The periodontal ligament-periosteum sandwich hypothesis: A thought experiment on fenestrations and dehiscences.

This article describes a hypothesis for bone recovery after iatrogenic dehiscences or fenestrations. When roots are moved out of the alveolar bone, the periodontal ligament and periosteum form a bilayer membrane (sandwich) over the exposed root. If the root is allowed to relapse back toward its original position, bone recovery will occur between the periodontal ligament and periosteum.

Treatment acceptance in adult patients with anterior open bite: A National Dental Practice-Based Research Network study.

Introduction: Orthodontists have many techniques to treat anterior open bites and must involve patients in making treatment decisions. This study aimed to investigate orthodontic treatment plan acceptance by United States adults with anterior open bites and to identify associations between treatment acceptance and patient demographics and dentofacial characteristics.

Methods: A prospective, observational cohort study enrolled the patients of 91 orthodontic providers.

Tensile forces in the neurovascular bundle: A contributor to orthodontic relapse?

Objectives: The aim of this study is to investigate the neurovascular bundle (NVB) as a potential orthodontic relapse factor. The mechanical properties and the forces generated in the NVB after orthodontic extrusion are explored.

Materials And Methods: Six NVBs branching from the inferior alveolar nerve to the apices of the mandibular canines and premolars of mature pigs were harvested.

Retention: taking a more active role.

Retention may be particularly challenging after the correction of specific malocclusion features, such as tooth rotations, open bite and expansion, which are all inherently unstable. In this article, some indications for active retention are reviewed by highlighting a variety of clinical techniques and appliances. Active retention is discussed in relation to preservation of tooth alignment and in the three planes of space: sagittal, vertical and transverse.

The National Dental Practice-Based Research Network Adult Anterior Open Bite Study: Treatment success.

Introduction: Anterior open bite (AOB) continues to be a challenging malocclusion for orthodontists to treat and retain long-term. There is no consensus on which treatment modality is most successful. This study reports on the overall success rate of AOB orthodontic treatment in the adult population across the United States, as well as 4 major treatment modalities and other factors that may influence treatment success.

The National Dental Practice-Based Research Network Adult Anterior Open Bite Study: Patient satisfaction with treatment.

Introduction: This article evaluates and reports on the satisfaction of adult patients across the United States who received orthodontic treatment for anterior open bite malocclusion. The factors that influence satisfaction are also described.

Methods: Practitioners were recruited from the National Dental Practice-Based Research Network.

Agreement of treatment recommendations based on digital vs plaster dental models.

Introduction: The purpose of this study was to investigate differences in orthodontists' treatment plans based on digital models compared with plaster models. Additionally, we assessed whether digital or plaster models influence the reliability of orthodontists' treatment plans, as well as the amount of time required to arrive at the plan.

Methods: Sixteen orthodontists planned treatment for 20 patients at 2 time points using either the same or different model formats (digital or plaster).

The National Dental Practice-Based Research Network adult anterior open bite study: A description of the practitioners and patients.

Objectives:: To describe the demographic and practice characteristics of the clinicians enrolled in a large, prospective cohort study examining recommendations and treatment for adult anterior open bite (AOB) and the relationship between these characteristics and practitioners' self-reported treatment preferences. The characteristics of the AOB patients recruited were also described.

Materials And Methods:: Practitioners were recruited from the National Dental Practice-Based Research Network.

Recommendations for clear aligner therapy using digital or plaster study casts.

Background: Clear aligner therapy has evolved considerably since its introduction 20 years ago. Clinicians have become more experienced with aligner therapy, but little is known about the types of malocclusions that clinicians currently treat with aligners. Similarly, it is not known if viewing digital vs plaster models has any impact on the treatment planning process for aligners.

Predicting improvement of postorthodontic white spot lesions.

Introduction: Patients undergoing orthodontic treatment are at greater risk for developing white spot lesions (WSLs). Although prevention is always the goal, WSLs continue to be a common sequela. For this reason, understanding the patterns of WSL improvement, if any, has great importance.

Retrospective investigation of the effects and efficiency of self-ligating and conventional brackets.

