Modern dentistry offers several great ways to permanently replace missing teeth, including high-tech dental implants and traditional fixed bridgework. But sometimes, for one reason or another, it isn’t possible to have these treatments done right away. If you need an aesthetic way to temporarily replace missing teeth, a flexible partial denture could be the answer you’re looking for.
Certain kinds of removable partial dentures (RPDs) can be used as permanent tooth replacement systems, especially for people who aren’t candidates for dental implants or fixed bridges. But in the past, if you needed a temporary tooth replacement, one of the few alternatives was the type of rigid RPD often called a “flipper.” This consists of a firm, relatively thick acrylic base that supports one or more lifelike replacement teeth. It attaches to the “necks” of existing natural teeth via metal clasps, which gives it stability and strength.
However, the same rigidity and thickness that gives these rigid RPDs their durability can make them uncomfortable to wear, while the acrylic material they are made of is capable of staining or breaking. Over time, the RPDs are prone to coming loose — and they are also easy to flip in and out with the tongue, which gives them their nickname.
Flexible partial dentures, by contrast, are made of pliable polyamides (nylon-like plastics) that are thin, light and resistant to breakage. Instead of using metal wires to attach to the teeth, flexible RPDs are held securely in place by thin projections of their gum-colored bases, which fit tightly into the natural contours of the gumline. Their elasticity and light weight can make them more comfortable to wear. Plus, besides offering aesthetic replacements for missing teeth, their natural-looking bases can cover areas where gums have receded — making existing teeth look better as well.
All RPDs must be removed regularly for thorough cleaning — but it’s especially important for flexible RPD wearers to practice excellent oral hygiene. That’s because the projections that hold them in place can also trap food particles and bacteria, which can cause decay. And, like most dentures, RPDs should never be worn overnight. Yet with proper care, flexible RPDs offer an inexpensive and aesthetic way to temporarily replace missing teeth.
Restoring chipped, stained or decayed teeth with dental porcelain is a tried and true method that’s been used for decades. In recent years, though, restorations made with composite resin have become a popular alternative.
Made of a plastic-based matrix with added glass filler, composite resin can be molded and bonded to teeth to replace missing structure with color to match. While they can’t be used for every problem situation, they’re an efficient and economical way to transform your smile.
Here are 4 advantages for using composite resin to restore moderately defective teeth.
They require very little tooth preparation. Crowns, veneers and other porcelain restorations require removing some healthy tooth structure to accommodate them. With the development of stronger bonding materials, composite resins can restore even many large defects in teeth caused by decay or trauma with little structural removal and still remain durable.
Most composite resin restorations are “single-visit” procedures. Unlike porcelain restorations, applying composite resin doesn’t require a dental lab, a process that can take multiple visits. In most cases, a skilled dentist can apply them during a single visit.
They have excellent color matching capabilities. We usually think of teeth as one single shade of white — actually, a single tooth can have varying gradations of color from the root to the tip. As mentioned before, composite resins can be prepared to match those color shades precisely, so your restored teeth look natural and blend well with your other teeth.
Composite resins can be an effective temporary fix for young injured teeth. Because children’s teeth are still developing, permanent restorations for traumatized teeth aren’t usually advisable until they’ve fully matured. Composite resin can be used to restore a young tooth’s form and function until it’s ready for a permanent solution.
