“…In such cases, there is a thicker layer of cement [20]. Composite inlays are becoming more popular, mainly due to their aesthetic value, and have been used in most studies on this area [21]; however, a metal inlay was chosen for the present study to negate the influence of water absorption (associated with composite materials) and clarify the effect of absorption on the stresses occurring at the interface between the cement layer and the tooth tissue (epoxy resin).…”

The successful restoration of teeth requires a good connection between the inlay and natural tissue. A strong bond may improve retention and reinforce tooth structure. The purpose of this study was to evaluate the influence of cement layer thickness on contraction stress generated during photopolymerization, and to determine the changes in stress state of the cement occurring during aging in water (over 84 days). Two cements were used: resin composite cement (NX3) and self-adhesive resin cement (Maxcem Elite Chroma). A cylindrical sample made of CuZn alloy was used to imitate the inlay. The stress state was measured by photoelastic analysis. The contraction stress of the inlay restoration was calculated for cement layer thicknesses of 25 µm, 100 µm, 200 µm, and 400 µm. For both tested materials, the lowest contraction stress was observed for the thinnest layer (25 µm), and this increased with thickness. Following water immersion, a significant reduction in contraction stress was observed due to hygroscopic expansion. Applying a thin layer (approximately 25 µm) of composite and self-adhesive resin cements resulted in high levels of expansion stresses (over −6 MPa) after water aging.

“…Inclusion criteria included (1) patients with tooth fracture or caries below the gingiva, (2) those with sufficient crown height for retention, (3) those with a periodontal pocket size ≤3 mm, (4) those with normal oral mucosa and good hygiene, and (5) those who or whose families signed the informed consent. Exclusion criteria were set as follows: (1) patients with a removable denture as the abutment tooth, (2) those complicated with systemic infectious diseases, (3) those unable to receive regular reexaminations as required, (4) those complicated with severe cardiovascular diseases or poor general conditions, (5) those who received treatment with antibiotics or hormone drugs in the last 4 weeks, (6) those with a history of orthodontic treatment, (7) those complicated with immune system defects, or (8) those complicated with malignant tumors or other serious diseases.…”

“…Polymeric ceramic inlay, a new type of porcelain resin, has been widely used for indirect cosmetic prostheses including onlays, inlays, veneers, and fabricated crowns, which can effectively reduce the amount of tooth preparation, preserve the resistance form of the dental tissues as much as possible, and produce good aesthetic outcomes in contrast with postcore crown or full crown. However, ceramic inlay is retained mainly by adhesives, with relatively high technique sensitivity, and there is still a controversy about which restoration method has better application effects on dental defects in clinic 5,6) . On this basis, the polymeric ceramic inlay and full crown restoration were separately applied to patients with dental defects, and the changes in the severity of pain, inflammatory responses and dental functions were observed in the present study, so as to provide a reference for the selection of clinical treatment protocols.…”

We aimed to compare the effects of polymeric ceramic inlay and full crown restoration on patients with dental defects. A prospective randomized controlled study was conducted, in which 106 patients with dental defects treated in the hospital were selected and divided into an inlay group (n=53, treated with polymeric ceramic inlay) and a full crown group (n=53, treated with full crown restoration) in a randomized controlled manner. The success rate of restoration, dental aesthetics, and adverse events during restoration in the two groups were observed, and the severity of pain (Mohd Sulong pain grade) and the levels of inflammatory factors [interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), IL-6, and IL-8] in the gingival crevicular fluid before restoration and at 3 d after restoration were compared. After wearing the prostheses for 1 year, the success rate of restoration in the inlay group was higher than that of the full crown group (96.23% vs. 83.02%), and the dental aesthetics of the inlay group was better than that of the full crown group (P<0.05). Three days after restoration, the inlay group had lower Mohd Sulong pain grade and levels of IL-1β, TNF-α, IL-6, and IL-8 than those of the full crown group (P<0.05). Compared with full crown restoration, polymeric ceramic inlay can result in a higher success rate of restoration and better aesthetics in treating dental defects, and it can alleviate the pain and inflammation stimulation to patients.

“…Clinical researchers have focused on all-ceramic CAD/CAM restorations with observation of their long-term survival [ 14 , 15 ]. However, the studies of RNC blocks have focused on testing the material’s physical and chemical properties in the laboratory, with little investigation of its clinical performance [ 16 , 17 ].…”

Background We aimed to investigate the clinical effects of resin nanoceramic (RNC) computer-aided design/computer-aided manufacture (CAD/CAM) partial crowns on posterior teeth after root canal treatment over a 3-year period. Material/Methods A total of 132 posterior teeth restored with CAD/CAM partial crowns were placed in 128 patients. The observation group (n=66) was restored with RNC restorations, while the control group received lithium disilicate-based glass ceramic (LDGC) CAD restorations. Using Fédération dentaire internationale (FDI) World Dental Federation clinical criteria, 2 calibrated evaluators examined the performance of the restorations at baseline, 6, 12, 18, 24, and 36 months. The Kaplan-Meier method and the log-rank test were adopted to analyze the survival rate. The influence of potential risk factors on the main pattern of failure was studied by univariate Cox regression analysis (α=0.05). Results At the 3-year followup, the survival rate of the partial crowns was 83.1% in the RNC group, and 93.5% in the LDGC group ( P =0.061). Failures were caused by debonding (66.7%), restoration fracture (26.6%), and tooth fracture (6.7%). No significant differences were found between the 2 materials at 36 months, except for the parameters of “surface luster” ( P =0.002) and “occlusal contour and wear” ( P =0.009). The RNC group was significantly more likely to debond than the LDGC group (hazard ratio=9.22 [1.17,72.74], P =0.01). Conclusions RNC CAD/CAM-fabricated partial crowns are a potential clinical alternative for endodontically treated posterior teeth, with a survival rate of 83.1% at the 3-year followup. The main pattern of failure was debonding, which might be influenced by surface pretreatment of the RNC material.
