Intrusion Of Incisors Research Articles

Esthetic Improvement through Orthodontic Treatment Involving Extraction: Use of Orthodontic Anchor Screws.

Here, we report two cases of dental bimaxillary protrusion in which orthodontic anchor screws were used to improve the esthetics of the mouth and lips and facilitate complete closure of the mouth. Case 1 was a woman with dental maxillary protrusion and constriction of the dental arches, with the main complaint of protrusion of the lips and mandibular crowding. The maxillary and mandibular dental arches were first widened and traction applied to the maxilla via orthodontic anchor screws. The maxillary incisors were retracted 10 mm and the mandibular incisors 3 mm, resulting in upper lip retraction of 3 mm and bottom lip retraction of 5 mm with respect to the E-line. The nasolabial angle increased to 20°, and the inter-vermilion angle, which indicates the thickness of the vermillion, decreased to 20°, improving esthetics by reducing the thickness of the lips. Case 2 was a woman with bimaxillary dental protrusion, with the chief complaint of protruding lips and a gummy smile. Orthodontic anchor screws were used to achieve posterior traction and intrusion in the maxillary incisor region to improve the gummy smile. The maxillary incisors were retracted 9 mm and the mandibular incisors 8 mm. In the soft tissues, this yielded upper lip retraction of 3 mm and bottom lip retraction of 4 mm with respect to the E-line. The nasolabial angle increased to 10° and the inter-vermilion angle decreased to 30°, improving esthetics by reducing the thickness of the lips. The gummy smile was also improved, with 4 mm intrusion of the maxillary incisors. Increased ease in closing of the mouth was also a major factor in patient satisfaction with the results of orthodontic treatment.

Cone-beam computed tomography-based diagnosis and treatment simulation for a patient with a protrusive profile and a gummy smile

For patients with bimaxillary protrusion, significant retraction and intrusion of the anterior teeth are sometimes essential to improve the facial profile. However, severe root resorption of the maxillary incisors occasionally occurs after treatment because of various factors. For instance, it has been reported that approximation or invasion of the incisive canal by the anterior tooth roots during retraction may cause apical root damage. Thus, determination of the position of the maxillary incisors is key for orthodontic diagnosis and treatment planning in such cases. Cone-beam computed tomography (CBCT) may be useful for simulating the post-treatment position of the maxillary incisors and surrounding structures in order to ensure safe teeth movement. Here, we present a case of Class II malocclusion with bimaxillary protrusion, wherein apical root damage due to treatment was minimized by pretreatment evaluation of the anatomical structures and simulation of the maxillary central incisor movement using CBCT. Considerable retraction and intrusion of the maxillary incisors, which resulted in a significant improvement in the facial profile and smile, were achieved without severe root resorption. Our findings suggest that CBCT-based diagnosis and treatment simulation may facilitate safe and dynamic orthodontic tooth movement, particularly in patients requiring maximum anterior tooth retraction.

Maxillary incisors changes during space closure with conventional and skeletal anchorage methods: a systematic review.

The objective of this systematic review was to compare the antero-posterior, vertical and angular changes of maxillary incisors with conventional anchorage control techniques and mini-implant based space closure methods. The electronic databases Pubmed, Scopus, ISI Web of knowledge, Cochrane Library and Open Grey were searched for potentially eligible studies using a set of predetermined keywords. Full texts meeting the inclusion criteria as well as their references were manually searched. The primary outcome data (linear, angular, and vertical maxillary incisor changes) and secondary outcome data (overbite changes, soft tissue changes, biomechanical factors, root resorption and treatment duration) were extracted from the selected articles and entered into spreadsheets based on the type of anchorage used. The methodological quality of each study was assessed. Six studies met the inclusion criteria. The amount of incisor retraction was greater with buccally placed mini-implants than conventional anchorage techniques. The incisor retraction with indirect anchorage from palatal mini-implants was less when compared with buccally placed mini-implants. Incisor intrusion occurred with buccal mini-implants, whereas extrusion was seen with conventional anchorage. Limited data on the biomechanical variables or adverse effects such as root resorption were reported in these studies. More RCT's that take in to account relevant biomechanical variables and employ three-dimensional quantification of tooth movements are required to provide information on incisor changes during space closure.

