Custom made Tool for Parallel Placement of Implants
Parallel placement of dental implants is an accepted surgical and prosthodontic norm when multiple implants are used. Use of paralleling pins supplied with the implant kit is an arbitrary method. An instrument is designed that helps in maintaining the parallelism between implants intraorally. The instrument consists of a horizontal plate with millimeter graduation. A slot is created in the horizontal plate to house a vertical rod. The vertical rod can move mesiodistally as well as occlusogingivally. It must be ensured that the vertical rod is exactly parallel to the long axis of the drill in all the directions. The horizontal plate is then securely attached to the handpiece. After the first osteotomy is made, the vertical rod is placed in the site. The position of vertical rod will guide the second drill parallel to the osteotomy site. This instrument will guide us to correctly determine the inter implant distance, and also depth of the preparation. The instrument is autoclavable.
