Analysis of stress on a fixed partial denture with a blade-vent implant abutment

Modeling the Mechanical Behavior of the Jaws and Their Related Structures By Finite Element (Fe) Analysis

“…While the effects of alveolar bone height and different loading regimes on stress distribution in posterior fixed partial dentures (Aydin and Tekkaya, 1992) and cantilever systems (Takahashi et al, 1978;Wright and Yettram, 1979;Awadalla et al, 1992) have been investigated in fixed prosthodontic devices, several studies have modeled stress distribution through removable devices, especially complete denture prosthetics (Aydinlik and Akay, 1980;Maeda and Wood, 1989;Darbar et al, 1993;Kawano et al, 1993). An important study, although lacking direct validation, predicted the timedependent build-up of low stresses within the denture material in combination with relatively high stress concentrations in the underlying simulated bone tissues (Kawano et al, 1993).…”

“…Since bone tissue seems to respond to strains (Huiskes and Hollister, 1993), and strains are induced by stresses in adjacent structures such as dental implants, the advent of implantology brought the proliferation of FE analysis studies related to the effects of stresses created by dental implants on the surrounding bone (Kitoh et al, 1978;Takahashi et al, 1978;Weinstein et al, 1980;Cook et al, 1982a,b;Borchers and Reichart, 1983;Rieger et al, 1989;Siegele and Soltesz, 1989;El Charkawi et al, 1990;Rieger et al, 1990;Van Rossen et al, 1990;Mihalko et al, 1992;CIelland et al, 1991;Meijer et al, 1995 (1997) of changes in bone geometry on implant-derived stress distributions (Widera et al, 1976), a prediction that was corroborated in more recent studies (Borchers and Reichart, 1983;Clelland et al, 1993). These findings, in connection with histomorphometric ones, led to the application of more sophisticated FE analyses which combined the so-called global strain environment induced by implant loading with detailed, micromechanical strain predictions of the implant/bone interface (Ko et al, 1992b).…”

Three‐Dimensional Image Correlation Analyses for Strains Generated by Cement and Screw‐Retained Implant Prostheses

“…A stereolithic resin model (Accudental Inc, Golden, CO, USA) was printed using computed tomography data (Imaging Sciences International, Hatfield, PA, USA) from a patient missing all mandibular molar teeth. The resin (ABS transparent resin, DSM Somos, Elgin, IL, USA) used had an elastic modulus of 2,000 MPa approximating published estimates for cancellous bone (1,507 MPa) 20 . Two 4 × 6 mm implants (Osseospeed, Astra Tech, Mölndal, Sweden) coated with a thin layer of liquid cyanoacrylate (M‐Bond 200; Vishay, Malvern, PA, USA) were placed in the left side of the mandibular model.…”

Simulation der Knochenbelastung durch orthodontische Implantate mit Hilfe der Finite-Elemente-Methode. Simulation of Bone Strain by Orthodontic Implants Using the Finite Element Method

“…Die mechanische Charakterisierung der Sutura palatina erfolgte mit Hilfe des Elastizitätsmoduls (Young's #Modul) und der Querkontraktionszahl (v), wie sie von verschiedenen Autoren verwandt wurden [l, 5,12,14,15,16,19]. Um das FE-Modell so realistisch wie möglich zu gestalten, waren Angaben zur spongiösen und kompakten Knochenstruktur aus dem Gaumenbereich erforderlich.…”
