Research summary
This research project investigates the time and cost implications of two common techniques in orthodontics: alginate impressions and intraoral scans. Alginate impressions (putty moulds) are a traditional technique that has been used in orthodontic practice for many years. Intraoral scans are a more modern method and are becoming more commonly used in orthodontic practice. Both alginate impressions and intraoral scans are a means of recording a copy of a patient's teeth which aids in record keeping and treatment planning.
Whilst the majority of the available literature reveals patient preference in favour of intraoral scanning, it remains common practice to use alginate impressions for orthodontic records. Considerations such as time implications, device costs, associated software expenses, and the need for clinician training pose challenges to widespread adoption of intraoral scanning. When comparing chairside time taken for intraoral scans versus alginate impressions, there are varying findings, requiring a thorough investigation.
The main question being addressed is:
- Are intraoral scans more time efficient than alginate impressions?
The secondary question being addressed is:
- Are intraoral scans more cost effective than alginate impressions?
This research protocol outlines a clinical trial, evaluating the chairside time and costs associated with intraoral scanning versus alginate impressions. The sample population will be orthodontic patients ages 9 years and above attending the orthodontic department at a district general hospital.
The outcomes of this study will provide important insights into the cost and practicality of intraoral scans versus alginate impressions in orthodontic settings, helping to informing clinical practices within the United Kingdom. This research contributes to strengthening the evidence base surrounding orthodontic techniques and their implications for patient-centred care.
