Dental Framework

What is Dental Framework?

The Dental Framework is the skeletal portion of prosthesis (usually metal, sometimes ceramic) around which and to which are attached the remaining portions of the prosthesis to produce a finished restoration. For dental prostheses, the framework may be any metal or combination of metals or ceramic material, with various forms including designed slots, incorporated corrective angulation patterns etc. which provide rigidity to a dental prosthesis. Such a framework can be made in whole or made of component parts. Frequently used to anchor a prosthesis to natural teeth (by cementation) or dental implant abutments (by cementation, mechanical undercuts, screws) or both.

Types of Partial Dentures with Framework

Titanium Framework Partial Denture

The framework for this type of partial denture is manufactured via a proprietary CAD/CAM system that precisely mills a three-dimensional titanium framework from a void-free rectangular plate of the metal. This process eliminates labor-intensive steps that can introduce errors into the final appliance. The Titanium framework fits precisely upon delivery without the need to spend precious chairtime making adjustments. The Titanium Framework Partial offers an exact fit and is the most durable of all of our offerings. A titanium framework is difficult to distort and is corrosion resistant, making this type of partial denture stand up well to the intended use and occasional abuse.

Wironium Framework Partial Denture

Small changes in the cobalt-chromium formulation yields an alloy framework that has a high resistance to deformation while, at the same time, being slightly flexible. The clasps resist fracture better than any other product available. These properties allow Wironium frameworks to be incredibly thin while also possessing great strength and durability. The Wironium Framework Partial has a unique retention system of malleable clasps that conform to the tooth contour. The clasps engage correctly at delivery eliminating the need for excessive clasp modification at chairside and metal fatigue. Minor clasp adjustments may be made without the risk of breakage. Try that with any other metal alloy formulations.

Benefits of Partial Denture Framework

Durability and Strength

One of the most significant advantages of Metal Partial Dentures is their durability. The metal framework is designed to withstand the daily wear and tear of chewing and speaking, making them a long-lasting option. This durability means fewer visits to the denture clinic for adjustments and repairs, saving you both time and money in the long run.

Comfort and Aesthetics

Metal Partial Dentures are designed to be comfortable and less intrusive in the mouth. Their thinness and smaller size make them less noticeable, allowing you to smile, eat, and speak with confidence. The metal alloy used is also less likely to cause allergic reactions, making it a suitable option for those with sensitivities to other materials.

Easy Maintenance

Cleaning and maintaining Metal Partial Dentures is relatively straightforward. The smooth metal surface is less likely to harbour bacteria, making it easier to keep clean. Regular cleaning with a denture cleaner and periodic check-ups at your Sunshine Coast denture clinic will keep your Metal Partial Dentures in excellent condition.

Versatility and Customisation

Metal Partial Dentures can be customised to suit your specific needs. Whether you need additional teeth or clasps, these dentures offer a level of versatility that is hard to match. Their adaptability makes them an excellent choice for those looking for a personalised denture solution.

Top 4 Removable Partial Dentures (RPD) Framework Materials

Cast Metal

Traditional cast metal frameworks are the most used. The most popular alloy used for RPD fabrication is cobalt-chromium (CoCr), which offers high strength and excellent biocompatibility.

Titanium

Titanium frameworks are strong, biocompatible, and lightweight, with excellent mechanical properties.

Polyetheretherketone (PEEK)

This is a newer thermoplastic polymer material used for RPD frameworks. The material is biocompatible, lightweight, and has excellent mechanical properties.

Acetal Resin

Acetal resin frameworks are also a popular choice for RPD fabrication. Acetal resin is a thermoplastic material that is biocompatible, lightweight, and easily modified.

Fabrication Procedures of Dental Framework

With traditional casting techniques using precious alloys, cast-on gold cylinders are included in the casting and subsequently the veneering is performed. For manufacturing a titanium or Co-Cr framework different processing techniques are available:

● The framework is cast and then connected to titanium cylinders by e.g. laser welding or bonding with adhesive resin cements.
● Prefabricated titanium framework segments are connected to each other.
● The framework is milled in one piece using the CAD/CAM technology (ComputerAidedDesign/ComputeAidedManufacturing technology).

Using CAD/CAM, a resin framework pattern is fabricated on the master cast and both the framework pattern and the position of the implant abutment replica are then laser-scanned. In the production unit, based on the scan, an identical copy of the resin framework pattern is milled in one piece in titanium, Co-Cr or zirconia. The milled framework is returned to the dental laboratory where the veneering is performed using denture teeth and acrylic resin or ceramic.

Nowadays, CAD/CAM milling of frameworks is the option of choice due due the high precision, passive fit, design flexibility, high material quality and reduced laboratory effort and time. Considering the relatively poor precision of casted frameworks, precious alloys loose acceptance and relevance from both a technical and economic point of view.

What are the Main Steps in Install a Dental Framework?

