“…Other drawbacks include the fact that precursors can be toxic, explosive, expensive, corrosive, the by-products can be hazardous, and films need to be deposited at elevated temperatures, which restricts the types of materials that can be coated [59]. CVD has been used in endodontics to coat NiTi files [60,61] and in the coating of burs used in dentistry [62,63]. The use of this technology for coating metallic substrates in orthodontics has not been reported.…”

Metallic biomaterials have been extensively used in orthodontics throughout history. Gold, stainless steel, cobalt-chromium alloys, titanium and its alloys, among other metallic biomaterials, have been part of the orthodontic armamentarium since the twentieth century. Metals and alloys possess outstanding properties and offer numerous possibilities for the fabrication of orthodontic devices such as brackets, wires, bands, ligatures, among others. However, these materials have drawbacks that can present problems for the orthodontist. Poor friction control, allergic reactions, and metal ionic release are some of the most common disadvantages found when using metallic alloys for manufacturing orthodontic appliances. In order to overcome such weaknesses, research has been conducted aiming at different approaches, such as coatings and surface treatments, which have been developed to render these materials more suitable for orthodontic applications. The purpose of this paper is to provide an overview of the coating and surface treatment methods performed on metallic biomaterials used in orthodontics.

“…However, diamond drills were the first to be featured in the dental market (2). The technology which can be applied to improve conventional diamond drills is somewhat limited due to the heterogeneous shape of diamond granules, and their short-term durability (3,4). Added to that, they remove a good part of the sound portion of the tooth structure (5).…”

Preparation time and sealing effect of cavities prepared by an ultrasonic device and a high-speed diamond rotary cutting system

et al. 2007

The purpose of this study was to compare a high-speed handpiece to an ultrasonic device regarding the time taken for cavity preparation in bovine incisor teeth (n = 12), and to evaluate microleakage after the restorations. Two cylindrical cavities each were prepared on the labial surfaces of 12 teeth. One of them was made with a diamond tip in group 1 (G 1 = 12) coupled with a high-speed handpiece, and the other with a chemical vapor deposition (CVD) tip in group 2 (G 2 = 12) coupled with an ultra-sound device (n = 24). The time taken for each preparation was measured with a stopwatch. The cavities were treated with adhesive (Scotchbond Multipurpose, 3M), restored with composite (Filtek Z250, 3M), finished and polished, and then the prepared teeth were immersed in a 50% silver nitrate solution. The samples were cut in the mesio-distal direction and evaluated for microleakage. Data were analyzed using the Wilcoxon test (P < 0.01). The results revealed that the time taken to prepare cavities was 7.9 times shorter in G 1 . There was no microleakage in 100% of the samples indicated by the absence of dye penetration in G 1 , and 46% in G 2 . It was concluded that the performance of the highspeed handpiece was better than that of the oscillatory system, in terms of both the time taken for preparation and the microleakage. (J.
