Deflection and Stress Distribution in Three Different IMZ Abutment Designs
Purpose The purpose of this study was to compare the stress distribution in the resin element and the retaining screw for three different IMZ prosthetic systems: 1) original threaded Intra-Mobile Element (IME); 2) Abutment Complete (ABC); and 3) Intra-Mobile Connector (IMC). This stress distribution...

This stress distribution comparison was then related to variations in deflection of the prosthetic superstructure.Materials and Methods Employing the finite element method, a three-dimensional model simulating a cast gold restoration attached to an osseointegrated IMZ implant fixture was generated for each system. The representation of the implant fixture, the supporting structures, and the external contours of the crown were identical in the three models, while the configuration of the abutment varied to characterize the individual systems. Each model was discretized into axisymmetric finite elements representing the crown, the various implant system components, and supporting structures. A series of harmonic functions was written to define non-axisymmetric loads of 100 N and 500 N evenly distributed over the entire occlusal surface of the crown. Each load was applied individually to the models, first in a vertical direction, and then at a 45° angle to the median plane. Predicted deflection and stress distributions were computed and plotted for each loading condition of each model.Results Deflections measured at the buccal cusp tip ranged from 0.002 mm (100-N load applied vertically to the ABC model) to 0.802 mm (500-N load applied at 45° to the IME model). Maximum effective stresses in the retaining screw ranged from 129 MPa (100-N load applied vertically to the ABC model) to 1,315 MPa (500-N load applied at 45°C to the IMC model). A correlation was observed between the peak stresses in the screw and the deflection of the superstructure.Conclusions Deflections and stress concentrations with the IMC were predicted to be in the same range as with the IME, but much greater than with the ABC. | ||

Predicted deflection and stress distributions were computed and plotted for each loading condition of each model.Results Deflections measured at the buccal cusp tip ranged from 0.002 mm (100-N load applied vertically to the ABC model) to 0.802 mm (500-N load applied at 45° to the IME model). Maximum effective stresses in the retaining screw ranged from 129 MPa (100-N load applied vertically to the ABC model) to 1,315 MPa (500-N load applied at 45°C to the IMC model). A correlation was observed between the peak stresses in the screw and the deflection of the superstructure.Conclusions Deflections and stress concentrations with the IMC were predicted to be in the same range as with the IME, but much greater than with the ABC.</subfield></datafield><datafield tag="533" ind1=" " ind2=" "><subfield code="d">2005</subfield><subfield code="f">Blackwell Publishing Journal Backfiles 1879-2005</subfield><subfield code="7">|2005||||||||||</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">computer simulation</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Holmes, David C.</subfield><subfield code="c">DDS, MS</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Aquilino, Steven A.</subfield><subfield code="c">DDS, MS</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Diaz-Arnold, Ana M.</subfield><subfield code="c">DDS, MS</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Stanford, Clark M.</subfield><subfield code="c">DDS, PhD</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">In</subfield><subfield code="t">Journal of prosthodontics</subfield><subfield code="d">Philadelphia, Pa. : Saunders, 1992</subfield><subfield code="g">6(1997), 2, Seite 0</subfield><subfield code="h">Online-Ressource</subfield><subfield code="w">(DE-627)NLEJ243926049</subfield><subfield code="w">(DE-600)2053077-8</subfield><subfield code="x">1532-849X</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:6</subfield><subfield code="g">year:1997</subfield><subfield code="g">number:2</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">http://dx.doi.org/10.1111/j.1532-849X.1997.tb00076.x</subfield><subfield code="q">text/html</subfield><subfield code="x">Verlag</subfield><subfield code="z">Deutschlandweit zugänglich</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">ZDB-1-DJB</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_NL_ARTICLE</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">6</subfield><subfield code="j">1997</subfield><subfield code="e">2</subfield><subfield code="h">0</subfield></datafield></record></collection>

Deflection and Stress Distribution in Three Different IMZ Abutment Designs |
| abstract |
Purpose The purpose of this study was to compare the stress distribution in the resin element and the retaining screw for three different IMZ prosthetic systems: 1) original threaded Intra-Mobile Element (IME); 2) Abutment Complete (ABC); and 3) Intra-Mobile Connector (IMC). This stress distribution comparison was then related to variations in deflection of the prosthetic superstructure.Materials and Methods Employing the finite element method, a three-dimensional model simulating a cast gold restoration attached to an osseointegrated IMZ implant fixture was generated for each system. The representation of the implant fixture, the supporting structures, and the external contours of the crown were identical in the three models, while the configuration of the abutment varied to characterize the individual systems. Each model was discretized into axisymmetric finite elements representing the crown, the various implant system components, and supporting structures. A series of harmonic functions was written to define non-axisymmetric loads of 100 N and 500 N evenly distributed over the entire occlusal surface of the crown. Each load was applied individually to the models, first in a vertical direction, and then at a 45° angle to the median plane. Predicted deflection and stress distributions were computed and plotted for each loading condition of each model.Results Deflections measured at the buccal cusp tip ranged from 0.002 mm (100-N load applied vertically to the ABC model) to 0.802 mm (500-N load applied at 45° to the IME model). Maximum effective stresses in the retaining screw ranged from 129 MPa (100-N load applied vertically to the ABC model) to 1,315 MPa (500-N load applied at 45°C to the IMC model). A correlation was observed between the peak stresses in the screw and the deflection of the superstructure.Conclusions Deflections and stress concentrations with the IMC were predicted to be in the same range as with the IME, but much greater than with the ABC. |
