Implant-SupportedDenturesCouldBoostYourJawboneHealth

People have depended on dentures for generations—and they still do. That's because they work, both in restoring dental function and a smile marred by missing teeth.

But they have one major drawback related to bone health. That's because living bone has a life cycle: as older cells die, new ones form to take their place. The pressure generated when we chew stimulates this growth. But when this stimulus goes missing along with the teeth, the cell replacement rate slows and bone volume and density gradually diminishes.

Traditional dentures can't transmit this chewing pressure stimulus. And because they rest directly on the gum ridges, they can adversely affect the underlying bone and actually accelerate bone loss.

But implant technology potentially solves this bone loss problem with dentures by using implants rather than the gums to support them. It's a two-fold benefit: first, the implants relieve much of the irritation to the gums and bone caused by traditional dentures. Primarily, though, the implants themselves can slow or even stop continuing bone loss.

Most implants are made of titanium, not only because it's compatible with the body, but also because it has an affinity with bone. Over time bone cells grow on the titanium post imbedded in the jawbone. This process not only creates stability and durability, it can improve bone health.

In recent years dentists have incorporated implants with dentures to create two exciting treatment options. With one option, the dentist installs two or more implants in the jaw, to which a specially fitted removable denture can be attached. You would still have the ease of removing the denture for cleaning, while gaining greater stability and a reduced risk of bone loss.

The other option is a fixed denture (or bridge) attached permanently to implants. For this option, a patient's jawbone must be adequate and healthy enough to support at least four to six implants. A fixed denture is also often costlier and more complex than a removable denture, but it can feel more like real teeth. It also promotes better bone health too.

Although both options are more expensive than traditional dentures, they can pay dividends for long-term dental health. Implants could help you enjoy your new dentures and resulting smile for a long time to come.

ChoosingaScreworCementtoAttachanImplantCrown

If you've lost a tooth, you have a number of options for replacing it. Perhaps the best choice in terms of lifelikeness and durability is a dental implant.

All implants have the same basic architecture: a titanium metal post imbedded in the jawbone to replace the root; and an abutment, a metal collar that links the post with a lifelike porcelain crown. But implants can vary in how the crown attaches to the abutment and post — either cemented to the abutment or screwed through the abutment to the post.

Either method will permanently secure the crown to the implant. But there are advantages and disadvantages for each.

A screw-retained crown may better facilitate any future repair that might be needed. For a skilled dentist it's a simple matter of removing the screw and then the crown from the abutment. There's less risk of damage to the implant during repairs or crown replacement. Many dentists also prefer screws for crowns placed at the same time they're installing the implant post (a procedure called immediate loading).

The screw access hole, however, could pose a cosmetic problem. Although we can cover it over with tooth-colored filling, it may still be noticeable and unattractive especially for a tooth visible when you smile (in the smile zone). There's also the possibility the porcelain around the access hole could chip.

By contrast, cemented crowns have a smooth, unbroken surface and are aesthetically ideal for smile zone teeth. But the cement could interact poorly with gum and bone tissue in some patients, causing inflammation and possible bone loss.

And unlike screw-retained crowns, cemented crowns are difficult to remove for implant repair. We may have to drill through the crown to access the screw between the abutment and the post, and then repair it cosmetically if we use the same crown. Again, the final result may not be quite as visually appealing.

In the end, it will depend on the implant's location, how your body reacts to the cement or your dentist's preference. In either case, though, you'll have a tooth replacement that's functional, life-like and able to endure for many years to come.

Dental ImplantsDiscover the unique benefits you’ll enjoy when you get dental implants in Honolulu, HI.

Dealing with tooth loss? If so, you may be pulling your hair out trying to figure out what to do to get your smile back on track. Don’t worry; this is where our Honolulu, HI, restorative dentist Dr. Ken Yasuhara comes to the rescue. We pride ourselves on creating customized dental restorations to ensure that your new tooth looks and feels exactly the way you want. Want to learn how dental implants can help you? Well, you’ve come to the right place.

What is a dental implant?

An implant is a tiny metal post or screw that, in essence, functions just like tooth roots. In fact, an implant is designed to take the place of your missing tooth’s roots. In order to do this, an implant will need to be placed into the jawbone where the tooth once was. This provides a strong, long-term foundation from which to support a false tooth.

What should I know about getting dental implants?

Implants are the next best thing to real teeth and they can last the rest of your life if you care for them properly. Of course, this doesn’t always mean that an implant is the best option for replacing your missing tooth or teeth. It’s important that you understand what goes into this treatment so that you can decide, along with our Honolulu dentist, if this is the right tooth replacement option for you.

