Osseointegrated Implant with Cam Connection (CAMLOG Implant System) is an osseointegration based system and has been reported to be outstanding particularly in case of tooth reconstruction; however, there are no reports on clinical cases conducted in Japan in this respect.
At the Department of Oral and Maxillofacial Surgery of the hospital attached to Tokyo Women's Medical University, a total of 75 implants was placed during the period from June 2000 to December 2002 for 15 male and 15 female patients aged between 42 and 64. Among those cases 71 implants were set with superstructures for at least 6 months.
Four implant types, Screw-cylinder, Cylinder, Root-form and Screw-line, are currently available with the CAMLOG system. Regarding the break-down of implants placed, 58 Screw-cylinder implants (81.7%) were the most numerous among the four types. Forty-four implants (62.0%) were 13 mm in length and 59 implants (83.1%) were 4.3 mm or larger in diameter.
Concerning superstructures, 39 implants (54.9%) received a single crown. In total, 42 straight abutments (59.2%) and 29 angled abutments (40.8%) were used. Forty-six (64.8%) had a crown/implant ratio (CL/IL) of 0.8 or less, and 31 out of them (67.4%) were restored by a single crown. Increasing the CL/IL ratio leads us to use more connecting prosthesis.
The Periotest value was negative in all cases. Its mean value was -4.23 at the time of prosthetic delivery and -4.53 at the time of second measurement (5-9 months later).
These values show the good status of occlusal function from the initial stage of occlusal reconstruction. There has been no screw loosening or prosthetic failure in the CAMLOG Implant System so far. This result suggests that the system can be safely used either in tooth for tooth or connecting reconstructions.