Skeletal Anchorage for the Correction of Bimaxillary Protrusion and Gummy Smile

Many methods of achieving maximum anchorage have been experimented by various clinicians through the years. Usage of mini implants has its own limitations, inconsistent results being the most common. However, anchorage using mini plates produced consistent results even though it requires a minor invasive surgical procedure. The aim was to retract and correct a gummy smile of 5 mm, diagnosed to be due to a vertical maxillary excess, with mini plates used bilaterally in the zygomatic buttress region. A modified “L” shaped surgical stainless steel mini plate was inserted and stabilized with 3 screws in the anterior region of the zygomatic buttress and sutured with the tip of the surgical plate exposed in the oral cavity for the attachment of an elastomeric chain to the arch wire. The gummy smile was fully corrected with minimal intrusion of maxillary anteriors. Cephalometrically, there was intrusion and retraction of maxillary incisors with absolutely no anchor loss. The modified surgical mini plate is an excellent tool for the successful correction of the gummy smile and also has proved to be a very efficient absolute anchorage system for en masse retraction.

Treatment of Class II, Division 2 Malocclusion with Miniscrew Supported En-Masse Retraction: Is Deepbite Really an Obstacle for Extraction Treatment?

A 17-year-old female patient, whose chief complaint was her unpleasing smile, had skeletal and dental class II malocclusion, hypodivergent facial type with a severely increased overbite. Among the treatment options, upper-first-premolar extractions followed by miniscrew-supported en-masse retraction was the treatment of choice. After the initial levelling and alignment, miniscrews with 1.5- to 1.4-mm diameter and 7-mm lenght, were installed between the roots of the second premolars and the first molars, bilaterally. En-masse retraction was achieved on a 0.016×0.022-inch stainless steel archwire with 7-mm long power hooks placed distal to the lateral incisors, and with nickel-titanium (NiTi) closed coil springs exerting 250-gr of force per side. At the end of the treatment, deepbite, incisor inclinations and interincisal angle were corrected, and Class II molar relationship with good intercuspation was achieved. Upper 2-2, lower 3-3 retainers were bonded for retention. As a result, deepbite and Class II canine relationship was successfully corrected with simultaneous incisor intrusion and retraction using miniscrew-supported en-masse retraction.

Invisible orthodontics: clear aligners and customized lingual appliances

In recent years, invisible orthodontics has been one of the concerns of both orthodontists and patients. As two types of invisible orthodontics, clear aligners fit for cases that have high demand for living quality, need distalization of molars or intrusion of incisors, suffer from severe periodontitis, or that have non-abundant time for visits. While customized lingual appliances fit for cases that have high demand for aesthetics, have deep overbite or complex malocclusion, need maxillary expansion or retraction of incisors, or that have low compliance and good economic conditions. Based on aspects of clinical application, this article presents the characteristics of these two types of invisible orthodontics, in order to provide reference for individualized options according to different situations.

Orthodontic intrusion of periodontally-compromised maxillary incisors: 3-dimensional finite element method analysis.

Loading of the compromised periodontium with orthodontic forces produces different results than those achieved in patients with healthy periodontal support. Determining the force value at a level preventing further deterioration of the patient's periodontal status, thus delivering the most precisely individualized "dose" of loading, seems to be crucial for the successful intrusion of teeth with reduced periodontal support. The aim of the study was to determine the range of force values efficiently intruding maxillary incisors without further compromising the initially-impaired periodontal status. Finite element analysis (FEA), allowing estimation of the stress and strain distribution, was the method of choice. The CT scans of a periodontally-compromised patient were segmented using InVesalius software. A model - based on NURBS surfaces - was adjusted to the CT scans in order to obtain both smooth and natural curvatures of each model segment. All relevant tissues were modeled as separate volumes. The geometric model was discretized in order to create a numerical model for applying Ansys software (v. 15.07) and using APDL. The central incisors were loaded with external intrusive forces, ranging from 0.1 to 0.4 N. The simulation, performed iteratively, showed that even the lowest force value - 0.1 N - causes stress changes in the alveolus and on the root surfaces, with a tendency of stress increasing towards the bottom of the alveolus and root apex. It is also notable that during the application of forces of equal magnitude, the stress/strain distribution was significantly higher around tooth 21, which displayed the highest range of PDL reduction. Application of the same force level created a higher stress-strain response around tooth 21, and the characteristics were less homogenous. A force value of 0.1 N applied in vivo might produce the most effective tooth intrusion and bone modeling which favors bone defect regeneration.

