Comparison of Intrusive Effects and Amount of Root Resorption in Maxillary Incisors Using Two Conventional Intrusion Arches and Mini-Implants

ABSTRACT Aim and Objective: This study aimed to compare the amount of maxillary incisor intrusion and root resorption using three methods: mini-implants, utility arches, and Connecticut intrusion arches. Materials and Methods: Eighteen patients aged 15 to 25 years with deep bite were divided into three groups: 10 patients each for mini-implant, utility arch, and Connecticut intrusion arch groups. Bilateral mini-implants were used in Group 1, while utility and Connecticut arches were used in Groups 2 and 3, respectively. Intrusion was performed over four months. Lateral cephalograms and orthopantomograms were taken at the start (T1) and after four months (T2). Results: The mean incisor intrusion measured by U1-PP was 2.08 mm in Group 1, 1.55 mm in Group 2, and 1.75 mm in Group 3 (P < 0.05). CR-PP measurements showed 1.91 mm in Group 1, 1.56 mm in Group 2, and 1.66 mm in Group 3 (P < 0.05). Incisors in Group 1 showed minimal protrusion compared to significant protrusion in Groups 2 and 3 (P < 0.05). Maxillary molars showed no significant changes in Group 1 but distal tipping in Groups 2 and 3 (P < 0.05). No root resorption was observed in any group. Conclusion: Mini-screws demonstrated the most effective maxillary incisor intrusion with minimal side effects compared to utility and Connecticut intrusion arches.

Evaluation of dentoalveolar changes following maxillary incisor intrusion with one vs two anterior miniscrews in subjects with gummy smile: a randomized clinical trial.

To examine dentoalveolar changes following intrusion of maxillary incisors with one or two anterior miniscrews in subjects with gummy smile and deep bite. Forty-three subjects were selected and divided into two groups: group I (22 subjects: 15 women, 7 men; mean age 30 ± 10 years) received one miniscrew between the upper central incisors, and group II (21 subjects: 16 women, 5 men; mean age 30 ± 10 years) received two miniscrews between the canines and lateral incisors. Dentoalveolar parameters, including amount of intrusion, root resorption, incisor inclination, alveolar bone thickness, and buccal alveolar crest height (cementoenamel junction to labial alveolar crest), were evaluated using cone-beam computed tomography scans obtained before and after intrusion. The intergroup comparison was analyzed using a paired t-test and unpaired t-test to determine significant changes within and between groups. The amount of intrusion was significantly greater in group II than in group I (P < .05). No statistically significant differences were found between groups I and II for changes in incisor inclination, labial bone thickness, and buccal alveolar crest height (P > .05). Maxillary central and lateral incisor intrusion was significantly greater in subjects treated with two miniscrews. Root resorption of the maxillary central incisors was notably greater in subjects with one miniscrew, while maxillary lateral incisor resorption was greater in subjects treated with two miniscrews.

Biomechanical analysis of miniscrew-assisted molar distalization with clear aligners: a three-dimensional finite element study.

To compare the biomechanical characteristics of maxillary molar distalization with clear aligners in conjunction with three types of miniscrew anchorage. Three-dimensional (3D) finite element models of maxillary molar distalization with clear aligners and three types of miniscrew anchorage were established, including (A) control group, (B) direct buccal miniscrew anchorage group, (C) direct palatal miniscrew anchorage group, and (D) indirect buccal miniscrew anchorage group. The 3D displacement of maxillary teeth and the principal stress (maximum tensile and compressive stress) on the root and periodontal ligament (PDL) during molar distalization were recorded. The tooth displacement pattern during maxillary molar distalization in the four groups showed similarities, including labial tipping of anterior teeth, mesial and buccal tipping of premolars, and distal and buccal tipping of molars, but with varying magnitudes. Group C exhibited the greatest molar distalization, with the first molar achieving 0.1334 mm of crown distalization. Group D demonstrated a notable buccal crown movement (0.0682 mm) and intrusion (0.0316 mm) of the first premolar. Compared to Groups A and B, Groups C and D showed less labial crown tipping of the central incisor. Group B showed the greatest amount of maxillary incisor intrusion (central incisor: 0.0145 mm, lateral incisor: 0.0094 mm). Moreover, Groups C and D displayed significantly lower levels of compressive and tensile stress in the roots and PDL of the maxillary central and lateral incisors. Molar distalization is a dynamic process involving sequential tooth movement stages; however, our research primarily examined the tooth movement patterns in the initial aligner. The use of miniscrew anchorage, especially direct palatal miniscrew anchorage, may enhance the treatment efficacy of maxillary molar distalization with clear aligners, leading to increased molar distalization, reduced mesial movement of premolars, and minimized labial tipping of anterior teeth.

