Cleidocranial Dysplasia of a 13-year-old Bangladeshi Girl: A Rare Case Report

Cleidocranial dysplasia (CCD) is an uncommon autosomal inheritant congenital skeletal defect that primarily affects the bones and teeth, and shows an autosomal inheritance. A 13-year-old Bangladeshi girl presented with delayed eruption of the permanent anterior teeth. She was short-statured, well-oriented young girl with narrow, drooped shoulders, malformed or absent clavicles, brachycephalic head with frontal and parietal bossing, hypoplasticzygomatic bones, bulging calvarium, and depressed nasal bridge with a broad alar base. Intraoral examination revealed persistence of the primary dentition, delayed eruption of the permanent teeth, an Angle class III malocclusion, negative overjet, bilateral posterior crossbite. This rarecase of CCD is so far the first case from Bangladesh to be documented in perspective to dental surgery and orthodontics.

Non-surgical and Non-extraction Orthodontic Treatment of an Excess Reverse Bite with Anterior Open Bite

This 13-year-old female had a severe Angle’s Class III malocclusion with an excessive negative overjet 7 mm, anterior open bite 2 mm, a prognathic chin and a concave lateral profile. But this patient and her parents refused orthognathic surgery. Finally, she was treated with a non-surgical and non-extraction approach. The treatment plan consisted of total distalization of mandibular dentition with bilateral temporary anchorage device (TAD) and maxillary incisor extrusion with vertical elastics. The active treatment period was 34 months. Normal overbite, overjet, and acceptable profile were achieved.

The Reliability of Orthodontic Treatment, According to the Needs of Patients Using the Dental Aesthetic Index

Objectives: Malocclusion was and remains one of the most common problems which affects the psyche and social status of the individual, so the estimation of the malocclusion severity and needs a percentage of orthodontic treatment of Iraqi patients is the aim of this study. Method: A randomly selected 150 pairs of study models (48 male and 102 female) were involved in this study for patients attending an orthodontic clinic at College of Dentistry/ University of Baghdad seeking for treatment. The DAI scores were collected according to WHO guidelines directly from the study model with a digital caliper, score was calculated using the regression equation of 10 occlusal traits. The dental casts were classified into four groups to determine the treatment needs. SPSS software version 25 was used to analyze the results. Results: 8.7% of orthodontic treated patients were with normal or mild malocclusion (DAI?25) and did not need treatment, while 56% of them were handicapped and needed mandatory treatment. In between them, patients with definite and severe malocclusion were 18.7% and 16.6% respectively. Molar deviation (72.6%) represents a high prevalence rate among occlusal traits, while negative overjet (7.3%) is the least one. Conclusions: Not all patients who are treated in an orthodontic clinic are really in need, and it must be the implementation of treatment need index to determine the treatment priority for patients.

Maxillomandibular and occlusal relationships in preadolescent patients with syndromic craniosynostosis treated by LeFort III distraction osteogenesis: 10-year surgical and phenotypic stability

LeFort III distraction osteogenesis may be indicated in the treatment of syndromic craniosynostosis with severe midface retrusion. This study investigates long-term changes in patients undergoing distraction as children, and compares outcomes to an unaffected, untreated control. Fifteen patients (9 males, 6 females) with syndromic craniosynostosis treated by LeFort III distraction at an average age of 4.9±1.5years were identified. Lateral cephalograms at predistraction, immediate, 1-, 5-, and 10-year postdistraction were superimposed using the best-fit of cranial base details. An untreated, unaffected matched control was obtained from the American Association of Orthodontists Foundation Legacy Collection. Differences in landmark location and cephalometric relationships were assessed between time points and between treatment and control groups. LeFort III distraction produced an average advancement of 14.86±5.14mm at A-point and 10.54±3.78mm at orbitale. This advancement produced overcorrection of anteroposterior occlusal relationships and phenotypic correction of midface position. Surgical stability over a 10-year follow-up was excellent. Posttreatment growth was characterized by absent anteroposterior maxillary growth, preservation of dentoalveolar development and maxillary remodeling, and delayed mandibular growth. Subsequent growth resulted in a long-term phenotypic relapse of pretreatment Class III maxillomandibular relationship and negative overjet. LeFort III distraction osteogenesis produces stable advancement of the midface. Overcorrection is required for long-term phenotypic stability because of deficient postdistraction sagittal midface growth. Late mandibular growth contributes to underestimation of the amount of distraction required to produce long-term phenotypic correction.

