Root Coverage Grafting:

When recession of the gingiva occurs, the body loses a natural defense against both bacterial penetration and trauma. When gum recession is a problem gum reconstruction using grafting techniques is an option .

The body typically has a collar of thick, dense gingiva around the tooth, further from the tooth is thin elastic mucosa. Some individuals have limited gingiva due to trauma or other factors.

When there is only minor recession, some healthy gingiva often remains and protects the tooth, so that no treatment other than modifying home care practices is necessary. However, when recession reaches the mucosa, the first line of defense against bacterial penetration is lost.

In addition, gum recession often results in root sensitivity to hot and cold foods as well as an unsightly appearance to the gum and tooth. Also, gum recession, when significant, can predispose to worsening recession and expose the root surface, which is softer than enamel, leading to root caries and root gouging.

A gingival graft is designed to solve these problems. A thin piece of tissue is taken from the roof of the mouth, or gently moved over from adjacent areas, to provide a stable band of attached gingiva around the tooth. The gingival graft may be placed in such a way as to cover the exposed portion of the root.

The gingival graft procedure is highly predictable and results in a stable healthy band of attached tissue around the tooth.

Crown lengthening:

When decay occurs below the gumlime, it may be necessary to remove a small amount of bone and gum tissue. Your dentist may ask for this procedure before he or she makes a new crown for your tooth.

Reshaping The Gum and Supporting Tissues: This will allow your general dentist adequate room to place a quality final restoration.

Teeth can often be hidden underneath excess gum tissue, making them appear short and unattractive. A procedure(esthetic crown lengthening) can be performed to expose the natural shape of the teeth. This is often done after orthodontics. Teeth are also frequently lengthened before crowns or veneers are fabricated.

Major and Minor Bone Grafting

Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants. Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and esthetic appearance.

Major Bone Grafting

Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw. Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration.

Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patient's own bone. This bone is harvested from a number of different sites depending on the size of the defect.

 

If there is a defect down in the bone, often times a bone graft can be placed to stimulate new bone formation

We use combinations of synthetic and natural bone blended with an antibiotic to fill the defect.

Research has shown we can expect a 60% fill of the defect 80% of the time.

Sinus Lift Procedure

The maxillary sinuses are behind your cheeks and on top of the upper teeth. Sinuses are like empty rooms that have nothing in them. Some of the roots of the natural upper teeth extend up into the maxillary sinuses. When these upper teeth are removed, there is often just a thin wall of bone separating the maxillary sinus and the mouth. Dental implants need bone to hold them in place. When the sinus wall is very thin, it is impossible to place dental implants in this bone.

There is a solution and it's called a sinus graft or sinus lift graft. The dental implant surgeon enters the sinus from where the upper teeth used to be. The sinus membrane is then lifted upward and donor bone is inserted into the floor of the sinus. Keep in mind that the floor of the sinus is the roof of the upper jaw. After several months of healing, the bone becomes part of the patient's jaw and dental implants can be inserted and stabilized in this new sinus bone.

The sinus graft makes it possible for many patients to have dental implants when years ago there was no other option other than wearing loose dentures.

If enough bone between the upper jaw ridge and the bottom of the sinus is available to stabilize the implant well, sinus augmentations and implant placement can sometimes be performed as a single procedure. If not enough bone is available, the Sinus Augmentation will have to be performed first, then the graft will have to mature for several months, depending upon the type of graft material used. Once the graft has matured, the implants can be placed.

Inadequate bone in the top back jaw.

Bone is grafted into the sinus to increase the height of the jaw. Now there is adequate bone to place a dental implant.

Guided Tissue Bone Regeneration

Traditionally, eliminating the gum pockets by trimming away the infected gum tissue and by re-contouring the uneven bone tissue treats gum disease. Although this is still an effective way of treating gum disease, new and more sophisticated procedures are used routinely today.

Guided Tissue Bone Regeneration "regenerates" the previously lost gum and bone tissue. Most techniques utilize membranes, which are inserted over the bone defects. These membranes are bio-absorbable which do not require removal. Other regenerative procedures involve the use of bioactive bone graft material and engineered proteins. See link http://www.straumann.us/us_index/pc_us_products/pc_us_regeneration/pc_us_emdogain.htm

Osseous Surgery

When nonsurgical therapy fails to give adequate results we often recommend osseous or flap surgery. This procedure has been around for quite awhile and is very effective. Of course, techniques have improved making this tried and true procedure even more effective and comfortable. We often incorporate the bone grafting procedures with this technique. Basically this involves moving the gums away from the roots, carefully inspecting and treating root surfaces; addressing bone defects and closing the gums with dissolving stitches. This is typically accomplished in our office with local anesthesia. Patients typically return to full activity the following day.

To learn more about osseous surgery please visit http://www.perio.org/consumer/pocket.htm

After numbing the area very well, an incision is made in the gum to separate the gum from the tooth. This "flap" allows us to access to the plaque calculus deep in the pocket.

The rough sharp edges of the bone can be smoothed off.

