Survival rate and stability of surface-treated and non-surface-treated orthodontic mini-implants: a randomized clinical trial [PDF]
Dental Press Journal of Orthodontics, 2023 Objectives: This clinical trial was conducted to evaluate the stability and failure rate of surface-treated orthodontic mini-implants and determine whether they differ from those of non-surface-treated orthodontic mini-implants.

On the Surface Porperties of Surface-Treated Polytetrafluoroethylene
Kobunshi Kagaku, 1961 ポリ四フッ化エチレンの未処理面およびナトリウム-ナフタリン-テトラヒドロフラン法とナトリウム-液安法による処理面の水に対する接触角を液滴法で測定した。未処理切削面の接触角は切削方向と平行で108°, 垂直方向で115° であった。ナトリウム-ナフタリン法による処理面は52° の比較的安定な接触角を処理条件を変えても示すのに反して, ナトリウム-液安法ではそれらの処理条件によって変化する接触角が得られる。これらの差は吸着坐席の分布状態と表面におけるあらさが関係しているようである。

Surface characteristics of thermally treated titanium surfaces [PDF]
Journal of Periodontal & Implant Science, 2012 The characteristics of oxidized titanium (Ti) surfaces varied according to treatment conditions such as duration time and temperature. Thermal oxidation can change Ti surface characteristics, which affect many cellular responses such as cell adhesion, proliferation, and differentiation.

Stm of Glow-Discharge Treated Surfaces [PDF]
Biomaterials, Artificial Cells and Immobilization Biotechnology, 1993 As a model surface, graphite slides were treated by pure nitrogen gas plasma for different periods (15 sec-5 min). These samples were kept in air or under argon atmosphere in sealed holders. STM images were obtained at constant current mode. Results showed that both the number and the size of clusters formed by plasma deposition increased with exposure
