In Vitro Comparative Study Between Full-Arch Conventional Implant Impressions And Full-Arch Digital Implant Impressions With Snap-On Scan Bodies, Thomas H. Yoo 2022 University of Pennsylvania

In Vitro Comparative Study Between Full-Arch Conventional Implant Impressions And Full-Arch Digital Implant Impressions With Snap-On Scan Bodies, Thomas H. Yoo

Dental Theses

Statement of Problem: Digital impression techniques are widely used in everyday cases. There is sufficient evidence to support this technique in partially edentulous patients but the evidence supporting the use of intraoral scanners (IOS) in restorative digital workflows for edentulous patients is still limited.

Purpose: The aim of the present in vitro study was to measure and compare the accuracy of full- arch conventional implant impressions with open and closed-trays, full-arch digital implant impressions with intraoral scanners (IOS), and three-dimensional (3D) printed casts from the full-arch digital implant impressions.

Material and methods: Six implants were placed into a mandibular model ...

Journal of Dentistry Indonesia

The limitation of residual bone height (RBH) and vital structures such as sinuses in the maxillary often make the implant placement procedure becomes complicated. Clinicians may perform sinus elevation prior to implant placement to accommodate the length of the implant fixture. Sinus elevation is an invasive procedure and complication may occur during the surgery including the most frequent complication is perforation of Schneiderian membrane.

Objectives: To discuss a comprehensive management of implant placement and its complication step by step from surgical procedures to crown placement.
