Validity of digital analysis versus manual analysis on orthodontic casts.

Background: As artificial intelligence within digital processes continues to advance and replace conventional manual workflows, it is crucial that digital data are consistent with analog data. The aim was to evaluate the validity and time efficiency of digital cast analysis on digital models in comparison with the manual, gold standard, cast analysis on plaster models.

Methods: Cast analysis was performed on 30 patients in three various methods: manually measured variables on plaster models (MP), manually measured variables on digital three-dimensional models (MD), and automatically measured variables on digital three-dimensional models (AD) on digital models.

Treatment choice for first permanent molars affected with molar-incisor hypomineralization, in patients 7-8 years of age: a questionnaire study among Swedish general dentists, orthodontists, and pediatric dentists.

Purpose: The aim of this study was to investigate attitudes and preferred therapy choice for first permanent molars (FPM) with Molar-Incisor Hypomineralization (MIH).

Methods: An online questionnaire was sent out to general dentists (n = 559) working in the Public Dental Service in Region Västra Götaland, orthodontists (n = 293), and pediatric dentists (n = 156) (members from each interest association), in Sweden. The questionnaire contained three parts: general questions regarding the respondents, patient cases, and general questions regarding extraction of FPMs with MIH.

Survey on retention procedures and use of thermoplastic retainers among orthodontists in Norway, Sweden, and Denmark.

Background: Orthodontic retention is the most important factor after successful orthodontic treatment. The use of thermoplastic retainers has increased in recent years, but information is lacking about the product materials and orthodontists' awareness of the products they use. The aim of this survey was to map the retention protocols among Scandinavian orthodontists, particularly their use of thermoplastic retainers.

Early plaque formation on PTFE membranes with expanded or dense surface structures applied in the oral cavity of human volunteers.

Objectives: This clinical randomized study aimed to evaluate the early plaque formation on nonresorbable polytetrafluoroethylene (PTFE) membranes having either a dense (d-PTFE) or an expanded (e-PTFE) microstructure and exposed to the oral cavity.

Material And Methods: Twelve individuals were enrolled in this study. In a split-mouth design, five test membranes (e-PTFE) with a dual-layer configuration and five control membranes (d-PTFE) were bonded on the buccal surfaces of posterior teeth of each subject.

Effectiveness of prefabricated myofunctional appliances in the treatment of Class II division 1 malocclusion: a systematic review.

Background: Prefabricated myofunctional appliances (PMAs) are widely advocated for correcting Class II division I malocclusion. However, their effectiveness is associated with a high amount of uncertainty within contemporary literature.

Objectives: The aim of this review was to systematically examine the available literature regarding the effectiveness of PMAs in treating Class II division 1 malocclusion in children and adolescents.

A cost-minimization analysis of large overjet reduction with two removable functional appliances based on a randomized controlled trial.

Objective: The purpose of this study was to assess and relate the societal costs of reducing large overjet with a prefabricated functional appliance (PFA), or a slightly modified Andresen activator (AA), using a cost-minimization analysis (CMA).

Design, Settings, And Participants: A multicentre, prospective, randomized clinical trial was conducted with patients from 12 general dental practices. Ninety-seven patients with an Angle Class II, division 1 malocclusion, and an overjet of ≥6 mm were randomly allocated by lottery to treatment with either a PFA or an AA.

Discomfort, expectations, and experiences during treatment of large overjet with Andresen Activator or Prefabricated Functional Appliance: a questionnaire survey.

Background: The purpose of this study was to investigate the amount of functional and social discomfort experienced after 1 and 6 months of appliance wear, comparing a slightly modified Andresen Activator (AA) and a Prefabricated Functional Appliance (PFA).

Methods: Ninety-seven patients randomly selected by lottery in an AA (40 subjects), and a PFA (57 subjects) group, with an Angle Class II, Division 1 malocclusion, were eligible for the study. One month and 6 months after start of treatment, a questionnaire, addressing discomfort, perception of treatment need and outcome, was used.

Treatment of large overjet in Angle Class II: division 1 malocclusion with Andresen activators versus prefabricated functional appliances-a multicenter, randomized, controlled trial.

Objectives: The purpose of this study was to compare the clinical effectiveness in reducing large overjet between a prefabricated functional appliance (PFA) and a slightly modified Andresen activator (AA).

Setting And Sample Population: Public Dental Service, Gothenburg, Sweden.

Participants, Study Design, And Methods: A multicentre, prospective randomized clinical trial was conducted with patients from 12 general dental practices.

Adolescents' experiences of using removable functional appliances.

Objectives: The aim of this qualitative study was to explore and describe adolescents' experiences of treatment with removable functional appliances.

Setting And Sample Population: Public Dental Service, Gothenburg, Sweden.

Material And Methods: Individual interviews focusing on adolescents' experiences of using a removable functional appliance were held with 21 adolescents (12 girls and nine boys).
