The abutment seating jig: a prosthodontic implant adjunct

Area of Science:

• Dental Implantology
• Prosthodontics
• Biomaterials Engineering

Background:

• Accurate placement of implant abutment components is critical for successful dental restorations.
• Current methods for seating screw-retained abutment heads can be time-consuming and prone to inaccuracies.
• The interface between the abutment head and implant body requires precise alignment for long-term stability.

Purpose of the Study:

• To introduce and describe custom-cast abutment head location devices for improving the seating accuracy of screw-retained implant abutments.
• To present a method for simplifying the process of cementing abutment head-implant body complexes.
• To detail the design and application of these devices in various implant-supported prostheses.

Main Methods:

• Development of patient-specific, custom-cast abutment seating jigs.
• Utilizing internal or external hex designs for controlled timing and seating.
• Application of the devices for both single-tooth and full-arch implant restorations.

Main Results:

• Demonstrated rapid and accurate seating of screw-retained implant abutment heads using the custom devices.
• Facilitated straightforward and reliable cementation of the abutment head-implant body complex.
• The devices proved effective for diverse prosthetic applications, including single implants and full-mouth reconstructions.

Conclusions:

• Individual, custom-cast abutment head location devices offer a significant improvement in the efficiency and accuracy of seating screw-retained implant abutments.
• These jigs are particularly advantageous for procedures involving permanent cementation of the abutment head-implant body complex.
• The described devices provide a valuable tool for clinicians performing implant dentistry, enhancing prosthetic outcomes.
