简要总结
BACKGROUND: Alginate impressions have long been a staple in orthodontics, but with recent technological advancements, digital impressions via intraoral scans are gaining increasing popularity. While much research has focused on patient preference and the accuracy of these techniques, there is a notable gap in the literature regarding chair side time and associated costs. Existing studies on chair side time comparisons between alginate impressions and intraoral scanning yield inconsistent results, underscoring the need for further investigation. This study aimed to evaluate the chair side time and cost implications of intraoral scanning and alginate impressions.
OBJECTIVES: The primary objective is to compare the chair side time taken for alginate impressions and intraoral scanning of orthodontic patients aged 9 years and over in an orthodontic department at a district general hospital. The secondary objective is to evaluate the costs associated with alginate impressions and intraoral scanning of orthodontic patients described above.
DESIGN, SETTING AND PARTICIPANTS: A prospective, single-centre, parallel-arm randomised controlled trial (1:1 allocation) to be undertaken in a district general hospital. Sixty-eight orthodontic patients aged nine and above, requiring study models, will be recruited during new patient appointments at the Orthodontic Department at Queen's Medical Centre, Nottingham. Patients will be randomly assigned to either the intraoral scan or alginate impression group, with chair side time recorded for each procedure, including retakes. The IOS group will use the 3Shape TRIOS scanner, while the alginate group will follow standard procedures. The costs of each technique will be calculated following the procedure. Ethical approval was obtained from a Health Research Authority Research Ethics Committee.

详细描述
RATIONALE: This research project investigates the evolving landscape of orthodontic practices by comparing the time and cost implications of two prevalent techniques: intraoral scanning and traditional alginate impressions.
Whilst the majority of the existing 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 inconsistent findings, necessitating a comprehensive investigation.
The outcomes of this study will provide crucial insights into the practicality and economic viability of intraoral scanning versus alginate impressions in orthodontic settings, thereby informing clinical practices and facilitating technological assimilation within the United Kingdom. This research contributes to strengthening the evidence base surrounding orthodontic techniques and their implications for patient-centred care.
DESIGN: Prospective single-centre parallel-arm randomised controlled trial, with an allocation ratio of 1:1, to investigate the difference in chair side time and cost of alginate impressions vs intraoral scans.
SETTING: A single-centre study was undertaken in the Orthodontic Department at Queens Medical Centre (QMC), Nottingham University Hospitals NHS Trust.
