Biomimetic trace metals improve bone regenerative properties of calcium phosphate bioceramics
(
John Wiley and Sons Inc
, 2021 , Article)
The bone regenerative capacity of synthetic calcium phosphates (CaPs) can be enhanced through the enrichment with selected metal trace ions. However, defining the optimal elemental composition required for bone formation ...
The effect of aging on the bone healing properties of blood plasma
(
Elsevier Ltd
, 2021 , Article)
Objectives: Age-related changes in blood composition have been found to affect overall health. Thus, this study aimed to understand the effect of these changes on bone healing by assessing how plasma derived from young and ...

(
Mosby Inc.
, 2021 , Article)
Statement of problem: Durable titanium-porcelain bonding is challenging because of the formation of a thick oxide layer on the surface during porcelain firing. Purpose: The purpose of this in vitro study was to evaluate ...
Analytical model of I-bar clasps for removable partial dentures
(
Elsevier Inc.
, 2021 , Article)
Objective: Clasps of removable partial dentures (RPDs) often suffer from fatigue stress that leads to plastic deformation, loss of retention, and RPD failure. Recently, computer-based technologies were proposed to optimize ...

A truly bioinspired approach to design optimization should follow the energetically favorable natural paradigm of ?minimum inventory with maximum diversity?. This study was inspired by constructive regression of trabecular ...
Ranitidine Impairs Bone Healing and Implant Osseointegration in Rats' Tibiae
(
W.B. Saunders
, 2020 , Article)
Purpose: Ranitidine has been found to have an impact on bone metabolism by suppressing osteoclastogenesis. We hypothesized that the use of ranitidine would impair bone healing and implant osseointegration. This study ...
