But not all titanium is created equal – there are different types of this versatile and strong metal that are used for various purposes. In the world of dentistry, the type of titanium chosen for dental implants can make all the difference in the success and longevity of a patient’s new smile. So, what type of titanium is used for dental implants? Join us as we delve into this fascinating topic and explore the properties and benefits of this remarkable material in creating beautiful and functional new teeth.
Dental implants have become a popular choice for tooth replacement, with titanium being the most commonly used material for implant fixtures. Known for its strength and biocompatibility, titanium has been utilized in the medical and dental field for decades. However, not all titanium is created equal. In this article, we will delve into the different types of titanium that are used for dental implants and their unique properties.
Understanding Titanium for Dental Implants
Titanium is a chemical element with the symbol Ti and atomic number 22. It is a strong, lightweight, corrosion-resistant metal that has been widely used in multiple industries due to its unique characteristics. For dental implants, commercially pure titanium (CP) or titanium alloys are primarily used.
Commercially Pure Titanium (CP)
When we talk about CP titanium, we are referring to a grade of pure unalloyed titanium with a purity level of over 99%. This type of titanium is often used in dental implant fixtures due to its high strength-to-weight ratio and excellent biocompatibility. Additionally, CP titanium is relatively inexpensive compared to other types of titanium.
One of the main advantages of CP titanium is its ability to integrate well with living bone tissue without causing any adverse reactions. This process is called osseointegration and it allows for a secure and long-lasting attachment between the implant fixture and the jawbone. Moreover, CP titanium is resistant to corrosion, resulting in superior long-term stability within the oral environment.
Titanium Alloys
In addition to CP titanium, there are also various types of titanium alloys that are commonly used in dental implants. These alloys are created by combining different elements with pure titanium to enhance specific properties such as strength or corrosion resistance.
Two common types of titanium alloys used in dental implants are Ti-6Al-4V and Ti-6Al-7Nb. The numbers indicate their respective composition ratios of aluminum (Al) and vanadium (V) or niobium (Nb). These alloys have higher mechanical strengths than CP titanium while still maintaining excellent biocompatibility.
Ti-6Al-4V
Ti-6Al-4V is the most commonly used alloy in commercial applications including dental implants. Its high strength makes it suitable for use in load-bearing regions such as implant abutments or prosthetic components like denture bars. However, some concerns have been raised about potential allergies or adverse reactions caused by traces of aluminum or vanadium being released from this alloy into the body.
Ti-6Al-7Nb
On the other hand, Ti-6Al-7Nb has similar properties to Ti-6Al-4V but contains niobium instead of vanadium which makes it more biocompatible due to lower levels of metal ions release into the body. Therefore, this alloy has become increasingly popular as an alternative for those who may have sensitivities to traditional Ti-based alloys.
The Role of Surface Treatment
Apart from selecting an appropriate type of titanium or alloy based on individual factors such as allergies or budget constraints, surface treatment plays a significant role in determining the success rate and longevity of a dental implant.
Titanium surfaces can be treated through various methods including etching (chemical or laser), grit-blasting (using tiny particles under pressure), acid etching (using hydrofluoric acid), or plasma treatment (cool gas plasma sterilization). These treatments alter the surface properties such as roughness and hydrophilicity which can influence initial bone cell adhesion during osseointegration process.
Research studies have shown that certain surface treatments improve cell adhesion and bone formation on an implant’s surface while others may not yield any noticeable difference from untreated surfaces. Hence, selecting an appropriate surface treatment based on implant location and patient-specific factors can significantly impact clinical outcomes.
In summary, selecting an appropriate type of titanium or alloy for dental implants depends on multiple factors such as strength requirements, budget limitations, potential allergies/sensitivities towards certain metals,and patient-specific characteristics like bone quality/density at site/surgery region/location etc..

Titanium and Its Use in Dental Implants
Dental implants have become one of the most popular options for replacing missing teeth. These small metal posts are surgically placed into the jawbone and serve as a strong foundation for replacement teeth such as crowns, bridges, or dentures. While materials like gold and other metals have been used in dental implants in the past, titanium has emerged as the most commonly used material. In fact, over 95% of modern dental implants are made from titanium or titanium alloys. But what type of titanium is used for dental implants? Let’s dive deeper into this topic.
Titanium: The Ideal Material for Dental Implants
Titanium is a chemical element known for its strength, durability, and biocompatibility. It is a lightweight metal that is also highly resistant to corrosion, making it an ideal material for medical and dental applications. It was first discovered in 1791 by William Gregor but was not used commercially until the 1940s when it was applied in military and aerospace industries due to its strength-to-weight ratio.
In the 1960s, Swedish orthopedic surgeon Per-Ingvar Brånemark discovered that titanium could fuse with living bone tissue, a process known as osseointegration. This breakthrough discovery paved the way for titanium’s use in dental implants.
The Different Types of Titanium Used in Dental Implants
There are two main types of titanium used in dental implants: commercially pure (CP) titanium and titanium alloy.
Commercially Pure (CP) Titanium
As its name suggests, CP titanium is pure elemental titanium with no other elements added to it. This type of titanium possesses excellent biocompatibility and osseointegration properties. Its surface also has a special oxide layer that enables it to resist corrosion and allow for better integration with surrounding bone tissue.
However, CP titanium has lower strength compared to titanium alloy, making it prone to fractures or bending during surgery. It may also be prone to scratching on its surface, which can lead to bacterial colonization if not addressed properly.
Titanium Alloy
Titanium alloys are made by combining pure titanium with other metals such as aluminum, vanadium, or nickel. The addition of these elements gives titanium alloy greater strength and durability compared to CP titanium.
One commonly used type of alloy in dental implants is Ti-6Al-4V (titanium combined with 6% aluminum and 4% vanadium). This type of alloy has similar properties to CP titanium but offers better mechanical strength. It also has a lower modulus of elasticity which mimics that of human bone more closely.
How Are Titanium Dental Implants Made?
The process of manufacturing dental implants involves precision engineering techniques to ensure that the final product meets strict standards for quality and safety. Here are the steps involved in producing these tiny yet crucial devices:
Step 1: Designing
Before any physical manufacturing begins, computer-aided design (CAD) software is used to create detailed designs based on the patient’s specific needs. This includes factors such as implant size and shape, location in the mouth, and bone density.
Step 2: Milling or Casting
Once the design is finalized, it is then milled out from either solid blocks of CP or alloyed titanium using precision milling machines or cast using specialized molding techniques.
Step 3: Surface Treatment
After milling or casting, the implant’s surface undergoes various treatments such as acid etching or blasting with small particles. This creates microscopic roughness on the implant’s surface which helps promote osseointegration upon placement inside the jawbone.
Step 4: Thread Cutting
The implant’s screw-like threads are cut into its surface using high precision machines to ensure proper fitment inside the jawbone.
Step 5: Finishing
After all necessary modifications have been made on each individual implant, they undergo thorough polishing processes before being packaged for shipment.
