Predictability of incisal labiolingual inclination, overjet, and overbite changes, and the prevalence of open gingival embrasures in patients with mandibular incisor extraction treated with Invisalign: A retrospective cohort study. This retrospective study aimed to assess differences between the planned Invisalign (Align Technology, San Jose, Calif) ClinCheck tooth movements and the achieved outcomes for patients with single mandibular incisor extraction with respect to overjet, overbite, and labiolingual inclination for the initial series of aligners and to assess the prevalence of open gingival embrasures (OGEs) in the former extraction sites. The records of 83 patients who received Invisalign treatment with extraction of a single mandibular incisor were evaluated. The predicted

Deep overbite reduction in adolescent patients treated with Invisalign: A retrospective analysis. Data regarding the efficacy of deep overbite correction with clear aligner therapy in adolescent patients are lacking. This study aimed to investigate the efficacy of deep overbite reduction in adolescent patients treated with Invisalign (Align Technology, San Jose, Calif) aligners . This retrospective study investigated a sample of 102 patients aged 10-17 years from a large database. All patients had completed wear of a prescribed series of Invisalign aligners with planned overbite reduction on a nonextraction basis. The predicted, pretreatment, and posttreatment overbite measurement values were obtained from Align Technology's ClinCheck digital facility. Linear modeling, with Bland-Altman

Investigating the Effectiveness of Low-Level Laser in Reducing Root Resorption of the Upper Incisors During Intrusion Movement Using Mini-Implants in Adult Patients With Deep Overbite: A Randomized Controlled Clinical Trial. Deep bite is a common characteristic of malocclusion, and many methods are used to treat it, including mini-implants used for the intrusion of the upper incisors in reducing the risk of OIIRR have been limited. This trial aimed to investigate the effectiveness of LLLT in reducing the resorption of the roots of the upper incisors during their intrusion in the context of deep bite correction. Thirty patients (13 males, 17 females; mean age 22.4±3.37 years) with deep overbite were recruited and allocated to the laser or the control groups. Mini-implants were inserted

Predictability of the deep overbite correction using clear aligners. The objective of this study was to investigate the predictability of overbite correction in patients with deepbite using the clear aligners (Invisalign, Align Technology, San Jose, Calif) and examine the accuracy of vertical movement and inclination change of individual teeth. This retrospective study included 24 deepbite patients (10 males and 14 females; aged 32.8 ± 11.9 years; an initial overbite of 5.20 ± 0.95 mm; an average treatment period of 11.04 ± 4.14 months) consecutively treated from September 2016 and completed before August 2021. SmartTrack materials were used for all patients. The initial, predicted, and achieved final models were exported from ClinCheck and superimposed via best-fit surface-based

[Clinical study of the effect of combined orthodontic and restoration treatment for introverted deep overbite patients with severe wear]. To investigate the effectiveness of combined orthodontic and restoration treatment for introverted deep overbite patients with severe wear. A total of 86 introverted deep overbite patients with severe wear admitted to Cangzhou People's Hospital from December function, tooth occlusion and chewing efficiency significantly increased (P＜0.05). Both orthodontic treatment and combined orthodontic and restoration treatment can be used to treat introverted deep overbite patients with severe wear. However, combination of orthodontic and restoration treatment has significant advantages.

Predictability of overbite control with the Invisalign appliance comparing SmartTrack with precision bite ramps to EX30. Although the Invisalign appliance has reported difficulty in achieving the overbite outcomes predicted by ClinCheck software (Align Technology, Santa Clara, Calif), the effect of modifications to the material and components of the appliance are largely unquantified. This study aimed to investigate and determine the accuracy of Invisalign in correcting a deep overbite by comparing the predicted outcome from ClinCheck to the achieved posttreatment outcome for treatment groups that use different components of the appliance system. A retrospective study was conducted using pretreatment and posttreatment intraoral scans and predicted outcomes (ClinCheck) stereolithography files

Comparison of clinical outcomes between Invisalign and conventional fixed appliance therapies in adult patients with severe deep overbite treated with nonextraction. The use of aligner therapy for orthodontic treatment has increased substantially in the past decade. However, no study has compared treatment outcomes between the conventional fixed appliance and Invisalign therapies in patients with a severe deep overbite. This study included 50 consecutive adult patients who underwent treatment with either Invisalign (n = 25; mean age, 23.3 ± 8.5 years) or a conventional fixed appliance (n = 25; mean age, 23.1 ± 6.5 years) to correct overbite >5 mm and >60% deep overbite. Cephalometric analysis and peer assessment rating was used to compare the clinical outcome between groups. Cephalometric

