Biomimetic Dentistry

Dentistry is constantly evolving, with modern methods replacing older techniques. One of these advanced approaches is Biomimetic Dentistry, which, inspired by the natural structure of teeth, aims to offer treatments with minimal invasiveness and maximum durability.

Unlike traditional methods, which often lead to significant destruction of the tooth structure, this approach strives to preserve as much of the healthy tooth as possible while creating natural and resilient restorations. In this article, we will take a closer look at this method, its differences from other dental approaches, its advantages, and its costs.

 

What is Biomimetic Dentistry?

Biomimetic dentistry is a branch of dentistry that aims to restore the natural structure, function, and beauty of teeth with minimal intervention. Biomimetic dentistry is shaping a brighter future for your smile. This method, inspired by nature, provides restorations that are up to five times more durable and perfectly match the dental tissue, transforming the dental experience. The principles of biomimetic dentistry are based on the following factors:

 

 

• Preserving the natural tooth structure: Unlike invasive methods, this approach only repairs the damaged parts.
• Flexible and durable restorations: The materials used in this method have flexibility similar to that of natural teeth.
• Increased longevity of restorations: Biomimetic restorations are less likely to fracture or separate.
• Reduced need for more complex treatments: In many cases, this method prevents the need for treatments such as crowns or root canals.

The Difference Between Biomimetic Dentistry and Traditional Methods

 

Unlike traditional methods, which typically involve extensive tooth drilling and the replacement of natural tooth structure with artificial materials, biomimetic dentistry aims to minimize damage to the healthy tooth tissue and preserve its natural function. The key differences between biomimetic dentistry and traditional methods include:

 

 

Tooth Destruction

In traditional dental methods, to treat cavities and fractures, a large amount of the tooth structure is removed to make space for restorative materials like amalgam or crowns. This weakens the tooth and increases the likelihood of future fractures.

In contrast, biomimetic dentistry removes only the damaged parts of the tooth and strengthens the tooth structure using advanced materials that closely resemble the physical and mechanical properties of natural teeth.

 

Need for Root Canal Treatment

In traditional methods, due to extensive tooth preparation and the loss of significant tooth structure, the tooth nerve is often exposed to damage, increasing the need for root canal treatment. Biomimetic dentistry, on the other hand, reduces the need for root canal treatment by preserving the original tooth structure and minimizing damage.

 

Longevity of Restorations

Traditional dental restorations, especially those made from amalgam or conventional composites, typically require replacement or repair after a few years. Biomimetic methods, however, use advanced materials and specific bonding techniques to create restorations that last longer and offer greater resistance to chewing pressures.

 

Use of Materials Similar to Natural Teeth

One of the unique features of biomimetic dentistry is the use of materials that closely mimic the composition, strength, and flexibility of natural teeth. In traditional methods, materials like amalgam or hard ceramics are often used, which may differ significantly from the natural tooth tissue and can sometimes lead to cracks in the tooth. In contrast, biomimetic dentistry uses composite resins and bioadhesive materials that provide strength and performance similar to natural teeth, helping to maintain the overall health of the tooth structure.

 

Types of Dental Restorations in Biomimetic Dentistry

Generally, there are two main methods for tooth restoration in biomimetic dentistry, which are chosen based on the extent of damage and the patient's condition.

 

 

Direct Restoration

Direct restoration is one of the common methods in biomimetic dentistry, where the dentist applies restorative materials directly onto the tooth during the same treatment session. This method is more suitable for cases where the tooth decay or damage is limited and superficial. The features of direct restoration are:

• Speed and Efficiency: Since this method is completed in one session, the patient does not require multiple visits.
• Preservation of Tooth Structure: In this method, the healthy enamel of the tooth is minimally shaved, and the natural structure is maintained.
• Cost-Effective: The cost of this type of restoration is generally lower than indirect methods.
• Applicable for Mild to Moderate Cases: Direct restoration is mainly used for superficial to moderate cavities and minor cracks in the tooth.

 

Indirect Restoration

For cases where the damage is more extensive and requires greater strength and precision, the indirect restoration method is used. In this method, an impression of the tooth is taken, and the restoration is fabricated in a laboratory. Then, during a follow-up session, the prepared restoration is placed onto the tooth. The features of indirect restoration are:

• High Precision and Durability: Since the restoration is made in a controlled laboratory environment, this method offers greater accuracy and durability compared to direct restoration.
• Suitable for Extensive Damage: For teeth that are severely damaged or need complete reconstruction, this method is considered a better choice.
• Requires More Treatment Sessions: Due to the steps of impression-taking, fabrication, and placement, this method usually requires at least two treatment sessions.

