Bone loss and dental implants

Posted Nov 07 2009 6:30am 1 Comment
Bones to Blame for Aging FaceThey shrink as years go by, and this process is faster in women, study finds
SUNDAY, Sept. 25 (HealthDay News) -- Beauty, and age, is more than skin deep. In fact, it's bone-deep, a new study finds.
Researchers say shrinking facial bones play a major role in facial aging and that women experience this type of facial bone loss at a younger age than men.
"Many people believe that only gravity creates wrinkles; however, we have discovered the loss of volume in the face and changes in bone structure also contribute to making us look older," study co-author Dr. David Kahn said in a prepared statement.
"As we age, not only do we lose fat in our faces but our bones actually change in contour, often making us look older than we feel," Kahn said.
The findings were presented Sunday at a conference of the American Society of Plastic Surgeons in Chicago.
Kahn's team analyzed computed tomography scans of 30 women and 30 men ranging in age from 25 to more than 65 years old.
He and his colleagues found that, as individuals age, their facial bones dissolve, shrink and leave empty spaces. Since skin also loses elasticity as we age, it's not able to tighten around the spaces left by facial bone loss. Thus, we end up with drooping and wrinkles.
Kahn said the fact that women tend to experience facial bone loss at a younger age than men may explain why women are more likely to seek facial cosmetic enhancement at a younger age than men.
Dr. Tanya Long at 4th Street Dental Spa in Louisville Kentucky can help stop bone loss from missing teeth with the insertion of mini dental implants. Miniaturized implants for denture stabilization is one of the fastest growing segments in the dental product industry.Mini implants are frequently used for single tooth replacements and in crown and bridge cases. A popular and most effective use of this technology is stabilization of the lower denture.These devices represent a very efficient solution for denture wearers who have experienced extreme discomfort due to loose and ill fitting dentures. Problems associated with trapped food particles, "denture breath" and common social issues are virtually eliminated.Unlike traditional implant dentistry, mini's are installed without complicated surgery. Since healthy bone is selected, the need for bone grafts is eliminated in most cases. Complete treatment and fitting can be completed in just a couple of hours by a trained doctor.

