Reflection of an ultrasonic wave on the bone-implant interface: effect of the roughness parameters [PDF]

, 2019
Quantitative ultrasound can be used to characterize the evolution of the bone-implant interface (BII), which is a complex system due to the implant surface roughness and to partial contact between bone and the implant. The aim of this study is to derive the main determinants of the ultrasonic response of the BII during osseointegration phenomena.

Effect of Medications in Osseointegration

Journal of Multidisciplinary Dental Research, 2023
Implants have been a modern solution for treating edentulism nowadays. But the effect of certain diseases as well as medications marks a question among the dental practitioners about the survivability of implants. This article aims to discuss the effect of certain medications and its effect in osseointegration.

High‐Performance 3D Printed Mechanically Interlocked Soft–Hard Interfaces of Hydrogels and Polylactide

Advanced Materials Technologies, EarlyView.
In this work, a methodology is presented for the design, fabrication and characterization of soft–hard interfaces consisting of extremely soft hydrogel biomaterials, and much harder rigid polymeric biomaterials. This approach enables the production of interfaces with performances close to predicted values, with applications in biomaterial fabrication ...

A multicenter randomized controlled clinical pilot study of buccally micro‐veneered lithium‐disilicate and zirconia crowns supported by titanium base abutments: 1‐year outcomes

Clinical Oral Implants Research, Volume 34, Issue 1, Page 56-65, January 2023., 2023
Abstract Objectives To investigate survival rates, technical and biologic outcomes of buccally micro‐veneered all‐ceramic single implant crowns. Material and Methods Sixty subjects randomly received immediately or early placed implants. Crowns out of lithium‐disilicate (n = 30) and zirconia‐ceramic (n = 30) were bonded to titanium‐base‐abutments ...

Manufacture of titanium alloy materials with bioactive sandblasted surfaces and evaluation of osseointegration properties

Frontiers in Bioengineering and Biotechnology, 2023
Titanium alloys are some of the most important orthopedic implant materials currently available. However, their lack of bioactivity and osteoinductivity limits their osseointegration properties, resulting in suboptimal osseointegration between titanium ...

Bioactive sphene-based ceramic coatings on cpTi substrates for dental implants: An in vitro study [PDF]

, 2018
Titanium implant surface modifications have been widely investigated to favor the process of osseointegration. The present work aimed to evaluate the effect of sphene (CaTiSiO5) biocoating, on titanium substrates, on the in vitro osteogenic ...

Compressive osseointegration for endoprosthetic reconstruction

Orthopedic Reviews, 2020
This review summarizes the biomechanical concepts, clinical outcomes and limitations of compressive osseointegration fixation for endoprosthetic reconstruction. Compressive osseointe - gration establishes stable fixation and integration through a novel mechanism; a Belleville washer system within the spindle applies 400-800 PSI force at the boneimplant

Total avulsion of an osseointegrated screw [PDF]

The Journal of Laryngology & Otology, 1991
AbstractThe close union achieved between pure grade titanium and healthy bone makes dislocation a rare event. We report the case of the total avulsion of an apparently well-integrated implant from a healthy mastoid bone.

A Multifunctional Nanodelivery System Modified by Fusion Peptides Acts as Teriparatide Carrier for Noise‐Induced Hearing Loss Therapy

Advanced Science, EarlyView.
The fusion peptide LR27‐modified thermosensitive nanodelivery system exhibits both hair cell targeting and inner ear penetrating properties. This system sustainably and effectively delivers PTH1‐34 to the inner ear of a hearing loss mouse model via the synergistic effects of multiple peptides, achieving satisfactory hearing protection through ...

Progress towards 3D-printing diamond for medical implants: A review [PDF]

arXiv, 2020
Additive manufacturing or 3D-printing is used to create bespoke items in many fields, such as defence, aerospace and medicine. Despite the progress made in 3D-printed orthopaedic implants, significant challenges remain in terms of creating a material capable of osseointegration while inhibiting bacterial colonisation of the implant.
