Dental Implants have changed the face of dentistry over the last 25 years. Let’s know, What are dental implants? And how are they used to replace missing teeth?
As with most treatment procedures in dentistry today, dental implants not only involve scientific discovery, research and understanding, but also application in clinical practice. The practice of implant dentistry requires expertise in planning, surgery and tooth restoration; it is as much about art and experience as it is about science.

What are the dental implants?
dental treatment of dental implant at jamnagarLet’s start from the beginning: A dental implant is actually a replacement for the root or roots of a tooth. Like tooth roots, dental implants are secured in the jawbone and are not visible once surgically placed. They are used to secure crowns (the parts of teeth seen in the mouth), bridgework or dentures by a variety of means. They are made of titanium, which is lightweight, strong and biocompatible, which means that it is not rejected by the body. Titanium and titanium alloys are the most widely used metals in both dental and other bone implants, such as orthopedic joint replacements. Dental implants have the highest success rate of any implanted surgical device.
Titanium’s special property of fusing to bone, called osseointegration (“osseo” – bone; “integration” – fusion or joining with), is the biological basis of dental implant success. That’s because when teeth are lost, the bone that supported those teeth is lost too. Placing dental implants stabilizes bone, preventing its loss. Along with replacing lost teeth, implants help maintain the jawbone’s shape and density. This means they also support the facial skeleton and, indirectly, the soft tissue structures — gum tissues, cheeks and lips. Dental implants help you eat, chew, smile, talk and look completely natural. This functionality imparts social, psychological and physical well-being.

Understanding Dental Implants by some Questions

1.      Can anybody be candidate for dental implants?
Generally speaking, if you have lost teeth you are a candidate for dental implants. It is important that you are in good health, however, as there are some conditions and diseases that can affect whether dental implants are right for you. For example, uncontrolled diabetes, cancer, radiation to the jaws, smoking, alcoholism, or uncontrolled periodontal (gum) disease may affect whether dental implants will fuse to your bone. It is important to know all about your medical status (past and present) together with all medications you are taking, whether prescribed, alternative (herbal) or over-the-counter.
Where and how implants are placed requires a detailed assessment of your overall stomato-gnathic system (“stoma” – mouth; “gnathic” – jaws), within which the teeth function. This will necessitate compiling records that include study models of your mouth and bite, and specialized radiographs (x-rays), which may include 3D scans known as computerized tomograms (CT scans). Planning with the help of computer imaging ensures that dental implants can be placed in exactly the right position in the bone.

2.      How and why is bone lost when teeth are lost?
Bone needs stimulation to maintain its form and density. In the case of alveolar (sac-like) bone that surrounds and supports teeth, the necessary stimulation comes from the teeth themselves. When a tooth is lost, the lack of stimulation causes loss of alveolar bone. There is a 25% decrease in width of bone during the first year after tooth loss and an overall decrease in height over the next few years.
The more teeth lost, the more function lost. This leads to some particularly serious aesthetic and functional problems, particularly in people who have lost all of their teeth. And it doesn’t stop there. After alveolar bone is lost, the bone beneath it, basal bone — the jawbone proper — also begins to resorb (melt away).

3.      How can bone be preserved or re-grown to support dental implants?
Grafting bone into the extraction sockets at the time of tooth loss or removal can help preserve bone volume needed for implant placement. Surgical techniques are also available to regenerate (re-grow) bone that has been lost, to provide the necessary bone substance for anchoring implants. In fact, a primary reason to consider dental implants to replace missing teeth is the maintenance of jawbone.
Bone needs stimulation to stay healthy. Because dental implants fuse to the bone, they stabilize it and prevent further bone loss. Resorption is a normal and inevitable process in which bone is lost when it is no longer supporting or connected to teeth. Only dental implants can stop this process and preserve the bone.

4.      How are dental implants placed and who places them?
It takes a dental team to assess and plan dental implant placement and restoration — the fabrication of the crowns, bridgework or dentures that attach atop the implants and are visible in your mouth. The dental team consists of a dental surgical specialist — a periodontist, oral surgeon, or a general dentist with advanced training in implant surgery; a restorative dentist, who plans and places the tooth restorations; and a dental laboratory technician who fabricates them.
Placing dental implants requires a surgical procedure in which precision channels are created in the jawbone, often using a surgical guide. The implants are then fitted into the sites so that they are in intimate contact with the bone. They generally require two to six months to fuse to the bone before they can have tooth restorations attached to them to complete the process.

5.      What are the options for implant tooth replacement?

·       Single Tooth Replacement:

This is a device that “abuts” or joins the implant to a tooth form called a crown, which replaces the tooth part you see in the mouth. It will hold a custom-made crown that the dental laboratory will fabricate and match to your existing teeth. The custom crown is cemented or screwed onto the abutment to permanently keep it in place. Once the crown is in place, it should be indistinguishable from your natural teeth.

·       Fixed Multiple Tooth Replacement:

After healing, permanent abutments are attached to the implants. They can attach to custom-made crowns or bridgework that a dental laboratory will fabricate to match your existing teeth. In the final step, the custom bridge, which will replace multiple teeth, is cemented or screwed onto the abutments. The teeth have been replaced without disturbing the healthy teeth next to them, and bone loss has been halted.

