Currently, there are many options to improve the teeth aesthetic and function, and the experts are looking for new materials to offer the best results to the patients every day (please follow the link to read on Dentist Consultation). The resins and removable partial dentures are one of the most common methods to fill dental cavities and treat the partial edentulism.
Through the years, the experts have used many materials, and combinations of them, to improve the resistance and flexibility of the prosthetic material. Although the acrylic has been used since 1936, the experts have improved this material, and it is considered among the best options to create dental resins and removable partial dentures nowadays.
What are the Acrylic/Acetal Dentures?
The Acrylic/Acetal dentures (also called poly-methylmethacrylate or PMMA and polyoxymethylene or POM) are defined by the experts of the University of Medicine and Pharmacy Timisoara as a synthetically obtained material that can be modelled or injected in many ways to fill dental cavities and other abnormal spaces, or to create dental replacements.
How are the Acrylic/Acetal Dentures created?
To create the acrylic/acetal dentures, the specialists can use the material in two forms, as prepackaged cartridges or in a granular form that will be manipulated to be used as an injectable material.
The thermoplastic grains of acrylic/acetal are heated (it melts at temperatures between 200 and 250°) to plasticize the resin and later fill the mold with the form that is needed (the acrylic/acetal material is injected under pressure).
Finally, the acrylic/acetal dentures are combined with metal-free ackers circular clasps, which act as support and help to stabilize the dental prosthesis in its place when the patient puts it on.
Why must I use an acrylic/acetal denture?
The main indications of acrylic/acetal dentures are very variable. They can be used in young patients that can't use fixed prosthesis, to maintain the space of a recent extraction while the definite treatment is completed, in elderly patients who can't undergo lengthy procedures, as an oral tissue conditioner, as a night-guard or mouth protective device to correct or control undesirable oral habits, as a splint for surgical correction, among others.
What are the advantages of using Acrylic/Acetal Dentures?
One of the main advantages of using acrylic/acetal dentures is the fact that it has both excellent short-term mechanical properties and a great long-term stability. Likewise, acrylic/acetal is considered a very strong and resistant material that is able to resist the normal wear, abrasion and fracturing.
Likewise, as this material is so flexible, it is able to accommodate into the patient’s mouth (even in the most complicated cases) to provide an excellent stability while used. The acrylic/acetal is also considered an ideal material to create a lot of dental prostheses and parts of them, including the pre-formed clasps for partial dentures, provisional bridges, partial denture frameworks, stress-absorbing components of the dental implant systems, single pressed unilateral partial dentures, orthodontic appliances, artificial teeth for removable dentures, among others.
Another important advantage of acrylic/acetal is the great biocompatibility of this material, which makes it an excellent material to be used in the mouth and teeth without experiencing adverse reactions (it is non-allergic and non-toxic). Finally, the dental devices made with acrylic/acetal are very comfortable for the patient, so he/she can use them without any problems.
What are the disadvantages of using Acrylic/Acetal dentures?
The main disadvantage of using acrylic/acetal dentures is that this material doesn't have the same natural translucency of teeth, so some experts consider that the final appearance of the smile could be better by using other materials. However, acrylic/acetal is available in 16 different colors, so the patient and the dentist will choose the more similar to the patient’s teeth and gums to obtain the most natural result with this material.
Another disadvantage of using acrylic/acetal dentures is that using this material can be more expensive than using other materials to create the same product.
How much do Acrylic/Acetal Dentures cost?
The cost of acrylic/acetal dentures will vary according to the procedure it will be used for (as a filling, to create a dental replacement or as a part of prosthesis), the number of teeth that will be treated, the patient’s general mouth health, the need of additional dental treatments, the patient’s desires and needs, among others. The mouth of each patient being different, the cost from one patient from another might change as well.
