Study of Deflections in Maxillary Major Connectors: A Finite Element Analysis
National Center for Biotechnology InformationU. This study investigated the deformation of four major connectors for maxillary Kennedy Class I removable partial dentures.
In these systems, the number of cycles that symbolize period change into 1, B, Inferior border of the major connector is outlined.
Share buttons are a little bit lower. The solid geometry is created through form feature option sweep along guides.
Acceptability of maxillary major connectors in removable partial dentures
The geometry is taken from the radiographic images and drawn in the sketches. Therefore, it is ideally suited for the analysis of bibliographical structure because it can model complex geometric shapes and materials, which are not homogeneous. Model 2—full palatal plate in class I Fig. Basic principles of their selection and design. Open in a separate window.
The choice of connector lies between plate, a bar or a combination of bars, which may cross the palate in various positions. The wax models were cast in a hard aluminum alloy EtialEtibank. Single Palatal Bar Most widely used and yet the least connwctors of all palatal major connectors. Maxillary Major Connectors Six basic types of maxillary major connectors are considered: Free gingival margin Cross abruptly at 90o Relief is used to minimize impingement FigStewart’s. Intimate contact between the connector and the supporting tissue adds much to the support, stability, and retention of the denture.
If the rectangular space is bounded by the lingual bar, the anterior tooth contacts, and the cingula, and the bordering minor connectors are filled in, a linguoplate results Figure A questionnaire was administered to ascertain their reactions to each of the three denture designs. Also, all the patients except one described the denture with the metal bar connector as the least disturbing during normal rest whereas eight majog Questions Metal bar Metal plate Acrylic plate Majlr denture interfered least with speaking?
Major connector is an important component of removable partial connector RPD.
Go to Application Have a question? Most scientists prefer palatal plate major connectors. This component also provides cross-arch stability to help resist displacement by functional stresses.
Linguoplate If the rectangular space is bounded by the lingual bar, the anterior tooth contacts, and the cingula, and the bordering minor connectors are filled in, a linguoplate results Figure Were all of the dentures equally easy to tolerate during normal rest?
The film pairs mm apart were superimposed over each other by special analytic equipment Planicomp C, Carl Zeiss and changed to three-dimensional models.
Finite element methods have been proved to be one of the best methods for research [ 5 ]. Removable partial dentures help in replacing missing teeth and ln tissues to a certain extent. All the patients treated in this study indicated that the dentures were not equally tolerated during normal rest. Model 2—two mesial occlusal rests on the PM I Fig.
5: Major and Minor Connectors
This special point showed the highest deformation in the palatal strap major connector. Connectors should be of minimum bulk and should be positioned so that interference with the tongue during speech and mastication is not encountered.
Type of major connector. There were no microcracks on the surfaces of the U-shaped plate and anteroposterior bar major connectors Fig 4abut there were microcracks in both the palatal plate and palatal strap denture groups Fig 4b. Model 3—class II—anteroposterior palatal strap load application. Fig 4a Anteroposterior bar major connector that has no microcracks in the fluorescence liquid penetrant inspection test.
