Acrylic resins are composite materials commonly used in dentistry to restore damaged or decayed teeth.
These materials are known for their bonding properties to tooth structure and also for their aesthetic properties.
This article will discuss in detail acrylic resins, their properties, how they are used in dentistry and the advantages and disadvantages of these materials.
In dentistry, acrylic resins are used to repair and restore damaged or decayed teeth. These materials are composites, i.e. they consist of several components, and are known for their adhesion properties to tooth structure and also for their aesthetic properties. In general, acrylic resins are less invasive than other methods of restoring teeth, such as amalgam fillings, and offer a safer and more aesthetic option for patients.
Acrylic resins are composite materials containing a mixture of quartz or glass particles that are mixed with a polymer matrix. These materials are known for their adhesion properties to tooth structure, as the polymer matrix contains monomers that attach to tooth enamel and dentin.
This makes acrylic resins a good option for restoring damaged or decayed teeth.
Another important property of acrylic resins is that they are translucent or opaque, which means they can be adjusted to match the natural color of the teeth. This makes acrylic resins an aesthetic option for patients, as they can be used to repair front or visible teeth.
Advantages and disadvantages
Advantages of acrylic resins in dentistry include their adhesion properties to tooth structure, aesthetic properties, less invasive and safer use than other tooth restoration methods, and the fact that they do not contain metals, making them a better option for people allergic to metals.
However, there are also some disadvantages of acrylic resins. They can be more brittle than other tooth restoration materials, such as ceramic or metal. In addition, acrylic resins may be more susceptible to discoloration and damage when exposed to substances such as coffee, tobacco or red wine.
Also, the life span of acrylic resins may be shorter than other tooth restoration materials, which means that fillings or tooth restorations may need to be replaced more frequently.
Dental materials used in dentistry are varied, with different compositions, depending on the therapy being sought. However, they can also cause adverse reactions when they come into contact with mucous membranes.
In recent decades, more and more materials have appeared on the market which are clearly better than their precursors, so that preventive and restorative therapies can be carried out both to the patient’s satisfaction, who will be particularly pleased with the aesthetics of the material, and to the doctor’s satisfaction, who will remove the problem and restore balance to the dental arches.
Acrylic resins have long been used in denture technology. They are used to make denture bases, artificial teeth or temporary dentures. However, these materials cause adverse reactions in a
large number of patients. Over time, new types of acrylic resins or polymers have been developed that have favorable characteristics and are compatible with the tissues to which they are added.
Use in dentistry
Acrylic resins are used in dentistry for a variety of procedures such as fillings and restorations of teeth. They can be used to repair decayed teeth, replace old fillings or repair cracks or fissures in teeth.
The use of acrylic resins in dentistry is generally less invasive than other methods of restoring teeth, such as amalgam fillings. This is because acrylic resins can be bonded to existing tooth structure, which reduces the amount of healthy tooth tissue that needs to be removed to install an amalgam filling.
In addition, acrylic resins are safer than other tooth restoration materials such as amalgam, which contains the toxic element mercury. Acrylic resins also contain no metals, making them a better option for people who are allergic to metals.
Indications for self-curing and heat-curing resins are varied and include:
Partial or full denture base
Extended dentures often need to replace missing soft tissues as well, not just teeth. On the other hand, the acrylic component has to ensure that the dentures are field-retained, so that they aggregate over an extensive area of soft tissue.
Repairing dentures – over time, due to overuse, dentures can change or break. If the damage does not require the dentures to be replaced, they can be relined or capped, which is done by the dental technician. Old denture wearers may also experience changes in the morphology of the supporting tissues, so that previous dentures no longer fit intimately to the tissues to which they are attached. The latter situation also requires optimization of the denture base.
Often, for mainly financial reasons, patients opt for artificial teeth made of acrylic resins. They do not have the strength and aesthetics of porcelain, but they are a cheap option for prosthetics and are more cost-effective.
Whether they are intended for patients who need changes in occlusal relationships, those who suffer from bruxism or those who need to protect their veneers, mouthguards have a variety of indications and are becoming increasingly important in dentistry.
Mobile orthodontic appliances
Children are often recommended treatment based on removable braces to correct vicious habits, and this is also a preliminary step to fixed orthodontic appliance treatment. These movable appliances are made of acrylic resins that have a variety of shapes and colors, and are very appealing to young children.
Acrylic resins are also successfully used in partial dentures. Often, if the loss of teeth is not treated early, the teeth adjacent to the edentulous gaps will be altered and the underlying soft tissues will become resorptive, which only makes the subsequent stages of treatment more difficult.
Partial dentures maintain the functional interarch relationships.
Acrylic resins continue to be widely used because of a number of advantages, both economic and aesthetically acceptable.

However, there are also some disadvantages of acrylic resins, such as brittleness and susceptibility to discoloration. It is important for patients to discuss available tooth restoration options with their dentist and consider the pros and cons of each option before making an informed decision.
