“…On the other hand, despite extensive materials and technique developments, the chipping of the veneering layer in zirconia-based crowns is still not fully solved. There are many factors that could be associated with chipping fracture of layered zirconia, but residual and transient thermal stresses seem to be the most significant factors, which cannot be clinically evaluated (38). Some studies indicated the importance of the design of the FDPs and postulated this to modulate the risk of veneering chipping, so more teeth that are in block construction and individualized design of the framework according to each clinical has been proposed in an attempt to give good support to the veneering ceramic layer (39,40).…”

Skeletal class II division 1 malocclusion is primarily characterized by maxillary protrusion, mandibular retrusion or a combination of both. Treatment modalities for these patients are different depending on the age and the severity of the case. In adult patients with skeletal class II division 1, where the discrepancy is very severe, orthodontic and orthognathic surgery combined are often necessary to ensure an appropriate treatment, while prosthodontic treatment may be a challenge due to the skeletal discrepancies of the maxilla and the mandible. This clinical report presents a 45-year-old patient with a diagnosis of Angle Class II division 1 malocclusion. After clinical and radiographic observation and consultation with an orthodontist and maxillofacial surgeon, a combination of surgical and orthodontic therapy was proposed. Considering that the patient refused the surgical procedure due to fear, orthodontic therapy was carried out first, which improved the aesthetic and functional characteristics, but did not give results in increasing the vertical dimension of the occlusion. Therefore, further therapy was prosthetic, and was carried out by making all-ceramic maxillary and mandibular fixed dental prostheses; the patient was successfully rehabilitated and the anteroposterior discrepancy between the dental arches was corrected. Combined orthodontic and prosthetic treatment can be a good option in the complex treatment of patients with skeletal class II division 1 malocclusion providing functional rehabilitation of the stomatognathic system and improving facial appearance and the quality of life of the patient.

Introduction. The utilization of ceramics in the field of dentistry has seen a significant rise owing to their esthetic appeal and excellent functional properties. The use of ceramics in the field of dentistry has witnessed a notable surge, driven by their appealing esthetics and exceptional functional attributes. Zirconia, distinguished by its exceptional mechanical strength, plays a pivotal role in the fabrication of posterior crowns and bridges. Among zirconia variants, monolithic zirconia stands out, where the entire restoration is crafted from zirconia material. In parallel, feldspathic porcelain, chosen for its remarkable resemblance to natural tooth enamel, represents another significant ceramic type. This study aims to evaluate the shear bond strength (SBS) between two types of monolithic zirconia with two types of feldspathic porcelain. Methods and Materials. Forty‐four monolithic zirconia veneered discs with feldspathic porcelain were subjected to SBS testing. The dimensions of the discs were 7 mm in diameter and 5 mm in height (3 mm of zirconia and 2 mm of porcelain). Subsequently, the specimens were subjected to a universal testing machine at a speed of 0.5 mm/min until failure occurred. The type of failure was examined using scanning electron microscopy. One‐way analysis of variance (ANOVA), two‐way ANOVA, Fisher’s test, and multiple Tukey comparisons were used as statistical analyses. Results. The highest SBS was achieved by the high‐translucency monolithic zirconia with enamel porcelain group (18.81 ± 3.18 MPa) and the high‐translucency monolithic zirconia with dentin porcelain group (17.89 ± 2.75 MPa), followed by the low‐translucency monolithic zirconia with dentin porcelain group (15.04 ± 2.24 MPa) and the low‐translucency monolithic zirconia with enamel porcelain group (14.33 ± 2.00 MPa), respectively. Additionally, the most common type of failure pattern observed was mixed, followed by adhesive failure. Conclusion. The translucency of the porcelain did not significantly affect SBS, while the type of monolithic zirconia used had a significant impact. Furthermore, there was no discernible relationship between the four groups in terms of the distribution of failure patterns.
