porous collagen fibers.…”

Overcoming the short lifespan of current dental adhesives remains a significant clinical need. Adhesives rely on formation of the hybrid layer to adhere to dentin and penetrate within collagen fibrils. However, the ability of adhesives to achieve complete enclosure of demineralized collagen fibrils is recognized as currently unattainable. We developed a peptide-based approach enabling collagen intrafibrillar mineralization and tested our hypothesis on a type-I collagen-based platform. Peptide design incorporated collagen-binding and remineralization-mediating properties using the domain structure conservation approach. The structural changes from representative members of different peptide clusters were generated for each functional domain. Common signatures associated with secondary structure features and the related changes in the functional domain were investigated by attenuated total reflectance Fourier-transform infrared (ATR-FTIR) and circular dichroism (CD) spectroscopy, respectively. Assembly and remineralization properties of the peptides on the collagen platforms were studied using atomic force microscopy (AFM). Mechanical properties of the collagen fibrils remineralized by the peptide assemblies was studied using PeakForce-Quantitative Nanomechanics (PF-QNM)-AFM. The engineered peptide was demonstrated to offer a promising route for collagen intrafibrillar remineralization. This approach offers a collagen platform to develop multifunctional strategies that combine different bioactive peptides, polymerizable peptide monomers, and adhesive formulations as steps towards improving the long-term prospects of composite resins.
