Orthodontic management of anterior disc displacement without reduction.

This article presents a novel idea for managing patients with anterior disc displacement without reduction that often develops in susceptible patients during routine orthodontic treatment. The patient was a 24-year-old male who presented with class I right molar and canine relationship and class III left molar and canine relationship on a class I skeletal base, complaining of bimaxillary crowding. The case was treated with fixed orthodontic appliance with maxillary expansion and unilateral mandibular extraction to eliminate the mandibular crowding.

Comparative assessment of the cell-surface antigens and gene expression profiles of the gingival tissue biomarkers in subjects with fixed functional and removable functional orthodontic appliances.

Background: This study aimed to examine the cellular components of the gingiva during orthodontic treatment with fixed and removable appliances. The cellular and molecular cues of pathologies of the gingival tissue associated with the use of different orthodontic appliances could be studied.

Materials And Methods: Tissue samples of gingiva were received from healthy patients undergoing gingivectomy for aesthetic purpose and from patients with fixed and removable functional orthodontic appliances undergoing gingivectomy for gingival overgrowth.

Factors influencing the orthodontic treatment plan in Class II malocclusion.

Introduction: This study aimed to investigate the influence of orthodontists' demographics and patient characteristics on the orthodontic treatment plan decision for borderline Class II Division 1 malocclusion in growing patients.

Methods: An electronic survey was distributed to orthodontists through the American Association of Orthodontists. Participating orthodontists were asked to select their preferred orthodontic treatment plan for 3 patients with borderline Class II Division 1 malocclusion.

Combined Orthodontic and Surgical Management for Treatment of Severe Class III Malocclusion with Anterior and Posterior Crossbites.

Severe class III malocclusion can be a great challenge, especially in adult patients. This case report describes an adult patient with severe skeletal class III malocclusion and with an obvious maxillary deficiency and mandibular excess causing both anterior and posterior crossbites in addition to a shift in the upper and lower midlines to the left concerning the facial midline. This was complicated by compensatory mechanisms such as the proclination of upper incisors and retroclination of lower incisors.

Morphological features of Class I, II and III malocclusions of Saudi adolescents.

Aims: This cross-sectional study compared and contrasted the morphological characteristics of Class I, II and III malocclusions in an adolescent Saudi population.

Methods: Adolescent Saudis with Angle's Class I, II and III malocclusions were selected from orthodontic patients' records. Angular and linear measurements were compared between the three groups.

Anatomical consideration for optimal position of orthodontic miniscrews in the maxilla: a CBCT appraisal.

Background: Orthodontic miniscrews are commonly used as temporary anchorage devices. Bone thickness and bone depth are important factors when placing miniscrews. There are no studies to assess the maxillary bone thickness for optimum miniscrew placement in a Saudi population.

Radiographic evaluation of dental age maturity in 3-17-years-old saudi children as an indicator of chronological age.

Objective: This study was aimed to evaluate the dental age in Saudi children from panoramic radiographs using the Demirjian method to estimate their chronological age.

Materials And Methods: This retrospective cross-sectional study consisted of 1902 panoramic radiographs of 955 boys and 947 girls between the ages of 3-17 years. All children were placed in the age group closest to their chronological age.

Effect of lactic Acid etching on bonding effectiveness of orthodontic bracket after water storage.

Incisors' proportions in smile esthetics.

Aims: To determine whether alteration of the maxillary central and lateral incisors' length and width, respectively, would affect perceived smile esthetics and to validate the most esthetic length and width, respectively, for the central and lateral incisors.

Materials And Methods: Photographic manipulation was undertaken to produce two sets of photographs, each set of four photographs showing the altered width of the lateral incisor and length of the central length. The eight produced photographs were assessed by laypeople, dentists and orthodontists.

Surgical Orthodontic Treatment of Severe Skeletal Class II.

This paper describes an adult Saudi male patient who presented with a severe skeletal class II deformity. The case was managed with a combination of presurgical orthodontic treatment followed by a double jaw orthognathic surgery and then another phase of orthodontic treatment for final occlusal detailing. Extraction of the four first premolars was done during the presurgical orthodontic phase of treatment to decompensate upper and lower incisors and to give room for surgical setback of the maxillary anterior segment.

En masse retraction versus two-step retraction of anterior teeth in extraction treatment of bimaxillary protrusion.

In the present report, two techniques of space closure; two-step anterior teeth retraction (TSR) and en masse retraction (ER) were used in two adult patients who had bimaxillary protrusion and were treated with four premolar extractions and fixed orthodontic appliance therapy. Both patients had a Class I dental malocclusion and the same chief complaint, which is protrusive lips. Anterior teeth were retracted by two-step retraction; canine sliding followed by retraction of incisors with T-loop archwire in the first patient and by en masse retraction using Beta titanium alloy T-loop archwire in the second case.

Bacteria induce osteoclastogenesis via an osteoblast-independent pathway.

Bacteria or their products may cause chronic inflammation and subsequent bone loss. This inflammation and bone loss may be associated with significant morbidity in chronic otitis media, periodontitis, endodontic lesions, and loosening of orthopedic implants caused by lipopolysaccharide (LPS)-contaminated implant particles. Currently, it is not clear how bacteria or endotoxin-induced bone resorption occurs and what cell types are involved.
