Comparison of Intraoral Scanning Modes in Three Distinct Full- Arch Digital Implant Impression Scenarios: An In Vitro Study.

Purpose: To analyze the effect of scanning modes on the accuracy of the Trios intraoral scanner (IOS) for full-arch digital implant impressions.

Materials And Methods: The trueness and precision of the intraoral scanning mode (IOSM) and the intraoral edentulous scanning mode (IOEM) of the Trios IOS were evaluated in three edentulous models, each featuring four, six, and eight implant analogs. Reference scanning data were obtained by scanning each model with a desktop scanner.

Trueness of Intraoral Scanners in Different Scan Patterns for Full-Arch Digital Implant Impressions.

The optimal scan pattern for full-arch digital implant impressions remains to be determined. This study aimed to analyze the effects of different scan patterns on the trueness of intraoral scanners for full-arch digital implant impressions. A maxillary plaster model with 4 implant analogs was employed as the master model.

COVID-19 as a factor associated with early dental implant failures: A retrospective analysis.

Objectives: To analyze the effect of COVID-19 on early implant failures and identify potential risk factors for early implant failure, concerning patient- and implant-related factors.

Materials And Methods: This retrospective study is based on 1228 patients who received 4841 implants between March 11, 2020, and April 01, 2022, at Erciyes University Faculty of Dentistry. COVID-19, age and gender of patients, smoking, diabetes, irradiation, chemotherapy, osteoporosis, the implant system, location, and characteristics of implants were recorded.

Effect of Implant Diameter and Bruxism on Biomechanical Performance in Maxillary All-on-4 Treatment: A 3D Finite Element Analysis.

Purpose: To examine the stress distribution in the maxillary All-on-4 treatment concept supported by implants of different diameters under two different loading forces using finite element analysis.

Materials And Methods: Two distinct All-on-4 designs were prepared in a fully edentulous maxilla, supported by 3.3- and 4.

Effect of Anterior Implant Position on Biomechanical Performance in the Maxillary All-on-Four Treatment: A 3-D Finite Element Analysis.

In the all-on-four concept, the positions of both posterior and anterior implants can affect stress distribution. The aim of this study was to examine the effect of the position of anterior implants on stress distribution in the implant, the bone around the implant, and prosthetic components in the resorbed maxilla using the all-on-four concept. All-on-four designs were prepared with 3 different anterior implant positions in a fully edentulous maxilla.
