Assessing position changes of impacted third molars in treatment of class II malocclusion with premolars extraction.

Third molars (M3) remaining impacted in Class II malocclusion characterised with sagittal mandibular deficiency is a high probability. The null hypothesis of this study is that mesioangular M3s changes position through the eruption way inClass II malocclusion treatmentrequiring moderate anchoragewith four first premolars extraction.The aim of this study is to reconsider the decision to surgically extract impacted third molars in four premolars extraction treatment of Class II malocclusion. The materials consisted of the pre-treatment and post-treatment lateral cephalograms and orthopantomographs of 30 individuals with skeletal and dental Class II malocclusion with a mean chronological age of 13.48 years, who were treated by the same clinician (H.G.) with four first premolar extractions via the straight wire technique at the Ankara University Faculty of Dentistry Department of Orthodontics, Ankara, Turkey. The sagittal position of the upper and lower incisors and molars, M3position and M3space were evaluated with the paired-t test; the relationship between the sagittal position of the upper and lower incisors and molars and the change in M3position were evaluated with correlation analysis. Results: The study found the retroclination and mesial movement of the upper incisors and molars, and an increase in the M3space by the fixed orthodontictreatment. An insignificant steepening of both the upper right M3position and the lower right M3position was found. A statistically significant increase in the lower right and left side M3spaces was found. Positive correlations between lower right M3angulation and the sagittal position of the lower incisors and first molars were found. Improvement in the mesioangulation of the M3s and an increase in the M3space were achieved in this study. Based on the findings, it is useful to review the decision for prophylactic surgical extraction of the M3s before orthodontic treatment in such cases, taking into account the risks of postoperative complications.

Digital setup accuracy for moderate crowding correction with fixed orthodontic appliances: a prospective study

ObjectivesTo evaluate the accuracy of a semi-automatic 3D digital setup process in predicting the orthodontic treatment outcome achieved by labial fixed appliances.Subjects and MethodsTwenty-five adult patients (18 to 24 years old) with class I malocclusion and moderate crowding were prospectively enrolled and received treatment on both jaws through the straight-wire technique. Prior to treatment commencement, a semi-automatic digital setup simulating the predicted treatment outcome was performed for each patient through Orthoanalyzer software (3Shape®, Copenhagen, Denmark) to obtain the prediction model. This was compared to the final outcome model through 3D superimposition methods. Metric variables and inspection of color-coded distance maps were used to detect how accurately the digital setup predicts the actual treatment outcome.ResultsThe mean absolute distances (MAD) between the superimposed dental arches of the predicted and the final models were: 0.77 ± 0.13 mm following superimposition on the palate, 0.52 ± 0.06 mm following superimposition on the maxillary dental arch, and 0.55 ± 0.15 mm following superimposition on the mandibular dental arch. The MAD at the palatal reference area was 0.09 ± 0.04 mm. Visualization of color-coded distance maps indicated that the digital setup accurately predicted the final teeth position in a few cases. Almost half of the cases had posteriorly wider upper and lower dental arches and palatally/lingually positioned or inclined anterior teeth, whereas the rest still showed errors within 2–3 mm, distributed over the entire dental arches with no distinct pattern.ConclusionsThe accuracy of semi-automatic prediction of the labial fixed appliance treatment outcome in Class I cases with moderate crowding is not yet sufficient. While average measures showed deviations less than 1 mm, examination of individual color-coded distance maps revealed significant disparities between the simulated and the actual results.

A patient with bimaxillary protrusion was treated by the extraction of four premolars and four compromised first molars: a case report

Abstract The first molar has been reported to be the most caries prone tooth in the permanent dentition. Rarely is the extraction of the four first molars the ideal choice in orthodontic treatment, especially the extraction of four molars and four premolars. However, the extraction program presents a treatment alternative in selected cases. In the following case report, the orthodontic treatment is described a 15-year-old male patient who presented with a dentoskeletal bimaxillary protrusion, and a chief complaint of”crooked teeth”. Moreover, the patient had a skeletal Class I malocclusion with crowded dentitions, a hyperdivergent growth pattern, deviated midlines and an extremely deep Curve of Spee. A satisfactory treatment outcome was obtained by the extraction of four premolars and four compromised first molars. The mechanics involved alignment, levelling, detailing the occlusion using a straight arch wire technique followed by retention. The active treatment time was 48 months. The treatment successfully achieved a bilateral Class I relationship of the canines and the right molars, a mild Class III relationship of the left molars, a normal overjet and overbite, aligned dental midlines, optimal intercuspation and a harmonious facial profile. The occlusion remained stable during 5 years of review.

