Surgical Insertion of an Implant
Prosthetic devices, such as bridges and dentures may not work for
everyone, and may be due to reasons of an improper fit, an
annoyance, or some people simply cannot wear them. Implants were
designed to insert or implant an anchor that would connect
prosthetic teeth to underlying bone as securely as natural teeth.
There are various types of implants, but most are called endosseous
because they are placed inside the bone. Endosseous implants,
needless to say, require very careful insertion. The procedure is
as follows: (1) An incision is made into the gum where the implants
are to be inserted and the gum is pulled back to reflect the bony
ridge; (2) Holes are drilled into the bone starting with a small
pilot hole and is gradually enlarged; (3) The implants are
cylindrical and are usually partially threaded. Each implant is
slowly screwed into the bone until its top is level with the bone
surface. A temporary protective cap is placed over it, and the gum
tissue is sutured where the implants will remain secure and
undisturbed from 4 to 12 months, and (4) This begins a second phase
of surgery. A small incision is made over the implant site to
expose it, and the temporary covers are removed, and in their
place, titanium abutment cylinders are used. The abutments
protrude slightly above the gum and will form the base for the
prosthetic denture or bridge; (5) They are covered with plastic
caps, and are sutured if necessary; (6) A new impression of the jaw
is now taken. The protective caps are removed and devices called
impression copings are used, and these become guides for the
precise placement of the prosthetics as it is related to the
abutment; (7) Screws or posts will fasten artificial teeth to the
abutments. A denture fastened to an implant does not require a
base, or an artificial gum to secure it in the mouth.
Implanted bridges and dentures are stable and comfortable. They feel
and function like normal teeth. There is virtually nothing that
cannot be chewed with these types of restorative devices. Implants,
however, cost several times more than other restorative dental devices.