Management of Concomitant Intrusion and Complicated Crown-Root Fracture Injury of Maxillary Central Incisors in a Child

Dental intrusions are a severe type of injury because they impact the neurovascular supply of the tooth as well as the supporting tissues which predispose the tooth to necrosis and root resorption. Management of these injuries requires repositioning of the teeth under close monitoring to avoid complications. The management becomes more comprehensive when an intrusion is combined with other injuries, such as a crown-root fracture. This case report represents a 4-year follow-up of a child who suffered from a concomitant injury of intrusion and complicated crown-root fracture to the maxillary immature permanent central incisors. The management involved a multidisciplinary approach including endodontics, pedodontics, orthodontics, periodontics, and prosthodontics. Given the guidelines of dental trauma and the circumstances of the case, the fractured teeth were root canal treated, filled with a bioceramic plug and gutta-percha, and then restored with posts/cores and temporary crowns. The intrusion was managed initially by passive eruption followed by an active orthodontic eruption, after which the teeth were restored with permanent ceramic crowns. Throughout the course of treatment, the teeth showed no complications of root resorption or ankylosis, although one tooth developed a periapical infection which was managed by apical surgery. At the 4-year follow-up, the teeth revealed healthy periodontium and good esthetics.

Alveolar bone changes around maxillary incisors after intrusion and retraction with controlled tipping versus bodily movement : Aretrospective cone-beam computed tomography study.

To compare the effect of maxillary incisor intrusion and retraction with controlled tipping (CT) versus bodily movement (BM) in extraction cases on alveolar bone height and thickness, using cone-beam computed tomography (CBCT). Correlations between changes in alveolar dimensions and crown or root retraction, incisor inclination, and intrusion were also investigated. In all, 144 incisors of 36 women were retrospectively evaluated. All patients were treated with anterior intrusion and retraction with either controlled tipping (CT) (group1) or bodily movement (BM) (group2). CBCT scans were taken before and after retraction and intrusion and measurements of alveolar bone height and thickness at the level of mid-root and root apex were measured. The prevalence of dehiscence was also calculated. Labial bone thickness (BT) increased at the level of the root apex with increased total BT in the CT group (p < 0.05). The BM group showed decreased palatal BT. Significant vertical bone loss with an increased incidence of dehiscences occurred on the palatal side in both groups. Changes in palatal bone area was negatively correlated with the amount of root apex retraction, while the total BT at the level of root apex was positively correlated with amount of intrusion. Bodily retraction can result in reduced palatal bone dimensions and an increase risk of iatrogenic sequelae following anterior retraction in extraction cases. Vertical bone loss and an increased incidence of dehiscences is to be expected following anterior retraction. Careful attention must be paid to the bone boundary conditions to avoid moving the incisors out of the alveolar housing.

Surgical Repositioning Following a Severe Traumatic Intrusion of Maxillary Permanent Incisors: A Case Report

: Intrusion is the most severe luxation injury, resulting in soft and hard tissue damage. Treatment depends on the root development stage and tooth intrusion degree. Lateral luxation describes tooth displacement in any direction other than axial. The prognosis of luxated teeth depends on the emergency treatment and elapsed time. This paper reports an 11-year-old boy who sustained displacement of central and lateral incisors into the nasal cavity, and his left canine had lateral luxation. Surgical repositioning was undertaken for intruded teeth, and a splint was placed. The canine could not be repositioned due to the delay, but its position improved toward the force of the cheek after several sessions. This study contains the data obtained from a one-year follow-up.

