In the U.S., it is estimated that approximately 120 million people are missing at least one tooth. Several adverse effects arise from missing teeth, including diabetes, cancer, and coronary issues. Because of this, it is extremely important that edentulous patients receive dental treatment. Treatment for missing teeth can include dentures, partial dentures, implants, and fixed bridges.

There are pros and cons to each treatment option for edentulism. In many cases, removable options are prescribed to accommodate financial issues or physiology issues of the patients. As the problem of edentulism continues to grow and affect a large portion of the population, removable options will continue to be an important modality to consider for treatment.

For a lot of patients, a partial denture offers an acceptable option. They can help to improve mastication, facial appearance, keep teeth from moving, and help with phonetics. In addition, they provide a solution for those patients where financial issues create a barrier to other treatments. The two most commonly prescribed partial dentures are either a cast metal or a flexible metal-free option.

Cast Metal Partial Dentures

The cast metal partial denture is one of the most prescribed partial denture restorations (figure 1). Burbank Dental Lab offers Vitallium 2000 and Vitallium 2000 Plus cast metal partial dentures. These restorations offer superior strength that creates a long-lasting solution to missing teeth. In addition, Vitallium 2000 alloys are fracture-resistant (figure 2).

They can be adjusted in a similar way as gold without becoming deformed and offer a precision fit. While this material offers a high strength that is fracture-resistant, it can be designed as a smaller, lighter frame for added comfort and esthetics.

In addition, Vitallium 2000 partial dentures offer the following benefits:

  • High surface luster
  • Resist plaque buildup
  • Biocompatibility - the Vitallium alloys are beryllium and nickel free
  • Long-standing clinical success
  • Easy to adjust with no deformation
  • Precision fit
  • Extremely comfortable to wear
  • Excellent esthetics

These partials are best prescribed when the case requires rests or attachments to increase stabilization within the arch. The alloy used is a type of Cobalt-chromium. This material is biocompatible and has many benefits.

However, one of the biggest disadvantages is the possible compromise to esthetics due to the metal clasps being placed where they are visible. In addition, these restorations can promote bone loss on the abutment teeth, create adverse tissue reactions, and/or oral galvanism. Therefore, proper design and knowledge are key in creating these restorations.

Flexible Partial Denture

Another great option for partial dentures is Valplast. This is a metal-free flexible partial that offers an alternative to cast partial dentures (figure 3).

The Valplast partial is fabricated using thermoplastic biocompatible nylon. The material is so resilient it is backed by a lifetime warranty protection against breakage of the partial base.

Besides being extremely durable, this option offers superior esthetics that patients expect. Patients are extremely knowledgeable and have high expectations, and this option helps to satisfy even the most discerning of patients. In addition, Valplast comes in a wide variety of tissue colors that enables these restorations to blend seamlessly in the oral cavity without the need for metal clasps.

These appliances provide more than an esthetic solution. They are important for proper mastication and to prevent unwanted tooth movements such as drifting or overeruption. For this appliance to be effective, you must wear it. Valplast offers one of the most comfortable solutions for patients requiring a solution to missing dentition. When an appliance causes discomfort, compliance becomes difficult. The flexibility of Valplast offers functionality and smooth integration within the mouth. Also, this flexible material provides for equal distribution of the forces of mastication, improving the longevity of the partial.

 

Valplast Best Practices

  • The appliance is completely tissue-bearing, requiring no preparation.
  • An alginate impression is recommended
  • For optimal results, a wax try-in is suggested.
  • The appliance should be heated up to body temperature before insertion. This can be accomplished using hot tap water for 60 seconds.
  • Adjustments must be handled with care. This is especially true for adjustments being made to the clasps, as the clasps are critical with regard to retention.
  • To adjust a tight clasp, put it in the hot tap water and bend outward.
  • To adjust a loose clasp, put it in the hot tap water and bend inward.
  • To properly polish the Valplast appliance, we use a bullet-shaped, straight handpiece silicone polisher specifically for acrylic. It should be medium grit.

Should it become necessary to add teeth to a Valplast appliance, it can be done by taking an alginate impression with the appliance in place (figure 4).

The partial should be seated in the impression, and the impression poured immediately. This can then be sent to Burbank Dental Lab to make the changes to the partial.

In addition, if the partial needs to be rebased, it can be done by taking a rubber base impression.

First, ensure proper occlusion by closing the patient's mouth as the material sets.

Next, take an alginate impression, which you should pour immediately. The model should not be separated from the denture.

Valplast partial dentures offer an excellent option for patients seeking a more esthetic option for replacing missing dentition.

Flexible partials provide maximum comfort, are long-lasting, and provide an excellent solution for patients who need an affordable solution to their tooth loss. In addition, it has been in clinical practice for over 60 years, making it a great treatment option.

The key to the success of either a cast partial denture such as Vitallium 2000 or a Valplast flexible partial denture is the proper planning and designing of the appliance. When these are not planned correctly or fabricated correctly, they can cause the patient harm, such as periodontal diseases, issues with plaque, and caries.

By utilizing Burbank Dental Lab's removable team and implementing proper planning and communication, these restorative options help provide patient satisfaction.
