This clinical report presents the reconstruction of a maxillary arch with a cement retained implant supported fixed prosthesis using a monolithic zirconia generated by CAD/CAM system on eight osseointegrated implants. The prosthesis was copy milled from an interim prosthesis minimizing occlusal adjustments on the definitive prosthesis at the time of delivery. Monolithic zirconia provides high esthetics and reduces the number of metal alloys used in the oral cavity.

Background: Although surface finishing processes are effective against Streptococcus mutans biofilm, the mechanism of action of saliva with different acidity values ​​has not been studied in detail. This study aims to produce four different all-ceramic materials in a single session with CAD/CAM devices and apply two different surface finishing processes, glazing and polishing, and then determine the retention of Streptococcus mutants on the surfaces of the materials in saliva with varying levels of acidity.

Methods: Zirconia-reinforced lithium silicate (Vita Suprinity, Vita Zahnfabrik, Bad Saöckingen, Germany), monochromatic feldspar (Vitablocs Mark 2, Vita Zahnfabrik, Bad Saöckingen, Germany), leucite glass ceramic (IPS Empress CAD, Ivoclar Vivadent, Liechtenstein), and monolithic zirconia (Incoris TZI (Cerec) Sirona, Germany) were used in the study.

Objective: To assess the clinical, radiographic and patient-reported outcome measures, and the success of screw-retained one-piece monolithic zirconia implant-supported restorations in the posterior region during a 1-year follow-up.

Methods: In a prospective case series, 50 single molar sites in the posterior region of 41 patients with a minimum age of 18 years and sufficient bone volume for placing an implant (≥ 8 mm) and space for an anatomical restoration were included. Following prosthetic-driven digital three-dimensional treatment planning, a tissue-level implant with an internal connection was inserted during a one-stage surgical procedure.

Objective: To assess the effect of chairside adjustment and polishing on the clinical performance of zirconia endocrowns and digitally calculate the opposing enamel wear.

Materials And Methods: A total of 20 participants received zirconia endocrowns on their endodontically treated lower first molars. All endocrowns were fabricated using CAD/CAM technology.

Article Synopsis
  • The study aimed to assess the biomechanical performance of different designs of three-unit implant-supported prostheses using two materials (Zirconia and PEKK) under various loading conditions.
  • Three models were created with different implant placements to analyze three designs: distal cantilever, fixed-fixed, and mesial cantilever, utilizing finite element analysis for stress evaluation.
  • Results indicated that the fixed-fixed design performed best, with PEKK showing lower stress in some areas but higher stress in others compared to Zirconia, highlighting the importance of design and material choice in prosthodontics.