A three dimensional finite element analysis of apical stress distribution during intrusion of maxillary central incisor with different inclinations in labial and lingual appliance systems

The objective of this study was to evaluate apical stress distribution during intrusion of the maxillary central incisor with different inclinations in the labial and lingual appliance systems using a three-dimensional finite element model.The three-dimensional finite element models of the maxillary central incisor were produced with 25 ° (normoclined), 30 ° (proclined), and 20 °(retroclined) inclinations. Each incisor model was subjected to an intrusive force of 15cN. The stress level at the apex was calculated in terms of maximum principal stresses.The stress distribution at the apex and cervix was lower in the labial compared to the lingual appliance system for the maxillary central incisor models with an inclination of 25° (normoclined) and 30° (proclined). Whereas the maxillary central incisor model with 20° (retroclined) inclination in the lingual appliance system showed the maximum stress in the cervical region.During intrusion, no significant differences in stress patterns were seen at the root apex in normoclined and proclined maxillary central incisor models in either of the appliance systems, except for the retroclined central incisor model which showed maximum stresses in the cervical region.

Comparative cone-beam computed tomographic evaluation of maxillary incisor intrusion and associated root resorption: Intrusion arch vs mini-implants

Various literature has verified that apical root resorption is a common adverse effect of orthodontic treatment, particularly intrusion. Conventional radiographic techniques underestimated root lengths and overestimated tooth lengths. Cone-beam computed tomography (CBCT) is a useful diagnostic tool to detect orthodontically induced external apical root resorption. This prospective study aimed to compare maxillary incisor intrusion and associated root resorption via CBCT. Thirty patients aged 16-23 years, having a deepbite of 6-8 mm and excessive gingival display on smiling, were divided into 2 groups: group 1, with 15 patients who were treated with Burstone intrusion arch, and group 2 with 15 patients who were treated with mini-implants applying 100 g of intrusive force for 4 months with activation done every 4 weeks. During this 4-month study period, no treatment was performed other than the intrusion of incisors. CBCT scans were obtained before and after the intrusion phase of treatment to compare the amount of intrusion and associated root resorption among both groups. No significant difference was found in mean incisor intrusion between groups 1 and 2 (P= 0.772), with slightly more proclination of incisors in group 1, resulting in a significant (P= 0.018) increase in the vertical change of incisal edge in group 1. A statistically significant difference was found in root resorption among both groups (P= 0.004), with more root resorption in group2. The results of this study indicate intrusion with both the intrusion systems using appropriate intrusive forces is effective in opening the bite with slightly more external apical root resorption in the mini-implant group.

Alveolar Bone After Intrusion and Retraction of Anterior Teeth: Fractional Dimensional Analysis

Objective: To evaluate changes in the trabecular structure of alveolar bone in maxillary incisors segment after maxillary incisor intrusion and retraction with fixed orthodontic treatment in adult patients using fractal dimensional analysis (FD). Methods: This study was conducted using a digital panoramic radiograph of 30 patients (Age Group 18 - 25 years) with class II malocclusion with maxillary incisor protrusion treated with intrusion and retraction of anterior teeth. Panoramic radiographs were taken with standard protocols at the three different periods, before orthodontic treatment (T0), immediately after alignment but before intrusion and retraction (T1), and after intrusion & retraction of anterior teeth (T2). Regions of interest were located between the apices of maxillary incisors. Findings: Fractal dimension (FD) was calculated using ImageJ software. Repeated Measure ANOVA test; indicates significant difference at p0.05. FD values of the alveolar bone of maxillary incisors at T0 were 1.312  0.09, which reduced to 1.273  0.10 at T1 and again increased to 1.325  0.07 at T2. This overall change in FD values was significant (p=0.050. Novelty: The study revealed that, during orthodontic tooth movement, the alveolar bone around the teeth was reduced. However, after a period of bone recovery, the reduced bone density recovered to its previous state from before the orthodontic treatment.

Comparing the Effect of Miniscrew-Supported and Conventional Maxillary Incisor Intrusion on the Inclination of Maxillary Incisors and Molars - A Systematic Review and Meta-Analysis.

