A partial denture
A partial denture serves to replace some missing teeth, whether in the upper, lower, or both arches. While enhancing appearance is a common reason for its use, it primarily improves chewing ability. Without support, remaining teeth may shift or erupt, complicating future replacements.
Another key function of a partial denture is to support a full denture. For instance, in cases where there are only a few remaining lower front teeth and a full upper denture, biting on the front teeth can cause the denture to tilt backward. This can impact chewing efficiency, making it challenging to properly chew food without a full set of teeth.
By wearing a partial denture, the conservation of natural teeth is promoted, reducing wear and tear as chewing forces are more evenly distributed. This can have a significant impact on preserving the remaining natural teeth and minimizing their deterioration over time.
What are partial dentures made from?
Acrylic
Acrylic partial dentures are often recommended when there is uncertainty about remaining teeth or significant tooth loss due to their affordability and easy repair, realignment, or addition of teeth. Stainless steel wires are used as clasps for retention.
Valplast
Valplast partial dentures, crafted from a thermoplastic material, offer a unique solution for tooth replacement. Their flexibility and translucency eliminate the need for metal retainers, relying instead on the base’s flexibility to secure the denture in place.
Cast Metal (Chrome)
Cast metal partial dentures present a sleeker and more compact option in the mouth compared to other alternatives, providing exceptional strength, stability, and support for remaining teeth. With their rigid frame, these dentures can transfer bite forces to the remaining teeth through metal rests on the occlusal surface, rather than relying solely on gum support.
The design versatility of cast metal partials offers numerous options to suit individual needs. Retention methods can vary, including cast metal retainers or tooth-colored resin. While repair, realignment, or addition of lost teeth may be possible, it’s essential to consult with your dental prosthetist, as such procedures may require laser welding.
Partial Denture Process
Creating partial dentures follows a similar process to full dentures but involves additional steps to accommodate the presence of natural teeth. Here’s an overview of the process:
Initial Consultation & Examination
As with full dentures, the process starts with a consultation where the dentist examines the mouth, gums, and remaining teeth. The patient’s needs, preferences, and expectations regarding partial dentures are discussed.
Impressions
Impressions (molds) of the patient’s mouth are taken to capture the shape of the gums, any remaining teeth, and the surrounding oral structures. These impressions serve as the foundation for creating the partial denture.
Fabrication of Framework
Unlike full dentures, partial dentures require a framework to attach to the natural teeth. This framework can be made of metal or a flexible material. It is custom-designed to fit snugly against the gums and around the remaining teeth.
Trial Fitting of Framework
Once the framework is fabricated, the patient returns for a trial fitting. The prosthetist ensures that the framework fits properly and securely against the gums and around the natural teeth. Adjustments are made as needed for comfort and fit.
Addition of Artificial Teeth
Artificial teeth are selected to match the color, shape, and size of the patient’s natural teeth. These teeth are attached to the framework using a resin material. The prosthetist ensures proper alignment and aesthetics.
Final Fitting & Adjustment
The patient undergoes a final fitting to ensure that the partial denture fits comfortably and functions properly. The prosthetist makes any necessary adjustments to the bite and alignment to optimize comfort and functionality.
