ABSTRACT
Aim and Objective: A device was designed to be used together with a dental surveyor to determine the proper abutment angle combination in cases with multiple non-parallel implants
Background: Anatomical and technical difficulties may lead to unfavorable implant positioning and/or alignment. Angled abutments can be used to properly align non-parallel implants. Determining the required abutment angulation can be challenging especially with multiple implants.
Technique: An implant level impression is made and poured. Long impression posts are screwed onto the implant analogs to determine implant alignment. The cast is placed over the device platform that is placed over a dental surveyor. The angulation between implants is determined by aligning the long impression posts to the analyzing rod of the surveyor and the implant angulation is measured using the device.
Conclusion: This simple device determines the angle between multiple implants to achieve a common path of insertion for splinted multiunit restorations.