The gum is then repositioned around the neck of the tooth and held in place with sutures.

Ridge Preservation / Augmentation

Socket Grafting/Ridge Preservation

After a tooth is extracted, normal shrinkage of the bone will occur. The amount of shrinkage is unpredictable. Excessive shrinkage may prevent future placement of implants, create difficulty with your prosthesis, and compromise adjacent teeth or esthetics. It is common to place bone grafting materials into a socket immediately after extraction of a tooth or teeth in cases of multiple extractions. This will help maintain normal bone contours and significantly reduce the shrinkage of bone. The advantages are numerous and include: better implant base, support for adjacent teeth, improvement of aesthetics, and help improve fit and function of your prosthesis. Please ask our staff about this procedure.

Pre-Prosthetic Surgery

The preparation of your mouth before the placement of a prosthesis is referred to as pre-prosthetic surgery.

Some patients require minor oral surgical procedures before receiving a partial or complete denture, in order to ensure the maximum level of comfort. A denture sits on the bone ridge, so it is very important that the bone is the proper shape and size. If a tooth needs to be extracted, the underlying bone might be left sharp and uneven. For the best fit of a denture, the bone might need to be smoothed out or reshaped. Occasionally, excess bone would need to be removed prior to denture insertion.

One or more of the following procedures might need to be performed in order to prepare your mouth for a denture:

• bone smoothing and reshaping
• removal of excess bone
• bone ridge reduction
• removal of excess gum tissue
• exposure of impacted teeth

We will review your particular needs with you during your appointment.

Impacted Canines

Exposure and Bracketing of an Impacted Tooth

An impacted tooth simply means that it is “stuck” and can not erupt into function. Patients frequently develop problems with impacted third molar (wisdom) teeth. These teeth get “stuck” in the back of the jaw and can develop painful infections among a host of other problems. Since there is rarely a functional need for wisdom teeth, they are usually extracted if they develop problems. The maxillary cuspid (upper eye tooth) is the second most common tooth to become impacted. The cuspid tooth is a critical tooth in the dental arch and plays an important role in your “bite”. The cuspid teeth are very strong biting teeth which have the longest roots of any human teeth. They are designed to be the first teeth that touch when your jaws close together so they guide the rest of the teeth into the proper bite.

Normally, the maxillary cuspid teeth are the last of the “front” teeth to erupt into place. They usually come into place around age 13 and cause any space left between the upper front teeth to close tight together. If a cuspid tooth gets impacted, every effort is made to get it to erupt into its proper position in the dental arch. The techniques involved to aid eruption can be applied to any impacted tooth in the upper or lower jaw, but most commonly they are applied to the maxillary cuspid (upper eye) teeth. 60% of these impacted eye teeth are located on the palatal (roof of the mouth) side of the dental arch. The remaining impacted eye teeth are found in the middle of the supporting bone but stuck in an elevated position above the roots of the adjacent teeth or out to the facial side of the dental arch.

Early Recognition of Impacted Eye Teeth is the Key To Successful Treatment:

The older the patient, the more likely an impacted eye tooth will not erupt by nature's forces alone even if the space is available for the tooth to fit in the dental arch. The American Association of Orthodontists recommends that a panorex screening x-ray along with a dental examination be performed on all dental patients at around the age of 7 years to count the teeth and determine if there are problems with eruption of the adult teeth. It is important to determine whether all the adult teeth are present or are some adult teeth missing. Are there extra teeth present or unusual growths that are blocking the eruption of the eye tooth? Is there extreme crowding or too little space available causing an eruption problem with the eye tooth? This exam is usually performed by your general dentist or hygienist who will refer you to an orthodontist if a problem is identified. Treating such a problem may involve an orthodontist placing braces to open spaces to allow for proper eruption of the adult teeth. Treatment may also require a referral to an periodontist for extraction of over retained baby teeth and/or selected adult teeth that are blocking the eruption of the all important eye teeth. The periodontist will also need to remove any extra teeth (supernumerary teeth) or growths that are blocking eruption of any of the adult teeth. If the eruption path is cleared and the space is opened up by age 11 or 12, there is a good chance the impacted eye tooth will erupt with nature's help alone. If the eye tooth is allowed to develop too much (age 13-14), the impacted eye tooth will not erupt by itself even with the space cleared for its eruption. If the patient is too old (over 40), there is a much higher chance the tooth will be fused in position. In these cases the tooth will not budge despite all the efforts of the orthodontist and periodontist to erupt it into place. Sadly, the only option at this point is to extract the impacted tooth and consider an alternate treatment to replace it in the dental arch (crown on a dental implant or a fixed bridge).

What Happens if the Eye Tooth Will Not Erupt When Proper Space is Available?

In cases where the eye teeth will not erupt spontaneously, the orthodontist and periodontist work together to get these unerupted eye teeth to erupt. Each case must be evaluated on an individual basis but treatment will usually involve a combined effort between the orthodontist and the periodontist. The most common scenario will call for the orthodontist to place braces on the teeth (at least the upper arch). A space will be opened to provide room for the impacted tooth to be moved into its proper position in the dental arch. If the baby eye tooth has not fallen out already, it is usually left in place until the space for the adult eye tooth is ready. Once the space is ready, the orthodontist will refer the patient to the periodontist to have the impacted eye tooth exposed and bracketed.

