Achieving fast and strong adhesion to jawbone is essential for dental implants. Thin deposited films may improve osseointegration, but they are prone to cohesive and adhesive fracture due to high stresses while screwing the implant into the bone, leading to bared, less osteoconductive substrate surfaces and nano-and micro-particles in the bone. Aim of this work is the investigation of the cohesion and adhesion failure stresses of osteoconductive tantalum, titanium, silicon, zirconium and aluminium oxide and diamond-like carbon films. The tribological behaviour under dry and lubricated conditions (Ringer solution) reveals best results for diamond-like carbon, while cohesion and adhesion of zirconium oxide films is highest.Keywords: biotribology, thin films, lubricationOsiągnięcie szybkiego i trwałego przylegania powierzchni biomateriału do kości szczęki ma zasadnicze znaczenie dla implantów dentystycznych. Cienkie osadzone filmy mogą poprawić osteointegrację ale są podatne na kohezyjne i adhezyjne pękanie podczas wkręcania implantu do kości, prowadząc do odsłoniecia mniej osteokonduktywnych powierzchni podłoża oraz powodując tworzenie się nano-i mikro cząstek. Celem niniejszej pracy są badania naprężeń wywołujących defekty w osteointegracyjnych filmach na bazie tantalu, tytanu, cyrkonu oraz tlenku aluminium i diamentopodobnych. Tribologiczne najlepsze właściwości w warunkach suchych i smarowania (roztwór Ringera) wykazały powłoki diamentopodobne, natomiast spójność i przyczepność filmy z tlenku cyrkonu.

“…Preliminary ion etching (Ar + , E = 4 keV, P = 6 × 10 −2 Pa, 30 min) of scaffold surface was carried out. Our earlier studies have shown that the DLC coating reduces the risk of dystrophy of the mother bone contacting with scaffold and accelerates the formation of a mechanical interlocking in the bone-implant interface [12].…”

Properties of biocomposites based on titanium scaffolds with a different porosity

Open-porous titanium scaffolds have been widely investigated for orthopaedic and dental applications because of their ability to form composites via bone ingrowth into pores and promote implant fixation with mother bone. In this work, porous titanium scaffolds coated with a diamond-like carbon were produced, and their ability to form biocomposites was evaluated through in vivo experiments. Three types of the open-porous scaffolds made of spongy titanium granules (porosity 0.3, 0.4 and 0.5, Young's modulus 4.4, 3.5 and 0.6 GPa) were implanted into a bone defect of sheep. Time dependences of the Young's modulus of titanium scaffold-bone tissue biocomposites were determined through the measurement of Young's modulus of the extracted scaffolds after 4, 8, 24 and 52 weeks of surgery. The Young's modulus of biocomposite is dependent not only on the time of composite formation but also on the porosity of scaffold.

“…In order to avoid detrimental tissue reactions and implant rejection, MBI must be as biocompatible as possible 5 . Any mismatch between metal implant and surrounding biological tissues causes stress strain state at MBI, adversely affecting tissue remodelling and bone healing 6 . Ideally, all parts and implants intended for use in human or veterinary medicine must be highly resistant to corrosion, fatigue and wear.…”

“…Wear at the contact points is inevitable in prosthesis and implants, because of that, strategies to reduce its effects are being investigated 7 by using inert films as like nano and microcrystalline diamond films. In this regard, some studies show promising results with carbon-based films, such as diamond-like carbon 6,8 and diamond films 9 . The use of very hard film, besides hiding the imperfections of the surfaces, contributes to the decrease of the wear, due improvements in the surface-carrying capacity.…”

Fibroblast and pre-osteoblast cell adhesive behavior on titanium alloy coated with diamond film

et al. 2017

It is well known that titanium alloys have mechanical strengths comparable to steels, as well as high corrosion resistance. Also, they have the advantage of promoting osseointegration, when used in medical and dental implants. This work aims to describe the adhesion properties of fibroblast and osteoblast cells on the surface of titanium aluminum vanadium alloy (Ti6Al4V). Three different conditions of the surface were investigated: smooth, rough and covered with diamond film. Conventional material characterizations were performed to the film which consisted in: Morphological visualization by scanning electron microscopy, confocal profilometry, X-ray diffraction pattern, Raman backscattering spectroscopy and atomic force microscopy. Biocompatibility tests of Ti6Al4V were performed using primary human fibroblasts and mouse pre-osteoblasts cell line MC3T3-E1. Overall, diamond films deposited on Ti6Al4V showed interesting results of uniformity and protection against cracks on to the surface, reasonable biocompatibility features if compared to uncovered ones, indicating that this film is an alternative for using in health care applications.