Technical specification for orthodontic transmission straight wire technique

Malocclusion is an oral disease with a high prevalence. The goal of orthodontic treatment is health, aesthetics, function and stability. The transmission straight wire appliance and technique is an innovative orthodontic system with independent intellectual property rights invented by Professor Jiuxiang Lin's team based on decades of clinical experience, which provides a new solution for the non-surgical correction of skeletal malocclusions, especially class Ⅲ malocclusion, and it is also a good carrier for the implementation of the concept of healthy orthodontics. Due to the lack of guidelines, how to implement standardized application of transmission straight wire technique remains a problem to be solved. This technical specification was formed by combining the guidance from Professor Jiuxiang Lin and joint revision by a number of authoritative experts from the Orthodontic Special Committee, Chinese Stomatological Association, with reference to relevant literatures, and combined with abundant clinical experience of many experts. This specification aims to provide reference to standardize the clinical application of transmission straight wire technique, so as to reduce the risk and complications, and finally to improve the clinical application level of this technique.

Case report: A-short period management of female adolescent with Papilary Penetrating (PP) frenulum attachment

Background: A space between the anterior teeth and midline diastema is really important for aesthetic concerns in adolescents. Midline diastema may be related to high frenal attachment. Frenectomy is a treatment option for high frenal attachment. The entire removal of the frenum may be followed by orthodontic treatment. Case Presentation: A female 16-year-old patient complained of feeling embarrassed because of a gap in her front teeth. A frenectomy with orthodontic treatment is used to correct midline diastema. A frenectomy procedure uses conventional technique. The Straight Wire Technique (SWT) technique for orthodontic treatment. Midline diastema is complete correction at the 3rd control. Conclusion: Frenectomy before orthodontic treatment, followed by a medium-anchored Straight Wire Technique (SWT) with an elastromic chain or power chain, can be an alternative technique with a short duration.

The use of straightwire technique and myofunctional therapy to treat anterior open bite due to tongue thrusting (case report)

Background : In contrast to the posterior teeth, which are still in occlusion, No incisal contact in the anterior part of the maxilla and mandibula between the vertical dimension is referred to as anterior open. Skeletal irregularity during the expansion of the intermaxillary gap and poor habits can both contribute to openbite. Tongue thrusting is one of the undesirable practices that might result in anterior openbite. Objective : This treatment's objective is to break negative habits by employing myofunctional therapy to develop a healthy swallowing pattern and train the posture of the tongue and lips while at rest. Case Report : A 19-year-old woman who protruded her tongue visited a dental office with the main complaint of an unattractive anterior open bite. She had an open bite of 12 12 21 22 dan 31 32 41 42, a Class II Division I subdivision Angle, a Class II skeletal relationship (protruding maxilla, retrusive mandibula, and bidental protrusive), an overjet of 6.87 mm, an overbite of 0.43 mm, and a Class II skeletal relationship. Case Management : myofunctional therapy combined with straightwire orthodontic treatment. Result : The anterior open bite is rectified, the overjet is reduced to 2,2 mm, and the overbite is increased to 2 mm after 16 months of therapy. The patient's poor swallowing pattern has improved, and their terrible tongue-trusting behavior has decreased. Conclusion : Straightwire method and myofunctional therapy are both effective treatments for anterior openbite repair brought on by tongue thrusting.

