If you have missing teeth, dental implants are the state-of-the-art tooth replacement system. They act as substitutes for natural tooth roots, stabilizing the bone with which they fuse and become integrated with. This protects the remaining bone and prevents its further loss, the natural occurrence after the natural teeth are lost. Done correctly, implants can offer a long-term solution to the problem of missing teeth.
Key factors assuring dental implant success are having an experienced dental team consisting of:
- A surgeon (periodontist or oral surgeon, or dentist trained in surgical techniques to place the implants)
- A dental technician who will design the crowns (tooth portion of the implant)
- A restorative dentist to place the crowns
The whole team is necessary to plan the process as well as carry out their individual roles. They will ensure that there is enough bone and that it is in the right place prior to treatment to allow for proper implant position, and that the implant/s are correctly placed, which is necessary to allow for natural aesthetics and proper function.
Replacing missing teeth is imperative to maintaining normal oral health and function. Dental implants will help support the entire structure of the face. If back teeth are lost, the vertical height of the lower face and mouth can begin to collapse, negatively impacting biting function and causing creasing and cracking of the lips and facial skin, resulting in a prematurely aged look.
Implants differ from bridgework in several ways, making them the most favorable option for tooth replacement in many cases. For starters, they do not affect adjacent teeth, nor do they decay like teeth, and they are less susceptible to gum disease. In the long-term, implants are a more cost-effective solution based on the fact that once they are placed, their life expectancy is longer than bridgework.

Dental implants are now the gold standard for tooth replacement. Why? Because not only do they offer the longest-lasting method of restoring missing teeth, but they also help mitigate one of the greatest problems associated with tooth loss — the loss of underlying bone structure. While standard dental implants have been around since the 1970s, mini-implants are a smaller version of the same technology that have recently come into their own. Here are a few things you should know about them.
Mini-implants rely on the same structure and principles as their larger relatives.
Like standard implants, mini-implants are screw-shaped devices made of titanium which are set into the bone of the jaw. Put in place permanently, they become fixed to the bone itself, which grows around and fuses to the implant. Or, they can be used as temporary anchors for the attachment of other dental work.
Mini-implants are a great option for attaching lower overdentures.
Overdentures (implant-retained dentures) are now considered the standard of care for people who have lost all of their teeth in one or both jaws. But the undesired movement of lower dentures has been a perennial problem for many denture wearers. One key use of mini-implants is to anchor overdentures to the lower jaw. Just two mini-implants provide the stability needed to attach a set of lower dentures sturdily, giving the denture wearer increased dental function — and a restored sense of confidence.
Mini-implants offer some real benefits in orthodontics.
TADS (Temporary Anchorage Devices), another type of mini-implants, are finding increasing use alongside of orthodontic appliances (braces). Braces move teeth by placing small forces on them, which are transmitted by a wire. The wire must be anchored at a “fixed” point: usually, other teeth; but it may cause these teeth to move as well! TADS offer an anchorage point that's truly immovable. They help to speed up orthodontic treatment, and give more accurate control as well.
Placing mini-implants is a relatively simple process.
It's an office procedure done by an experienced clinician, normally under local anesthesia. Most patients tolerate the procedure very well, experiencing only minor discomfort. In some cases, a single two-hour visit is all that's needed for implant placement, and the patient can go home and eat a steak afterward!
Mini-implants may be more economical than you think.
These smaller cousins of standard implants are often easier to place. They save treatment time, and, if you're a denture wearer, they may be compatible with your existing dentures. If your dental situation could benefit from using mini-implants, you should give them serious consideration.

