Nano‐Engineered Titanium Implants Loaded With Gingival Fibroblasts‐Derived Microvesicles Enhance Early Osseointegration And Soft Tissue Attachment In Vivo

open access: yesAdvanced Healthcare Materials, EarlyView.
Our study showed that human primary gingival fibroblast–derived microvesicles on nano‐engineered titanium implants promote early osseointegration and soft‐tissue attachment in vivo. ABSTRACT Titanium dental implants require both reliable osseointegration and peri‐implant soft tissue seal formation to ensure long‐term success. While osseointegration has

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

open access: yesAdvanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

Inner canthal distance and golden proportion as predictors of maxillary central incisor width in south Indian population

open access: yesIndian Journal of Dental Research, 2010
Objectives: Even though the constant relation of golden proportion and inner canthal distance (ICD) with the width of the maxillary central incisor (CIW) has been found in European population, it may not be applied to Indian population as we differ from ...

Why the $41 Trillion Wealth Transfer Estimate Is Still Valid: A Review of Challenges and Questions [PDF]

open access: yes, 2003
Despite the economic downturn and the fall of the equity markets, the nationally noted projection that a wealth transfer of at least $41 trillion will take place in the United States by the year 2052 remains valid. Following a thorough review of our 1999

Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

open access: yesAdvanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

Evaluation of Prevalence of Golden Percentage, Recurring Esthetic Dental (RED) and Tarulatha-Ruchi (TR) Proportion in Dental Students

open access: yesJournal of Pharmacy and Bioallied Sciences
Background: One of the important concepts in aesthetic dentistry is “the principle of gradation,” where each tooth appears proportionally narrower than its mesial neighbor as the eye moves laterally from the midline.

A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...