·       Removable Implant-Supported Tooth Replacement:

If all of your upper teeth are missing, a minimum of four implants may be used to support an upper denture. Removable dentures are often used to replace extensive tooth, bone and gum-tissue loss, thus providing support for the facial skeleton, lip and cheeks. A new denture can have attachments that snap or clip it into place on the implants or a custom made, milled bar can be fabricated to create additional strength and support for the restoration. Design variations are often related to your bone density and number of implants present; your dentist will discuss these options during your consultation. A significant advantage of a removable denture is facilitating the cleaning of the dental implants.

6.      How do implant tooth replacements differ from teeth?
jamnagar dentist, dentist jamnagar, implantologist jamnagar, advantage of implantNatural teeth and dental implants may look the same, feel the same, and even function in a similar way, but they are very different. The most important differences are in the way they attach to the surrounding bone, their response to dental disease, their maintenance, and repair.
Teeth attach to the surrounding bone by a periodontal ligament (“peri” – around; “dont” – tooth) made up of collagen fibers that join into the tooth on one side and bone on the other. Dental implants fuse directly to the bone.
The gum tissues also attach to the root of a tooth with collagen fibers as described above. However, gum tissues can only stick to the surface of dental implants.
Teeth are susceptible to dental decay as well as the need for root canal therapy; dental implants are metal and do not decay or need root canal. Teeth may also be susceptible to periodontal (gum) disease, while dental implants may be susceptible to peri-implantitis, an inflammatory response to bacterial biofilm of the tissues surrounding the implant, which can result in disintegration of the bone to the implant.

7.      What type of maintenance do dental implants require?
Implant crowns and other prosthetic (false) tooth replacements are made to be remarkably failsafe systems. They are removable and replaceable (only by your dentist), so that if damage or wear necessitates replacement, this can be accomplished without affecting the implant(s) or attachment to the bone.
Nevertheless, implants do require maintenance. It is important to practice good daily oral hygiene, including brushing and flossing to control bacterial biofilm. It is also important to see your dentist.

8.                  How much do dental implants cost?
Dental implants are not cheap but they are a good alternative to dentures or a bridge and they enjoy a high success rate. They also result in natural looking teeth that will last for years as well as improving individual self-confidence. The vast majority of patients report high satisfaction levels with their implants. A common question by some of the patient is  “How much does a dental implant cost?”  The  answer: It depends. Costs of treatment do vary which is a result of the different fees charged by dentists, plus the type of implant used. If you require bone grafting because your jawbone is not deep or wide enough then this will increase the price even more.
There are so many variables to consider that answering this over without clinical examination and investigation.  Some things to consider include:
§  How many teeth are missing?
§  How long have the teeth been missing?
§  How many will be replaced?
§  What kind of provisional restoration will be used?
§  What kind of bone is present?
§  Are sinuses an issue?
§  How close are adjacent teeth?
§  Is the lower nerve in the way?
§  How thick and wide is the bone where the implant will go?
§  How soon must the treatment be done?
§  Will the restoration stay in the mouth or will it be removable?

The three main parts to consider with dental implants are the titanium implant, the restoration and the connector (abutment) that connects the restoration to the implant.  All three part’s cost depend upon it’s design according to type of use.

o   Missing teeth
maxillary implant, jamnagar, implant, jamnagar dental, implantologist at jamnagar, fix teeth dental treatmentThe procedure for replacing a single missing tooth is much less complex than when many teeth are missing. When two or three teeth are missing, 2-3 implants can support a bridge and a smile is complete. If an entire arch of teeth is missing, then many implants should be placed to support a variety of options of restorations. Rule of thumb is to have 8-10 implants on the upper arch, 6-8 implants on the lower arch.

o   Length of time missing teeth
long time after extraction, loss of with of bone for implantWhen teeth are lost, the remaining bone changes. Over time, the volume of bone shrinks, so if a person desires an implant later in life, extra steps may be needed. A common procedure is a bone graft. This increases bone volume, allowing placement of a dental implant, but can add both time and expense to the treatment plan.  

o   Temporary restorations
While the implant is placed, we must wait for the bone to fuse to the implant (osseointegration). During this healing time, there are choices. One can simply live with a space, or a temporary restoration can be placed. Temporaries can be screwed in place (removed only by the dentist) or removable, like an orthodontic retainer.

o   Bone quality
Dense bone is more stable than porous bone. Different areas of the
mouth have different densities, so the type of implant and method of surgical placement is influenced by where the implant is placed.  

o   Sinuses
When placing upper jaw posterior implants, location of the sinus is a factor. Over time, the sinus floor can descend (pneumatization) and become a problem if an implant is desired. A sinus lift is commonly performed to create room for an implant. 

o   Space between teeth

o   Lower jaw nerve
risk of damage inferior alveolar nerveThe inferior alveolar nerve is problematic for lower posterior teeth. Ideally implants are very long, but the location of the nerve may not allow long implants to be placed. Options may include repositioning the nerve, using a shorter implant, or using an angled implant to go around the obstacle. 

o   Bone thickness
less width for implant make it difficult to place dental implantDental implants need to be completely “immersed” in bone for stability. This means if the thickness of bone is 3 mm wide, a 5 mm implant is too big. In gardening, potted plants can go from small pots to larger pots, but not the other way around. If the bone is not thick enough, a bone graft may be an option.   

o   Time frame
One unavoidable drawback with dental implants is time. Osseointegration (bone fusing to the implant) takes 3-6 months before a final restoration can be placed. Often temporary (provisional) restorations appear like final restorations and can be worn for extended periods of time to help mitigate frustration, but some things can’t be avoided. If the goal is to be done in a single visit, dental implant treatment may not be the best treatment option.
