Non-rigid connector: The wand to allay the stresses on abutment. 0000002552 00000 n Rigid connectors though most commonly used, result in early failure of the prosthesis such as debonding as well as put adverse effects on the abutments when used in the case of pier abutment. Non rigid connector- they are usually used for pier abutments due to differences in physiologic tooth movement and difference in arch position of abutment.

Objective: The aim of the study is to evaluate the stress distribution in tooth supported 5-unit fixed partial denture (FPD) having tooth as pier abutment using rigid and nonrigid connectors respectively, under simultaneous and progressive loading. A non-rigid connector is avoided when the posterior abutment … One such clinical situation is existence of a pier abutment in between two edentulous areas. Therefore, the use of a non-rigid connector as a stress breaker has been advocated to alleviate the situation. 0000000016 00000 n 0000003990 00000 n Curvature of the arch, the faciolingual movement of anterior tooth occurs at a considerable angle to the faciolingual movement of molar tooth. 0000006093 00000 n Garg S, Shukla S. Restoration of arches with pier abutment using non rigid connector. The use of a rigid connector can lead to localization of forces on the pier abutment. rigid connector often faces a scenario of clinical failure as the centre abutment is subjected to fulcrum like forces. These movements can create stresses on the abutments in long-span prosthesis. posterior 5-unit FPD with a pier has demonstrated a fulcrum effect of the pier abutment, while all of them have demonstrated increased stresses on the pier when loaded while bearing a non-rigid connector. There is a conflicting opinion on where to place the non-rigid connector. by using custom made non rigid connector" Author(s): Gaba N, Mattoo K. Abstract. Use of the non-rigid connector is restricted to a short span fixed partial denture replacing one tooth. updates international indexed journal peer reviewed monthly print journal double reviewed refereed & referred international journal journal promoted by indian society for health and advanced research Surveying of the diagnostic cast was done to ensure proper placement of the non-rigid connector … Non-rigid connector placed on the distal aspect of pier seems to reduce potentially excess stress concentration on the pier abutment. 0000111763 00000 n Thus, the design and passive fit of non-rigid connectors is significant to success of a long span fixed partial denture. frequently occurring situation in which a healthy tooth is located in between terminal abutments to support an FPD usually it is a maxillary 2nd premolar in between missing first molar and 1st premolar .

KEYWORDS: Pier abutment, on –rigid connector, reverse orientation of key, key-way INTRODUCTION We are more accustomed to the use of rigid connector in clinical practice since its placement requires minimum technical and laboratory expertise. 0000029704 00000 n Therefore, the use of a non-rigid connector as a stress breaker has been advocated to alleviate the situation. 0000006792 00000 n 0000062172 00000 n 0000021719 00000 n Research paper by Ravikumar Suryakanth RS Akulwar, Ashwin A Kodgi Indexed on: 02 Sep '14 Published on: 02 Sep '14 Published in: Journal of clinical and diagnostic research : JCDR It has contributed a huge number of peer reviewed articles, across a spectrum of medical disciplines, to the medical literature. Adams3 advised placing one non-rigid con-nector at the distal side of the pier, and if desired, adding one more at the distal of the anterior retainer. Introduction The occlusal forces applied to a fixed partial denture are transmitted to the supporting structures through the pontic, connectors, and retainers .

When is an intermediate (pier) abutment used? Gill2 rec-ommended placing non-rigid connectors at one side or both sides of the pier abutment. Non-rigid connector placed on the distal aspect of pier seems to reduce potentially excess stress concentration on the pier abutment. 1. In such situations, non-rigid connectors offer a relatively favourable loading thus ensuring the long term health of the abutment … 0000036649 00000 n Statement of the problem Many partially edentulous situations are present whereby the choice between a removable and a fixed partial denture lies within the delicate balance of a single standing abutment.
