Objective: Owing to the availability of 3D software, scanners, and printers, clinicians are encouraged to produce in-office aligners. Recently, a new directprinting resin (Tera Harz TC-85DAC) has been introduced. Studies on its mechanical characteristics and biological effects have been published; however, evidence on its efficacy in orthodontic treatment remains scarce. This pilot study aimed to investigate the accuracy of teeth movement achieved with directprinted aligners. Methods: Seventeen patients (eight males and nine females) with a mean age of 27.67 ± 8.95 years, presenting with dental rotations < 30° and spaces/crowding < 5 mm, were recruited for this study. The teeth movement was planned starting from a T0 digital dental cast. The 3D direct-printed aligners were produced using Tera Harz TC-85DAC resin. Once the orthodontic treatment was completed, a final digital cast was obtained (T1). The planned teeth positions were then superimposed onto the T0 and T1 digital models.The differences between the programmed movements and the achieved overall torque, tip, rotation, and transverse dimensions were assessed using the paired t test or Wilcoxon’s signed rank test. Results: The overall accuracies for torque, tip, and rotation were 67.6%, 64.2%, and 72.0%, respectively. The accuracy of the change in transverse diameter was 99.6%. Conclusions Within the limits of the present pilot study (difficulties with abnormally shaped teeth and use of attachments), it can be concluded that 3D printed aligners can be successfully printed in-house and utilized for mildly crowded cases, with a comparable accuracy of tooth movement to that of other aligners.

Objective: Current nosology redefined agoraphobia as an autonomous diagnosis distinct from panic disorder. We investigated the lifetime prevalence of agoraphobia, its association with other mental disorders, and its impact on the health-related quality of life (HR-QoL). Methods: Community survey in 2,338 randomly selected adult subjects. Participants were interviewed with the Advanced Neuropsychiatric Tools and Assessment Schedule (ANTAS), administered by clinicians. The diagnoses were based on the ICD-10 criteria. The Short-Form Health Survey (SF-12) was used to quantify HR-QoL. Results: In the sample, 35 subjects met the criteria for agoraphobia (1.5%), with greater prevalence among women (2.0%) than men (0.9%): odds ratio (OR) 2.23; 95% CI: 1.0-5–2. Agoraphobia was more often seen among those with (n=26; 1.1%) than without (n=9; 0.4%) panic disorder: OR=8.3; 2.9–24.4. Co-morbidity with other mental disorders was substantial. The mean score of SF-12 in people with agoraphobia was 35.2±7.8, with similar levels of HR-QoL in people with (35.3±7.9) or without (34.8±7.3) panic disorder: ANOVA: F(1;33)=0.0; p=1.00. Conclusion One out of seventy people may suffer from agoraphobia in their lifetime. The attributable burden in terms of HR-QoL is substantial and comparable to the one observed for chronic mental disorders such as major depression, post-traumatic stress disorder, or obsessive-compulsive disorder.