The objective of this study was to compare the effect of miniscrew-supported maxillary incisor intrusion and conventional intrusion mechanics on maxillary incisors and molar inclination. Search databases (PubMed, Scopus, Web of Science, Embase, EBSCOhost, and the Cochrane Library) were searched for randomized trials on intrusion of maxillary incisors via miniscrew-supported and conventional mechanics. The revised Cochrane risk-of-bias tool for randomized trials (RoB 2.0) was used. Five outcomes ([i] inclination change of upper incisors, [ii] inclination change of upper molars, [iii] intrusion of incisors, [iv] vertical change in upper first molars, and [v] overbite correction achieved) were statistically pooled using Review Manager 5.3. Subgroup analysis was conducted to receive sturdiness in meta-analysis. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation. Out of 1777 studies, 7 were finally subjected to quality assessment, and 6 were included in the meta-analysis. The incisor inclination following maxillary incisor intrusion increased in miniscrew-supported intrusion in comparison to Connecticut intrusion arch (CTA) subgroup with standard mean difference of 0.66 mm (95% confidence interval = 0.16, 1.03, I2 = 0%). All the included studies showed an increase in molar inclination (distal tipping) in the CTA subgroup compared to the micro-implant group. Of all the seven included studies, only one study was identified with some concerns for the risk of bias, and the other six were judged to have an overall high risk of bias. The incisal proclination during deep-bite correction by miniscrew-supported incisal intrusion is more than that in the CTA subgroup; however, the difference may not be clinically very relevant. There is a very low quality of evidence in favor of miniscrew-supported intrusion as compared to conventional intrusion, necessitating the need for good-quality trials.

Efficiency of different miniscrew positions for maxillary incisor intrusion: A comparative cone beam study

Aim: To evaluate the treatment efficacy of two different position of mini-implant-assisted methods to intrude the maxillary incisors using cone-beam computed tomography (CBCT). Patients and Methods: The study included 26 patients with elongated maxillary incisors and a deep bite, ranging in age from 12 to 18 years. One group received anterior mini-implants, whereas the other received posterior ones at random. The AMG used elastic chains to apply about 40 g of force per side, while the PMG used beta-titanium wires. This investigation used CBCT scans that were performed before and after an intrusion that lasted 18 weeks. Result: Significant changes in the labial inclination of all incisors, which were greater in PMG than AMG. Conclusion: Both mechanics result in increased labial tilting, but posterior mini-implants assisted maxillary incisor intrusion is greater, so it is preferred when the patient's incisors is upright position.

Maxillary Incisor Intrusion Using Mini-Implants and Conventional Intrusion Arch: A Systematic Review and Meta-Analysis.

The aim of this analysis was to evaluate the maxillary incisor intrusion and change in overbite achieved by micro-implants compared to Connecticut intrusion arches among post-pubertal patients with deep bite. Medline, PubMed, Cochrane, and Google scholar were searched for studies falling under the inclusion criteria. Randomized controlled trials (RCTs) and controlled clinical trials (CCTs) com- paring maxillary incisor intrusion among post-pubertal deep bite cases treated by mini-implants and Connecticut intrusion arches were to be included. Outcome data were extracted using guidelines published by the Cochrane Collaboration. A systematic review was conducted using Cochrane Program Review Manager, version 5. A random effects model was used to assess the mean difference in the amount of incisor intrusion and overbite correction achieved between the 2 methods. Statistical significance was set at P < .05. Assessment of certainty of evidence was conducted using GRADE analysis. Six trials met the inclusion criteria. Mean differences for incisor intrusion -0.67 [95% CI, 0.97, 0.38] I2 = 31%; P < .00001) and overbite correction -0.51 [95% CI, 0.85, 0.16] I2 = 50%; P = .004) achieved with mini-implants were found to be significantly effective when compared to the Connecticut intrusion arch. Low to mod- erate heterogeneity was noted for incisor intrusion and change in overbite analysis respectively. High certainty of evidence was noted for higher association of mini-implants with incisor intrusion and overbite correction. Our meta-analysis suggests that mini-implants are superior to the Connecticut intrusion arch with respect to the amount of incisor intrusion and overbite correction. Further studies are still needed to confirm the superiority.

Electron-microscopic study on structural changes of mini-implants following fixed orthodontic treatment

In today's society, patients who turn to the orthodontist want final results in the shortest possible time, with maximum emphasis on smile aesthetics, dental alignment and facial harmony. In this regard, some procedures have emerged to accelerate the movement of teeth through the alveolar bone, thus shortening the duration of active treatment: corticotomy, application of mini-implants, etc. Of these methods, bone anchorage on mini-implants is increasingly popular among adult patients, as it is a versatile technique that ensures a stable, bony anchorage and more predictable final results. Compared to implantology in prosthodontics, which has a long history, mini- orthodontic implants emerged later in medical practice. In 1998, Shapiro and Kokich described for the first time the possibility of using dental implants for anchorage in orthodontic therapy. Odman J et al. (Upsala University, Sweden) applied implants to patients with partial edentulousness. The results were favorable, leading the authors to recommend the technique for adult partial edentulousness. Kanomi (1997) showed that a 1.2 mm diameter titanium mini- implant provides anchorage for the intrusion of the lower front teeth. After 4 months, the mandibular incisors were intruded by 6 mm without root resorption. Birte Melsen et al. (1998) introduced the use of zygomatic ligatures as anchorage in patients with partial edentulousness. To this they attached nickel-titanium springs for intrusion and retraction of maxillary incisors. Hugo de Clerk (2008) used 4 mini-implants (Bollard type) inserted into the infra-zygomatic crest in patients with Angle class III anomalies. He used 2 mini-implants with hooks in the chin area, and patients wore Class III 150 grams elastics on each side. This direct anchorage also has orthopedic effects, with clinicians achieving upper jaw advancement and correction of mandibular prognathism.

