Introduction: A beautiful smile is a facial expression of grave importance as it relates to communication and expression of one’s own feelings and emotion. Planned orthodontic evaluation of smile using Digital Smile Design Software is helpful in determining the final 
treatment goal of obtaining every criterion of the American Board of Orthodontics along with an esthetic smile.
Aim: To digitally evaluate smile based on hard tissue component in Class-I, Class-II division 1 and Class-II division 2 malocclusion.
Method- For each patient, a series of photographs required for DSD analysis will be performed. The facial aspects, smile harmony and dental characteristics will be evaluated. The hard tissue component of beautiful smile in Class-I, Class-II division-1 and Class II Division-2 cases is evaluated, compared and corrected accordingly.
Results- Chi square test, student unpaired t-test, students t test & ANOVA test will be utilised to analyse data. Comparison of the hard tissue component of beautiful smile in Class-I, Class-II division-1 and Class II Division-2 cases will be done usng t-test. When all parameters will be assessed norms for each cases will be obtained.
Conclusion- Digital evaluation of smile before beginning of any procedure can help to achieve treatment goals.

American academy of orofacial pain stated that, TMD is referred as a combined term taking up a variety of clinical problems that involve the masticatory musculature, the TMJ and associated structures or both.
A variety of therapeutic modalities have been proposed for the management of TMD‟s, such as orthopaedic stabilization, intraoral appliances, behavioural therapy, physiotherapy, pharmacological modalities and jaw exercise and collective treatment [1]. “Splint” can be several apparatus, appliance or device employed to provide stabilization or support of teeth or bones, or generally to resist motion or displacement of fractured or 
injured structures (Glossary of orthodontic terms). [2] Classification of occlusal appliances. According to Okeson [3] is Stabilization appliance, Anterior repositioning appliances (ARA) and other types such as Anterior/Posterior bite plane, Pivoting appliance, Soft/ resilient appliance (silicone) . There are different methods for fabrication of appliances and it will depend on the type of appliance‟s mode of action. Different materials are available to make these appliances. Flexibility of appliance will depend on the material used (acrylic, transparent thermoplastic material). Different splints have different drawbacks which should be taken into consideration before delivering it.
A 1990 survey of a random sample of 10,000 members of the American Dental Association (with a 25 percent response rate) identified splint therapy as the most used treatment modality.
Purpose of this study is to review information regarding different studies carried out to see which type of splints used in treatment of TMD and to give clinician proper splint that can be deliver for specific problem. This article, review's the narrative in relation to Occlusal Splint in Management of Temporomandibular disorders (TMD).

Introduction- As we know that form follows function, the altered nasorespiratory function can lead to altered craniofacial growth. This predisposes to mouth breathing, OSA, adenoid hypertrophy which are a matter of grave importance today. Many orthodontic procedures may lead to reduced lower airway space if underlying conditions are not paid enough attention to. This forces the orthodontist to be more precise in their diagnosis and treatment planning especially planning formulated in accordance with obstructive sleep apnoea. The early diagnosis and early intervention of these conditions can prevent more severe associated problems. There are multiple evaluations of airway status undertaken by anesthetist and ENT surgeon some of which may benefit orthodontist for timely intervention. These methods include roentgenograms, CT,CT bronchography, virtual bronchoscopy, MRI, 3D printing, Ultrasonography, Nasal endoscopy, rhinomanometry. CBCT and lateral cephalogram are the most commonly used diagnostic tool for airway analysis. The reliability of lateral cephalogram in the analysis of airway has been questioned several times in the past few years which puts up a need for evaluation of the technique and its reliability.
Objective- The aim of this article is to review all those literatures that relate to upper airway analysis using Lateral cephalogram to those of CBCT scans and to evaluate the reliability of lateral cephalogram. 
Conclusion- Lateral cephalogram can be used as an initial diagnostic aid for the analysis of airways. Although the three-dimensional airway is analysed using two-dimensional technique it is nonetheless an appropriate diagnostic tool for airway analysis.
