“…The OS production using the CAD/CAM technology has some requirements as: data acquired directly through intraoral scanners or indirectly through a dental stone cast, software to design a virtual splint, and an additive manufacturing by 3-dimensional (3D) printing or a computerized milling device (Prpic et al, 2019). A full-arch dental impression using intraoral scanners has been shown to be quickly, and to increase treatment comfort and precision when compared to the irreversible hydrocolloid material (Ender & Mehl, 2015;Zimmermann et al, 2017).…”

“…The milled OS may have a better fit because of the lack of polymerization shrinkage (Huettig et al, 2017;Lutz et al, 2019;Al-Dwairi et al, 2020). Regardless of technology, the mechanical properties of OS depend more on the fabrication material (Prpic et al, 2019). For patients with bruxism, rigid splints are considered the better option.…”

“…For occlusal splint, a full-arch digital impressions are necessary, a specialized CAD software is used to design splints and a computerized milling device or 3-dimentional (3D) printing (Lauren & McIntyre, 2008;Ender & Mehl, 2015;Zimmermann, Koller, Rumetsch, Ender & Mehl, 2017;Prpic et al, 2019). The advantages of this technology is the capacity to store and reproduce the devices, accurate and consistent digital control over articulation, splint design and production and a quicker splint fabrication (Lauren & McIntyre, 2008;Waldecker et al, 2019;Vasques et al, 2020).…”

This dental technique note describes the manufacture of a new design of occlusal splint for protection of shear forces in anterior aesthetic restorations in patients with sleep bruxism, using the computer-aided design and computer-aided manufacturing (CAD/CAM) technique. Maxillary and mandibular arches were scanned and a Jig with polyvinyl siloxane material was made to maxillomandibular relationship record. For interocclusal device planning, the anterior limits must not cover the buccal surfaces of the anterior teeth, extending only on the incisal of these dental elements. The device is then virtually designed, and the CAD file of splint is sent to CAM milling process. The occlusal splint was tested for stability, insertion and removal, the distribution of occlusal contacts and care instructions were given to the patient. This device design avoids contact between splint and anterior aesthetic restorations during occlusal forces decreasing potential of failure, which increases the success rate of these previous aesthetic rehabilitations.

“…Creep susceptibility to polymeric materials is a subject of scientific research because creep is an immanent feature of many polymeric materials [43,44]. Currently, polymeric materials based on acrylic resins (PMMA) are widely used in the construction of mobile orthodontic appliances and other dental devices [11,[45][46][47]. It is expected that materials used for orthodontic products should have durability and dimensional stability during their clinical life.…”

Bending Behaviour of Polymeric Materials Used on Biomechanics Orthodontic Appliances

This paper discusses the issues of strength and creep of polymeric materials used in orthodontic appliances. Orthodontic biomechanics is focused on the movement of individual teeth or dental groups as a result of the force applied by orthodontic appliances. Stresses in the construction of functional and biomechanical appliances is generated when using the apparatus in the oral cavity. The orthodontic appliance must maintain its shape and not be damaged during treatment so strength and creep resistance are fundamental properties. It was assumed that the clinical success of orthodontic appliances can be determined by these performance properties. The aim of the work was the experimental assessment of comparative bending strength and creep resistance of selected popular polymer materials used in the production of biomechanical orthodontic appliances. Four commercial materials manufactured by the world class producers were tested: NextDent Ortho Rigid (Vertex-Dental B.V., Soesterberg, The Netherlands) marked as “1A”; Erkocryl (ERKODENT Erich Kopp GmbH, Pfalzgrafenweiler, Germany)-“2A”; Vertex Orthoplast (Vertex Dental B.V.), blue, marked as “3A” and material with the same name as “3A” but orange, marked in the article as “4A”. All the tests were carried out after aging in artificial saliva for 48 h at a temperature of 37 °C. Flexular strength and flexular modulus were made using the three point bending method according to the ISO 178 technical standard. Creep tests were carried out according to the method contained in ISO 899-2. The creep test was carried out in an artificial saliva bath at 37 °C. The creep tests showed significant differences in the strength, modulus and deformability of the tested materials. The strength reliability of the tested materials also varied. The research shows that the 2A material can be used for orthodontic applications in which long-term stresses should be lower than 20 MPa.