Cephalometric features of Angle class III malocclusion with different dentoalveolar compensation (retrospective study)

Introduction: This study was to investigate dentoalveolar compensation in untreated skeletal Class III patients. Methods:This retrospective study was conducted on 102 untreated Class III malocclusion patients. They were divided into group 1 (overjet<0mm, n=51) and group 2 (overjet ≥ 0mm, n=51). Twenty-six cephlometric readings were compared between the two groups. Correlation analysis was performed between the overjet with skeletal and dental measurements and Regression analysis was performed to determine the overjet. Results: The results showed a significantly higher SNB, S-N-Pg, gonial angle and L1-NB mm in the negative overjet group. While, the ANB angle, angle of convexity, Wits appraisal, bony chin and U1- A-Pg mm were significantly higher in the positive overjet group. However, no statistically significant difference was found in the rest of the readings. Correlational analyses showed that the overjet has significant negative correlation with SNB, S-N-Pg, L1-Frankfort, gonialangles. On the other hand, it had significant positivecorrelation with ANB angle, angle of convexity, Wits appraisal, bony chin, L1-MP angle and U1-A-Pg mm. Nine regression equations for the overjet were calculated with the highest coeffcient of determination of 0.33. Conclusion: Dentoalveolar compensation was seen in Class III cases with less skeletal discrepancy, lower mandibular prominence, larger bony chin, greater angle of convexity and smaller gonial angle. Moreover, the position of the maxillary and mandibular incisors on the basal bone, rather than their inclination, contributed in dentoalveolar compensation

Surgery-first orthognathic treatment of an adult patient with unilateral cleft lip-palate and multiple missing teeth: a case report

Introduction: The comprehensive treatment approach and outcomes of a patient with cleft lip and palate was presented in this casereport.Case presentation: A 31-year-old man with unilateral cleft lip and palate(UCLP) had a chief complaint of his mandibular prognathism andasymmetric smile. His clinical and radiographic evaluation showed a Class III skeletal relationship, multiple missing teeth, mandibularanterior occlusal canting, 6 mm of negative overjet and 16 mm overbite. "Surgery first orthognathic approach" was planned including,short-term orthodontic treatment, maxillary advancement and segmental mandibular subapical osteotomy.Conclusion: At the end of the treatment, a functional occlusion, a harmonious profile, and patient satisfaction were achieved.

Prevalence of malocclusion, oral parafunctions and temporomandibular disorder-pain in Italian schoolchildren: An epidemiological study.

The prevalence of malocclusion, temporomandibular disorders (TMD) and oral parafunctions is highly debated in children population. To investigate the prevalence of malocclusion, self-reported oral parafunctions and TMD-pain in Italian schoolchildren and to assess the association between the examined factors. A total of 700 children aged 9-11years were selected among six public schools in Campania region (Italy). Molar relationship, overjet, overbite and cross-bite were assessed through a clinical examination. Furthermore, the subjects were demanded to fill in a validated questionnaire for TMD-pain screening and the short form of the Oral Behaviours Checklist. Descriptive statistics were used to report the frequencies. The associations between occlusal traits, oral parafunctions and TMD-pain were analysed with a Pearson chi-square test, as expressed by odds ratio and 95% confidence intervals. The significance level was set at P<0.05. Molar Class I was the most frequently encountered molar relationship, followed by molar Class II, subdivision and molar Class III. Increased overjet was more common than negative overjet. Posterior cross-bite was observed in 12% of children. TMD-pain was recorded in 14.7% of subjects. High frequency of oral parafunctions was reported in 21.3% of subjects. A significant association was found between TMD-pain and negative overbite. Cross-bite and high frequency of oral parafunctions were associated with TMD-pain. The current results show that malocclusion, self-reported oral parafunctions and TMD-pain are frequent findings among Italian schoolchildren and that some occlusal factors and high frequency of oral parafunctions might be associated with TMD-pain.

