molars going into adulthood. However, leaving the primary teeth in place may run the risk of tooth infraocclusion where the occlusal surface is below that of adjacent teeth. Despite this, the retention of primary teeth, particularly molars, are more susceptible to occlusal wear, over-eruption of opposing teeth and the loss of inter-occlusal space. Orthodontic space closure Orthodontic space closure is a way of using orthodontics in order to close spaces in the mouth where the teeth are missing. The ideal age for definitive orthodontic treatment is early adolescence but it is important to consider the patient's age, severity of hypodontia, patient expectations and their commitment to treatment. It can be an option for hypodontia management in the case of missing maxillary lateral incisors through the reshaping, and mesial re-positioning of the adjacent canine. This management is indicated in hypodontia cases of Class I molar relationship with severe crowding in the mandibular anterior region where the extraction of lower premolar leads to a predictable outcome, and Class II molar relationship in the absence of crowding and protrusion of the mandibular anterior dentition. When moving the canine into the space of the lateral incisor, the dimensions of the canine, root position and gingival position differ from a lateral incisor and therefore preparation of the canine is necessary in order for it to mimic the incisor. This may involve: Reduction of the incisal tip and addition of composite on the incisal edge to create a straight contour and a rounded disto-incisal corner Reduction of the mesial and distal surfaces to reduce the width of the tooth Flattening of the labial surface to reduce bulbosity. However, removal of enamel by expose the darker coloured dentine and therefore further restoration may be required. Preparation of the palatal surface of the canine to reduce its bulk. The use of veneers can also be used instead of composite however, these are more expensive and more time-consuming. There have been several studies which showed the advantages of orthodontic space closure without prosthodontic space replacements. The main advantage mentioned is the early completion of the treatment during early adolescence and the long lasting result of the treatment outcome. In individuals with a high smile line, the mesial re-positioning of canine maintains the normal soft tissue architecture is important in maintaining the aesthetic appearance. This option also negates the risks and costs that comes with prosthodontic treatment and the impression
