In-Vitro Investigation of Fatigue and Fracture Behavior of Transmucosal versus Submerged Bone Level Implants Used in Fixed Prosthesis

Background: The present in vitro study aimed to investigate the fatigue performance of different dental fixtures two emergence profiles. Biological failures are frequently reported because problem canonly be solved by replacing a failing implant with new one. Clinicians addressed minor mechanical failures, such as bending, loosening or fracture screws, abutment, entire prosthesis, simply fixing them. Methods: Transmucosal and submerged bone-level implants underwent strength tests (statical dynamical performance) standardized test: UNI EN ISO 14801:2016. Two types profiles (Premium sub-crestal straight cylindrical-shaped coronal Prama one-piece cylindrical-shape transmucosal convergent neck hyperbolic geometry) were tested, dynamic run failure. Data was analyzed suitable statistical tool. Results: Wöhler curve 0.38 cm Premium group c2, appeared significantly from that c3 (nonparametric one-way ANOVA χ2 = 6; degree freedom 1; probability 0.0043) but not 0.33 c1 0.62; 0.4328). Fatigue configuration 2 one half times better than 3. Group had ultimate failure load (421.6 ± 12.5 N) other settings i.e., (324.5 5.5 c2 (396.3 5.6) reaching almost nonsignificant level. Conclusions: It observed design could provide highest resistance static fracture. On hand, an equicrestal increase endurance.