 

Applications of Biomimetic Dentistry

This method can be used in many dental treatments, including the following:

• Restoration of Tooth Decay: In traditional methods, hard materials like amalgam are used to fill teeth, which over time may lead to cracking. In biomimetic dentistry, flexible composites that are compatible with the tooth structure are used, offering greater durability.
• Treatment of Tooth Fractures: Tooth fractures, especially in front teeth, can significantly impact the appearance of a smile. With biomimetic methods, minor to moderate fractures can be restored in a way that looks natural and provides high strength.
• Prevention of Root Canal Treatment: One of the biggest advantages of this method is the reduced need for root canal treatments. Since the natural structure of the tooth is preserved, the likelihood of inflammation and nerve damage is minimized.
• Smile Aesthetics: This method is also very useful for cosmetic restorations. Because the materials used are fully compatible with natural teeth, the final result will look very natural and beautiful.

 

What Are the Benefits of Biomimetic Dentistry?

Restoring teeth using the biomimetic approach offers numerous benefits due to the preservation of the natural tooth structure and the use of materials similar to enamel:

 

 

Increased Durability and Strength of the Tooth

In traditional methods, a significant amount of healthy tooth structure is often removed to perform dental restorations, which can weaken the tooth. However, in biomimetic dentistry, preserving the original tooth structure is prioritized. By using strong adhesives and advanced composite materials, restorations are created that last longer, reducing the risk of tooth fractures or wear.

 

Reduced Long-Term Treatment Costs

A common challenge in dental treatments is the need for frequent restorations, which can lead to high costs for patients. In biomimetic dentistry, due to the use of conservative techniques and durable materials, the need for repeated treatments is minimized, resulting in long-term savings on dental costs.

 

More Natural Appearance

The materials used in this method closely resemble the color, translucency, and texture of natural tooth enamel. As a result, biomimetic restorations appear very natural, with no noticeable difference from the patient’s natural teeth. This feature greatly enhances patient satisfaction with the appearance of their smile.

 

Reduced Tooth Sensitivity

One of the common problems that many people experience after dental treatments is sensitivity to hot and cold. Biomimetic dentistry helps reduce this sensitivity by preserving the healthy tooth structure and minimizing the need to shave off enamel, thus preventing internal nerve irritation and minimizing tooth sensitivity.

 

Reduced Pain After Treatment

This method uses advanced bioactive adhesives and restorative materials, creating a stronger bond with the tooth structure. This not only increases the longevity of the restoration but also helps reduce pain and discomfort following treatment. As a result, patients typically experience a shorter recovery period.

 

Factors Affecting the Cost of Biomimetic Dentistry

The cost of biomimetic dental treatments is influenced by several factors, with some of the most important ones being:

1. Extent of Damage and Need for Restoration
   The level of decay and damage to the tooth is one of the most significant factors in determining the cost. The more extensive the damage, the more complex the treatment interventions required, and as a result, the higher the treatment cost.
2. Type of Materials Used
   In biomimetic dentistry, advanced and biocompatible materials such as nanohybrid composites, bioactive ceramics, and strong dental adhesives are used. These materials are of high quality, more durable, and better compatible with the natural tooth structure. However, they tend to be more expensive compared to conventional materials used in traditional methods.
3. Experience and Expertise of the Dentist
   Performing biomimetic treatments requires a high level of knowledge, expertise, and skill from the dentist. Dentists who are trained and have more experience in this specialized field generally charge higher treatment fees, but in return, the quality of the treatment is typically higher.
4. Geographic Location of the Clinic
   The cost of dental treatment can also vary based on the clinic's location. In larger cities and areas with a higher cost of living, dental treatment fees are usually higher than in smaller towns.

 

 

Comparing the Cost of Biomimetic Dentistry with Traditional Methods

Although the initial cost of biomimetic treatments may be higher than traditional methods, it can be more cost-effective in the long run. In traditional methods, materials such as metal fillings or non-biocompatible crowns are commonly used, which may fracture, leak, or wear down over time, requiring frequent repairs. In contrast, biomimetic dentistry focuses on preserving the natural tooth structure and using more durable materials, reducing the likelihood of further damage and the need for additional treatments.

 

Conclusion

Biomimetic dentistry is an innovative and effective method for restoring teeth that maximizes the preservation of natural tooth structure, leading to increased durability and a reduced need for more complex treatments. Compared to traditional methods, it offers significant advantages, including reduced sensitivity, a more natural appearance, and higher resistance. Given that this approach requires high skill and the use of advanced materials, choosing a dentist with expertise in this field is crucial.
