<Li> Resin - bonded bridges: Due to its minimal preparation required, this method of replacing teeth is more suited to young adults . It is a definitive restoration with the ability to fill up one or two tooth spaces .

Restoring teeth with this method can only be done after orthodontic treatment and will need an element of retention to ensure that tooth contacts are not misplaced . </Li> <Li> Conventional bridges: Teeth tend to be prepared for conventional bridgework if there are large restorations present, thus being more commonly done on adult patients with hypodontia . Treatment with conventional bridgework will require significant reduction of tooth structure, which will put the tooth at risk of biological damage i.e. loss of vitality . This risk is especially high in young patients with large pulp chambers . </Li> <P> Autotransplantation involves the removal of a tooth from one socket and relocating to another socket in the same individual . If done successfully, it is able to ensure stable alveolar bone volume as there is continuous stimulation of the periodontal ligament . </P> <P> Placing dental implants has proven to be a predictable and reliable method of treating hypodontia, along with bringing excellent aesthetic results . Implant placement should be delayed until jaw growth in an individual is complete . One limitation of implant placement would be the need for a sufficient amount of bone volume, which if not met, may affect the positioning of the implant . However, bone grafting can be carried out to overcome this . </P>
