This is the second article in a series on conundrums in orthodontics. A Class I molar relationship is a frequent aim of orthodontic treatment. There are, however, examples where intentionally finishing to a Class III molar relationship is the more pragmatic and preferable option. Pursuing this approach in the appropriate circumstances may, for example, prevent deleterious consequences to the facial profile or avoid the need for further dental extractions. This article explores the indications for finishing cases to a Class III molar relationship with illustrated clinical cases. CPD/Clinical Relevance: Dogmatic attempts to deliver Class I molar relationships, in all cases, without consideration of the consequences, have the potential to cause the patient harm. The orthodontist must then consider all possible options available, including those resulting in a Class III molar relationship.

<p>This case report describes the treatment of a 12-years-old female with a Class III skeletal profile and dental malocclusion. The clinical examination showed concave profile, class III dental relationship, buccal crossbite on the right side, and mild crowding. The cervical vertebral maturation analysis showed the patient was on the CS3 stage. The class III malocclusion was treated with combination of banded rapid palatal expander and face mask followed by non-extraction orthodontic treatment with self-ligating system. Banded rapid palatal expander and face mask were used to improve the skeletal discrepancy. Class I maxilla-mandibular relationship was achieved along with class I molar, incisor, and canine relationship. The buccal crossbite and mild crowding were corrected, the overbite and overjet were normal, and the facial profile was improved. This case demonstrates a good result of a class III malocclusion treatment in an adolescent patient with banded rapid palatal expander/face mask and self-ligating system.</p>

Class I malocclusion also called neutro-occlusion, this describes a normal molar relationship but there is malposition of one or more individual teeth. Treatment of Class I malocclusion varies depending on the condition and severity. However, the purpose of this report is to review the orthodontic treatment of a Class I malocclusion with buccally placed canine without extraction. This case report describes a 13-year-old girl with a Class I malocclusion, anterior and posterior crossbite, a retrusive maxilla with high canine. The Class I malocclusion with posterior crossbite was corrected with quad helix followed by non extraction orthodontic treatment with fixed appliances to correct anterior crossbite. At the end of treatment we obtained an acceptable occlusion relationship and the facial profile and the patient's smile were improved substantially.Ban J Orthod & Dentofac Orthop, April 2014; Vol-4 (1-2), P.20-22

Background: Hypodontia is one of the most common anomalies in dentistry. Hypodontia has a negative impact on oral health-related quality of life with patients best seen in a multidisciplinary clinic to improve treatment outcomes. Aim: To investigate the prevalence of hypodontia and its association with other dental anomalies, as well as malocclusion, and to investigate the treatment planned for patients attending the clinic and whether the type of missing teeth affected the proposed treatment. Materials and Methods: Analysis of consecutive patients attending the hypodontia clinic at a dental hospital between February and November 2020. A total of 100 patients who met the inclusion criteria were identified. Data collected included the following: age/sex; number and type of missing teeth; pre-treatment occlusion; presence of other dental anomalies; and planned treatment. Results: A total of 100 patients (55% female; age range = 7–41 years; mean age = 18 years) were included. Of the cohort, 47% had a class I skeletal relationship and participants were significantly less likely to have a class III skeletal or incisor relationship; 45% had another dental anomaly with the most common being microdontia. Space opening was the preferred treatment option for those managed by orthodontic treatment with resin-bonded bridges most likely to be used for restoration of spaces, 86%. Conclusion: Lower second premolars were the most commonly missing teeth. Participants were significantly less likely to have a class III incisor or skeletal relationship than class I or II. Space opening was the favoured approach for orthodontic treatment, particularly for maxillary lateral incisors.

Crossbite is one of the most prevalent malocclusion, posterior crossbite occurs in 8% to 22% of orthodontic cases and anterior crossbite has been seen in Class III cases, which accounts for 3.4% of orthodontic cases. The etiology of posterior crossbite can include any combination of dental, skeletal, and neuro muscular functional components, but the most frequent cause is reduction in width of the maxillary dental arch. Patients/cases seeking comprehensive orthodontic treatment in between 5 to 35 years were diagnosed for crossbite with diagnostic model and care record file. Out of 300 cases 163(54.3%) had crossbite, 90(30%) had anterior crossbite and 109(36.3%) had posterior cross bite. Among posterior crossbite 60(20%) had unilateral and 49(16.3%) had bilateral crossbite. Posterior crossbite was more prevalent than anterior crossbite. Cases with Class I molar relation showed more crossbite. Crossbite was more prevalent in cases with congenitally missing teeth.Bangladesh J Medicine Jan 2015; 26 (1) : 9-12