A comparative study between the effect of reverse curve of Spee archwires and anterior bite turbos in the treatment of deep overbite cases. To compare deep overbite treatment using 0.016 × 0.022 nickel-titanium lower reverse curve of Spee archwire (LRCA) or metal anterior bite turbos (ABTs). 48 patients with deep overbite malocclusion were randomly allocated into two groups. Group I (age = 18.4 ± 2.8 years, overbite = 5.8 ± 0.6 mm) was treated with LRCA, while Group II (age = 18.2 ± 3.1 years, overbite = 5.2 ± 0.4 mm) was treated with ABTs bonded to the palatal surface of the upper central incisors. Two cephalograms were taken for each patient, at post-alignment stage (T1) and post-leveling stage (T2). The primary outcomes were the anteroposterior and vertical changes of the lower teeth

One versus two anterior miniscrews for correcting upper incisor overbite and angulation: a retrospective comparative study. Miniscrews are effective devices for performing upper incisor intrusion. Different mechanics can be applied depending on the treatment objectives. This study aimed to evaluate the efficacy of one or two anterior miniscrews for upper incisor correction in cases of overbite and angulation in adult patients. Forty-four adults with deep overbite were divided into two groups: group 1 was treated with one miniscrew between upper central incisors and group 2 with two miniscrews between upper lateral incisors and canines. Incisor intrusion and length were measured from lateral cephalograms before treatment, after treatment and at least 12 months into retention (T0, T1 and T2). Forces

Influence of overjet and overbite on soft tissue profile in mature adults: A cross-sectional population study. The aim of this study was to explore the association of soft tissue profile and severity of overbite and overjet in a large adult population. The study population consisted of 1630 adults (age, 46 years; 712 men, 919 women), all part of the Northern Finland Birth Cohort 1966. A clinical examination was performed on all subjects, including recording of overjet and overbite, and digital facial (frontal and profile) photographs were obtained. A multivariate regression model was developed to study the correlation of soft tissue measurements with overjet and overbite, considering the effect of sex. The regression model explained approximately 30% of the variability in overjet in our sample

Does overbite reduction affect smile esthetics? To compare the effects of two common methods of overbite reduction on smile esthetics. A prospective clinical trial was conducted with 32 patients in whom overbite reduction was achieved using a maxillary incisor intrusion arch (18 patients) or flat anterior bite plate (14 patients). Clinical and cephalometric records were compared pretreatment (T1 ), after overbite reduction (T2), and posttreatment (T3). Both treatment groups experienced a reduction in overbite and maxillary and mandibular incisor proclination during treatment (T1-T3). The center of resistance of the maxillary incisor and the incisal edge was significantly intruded in the intrusion arch group during overbite reduction (T1-T2). However, most of the intrusion of the center

Dentoskeletal morphology in adults with Class I, Class II Division 1, or Class II Division 2 malocclusion with increased overbite. The treatment options for adults with increased overbite are limited to dentoalveolar changes that camouflage the condition. Because of high relapse tendency, defining the problem area is important when creating a treatment plan. This study aimed to evaluate dentoskeletal morphology in skeletal Class I and II anomalies associated with Angle Class I, Class II Division 1 (Class II/1), and Class II Division 2 (Class II/2) malocclusions with increased overbite compared with normal occlusion. Pretreatment cephalograms of 306 patients (131 men, 175 women; overall ages 18-45 years) were evaluated. Four groups were constructed. Three groups had increased overbite (>4.5

Effect of posterior space discrepancy and third molar angulation on anterior overbite. In this study, we aimed to determine the effect of maxillary and mandibular posterior space discrepancies and third molar angulations on the overbite. Pretreatment lateral cephalograms of 131 subjects were analyzed. The sample included 83 open-bite and 48 deepbite subjects. A multiple regression analysis was used to evaluate the influence of maxillary and mandibular posterior space discrepancies and third molar angulations (predictor variables) on overbite. Correlations between posterior space discrepancy and third molar angulation, and correlations between predictor variables and dental angulation and height of posterior teeth and incisors were evaluated with the Pearson correlation coefficient

Miniscrew-assisted customized lingual appliances for predictable treatment of skeletal Class II malocclusion with severe deep overbite and overjet. This report describes the use of miniscrew-assisted customized lingual fixed appliances in a patient with severe skeletal Class II malocclusion. The patient was a 12-year-old Chinese girl with the chief complaint of protrusive lips and anterior teeth . Her diagnosis included a skeletal Class II relationship with maxillary protrusion, a backward-rotated mandible, a full Angle Class II molar relationship, and severe deep overjet and overbite. Four premolars were extracted, and miniscrew anchorage was placed in the maxillary posterior lingual segment to provide maximum anchorage and to achieve vertical control of the intruding molars. The customized

Management of overbite with the Invisalign appliance. Most of the published literature on the management of overbite with the Invisalign appliance (Align Technology, Santa Clara, Calif) consists of case reports and case series. In this retrospective study of 120 patients, we sought to assess the nature of overbite changes with the Invisalign appliance. Records were collected from 3 practitioners , all experienced with the Invisalign technique. The patients were consecutively treated adults (>18 years old) who underwent orthodontic treatment only with the Invisalign appliance. Patients with major transverse or anteroposterior changes or extraction treatment plans were excluded. The study sample included 68 patients with normal overbites, 40 with deepbites, and 12 with open bites. Their median