A comparitive evaluation of changes in marginal alveolar bone in anterior maxilla caused by maxillary incisors intrusion using miniscrews and utility arch: A 3-dimensional study

Objective: This study was performed to investigate the changes in alveolar bone after maxillary incisor intrusion and to determine the related factors in deep-bite patients. Material and Methods: 20 maxillary central incisors of 20 patients were evaluated. The maxillary incisors in Group I (20 patients; mean age, 22±1.32 years) were intruded with a Utility-arch, while those in Group II (10 patients; mean age, 20±2.71 years) were intruded with miniscrews. Changes in the alveolar envelope were assessed using pre-intrusion and post-intrusion CBCT. Labial, palatal, and total bone thicknesses were evaluated at the crestal (3 mm) and mid-root (6 mm) levels. BACH, PACH, and BBH was evaluated. Paired t test was performed for quantitative variables. Results: Upper incisor inclination and intrusion changes were significantly greater in Group II than in Group I. Conclusions: Change in the labial inclination and the amount of intrusion should be considered during upper incisor intrusion, as these factors increase the risk of alveolar bone loss.

Efficiency of different miniscrew positions for maxillary incisor intrusion: A comparative cone beam study

Aim: To evaluate the treatment efficacy of two different position of mini-implant-assisted methods to intrude the maxillary incisors using cone-beam computed tomography (CBCT). Patients and Methods: The study included 26 patients with elongated maxillary incisors and a deep bite, ranging in age from 12 to 18 years. One group received anterior mini-implants, whereas the other received posterior ones at random. The AMG used elastic chains to apply about 40 g of force per side, while the PMG used beta-titanium wires. This investigation used CBCT scans that were performed before and after an intrusion that lasted 18 weeks. Result: Significant changes in the labial inclination of all incisors, which were greater in PMG than AMG. Conclusion: Both mechanics result in increased labial tilting, but posterior mini-implants assisted maxillary incisor intrusion is greater, so it is preferred when the patient's incisors is upright position.

Effects on root axes and resorption of simultaneous intrusion and retraction of maxillary central and lateral incisors using mini-implant supported three-piece burstone base arch: A prospective observational study

Prospective morphometric evaluation of the positional changes and root resorption of maxillary central and lateral incisors undergoing simultaneous intrusion and retraction (SIR) using mini-implant supported 3-piece Burstone base arch. Bracket head type mini-implants were inserted between the maxillary second premolar and first permanent molar. After maxillary canine retraction, SIR of maxillary incisors was begun using mini-implant supported 3-piece Burstone arch. A segmental CBCT was taken before and after SIR of the maxillary four incisors. Data collected were analysed using Paired t test, ANOVA test, independent sample t test and Pearson's correlation test. Sixteen patients of 17.9±1.94 years mean age with class II division 1 malocclusion, deep bite≥4mm and overjet 5-8mm were selected. All mini-implants showed good stability during treatment with no looseness. Increasing the vertical end of the anterior segment up to 10mm led to controlled tipping and partial bodily retraction of the maxillary central and lateral incisors. The centre of resistance (CRe) of the four maxillary incisors was retracted 2.38±0.77mm and intruded 2.76±1.0mm with a mean change in axial inclination of 9.76±3.45°. The mean amount of root resorption of the four incisors was 1.29±0.59mm over a mean period of 6.2 months. The mini-implant supported 3-piece Burstone base arch had a pronounced effect on SIR of flared maxillary incisors with clinically insignificant amount of root resorption.