Introduction: The purpose of this retrospective cohort study was to assess the effects and efficiency of self-ligating brackets compared with conventional brackets. A secondary purpose was to identify the pretreatment factors associated with the choice of self-ligating or conventional brackets.

Methods: The subjects were treated by 2 private practitioners who used both self-ligating and conventional brackets in their practices.

Classification and treatment of Class II subdivision malocclusions.

Introduction: Patients with Class II subdivision malocclusions are a challenge for clinicians because reestablishing symmetry in 1 arch or both arches is often a treatment goal. In patients with mandibular skeletal asymmetry, surgery is often a treatment option. However, patients may be unwilling to undergo surgery, and other options might have to be considered.

A prospective study of clinical outcomes related to third molar removal or retention.

Objectives: We investigated outcomes of third molar removal or retention in adolescents and young adults.

Methods: We recruited patients aged 16 to 22 years from a dental practice-based research network in the Pacific Northwest from May 2009 through September 2010 who had at least 1 third molar present and had never undergone third molar removal. Data were acquired via questionnaire and clinical examination at baseline, periodic online questionnaires, and clinical examination at 24 months.

Recommendations for third molar removal: a practice-based cohort study.

Objectives: We investigated general dentists' reasons for recommending removal or retention of third molars and whether patients adhered to dentists' recommendations.

Methods: In a 2-year prospective cohort study (2009-2011) in the Pacific Northwest, we followed 801 patients aged 16 to 22 years from 50 general dental practices. Generalized estimating equations logistic regressions related patient and dentist characteristics to dentists' recommendations to remove third molars and to patient adherence.

Stability of deep-bite correction: A systematic review.

Objectives: Deep bite occurs in about 15% to 20% of the US population. Currently, it is unknown which types of correction are most efficient or stable. The purpose of this systematic review was to investigate factors related to stability of deep-bite correction.

Effectiveness of MI Paste Plus and PreviDent fluoride varnish for treatment of white spot lesions: a randomized controlled trial.

Introduction: White spot lesions are a common sequela of orthodontic therapy. In this parallel-group randomized trial, we assessed the effectiveness of 2 agents commonly used to ameliorate white spot lesions compared with a normal home-care regimen.

Methods: Patients aged 12 to 20 years were recruited from the offices of orthodontists and dentists who belonged to the Practice-based Research Collaborative in Evidence-based Dentistry network.

Long-term stability of anterior open-bite closure with bilateral sagittal split osteotomy.

Introduction: Maxillary impaction and bimaxillary osteotomies are used to treat anterior open-bite malocclusions but can have adverse soft-tissue effects. Correcting an anterior open bite with a single mandibular procedure avoids these undesirable soft-tissue effects, but the stability of this procedure is unknown. The purpose of this study was to assess the long-term stability of anterior open-bite correction with bilateral sagittal split osteotomy and rigid internal fixation.

Bisphosphonates as a risk factor for adverse orthodontic outcomes: a retrospective cohort study.

Introduction: Bisphosphonates are a class of drugs commonly prescribed to treat osteoporosis. They act by decreasing the resorption of bone. Since tooth movement depends on bone remodeling, these drugs can impact orthodontic treatment.

Medicaid and privately financed orthodontic patients have similar occlusal and psychosocial outcomes.

Objective: This study compares occlusal and psychosocial outcomes from comprehensive orthodontic treatment in Medicaid (MC) and privately financed (private pay, PP) patients.

Methods: Two cohorts received comprehensive orthodontics: MC (n = 66); PP (n = 60). A calibrated, blinded examiner scored dental casts at baseline (pretreatment, T1) and after completing 2 years of treatment (posttreatment, T2) using the Peer Assessment Rating (PAR) and the Index of Complexity, Outcome, and Need (ICON).

Stability of treatment for anterior open-bite malocclusion: a meta-analysis.

Introduction: Anterior open-bite (AOB) treatment is considered challenging because of difficulties in determining and addressing etiologic factors and the potential for relapse in the vertical dimension after treatment. In this review, we compiled evidence on the long-term stability of the major therapeutic interventions for correcting AOB. Our objective was to review and compile evidence for the stability of surgical and nonsurgical therapies for AOB malocclusion.
