چکیده
This in silico study aimed to evaluate the biomechanical behavior of a full-arch implant-supported prosthesis on titanium and zirconia monotype implants. A 3D mandible containing 1.0 mm thick cortical cancellous bone was modeled. Four dental implants (3.3 x 10 mm) were inserted into jaw model each model. The consisted Titanium (Ti-S group) Zirconia Monotype/one-piece (Zr-S group). Fixed prostheses cemented onto implant. models exported analysis software divided meshes composed nodes tetrahedral elements. All materials considered isotropic, elastic, homogeneous. Therefore, all contacts bonded, fixed directions, applying static structural axial load 300 N bottom fossa left mola r teeth. Microstrain von-Mises stress (MPa) adopted as failure criteria. Comparable strain values shown peri-implant for both groups. However, Ti-S group presented lower value (1,155.8 MPa) than Zr-S (1,334.2 MPa). Regarding tissues, 612 µε 254 µε. highest peak observed tissues around implant closer Evaluating implants, it is suggested that greater rigidity implant, concentration internal stre sses less dissipation surrounding tissues. ceramic yttrium-stabilized tetragonal polycrystalline may be viable alternative prostheses.

The maxillary full-arch implant-supported fixed prosthesis represents a challenge due to the structural limitations of the existing premaxillary ridge and maxillary sinus. Prior to initiating implant treatment, it is critical to consider the necessary clinical and laboratory procedures needed to obtain an optimal level of patient and clinician satisfaction. Consideration must be given to establ...

Split-Framework in Mandibular Implant-Supported Prosthesis
During oral rehabilitation of an edentulous patient with an implant-supported prosthesis, mandibular flexure must be considered an important biomechanical factor when planning the metal framework design, especially if implants are installed posterior to the interforaminal region. When an edentulous mandible is restored with a fixed implant-supported prosthesis connected by a fixed full-arch fra...