Eighteen-Month Orthodontic Bracket Survival Rate with the Conventional Bonding Technique versus RMGIC and V-Prep: A Split-Mouth RCT

The association of the V-prep and a resin-modified glass ionomer cement (RMGIC) has shown to be a suitable alternative for the orthodontic bracket bonding procedure in vitro. The aim of this study was to evaluate over eighteen months the clinical bonding failure and survival rates of the conventional bonding technique using the Transbond XT (3M Unitek, Monrovia, CA, USA) and the RMGIC Fuji Ortho LC (GC Corporation, Tokyo, Japan) prepared with the V-prep. Therefore, one operator using the straight-wire technique bonded two hundred metallic brackets to upper and lower premolars of twenty-five patients requiring an orthodontic treatment. The randomized trial was a single-blind design in a split-mouth comparison. Each patient was randomly allocated one of the two bonding systems for each premolar on each side of the mouth. The bonding and rebonding techniques were standardized throughout the trial and bond failure was recorded each month for a period of eighteen months. The survival rates of the brackets were estimated by Kaplan–Meier and log-rank test (p < 0.05). A total of 200 orthodontic brackets were included in the study with a significant lower failure rate of 9.0% for the V-prep and RMGIC compared to 25.0% for the conventional bonding technique (p < 0.05). A higher survival rate was observed for the V-prep and RMGIC (16.36 months) over the conventional bonding technique (13.95 months) (p < 0.05). Lower premolar bonding failure was higher than upper premolar for both bonding techniques. The V-prep followed by RMGIC, with enamel surface protection abilities, can be used as an alternative bonding technique in an orthodontic treatment.

Accuracy of planned tooth movement with lingual straight wire technique.

To analyze the accuracy of planned tooth movements of torque, tip, rotations, and transverse width values with lingual straight-wire technique. 40 Caucasian subjects with mean age of 23.9 years, consecutively treated in private practice with a lingual straight-wire appliance (STb, Ormco, Glendora, Calif) were evaluated. Maxillary and mandibular dental casts were taken before treatment (T0), in the setup (T1), and at the end of treatment (T2) and scanned with an intraoral 3D scanner Carestream CS 3600 (Carestream Dental, Atlanta, GA). Virtual models at the three time points were superimposed on T1 using 3D software, and the coordinates were exported as a set of x, y, and z values. Angular and linear measurements were analyzed to measure torque, tip, rotation movements, and transverse intra-arch widths. Changes among the three time points were analyzed with Friedman's nonparametric test. A general increase in torque was recorded in the setup and in the final result, except for the maxillary molars. Torque, tip, and rotation movement mean accuracy was ≥84% for incisors, canines, and premolars. A general increase in transverse width was measured in the setup and in the final models, except for the upper second molars, which showed reduced transverse width during treatment. The movements planned in the setup to obtain the ideal torque, tip, and rotations actually occurred, except for second molars, which showed less accuracy. Planned expansion of the arches occurred only partially.

Straight wire and segmented technique in canine retraction-case reports

Correct positioning of the canines after their retraction is of great importance for the function, stability and esthetics. Aim: Two case reports were presented to compare the efficiency of two techniques for canine retraction, segmented mechanics using 0.017 x 0.025 TMA T-loop vs sliding straight-wire mechanics usingelastomeric chains. Material and methods: The first case describes orthodontic treatment with 0.017 x 0.025 TMA T-loop whereas the second case describes a 9 mm canine retraction using elastomeric chains. Results: Depending on the type of malocclusion both techniques for canine retraction can be used. Post treatment results showed canine retraction with good anchorage control and no mesial movement of the molars.Conclusion: Both techniques provide an optimum rate of tooth movement and none of the methods can be considered superior in terms of tooth movement or side effects, including rotation, tipping, root resorption, anchorage loss, as well as associated pain.

A new device for measuring orthodontic compressive bonding force; a novel bracket positioning gauge with a force sensor

Objectives: The optimum adhesive thickness present between bracket base and tooth surface plays an important role in achieving ideal treatment outcome in straight wire technique. As thickness of adhesive largely depends on amount of force applied while bonding an orthodontic brackets on the tooth surface. Therefore, it becomes prudent to find direct and accurate method to quantify the bonding force. The aim of this paper was to describe the design and working of novel bracket positioning gauge with force sensor which directly quantifies the amount of bonding force applied by orthodontists. Material and Methods: The present prototype is a bracket positioning gauge where load cell and vertical stopper blade are fixed on base platform. The force sensing blade attached to load cell detects the force applied and transmit to load cell which converts compressive force into an analogue signals. These inputs are then converted into digital signals for further processing. The prototype was tested five times by ten orthodontists for measuring bonding force while orthodontic brackets were bonded on extracted premolars. The same procedure was repeated after seven days to assess the reproducibility and reliability of prototype. Results: The majority of orthodontists participated in present study applied bonding force between the ranges of 50-200 grams with the mean bonding force applied by participant orthodontists was similar in time interval of seven days with 134.67 grams and 132.76 grams respectively. Conclusion: The novel bracket positioning gauge with force sensor was able to measure compressive bonding force accurately and can aid in achieving optimum adhesive thickness for clinically acceptable bond strength. The present innovation needs further refinements to be more useful in clinical settings.

