Abstract

Background: Fixed retainer are a practical retention method because they require minimal cooperation from the patient. Fixed reteiner are made from various types of wire, one of which is nickel titanium. However, when using a fixed retention device, several problems arise, such as fracture of the wire, loss of bond between the surface of the wire and composite, failure of attachment of the composite to the teeth, and unexpected tooth movement. Objective: To determine the shape memory and superelastic properties of nickel titanium wire with dimensions of  0.010 x 0.030 inches used as a retention device after a three point bending test.  Method: This research is a laboratory experimental study using 5 samples of nickel-titanium wire measuring 0.010 x 0.030 inches. The wire length is 30 mm. The collected data was then tested using a tested. Results: Nickel titanium wire measuring 0.010 x 0.030 inches with a deflection of 1.5 mm shows a graph with a smaller hysteresis than a deflection of 2 mm with a wider hysteresis. Nickel-titanium wire measuring 0.010 x 0.030 inches with a deflection of 1.5 mm and 2 mm shows that the wire experiences permanent deformation before returning to its initial shape, which could be due to the amount of deflection applied exceeding the tensile yield strength range limit of the wire. Conclusion: The amount of deflection given to the nickeltitanium wire samples is 1,5  mm and 2 mm influences the amount of force released. The deflection of a given wire determines how much force can be generated when the wire is applied.

Abstract

In the field of orthodontics, study models play an important role as diagnostic aids, photogrammetry techniques are used to obtain three-dimensional digital study models. This study model provides an accurate representation of the patient's teeth and occlusion, as well as assists in identifying dental and bone anomalies. In the creation of study models, traditional techniques using cement or gypsum are time-consuming and prone to inaccuracies. Three-dimensional scanning is the process of collecting and analyzing real-world objects or environments using digital data against their possible shapes and appearances. The collected digital data is then processed using three-dimensional scanning software so that it can be used to create three-dimensional digital models. Therefore, the use of photogrammetric techniques can improve efficiency and accuracy in orthodontic treatment. Photogrammetry requires several stages and the necessary equipment to produce good results. Photogrammetry itself has advantages and disadvantages. The three-dimensional digital study model is a better alternative to the traditional study model because it is not susceptible to physical damage, requires small digital storage space, can be transmitted instantly electronically, is a means of educating patients, and can be manipulated virtually.
