The impact of COVID-19 pandemic on total treatment time of fixed appliances.

Background: Several aspects of the orthodontic routine seem to have been affected since the emergence of SARS-CoV-2. We aimed to evaluate the impact of the COVID-19 pandemic on the duration of fixed orthodontic treatment.

Methods: This retrospective study evaluated consecutive cases of patients undergoing fixed orthodontic treatment that completed treatment before (n = 37) or during (n = 26) the COVID-19 pandemic.

Prevalence of non-carious cervical lesions and orthodontic treatment: a retrospective study.

Background: This study aimed to assess the distribution of non-carious cervical lesions (NCCLs) by tooth type, investigate the prevalence of NCCLs in patients undergoing orthodontic treatment, and identify the possible associated factors.

Material And Methods: A total of 160 patients were enrolled in this retrospective study. Data on the following variables were collected from pre-and post-orthodontic treatment records: age, sex, Angle's malocclusion, facial pattern, number of activation sessions, compensatory treatment, and retreatment.

Evaluation of the condylar position in younger and older adults with or without temporomandibular symptoms by using cone beam computed tomography.

Statement Of Problem: Recent studies in young adults have questioned the influence of discrepancies between central and maximal intercuspal positions in temporomandibular disorders (TMDs). However, whether this finding was because this type of etiologic agent requires time for the development of changes in the condylar position is unclear.

Purpose: The purpose of this clinical study was to use cone beam computed tomography (CBCT) to evaluate the presence or absence of discrepancies between the centric relation (CR) and maximum intercuspation (MI) in younger and older adults in populations with or without TMDs.

Fractured alveolar process displacement evaluation-Effect of the rigidity of wire-composite splints.

Backgrounds/aims: Traumatic dental injuries with bone fractures require rigid splinting. The degree of rigidity of the wire-composite splints can be challenging. The aim of this study was to evaluate the effect of the rigidity of different wire-composite splints on alveolar process displacement.

Comparative analysis between mandibular positions in centric relation and maximum intercuspation by cone beam computed tomography (CONE-BEAM).

This research consisted of a quantitative assessment, and aimed to measure the possible discrepancies between the maxillomandibular positions for centric relation (CR) and maximum intercuspation (MI), using computed tomography volumetric cone beam (cone beam method). The sample of the study consisted of 10 asymptomatic young adult patients divided into two types of standard occlusion: normal occlusion and Angle Class I occlusion. In order to obtain the centric relation, a JIG device and mandible manipulation were used to deprogram the habitual conditions of the jaw.
