Clinical comparison between Multi-Stranded Wires and Single strand Ribbon wires used for lingual fixed retainers

Abstract

Background Long-term retention with fixed retainers with a high success rate seems to be a reasonable solution to minimize or prohibit relapse of orthodontic treatment. Methods Two hundred sixty patients between 13 and 30 years old were recruited for this study. The 0.0175 stainless steel twisted wire (G&H Orthodontics, USA) was compared with a single-strand ribbon titanium lingual retainer wire (Retainium, Reliance orthodontics, USA) was used. When treatment was completed, the retainers were bonded from canine to canine in the mandibular arch of the participants. In the follow-up visits, the patients were recalled every 3 months during the 24 months. Detachments, the time of debonding, and side effects were recorded. Statistical analysis was performed by a blinded statistician using a statistical package for Social Science (SPSS, Version20). After descriptive statistics, Kaplan-Meier analysis was performed to measure the survival rates of each retainer. P value < 0.05 was considered as significant. Results Finally, 138 patients who received twisted wire splint and 112 patients who received ribbon wire were included in the analysis. The average duration of success was about 23 months for twisted wire and ribbon wire, according to the Kaplan-Meier estimates. The analysis showed no significant overall difference between the treatments (p = 0.13). Failure rates in terms of detachments in all groups occurred at the enamel junction, and it was 25 in twisted retainer group (18.1%) and was 10 in ribbon retainer group (8.9%); the Kaplan-Meier analysis test detected a significant difference in the failure rates between the groups (p = 0/006). Conclusions Although the conventional twisted stainless steel wire and single-strand titanium flat metal ribbon wire as fixed orthodontic retainers have the same clinical effects, it was shown that the ribbon wire has less failure in terms of detachments.

What causes failure of fixed orthodontic retention? – systematic review and meta-analysis of clinical studies

“…Ribbon were more prone to breakage, while spiral wires debonded more often. Arash et al 2020 [ 31 ] RCT Comparison of failure rate of two types of fixed orthodontic retainer 260 patients (161 W, 99 M) divided into unequal groups (138–122) 0.0175 stainless steel twisted wire (G&H Orthodontics, USA)Vs.single-strand ribbon titanium lingual retainer wire (Retainium, Reliance orthodontics, USA) Failure rate and timing of failure within 2 years (checked monthly) Failure rates in terms of detachments in all groups seemto have occurred at the enamel junction which is clinicallyobserved the bulk of detached composite, and it was25 in twisted retainer group (18.1%) and was 10 in ribbonretainer group (8.9%), what points out ribbon titanium retainer as more reliable. The average duration of success was ca.…”

“… In case if detachment of retainer was noticed during the visit, the subject was allowed to approach immediately for repair and bond failure was recorded in the upcoming visit.

“…The vast majority of studies demonstrate no problems with introducing and describing the processes of randomization and allocation in patients selection for the study groups as well as in outcome data presentation. A possible risk of selective reporting was found in several studies [ 25 , 27 , 31 – 33 ]. However, it should be pointed out, that there were other risks of bias.…”

“…Growth affects the stability of retention, thus the number of young people in the distribution of the study group could have significantly influenced the results of the research. (Sobouti, Kartal, Rose, Salehi, Arash) [ 30 , 31 , 33 , 35 , 37 ]. Tooth movement resulting from ageing occurs in all subjects, disregarding the positive or negative history of orthodontic treatment.…”

Effect of Self Etch Primer Application on the Bond Failure Rate of a Mandibular Bonded Lingual Retainer

“…However, our search of the literature revealed no study on the effect of SEP use on failure rates in multi-strand wire lingual retainer bonding. The duration of success for the multi-strand wire was reported to be about 23 months [12]. Therefore, the aim in the present study was to examine the effect of SEP application on the bond failure rate of a mandibular bonded lingual retainer over 24 months.…”