Jawbone Resorption Analysis

Bone Loss DetectionVirtual ImagingBone density problems can occur in both the Maxilla (upper jaw) and Mandible (lower jaw) for a number of reasons. A condition that becomes more prevalent as we age, it is a complicated and serious issue that many patients don't understand well.Healthy jawbone structures are required for the retention of teeth and for maintaining good oral health. Periodontal disease is only one of several conditions that will, if left untreated, will slowly attack and destroy otherwise healthy bone tissues.
The Knowledgeable FewMost of the intricacies and important things to know about bone density don't gain most people's attention however, until they actually have it. Bone density problems involving internal resorption and rapid bone deterioration begins almost immediately.... depending upon what treatments a patient has received. It is this patient group that unfortunately becomes knowlegeable, after the fact, about the relationship between sensible, informed dental treatment and jawbone preservation.
Jawbone Integrity - Understanding Bone StimulationNatural teeth are attached to our jawbones via a root structure. Depending on the location and size of any given tooth, these root structures will vary in size, depth and complexity. The behaviors of biting and chewing (forces of mastication) produce physical stimulation of each and every root structure which in turn stimulates the immediate bone material that the root is attached to. As long as we have our natural teeth and the absence of any disease process, our mandibular (lower jaw) and maxillary (upper jaw) bone structures can be expected to remain healthy and intact.
Common Causes of Jawbone DeteriorationNumerous events, oral disease, dental conditions and a patient's history of dental treatments can compromise important jawbone characteristics. Some of the more common causes are listed here:
Trauma: Events that cause a tooth to be knocked out or broken off to the extent that no biting surface exists (such as broken off at the gum line), bone stimulation ceases.
Extractions: As soon as an adult tooth is removed, and not replaced, bone stimulation ceases for that particular site.
Dentures: Low cost, unanchored dentures are designed to ride or rest on top of gum tissue. Contrary to what many people want to believe, there is no direct stimulation of jaw bone material. Rather, there may be accompanying loss of gum tissue while the all important underlying bone structure slowly resorbs.
Bridgework: Custom bridges are a popular treatment for replacing missing teeth. The bone structure underlying the span of missing teeth will undergo deterioration (only the anchoring teeth continue to provide important bone stimulation.
Gross Malalignment: Alignment issues due to growth factors, trauma and untreated extractions can cause situations where certain tooth structures do not have an opposing tooth structure. The unopposed tooth may super erupt and also undergo underlying bone deterioration.
Abnormalities in the Bite Occlusal Relationship: Dentists routinely maintain a close focus on bite and occlusion. Assessment of the biting surfaces assures normal bite characteristics, overall dental function and patient comfort. Long standing occlusal issues arising from lack of treatment, normal wear and tear and certain TMJ-TMD problems can cause abnormal physical forces that disrupt the balance of the occlusal relationship. When significant, bone deterioration can occur with certain tooth structures.
Advanced Gum Disease: Periodontitis, if left untreated, causes wholesale devastation of all tissues at the site of infection. Bone tissue, gingival tissue and connective tissue all undergo destructive changes that may or may not be fully restorable
Controlling or Stopping Jawbone Deterioration - ResorptionUsing the format outlined above describing different cause and effect relationships with bone loss, treatment suggestions are listed below:
Trauma: A combination of single or multiple implants is efficient... as is a fixed bridge.
Extractions: Depending on the site and need (e.g., wisdom versus anterior (front tooth) replacement of the root-jawbone stimulation is best restored via an implant.
Dentures: Edentulous patients should consider implant anchored dentures whenever possible, using the largest practical number of implants possible (2 is good, 4 is better, more than 4 better still.
Bridgework: Follow dentist's best recommendation for type, size and location.
Gross Malalignment: Alignment should be restored using whatever treatments are appropriate (orthodontics, tooth extractions, implants, onlays, etc).
Abnormalities in the Bite Occlusal Relationship: Sometimes difficult to treat without intensive study and use of articulators. Treatments might include new fillings, onlays, new crowns, bite appliances, night guards (treatment for bruxism and teeth clenching).
Advanced Gum Disease: Seek immediate treatment. Stopped and controlled early enough, a patient may have treatment choices that can restore a substantial percentage of function. Tissue grafting and specialized implants are possible in some cases.
Healthy Jawbone Structures - Maintaining The Natural Order of ThingsMother Nature developed a system of opposing physical forces that promotes optimal dental function and long term oral health. Chewing and eating behaviors (with normal occlusion) serve to stimulate the bone tissue and keep our jawbones healthy.Disruptions that occur, as outlined above, have the potential of altering the physical forces that science has proven to be essential.Jawbone integrity is best maintained by keeping a mindful eye on the physical forces that should be operating on each and every tooth in a patient's mouth.Implant Dentistry, now represented with a growing number of specialized treatments, products and specialized adaptations, has become one of the single most popular and most effective technologies for reinstating what Mother Nature originally provided.Combined with advanced bone grafting and specialized soft tissue grafts, doctors can virtually recreate lost tissues and use artificial root form implant devices (commonly known as dental implants) to take the place of natural teeth, thereby reestablishing the critical physical forces needed for maintaining good bone density.It is not uncommon for patients to experience a healthy reversal of the bone loss process that is so easily initiated by the factors mentioned above.
Severe Bone and Tissue Loss Treatment ExampleImplant reconstruction combined with custom fixed bridge and denture components is one example of how doctors can treat a serious bone, teeth and tissue loss problem for some patients.
Avoiding Recommended ExtractionsExtractions, for some patients who have already suffered extensive bone loss, should be avoided for some patients. Specialized attachment systems can be created by some doctors that can take advantage of healthy root systems of teeth that have deteriorated above the gum line.As a rule, although implants are an ideal technology (the Gold Standard of tooth replacement), healthy natural roots always surpass the value of an artifical (titanium implant) root.Treatment solutions do exist for many of the conditions described. Access to technologies and the degree of creative experience a doctor has accumulated determines the number of choices a patient can have for resolving certain bone issues in their oral health care needs.

Its a good post. I never know about shrinking of bones with growing age.

It has provided a good knowledge about dental implants and different concepts related to it. Thanks for the post.
