Study Notes

RPD Delivery and Adjustments

The term "adjustment" has two connotations: adjustment of denture bearing areas and occlusal surface, and patient accommodation to the new prosthesis.

Adjustment of Denture Bearing Areas and Occlusal Surfaces

Adjustment involves adjusting the denture base to the supporting tissues and the occlusion of the RPD to the opposing arch.
Final adjustments include adjustment of the denture base to the supporting tissues and adjustment of the occlusion of the RPD to the opposing arch.

Adjustment of the Denture Base to the Supporting Tissues

A pressure indicating paste (PIP) is used to identify areas that need relief.
The PIP is lightly painted on the denture base and the RPD is pressed onto the tissue surface with finger pressure.
Areas that displace the paste are relieved, and the process is repeated until no areas displace the paste.

Relining and Rebasing a Removable Partial Denture

Rebase: replacing the entire denture base material.
Reline: resurfacing the tissue side of the removable prosthesis with new base material.
Metal framework cannot be rebased or relined, only the acrylic denture base.

Relining

Relining is more common than rebasing in dental practices.
A distal extension RPD requires relining more often than a tooth-supported RPD.
Reasons for relining a tooth-supported RPD include unhygienic conditions, unsightly conditions, and the trapping of debris between the denture base and residual ridge.
Relief is accomplished using a slow speed handpiece, a straight nose cone, and an acrylic bur.

Pressure Indicating Paste (PIP)

Areas frequently displaced by PIP include:
- Mandibular: lingual slope of the mandibular ridge, mylohyoid ridge, retromolar pad, and distobuccal border.
- Maxillary: inside of the buccal flange, border of the denture, and the point of the pterygomaxillary notch.

Occlusal Adjustments

The framework of the removable partial denture should have been tried in to establish the occlusal relationships of the RPD to the opposing dentition.
Articulating paper may be used to identify areas that need adjustment.

Follow-up Services

Patients must understand the need for follow-up services to maintain the RPD.
To gain maximum service from the RPD, patients must avoid careless handling, protect remaining teeth, prevent periodontal damage, and maintain healthy tissue.
