Collection description

The current definition of being “digital” is the “re-imagining of processes to be by default a fully online, fully automated process from end user interaction to back office processing, with no or minimal need for human intervention”[1]. Digital technology has begun to be a fundamental part of our daily life, starting from the use of smartphones to its use in medical diagnosis, treatment modalities, teaching and learning tools, and surgical techniques [2]. Digital technology in a dental practice started in 1974 with the introduction of computerized scheduling [3]. At the beginning, the approach of using digital technology was to increase the accuracy of the diagnosis; as a result, the workflow was simplified [4]. In the last thirty years, most dental offices and dental schools have begun to use clinical records, photographs and digital radiographs. Moreover, digital technology has evolved from two-dimensional visualization, based on photographs or drawings, to the possibility of exploring a patient in his three dimensions. Also, soft tissue analysis using 3D stereophotogrammetry (3D photos), intra-oral scans and three-dimensional radiography are rapidly replacing study casts and two dimensional radiography [2]. One of the benefit of the digitalizition is the opportunity to have high resolution images with low radiation obtained through the cone beam computed tomography, that is currently considered the preferred imaging modality in orthodontics [4]. In addition, digital technology in orthodontics allows to perform virtual treatment planning, as well as translate the plans into treatment execution with digitally driven appliance manufacture and placement using various CAD/CAM techniques from printed models, indirect bonding trays and custom made brackets to robotically bent wires. Moreover, it is also becoming possible to remotely monitor treatment and control it [2]. The virtual treatment planning not only allows the clinician to explore a number of treatment options in a simple manner, it also facilitates better communication with other dental professional especially in cases that require combined orthodontic and restorative treatment. Furthermore, it provides an effective communication with patients and allows them to visualize the treatment outcome and also understand the treatment process [2]. The aim of this PhD project was to study the use of digital technologies in the diagnosis, treatment planning and therapy of orthodontic patients. This thesis is composed of four studies. The aim of the first study was to perform a collaborative web service to support orthodontic treatments, using a collective of models, automatically generated, on the basis of different datasets, made by different scholars and practitioners at the School of Orthodontics of the University of Naples “Federico II”, in order to help in the diagnosis of the orthodontic patient. In chapter 2, it is reported a research on the association between gingival biotype and facial typology evaluated by means of a cephalometric and 3D facial analysis, in patients seeking an orthodontic treatment. The third study aimed to determine the distribution of the CoGoMe^, and its relationship with age, sagittal jaw relationship (ANPg^) and mandibular inclination (SN^GoGn) in a population of patients from Southern Italy. In chapter 4, it is described a research on the periodontal health of patients undergoing fixed orthodontic and clear aligner therapy with a supportive periodontal therapy after a 3-month follow-up.