Mordida Cruzada Anterior: possibilidades de tratamento na dentição decídua e mista

Anterior crossbite (MCA) refers to a malocclusion whose vestibularlingualrelationship between upper and lower incisors is abnormal,with a negative overjet. This alteration may promote impairment ofdento-facial aesthetics and functions of the stomatognathic system.The MCA can be classified into 3 types: Dental (MCAD), Functional(MCAF) and skeletal (MCAE). The objective of this literature reviewwas to present the different possibilities of MCA treatment in thedeciduous and mixed dentitions. The treatment of MCAD aims atcorrecting the abnormal inclinations of the involved elements. Thetreatment of MCAF can be performed with composite as an inclinedplane tracks recommended by Planas. The MCAE approach aimsat skeletal correction and depends on the degree of bone dysplasiaand the age at which treatment begins. According this study, we canconclude that the MCA should be treated as soon as diagnosed, bythe different forms of treatment presented, according to etiologyand clinical presentation. All the proposed treatments may have highsuccess rates if correctly planned and executed.

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, 46years; 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 and approximately 22% of the variability in overbite. Overjet was related more significantly to upper and lower anteroposterior lip position, and upper and lower facial height (P<0.05). Overbite showed a stronger association with anteroposterior position of the lower lip, pogonion, and soft tissue B-point (P<0.05). Soft tissue profile was weakly to moderately correlated with severity of overjet and overbite in the entire sample. However, in subjects with negative overjet (mandibular prognathism), this association was highly significant.

Sagittal Craniosynostosis and Related Cranial Anomalies: Genetic Insights

BackgroundSagittal craniosynostosis (scaphocephaly) is a pathologic condition that results in premature fusion of the sagittal suture restricting the transverse growth of the skull leading to elevated intracranial pressure and consequent neurodevelopmental delay. It can occur most commonly as an isolated event resulting in nonsyndromic craniosynostosis, or it can occur less commonly in conjunction with other anomalies resulting in syndromic craniosynostosis. Although in past years close attention was paid by researchers regarding the mechanisms that govern development of craniosynostosis, much more remains to be learned about this cranial anomaly, in particular, the genetic mechanisms associated with scaphocephaly. The clearer understanding of the latter not only could shed more light on the respective mechanisms but could also help to improve and predict better outcomes of the respective corrective clinical procedures.ResultsThe present study reports a unique case of a male cadaver 56 years of age with sagittal craniosynostosis with a 0.56 cranial vault index as measured from respective radiographic images. Upon closer examination of the individual's head it was concluded that he underwent, most likely early in his life, a sagittal strip synostectomy with replacement. The additional maxillofacial anomalies included edentulous, mandibular prognathism with class 3 malocclusion and 15 mm of negative overjet, and exostosis of the hard palate. The latter was preliminary characterized as torus palatinus. One of the most interesting features of the present case was the abnormal appearance of the replacement bone strip and its vertical displacement that were accompanied by a presence of abnormal dura and venous sinuses with no brain indentations on the dural surface of the strip. Histologic analyses of cranial soft and hard tissues should help to clarify a nature of the respective pathologies. In order to better understand molecular mechanism(s) responsible for the development of sagittal craniosynostosis with the particular maxillofacial anomalies, the gene coding region (exome) of DNA extracted from the cadaveric tissue was screened for putative mutations employing Illumina Next Generation Sequencing Platform. This will help to unveil new genetic variations associated with the aberrant skull development in humans and optimize clinical approaches for its correction.ConclusionThe current case most likely represents syndromic sagittal craniosynostosis where surgical intervention was mainly unsuccessful resulting in abnormal development of the replacement bone strip and intracranial tissue.Support or Funding InformationThis study was supported by the Center for Anatomical Science and Education, Department of Surgery, Saint Louis University School of Medicine.This abstract is from the Experimental Biology 2018 Meeting.

