The use of metal-free thermoplastic materials plays a key role in the orthodontic digital workflow due to increasing demand for clear aligner treatments. Three polymers commonly used fabricate aligners, namely Duran®, Biolon® and Zendura®, were investigated evaluate effect thermoforming (T.), storage artificial saliva (S.A.S.) their combination on mechanical properties. Elastic modulus yield stress specimens characterized. Each material was characterized each condition through tensile tests...
Abstract Background Clear aligners (CA) are among the most chosen orthodontic therapies for patients who require an invisible treatment. Previous studies showed that thermoforming process and complexity of intraoral environment might alter properties these devices. The aim current prospective clinical study was to assess thickness changes CA after 10 days use. secondary reproducibility process, in terms aligner thickness. Materials methods from 18 consecutive (13 women, 5 men, mean age 28.8...
Transparent and removable aligners represent an effective solution to correct various orthodontic malocclusions through minimally invasive procedures. An aligner-based treatment requires patients sequentially wear dentition-mating shells obtained by thermoforming polymeric disks on reference dental models. aligner is shaped introducing a geometrical mismatch with respect the actual tooth positions induce loading system, which moves target teeth toward positions. The common practice based...
ABSTRACT Objectives: To investigate the in vitro cytotoxicity of different thermoplastic materials for clear aligners on human primary gingival fibroblasts (HGFs). Materials and Methods: Four were considered this study: Duran (Scheu-Dental GmbH, Iserlohn, Germany), Biolon (Dreve Dentamid Unna, Zendura (Bay LLC, Fremont, CA, USA), SmartTrack (Align Technology, San Jose, USA). Three out four (Duran, Biolon, Zendura) assessed as thermoformed nonthermoformed, whereas was only thermoformed. The...
Aim . To evaluate the biomechanical effects of four different auxiliary-aligner combinations for extrusion a maxillary central incisor and to define most effective design through finite element analysis (FEA). Materials Methods A full arch (14 teeth) was modelled by combining two imaging techniques: cone beam computed tomography surface-structured light scan. The appliance auxiliary geometries were created exploiting computer-aided (CAD) procedures. reconstructed digital models imported...
Dedicated imaging methods are among the most important tools of modern computer-aided medical applications. In last few years, cone beam computed tomography (CBCT) has gained popularity in digital dentistry for 3D jawbones and teeth. However, anatomy a maxillofacial region complicates assessment tooth geometry anatomical location when using standard orthogonal views CT data set. particular, is defined by sub-region, which cannot be easily separated from surrounding tissues only considering...
Recent advances in Additive Manufacturing (AM) technologies have allowed a widespread diffusion of their use different fields. 3D printing is becoming commonplace for biomedical applications requiring the custom fabrication prostheses and appliances fitting patient-specific anatomies. In this work, feasibility vat photopolymerization technology, based on Digital Light Processing (DLP), has been investigated manufacturing polymeric orthodontic appliances. A DLP printer developed by exploiting...
A precise placement of dental implants is a crucial step to optimize both prosthetic aspects and functional constraints. In this context, the use virtual guiding systems has been recognized as fundamental tool control ideal implant position. particular, complex periodontal surgeries can be performed using preoperative planning based on CT data. The critical point procedure relies lack accuracy in transferring information surgical field through custom-made stereo-lithographic guides.In work,...
In the field of dental health care, plaster models combined with 2D radiographs are widely used in clinical practice for orthodontic diagnoses. However, complex malocclusions can be better analyzed by exploiting 3D digital models, which allow virtual simulations and treatment planning processes. this paper, data captured independent imaging sensors fused to create multi-body composed teeth, oral soft tissues alveolar bone structures. The methodology is based on integrating Cone-Beam Computed...
Chronic wounds represent a particular debilitating health care problem, mainly affecting elderly people. A full and correct diagnosis of tissue damage should be carried out considering both dimensional, chromatic, thermal parameters. great variety methods have been proposed with the aim producing objective assessment skin lesions, but none existing technologies seem to robust enough work for all ulcer typologies. This paper describes an innovative non-invasive system that allows automatic...
Abstract The 3D reconstruction of upper limb anatomy plays a significant role in many biomedical fields such as ergonomics, motion rehabilitation, and prosthesis design. In the last few years, technical advancement consumer-grade depth cameras has supported development portable low-cost optical body scanners for healthcare applications. real-time scanning human parts, however, still represents complex task due to non-stationary nature target. This issue imposes that time must be reduced much...