A THREE-DIMENSIONAL EVALUATION OF THE EFFECTS OF DIFFERENT INCISOR INTRUSION MECHANICS TO THE PERMANENT MAXILLARY FIRST MOLAR TEETH BY USING CONE BEAM COMPUTED TOMOGRAPHY

Objective: The present study aims to evaluate the impacts of the upper incisor teeth intrusion in deepbite patients by two different techniques to the permanent maxillary first molar tooth using the three-dimensional cephalometric analysis in the individuals. Materials and Methods: The population of this study consists of 34 patients with >4 mm overbite and a ≥2 mm gummy smile during post-pubertal period. Patients who underwent intrusion of upper incisor teeth were randomized to receive Connecticut intrusion arch (CTA) or miniscrew anchorage intrusion system (MAIS) to compare the impacts on permanent maxillary first molar teeth. Cone Beam Computed Tomography (CBCT) data obtained before (T1) and after (T2) intrusion were evaluated through three-dimensional (3D) cephalometric analysis. Intragroup assessment of treatment-related variables were performed via “t-test in dependent samples” and intergroup comparisons were assessed by “t-test in independent samples”. Results: In patients who underwent intrusion of upper incisors, permanent maxillary first molar teeth became deviated distally (1.48 mm/7.63 degree) only in CTA group, a statistically significant difference was found between two groups (p<0.05). The distance between resistance centers of maxillary first molar teeth was only increased in CTA group (0.31 mm), which also statistically differed from MAIS group. Conclusion: CTA and MAIS techniques resulted in similar intrusive effects overall at the end of the treatment. While MAIS is recommended when anchorage from posterior region is not desired in patients with deep overbite, we believe that CTA may serve a suitable treatment alternative where miniscrew technique could not be performed.

Root Resorption in Mandibular Incisors During Orthodontic Treatment with Invisalign®: A Radiometric Study

Background: Existing literature indicates that orthodontics patients are more likely to have severe apical root shortening, interesting mostly maxillary, followed by mandibular incisors. Objectives: The aim of the present study was to investigate the incidence and severity of root resorption (RR) in mandibular incisors of adult patients treated with aligners. Methods: The study group consisted of 71 adult healthy patients (mean age 32.8 ± 12.7) treated with aligners (Invisalign®, Align Technologies, San Jose, CA, USA) for the intrusion of the lower incisors. Root and crown lengths of a total of 279 lower incisors were measured in panoramic radiographs at the beginning (T0) and at the end (T1) of aligner therapy. Individual root-crown-ratio (RCR) of each tooth and therefore the relative changes of RCR (rRCR) were determined. Results: 44% of the 279 measured teeth presented a reduction of the pre-treatment root length. A reduction in percentage of > 0% up to 10% was found in 26.76% (n = 76), a distinct reduction of > 10% up to 20% in 12.32% (n = 35) of the sample. 4.58% (n = 13) of the teeth were affected by a clinically relevant reduction (> 20%). Conclusions: Orthodontic treatment with Invisalign® aligners could led to RR in cases in which intrusion of the lower incisors is planned. However, the incidence of RR is comparable to data described in case of application of light forces with fixed appliances, and considerably lower than what has been described for traditional comprehensive orthodontic treatments.

