“…As osseointegration is also guaranteed by good biocompatibility of the implant, different coatings have been developed to improve the biocompatibility and bioactivity of the implants. The use of coatings consisting of SiO 2 -based materials [60][61][62][63][64][65][66], and other alkali metal oxides-based glasses and ceramics (e.g., TiO 2 [67][68][69][70][71], ZrO 2 [11,72], and ZrTiO 4 [73]), entirely inorganic or organic-inorganic hybrids (OIHs), has been widely studied due to the known high biocompatibility of such materials [74][75][76][77]. Moreover, such studies show that the use of OIHs coatings is advantageous in term of coating morphology.…”

The limited lifetime of implants entails having patients undergo replacement surgeries, several times throughout life in young patients, with significant risks for them and extensive cost for healthcare service. The overcoming of such inconvenience is still today a hard challenge for the scholars of the biomedical and biomaterial fields. The improvement of the currently employed implants through surface modification by coatings application is the main strategy proposed to avoid implants failure, and the sol-gel coating is an ideal technology to achieve this goal. Therefore, the present review aims to provide an overview of the most important problems leading to implant failure, the sol-gel coating technology, and its use as a strategy to overcome such issues.

“…Nevertheless, due to its brittleness, low tensile strength, and low fracture toughness, hydroxyapatite is inappropriate for usage as loaded-bearing material in orthopedic surgery or internal fixation devices [3][4][5]. With properties including lightweight, good formability and high corrosion resistance that suit the requirements for applications, stainless steel and titanium metal are currently utilized as the materials for internal fixation devices [6][7][8].…”

Hydroxyapatite (HA, Ca10(PO4)6(OH)2) is a biomaterial exploited in bone graft and implant coating applications. The present study aimed at developing the technique employed in coating hydroxyapatite onto internal fixation titanium plates. The coating consisted of hydroxyapatite layer and titanium dioxide layer, functioning as a buffer layer between hydroxyapatite and titanium plate substrate. The titanium substrates were i) untreated; ii) polished and immersed in 70% nitric acid; and iii) immersed in nitric acid. Coating of titanium dioxide and hydroxyapatite layers were achieved via hydrothermal technique. Porous hydroxyapatite layers with the average pore size close to 120 Âµm, and porosity ranging from 40 to 45% were observed. Fair adhesion among titanium substrate, titanium dioxide and hydroxyapatite layers were found in the samples prepared by polishing and acid immersion and the ones prepared by acid immersion. A peeling method (ASTM D3359 â€“ 09E2), used in evaluation of adhesion on a 0B to 5B scale, was employed in determination of adhesion strength of the coating. The peeling results revealed that complete detachment of the buffer and hydroxyapatite layers occurred in untreated substrates. For the polished and acid immersed samples, the 2B category adhesion, which corresponds to film removal between 15 to 35%, was observed. The observation was being agreed with the image analysis which indicated that 67.7%-69% of coated area remained. Potential biocompatibility was tested by simulated body fluid (SBF) immersion. After 28 days, pH values remained unchanged. Slight weight increase and hydroxyapatite formation after immersion was observed, indicating potential bioactivity of the samples.
