# Customized Closed‐Tray Impression Post for Unknown Implant System: Case Report

## TL;DR

This case report presents a practical method for creating a customized implant impression post when the implant system is unknown, helping to accurately transfer implant positions for prostheses.

## Contribution

A novel technique for fabricating customized closed-tray implant components when the implant system is unidentified.

## Key findings

- A customized closed-tray impression post was successfully fabricated for an unknown implant system.
- The method facilitated accurate implant position transfer and prosthesis fabrication.
- The technique offers a practical solution for clinicians dealing with unknown implant systems.

## Abstract

Managing implants with unknown systems presents a significant clinical challenge when obtaining an accurate master impression. This case report describes a simple technique for fabricating a customized closed‐tray implant impression post and laboratory analog when the implant system cannot be identified. The use of these customized components enabled accurate transfer of the implant position and facilitated the fabrication of a definitive prosthesis. This case report highlights a practical solution for clinicians facing similar cases involving unknown implant systems.
