Snacking on 1/4 cup of peanuts 3 or 4 times a week may help adults lose weight and prevent obesity in children and adolescents. How Weight Loss Can Change Your Life. When you want to lose weight, Virtua helps you feel your best while helping you set sensible, achievable goals. Feline weight loss, when unplanned, is something to be concerned about at any age. Unfortunately, a cat losing weight is often a sick cat, and this key cat illness. Effects of Tooth Loss . However, the more teeth a patient is missing, the more difficult this goal becomes with traditional dentistry. As a result of continued implant research and the advances in implant techniques, predictable success is now a reality for the rehabilitation of many challenging patient situations. As our population ages this success becomes critically important in order to preserve the health of the population.
Life expectancy has increased significantly past the age of retirement. In 1. 96. 5, the average life span was 6. A person 6. 5 years old, can now expect to live 1. This increased life expectancy has led to increased tooth loss. Currently, 2. 6% of all Americans over the age of 6. Social pleasures, including dining and dating, are diminished when the teeth are lost. Almost 3. 0% of the employed or retired adult US population is either missing all their teeth, all their upper teeth, one entire posterior segment (a full quarter of the mouth) or has all of their back teeth missing. A study by CW Douglas published in J. Conditions of tooth loss were treated with removable replacement teeth, called full or partial dentures. Today, the full scope of dental services for elderly patients is becoming increasingly important to both the public and the profession, because of the increasing age of our society. Alternative treatment designs, which include methods to reconstruct teeth on top of implants and that are not removable, should be presented to almost every patient. Only when all treatment options are discussed can a persons desires related to the benefit of modern dentistry be truly appreciated. Eventually, the need for additional retention, support, and stability, or the desire to eliminate a removable denture, are common indications for more effective and permanent solutions, such as dental implants. Dental implants, which are man- made tooth root replacements, are also increasingly used to replace a missing single tooth. Like natural tooth roots, they can be used to support permanent types of tooth replacements, or act as anchors for a removable prosthesis to replace teeth (i. Today, this represents the most conservative and most predictable long- term option. Traditional dentistry most often replaces the missing single tooth with a fixed bridge. This is accomplished by grinding away sound tooth structure, and crowning (capping) two or more teeth on each side of the missing tooth and joins them together with the artificial or dummy tooth. This approach increases the risk of decay of the crowned teeth, increases the risk of root canal therapy, and makes oral hygiene difficult to impossible, which in turn increases bacterial plaque retention (the cause of decay and gum disease). Today's technology can replace the tooth with a dental implant, which may replace a single tooth or a whole mouth of teeth, without crowning any teeth. One of the major benefits is that the remaining teeth are easier to clean and less likely to decay, and/or need root canal therapy. The average dental implant has a better long- term survival rate than the average bridge. The average bridge gets replaced every 8 to 1. Consequences of Tooth Loss. Effect on the Jaw Bone. The bone in the body acts very similar to a muscle. When muscles are exercised, they grow strong and larger. When bone is exercised or stimulated, it also becomes stronger. For example, when an arm is broken and placed in a cast for six weeks, you can see the arm is smaller after this time frame, since the muscles have started to shrink or atrophy. In addition, if you evaluate the bone protected by the cast, it also becomes less dense and weaker in this period. Similarly, the bone of the jaw can only be stimulated by a tooth or by an implant. The connections between a tooth, or an implant, create and preserve the size and shape of the bone. Bone needs the stimulation of the tooth roots to maintain its form, density, and strength. Scientific studies have proven that the normal chewing forces that are transmitted from the teeth to the bone of the jaw are what preserves the bone and keeps it strong. In this photo, it is easy to see how the ridge has collapsed. The tooth was removed and, without stimulation or grafting, the bone and gum have disappeared. This close relationship between the tooth and the bone continues throughout life. When a tooth is lost, the lack of stimulation to the surrounding bone results in a decrease in the density and dimensions of the bone. This means that there is a loss of width and height of the bone. In a 2. 