“…Laser and micro pulse welding is mainly used in dentistry for repairing damaged metallic parts of partial dentures or orthodontic appliances [25]. If welding is used for repairing or completing damaged areas of prosthetic pieces, structural modifications are expected, especially in TAA, regardless of the welding type.…”

Laser welding permits joining various types of pieces, made of similar or different alloys, as titanium-based alloys, CoCr alloys, and even AuPd alloys. Laser welding is best suited to weld titanium alloys because they have higher rates of laser beam absorption and lower thermal conductivity compared to other dental casting alloys. Compared to micro pulse welding, laser welding is superior, obtaining the welding cord being faster and easier. The success of the welding procedure depends on the operator's dexterity and the choice of the welding parameters. Selecting the best combination of pulse energy, pulse duration, and peak power for each welding step is decisive.

“…As a rule, laser welding is mechanically satisfactory. (Szuhanek, 2010) In order to avoid problems, initially, both parts of the joined piece should be subjected to low level energy impacts, followed by greater energy for filling. (Baba& Watanabe, 2005) The success of the welding procedure also depends on the operator's dexterity and the choice of the welding parameters.…”

The aim of this study is to assess the characteristics of laser welding, by different methods such as: scanning electronic microscope observation and metallography. The quality of welding can also be tested by non-invasive methods, which make possible its macro-and microscopic assessment. The alloys assessed are a titanium-based alloy, a standard Au-Pd alloy for the metallo-ceramic technique and a Cr-Co-Mo alloy. The conclusion of the testing is that laser welding is generally mechanically satisfactory.

“…Lower incisor extractions are indicated only in crowding cases (<5 mm) but translational movements of the teeth are hard to achieve, even with attachments. We recommend oral buttons (added on the aligners) to improve the results and top prevent tipping [Szuhanek C., 2010].…”

“…The need for resin attachments/other metallic accessories [Szuhanek, 2010] is dictated by some of the complex orthodontic movements or situations, such as incisor and molar torque, extrusions, cylindrical teeth, severely rotated teeth, extraction cases, translational movements. Attachments can vary a lot, depending on the required dental movements.…”

Vacuumformed Thermoplastic Aligners in Orthodontics

Thermoplastic aligners are frequently used in orthodontics when it comes to the correction of mild malocclusions These appliances are very popular because they provide an esthetic and comfortable alternative to conventional treatment due to their translucency and reduced thickness. The thermoplastic aligners are well fitted and offer good treatment results if they are worn properly. Aligners have less social impact than braces. The foils that are used for the vacuumforming process are made out from clear thermoplastic material, such as polyethylene or PC. The polyethylene has enough stiffness to provide the desired tooth movements and helps patients to maintain a good oral hygiene. Aligners must be changed every two or three weeks until the final result is reached. Material thickness can also be increased during the treatment period in order to assure stiffness and reduce the total treatment time.
