| Description |
These
are the implants that were originally designed by Dr. P. I. Brånemark
and his fellow researchers in Sweden. They are cylindrical in shape
and
are inserted into bone in a specific manner. Several other companies have
developed clones and variations on the original Brånemark design
and even the Nobel Biocare company has changed the design from time
to time, especially after taking over the Sterr-Oss Implant Company. |  | | Surgical
Advantages: |
Endosseous
implants are basically cylinders (with or without threads) and as
such require
a cylindrical osteotome (a round hole) to place them making them the easiest
implants of all to place consistently. Since they approximate the
general
size of a normal tooth root. They can easily be placed in sites where roots
existed making them very versatile for replacing one or more teeth.
Installation
is very consistent across the group of implants in this category often
allowing the dentist to simplify the armamentarium. These implants
may be straight sided or tapered.
| | Surgical
Disadvantages |
The
surgery requires fairly strict observance of the Brånemark protocol
for implant placement and a sophisticated approach towards manipulating
bone and soft tissues. While this is not a disadvantage per se, it is an
indication that placement of endosseous root form implants requires a rather
high level of training and a total regard for the hard and soft tissues
in the area
| | Prosthetic
Advantages |
The
basic cylindrical shape is also very conducive to attaching a single tooth
restoration while still allowing for the placement of bridges and overdenture
restorations in multiple situations. The ability to precisely locate the
implant in the position occupied by a root is also a tremendous advantage
in prosthetic reconstruction.
| | Prosthetic
Disadvantages |
Placement
of implants in poor position relative to the tooth location will be difficult
to correct. Present technique can only specify to place the implants in
ideal position. Basically poor technique is poor technique, but these systems
have very little tolerance for poor technique.
| | Economics |
These
implants are easy and economical to manufacture. They can be made anywhere
around the world and titanium is the most Abundant metal we have. Manufacturers
add on quite a bit and then dentists add on even much more, but considering
the service, they are cost effective. Please note that there is tremendous
variation in dentist fee schedules for implant services...
| | Recommendations | There
is no question in my mind that the endosseous root form implant is the standard
for dentistry today. | |