There are four main steps in denture fabrication, including:

Super Thin Dental Pure Titanium Metal Framework

Measurements: The first step in making a dental framework involves a dentist making a dental imprint on your mouth and checking all the movable tissues in your mouth. This mold will be used to create a plaster model of your mouth so that a properly sized and shaped dental framework can be made. In addition to dental prints, your dentist will also take various measurements of your jaw.

Cast: The next step is to cast a model using a plaster cast and dentures. The plaster cast will be placed in a device called an articulator, which replicates the jawbone. Then, a few facsimile teeth are metal-attached denture models. The metal is then fixed into a gum line and the model is checked for fit. It may be necessary to try on several casts to determine the best fit. The best fit model will be used to create the final tooth framework.

Final Installation: In this step, the dental material of your choice will be settled down and your dentist will make the final dental frame. Starting with the step of removing the tissue, which will affect the whole installation process, the dentist will make sure that he changes as little tissue as possible in your mouth, the dentist will put the part where the frame is attached to your chin to hold it in place.

Adjustments: Once the final dental frame is installed, you will have enough time to adjust to it, or raise any discomfort with your dentist, to change your dental frame. This step can help you get used to the new tooth structure as quickly as possible.

Cast Metal Partial Denture Home Care: Instructions

● Clean your partial denture thoroughly following each meal. Regular toothpaste is too abrasive for the acrylic component of partial denture. Partial denture frameworks are fragile and can bend, so it is important to handle with care.

● Don’t use alcohol, abrasive cleaners, bleaches, whiteners they may scratch the surface of the partial denture and harsh products like bleach which will turn the pink parts of your denture white.

● Do not use boiling water, dishwasher or microwave to clean or soak your partial denture.

● Try to give the oral mucosa a break by leaving partial denture out for 4-6 hours a day. You can soak it in the cleaning solutions at night. The gum tissue needs to rest and to allow normal stimulation and cleansing by the tongue and saliva.

● There are several denture cleaning tablets and solutions are available. There are also less expensive generic denture cleaning products available from stores, which work just as well as more expensive brand names. Read the instructions carefully before using these products.

● If the cleaning solutions are not available, you can use mild hand wash soap detergent with lukewarm water and a denture brush to clean your denture.

● Candida a fungal infection can develops in your mouth and the spore will survive in the crevices of your partial denture. You can use a prescription strength mouth rinse to rinse and soak your partial denture.

● Massaging your gums in the morning and evening with a thumb, finger, or soft bristled toothbrush stimulates blood flow and improves tissue health.

● If you are suffering from dry mouth use Oral balance moisturizing gel can be used to keep tissues moist and can be placed on the partial denture to increase moisture of the gum tissue.

● Avoid scratching your partial dentures with abrasive tooth paste and aggressive brushing; deep scratch lines can harbor plaque and bacteria which cause bad odors.

● Your partial denture has metal clasps that wraps around the tooth to gain retention. Clasps may lose the retention following repeated use. Don’t use pliers to bend clasps. Clasps are fragile and can easily break. Slight finger pressure or pressing against the corner of a table can reactivate the clasp and improve retention.

Comparing the Pros and Cons of Metal VS Flexible Dentures

When choosing between metal partial dentures and flexible partial dentures, it's essential to consider the pros and cons of each option. Both metal partials and flexible partials have their unique advantages and disadvantages that should be taken into account. Let's delve deeper into the key factors to consider:

Durability:
Metal partials are known for their strength and durability, making them a long-lasting solution for replacing missing teeth.
Flexible partials, on the other hand, are less likely to break or shatter if accidentally dropped.

Comfort:
Flexible partials are made from a thermoplastic material that can bend and flex to fit the contours of your mouth, providing a more comfortable and secure fit.
Metal partials may have visible metal clasps, which can cause discomfort for some patients.

Aesthetics:
Flexible partials are designed to blend in with your natural gums and teeth, offering a more natural appearance. The lack of visible metal clasps makes them aesthetically pleasing.
Metal partials may have visible metal clasps, which can be a drawback for individuals prioritizing a seamless and natural-looking smile.

Cost:
Flexible partials are typically more expensive than metal partials.
Additionally, additional teeth need to be added to a flexible partial. In that case, it may require full replacement, resulting in additional costs.

Adjustments:
Flexible partials may require more adjustments over time due to wear and tear, especially if subjected to heavy biting forces.
Metal partials may be easier to adjust and modify as needed.

Ultimately, choosing metal partial and flexible partial dentures depends on your priorities and individual needs. Metal partials may be better if durability and longevity are your primary concerns. However, if comfort and aesthetics are your main priorities, flexible partials may be more suitable.

Ultimate FAQ Guide to Dental Framework

Q: What material is used for framework?

A: Frameworks can be made of zirconia, titanium, precious alloys and Co-Cr base alloys and they can be screw-retained.

Q: How to maintain your dental framework?
