Improving Decision-Making for Missing Upper Front Teeth

15. juni 2026 opdateret af: King's College London

Development of a Patient Decision Aid for the Treatment of Maxillary Lateral Incisor Agenesis

Background: The developmental absence of 1-2 upper front teeth is a common condition, affecting 1 in 50 people worldwide, and affects smile aesthetics and quality-of-life. Treatment is often undertaken in teenagers, but the outcomes have lifelong consequences. Treatment options involve either creating space for a false tooth, or closing space and disguising the adjacent tooth as the missing tooth; both options have their own advantages, disadvantages and long-term considerations, and treatment often requires input from multiple dental specialties. Advances in orthodontic techniques mean more patients can be treated with either approach, therefore, the ideal treatment plan becomes more subjective and based upon the patient's preferences.

Aim: To develop a Patient Decision Aid (PDA), a decision-making support tool to help young people (and parents/guardians) with developmentally missing upper front teeth choose the best treatment option for them.

Approach: First, the investigators will gather information from stakeholders involved in the decision-making process to understand their needs. Interviews will be conducted with young people with developmentally missing upper front teeth and their parents/guardians about their experiences, expectations, and preferences regarding treatment decision-making. Information will also be sought from clinicians involved in this process about their experiences of the decision-making process, via focus groups. These will be carried out across two NHS hospitals with special clinics for missing teeth. Then, the information obtained from both patient and clinician stakeholder groups will help the investigators to develop a PDA, following international guidelines. PDA development will occur alongside ongoing input and feedback from a Development Panel (which will include patients and clinician representatives) to optimise content, acceptability, and accessibility. The final approved PDA will then be trialled in a later pilot study.
