05) different between zirconia and IPS specimens for 1- or 0.5-mm thickness. However, fracture loads were significantly higher (P < .001) in specimens supported by enamel, independent of the ceramic material. In aged specimens, the fracture loads of all specimens were significantly (P < .01) higher when supported by enamel; however, in the 0.5-mm groups, zirconia achieved significantly higher breaking loads than IPS when luted to dentin. When 0.5-mm ceramic discs were luted to dentin, zirconia outperformed IPS with respect to breaking loads. When 0.5-mm ceramic discs were luted to dentin, zirconia outperformed IPS with respect to breaking loads. To develop an instrument for the assessment of perception of orofacial appearance and psychologic issues that can affect peoples' judgments. A panel composed of five members (one psychologist, two prosthodontists, one orthodontist, and one final-year dental student) generated 31 items that could draw specific hypothetical dimensions. The questionnaire was self-administered by individuals attending local high schools and university (N = 261; 26.4% men) in the 14- to 28-year age range. Internal consistency, construct validity, responsiveness, and temporal stability were assessed. Factorial analysis and Cronbach's alpha identified four dimensions (self-esteem, perfectionism, body image, and smile appearance concern) that could be best fitted by 17 items. Internal consistency was good (α in the 0.70 to 0.80 range). The dimensions were correlated with existing instruments that measure similar constructs. In responsiveness testing, tooth whitening did not induce changes in perfectionism or body image; however, it did increase self-esteem and decreased esthetic concern (P < .05). The newly created questionnaire is a consistent and reliable short instrument that measures psychologic issues related to the perception of orofacial appearance. The newly created questionnaire is a consistent and reliable short instrument that measures psychologic issues related to the perception of orofacial appearance. To investigate the effect of monolithic zirconia-based occlusal surfaces on signs and symptoms of temporomandibular disorders (TMD) after short-term clinical service. Patients were supplied with multi-unit fixed dental prostheses (FDP) featuring monolithic zirconia-based occlusal surfaces. Prior to prosthetic treatment and 1 year after insertion anamnestic facial pain, pain with palpation of muscles/joints and joint sounds were examined. Of the 50 patients, 43 were re-examined after 1 year. Perceived facial pain was not present, pain with palpation occurred in 2 patients, and TMJ sounds decreased; differences were not statistically significant (P ≥ .058). Single tooth-supported multiunit FDPs featuring monolithic zirconia-based occlusal surfaces did not affect TMD-associated signs and symptoms. Single tooth-supported multiunit FDPs featuring monolithic zirconia-based occlusal surfaces did not affect TMD-associated signs and symptoms.Monolithic zirconia implant-supported restorations connected to titanium bases or titanium inserts are increasing in popularity due to their application in a full digital workflow. These prefabricated abutments are connected to the all-ceramic superstructure by adhesive cementation. Although limited clinical data on the outcomes of this type of restoration are available, a few laboratory studies have shown possible debonding issues. This case report presents a bonding failure of a fixed dental prosthesis supported by titanium bases after short clinical use. A treatment alternative is also proposed using the available digital dental technology. To measure the influence of postpolymerization condition (dry or submerged in water) and time (2, 10, 20, and 40 minutes) on the accuracy of additively manufactured model material. A bar standard tessellation language file was used to manufacture the resin specimens (E-Model Light, EnvisionTEC) using a 3D printer (Vida HD, EnvisionTEC). Two groups were created based on the postpolymerization condition dry (D group) or submerged in water (W group). Each group was divided into four subgroups (D1 to D4 and W1 to W4) depending on the postpolymerizing time (2, 10, 20, and 40 minutes; n = 20 each; N = 160). The specimen dimensions were measured using a low-force digital caliper (Absolute Low Force Caliper Series 573, Mitutoyo). https://www.selleckchem.com/products/bromodeoxyuridine-brdu.html The volume was calculated = × × . Shapiro-Wilk test revealed that the data were not normally distributed. Data were analyzed using Kruskal-Wallis and pairwise Mann-Whitney U tests (α = .05). Significant differences in length, width, height, and volume values were found among the subgroups (P < .0018). In all groups, the width dimension (x-axis) presented the worst accuracy compared to height (z-axis) and length (y-axis) (P < .0018). The D2 and D4 subgroups obtained the closest dimensions to the virtual design; additionally, no significant differences were found between the two subgroups (P < .0018). Dry condition showed higher manufacturing accuracy compared to the water-submerged condition. In the water-submerged subgroups, the highest accuracy was obtained in the W2 and W4 subgroups (P < .0018). Postpolymerization conditions and time influenced the accuracy of the material tested. Dry postpolymerization condition with a time of 10 and 40 minutes obtained the highest accuracy. Postpolymerization conditions and time influenced the accuracy of the material tested. Dry postpolymerization condition with a time of 10 and 40 minutes obtained the highest accuracy.This is a case report of a patient with soft palate muscle weakness that caused difficulties with phonation. A provisional palatal lift prosthesis (PLP) was developed, and the patient underwent simultaneous speech therapy. The elevation level of the palatal lift was subjectively assessed along with nasalance analysis and the Urimal Test of Articulation and Phonation results. The final PLP was applied to improve comfort and efficiency, and the patient continually underwent regular speech therapy. The patient showed satisfactory improvement in speech and pronunciation. PLP development combined with speech therapy can improve the accuracy of pronunciation in patients with palatal incompetence, thereby improving quality of life.
