[KAP-3] Full Mouth Rehabilitation of Severe Hypodontia: A Tale of Two Brothers
[Abstract]
[Introduction]
Hypodontia represents a variant of tooth agenesis that significantly impacts aesthetic and functional aspects of the dentition. The aetiology of this condition is multifactorial, implicating genetic predispositions and environmental influences in its development. Hypodontia is categorized as severe when six or more teeth are absence within the permanent dentition, excluding the third molars. [1]
[Case Summary and Treatment Details]
This case presentation showcases treatment of severe hypodontia affecting two twin brothers. Both the 25-year-old twin brothers attended to us due to aesthetic concerns related to the small teeth size and generalized spacing. Clinical examination revealed absence of multiple permanent dentitions associated with decreased vertical dimension of occlusion. Digital smile design was carried out employing photogrammetric approach to accurately assess and plan the aesthetic restoration, followed by full mouth rehabilitation using fixed indirect restorations to achieve an increased vertical dimension.
[Progress and Discussion]
The treatment for the younger brother was completed, whereas treatment is ongoing for the elder brother. One of the common clinical findings associated with severe hypdontia includes a reduction in lower facial height. Hence, treatment plan frequently aims to restore the height of the lower face while concurrently reorganising the occlusal scheme for functional and aesthetic reasons. [2] The application of photogrammetry allowed the generation of 3D virtual facial model of photorealistic appearance. The integration of virtual model and digital wax up could enhance the treatment by allowing presentation of the aesthetic results from all possible view angles, which will increase the realism of digital smile simulations.
