Replacement Of Missing Teeth With Implant Dentistry
In implant dentistry, devices are used to replace missing teeth. They are made of titanium, an inert metal that bonds with the bone, forming a very tight union called osseointegration. The modern system of dental implants, the endosseous system, is extremely successful and has a 90% to 95% success rate.
The dental implant itself replaces the root of the tooth. It is usually in the shape of a screw or a cylinder. The implant connects to a component (the abutment) that joins the implant to the replacement tooth (the crown).
Dental implants are ideal replacements for teeth. When healthy teeth have to be prepared for crowns or bridges, healthy tooth structure needs to be removed. But if only one tooth is missing, the dental implant can simply replace it without having to sacrifice the adjacent teeth.
Dental implants can also be used to replace many missing teeth. Multiple teeth can be replaced with
implant dentistry and can avoid the need for a removable denture. Removable dentures can be hard to get used to. They may have clasps that can be unsightly and put additional stress on the existing teeth. Full dentures may be difficult to wear and may interfere with eating and speaking. People who wear dentures for a long time may have additional loss of the bone that supports the denture. This bone loss can be accelerated by osteoporosis, and eventually dentures may be very difficult to wear if not impossible. Poor-fitting dentures can interfere with proper nutrition and quality of life.
Generally, one implant is needed to replace each missing tooth. In some situations, several implants need to be joined together into a bridge. This adds greater strength to the implant restoration. If there is not enough bone available to replace a whole set of teeth, implants may be used as anchors for dentures. When dentures are supported by implants they can be much more stable and the implants help prevent the deterioration of the bone that supports the denture.
The endosseous system of implant dentistry has been used for over 30 years. They can look and feel like natural teeth, adding comfort and improving the smile of people of all ages.

Immediate Dental Implants: What Are They?
Implant dentistry is a safe, predictable method for replacing missing teeth. "Immediate dental implants" or the placement of tooth implants at the time of extraction is a great method of implant placement. This method can be considered when a single upper front tooth is traumatized, when one or two teeth have advanced decay, or when the remaining roots are too short to support a crown. The purpose of this method of tooth replacement is to maintain as much bone volume as possible. This means preserving bone height and width. The benefits to the patient after restoration of dental implants are a beautiful, natural-looking tooth without cutting down healthy adjacent teeth and being able to eat in comfort without the fear of having the tooth loosen or fall out.
An implant dentist can easily determine if a person is a candidate for the immediate dental implants method of replacing missing teeth. They will examine the teeth adjacent to the involved tooth for periodontal disease and take a traditional dental X-ray. Impressions of the teeth will aid in determining one's prognosis. Additional X-rays may be necessary to determine the exact bone width and height, as well as the root position.
Implant placement is performed with local anesthesia. The remaining root is removed and the gum tissue is gently displaced from the surrounding tissue. The dental implant site is prepared with small drills. Special equipment is used to gently place the tooth implant into the prepared site, after which the gums are replaced over the implant with sutures. A temporary tooth replacement is placed in the space where the tooth was removed. Post-operative discomfort is minimal. The sutures are removed in a week, and oral hygiene is resumed.
In the upper jaw, bone grows and adheres to the tooth implant within five to six months, while the immediate dental implants in the lower jaw require three to four months for proper bone formation. After healing, there is a series of visits when an implant dentist will make a tooth that will be attached to the implant. Within a few weeks after receiving the implant-supported crown, patients consider the restoration as their own tooth, rather than an implant.
Implants require good oral hygiene, dental maintenance, and periodic evaluation by a dentist.
