The following are the principal objections to use of the U-shaped connechors The fluorescence penetrant liquid inspection test was used to detect the surface microcracks.

The consent of patients as well as the ethical clearance was obtained from the beginning of the study. Because the connector must have sufficient width and bulk to provide rigidity, a linguoplate is commonly used when space is insufficient for a lingual bar. Major and Minor Connectors. With the use of conservative mouth preparations in the form of recontouring ij blockout, a lingual major connector can almost always be used.

5: Major and Minor Connectors

It is that unit of the partial denture to which all other parts are directly or indirectly attached. The data were analyzed using the repeated-measures analysis of variance ANOVADuncan’s multiple range test, the paired t test, and the independent t test.

The need for indirect retention influences the outline of the major connector. Where as in a class III situation the connevtors was taken maximum by the rest and outer part of the anterior and posterior straps because of the situation being mostly teeth supported.


Rppd connectors for maxillary removable partial dentures. By proper use of direct retainers and Placement of the components in the most advantageous position. Removable partial dentures help in replacing missing teeth and the tissues to a certain extent. The palatal plate should be located anterior to the posterior palatal seal area.

All gingival crevices and deep embrasures must be blocked out parallel to the path of placement to avoid gingival irritation and any wedging effect between the teeth. The principle of leverage is connected with this component part. Fifteen consecutive patients attending the prosthetic out-patient clinic of Dental Center, University College Hospital, Ibadan who had never worn dentures were cnnectors into the study. Sublingual bar FigureC.

Eight of the subjects The gingival tissue, on the other hand, must have an unrestricted superficial jn supply to remain healthy.

Acceptability of maxillary major connectors in removable partial dentures

During function like mastication and deglutition the framework of the removable partial denture undergo stress and these stress points deform the denture from its final position.

In studies testing the elastic property of a metal object, biaxial hydraulic systems that simulate chewing are preferred.

Although this design may reduce the possibility of food entrapment, it may not provide adequate rigidity.

This type of major connector easily traps food and is often more objectionable to patients than a linguoplate. Log In or Register to continue. Similarly, all the patients reported that the three maxillary major connectors were not equally easy to tolerate during normal rest.


Do rp substantially alter the natural contour of the lingual surface of the mandibular alveolar ridge or of the palatal vault.

Photographing procedures were carried out both before baseline and after each loading period, and the black-and-white film was developed with Kodak solution for the photogrammetric film process stereophotographs.

Figure The hinge for this continuous labial bar connector is located buccal and distal to the remaining dentition area of tooth Tissue response to such small spaces is better when they are bridged with an apron than when they are left open.

Flexibility allows forces to be concentrated on individual teeth or the edentulous ridge, causing damage to the periodontal support of the teeth, resorption of the bony ridge, and impingement and injury to the soft tissue beneath the major connector. As the results of the photogrammetric and fluorescence penetrant liquid inspection test are congruent, it can be suggested that the results of both parts of this study support each other. But when compared between the two, later showed more deflection than the former.
