Summary: The study evaluated the peri-implant tissue changes and esthetic outcomes of cemented and screw-retained crowns of single-tooth implants in the esthetic zone using zirconia abutments. The results showed that the connection system had no influence on peri-implant parameters and esthetics evaluation for medium-term periods (3 and 4 years).

Summary: This systematic review investigated the clinical outcomes of frameworks made of different materials in patients with implant-supported full-arch prostheses. The included studies reported high implant and prosthetic cumulative survival rates. Various materials and fabrication techniques provide more options for full-arch implant-supported rehabilitations.

Summary: The objective of this study was to compare monolithic hybrid abutment crowns (screw-retained) versus monolithic hybrid abutments with adhesively cemented monolithic single-tooth crowns for implant-borne restorations. Twenty subjects were randomly assigned to receive either cement-retained or screw-retained monolithic restorations. The follow-up period was 36 months, and the results showed no significant difference between the two treatment options in terms of patient satisfaction and restoration outcomes.

Summary: Fabrication inaccuracies can compromise the fit of large-span monolithic zirconia restorations. Even with optimal milling and sintering procedures, horizontal forces caused by misfit cannot be avoided. However, the fit of full-arch restorations made from monolithic zirconia might be clinically acceptable due to the natural tooth mobility.

Summary: This study updated an existing systematic review on the clinical performance of full-arch implant-supported monolithic zirconia fixed dental prostheses. The research found that all 17 included studies reported satisfactory clinical and aesthetic outcomes, with low technical complication rates and high survival rates.

Summary: Through analyzing 13 studies, results showed that the survival rate of fixed mandibular 3-implant retained prostheses was 95.43%, with an average prosthesis survival rate of 89.66% and a mean marginal bone loss of 1.09mm. The study suggests that the implant and prosthetic survival rates of this type of prosthesis are similar to those of full-arch mandibular prostheses retained by four or more implants. Further research is needed to explore the topic.

Summary: This retrospective case series evaluated the short-term clinical advantages and limitations of full-arch implant-supported restorations made of monolithic zirconia suprastructures passively luted to titanium bar infrastructures. The study reported a 100% prosthetic survival rate with no implant failures or serviceable prosthetic complications. While two cases showed minor fracture lines in the zirconia suprastructures, no intervention was required. Long-term clinical studies are needed to confirm these outcomes.

Summary: This study aimed to evaluate the survival rate, marginal bone levels, and full arch prosthetic success of short implants in severely resorbed and edentulous mandibles. A systematic review of three relevant studies found short-term dental implant survival rates ranging from 94.2% to 97.4% with a five-year follow-up, and prosthetic success rates around 62% during the same follow-up. The mean marginal bone level values of the affected short implants ranged from 0.2 mm to 0.6 mm. It was concluded that short dental implants positioned with precision as a full-arch fixed support are a valid therapeutic choice for medium-long-term rehabilitation of severe edentulous mandibular atrophy.

Summary: This study characterized epoxy replicas of cemented zirconia crowns and found surface damage on the occlusal surfaces of posterior teeth, significant variability in surface roughness, and not all anterior teeth following the golden proportion concept. The study design provides a framework for using replicas to identify early patterns or features that may lead to fracture and analyze morphology and symmetry.

Summary: Dental implants have become an established treatment for edentulism, and recent advancements in implant systems and CAD/CAM technologies have transformed prosthodontic practice. This clinical report showcases the interdisciplinary management of a patient with Sjogren's syndrome and terminal dentition, who was rehabilitated using dental implants and zirconia-based prostheses fabricated with CAD/CAM and analog techniques. The successful outcomes highlight the importance of biomaterials and interdisciplinary collaboration in treating complex dental cases.

Summary: This study investigated the fracture resistance of one-piece screw-retained hybrid monolithic zirconia ceramic restorations in different implant angulations. The results showed that tilting the implant up to 15 degrees improved the fracture resistance, but increasing the tilt to 25 degrees did not significantly improve fracture strength. Therefore, one-piece screw-retained hybrid monolithic zirconia ceramic restorations can be used with acceptable fracture strength in esthetic zones with angulated implants.

Summary: This study assessed the fit of screw-retained milled frameworks on six implants realized from digital impressions through the Sheffield test, finding that digital impressions represent a viable alternative to traditional impressions for the fabrication of implant-supported FDPs.