The role of occlusion in temporomandibular disorders (TMD) in the Northern Finland Birth Cohort (NFBC) 1966

ObjectiveTo investigate the role of occlusion in temporomandibular disorders (TMDs) in the Northern Finland Birth Cohort 1966 (NFBC 1966).MethodsSubjects (n = 1962) participated in clinical medical and dental examinations. The association between TMD signs and diagnoses with occlusal disturbances, i.e. malocclusions and occlusal interferences, was examined. Pearson’s chi-square test, as expressed by odds ratios (OR) and 95% confidence intervals (CI) and logistic regression models, were used in the analysis.ResultsA statistically significant association was found between myalgia and lateral scissor bite and also between arthralgia and lateral deviation in the retruded contact position and intercuspal contact position (RCP-ICP) slide. Pain in the masticatory muscles was associated with negative overjet and the amount of RCP-ICP slide.DiscussionOcclusal factors showed a statistically significant association with TMD. The TMD signs were associated with unstable occlusion, especially the amount and lateral deviation in RCP-ICP slide, as well as negative overjet.

Aesthetic and functional outcomes using a multiloop edgewise archwire for camouflage orthodontic treatment of a severe Class III open bite malocclusion

Occasionally, orthodontists will be challenged to treat malocclusions and skeletal disharmonies, which by their complexity one might think that the only treatment alternative is the surgical-orthodontic approach. A male patient, aged 17 years old, was diagnosed with a skeletal Class III malocclusion, anterior open bite and negative overjet. An unpleasant profile was the patient's 'chief complaint' showing interest in facial aesthetics improvement. Nevertheless, the patient and his parents strongly preferred a non-surgical treatment approach. He was treated with a multiloop edgewise archwire to facilitate uprighting and distal en-masse movement of lower teeth, correct the Class III open bite malocclusion, change the inclination of the occlusal plane and obtain the consequent morphological-functional adaptation of the mandible. The Class III malocclusion was corrected and satisfactory changes in the patient's profile were obtained. Active treatment was completed in 2 years, and facial result remained stable at 2 years 6 months after debonding.

Apnea obstructiva del sueño: un abordaje innovador mínimamente invasivo mediante distracción de rama mandibular

An innovative and minimally invasive approach for adult obstructive sleep apnoea by using bilateral internal ramus distraction osteogenesis of the mandible is presented. After a careful virtual 3D planning, mandibular distraction surgery is performed under general anaesthesia and endoscopic assistance, using a major ambulatory surgery protocol, with the patient being discharged home the same day. After an initial latency of 5days, the ascending ramus is gradually lengthened vertically during a period varying between 10 and 50 days, at a rate of 0.5mm to 1mm daily, until an apnoea-hypopnoea index below 5/h is achieved (cure level), and/or a negative overjet>10mm is reached.Titration of the procedure according to clinical criteria with the assistance of polygraphy and/or polysomnography allows the clinician to customise the mandibular advancement to each particular case. After a mandibular ramus lengthening ranging between 10 and 25mm, the distraction devices are kept in place for 6months after completion of the consolidation period.Bilateral internal ramus distraction is a highly effective surgical technique in curing obstructive sleep apnoea in adults with or without retrognathia, and could be indicated even in patients with comorbidities, such as cardiovascular disease or morbid obesity, in which a major surgical procedure, i.e. conventional maxillomandibular advancement, should be discouraged.

Genetic polymorphisms underlying the skeletal Class III phenotype.