Here’s what you should know about getting dental implants:

  • In order to get an implant you will need to undergo minor surgery right here in our office. This procedure is performed under local anesthesia, and it allows us to place the implant into the jawbone.
  • An implant is made from biocompatible metal, which means that the jawbone and oral tissue will treat the metal implant like it’s a natural part of the body. As the bone and tissue heal from surgery, they will grow around the implant and fuse together with it to become one strong unit.
  • Sometimes another minor surgery is required in order to place a second part of the implant, known as the abutment, on top of the implant to connect the metal post with the dental crown. Whether you require this surgery or not will depend on the type of dental implant you receive.
  • While an implant is designed to replace a single missing tooth, if you are missing some or all of your teeth then multiple implants can be placed along the arches of the jaw to support full or partial dentures.
  • Implants are a great option for healthy adults who are missing one or more teeth. Implants are not right for children or young teens because their jawbones are still developing.

If you are an adult faced with tooth loss in Honolulu, HI, we know that nothing is more important than getting your smile back. Let our aesthetic dentist Dr. Yasuhara and his dental team help you. Call us today to schedule a consultation.

DentalImplantscanReplaceYourWholeToothNotJustWhatYouSee

If you've lost a tooth or need to have one extracted, you have to decide how to replace it. Of all the options available none can match both the lifelikeness and function of a dental implant.

A dental implant is a prosthetic (false) tooth that mimics the root of a natural tooth. Once that implant root form fuses to the surrounding bone, we attach the crown, which is the part of the tooth you can see.

While other replacement options like bridges or dentures can restore the lifelikeness of the tooth crown, they don't replace the root. An implant's titanium post can: using a minor surgical procedure we imbed the post into the bone. Because bone cells have a natural affinity with titanium, they will grow around and adhere to the post over a few weeks after surgery. This further adds strength to the implant's hold in the bone.

Although the attachment isn't exactly like natural teeth, it can maintain this hold for many years. And because it encourages bone growth, a dental implant will help minimize bone loss, a natural consequence of losing teeth. Other replacement options can't do that.

Of course, implants are more costly than other restorations. With an attached crown, an implant can replace any number of teeth. But if you have extensive tooth loss, bridges or dentures would be more cost-effective selections.

But even then, implants could still play a role. We can strategically place a small number of implants as supports for a bridge or even a removable denture. Not only will the implants better secure their attachment, they'll also stimulate bone growth.

Is a dental implant the right choice for you? Visit us for a complete examination and evaluation. Afterward we can discuss your options and whether this phenomenal tooth restoration method could help restore your smile.

YoullExperienceLittletoNoDiscomfortDuringandAfterImplantSurgery

You’ve decided to obtain dental implants for your missing teeth. It’s a good choice — they provide the closest restoration to the function and appearance of natural teeth. You will, however, need to undergo a surgical procedure to imbed the implants’ threaded titanium posts into supporting bone.

It’s understandable if you’re a little apprehensive about undergoing surgery. We’re here, though, to set your mind at ease: implantation is a relatively minor procedure carefully planned in advance. Most patients experience no discomfort during the procedure and very little afterward.

We begin by completely numbing the surgical site with a local anesthetic. If you have a high level of anxiety, we can also administer a sedative or similar medication to help you relax. We then access the underlying bone through a series of incisions that create a flap in the gum tissue that we’ll later suture closed.

It’s quite common to have prepared a surgical guide or template beforehand. The template placed in the mouth marks the exact site for a small channel (or hole) we create in the bone. We then incrementally increase the size of the hole by drilling until it matches precisely the implant’s size and shape. This takes time to avoid overheating and damaging the bone.

We then remove the implant from its sterile packaging and insert it into the opening. We’ll also take x-rays to ensure correct positioning, which is critical for achieving an attractive result. We then suture the gum flap in place using stitches that will eventually dissolve. The implant will then integrate with the bone for a few weeks to create a strong, durable hold before we continue with the restoration.

Most patients can manage any post-surgical discomfort with mild anti-inflammatory pain relievers like aspirin or ibuprofen, although we can prescribe something stronger if you need it. We may also prescribe a mouthrinse with an anti-bacterial agent like chlorhexidine for you to use while the gums are healing to reduce the risk of infection.

Implant surgery is part of a long process that will eventually result in regaining the function of your lost teeth. What’s more, undergoing this minor procedure will also help you regain something just as important — a beautiful smile.
