Stress analysis of effect of non rigid connectors on fixed partial dentures with pier abutments. [6] Gill (1952) recommended placing non rigid connector at one There are two kinds of connectors, either a rigid (locked) connector or a non-rigid connector (that works like a hinge). CONNECTORS IN FPD. The movement in a non-rigid connector is enough to prevent the transfer of stress from segment being loaded to the rest of the FPD. If rigid connector is given in a prosthesis with pier abutment, the pier abutment may act as a fulcrum. The soldered connectors are made by fusion of intermediate metal alloy to the previously made castings. By constructing bridges with a non-rigid connector, this stress can be decreased. 28-1 Rigid connectors: A three-unit partial fixed dental prosthesis (FDP) replacing the maxillary second premolar. Routine oral prophylactic procedures were carried out.

Orientation jaw relation was recorded using a Face bow (Hanau Spring Bow™) and the primary casts were mounted on a Hanau™ semi-adjustable articulator, in centric occlusion (by Face bow transfer and wax interocclusal record). This factor plays an important role in the potential for failure in long-span FPD. © International Journal of Health & Allied Sciences | Published by Wolters Kluwer -, Long-standing abutment (pier abutment) with edentulous spaces on either side that allow physiological tooth movement and relieve stress, When it is impossible to prepare two abutments with a common path for the placement, When prognosis of an abutment is uncertain; in such cases if the abutment fails only a portion of FPD needs to be remade, In the mandibular arch, with an FPD consisting of anterior and posterior segments, a non-rigid connector is indicated, as the mandible flexes mediolaterally during the opening and closing strokes. google_ad_width = 160; google_ad_type = "text_image"; Non-Rigid Connector for Managing Pier Abutment in FPD: A Case Report. There is a difference in opinion on where to place the non-rigid connector incase of pier abutment. Nonrigid connectors for fixed partial dentures. … In 1973, Rochette 11 first published on a wing-like bridge, which had perforations in the wings that were then bonded to replace a missing tooth. The conventional use of a nonrigid connector (NRC) aids in compensating for the difference in the resistance and retention form between the abutments. google_color_border = "FFFFFF"; google_color_url = "000000"; Contemp Clin Dent. 1 Department of Prosthodontics and Oral Implantology, Shree Bankey Bihari Dental College and Research Centre, Ghaziabad, India2 Department of Prosthodontics and Oral Implantology, Dental College, Azamgarh, Uttar Pradesh, India3 Department of Conservative Dentistry and Endodontics, IDST Dental College, Modinagar, Ghaziabad, India4 Department of Oral Pathology, Swami Devi Dyal Hospital and Dental College, Panchkula, Haryana, India, Correspondence Address:Prince KumarDepartment of Prosthodontics and Oral Implantology, Shree Bankey Bihari Dental College and Research Centre, Masuri, N.

Carl E Misch recommended that in conventional FPD, the ‘male’ google_ad_height = 600; [8] {2006} studied the mechanical interaction of various systems of tooth-implant rigid and non-rigid connections using a non-linear 2D finite element analysis. Three types of FPDS made of type III gold alloy were fabricated: (1) Non-rigid connector at the distal aspect of the second premolar, (2) non-rigid connector at the distal aspect of the canine, and (3) all-rigid connectors. 1). In an FPD requiring the restoration of two missing teeth and where an intermediate pier abutment is present with a single casting (rigid connectors) is not an ideal treatment. Some features of the site may not work correctly. Frictional contact elements were used to simulate realistic interface conditions within the implant system and the non-rigid connector function. Br Dent J 1993;174:405-11. Long-span, fixed-movable, resin-bonded fixed partial dentures: A retrospective, preliminary clinical investigation. The movement in a nonrigid connector is enough to impede the transfer of stress from segment being loaded to the rest of the FPD. This clinical case report discusses the use of an non rigid semi-precision type of connector between distal of 25 and mesial of 26 pontic and 15 and 16 pontic, where 25 and 15 act as a pier abutment. 3rd Edn. The occlusal forces applied to a fixed partial denture (FPD) are transmitted to the supporting structures through the pontic, connectors, and retainers. Keywords: Connector, non-rigid connector… The stress-breaking effect of a non-rigid type of connector used in the FPD utilizing implant and natural abutment is not significantly beneficial to prevent intrusion and may be erroneous for the FPD design. non rigid connector at the distal side of pier, and if desired adding one more at the distal of the anterior retainer [14]. • The connector design determines the success of FDP to a certain extent. Shillingburg HT Jr, Fisher DW. The non-rigid connector act as stress breaker between retainer and pontic instead of usual rigid connector. • Size of connector • Shape of connector www.indiandentalacademy.com 16. Conversely, nonrigid connector functions as a stress breaker between retainer and pontic and have thus been recommended to diminish the forces instead of usual rigid connector. In an FPD requiring the restoration of two missing teeth and where an intermediate pier abutment is present with a single casting (rigid connectors) is not an ideal treatment. The design and passive fit of NRC is critical to the success of a long-span FPD. Akulwar RS, Kodgi A.

To overcome this dilemma, a non-rigid connector may be incorporated on the distal aspect of the middle (pier) abutment. MATERIAL AND METHODS: A 3D FE FPD model was constructed containing one Frialit-2 implant in the mandibular second-molar region splinted to the first and second premolars. The cast connectors are to be properly shaped in wax patterns. Akulwar RS, Kodgi A. J Clin Diagn Res, 8(7):ZD12-3, 20 Jul 2014 Cited by: 2 articles | PMID: 25177650 | … The incorporated design of a non-rigid connector consists of a mortise (female component) prepared within the contours of the retainer and a tenon (male component: 0.7 mm in width) attached to the pontic. The design and passive fit of NRC is critical to the success of a long-span FPD. Conversely, nonrigid connector functions as a stress breaker between retainer and pontic and have thus been recommended to diminish the forces instead of usual rigid connector. Connectors are the part of a FPD that unite the retainers and pontics. {2001} conducted a 15-year clinical evaluation of TISP and found that more bone resorption occurred around rigid than around a non-rigid connector.

When an occlusal force is applied to the pontic, it is delivered to the connector, retainer, and finally to the abutments and the surrounding bone structure by connecting the FPD … If rigid connectors are used in this situation, the pier abutment will act as a fulcrum because of physiologic tooth movement, arch position of the abutment, and the retentive capacity of the retainers. The frequent use of rigid connectors in day to day practice in such situations results in failure and instability of the prosthesis. Resin-Bonded, Etched Partial Dentures.
