During the 15-month follow-up period, the patient’s oral condition and physical appearance improved, and no complications occurred. “
“Ocular disorders occasionally necessitate surgical intervention that may lead to eye defects. The primary objective in restoring and rehabilitating such defects with an ocular prosthesis is to enable patients to cope better with associated psychological stress and to return to their accustomed lifestyle. A series of detailed steps for custom-made ocular prosthesis fabrication using the advantages of digital photography to replace the conventional oil paint and monopoly iris painting technique are presented
in this article. In the present case, a digital photograph of the patient’s iris was captured using a digital camera and manipulated on a computer using graphic Selleckchem GW572016 software to produce a replica of the natural iris. The described technique reduces treatment time, increases simplicity, and permits
the patient’s natural iris to be replicated without the need for iris painting and special artistic skills. “
“Purpose: The aim of this study was to evaluate the fracture strength of experimental hollow and solid design zirconia dowels. Materials and Methods: Three types of dowels (fiber-reinforced composite [FRC], hollow design, and solid design zirconia dowels) were tested in the study (n = 10). A three-point http://www.selleckchem.com/products/c646.html bending method was conducted, and a load was applied until fracture. The values were recorded as Newtons (N) and then converted to megapascals (MPa) according to the diameter of the dowels. Statistical analyses were performed using one-way ANOVA and Tukey HSD tests. The significance was set at p < 0.05. Results: The mean fracture strength of the hollow design
zirconia dowels was significantly higher (960.72 MPa) than solid zirconia dowels (741.78 MPa) and FRC dowels (687.64 MPa) (p < 0.05). Conclusions: The hollow design zirconia dowel seems to have sufficient fracture strength for anterior restorations. This design may be beneficial to access the apical region when retreatment is necessary, without any dowel-removing procedure. "
“The aim of this study was to evaluate the photoelastic fringe patterns around two short-wide implants supporting single crowns with different crown-to-implant (C/I) ratios. External hexagon selleck chemical (EH) cylindrical implants (5 × 7 mm) or Morse Taper (MT) conical implants (5 × 6 mm) were embedded individually into photoelastic resin blocks. Each implant received a single metal-ceramic crown, with a C/I ratio of 1:1 or 2:1 (n = 10). Each set was positioned in a polariscope and submitted to a 0.5 kgf compressive load, applied axially or obliquely (30°). The polariscope images were digitally recorded, and based on isoclinal and isochromatic fringes, the shear stress was calculated at 5 predetermined points around each implant. Data were analyzed by two-way ANOVA (α = 0.05).
