In the field of dentistry, dental implants are used to resemble the natural tooth root. Typically these structures are made from titanium and work by supporting tooth restorations. Examples of prostheses used with implants: bridges, dentures and crowns.

In general, implants are constructed with pure titanium. They include screws that are designed to mimic the natural root of a tooth. A rough or smooth surface can be obtained by techniques such as etching, plasma spraying, sandblasting, and anodizing.

These structures must be placed using surgery. Prior to performing the surgery, a dentist may advise that other tests and procedures be performed. Radiographs may be done pre-surgery to assess the dimensions, shapes and structures of a mouth. This step is important to the overall process because it assures that the implants are the correct sized and properly oriented. CT scans may also be required before the surgery. Stents may be set up for surgeons to use as a guide during implant placement.

During the actual surgery, the bone will be prepped using hand osteotomes or precision drills, both of which have speed-regulation functions to prevent pressure necrosis. It is integral that osseointegration, the bone growing to the top of the implant, occurs before any type of restoration is placed. This duration of this process depends upon the overall quality and quantity of bone.

It is common for most dentists to wait up to six months for the mouth to fully heal. This healing time will vary considerable. However, if a restoration is installed too soon after the initial surgery, the implant can fail. In some cases an implant can take up to a year to fully heal. The estimated success rate for this procedure is at 95 percent. With that said, quality and quantity of bone, oral hygiene, surgeon skill, and post-surgery maintenance all impact outcome. Most failures are the result of osseointegration not occurring.

The jawbone plays an important role in the outcome of this procedure. It must have enough strength and mass to support the implant. If not, a technique called the graft procedure may help. As is true of any surgery, complications may arise. Infection of the area can occur, and if the body identifies the implant as foreign, it will reject it. Other potential complications: periodontal disease, incision point opening, inflammation and fixtures falling out. Read more… »

Dental implants are a device used in the field of dentistry to support replacements that look like a tooth or a group of teeth so as to replace missing teeth. Usually they resemble the root of the tooth and are placed within the bone of the jaw. It is made of titanium and after the procedure the implants will fuse with the bone but they will feel different from the natural teeth.

Before the root device came alone there were the blade devices. This involved a flat metal piece being placed within the bone. The piece is made to lie upon the gum and attached with screws to the jaw bone. Dental implants are useful in supporting dental attachments such as crowns or dentures. They also anchor orthodontic tooth movement as well as permitting unidirectional tooth movement without it reciprocating.

The basic implant is made from a titanium or alloy titanium screw. Its surface could be rough or smooth and modified through various methods to increase the surface area. Through this its potential to fuse with the bone is also increased.

The surgical planning is done on the mouth to identify the biological properties of the tooth and the jaw bone to properly arrange the implants to define the most appropriate outcome. A surgical stent may also be used which fits over the teeth or the bone surface with holes that show where the implants are to be positioned.

The basic procedure involves the placement of the implant. Some time is allowed to let the bone grow on the titanium surface after which the crown is placed. The procedure must be performed carefully to ensure vital structures in the jaw and the bone are not damaged.

There are some points to be considered before the procedure is done. The bone has to be strong and in plenty to hold and support the device. Otherwise grafting may be performed to add to the bone. The teeth and tissues around the device must also be in good shape. The loading forces to be exerted on the device should be considered to avoid its failure. Read more… »

Having dental implants inserted is an alternative to wearing false teeth, commonly known as dentures. For those who are missing one or more teeth, an implant will add confidence by improving your smile and will make eating much easier. Having implant surgery is a complex process which will require several visits with a specialist.

When going in for your initial examination, the dentist will take x-rays of the mouth in order to get a thorough evaluation. Always be sure you tell the dentist about any existing medical condition you have. It’s important that they are aware of any medications or health problems prior to having implant surgery.

The dentist will explain your implant procedure with you carefully. At this time be certain to ask any questions or go over any concerns that you may have. It’s important that you will know exactly what to expect regarding the surgery itself and the outcomes.

As with any other surgical procedure, you will be asked to quit smoking and reduce consumption of alcohol beforehand. These can be very detrimental to your health with the possibility of leading to an implant procedure which fails. Also, the dentist will instruct the patient to avoid eating or drinking before the surgery begins.

On the day of your procedure, you’ll want to wear comfortable, loose fitting clothes. It’s important to be comfortable as you’ll be sedated during the surgery. The patient will also need a family member or friend to drive them to the clinic as well as back home. Following the procedure, patients will not be allowed to drive as they will be very incapacitated.

The implant is a permanent part of your mouth which cannot be removed. They act the same as having a regular tooth and look very natural. As with your normal teeth, these will need to be cleaned on a regular basis. However, this process is very easy to do. Clean the implant just as you would your normal teeth which means brushing twice daily. Read more… »
