The aim of this study was to investigate the surface propertity and biocompatibility of Ti and Ti6Al4V after the treatments of sandblasting by Al 2 O 3 and etching by hydrochloric acid-sulfuric acid mixture. Surface morphology of samples was observed using scanning electron microscopy and the roughness and three-dimensional structures were detected by 3D laser scanning confocal microscope. Simulated body fluid (SBF) tests were conducted to compare the biocompatibility of the samples. The size of the contact angle was measured by a microscope using a measuring instrument. After sandblasting and acid etching, the surfaces of Ti and Ti6Al4V presented micron-size porous morphology and were hydrophilic. Even though microstructures of the alloys exhibited somewhat similar, the deposition of calcium (Ca) and phosphate (P) on the surface of Ti6Al4V alloy was greater and faster than that of Ti, which is significant for dental implants. Sprague-Dawley rats were seeded on the surfaces of Ti and Ti6Al4V and their adhesion observed using Calcein-AM staining. Surface modification of Sandblasting and acid etching promoted bioactivity of Ti and Ti6Al4V surfaces, although sandblasted and acid-etched Ti6Al4V showed better biocompatibility than Ti.

“…Two studies also investigated a tipping angle ranging from 1.0 to 2.65°. 53,54 The mean extrusion of the mini-implants ranged from 0.1 to 0.8 mm, with only one author reporting intrusion of up to 0.5 mm.…”

“…Liou et al 30 discussed whether a healing period of 2 weeks was too short to obtain sufficient osseointegration. Perhaps a treatment of the mini-implants' surface might affect the process of osseointegration and therefore the displacement behaviour, as suggested by Calderon et al 53 …”

Systematic review of mini-implant displacement under orthodontic loading

2013

A growing number of studies have reported that mini-implants do not remain in exactly the same position during treatment, although they remain stable. The aim of this review was to collect data regarding primary displacement immediately straight after loading and secondary displacement over time. A systematic review was performed to investigate primary and secondary displacement. The amount and type of displacement were recorded. A total of 27 studies were included. Sixteen in vitro studies or studies using finite element analysis addressed primary displacement, and nine clinical studies and two animal studies addressed secondary displacement. Significant primary displacement was detected (6.4–24.4 µm) for relevant orthodontic forces (0.5–2.5 N). The mean secondary displacement ranged from 0 to 2.7 mm for entire mini-implants. The maximum values for each clinical study ranged from 1.0 to 4.1 mm for the head, 1.0 to 1.5 for the body and 1.0 to 1.92 mm for the tail part. The most frequent type of movement was controlled tipping or bodily movement. Primary displacement did not reach a clinically significant level. However, clinicians can expect relevant secondary displacement in the direction of force. Consequently, decentralized insertion within the inter-radicular space, away from force direction, might be favourable. More evidence is needed to provide quantitative recommendations.

“…Tem sido confirmado pela literatura que os MIs sofrem deslocamento após aplicação de carga. 17 O deslocamento de MIs tem sido avaliado usando diferentes métodos como radiografias cefalométricas,13,33,[166][167][168][169] radiografias oclusais,170 tomografias computadorizadas48,171 e TCFC 111. Embora tenha sido demonstrado que a TCFC seja um método de maior precisão na avaliação do posicionamento de MIs quando comparado com métodos radiográficos, 172,173 a alta dose de radiação desse exame e o custo são desvantagens que impedem ainda seu uso rotineiro 174.…”