Maxillary Incisor Intrusion Using Two Conventional Intrusion Arches and Mini Implants: A Prospective Study

This study aimed to compare cephalometrically the rate of maxillary incisor intrusion using mini implants, Connecticut intrusion arches, and segmental intrusion arches. Thirty-two adult patients with deep bite were divided into three groups: 10 patients in mini implant and Connecticut intrusion arch group each and 12 patients in segmental intrusion arch group. Bilateral mini implants were used for intrusion in Group 1. Connecticut intrusion arch and Burstone's three-piece intrusion arch were used for intrusion in Group 2 and Group 3, respectively. Intrusion was carried out in all the patients for 4 months. Lateral cephalograms were taken just after alignment and leveling (T1) and after 4 months of intrusion (T2). The mean amount of intrusion observed was 1.7 mm (0.425 mm/month) in mini implant group, 1.4 mm (0.35 mm/month) in Connecticut intrusion arch group, and 1.66 mm (0.415 mm/month) in segmental intrusion arch group. No statistically significant difference was found in the extent of incisor intrusion in the three groups (p <0.05). The study failed to reject the null hypothesis, and there was no statistically significant difference in the amount and rate of incisor intrusion achieved among the three groups (p >0.05). Significant amount of incisor intrusion was carried out by all the three methods. There was no statistically significant difference in the amount and rate of incisor intrusion achieved by the three methods. Clinically, mini implants can be considered superior to the conventional techniques as it provides absolute anchorage which eliminates unwanted effects of incisor intrusion.

Accuracy of panoramic and periapical radiographs to assess root resorption after incisors intrusion: A comparative study

Abstract: The aim of this study was to compare the accuracy of root resorption measurement on panoramic and periapical films after intrusion of maxillary incisors using either microimplant anchorage system or archwire of accentuated compensating curve. Patients and methods: 40 patients with age ranging from 18 to 24 years old, were randomly divided into two groups of 20 each. Each group was divided into 2 equal subgroups of 10 each: Subgroup A: comprised panoramic radiographic findings. Subgroup B: comprised periapical radiographic findings. Maxillary incisors were intruded using mini-implants in group I, and accentuated compensating curve arch wire in group II. Root resorption was examined with panoramic radiographs (subgroup A) and priapical radiographs (subgroup B) taken at pretreatment and postintrusion. Results: considering panoramic radiograph, root resorption of the upper incisors using the modified four grade ordinal scale showed that group I had 75% of the teeth classified with score 0, and root resorption score 1 in 25%. Group II had 60% of teeth with score 0 and 32.5% with scores of 1 and just 7.5% with score 2. The difference between both groups was significant (P< 0.05). Regarding periapical radiograph the mean amount of root resorption was significantly high in group II compared to group I. Flaring of incisors in group II is more significant than in group I. Conclusion: During taking panoramic radiograph, patient positioning must be checked to decrease error. Periapical film is preferred in cases when root resorption is expected with significant degrees.

Quantitative Analysis of the Relationship between Maxillary Incisors and the Incisive Canal by Cone-Beam Computed Tomography in an Adult Population of Mangaluru

Background: Maxillary anterior teeth play a crucial role in aesthetics, phonetics, and mastication. For successful orthodontic treatment evaluating the morphology of the alveolar bone and incisive canal would help in avoiding root resorption, dehiscence, and fenestration. This study is aimed to research the configurational relationships among maxillary incisors, alveolar bone, and incisive canal through Cone Beam Computerated Tomography (CBCT). Methods: CBCT images of 35 orthodontic patients were evaluated for length of the canal (L); angles between the palatal plane and the maxillary alveolar border (01),the incisive canal (02), and maxillary incisor (03); distance from the right maxillary incisor to the incisive canal (D). All the measurements were performed on sagittal plane with the exception of (D) which was made on axial plane. Statistical analysis was performed on the above parameters using two sample test and Pearson’s correlation analysis. Results: There was no statistically significant difference between males and females for all the variables although there were large interindividual variation. There was a positive moderate correlation between 01 and 02 (0.480), 01 and 03 (0.487), 02 and 03 (0.345). The mean value for L and D were 10.38mm and 4.14mm respectively. Conclusion: There exists a large interindividual variability for incisive canal, proximity of incisors with that of incisive canal which could not be precisely predicted by the conventional cephalograms. The results of the study could be helpful clinically in planning orthodontic treatment for significant intrusion and retraction of maxillary incisors