Effect of orthodontic treatment on periodontal clinical attachment: a systematic review and meta-analysis.

Insertion of orthodontic fixed appliances has been known to induce a mostly transient qualitative and quantitative alteration of the intraoral microbiota. However, the extent to which treatment with fixed appliances might have a lasting adverse effect on the periodontal attachment of the teeth has not yet been investigated in an evidence-based manner. Aim of this systematic review was to assess the effect of comprehensive treatment with fixed orthodontic appliances on clinical attachment levels of adolescent and adult periodontally healthy patients. Seven databases were searched from inception to February 2017. Prospective non-randomized longitudinal clinical studies. After duplicate study selection, data extraction, and risk of bias assessment according to the Cochrane guidelines, Paule-Mandel random-effects meta-analyses of the clinical attachment loss and its 95 per cent confidence intervals (CIs) were calculated. A total of 9 trials were identified that included 335 treated patients (at least 34 per cent male / 66 per cent female) with an average age of 22.6 years. The average pooled clinical attachment loss was 0.11 mm (9 studies; 335 patients; 95 per cent CI = 0.12 mm gain to 0.34 mm loss; P = 0.338) with high heterogeneity. Furthermore, one study hinted that a small amount of clinical attachment might be gained by intrusion of upper incisors. Additional analyses indicated that the results were robust to addition of untreated patient groups, while patient age and timing of outcome measurement might play an important role. According to existing evidence from longitudinal clinical studies orthodontic treatment with fixed appliances has little to no clinically relevant effect on periodontal clinical attachment levels. PROSPERO (CRD42017057042). None.

Leveling the curve of Spee with continuous archwire appliances in different vertical skeletal patterns: A retrospective study.

The aim of this study was to determine the effects of the leveling of the curve of Spee in subjects treated with preadjusted appliances in different skeletal vertical patterns. The study sample consisted of 90 white patients (39 male, 51 female; age, 19years 4months±1year 9months), with a curve of Spee of 2mm or greater before treatment. They were categorized into 3 groups: low-angle group (30 subjects; 12 male, 18 female; age, 19years 1month±1year 4months), normal-angle group (30 subjects; 14 male, 16 female; age, 19years 6months±2years 1month), and high-angle group (30 subjects; 13 male, 17 female; age, 19years 7months±1year 5months) by their vertical facial types. Cephalometric parameters were used to evaluate the different dental movements after treatment. The curve of Spee was measured on digital dental casts. Analysis of variance was used to determine any differences between the changes in the groups with time. For the skeletal variables, no significant modifications were found in the 3 groups. For the dentoalveolar variables, the low-angle group showed significant buccal movements and intrusion of the mandibular incisors. The high-angle group had greater extrusion of the posterior teeth associated with uprighting of the first and secondmolars. In low-angle subjects, leveling of the curve of Spee occurs through buccal movement and intrusion of the mandibular incisors; in high-angle subjects, it occurs through extrusion and uprighting of the posterior teeth.

Intrusion and Lateral Luxation of Permanent Incisors in Pediatric Patient Secondary to Dental Trauma: Case Report

A comparative evaluation of bite opening by temporary anchorage devices and Connecticut intrusion arch: An in vivo study

Introduction: Deep bite correction in patients with convex profile and increased maxillary incisor visibility, and normal or increased vertical dimension necessitates the intrusion of maxillary incisors. Intrusion arches or miniscrews are commonly used for this purpose. The current study compares one of the prefabricated intrusion arches, the Connecticut intrusion arch (CIA), and the temporary anchorage devices (TADs) in their effectiveness for orthodontic intrusion. Materials and Methods: The present prospective study was done on 24 patients in the age group of 15–25 years undergoing fixed orthodontic treatment. In Group I, TADs were placed for intrusion while, in Group II, CIA was placed. Anchorage was reinforced in Group II using transpalatal arch. A paired t-test or a Wilcoxon signed-rank test was performed for the assessment of treatment changes within the groups, and an independent t-test or a Mann–Whitney U-test evaluated change between the groups. Results: Both TADs and CIA can bring about significant amount of true incisor intrusion with resultant decrease in incisor visibility. However, in the TAD group, in addition to intrusion, the incisors also proclined by 0.67 mm, but in CIA group, incisors retracted by 0.33 mm. There were nonsignificant mesial drift and significant extrusive movement of the maxillary first molars in the CIA group. The rate and amount of intrusion was greater in the TAD group. Conclusions: Both TADs and CIA can be effectively used for incisor intrusion which was, however, faster and greater in TAD group. Both the methods bring about associated unwanted tooth movements as well.

