“…When evaluating the tooth regions, three regions were defined: the incisor, premolar, and molar regions. Teeth 11,12,13,21,22,23,31,32,33,41,42,and 43 were in the incisor region, teeth 14, 15, 24, 25, 34, 35, 44, and 45 were in the premolar region, and teeth 16, 17, 26, 27, 36, 37, 46, and 47 were in the molar region (the third molar teeth were not included). The mean age value was taken as a reference when defining age groups.…”

“…In addition, the role of CBCT in oral, dental, and maxillofacial surgery, orthodontics, airway assessment, temporomandibular joint disorders, endodontics, and periodontology appears to be important [10,11]. Measurements and evaluations performed with CBCT enable the determination of the length of the edentulous area, alveolar bone thickness, and crest height [12,13]. One of the advantages of CBCT for orthodontic purposes relates to its ability to provide images of the alveolar bone surrounding the teeth buccally and lingually.…”

In the literature, there are no studies evaluating alveolar bone width in areas with a single missing tooth in terms of orthodontic tooth movement. This study was meant to determine whether residual alveolar bone width in edentulous crests is a risk factor for orthodontic tooth movement. The aim of this study was to evaluate the change in the residual alveolar bone width in the edentulous region compared to the alveolar bone width on the symmetrical toothed side using CBCT in individuals with a single missing tooth in whom orthodontic tooth movement was planned. This retrospective radiographic study was performed using CBCT images that were taken before orthodontic treatment for the evaluation of the edentulous area between January 2010 and January 2022. Individuals without any systemic disease aged 18 years or older whose edentulous area was restricted to one tooth were included in this study. Bone measurements were made on cross-sectional CBCT images. Of the 265 individuals participating in this study, 129 were male and 136 were female, with a mean age of 32.67 ± 6.50 years. The distribution of 265 edentulous regions (caused by 265 tooth extractions) was as follows: 23 were in the incisor region, 54 were in the premolar region, and 188 were in the molar region. The molar region had the highest bone width among the edentulous regions (p < 0.01). Bone widths were smaller in the edentulous crests for all regions (p < 0.01). In this study, it was determined that the bone width in the areas with a single missing tooth was insufficient, and this is a risk factor for orthodontic treatment.

“…Despite robust justification of CBCT in selected cases, some authors found insignificant differences in treatment planning decisions when CBCT was used versus conventional imaging [98], and others have stated that, even though CBCT may alter treatment planning, it does not necessarily improve or change orthodontic treatment outcome [99,100,101]. It is difficult to assess the exact value of CBCT with regards to changing the orthodontic treatment outcome because the evidence on CBCT efficacy and diagnostic value is not obtained from randomized controlled trials, but rather mostly from observational studies or studies with variable hierarchy of evidence [102,103].…”

Unlike patients receiving implants or endodontic treatment, most orthodontic patients are children who are particularly sensitive to ionizing radiation. Cone-beam computed tomography (CBCT) carries risks and benefits in orthodontics. The principal risks and limitations include ionizing radiation, the presence of artifacts, higher cost, limited accessibility, and the need for additional training. However, this imaging modality has several recognized indications in orthodontics, such as the assessment of impacted and ectopic teeth, assessment of pharyngeal airway, assessment of mini-implant sites, evaluation of craniofacial abnormalities, evaluation of sinus anatomy or pathology, evaluation of root resorption, evaluation of the cortical bone plate, and orthognathic surgery planning and evaluation. CBCT is particularly justified when it brings a benefit to the patient or changes the outcome of the treatment when compared with conventional imaging techniques. Therefore, CBCT should be considered for clinical orthodontics for selected patients. Prescription of CBCT requires judicious and sound clinical judgment. The central question of this narrative review article is: when does CBCT add value to the practice of orthodontics? To answer this question, this article presents discussion on radiation dosage of CBCT and other imaging techniques used in orthodontics, limitations of CBCT in orthodontics, justifying the use of CBCT in orthodontics, and the benefits and evidence-based indications of CBCT in orthodontics. This review summarizes the central themes and topics in the literature regarding CBCT in orthodontics and presents ten orthodontic cases in which CBCT proved to be valuable.