Management of Impacted Permanent Canine on Upper Jaw with Surgical Exposure: A Case Report

Background: An impacted tooth is often left unidentified due to the lack of symptoms. It is generally found when the patient is examined by a dentist. The maxillary canine should be retained for strength masticatory functions, esthetics and child development.
 Purpose: To report the treatment options of impacted canine in a 12-year-old girl.
 Case Report: A 12-year-old girl presented to Kertosono General Hospital with the complaint that her upper left permanent canine had not erupted and had no history of pain. Panoramic radiograph showed the impacted position of vertical tooth 23. The shift sketch technique radiograph indicated the impacted canine located at the buccal site. Surgical exposure to the upper left maxillary canine was performed, followed by orthodontic treatment to direct tooth position into an occlusal line. A fixed orthodontic appliance used, which was a roth bracket with a straight wire technique. After surgery and orthodontic treatment, tooth 23 was in normal occlusion.
 Conclusion: Surgical exposure followed by orthodontic treatment can be performed successfully with special consideration to the patient’s age, dental space, location of dental crowns, dental inclination, apical root form of the impacted tooth and patient cooperation.

Adjunctive orthodontic management of a missing upper right central incisor in a 12-year-old male using a fixed orthodontic appliance

This article presents a successful orthodontic management of a 12-year-old male using a fixed orthodontic appliance (straight wire technique). His orthodontic treatment was hinged on creating enough space to accept an artificial tooth, correcting the horizontal and vertical relationships of the upper incisors to the lower and the midline shift. Ultimately, an esthetic smile was achieved; function and self-esteem were improved when the artificial tooth was finally fixed.

Prevalence of TMD among Children Provided with Fixed Orthodontic Treatment.

BackgroundAccording to available scientific references and textbooks, there are contradictory views concerning the etiology of signs and symptoms of TMD.ObjectivesThe aim of this study was to determine a correlation between the incidence of signs and symptoms of TMD in children aged 12-18 who do not wear a fixed orthodontic appliance and the incidence of signs and symptoms of TMD in children who wear a fixed orthodontic appliance.Material and MethodsThe total number of 120 subjects were included in this survey and divided into two groups. There were 60 respondents in the experimental group that consisted of 30 boys and 30 girls with different types of malocclusion, who were treated with a fixed orthodontic straight wire technique. The remaining 60 respondents, which was a group that also consisted of 30 boys and 30 girls, were patients with neutroclusion.ResultsThe results of the study have shown that the TMJ clicking sound symptom, the most common symptom of TMD, occurs with almost equal prevalence in both groups of respondents; specifically, 56.4% in orthodontic patients, and 46.6% in the control group respondents. A statistically significantly higher percentage of female respondents in both groups have experienced headache problems (p <0.03).ConclusionOn the basis of the statistics obtained as a result of this research, we can come to the conclusion that there is no correlation between the fixed orthodontic treatment and the development of signs and symptoms of TMD.

The difference between Begg and Straightwire appliances on molar position, occlusal plane angle, and anterior and posterior facial height changes

Background: Bimaxillary and bidental protrusion Class I Angle malocclusions have a characteristic convex facial profile and protrusion lips due to the labial inclination of the anterior teeth. Extraction of the first four premolars is the most common choice for orthodontic treatment of these cases when all the permanent teeth are complete and in good condition. Orthodontic treatment can be performed using the Begg or Straightwire techniques. Purpose: This study aims to investigate the difference in the effect of orthodontic treatment with Begg and Straightwire appliances on molar position, occlusal plane, and anterior and posterior facial height. Methods: Sixty pairs of lateral cephalograms before and after the treatment of patients with bimaxillary and bidental protrusive Angle malocclusion Class I, aged 18–35 years old, who underwent orthodontic treatment using the Begg and Straightwire techniques with the extraction of all first premolars that met the inclusion criteria. Data analysis was performed using two-way repeated analysis of variance (p&lt;0.05) and Pearson correlation (p&lt;0.05). Results: Molar position, occlusal plane angle, and anterior and posterior facial heights increased significantly after the Begg technique treatment and decreased significantly after the Straightwire technique treatment (p&lt;0.05), but there were no significant differences between the four variables in the two techniques (p&gt;0.05). Medium correlation was found between variables in both the Begg and Straightwire techniques. Conclusion: Molars were extruded and mesialized and the occlusal plane angle and height of the anterior and posterior faces increased after the Begg appliances treatment. The molars moved mesially and occlusally and there was a decrease in the occlusal plane angle, as well as the height of the anterior and posterior faces, after treatment with the Straightwire appliances. However, there was no difference between the two techniques.

