Some patients who wear dentures face a kind of Catch-22: their denture fit may have loosened and become uncomfortable over time due to continued bone loss, yet the same bone loss prevents them from obtaining dental implants, a superior tooth replacement system to dentures.
But there may be a solution to this dilemma that combines the stability of implants with a removable denture. A set of smaller diameter implants — “mini-implants” — can support a removable denture with less bone than required by a conventional implant.
Like all living tissue, bone has a life cycle: after a period of growth, the older bone dissolves and is absorbed by the body, a process known as resorption. The forces generated when we bite or chew are transmitted by the teeth to the jawbones, which stimulates new bone formation to replace the resorbed bone. When the teeth are lost, however, the stimulation is lost too; without it, resorption will eventually outpace bone growth and repair, causing the bone mass to shrink.
Removable dentures also can’t supply the missing stimulation — bone loss continues as if the dentures weren’t there; and due to the compressive forces of a denture, bone loss accelerates. As the jawbone structure used to originally form the denture’s fit eventually shrinks, the denture becomes loose and difficult to wear. It’s possible to adjust to the new jaw contours by relining the dentures with new material or creating a new set of dentures that match the current bone mass. Without adequate bone, fixed crowns or bridges anchored by conventional implants may also be out of the picture.
On the other hand, mini-implants with their smaller diameter need less bone than the traditional implant. A few strategically placed within the jaw are strong and stable enough to support a removable denture. One other advantage: these mini-implants can be installed in one visit with local anesthesia and usually without the need for incisions or stitches.

We always look forward to seeing our patients, but not all of you look forward to seeing us! If you’re one of them, don’t worry — we don’t take it personally. Dental anxiety prevents many people from seeking the care they require to restore or maintain a healthy smile.
But if dental problems are allowed to progress, they can affect not only the beauty of your smile and health of your mouth, but your overall wellness, too. Infection can travel from the mouth to other areas of the body, and dental disease exacerbates chronic health conditions like heart disease or diabetes.
Fear should never be an obstacle (in the immortal words of President Franklin Roosevelt, “…the only thing we have to fear is fear itself…”). And fortunately there are some safe options for those of us who can’t get past our anxiety when it comes to dental care:
Oral Sedation. A sedative medication can be prescribed that you take by mouth approximately an hour before your dental visit to minimize anxiety and promote relaxation.
Intravenous (IV; “intra” – inside, “venous” – vein) Sedation. If oral sedation isn’t entirely effective in facilitating treatment, then a medication combining a sedative for relaxation and a pain-blocking anesthetic can be delivered through or small needle or catheter that is gently inserted into a vein. This is referred to as “conscious sedation” because you are in a semi-awake state during which you are able to respond to verbal direction. It takes effect quickly, and you can come out of it quickly. However, you may not remember much about your procedure. It is very different from general anesthesia during which you are completely unconscious.
Dentists who offer IV sedation receive extensive training after which we must pass an exam and apply for a special permit that we maintain through continuing education. We carefully screen patients for eligibility and monitor you throughout so you can rest easy before, during, and after your procedure.

Some moviegoers have been known to crunch popcorn, bite their fingers or grab their neighbor’s hands during the intense scenes of a thriller. But for one fan, the on-screen action in the new superhero film Black Panther led to a different reaction.
Sophia Robb, an 18-year-old Californian, had to make an emergency visit to the orthodontic office because she snapped the steel wire on her retainer while watching a battle scene featuring her Hollywood crush, Michael B. Jordan. Her jaw-clenching mishap went viral and even prompted an unexpected reply from the actor himself!
Meanwhile, Sophia got her retainer fixed pronto—which was exactly the right thing to do. The retention phase is a very important part of orthodontic treatment: If you don’t wear a retainer, the beautiful new smile you’re enjoying could become crooked again. That’s because if the teeth are not held in their new positions, they will naturally begin to drift back into their former locations—and you may have to start treatment all over again…
While it’s much more common to lose a removable retainer than to damage one, it is possible for even sturdy retainers to wear out or break. This includes traditional plastic-and-wire types (also called Hawley retainers), clear plastic retainers that are molded to fit your teeth (sometimes called Essix retainers), and bonded retainers: the kind that consists of a wire that’s permanently attached to the back side of your teeth. So whichever kind you use, do what Sophia did if you feel that anything is amiss—have it looked at right away!
When Black Panther co-star Michael B. Jordan heard about the retainer mishap, he sent a message to the teen: “Since I feel partly responsible for breaking your retainers let me know if I can replace them.” His young fan was grateful for the offer—but even more thrilled to have a celebrity twitter follower.