Our goal was to verify the association between candidate polymorphisms and skeletal Class III malocclusion in a well-characterized homogeneous sample set. Thirty-five single-nucleotide polymorphisms were studied from 10 candidate loci in 54 Class III subjects and 120 controls. Skeletal ClassIII characteristics included ANB angle less than 0°, SNB angle greater than 83° (mandibular prognathism), SNA angle less than 79° (maxillary deficiency), Class III molar relationship, and negative overjet. Inclusion criteria for the controls were ANB angle between 0° and 4°, Class I molar relationship, and normal overjet. Chi-square and Fisher exact tests and principal component (PC) analysis were used to determine overrepresentation of marker alleles with alpha of 0.05. Odds ratios and 95% confidence intervals were calculated. MYO1H (rs10850110 A<G) (P<0.01; odds ratio, 7.44 [4.02-13.77]) was associated with an increased risk for the mandibular prognathism phenotype. These results were confirmed by PC analysis, which showed 4 PCs representing the sample variations (PC1, 37.24%; PC2, 20.02%; PC3, 12.18%; and PC4, 11.40%), and PC1 was associated with MYO1H (P<0.001). We also foundby PC analysis associations between MYO1H (P<0.001) and GHR (rs2973015 A>G) (P=0.001) with PC2 and between FGF10 (rs593307 A<G) (P=0.001) with PC4. Polymorphism in MYO1H could be used as a marker for genetic susceptibility to Class III malocclusion with mandibular prognathism, and polymorphisms in GHR and FGF were associated with maxillomandibular discrepancies. This study may contribute to improved diagnosis and further research assessing possible differences in treatment responses based on genetic polymorphisms.

Retrospective 25-year follow-up of treatment outcomes in angle Class III patients : Early versus late treatment.

ObjectivesTo assess early versus late treatment of Class III syndrome for skeletal and dental differences.MethodsThirty-eight Class III patients treated with a chincup were retrospectively analyzed. Baseline data were obtained by reviewing pretreatment (T0) anamnestic records, cephalograms, and casts. The cases were assigned to an early or a late treatment group based on age at T0 (up to 9 years or older than 9 years but before the pubertal growth spurt). Both groups were further compared based on posttreatment data (T1) and long-term follow-up data collected approximately 25 years after treatment (T2).ResultsEarly treatment was successful in 74% and late treatment in 67% of cases. More failures were noted among male patients. The late treatment group was characterized post therapeutically by significantly more pronounced skeletal parameters of jaw size relative to normal Class I values; in addition, a greater skeletal discrepancy between maxilla and mandible, higher values for mandibular length, Cond-Pog, ramus height, overjet, anterior posterior dysplasia indicator (APDI), lower anterior face height, and gonial angle were measured at T1. The angle between the AB line and mandibular plane was found to be larger at T0, T1, and T2, as well as more pronounced camouflage positions of the lower anterior teeth at T0. The early treatment group was found to exhibit greater amounts of negative overjet at T0 but more effective correction at T1.ConclusionsEarly treatment of Class III syndrome resulted in greater skeletal changes with less dental compensation.

Retrospective 25-year follow-up of treatment outcomes in Angle Class III patients : Success versus failure.

ObjectivesDespite recommendations for early treatment of hereditary Angle Class III syndrome, late pubertal growth may cause a relapse requiring surgical intervention. This study was performed to identify predictors of successful Class III treatment.Materials and methodsThirty-eight Class III patients treated with a chincup were retrospectively analyzed. Data were collected from the data archive, cephalograms, and casts, including pretreatment (T0) and posttreatment (T1) data, as well as long-term follow-up data collected approximately 25 years after treatment (T2). Each patient was assigned to a success or a failure group. Data were analyzed based on time (T0, T1, T2), deviations from normal (Class I), and prognathism types (true mandibular prognathism, maxillary retrognathism, combined pro- and retrognathism).ResultsCompared to Class I normal values, the data obtained in both groups yielded 11 significant parameters. The success group showed values closer to normal at all times (T0, T1, T2) and vertical parameters decreased from T0 to T2. The failure group showed higher values for vertical and horizontal mandibular growth, as well as dentally more protrusion of the lower anterior teeth and more negative overjet at all times. In adittion, total gonial and upper gonial angle were higher at T0 and T1. A prognostic score—yet to be evaluated in clinical practice—was developed from the results. The failure group showed greater amounts of horizontal development during the years between T1 and T2. Treatment of true mandibular prognathism achieved better outcomes in female patients. Cases of maxillary retrognathism were treated very successfully without gender difference. Failure was clearly more prevalent, again without gender difference, among the patients with combined mandibular prognathism and maxillary retrognathism. Crossbite situations were observed in 44% of cases at T0. Even though this finding had been resolved by T1, it relapsed in 16% of the cases by T2.ConclusionThe failure rate increased in cases of combined mandibular prognathism and maxillary retrognathism. Precisely in these combined Class III situations, it should be useful to apply the diagnostic and prognostic parameters identified in the present study and to provide the patients with specific information about the increased risk of failure.

