The Impact of Orthodontic Extrusion on Keratinized Gingiva.

: The key factor that enables osteoblastic activity and the formation of new bone, as well as gingiva, during orthodontic tooth extrusion (OE) is the periodontal ligament. The reaction of periodontal tissues associated with changes in the gingiva is a part of orthodontic tooth displacement. The aim of this study was to examine the effect of OE on the width of the zone of the keratinized and attached gingiva, the position of the mucogingival junction, and the height of the interdental papillae in the region where the OE was performed as well as in the adjacent region.

Comparing virtual setup software programs for clear aligner treatment.

Background: The aim of this study was to compare the outcomes of the same amount of tooth movement among four different virtual setup software programs.

Methods: This retrospective study included 32 patients who underwent Invisalign treatment. Patients' initial stereolithography (STL) files were imported to three different software programs (SureSmile Aligner [Dentsply Sirona, Charlotte, NC], Ortho Insight 3D [Motion View software, Chattanooga, TN], and Ortho Analyzer [3Shape, Copenhagen, Denmark]).

WNT10A and RUNX2 mutations associated with non-syndromic tooth agenesis.

The goal of this study was to examine the prevalence of WNT10A and RUNX2 mutations and assess their potential impact on the phenotype of non-syndromic tooth agenesis. The study included 30 participants with non-syndromic tooth agenesis, divided into hypodontia (n = 24) and oligodontia forms (n = 6), and 42 unaffected family members. Genomic DNA from buccal epithelial cells was used for polymerase chain reaction amplification of functionally important exons of the WNT10A and RUNX2 genes.

Comparing 3D Tooth Movement When Implementing the Same Virtual Setup on Different Software Packages.

Background/objectives: The purpose of this study was to compare the differences in tooth movements when implementing the same virtual setup on the following four different software packages: ClinCheck Pro, Ortho Analyzer, SureSmile, and Ortho Insight 3D.

Materials/methods: Twenty-five adult patients treated with Invisalign at the Case School of Dental Medicine (CWRU)'s department of orthodontics were retrospectively collected. Initial stereolithography (STL) files were obtained and imported into three software packages.

Impacts of childhood malocclusion on the family.

Purpose: To analyze the effects of children's malocclusions and associated quality of life on family relationships by evaluating psychometric characteristics of the Family Impact Scale (FIS) in adolescents seeking orthodontic treatment.

Materials And Methods: Included were 334 participants (children aged 11-14 years; 53% female and 47% male) and their parents (84% mothers, 16% fathers) who were recruited at two dental clinics in Croatia. The Child Perception Questionnaire, Parental-Caregiver Perception Questionnaire, and FIS were administered.

Predictors of patient compliance during Class II division 1 malocclusion functional orthodontic treatment.

Objectives: To determine factors that could predict Class II/1 malocclusion patient compliance during functional treatment.

Materials And Methods: The sample consisted of 77 subjects (aged 11-13 years; 47% girls) presenting with Class II/1 malocclusion. Inclusion criteria were distal molar relationship, overjet greater than 5 mm, and confirmed pubertal growth spurt.

Strategies for Managing the Risk of Mucogingival Changes During Impacted Maxillary Canine Treatment.

Gingival recession is a frequent mucogingival defect in the adult population. It affects the esthetics and is related to hypersensitivity and a high risk of periodontal attachment loss. The connection between orthodontic treatment and periodontal health has been debated for a long time.

Pharyngeal Airway Changes after Bimaxillary Orthognathic Surgery--Preliminary Results.

Introduction: Dentofacial deformity, a deviation from normal facial proportions and dental relationships, is corrected by jaw repositioning in all three spatial planes, which changes the position and tension of the surrounding tissues, bones and muscles. These changes may also affect the dimensions of the pharyngeal airways (PA).

Objective: The aim of this study was to evaluate and compare three-dimensional PA changes in patients treated by a combination mandibular set-back/maxillary advancement versus patients that had bimaxillary advancement with genioplasty.

Reliability of computerized cephalometric outcome predictions of mandibular set-back surgery.

Introduction: A successful treatment outcome in dentofacial deformity patients commonly requires combined orthodontic-surgical therapy. This enables us to overcome functional, aesthetic and psychological problems. Since most patients state aesthetics as the primary motive for seeking therapy, cephalometric predictions of treatment outcome have become the essential part of treatment planning, especially in combined orthodontic-surgical cases.

Association of fibronectin with hypogalactosylated immunoglobulin G in gingival crevicular fluid in periodontitis.

Background: Fibronectin (FN) can bind to immunoglobulins (Ig), influencing both the normal clearance and abnormal deposition of circulating immune complexes. This study focuses on the possible interaction between FN and IgG present in gingival crevicular fluid (GCF) of periodontitis patients and periodontally healthy controls, with the aim to determine whether such interaction may be connected with the glycosylation profile of IgG and, thus, consequentional in accumulation of proinflammatory IgG in periodontal pockets.

Methods: The study included 30 patients with initial or advanced periodontitis, and 13 periodontally healthy subjects.
