Abstract
Implant placed in inadequate location causes many complications including esthetics, concentration of force on implants and prosthetic treatment. We asked 5 prosthodontics and 5 oral surgeons to form the channel for apatite 2-piece implant in plaster model of Kennedy class I case and examined the implant position.
As a result:
1.When the channel was formed without any instruction, there was no problem caused in buccolingual but there was in mesiodistal direction. The channel in 6 was formed slightly toward the distal and that in 7 was formed slightly toward the mesial,so that the positions might cause prosthetic problems..
2. The direction of the channel formed with or without instruction showed many variables in mesiodistal and buccolingual direction. There was the possibility that the variables in direction caused severe prosthetic treatment problem.
3. No significant difference was observed from the point of view of clinical experience of prosthetics and oral surgery. These data indicate that study must be made to find the technique of the channel formation to determine the exact direction and position of the channel when implant was inserted.
