Drawbacks in Removable Partial Dentures

Removable Partial Dentures allow versatility but when used to restore small spans they have the following drawbacks:

1. Problems of retention may take the denture unnecessarily complicated and bulky.
2. A removable denture does not always give the patient the confidence of one that is fixed.
3. There is a risk of accidental swallowing of a small removable partial denture.

Occlusal Rests - Removable Partial Denture


Occlusal Rests and Lingual Rest of Removable Partial Dentures should be placed in well-prepared rest seats with rounded external borders. The thickness of Denture Rest should be about 1.5 mm to provide sufficient durability and rigidity. The occlusal rest should be placed in a region without contact with the opposing tooth. It is sometimes necessary to grind the opposing tooth to remove the contact.

Distal Extension Removable Partial Dentures

According to a photoelastic study of support structures in RPD [1]: The distribution of of tension was influenced by the type of retainer, the length of the saddle and by the form of load application. In relation to the retainer, a more equal distribution of forces between the support structures was seen in the RPI retainer, followed by the T-bar and by the circumferential reatiners. As for the saddle length a more equal distribution of forces between the support structures was observed on the long saddles as the dentures with short saddles induced a greater concentration of tensions on the residual ridge. The best distribution of tensions occurred when the load was uniformly distributed, while the load localized on the last artificial tooth induced greater concentration of tensions on the residual ridges.

Adjusting a Removable Partial Denture Metal Framework

Adjusting a Removable Partial Denture Metal Framework

There should be no clicking sound when a Removable Partial Denture metal framework is being seated inside the patient’s mouth. Clicking sound is a sign of excessive force applied on the abutments. The clasps should engage the abutments passively. There should be no pressure or force to the abutments especially when there’s no dislodging forces applied to the Removable Partial Denture. Below is a simple procedure to adjust a casted upper Removable Partial Denture framework.

Correction fluid is used to check pressure points or areas on the framework.

Removable Partial Denture with Cobalt Chromium Framework with premature contact on the occlusal and cingulum rests.


In Removable Partial Denture one piece casting, it is necessary to check and adjust everything in wax pattern stage before the metal framework is casted. It is difficult to adjust the metal framework without disrupting its fit.