5- year study of patients with no teeth, x- rays demonstrated continued bone loss of the jaws during this entire time span. Therefore, a tooth is necessary both to the development of the bone around the tooth, and is also necessary for the stimulation of this bone to maintain its strength, density and shape. The loss of all of the teeth slowly, but eventually, leads to jaws with almost complete bone loss. A lower jaw, which starts out two inches in height, can be reduced to less than one- quarter of an inch by atrophy over time. That is one reason why modern dentistry is so excited about using dental implants to replace missing teeth. Patients wearing dentures dont realize they are losing bone. Over time, the poor fit and function of the denture is often thought to be due to its age, weight loss by the patient, or wear of the dentures teeth. The rate and amount of bone loss may be influenced by gender (females lose more bone), hormones (lack of estrogen causes more bone loss), metabolism, medications, parafunction (grinding the teeth) and poorly fitting dentures. Despite this, almost 4. Although the fact that wearing dentures day and night places greater forces on the bone and gum, and accelerates bone loss, 8. Consider the following: The issue of bone loss after tooth loss has been ignored in the past by traditional dentistry. This is so because dentistry had no treatment to stop or prevent the process of bone loss and its consequences. As a result, doctors had to ignore the inevitable bone loss after tooth extraction. Today, the profession knows about bone loss, and that implants can stop bone loss because they stimulate the bone, similar to the way the tooth did prior to its loss. Jaws with bone loss are associated with problems, which often impair the predictable results of traditional dentures. The loss of bone first results in decreased bone width. There is a 2. 5% decrease in width of bone during the first year after tooth loss and an overall . The remaining narrow bone often causes discomfort when the thin overlying gum tissues are loaded under a complete or partial denture. In the lower jaw, the continued bone loss eventually results in prominent bony projections covered by thin, movable, unattached gum tissue. As the remaining bone on the front of the jaw continues to disappear, the bony projection under the tongue rises to sit on the top of ridge. This results in pain, as the denture sits atop the sharp bony projection. In addition, there is little to prevent the denture from moving forward against the lower lip during function or speech. The problems are further compounded by the upward movement of the back of the denture during contraction of the muscles during speech and function. The resulting incline (slope) of the now deformed lower jaw compared with that of the upper jaw also creates instability and movement of the lower denture. Loss of bone in the upper and lower jaw is not limited to the bone around the teeth; portions of the skeletal bone also may be lost especially in the back parts of the lower jaw where the patient may lose more than 8. The nerves of the lower jaw which were surrounded by and protected by bone eventually become exposed and sit on the top of the ridge directly under the denture. As a result, acute pain and/or temporary to permanent loss of sensation or feeling of the areas supplied by the nerve is possible. The bone loss in the upper jaw may cause pain and an increase in upper denture movement during eating. The forces from eating with an ill- fitting denture are transferred directly to the surface only and not the internal structure of the bone since there are no roots. Therefore, these forces do not stimulate and maintain the bone, but instead actually decrease blood supply and increased the rate of the bone loss. Chewing forces generated by short facial types can be 3 or 4 times that of long facial types. These patients are at even greater risk to develop severe bone loss. This photo shows a lower ridge that has lost 6. The black arrows indicate where bone is located (compare the width to the adjacent molar). The red arrows indicate the normal width that should be there. Many of these conditions that have been described for patients without any teeth also exist for patients where only back teeth are missing and they are wearing a removable partial denture. The above problems focus on the damage to the bone. The remaining natural teeth are also subjected to substantial damage. The teeth must support the partial denture by connections called clasps. The clasps grab onto the teeth, and by design, transfer lateral or sideward forces to the teeth, which weaken them and cause tooth loss. Since these teeth often become compromised by loss of bone due to these forces, many partial dentures are then designed to minimize the forces applied upon these teeth. The net result is an increase in movement of the removable denture, and greater pressures on the soft gum tissue over the bone. This results in more bone loss. These conditions can protect the remaining teeth, but then accelerate the bone loss in the regions without teeth. Effect on Soft Tissue. As bone continues to lose width and height, the gum tissues gradually decrease. A very thin gum usually lies over the advanced bone loss of the lower jaw. The gum is prone to sore spots caused by the overlaying denture. In addition, unfavorable high muscle attachments and loose tissue often complicates the situation.
