Introduction: The objective of this study is to evaluate the factors favoring the detachment of bonded retainers after multi-band orthodontic treatment, Method: This was a descriptive retrospective study of 26 cases of retention detachments recorded in the dentofacial orthopedics department of the CHU-CNOS in Bamako over a period of 1 year from January 2, 2020 to December 31. 2020. The retainers were all bonded using the direct method using two types of composite. Two types of wires were used in patients. The data collection was made from the files of the patients followed in the service. Results: We counted 19 maxillary and 7 mandibular retainers. 19 retainers (73.1%) were bonded with fluid composite retainer and 7 retainers (26.9%) were bonded with normal restorative composite. The type of yarn used is solid yarn in 15 restraints and braided yarn was used in 11 restraints. There is less disbondment with the flowable bonding composite than with the dental restorative composition. Conclusion: The type of suture and the type of composite used seem to have an impact on the durability of the bonded retainer, without significant results.
