in deliverying the framework for partial denture, ( Kennedy I classification)
when you put pressure int the postorir of the framework, the anterior part of the framwork moves alot. what is the problem?
A)is this normal for Class I partial denture?
B) tight the clasp close to the distal area ( I think this is the answer) what you guys think?
C)or adjust the indirect retention. ? I know this is not the answer because indirect retention is used to prevent the prosthesis move toward the tissue.
D) reline it.

which one you thin is the answer.

hi
i think the ans is adjust the indirect retention.......coz the question says whenb we put pressure on the posterior part the anterior part moves a lot ......so that problem can only be corrected with a proper indirect retention......jus my opinion...sry if i am wrong

Indirect retainer is a part of the removable partial denture that stabilizes it by resisting dislodging stress exerted against the denture on the opposite side of the fulcrum line.
I understand that the question being asked is referred to pressure applied on the posterior part in gingival direction and not in occlusal direction. 🙂

hey guys , when they say that (framwork moves ALOT), means that there is an ABNORMAL space between the denture and the soft tissues...whatever you wd do in clasps and retainers to resolve that, it wd overload the patient's teeth, which is undesirable, and worse when he eats .!!! as you know in class 1 & 2 support is obtained by soft tissues, and retention is obtained from teeth by clasps and other retainers..so the answer is to fill this space and reline the denture..that happened to me once with a diabetic patient who was taking long time between appointments.

happy new year for all

i think answer is relining.moves lot under pressure mean not stable .

While it is possible to compress the edentulous areas during the impression stage and obtain an inacurate impression of the area, it is unlikely that this is the source of the problem. There should be no need to reline a newly constructed rpd. Resorption of the edentulous area is possible, however, this usually takes months. Adjusting the db clasp would have no effect on the anterior displacement during the application of occlusal forces on the posterior segment. Since the displacement would be gingivally, the db clasp would be positioned slightly more gingivally and, therefore, ineffective. The db clasp is designed to offset occlusal forces in the anterior segment. In this case, it is more likely that an adjustment needs to be made to the mb clasp that should be present either on the mb of the 1st premolar or the canine depending on the teeth that are still present. Usually the clasp is placed as far anteriorly as possible. As occlusal forces are placed on the distal extention rpd, the clasp on the mb (indirect retainer) will engage in the undercut to stabilize the partial denture.