Incisor and molar overjet, arch contraction, and molar relationship in the mixed dentition in repaired complete unilateral cleft lip and palate: A qualitative and quantitative appraisal

To compare the mixed dentition incisor and molar overjet, severity of contraction of the dental arch, and the sagittal molar relationship on the cleft side vs the noncleft side in children with repaired complete unilateral cleft of the lip and palate (UCLP). Orthodontic records taken prior to orthodontic preparation for alveolar bone grafting were screened to select study casts from patients with nonsyndromic repaired complete UCLP who did not have mandibular skeletal or dental asymmetry. The study sample comprised dental casts from 74 children aged 8.9 ± 1 years. Standardized digital photographs were acquired at 1:1 magnification. A coordinate system was developed using digital image-processing software (Photoshop CS4 and Adobe Illustrator). Incisor and molar overjet, Angle's classification, and arch contraction were recorded. Descriptive statistics, paired t-tests, and kappa statistics were used to compare the cleft and noncleft sides. A negative overjet of -1 to -5 mm was often present at the incisors, with greater frequency and magnitude on the cleft side. Class II molar relation was more frequent on the cleft side (61.1%) than on the noncleft side (47.2%). Significantly greater contraction of the cleft side deciduous canine and deciduous first molar was noted, while the difference was very minor at the first permanent molar. Cleft side maxillary arch contraction was most severe in the deciduous canine and first deciduous molar region and progressively less severe in the posterior region of the arch. A greater frequency and severity of negative overjet and Class II molar relationship was seen on the cleft side.

Maxillary Distraction Osteogenesis in Unilateral Cleft Lip and Palate Patients with Rigid External Distraction System.

Aim:Distraction osteogenesis (DO) is a treatment option for patients with maxillary hypoplasia secondary to cleft lip and palate (CLP).Purpose:The aim of this study is to present a technique for maxillary DO using Le Fort I osteotomy with rigid external distraction (RED) system.Subjects and Methods:The patient presented in this paper was an Asian female with CLP aged 13 years and 6 months. She presented with severe midfacial deficiency with a Class III dental malocclusion with a negative overjet and concave facial profile. Cone-beam computed tomography images were recorded preoperatively and the operation performed involved a high Le Fort I osteotomy. The appliance fabricated was banded to upper first molars used for anchorage of the RED system. Distraction of the maxilla was initiated after 7-day latency period.Results:Postoperative cephalometric analysis showed maxillary advancement anteriorly and superiorly, the total distraction treatment period was 10 days. The maxillary advancement was 10.5 mm and the SNA angle increased from 67.5° to 77.9°. Furthermore, the ANB angle changed from −9.8° to 1.6° and the occlusion changed from Class III to Class I. The profile of the face changed from concave to convex and a much better esthetic result was achieved.Conclusion:The study suggests RED system to be a reliable alternative procedure for the treatment of midfacial hypoplasia with or without cleft. Furthermore, it minimizes the risk of the surgical procedure and shortens the operating time.

Non-Surgical Orthodontic Treatment of an Orthognathic Surgical Case

Abstract Introduction: Diagnosis and treatment planning for a skeletal malocclusion that exhibits maxillary retrusion in relation to a prognathic mandible is complex and involves quantification of the skeletal discrepancy while considering the limitations of conventional orthodontic systems. This case report illustrates a highly successful non-surgical orthodontic treatment of an orthognathic surgical case. Case report: The patient, who is a 32 year old female with a maxillary crossbite and negative overjet, successfully completes non-surgical, non-extraction orthodontic treatment in a little over 12 months. Post treatment results show a dramatic esthetic improvement, the elimination of a negative overjet and a stable occlusion with good intercuspation. Conclusion: This case report demonstrates the potential of non-surgical, non-extraction orthodontic therapy for an orthognathic surgical case with a system of braces that utilizes light forces and immediately moves the tooth root (s) to their final position with alveolar bone remodeling and short treatment time.
