BACKGROUND The Forsus fatigue resistant device (FFRD) appliance is known to correct Class II malocclusion. The disadvantage of it are labial flaring of lower incisors, distalisation and extrusion of maxillary molars, difficulty in procuring the appliances in remote areas and cost. No research has documented the comparison of patient’s experience with FFRD and Sharma’s Class II corrector appliance. Therefore, a questionnaire survey was conducted. METHODS 40 patients having Class II Division 1 malocclusion were included and were divided into two groups- FFRD appliance (group 1, 20 patients) and Sharma’s Class II corrector (group 2, 20 patients). A questionnaire was framed that consisted of 15 questions. Descriptive and analytical statistics was done using SPSS software. The difference in proportions was calculated by chi-square test. The level of significance was set at P < 0.05. RESULTS 30 % of cases in group 2 indicated that the Sharma’s Class II corrector looks good (Q1) as compared to 15 % in group 1. (P = 0.630) 5 % indicated it was not aesthetic in group 2 as compared to 10 % in group 1. 30 % of cases in group 1 indicated that there were problems associated with speech as compared to 0 % in group 2. (P < 0.05). Values were statistically significant. CONCLUSIONS Sharma’s Class II corrector has similar patient acceptance as compared to FFRD appliance with the additional benefit of cost effectiveness. Hence, this can be considered as a better option in treating Class II malocclusion with fixed therapy.

In class II malocclusion, there is an anteroposterior disparity between the upper dentition and the lower dentition, which may or may not be accompanied by a skeletal discrepancy. For orthodontists, this is one of the common malocclusions encountered during clinical practice. This might be due to excess maxillary growth or retarded growth of the mandible or a combination of both. In such types of malocclusion, both the upper and lower airways are affected, the lower one most commonly. Characteristic features seen are a narrow maxillary arch, a proclined upper anterior, and mouth breathing as a developing habit. Also, the position of the condyle in the skeletal type of class II malocclusion plays a vital role in the development of temporomandibular joint disorders. Treating such disparity in a growing individual leads to better results in the long term as well as prevention of malocclusion taking a severe form. Myofunctional appliances are useful for repositioning the mandible as well as the condyle. In adults, extraction of the upper premolars is most commonly done for the correction of class II malocclusion. This provides the patient with a better esthetic appearance. In addition to this, various treatment modalities, such as splint therapy, exercise, and prolotherapy, are beneficial for pain relief and temporomandibular disorder (TMD) correction. This article deals with the characteristics, development, etiology, and comprehensive treatment options of class II malocclusion and its co-relation with the upper and lower airway along with the severity of temporomandibular joint disorders. Repositioning of the condyle in the glenoid fossae is the key to the correction of this disorder.
Developmental anomaly of the maxillary lateral incisors most commonly leads to the occurrence of peg lateral. It is a variant of microdontia where the lateral incisors are smaller than the normal size. This appears as unilaterally or bilaterally. This condition is characterised by the converging of the mesial and distal surfaces forming a cone shape. A variety of treatment options exist for this anomaly including orthodontic treatment, restorative technique and veneer. This case report deals with an individual presenting with peg lateral of the maxillary arch along with midline diastema. The multidisciplinary treatment protocol of orthodontic treatment involving minor tooth movement and space closure in conjunction with a restorative technique for correction was preferred.
Introduction: In the recent years it is observed that there has been increase in the no. of cases of Temporomandibular joint disorder and TMJ pain related problem, many of patients go undiagnosed and may transform into irreversible severe cases if the predisposing factors are present. There are different clinical and radiographical methods of diagnosing TMD cases, and one of the simplest ways to diagnose and categorize a Temporomandibular disorder is Helkimo index. The present study is encouraged to measure difficult airway, in Class II malocclusion with TMD. Materials and Method: The observational study will be conducted in Orthodontics and Dentofacial Orthopaedics department, Sharad Pawar Dental College, Sawangi (M), Wardha in collaboration with department of Radiology, Acharya Vinoba Bhave Hospital. Sawangi (M), Wardha. Total 30 patient in age group of 20 to 50 years, will be selected from the patients coming to Out Patient Department (OPD) of Orthodontics and Dentofacial Orthopaedics, Wardha. MRI of patients with skeletal class II vertical growth pattern and class I malocclusion having temporomandibular joint disorder will be taken and then airway is to be evaluated. Expected Results: It is expected that individuals with skeletal class II vertical growth pattern and class I malocclusion with temporomandibular joint disorder may have a compromised airway. Conclusion: No such study has been carried out to evaluate co-relation of difficult airway and temporomandibular joint disorder. Thus, this study aims to evaluate it in skeletal class II vertical growth pattern and class I malocclusion.
