This risk is especially high in young patients with large pulp chambers. Tooth autotransplantation
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. Implant supported tooth replacement
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. Epidemiology
Hypodontia is less common in the primary dentition, with reported prevalence rates ranging from 0.5% in the Icelandic population to 2.4% in the Japanese population. In the primary dentition the teeth reported as most likely to be missing are the lateral incisors, both maxillary and mandibular. If a deciduous tooth is missing this will increase the risk of an absent successor.In the permanent dentition third molars are most commonly absent, and one study found prevalence rates of between 20–22%. When third molars are ignored the prevalence rate for each tooth varies from study to study. In Caucasian studies mandibular second premolars and maxillary lateral incisors are most often absent. Several UK studies have found the lower second premolar to be most commonly absent.
This can aid in predicting growth changes, allowing dentists, especially orthodontists, to develop a suitable treatment plan. Coupled with that, findings consistent among individuals include:

Anterior hypodontia associated with hyper divergent craniofacial pattern;
A tendency toward a class III malocclusion identified in maxillary hypodontia, and;
Reduced lower posterior facial height in children with posterior and mandibular hypodontia. Associated anomalies
Reduction in coronal or radical dimensions
Retained primary teeth
Ectopic canine eruption
Abnormal morphology such as peg-shaped maxillary lateral incisors and taurodontism, characterized by an enlarged tooth body and roots that are reduced in size
Extracted teeth

Cause
Several theories regarding the aetiology of hypodontia have been proposed in existing literature. There have been various theories mostly looking into genetic and environmental aspects and how they may both be involved. However, the exact cause remains unclear. The extent of individual influences of genetic and environmental factors is still widely debated.Theories regarding the mechanism through which hypodontia occurs can be categorised into evolutional or anatomical.Preliminary studies focused on an evolutionary approach which suggested shortening of the intermaxillary complex and thus shorter arches may contribute to a decrease in number of teeth. This was also suggested in 1945 by Dahlberg using Butlers Field Theory that focused on evolution and development of mammalian teeth into human dentition in an attempt to analyse different of agenesis. In each jaw, four morphological sites were identified (incisors, canines, premolars and molars). The tooth at the end of each region was less genetically stable and hence more prone to absence.