The effect of fixed orthodontic treatment with Edgewise and Straightwire techniques on white spot lesions incidence and accumulation of Streptococcus mutans bacteria

Background: Fixed orthodontic appliances, such as Edgewise and Straightwire techniques, can increase the amount of plaque retention containing Streptococcus mutans (S. mutans), which can lead to white spot lesions. Purpose: The aim of this study is to analyse the correlation of fixed orthodontic treatment with Edgewise and Straightwire techniques on the incidence of white spot lesions and accumulation of S. mutans. Methods: The samples consisted of three groups: control group (n=8), Edgewise technique group, and Straightwire technique group. We observed the samples at the sixth month and eighth month of the treatment, after the installation of the fixed orthodontic appliances. The observation of white spot lesions with caries detector was applied in all regions. Bacterial swabs were acquired in the lateral incisor region, then a bacterial culture procedure was carried out on selective media of S. mutans, and then a bacterial count was performed. The data was analysed using two-way ANOVA, the post-hoc least square differences test, and the Pearson’s correlation test. Results: The number of white spot lesions in the Edgewise group was higher than in the Straightwire group in the sixth and eighth month of treatment with insignificant difference (p&gt;0.05). The number of S. mutans bacteria increased in all groups, but there were no significant differences (p&gt;0.05). There was no significant relationship between the number of white spot lesions with the accumulation of S. mutans between groups (p&gt;0.05). Conclusion: The Edgewise and Straightwire techniques increase the incidence of white spot lesions but accumulation of S. mutans with the incidence of white spot lesions has no relationship.

Therapeutic effect analysis of skeletal class Ⅲ malocclusion treatment by transmission straight wire technique

This study aimed to investigate the therapeutic effects and advantages of skeletal class Ⅲ malocclusion treatment by transmission straight wire technique. Ninety-seven patients who receivedtreatmentfor skeletal class Ⅲ malocclusion atthe Department of Stomatology, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2012 to January 2017 were selected for this retrospective study. All these patients refused surgery. They were divided into two groups in accordance with the type of skeletal malocclusion: mild-to-moderate skeletal malocclusion group (-4°≤ANB <0°) and severe skeletal malocclusion group (-8°≤ANB<-4°). Each of the two groups was divided further into two small groups in accordance with the technique used: T group (transmission straight wire technique) and M group (MBT technique). The crossbite of all 59 patients in the mild-to-moderate skeletal malocclusion group was successfully treated. The molars were classified as classⅠrelationship, and the facial profile improved. Significant differences were found in the values of U1/SN angle, L1/MP angle, and Lip-Diff between the T and M groups before and after the treatment (P<0.05). The extent of incisor root resorption was lighter in the T group than in the M group (P<0.05). In the severe skeletal malocclusion group, the crossbite of all 38 patients was cured or partially cured. Fourteen patients showed severe lower anterior teethinclination (five in the T group and nine in the M group), and the profiles did not significantly improve. Significant differences were observed in the values of U1-NA value, U1/SN angle, L1-NB value, L1/MP angle, LLP, and Lip-Diff between the T and M groups before and after the treatment (P<0.05). The extent of incisor root resorption was lighter in the T group than in the M group (P<0.05). Relative to the MBT technique, the transmission straight wire technique has great advantages in improving facial profile, reducing the compensatory inclination of the upper and lower anterior teeth, and reducing the risk of root resorption in the treatment of skeletal class Ⅲ malocclusion.

