One-Piece Versus Two-Piece Abutments for Single Crowns in the Esthetic Zone: A Clinical Trial.
Clin Oral Implants Res
October 2024
Article Synopsis
- The study aimed to compare the effectiveness of two-piece and one-piece abutments in terms of esthetics, patient satisfaction, and oral health quality for single crowns on implants.
- Thirty implants were randomly divided into two groups (15 each) and various measurements for esthetics, satisfaction, and quality of life were taken at different time points.
- Results showed no significant differences between the two types of abutments, with both improving patient satisfaction and esthetics over time, indicating they are equally effective.
Objective: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are effective procedures to treat and manage type 2 diabetes (T2D). However, the underlying metabolic adaptations that mediate improvements in glucose homeostasis remain largely elusive. The purpose of this study was to identify metabolic signatures associated with biochemical resolution of T2D after medical therapy (MT) or bariatric surgery.

Due to peer reinforcement, the internal confidence η_{i} of a normal voter increases in steps of size Δη. Once it surpasses a given threshold, it becomes a zealot.
View Article and Find Full Text PDFTwo-frequency excitation has recently emerged as an efficient method to generate strong chaotification of Duffing and Duffing-like dynamical systems with both single- and double-well potentials. For the systems with a double-well potential, large continuous regions with robust chaos (chaotic attractor insensitive to changes in the system parameters) have been predicted to exist when the method is applied. Motivated by these theoretical results, in this work, we investigate experimentally the chaotification under two-frequency excitation of a simple electronic circuit analogous to the double-well Duffing oscillator.

This review represents a systematic examination of these manifestations, as well as oral features associated with PYCD.