Effect of premolar extractions on facial vertical dimension- A cephalometric study

Background: The purpose of this study was to compare changes in the facial vertical dimension in patients after the extraction of maxillary and mandibular premolars. Materials and methods: The pre and post treatment records of 20 patients of age range 18-25 years who had skeletal class II with hyperdivergent facial form and have undergone maxillary and mandibular first premolar extractions for orthodontic treatment under Roth prescription were taken. Results: There was significant increase seen in the maxillo-mandibular plane (MM angle) and Steiner’s SN (Go-Gn) angle of pre and post treatment cephalometric records. Conclusion: The results of this study showed that stress should be given on incisor intrusion and extrusion of molars should be avoided to prevent further increase in vertical dimensions in vertical growers. Keywords: Vertical dimension, Premolar extractions

Orthodontic intrusion of maxillary incisors: a 3D finite element method study

Objective: In orthodontic treatment, intrusion movement of maxillary incisors is often necessary. Therefore, the objective of this investigation is to evaluate the initial distribution patterns and magnitude of compressive stress in the periodontal ligament (PDL) in a simulation of orthodontic intrusion of maxillary incisors, considering the points of force application. Methods: Anatomic 3D models reconstructed from cone-beam computed tomography scans were used to simulate maxillary incisors intrusion loading. The points of force application selected were: centered between central incisors brackets (LOAD 1); bilaterally between the brackets of central and lateral incisors (LOAD 2); bilaterally distal to the brackets of lateral incisors (LOAD 3); bilaterally 7 mm distal to the center of brackets of lateral incisors (LOAD 4). Results and Conclusions: Stress concentrated at the PDL apex region, irrespective of the point of orthodontic force application. The four load models showed distinct contour plots and compressive stress values over the midsagittal reference line. The contour plots of central and lateral incisors were not similar in the same load model. LOAD 3 resulted in more balanced compressive stress distribution.

Finite element analysis of maxillary incisor displacement during en-masse retraction according to orthodontic mini-implant position.

ObjectiveOrthodontic mini-implants (OMI) generate various horizontal and vertical force vectors and moments according to their insertion positions. This study aimed to help select ideal biomechanics during maxillary incisor retraction by varying the length in the anterior retraction hook (ARH) and OMI position.MethodsTwo extraction models were constructed to analyze the three-dimentional finite element: a first premolar extraction model (Model 1, M1) and a residual 1-mm space post-extraction model (Model 2, M2). The OMI position was set at a height of 8 mm from the arch wire between the second maxillary premolar and the first molar (low OMI traction) or at a 12-mm height in the mesial second maxillary premolar (high OMI traction). Retraction force vectors of 200 g from the ARH (-1, +1, +3, and +6 mm) at low or high OMI traction were resolved into X-, Y-, and Z-axis components.ResultsIn M1 (low and high OMI traction) and M2 (low OMI traction), the maxillary incisor tip was extruded, but the apex was intruded, and the occlusal plane was rotated clockwise. Significant intrusion and counter-clockwise rotation in the occlusal plane were observed under high OMI traction and -1 mm ARH in M2.ConclusionsThis study observed orthodontic tooth movement according to the OMI position and ARH height, and M2 under high OMI traction with short ARH showed retraction with maxillary incisor intrusion.

