Abstract

In the full arch digital implant impression, the use of intraoral scanners is still considered a challenge. However, today, the use of intraoral scanners in full arch implant scanning is possible, provided the operator is familiar with the key factors in determining the quality of the impression. These factors are:

• The intrinsic accuracy of the scanner.
• The scanning strategy and operator experience.
• The number, position, inclination and depth of the implants.
• The environmental conditions.
• The type of scanbody chosen.
• The congruence between scanbody mesh and implant library.

In this lecture, the speaker will report on all these factors and their influence in determining the final quality of the impression. He will also addresses novel and important topics like the use of solid indexes, auxiliary devices, extraoral and intraoral photogrammetry, as modern tools for helping clinicians to obtain high quality full arch impressions.

Learning objectives

• Discuss the topic of full arch implant impressions.
• Explain how to eliminate obstacles using the conventional scanning tools and techniques.
• Demonstrate how solid indexes, auxiliary devices, extraoral and intraoral photogrammetry can represent a valid alternative for digital full arch implant impressions.
