Impression - parallel vs non-parallel implants

Key points

  • The use of angulated implants to improve patient rehabilitation leads to the intentional and desirable placement of non- parallel implants which affects impression procedures
  • It is important to evaluate the parallelism of implants to determine the impression technique that will be used
  • When the implants are relatively parallel to one another, either a closed tray or open tray impression technique can be used
  • The open tray technique is required when the implants are not parallel to one another
