Single-tooth implants can be used in individuals who are missing out on one or more teeth. An implant is surgically put in an opening that your dental practitioner makes in the jawbone. After the implant incorporates (attaches) to your bone, it serves as a new “root” for the crown that will replace your missing tooth. A crown (cap), which is made to appear like a natural tooth, is attached to the implant and fills the area left in the mouth by the missing tooth.
Understanding of Dental Implants Procedure
For this procedure to work, there should be enough bone in the jaw. The bone has to be strong enough to hold and support the implant. If there is not enough bone, it might have to be included with a procedure called bone enhancement or bone grafting. In addition, natural teeth and supporting tissues near where the implant will be placed need to remain in health.
How Do Dental Implants Work?
An implant-restored tooth consists of a number of parts.
- The implant, which is made of titanium, is positioned in the upper or lower jawbone.
- The abutment can be made of titanium, gold or porcelain. It is connected to the implant with a screw. This part links the implant to the crown. It is formed like a natural tooth that has been lowered to get a crown.
- The repair (the part that appears like a tooth) is a crown. It usually is made of porcelain merged to a metal alloy (PFM). It also can be all metal or all porcelain. The crown is screwed or sealed onto the abutment. If the crown is screwed to the abutment, the screw hole will be covered with corrective material such as tooth-colored filling material (composite).
The Implant Process
The time frame for completing the implant and crown depends on numerous factors. When the traditional method of putting an implant is used, the shortest amount of time for a complete implant is about five months in the lower jaw and six months in the upper jaw. This consists of surgeries and positioning the irreversible crown. However, the process can last a year or more, especially if bone needs to be developed first.
In another method, implants and healing caps are placed at the very same time. If the dental expert is utilizing tiny implants, she or he will place them as well as the crown, bridge or denture at the same check out.
In the conventional method, two treatments are required, with three to 6 months between them. During the first procedure, a small cut is made in the gum where the implant will be positioned. A hole is drilled in the bone, the implant is placed into the hole in the bone, and the incision is sewn closed.
At the end of the recovery period, a 2nd procedure occurs. It involves making a brand-new cut to expose the implant. A collar, called a recovery cap, is screwed onto the top of the implant. It assists the surrounding gum tissue to recover. After a few weeks, the recovery cap is gotten rid of. The abutment is screwed into the implant and used to support the crown.
A one-stage procedure is now used sometimes for implants. In this procedure, your dental practitioner can place the implants, abutments and a temporary crown or bridge all in one visit.
Before any work is done, you will visit either a professional called a prosthodontist or a general dental practitioner who has had actually advanced training in the positioning and repair of implants.
Your dentist will do a comprehensive evaluation. During the exam, he or she will evaluate your medical and dental history, take X-rays, and produce impressions of your teeth and gums so that designs can be made. Sometimes, the dental expert likewise may purchase a computed tomography (CT) scan of your mouth. This scan will assist your dentist identify how much jawbone is readily available to hold the implants in location. It likewise will reveal the location of structures such as nerves and sinuses (located above your upper teeth) so they can be avoided during surgery.
If the X-rays show that your jaw does not have adequate bone to hold an implant, the dental expert can discuss options for building up the bone. These may consist of bone grafting or bone interruption. Grafting includes taking bone from another source and adding it to your jaw. A graft could be your own bone, from your mouth, chin or hip. Processed cadaver, cow or pig bone also can be used. Another option is an artificial product such as hydroxyapatite or calcium phosphate. Bone diversion is a surgery at the site where more bone is needed. It causes the body to grow more bone by gradually pulling apart the existing bone utilizing pins and screws.
If you need one of these treatments, it will take about 4 to 12 months for the bone to be all set for the implant.
First surgery – implant placement:
- Month 1 (if no bone grafting is necessary).
- Month 5 (if bone grafting is necessary).
When you have enough bone to effectively hold an implant, you will schedule the first procedure, which involves positioning the implant or implants in your jaw. A periodontist, oral surgeon or basic dental practitioner with training in implantology performs this procedure. It is done using a plastic surgical guide made by your prosthodontist or general dental practitioner. The guide fits over your existing teeth and crosses the area where teeth are missing out on to show where the implants have to be put.
The most popular type is a root-form implant developed to function as the root of the tooth. The implant is placed in the jawbone in the space produced by the missing tooth.