Objectives: To calculate the agreement between the Dental Aesthetic Index (DAI) and the Index of Complexity, Outcome and Need (ICON) in assessing orthodontic treatment need and to determine correlations between the Peer Assessment Rating (PAR) and DAI and ICON scores according to Angle classification among patients referred for orthodontic evaluation. Study Design: This study included 457 randomly selected patients between 9 to17 years of age. Patients were divided into four groups according to Angle classification [Class I (n=154), Class II division 1(Class II/1) (n=155), Class II division 2(Class II/2) (n=52) and Class III (n=96)]. Relationships between PAR scores and ICON and DAI scores were evaluated with the Spearman correlation test. Unweighted kappa statistics were used to analyse agreement between the ICON and DAI on the need for treatment, according to Angle classification. Results: Class I malocclusions scored significantly lower than other Angle classifications in all indices. Both the ICON and DAI showed significant positive correlations with the PAR in the general study population. For Class II/2 patients, no correlation was found between PAR and DAI scores. There was significant agreement between the ICON and DAI on treatment need among Class I, Class II/1 and Class II/2 patients however, no agreement was found for Class III malocclusions. Conclusions: The ICON, DAI and PAR produce similar results and can be used interchangeably for the general orthodontic patient population. However, based on Angle classification, prominent differences exist in scoring certain occlusal features.

Abstract Background. The epidemiology of the population living in a country plays an important role in the planning and implementation of dental services. Correct identification of the need for orthodontic treatment in individuals is a very complex subject and requires detailed analysis. The aim of this study was to measure the prevalence of malocclusion among randomly selected subjects aged 12-15 years attending secondary schools regardless of any socio-economic or social status in Northern Cyprus.Methods. After the approval of the competent authorities in the Ministry of National Education and the Ministry of Health of Northern Cyprus and of the parents whose subjects were to take part in the study, the evaluation was carried out by a team of three people, two of whom are in the process of specializing in orthodontics and one doctoral student at the qualification stage. The study included a randomly selected sampling composed of 426 subjects (203 females and 223 males). Results. The statistical evaluation of the samples collected in the study found that 20.6% of the subjects had no occurrence of occlusion, 74.4% had Class I, 21.1% had Class II (part 1, 18.8%, part 2, 2.3%) and 4.5% had Class III malocclusion. Of the 419 patients, 86 (20.2%) were in need of orthodontic treatment. Although not statistically significant, it was determined that 19.7% of female patients and 20.7% of the male patients were in need for orthodontic treatment.Conclusions. The most common orthodontic malocclusion in Cyprus is Class I, the least common malocclusion is Class II division 2.

Aims This study aims to find the prevalence of orthodontic treatment need and malocclusion problems in 8–9-year-old schoolchildren in the south of Thailand. Materials and Methods A number of 202 children (100 boys and 102 girls) samples were randomly selected from all schools in Hat Yai District, Songkhla Province, Thailand. A cross-sectional survey of dental health component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and malocclusion problems was investigated by clinical examination and dental model. Results Levels 4 and 5 of orthodontic treatment need according to DHC of IOTN of the sample were presented in 18.8% and 1.49%, respectively. Children who need orthodontic treatment (Grade 2–4) showed more than one highest DHC problem that indicated the level of treatment need (39.68%). Normal occlusion was found at 6.43%. Malocclusions such as Class I, Class II division 1, Class II division 2, and Class III malocclusion were observed in 78.71%, 7.92%, 3.47%, and 3.47%, respectively. Reversed overjet and overjet >9 mm were detected in 5.64% and 1.58%, respectively. Approximately half of the children (46.67%) had overbite >3.5 mm. Conclusions High percentage of children in mixed dentition period who need orthodontic treatment was found in this study. Some children who presented with the orthodontic treatment need Grade 2–4 had more than one DHC problem which identified the grade of treatment need. Class I malocclusion was most frequently found in this group of children.

BACKGROUND To provide efficient and well-planned orthodontic treatment orthodontists must be able to assess the type of malocclusion and the complexity involved in its treatment. Hence, the purpose of this study was to validate index of orthodontic treatment complexity (IOTC) as a reliable index to assess the treatment complexity in treating different malocclusion groups. METHODS A retrospective study with sample of 120 pairs of orthodontic study model consisting of treated and untreated cases, were collected and equally divided into class I, class II including both division 1 and division 2 and class III malocclusions based on Angles system of classification of malocclusion. Study casts were scored according to criteria given by the index of orthodontic treatment complexity and the degree of complexity is established for each of the malocclusion groups and the occlusal traits. RESULTS The Spearman correlation coefficients test shows that occlusal traits like overjet, centreline discrepancy, molar correction, overbite, crowding, posterior cross bite, alone significantly correlated with degree of complexity. Multiple regression analysis and one way ANOVA tests were performed for the three types of malocclusion and the test showed that in individual classes of malocclusion, the predictor variable (occlusal traits) significantly predicts the degree of complexity in class I and class II malocclusion cases, but not in class III. CONCLUSIONS Overjet, centreline discrepancy, molar correction, overbite, crowding, posterior cross bite correlated with degree of complexity. IOTC forecasts the degree of complexity in class I and class II malocclusion cases, but not in class III. KEY WORDS IOTC, Malocclusion, Occlusal Traits
