[ Magok Implants_07 ] Implant Prostheses: What’s the Difference Between Zirconia and PFM?

Hello.

We are 서울디아치과, a dental clinic in Magok that provides thoughtful care to earn your trust.

In Part 6, we organized the number of visits and the time required for each stage of implant treatment.

Today, we’ll discuss a question you must decide on toward the end of implant treatment.

"What material would you like for your prosthesis?"

Zirconia? PFM?

For those hearing these terms for the first time, even the names may seem unfamiliar.

Perhaps that is why many people say,

"I’ll just go with whatever you recommend."

However, each material has different characteristics, advantages, and disadvantages, so it is important to choose the one that suits your situation.

Today, 서울디아치과 will clearly explain the key points for comparing zirconia and PFM.

What Are Implant Prostheses?

Implants consist of three main parts.

• Fixture: the screw-like part placed into the bone

• Abutment: the post that connects the fixture and crown

• Crown: the part that is actually visible as the tooth

The difference between zirconia and PFM, which we are discussing today, is the material used for this crown.

What Is PFM?

PFM stands for Porcelain Fused to Metal and is made by placing porcelain over metal.

The inside is made of metal to provide strength, while the outside is made of porcelain to match the color of a natural tooth.

It is a traditional prosthetic material that has been used for a long time.

Advantages

• Its high strength makes it suitable for areas that receive strong chewing forces, such as the molars

• It is relatively affordable

• A substantial amount of long-term clinical data has been accumulated

Disadvantages

• If the gums recede because of the metal inside, a black line may become visible along the gumline

• It may not be suitable for people with metal allergies

• The porcelain portion may fracture over time

What Is Zirconia?

Zirconia is a prosthetic material made entirely of ceramic, without metal.

"Dental diamond"

It is known for its high strength and excellent aesthetics.

Advantages

• Without metal, the gumline looks natural

• There is no concern about metal allergies

• Its color is similar to that of natural teeth, making it aesthetically pleasing

• Its very high strength provides good durability

• It rarely changes color

Disadvantages

• It costs more than PFM

• Some opinions suggest that it may wear down the natural tooth opposite it

• (However, this has improved significantly with recent technological advances.)

Zirconia vs. PFM: At a Glance

	Zirconia	PFM
Material	Ceramic	Metal + porcelain
Strength	Very high	High
Aesthetics	Excellent	Average
Gumline	Natural-looking	A black line may appear
Metal allergy	None	Possible
Cost	Relatively high	Relatively low

Which One Should You Choose?

In summary, it is simple.

When zirconia may be more suitable

• For those who want an aesthetically natural result

• For those with a metal allergy

• For those whose gums may recede

• For highly visible areas, such as the front teeth

When PFM may be more suitable

• For those for whom cost is an important consideration

• For molar areas that receive strong chewing forces

• For those who prefer a material with more extensive clinical data than zirconia

However, there is one important point.

Although the material you choose is important, how precisely it is made and how well the bite is adjusted determine the lifespan of the prosthesis.

Even when a good material is used, inaccurate fabrication or placement can shorten its lifespan.

Conversely, if the material suits your situation and the prosthesis is fabricated precisely, you may be able to use it comfortably for much longer.

At 서울디아치과, we recommend the most suitable material by considering the condition of your teeth, your bite, your aesthetic needs, and your budget.

We are happy to provide convenient consultations through Naver TalkTalk or appointments.

Please feel free to check with us without any pressure.

Now, shall we briefly summarize today’s discussion?

• Implant prostheses are divided into zirconia and PFM according to the crown material

• PFM is strong and affordable, but a black line may appear along the gumline

• Zirconia offers excellent aesthetics and no concern about metal allergies

• Precise fabrication and bite adjustment are as important as material selection in determining the lifespan

• It is important to decide on the material that suits your situation together with a professional

"Can I fly after getting an implant? When can I return to daily activities?"

I hope you stay healthy and have a day filled with bright smiles. ^^