Analysis of tooth anatomy in adults with ideal occlusion: A preliminary study

The aim of this study was to investigate the vestibular anatomy of teeth in samples of adult Italian and Mozambican subjects in ideal occlusion and permanent dentition and identify any anatomic characteristics that may influence bonding in the straight-wire technique. Linear measurements and coordinates of each curve representing the clinical crown height and width of each tooth were acquired from digital models of each subject categorized to 1 of 2 groups: Italian (18 males, 22 females; mean age, 29.6±5.7years) or Mozambican (14 males, 15 females; mean age, 23.4±5.9years). All subjects had normal dentition and no previous orthodontic treatment, fillings, or prostheses. Method error and systematic error were calculated according to the Dahlberg formula (S2=∑ d2/2n) and dependent Student t test (P<0.05), respectively. Tooth symmetry was investigated through a paired-samples t test (P<0.05) and sex difference via an independent-samples ttest (P<0.05). After neither asymmetry nor sexual dimorphism was found, all data were pooled, inverting the signs of the X coordinates and then mirroring data. Subsequently, a 2-samples t test (P<0.05) and a multivariate cluster analysis were performed on the mirrored data to compare the 2 groups and to identify any within-group diversity for number of clusters for each tooth. Means of all linear measurements and coordinates (crown height and width) calculated for each cluster were reported and compared using a standard 2-samples t test (P<0.05). Two clusters were identified for the maxillary second premolars and molars in Italian subjects, whereas in the Mozambican subjects, there were 2 clusters for the maxillary first premolars and lateral incisors and 3 clusters for the maxillary canines and central incisors. The mandibular arch was remarkably homogeneous, with only 1 cluster per tooth in each group. In the mandibular arch, statistical differences were recorded between ethnic groups in crown height at the central incisors and secondmolars and in crown width in the sector from the second premolar to the secondmolar. There were considerable differences both between and within racial groups in crown height, crown width, and numbers of clusters, which should be taken into account during bonding. Although single-bracket placement guides specific for ethnicity may be feasible for the mandibular arch, the significant diversity in number of clusters in the maxillary arch indicates that more accurate bracket placement guides that take into account such heterogeneity are required.

Orthodontic Camouflage Treatment of a High-Angle Severe Skeletal Class II Discrepancy Skeletal Cla

Proper orthodontic treatment in adult patients with severe skeletal Class II discrepancy can be challenging. Recently, miniscrew implants have been used as a strategy to treat skeletal Class II patients. Objective: This report illustrates a skeletal Class II malocclusion management combining straight wire technique and miniscrew implant anchorage. Case report: The patient was a 21-years- old Indonesian female with Class II skeletal discrepancy, a retrognathic mandible, a high mandibular plane angle, and a mouth breathing habit due to a history of allergic rhinitis. Anchorage control is important in the sagittal and vertical directions. Miniscrew implants were placed in the interradicular ar ea bet ween t he upper second pr emolar and fir st mol ar on bot h sides. Further more, en -masse retraction of the six anterior teeth was performed using miniscrew implants as the anchorage. After 16 months of treatment, esthetics and function were improved and the chief complaint of the patient was resolved. Class I canine and incisor relationship was achieved. These mechanics contributed to the correction of the gummy smile of this patient. Conclusion: Placement of miniscrew implants in the posterior regions of the maxilla effectively camouflaged a high-angle skeletal Class II discrepancy. This technique requires minimal patient compliance and is useful for the correction of high-angle cases in adult patients.

Osseointegrated implant as an auxiliary of orthodontic leveling in case of asymmetric vertical skeletal discrepancy – case report

The aim of this work is to present a case report where an osteointegrated implant was used as skeletal anchorage unit in association with fixed orthodontic appliance in the treatment of an adult patient with vertical asymmetrical skeletal discrepancy. In this case report, the pre-existing osseointegrated implant in the region of element 21 was used as an aid of skeletal anchorage for the leveling of the upper occlusal plane by means of the straight-wire technique, Capelozza standard I slot .022 ", using the sequence of arches of nickel-titanium thermo-activated .014 ", .016", .017 "X.025" and .019X.025 ", followed by the steel arch .019" X.025". The results presented in this report demonstrated the osteointegrated implant as a good option, when used as anchorage resource to help orthodontics, providing better conditions of comfort and esthetics, as well as simplifying the technique.