A dental implant can permanently restore the form and function of a missing natural tooth. But there’s an important prerequisite for this smile-transforming therapy — you must have enough bone remaining at the implant site to securely anchor the implant and ensure proper crown placement for the most natural looking result.
Patients who don’t meet this prerequisite may need to consider other restorative options. In some cases, however, we may be able to encourage sufficient bone growth to support an implantation through a technique called bone grafting.
Bone grafting involves opening the gum tissues at the intended implant site to expose the underlying bone. We then place the grafting material (usually a processed material) around the bone, sometimes with collagen membranes that serve as subterranean band-aids to guide bone growth. In most cases, the graft is actually a scaffold for the natural bone to grow upon; the natural bone will eventually replace the graft material. The procedure is normally performed with local anesthesia to minimize discomfort.
While bone grafting is a fairly routine procedure, it shouldn’t be undertaken unless there’s a firm prognosis it can successfully support a future implant. We must therefore determine if anything else in your oral health would disqualify you as an implant candidate, even if sufficient bone existed or not. We must also determine if there’s enough remaining bone currently at the site to even attach a bone graft.
Once we’re satisfied that bone grafting would be both possible and helpful, we must then consider what type of grafting material to use. If we’re only replacing one tooth we may choose to use an autograft, bone material taken from another area of your own body. Although autografts have advantages because of their regeneration ability, it does involve creating another surgical site within the body. In most cases we may use processed materials, for example allografts, material that originates from another human being; xenografts, taken from another species of animal; or synthetic (man-made) materials. Regardless of the source, these materials are first processed to be safe for human use.
If successful, the regeneration process will result in enough new bone structure to make dental implants a reality. Your mouth will be healthier — and your resulting smile will be more beautiful than ever.

Dental implants are a popular and effective restoration for lost teeth, if there’s enough bone present to support the implant. That might not be the case, however, because without the stimulation of the lost tooth, the bone may dissolve (resorb) over time. It’s possible, however, that you may need to re-grow bone in the back area of the upper jaw where your upper (maxillary) sinus is located.
Sinuses are air space cavities located throughout the skull. This feature allows your head to be light enough to be supported by your neck muscles. Inside each sinus is a membrane that lines your sinus cavities, nasal passages and other spaces. The maxillary sinus is located on each side of the face just below the eyes. Pyramidal in shape, the floor of the pyramid lies just above the upper back teeth.
A surgeon approaches the sinus through the mouth, with the objective of moving the sinus membrane up from the floor of the sinus. This is accomplished by placing bone-grafting material in the area. Over time the body uses the grafting material as a scaffold to produce new bone that then replaces the grafting material. The resulting new bone becomes the support for the implant.
If enough bone exists to stabilize an implant but not anchor it, then the surgeon can approach the sinus from the same opening that’s used for the intended implant site, insert the grafting material, and install the implant during the same procedure. If not, the surgeon creates a small “window” laterally over the teeth to access the sinus and insert the graft. The implant is installed a few months later after the new bone is created.
The procedure usually requires only a local anesthetic, although some patients may require additional sedation or anti-anxiety medication. After the surgery, you normally experience mild to moderate swelling and discomfort, about the same as having a tooth removed. All these symptoms can be managed with non-steroidal, anti-inflammatory pain medication and a decongestant for minor congestion in the sinus. We might also prescribe an antibiotic to help prevent infection.
Although this procedure adds another step and possibly more waiting time to implantation, it gives you an option you wouldn’t otherwise have — a life-like, effective replacement of your back teeth with dental implants.

Dental implants are one of the best tooth replacement systems available. But while they can rejuvenate patients’ smiles and potentially provide a lifetime of service, they require thorough planning and preparation before the implant is inserted.
The process begins with the assembling of your treatment team. Implants require the training and expertise of a number of professionals who collaborate during the process: a dental specialist, like an oral surgeon, periodontist or a general dentist trained in implant dentistry, who surgically installs the implant; a dental technician who fashions the permanent life-like crown that will attach to your particular implant; and a restorative dentist who begins and ends the process with you — from initial consultation and planning to the permanent crown attachment. You, the patient, are also part of the team — your input and informed choices are essential to a successful outcome.
Your restorative dentist will take the first steps to develop your treatment plan. It begins with both a dental examination and a general health assessment to determine your fitness for any surgery. The dental examination serves to evaluate the site where the proposed implant or implants will be placed, along with x-rays for assessing the quantity and quality of bone at the site. Next, the dentist will create study models of your mouth to assess bite, and possibly take photographs to guide decisions on the implant crown’s color and appearance. The last step may be the development of surgical guides to ensure accurate placement of the implants by the surgeon.
One of the biggest questions to answer at this stage is whether or not you have sufficient bone mass to support the implant. You may have experienced significant bone loss due to disease or from resorption (the dissolving of bone) because of tooth loss. Insufficient bone mass can be remedied with a bone graft placed within the site that stimulates bone growth, which if successful will provide enough bone to support the implant.
While this preparatory phase before implant placement can be very involved, it’s absolutely necessary for ultimate success. The careful planning and prep work performed by your implant team — and your own participation in the process — will ensure that you’ll be happy with your new implants and your new smile.
