Highlights
- •The effect of patient transfer on treatment quality and duration was investigated.
- •The American Board of Orthodontics cast-radiograph evaluation was used in the assessment.
- •Transfer patients have longer treatment duration and poorer treatment quality.
Introduction
This retrospective study aimed to evaluate whether there are differences in the duration
of treatment and the quality of treatment results between patients whose entire treatment
process is carried out by a single operator and those patients who are transferred
to a second operator.
Methods
One hundred twenty-three patients whose fixed orthodontic treatments were completed
and included in the study, and their posttreatment plaster models and panoramic radiographs
were used. Fifty-nine of the subjects were transfer patients, and their treatment
was administered by 2 residents (transfer group). For the remaining 64 patients, all
the treatment was carried out by a single resident (control group). Each group was
further divided into 2 groups according to the treatment modality, resulting in 4
groups (nonextraction transfer group [n = 27], extraction transfer group [n = 32],
nonextraction control group [n = 32], and extraction control group [n = 32]). The
quality of the treatment outcomes was evaluated and compared using the American Board
of Orthodontics cast-radiograph evaluation (CRE).
Results
The total mean CRE scores in the nonextraction transfer and nonextraction control
groups were 35.74 and 29.88, respectively. The means of treatment duration in the
nonextraction transfer and nonextraction control groups were 32.7 months and 17.25 months,
respectively. The total mean CRE scores in the extraction transfer and extraction
control groups were 39.53 and 31.41, respectively. The means of treatment duration
in the extraction transfer and extraction control groups were 34.38 and 22.94 months,
respectively. Differences between all the compared pairings were statistically significant.
Conclusions
The transferred patients had longer treatment times and poorer treatment quality than
the control group patients.