Rate of intrusion of maxillary incisors in Class II Div 1 malocclusion using skeletal anchorage device and Connecticut intrusion arch

BackgroundNonsurgical correction of deep bite involves either extrusion of posterior teeth, intrusion of incisors, or combination of both. The introduction of skeletal anchorage device with microimplant provides near absolute anchorage without producing any untoward effects on anchor unit. Connecticut Intrusion Arch (CIA) provided an efficient system of intruding anterior segment without producing much adverse affects on anchor teeth. MethodsThe study comprised of 30 patients of Class II Div 1 malocclusion with overbite of >6mm and required therapeutic extractions of all first premolars, randomly distributed into two groups. Group 1 was treated using orthodontic microimplants, while Group 2 treated with CIA. Lateral cephalograms were taken pre-intrusion (T1) and post-intrusion at the end of six months (T2). ResultsThe rate of intrusion was 0.51 and 0.34mm/month for Group 1 and Group 2 respectively. The average amount of change in centroid point to PP distance and U1-SN angle was significantly higher in Group 1 compared to Group 2 (P<0.001). The average amount of change in U6 to PP distance did not differ significantly between two study groups (P>0.05). ConclusionThe amount of intrusion is significantly higher in SAD group. Although vertical molar positional change was higher in CIA group than the SAD group, it was not changed significantly in both treatment modalities. SAD group overall had better results and was easier in handling during intrusion.

Comparative evaluation of intrusive effects of miniscrew, Connecticut intrusion arch, and utility intrusion arch – An in vivo study

ObjectivesThis study compared the skeletal and dental changes obtained by incisor intrusion using three methods: utility intrusion arch (UIA), Connecticut intrusion arch (CIA), and miniscrews. Materials and methodsA total of thirty-eight patients with age range of 14–25 years were included which were divided into three groups: Group I (n=13), UIA; Group II (n=13), CIA; and Group III (n=12), miniscrew. All the groups were further subdivided into maxillary and mandibular arch. Intrusion force of 60g and 40g was used for maxillary and mandibular arch respectively for standardization. Intrusion was concluded after 5–6 months or when correction was achieved. Pre-treatment and post-treatment skeletal and dental changes were compared sing lateral cephalograms. ResultsThe results suggested that all three methods were effective means of intrusion, but true intrusion measured from center of resistance was maximum in miniscrew group. No anchorage loss and change in axial inclination of incisors was observed in miniscrew group as compared to UIA and CIA group. Overbite decreased in all groups but more significantly in miniscrew group. ConclusionsMiniscrew intrusion was considered the preferred method of true intrusion to correct deep bite.

Case Report: An 8-year-old girl was referred to Gazi University Faculty of Dentistry, Department of Pediatric Dentistry, who suffered from slide accident within 1 hours. During clinical examination intrusion of maxillary right central incisor(#11), extrusion of maxillary left central incisor(#21) and anterior cross-bite were detected. While considering the multiple trauma, it was decided that repositioning of #21 and waiting for the spontaneous re-eruption of #11 that has open apices, would be the best choice. In addition, teeth were splinted with non-rigid splint. At the 6th month follow-up, loss of vitality and discoloration of #21 was determined. Apexification was indicated. The patient was followed-up for 24 months. Results: The intruded tooth was re-erupted spontaneously in 12 months. Moreover anterior cross-bite was also corrected without any intervention. Apexification of the #21 was shown no symptoms radiographically or clinically throughout the 12th, 18th and 24th month follow-ups. Conclusion: This case report features that the treatment planning of multiple trauma patients and follow-ups should be highlighted to have great importance.

Hypoplasia Management in permanent incisor caused by primary incisor intrusion- A case report

Abstract Orofacial trauma is a serious orodental and general health problem that may have medical, esthetic and psychological consequences for children and their parents. When the root of the primary tooth is close to the unerupted permanent tooth, primary tooth trauma may result in developmental disturbances and pulpal reaction in that permanent tooth. We report a case in which injury to the primary dentition resulted in developmental disturbances in the underlying permanent tooth. Localized malformation of the crown and enamel hypoplasia was treated with a light-cured composite resin restoration. How to cite this article Neena IE, Ananthraj A, Praveen P.