In a simple surgical procedure performed in the surgeon's office, the gum on top of the impacted tooth will be lifted up to expose the hidden tooth underneath. If there is a baby tooth present, it will be removed at the same time. Once the tooth is exposed, the periodontist will bond an orthodontic bracket to the exposed tooth. The bracket will have a miniature gold chain attached to it. The periodontist will guide the chain back to the orthodontic arch wire where it will be temporarily attached. Sometimes the surgeon will leave the exposed impacted tooth completely uncovered by suturing the gum up high above the tooth or making a window in the gum covering the tooth (on selected cases located on the roof of the mouth). Most of the time, the gum will be returned to its original location and sutured back with only the chain remaining visible as it exits a small hole in the gum.

Shortly after surgery (1-14 days) the patient will return to the orthodontist. A rubber band will be attached to the chain to put a light eruptive pulling force on the impacted tooth. This will begin the process of moving the tooth into its proper place in the dental arch. This is a carefully controlled, slow process that may take up to a full year to complete. Remember, the goal is to erupt the impacted tooth and not to extract it! Once the tooth is moved into the arch in its final position, the gum around it will be evaluated to make sure it is sufficiently strong and healthy to last for a lifetime of chewing and tooth brushing. In some circumstances, especially those where the tooth had to be moved a long distance, there may be some minor “gum surgery” required to add bulk to the gum tissue over the relocated tooth so it remains healthy during normal function. Your dentist or orthodontist will explain this situation to you if it applies to your specific situation.

These basic principals can be adapted to apply to any impacted tooth in the mouth. It is not that uncommon for both of the maxillary cuspids to be impacted. In these cases, the space in the dental arch form will be prepared on both sides at once. When the orthodontist is ready, the surgeon will expose and bracket both teeth in the same visit so the patient only has to heal from surgery once. Because the anterior teeth (incisors and cuspids) and the bicuspid teeth are small and have single roots, they are easier to erupt if they get impacted than the posterior molar teeth. The molar teeth are much bigger teeth and have multiple roots making them more difficult to move. The orthodontic maneuvers needed to manipulate an impacted molar tooth can be more complicated because of their location in the back of the dental arch.

Recent studies have revealed that with early identification of impacted eye teeth (or any other impacted tooth other than wisdom teeth), treatment should be initiated at a younger age. Once the general dentist or hygienist identifies a potential eruption problem, the patient should be referred to the orthodontist for early evaluation. In some cases the patient will be sent to the periodontist before braces are even applied to the teeth. As mentioned earlier, the surgeon will be asked to remove over retained baby teeth and/or selected adult teeth. He will also remove any extra teeth or growths that are blocking eruption of the developing adult teeth. Finally, he may be asked to simply expose an impacted eye tooth without attaching a bracket and chain to it. In reality, this is an easier surgical procedure to perform than having to expose and bracket the impacted tooth. This will encourage some eruption to occur before the tooth becomes totally impacted (stuck). By the time the patient is at the proper age for the orthodontist to apply braces to the dental arch, the eye tooth will have erupted enough that the orthodontist can bond a bracket to it and move it into place without needing to force its eruption. In the long run, this saves time for the patient and means less time in braces (always a plus for any patient!).

Oral Pathology

The inside of the mouth is normally lined with a special type of skin (mucosa) that is smooth and coral pink in color. Any alteration in this appearance could be a warning sign for a pathological process. The most serious of these is oral cancer. The following can be signs at the beginning of a pathologic process or cancerous growth:

• Reddish patches (erythroplasia) or whitish patches (leukoplakia) in the mouth.
• A sore that fails to heal and bleeds easily
• A lump or thickening on the skin lining the inside of the mouth
• Chronic sore throat or hoarseness
• Difficulty in chewing or swallowing

These changes can be detected on the lips, cheeks, palate, and gum tissue around the teeth, tongue, face, and/or neck. Pain does not always occur with pathology and, curiously, is not often associated with oral cancer. However, any patient with facial and/or oral pain without an obvious cause or reason may also be at risk for oral cancer. We would recommend performing an oral cancer self-examination monthly and remember that your mouth is one of your body's most important warning systems. Do not ignore suspicious lumps or sores. Please contact us so we may help.

Our office provides Oral Cancer Screenings at every maintenance appointment. We are concerned about your overall health and do everything within our power to help you continue to be healthy. If anything is found during our Intraoral and Extraoral Tissue Exam, our doctors will evaluate it and determine the best next step.

We are equipped to do two different kinds of biopsies, if necessary, to determine the nature of a lesion or sore. Brush biopsy – a painless procedure, done in the office which can test common, harmless-looking, unexplained red and white spots. Incisional biopsy – a more traditional removal of cells and tissue to be sent to a lab for inspection.
