Abstract
Objective:In this study, we aimed highlight some clinical features present in patients whose maxillary lateral incisors are missing, and proposed more logical, rational and predictable solutions to inform decision making in rehabilitation procedures.Methods:Literature review and discussion.Conclusion:Choosing the best possible treatment for congenital absence of maxillary lateral incisors depends on the multidisciplinary diagnosis of facial, occlusal, functional and periodontal features. It also depends on the individual long-term stability, and it does not only rely on canine-guided disocclusion.
Highlights
Upper lateral incisors agenesis affects approximately 2% of population
Many alternatives exist, including removable partial denture [5], conventional fixed partial denture [4, 5], fixed partial denture in cantilever [6], adhesive denture [4 - 6], implant-supported denture [7], and orthodontic space closure followed by dental recontouring [3 - 5]
In the presence of a deep bite and when the intrusion of the maxillary central incisors is proposed as orthodontic treatment, maintenance or opening spaces for replacement with implants should be cautiously reassessed, as some intrusion relapse will manifest in the future [47, 48], and the esthetic result can be catastrophic in the long term [19, 20], if a slight gummy smile is present [9, 17]
Summary
Choosing the best possible treatment for congenital absence of maxillary lateral incisors depends on the multidisciplinary diagnosis of facial, occlusal, functional and periodontal features.
