INTRODUCTION: A rapidly advancing digital technology in orthodontics is 3-dimensional (3D) modeling and printing, prompting a transition from a more traditional clinical workflow toward an almost exclusively digital format. There is limited literature on the accuracy of the 3D printed dental models. The aim of this study was to assess the accuracy of 2 types of 3D printing techniques. METHODS: Digital and alginate impressions of the oral environment were collected from 30 patients...

Prader-Willi syndrome (PWS) is a complex disorder that affects multiple systems and may cause craniofacial and dentofacial abnormalities. However, there is still a lack of evidence in the literature regarding the progress of orthodontic treatment in patients with PWS. This case report describes the successful orthodontic treatment of a patient with PWS. A girl, 9 years 0 months of age, who had been diagnosed with PWS had protruding maxillary incisors and a convex profile. Her malocclusion was due to the posteriorly positioned mandible...

A 15-year-old girl with a convex profile and a retrognathic chin was referred for improvement of her profile. Nonextraction orthodontic therapy with temporary skeletal anchorage devices was used to improve her facial balance in a total active treatment time of 26 months. Her occlusion and profile were significantly improved by the treatment. Posttreatment records after 12 months showed excellent results with good occlusion and facial harmony.

RANDOMIZED CONTROLLED TRIAL
Turkan Sezen Erhamza, Ferabi Erhan Ozdıler
INTRODUCTION: The objective of this study was to evaluate the effect of rapid maxillary expansion (RME) on halitosis. METHODS: Thirty children (11-15 years old) were randomly divided into RME and control groups. The RME group consisted of 15 children treated with hyrax appliances, and the control group included 15 children without treatment. Halitosis was evaluated with the halimeter and the organoleptic method. Plaque index and gingival index scores were recorded...

INTRODUCTION: One nonsurgical treatment method for a patient with open bite is to use curved nickel-titanium arches and anterior elastics. The aim of this study was to investigate the effects of this technique with cone-beam computed tomography. METHODS: Eighteen open-bite patients' treatment records were used for this retrospective study. The treatment methods were identical for all patients, beginning with the levelling and alignment of the teeth and the placement of maxillary accentuated and mandibular reverse curved archwires with anterior elastics...

INTRODUCTION: The aims of this longitudinal analysis of untreated monozygotic twins were to investigate the change of the facial soft tissues during growth, to determine the concordance of soft tissue growth patterns between genetically identical twins, and to assess the genetic component of soft tissue development. METHODS: The sample consisted of 33 pairs of untreated monozygotic twins (23 male, 10 female) from the Forsyth Moorrees Twin Study (1959-1975); lateral cephalograms taken from 6 to 18 years of age were analyzed at 3-year intervals...

INTRODUCTION: Orthodontic space closure after premolar extraction commonly results in the formation of a gingival cleft, which may contribute to orthodontic relapse and poor periodontal health. The purpose of this study was to examine clinical parameters that may predispose patients to gingival clefts. METHODS: Twenty-nine patients planned for treatment with premolar extractions (n = 87) and orthodontic space closure were evaluated in this prospective study. The clinical measures included width of keratinized buccal gingiva, thickness of buccal gingiva, thickness of buccal bone, time of space closure, and the occurrence (presence or absence) and severity (volume) of cleft formation...

INTRODUCTION: Force application (FA) during orthodontic tooth movement is mediated through periodontal ligament (PDL) fibroblasts. FA on deciduous teeth has an inherent risk of root resorption, which is less in permanent teeth. Currently, the root resorption mechanism is poorly understood. We hypothesized that FA alters the morphology and gene expression of PDL fibroblasts. This study was designed to achieve homogenous PDL fibroblast cultures, establish an in-vitro FA model, analyze fibroblast morphology after FA, and compare the gene expressions of PDL fibroblasts of deciduous and permanent teeth after FA...

INTRODUCTION: The aims of this study were to investigate the eruption pattern of maxillary permanent canines in the alveolar cleft area after secondary alveolar bone grafting and to assess the risk indicators for canine impaction. METHODS: The sample consisted of 75 patients with unilateral cleft lip and palate who underwent secondary alveolar bone grafting with rhBMP-2 with a mean age of 9.8 years of age at 1 center. A split-mouth study design was used, with the noncleft hemiarch comprising the control group...

INTRODUCTION: The aim of this study was to compare the root resorption (RR) of maxillary incisors after traction of unilateral vs bilateral impacted canines with reinforced anchorage. METHODS: This retrospective longitudinal study included 60 cone-beam computed tomography scans of patients with maxillary impacted canines: 30 scans taken before and 30 taken after orthodontic traction with nickel-titanium coil springs. Two groups were formed according to the impaction condition: 15 with unilateral maxillary impacted canines and 15 with bilateral maxillary impacted canines...

MULTICENTER STUDY

INTRODUCTION: Our objectives were to assess patient satisfaction and quality of life among adults via 2 validated comprehensive questionnaires and to compare patient satisfaction and status in oral health-related quality of life immediately after orthodontic treatment in patients treated with Invisalign (Align Technology, San Jose, Calif) and those who received standard bracket-based treatment. METHODS: Adult patients (n = 145) treated with bracket-based or Invisalign therapy were recruited from several private practices and a university clinic...

INTRODUCTION: Our aim was to compare the load systems produced by rectangular loops and continuous arch mechanics on intrusion of a maxillary second molar. METHODS: An orthodontic appliance was passively bonded from second molar to second molar on a patient's model fixed to an orthodontic force tester. The second molars were extruded by 3 mm, and 2 mechanics systems were compared: beta-titanium rectangular loops and super-elastic nickel-titanium continuous arch...

RANDOMIZED CONTROLLED TRIAL
Thorsten Grünheid, Brent E Larson
INTRODUCTION: A new flash-free adhesive promises to eliminate the flash removal step in bonding and to reduce bonding time by as much as 40% per bracket, with a bond failure rate of less than 2%. The aim of this trial was to compare bonding time and bracket failure rate over a 1-year period between the flash-free adhesive and a conventional adhesive for orthodontic bracket bonding. METHODS: Forty-five consecutive patients had their maxillary incisors, canines, and premolars bonded with ceramic brackets (Clarity Advanced; 3M Unitek, Monrovia, Calif) using a flash-free adhesive (APC Flash-Free Adhesive Appliance System; 3M Unitek) on 1 side and a conventional adhesive (APCII Adhesive Appliance System; 3M Unitek) on the other side...