After the first surgery, the professional will wait four or 5 months if implants were put in the lower jaw, and six or 7 months if they were positioned in the upper jaw. During this time, the bone and the implants fuse.
Second surgery and positioning of healing collar and/or temporary crown:
- Month 4 or 5 (no bone grafting, lower jaw).
- Month 6 or 7 (no bone grafting, upper jaw).
- Month 8 or 9 (bone grafting, lower jaw).
- Month 10 or 11 (bone grafting, upper jaw).
As soon as the implants have actually ended up being merged with the bone, you can schedule the second surgery. Your dental professional will confirm whether the implant is prepared for the second surgery by taking an X-ray. This surgery is easier than the first. A new cut is made to expose the heads (tops) of the implants.
A collar, called a recovery cap, is put on the head of the implant after it is exposed. This guides the gum tissue to heal properly. The collar is a round piece of metal that holds the gum away from the head of the implant. (A) The collar will remain in place for 10 to 14 days. If you previously had a detachable partial denture, your dentist might change it so you can use it during this time.
After the tissue heals around the collar, it is gotten rid of. (B) Then an abutment is screwed into the implant and a last impression is made of the abutment for each tooth.
An abutment and temporary crown are put on the implant. (C) The abutment is screwed onto the implant and tightened, utilizing unique devices so that it won’t come loose. After the abutment is connected to the implant, the temporary crown is placed on the abutment. In many cases, you might get the abutment and temporary crown right away after the implants are uncovered during the 2nd surgery, and you will not require a healing cap.
The temporary crown will remain in location for four to 6 weeks. The gums will heal around it and will look like the gums around your natural teeth. The temporary crown is made of softer product than the irreversible crown. The softer material assists to cushion and secure the implant from the pressure of chewing, and gives the jawbone the chance to slowly get more powerful.
Placement of permanent crown:
- Month 5, 6 or 7 (no bone grafting, lower jaw).
- Month 7, 8 or 9 (no bone grafting, upper jaw).
- Month 9, 10 or 11 (bone grafting, lower jaw).
- Month 11, 12 or 13 (bone grafting, upper jaw).
While you are using your temporary crown, the irreversible crown will be made. It may take 2 to 3 weeks, or less, to make a permanent crown. The crown can be created from a design of your teeth and gum tissue that consists of the abutment.
The crown can be either cemented or screwed to the abutment.
Crowns held in location by cement might look better due to the fact that there is no screw hole in the crown to be seen. Nevertheless, crowns held in location by a screw are easier for your dental expert to get rid of if she or he has to reach the implant or the tissue around the implant.
Caring for Your Implants
You look after your implants the exact same way you care for your natural teeth. It is important to brush and floss daily. If you have any problems, see your dentist prior to your 6- month recall see.
What Will X-Rays Show?
On an X-ray, you will be able to see the implant in the bone, the abutment and the crown. Your dentist can look at how the implant, abutment and crown mesh and make certain that there are no issues.
In addition to the risks of surgery, there is the possibility of the implant stopping working. An implant can stop working if an infection develops, which is unusual, or if the bite (the way the teeth come together) has actually not been properly adjusted. In addition, clenching or grinding teeth can put a lot of pressure on the implant. This might cause bone loss, and cause the implant to break or fail.
You need to know that when implants are used to replace lower teeth, a nerve that runs through the jawbone often can be injured when the bone is being drilled or the implant is being put. This can cause numbness or tingling. If this happens, it normally includes the lower part of the lip and chin or one side of the tongue. The numbness can be temporary, till the nerve heals, or it can be long-term. Nevertheless, it is not common for the nerve to be hurt. X-rays and computed tomography (CT) scans can help your dental professional to see where the nerve is located and lessen the possibility of hurting the nerve.
In the upper jaw, there is a risk of drilling through the jawbone into one of your sinuses (located above your upper teeth) or nasal cavity, which might cause an infection. To prevent this, special X-rays are taken prior to your surgery to assist your cosmetic surgeon to figure out where your nerves and sinuses lie.
What Can You Expect From Your Implant?
Single-tooth implants will work and appear like your natural teeth. However, for some patients, it will be challenging to make the implant look exactly like your natural teeth. In many cases, your implant will not be positioned straight, but will be placed on an angle in the bone because of the quantity of bone that you have and the amount of bone that is had to put the implant correctly.
A crown can be made broader to close an area. Research studies up until now have revealed that these implants can last as long as 25 years.
