Do you know anything about dental implants?

Dental implants are a miracle of contemporary medicine because they give patients a possibly permanent, functional answer to the issue of missing teeth.

Nevertheless, it is absolutely appropriate to inquire as to the composition of anything you intend to implant in your jaw.

In order for you to be knowledgeable about and confident in your restoration, we're going to go into considerably more detail about the materials utilized in the three parts of dental implants below.

From what material are the three implant parts made?

A dental implant is made up of an abutment, which serves as the connection between the post and the restoration, and a post, or screw, that is inserted into the jaw and fused to the bone providing a stable base.

a crown that resembles the visible portion of a real tooth, often known as a prosthesis or restoration. The "crown" for an implant could be a real crown, a bridge, or dentures.

Here are the materials utilized for each section, keeping that in mind:

What material makes up the implant post?

Implant posts are often made of titanium and zirconium.

Since 1981, titanium has been utilized for dental implants due to its high strength, light weight, longevity, resistance to corrosion, and biocompatibility, which refers to how well it melds with the surrounding gum tissue.

Remember that the "titanium" that is so frequently used in posts is actually a titanium alloy, typically Titanium 6Al-4V ELI Grade 23. In other words, it has a mixture of various metals and about 90% titanium. This is done because alloys may be created that are even more durable and capable of withstanding the stresses that teeth must endure than pure titanium.

But this is also one of the reasons zirconium, or ceramic, is becoming more popular as a post material substitute. Though uncommon, titanium in the mouth may cause some people to develop metal sensitivities.

In addition, aluminum and vanadium are frequently added to titanium alloys as additional metals. It has been discovered that germs around the implant can cause the metal to corrode and that having too much of these metals in the body can be a significant medical problem.

Although research continues to support the use of titanium in implant posts, zirconium is more aesthetically pleasing than titanium because to its white color and is even more corrosion- and plaque-resistant for people who are worried about allergic responses.

Zirconium posts have less flexibility for many dental situations than titanium posts do, and they are more expensive.

What materials are used in the implant abutment?

Abutments are most frequently made of titanium and zirconium, just as implant posts.

Zirconium may be recommended over more conspicuous titanium because the abutment is more likely to be seen in the mouth than the post. In what is known as a hybrid abutment, this can be either fully zirconium or a combination of zirconium exterior (superstructure) and titanium, cast gold or cobalt chrome (also known as UCLA), or surgical grade stainless steel core.

In general, titanium is a good material to use when a patient has to replace a single tooth towards the back (posterior) of the mouth, which is the most frequent need for dental implants, or if they have thick gums and a low lip line, which can help hide the metal.

Custom-made, shaded zirconia abutments are ideal when the replacement tooth is in the front (anterior) of the mouth.

There is one more abutment substance worth addressing. A recently developed thermoplastic polymer known as polyether ether ketone (PEEK) has showed promise for use in a wide range of sectors, including dentistry. PEEK is becoming increasingly widely used by dentists despite being less well-known than titanium and zirconium. This is due of its excellent toughness and endurance, its natural color, and its biocompatibility with both hard and soft tissue.

What materials are used in the implant restoration?

The most widely utilized material for the "finishing touch" of an implant is ceramic, with porcelain being the most preferred variety. Although it is more likely to cause dental sensitivity and is the most expensive choice, it looks and feels the most like a real tooth.

Porcelain-fused-to-metal (PFM) restorations are a subset of all-ceramic restorations. By using mixtures of precious (for example, 40% gold with palladium, platinum, silver, etc.), semi-precious (for instance, 25% precious with tin, cobalt, zinc, etc.), or non-precious (for instance, cobalt, chromium, tungsten, etc.) metals as the prosthetic's core, this type combines the aesthetics of porcelain with the durability of metal.

PFM crowns may have a disadvantage in that if the gums recede, a gray line of metal may show at the gumline. They can, however, be a sensible choice for lengthy bridges where the metal is essential for strength. PFM crowns also come with the same risk of metal allergy as implant posts, while being less expensive than all-porcelain crowns.

Use of zirconia over titanium for a look that is as aesthetically acceptable as porcelain is a technique comparable to PFM, albeit it can be more difficult to color-match teeth. Additionally, they cost more than some of the alternatives.

The IPS e.max lithium disilicate glass-ceramic is an additional ceramic choice. With precise tooth shade matching and long-lasting performance, e.max is a high-strength zirconia substitute that may be utilized in crowns, bridges, and hybrid abutments.

Of course, all-metal crowns, such those made of full-cast gold, continue to be a popular choice because they are durable and unbreakable. They are most suitable for single implants in molars or other out-of-sight tooth placements due to their high price of precious metals and lack of resemblance to natural teeth.

Last but not least, all-resin dental crowns are an affordable option, but because they are more likely to fracture than PFMs, their use is typically limited to temporary crowns. But when it comes to dentures, acrylic resin is a lighter, more affordable option than porcelain dental implants.
