Group B had the highest favorable failure mode. Within the limitations

of this study, the use of a smaller FRC dowel and RRC is recommended rather than enlargement of dowel spaces to accurately fit larger FRC dowels, as the enlargement of dowel space may increase the risk of unfavorable failure. “
“Since the introduction of the endosseous concept to North America in 1982, there have been new permutations of the original ad modum Branemark design to meet the unique GSI-IX solubility dmso demands of treating the edentulous maxilla with an implant restoration. While there is a growing body of clinical evidence to assist the student, faculty, and private practitioner in the algorithms for design selection, confusion persists because of difficulty in assessing the external and internal validity of the relevant studies. The purpose of this article is to review clinician- and patient-mediated factors for implant restoration of the edentulous maxilla in light of the hierarchical level of available evidence, with the aim of elucidating the benefit/risk calculus of various treatment

modalities. “
“To investigate the influence of rehabilitation characteristics in the incidence of peri-implant pathology (P-iP). A total of 1350 patients selleck screening library (270 with P-iP matched for age, gender, and time of follow-up with 1080 controls without P-iP) rehabilitated with dental implants were included. The effect of the independent variables [Implant length in millimeters (IL); implant diameter in millimeters; implant surface (IS); presence of cantilevers; implant:crown ratio (ICR), type of abutment (TA); abutment height; fracture of prosthetic components (FPCs); type of prosthetic reconstruction (TPR); type of material used in the prosthesis (TMUP); loosening of prosthetic components (LPCs); and passive misfit (PM) diagnosed within the previous year] was evaluated

through bivariate analysis (chi-square), with level of significance of 5%. Crude odds ratios (OR) with 95% confidence intervals and the attributable fraction (AF) were calculated for the independent variables individually identified as factors associated with the incidence of peri-implant 上海皓元 pathology. The following variables were identified as risk factors: machined IS (p = 0.015; OR = 1.46), 17° TA (p = 0.000; OR = 3.06), completely edentulous TPR (p = 0.000; OR = 2.49), TMUP (p = 0.000; metal-acrylic OR = 2.29; acrylic OR = 4.90; metal-ceramic OR = 8.43), 1:1 ICR (p = 0.002; OR = 1.54), FPC (p = 0.000; OR = 3.01), LPC (p = 0.000; OR = 4.15), and PM (p = 0.002; OR = 20.36). The attributable fraction rendered the following theoretical potential reductions in the cases if the exposure to the variables was removed: IS (31.5%), TA (67.3%), TMUP (5.4% to 73.3%), ICR (35%), FPC (66.8%), LPC (73.8%), and PM (95.1%).
