Implants have become a very important part of dentistry today.
An implant is a replacement for a tooth root. They are hollow titanium screws that are threaded on the inside and the outside. They can be used to replace one or more missing teeth.
To place an implant a tapped/threaded hole is drilled into the bone where the tooth used to be. We try to put it as parallel with the roots of the teeth adjacent to it and make the top flush with the edge of the bone and gum. Then a flat cover screw is put on top of the implant. After 3 to 5 months the bone will have attached itself to the outer walls of the implant and it is ready to take weight. The cover screw is removed and a post is screwed into the inside of the implant. This is called the abutment. An impression or mould is then taken so the technician can make a tooth that can be cemented or screwed onto this.
Placement of a single implant usually takes less than an hour
The cover screw is removed after 3-5 months and the abutment is screwed on. An impression is taken and sent to the lab where a technician fabricates a crown that is then screwed or cemented on. Placing an implant is a minor surgical procedure that usually takes about an hour. A person’s general health may influence the decision as to whether an implant can be placed. A necessary condition for implant placement is the presence of enough bone in depth and width. (See bone augmentation.)
