ALL-ON-4 Dental Implants with photos
Posts for: March, 2022
Historically speaking, implants are a recent blip on the centuries-long march of dental progress. But few innovations in dentistry can match the impact of implants in its short history on dental function and appearance.
Dental implant therapy has already established itself as a restoration game-changer. But it also continues to improve, thanks to a number of emerging technologies. As a result, implant restorations are far more secure and life-like than ever before.
Here are 3 examples of state-of-the-art technologies that continue to improve this premier dental restoration.
CT/CBCT scanning. Functional and attractive implants depend on precise placement. But various anatomical structures like nerves or sinuses often interfere with placement, so it's important to locate these potential obstructions during the planning phase. To do so, we're increasingly turning to computed tomography (CT). This form of x-ray diagnostics is the assembly of hundreds of images of a jaw location into a three-dimensional model. This gives us a much better view of what lies beneath the gums.
Digital-enhanced planning. Implant success also depends on careful planning. And, it isn't a one-sided affair: The patient's input is just as important as the dentist's expertise. To aid in that process, many dentists are using digital technology to produce a virtual image of a patient's current dental state and what their teeth may look like after dental implants. This type of imaging also allows consideration of a variety of options, including different sized implants and positions, before finalizing the final surgical plan.
Custom surgical guides. To transfer the final plan details to the actual implant procedure, we often create a physical surgical guide placed in the mouth that marks the precise locations for drilling. We can now produce these guides with 3-D printing, a process that uses computer software to produce or "print" a physical object. In this case, the 3-D printer creates a more accurate surgical guide based on the exact contours of a patient's dental arch that's more precise than conventional guides.
Obtaining a dental implant is a highly refined process. And, with the aid of other advances in dental technology, it continues to provide increasing value to patients.

You can't rid your body of the trillions of bacteria that inhabit it—nor would you want to. Many of the thousands of species taking up residence in and around you are beneficial to you.
That includes the bacteria in your mouth living together in an invisible community known as a "microbiome." Our immune systems gradually learn to discern between those that mean us well and those that don't, and for the most part leave the former alone.
But although harmful bacteria are in the minority, they can still cause devastating infections like tooth decay and gum disease. Fortunately, we've identified their "base of operations"— a thin film of leftover food particles, that when joined with bacteria is referred to as dental plaque. Plaque buildup serves as the primary food source for harmful bacteria.
We can prevent disease by depriving bacteria of this food source—by brushing and flossing daily to remove plaque buildup. Oral hygiene, along with regular dental care, is the best way to reduce harmful oral bacteria and our risk for disease.
Without these measures disease can develop and advance quickly, damaging the teeth, gums and supporting bone. And in cases of advanced gum disease, dentists often turn to antibiotics to reduce bring rampant bacteria under control.
But we've learned the hard way that overused antibiotic therapy can cause more harm than good. For one, it can create resistance within the bacteria we're targeting that often render the antibiotics we're using impotent.
Furthermore, antibiotics can't always discern "good" bacteria from "bad." Beneficial strains may be destroyed in the process, leaving the rich bacterial "microbiome" in our mouths a wasteland. And as we're learning, our health could be worse for the loss.
To avoid this, we're beginning to use treatment applications that narrowly target malevolent bacteria while avoiding more benevolent strains. One helpful advance in this matter was the development of the Human Oral Microbiome Database HOMD, part of which has enabled us to precisely identify the individual bacteria that cause certain diseases. This has made it easier to target them with specific antibiotic drugs.
We still have much to learn about the microscopic world within our mouths. As we do, we can better cooperate with those "inhabitants" that help us maintain our health while fighting those that cause us harm.

Porcelain crowns are most commonly used to protect and support teeth damaged by disease or trauma. Today's highly advanced crowns are more effective than ever—and more life-like and attractive.
For instance, dentists often install a crown for a tooth that's endured long-term decay. It's often necessary for a dentist to remove significant portions of affected dentin of a decayed tooth over time, which weakens its overall structure. By crowning the tooth, a dentist can both protect it from further decay and provide it structural support. For similar reasons, dentists routinely place crowns after root canal treatments.
To fulfill their role in preserving and strengthening teeth, crowns must be made of durable materials. For this reason, earlier generations of dentists often turned to crowns composed of precious metals like gold or silver, which could withstand daily chewing forces. But these metal crowns did have one downside: Other than shape, they little resembled real teeth.
Crowns later became more life-like around the middle of the 20th Century with the advent of a type of crown composed of a metal shell encased with a tooth-colored porcelain layer. Marrying functionality with aesthetics, these porcelain-fused-to-metal (PFM) crowns became quite popular and reigned supreme until the early 2000s.
At that time, advances in dental porcelain led to the emergence of the all-ceramic crown. The effort had started a full decade before when dental labs began adding a material called Lucite to porcelain to give it strength. With further improvements, these new porcelain materials, which no longer required metal for durability, soon displaced PFMs as the most commonly installed crown.
Today's dental patient now has more crown choices than patients in previous generations. Especially useful for visible teeth (those in the "Smile Zone"), an all-ceramic crown now enhances rather than detracts from a tooth's appearance. Metal and PFM crowns haven't gone away either—they're often used with teeth that encounter heavy biting forces like molars, and which are not as noticeable.
With more choices, patients no longer need sacrifice their appearance to protect their teeth. You can now preserve a troubled tooth—and still maintain an attractive smile.
