Enhancing the soft‐tissue integration of dental implant abutments—in vitro study to reveal an optimized microgroove surface design to maximize spreading and alignment of human gingival fibroblasts [PDF]

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2021
AbstractWithin this work, we demonstrate the influences of different microgrooved surface topographies on the alignment and spreading of human gingival fibroblast (HGF) cells and present the optimal parameters for an improved soft‐tissue integration design for dental implant abutments for the first time.

Digital Workflow for Implant Placement and Immediate Chairside Provisionalization of a Novel Implant System without Abutment—A Case Report

Medicina, 2022
Dental implants have been placed millions of times worldwide, and the surgical procedure and implant design have steadily improved. The basic prosthetic connection, which makes use of an abutment, has changed little over the past decades.

A Three-dimensional Finite Element Analysis of Effect of Abutment Materials on Stress Distribution around Peri-implant Bone in Immediate and Delayed Loading Conditions [PDF]

Journal of Clinical and Diagnostic Research, 2022
Introduction: Osseointegration is important for successful dental implant treatments. Abutment materials affect the load transfer to the implant and surrounding bone thus determining the long term implant survival. Aim: To perform stress analysis around

Computational Investigation of Dental Implant Restoration Using Platform-Switched and -Matched Configurations

Computation, 2023
Dental trauma is a serious and highly prevalent health issue across the globe. Most of the frequent dental injuries result in the loss of teeth and affects the overall quality of life. The loss of a tooth is usually compensated by a dental implant.
