Failure Rates of Upper Bonded Retainers Can Be Pretty High Upper Bonded Retainers: Survival and Failure Rates
نویسنده
چکیده
Design/Methods: This was a retrospective analysis of the 1-year survival rate of maxillary lingual bonded retainers. A sample of 466 consecutively bonded retainers was evaluated over a 1-year period. Out of that group, 322 had lingual retainers bonded from canine-to-canine, 89 subjects had lingual retainers bonded between the lateral incisors, and 35 subjects had lingual bonded retainers between the 2 central incisors. The authors evaluated the debond or failure rate of these subjects.

An Overview of Fixed and Removable Orthodontic Retainers
Background and purpose: One of the main challenges in orthodontic treatment is relapse after treatment and return of the teeth to its original position. Therefore, retainers are an essential part of orthodontic treatment. Fixed and removable retainers are commonly used in orthodontic retention. They prevent relapse and require patientchr('39')s cooperation in using them. This review study aime...

The objective of this study was to compare glass fibre reinforced (GFR) with multistranded bonded orthodontic retainers in terms of success rate and periodontal implications. A 2 year parallel study was conducted of 184 patients scheduled to receive bonded retainers in the upper and lower anterior segments. In three centres, the patients (mean age 14 years; 90 males and 94 females) were sequent...

متن کاملClinical evaluation of bond failures and survival between mandibular canine-to-canine retainers made of flexible spiral wire and fiber-reinforced composite
OBJECTIVES The purpose of this longitudinal prospective randomized study was to evaluate the clinical reliability of two different types of postorthodontic treatment retainers: a silanised-treated glass fibers-reinforced resin composite (FRC) and a directly bonded multistranded stainless steel wire. The hypothesis of the study was to assess if significant differences are present between failure...
متن کاملA prospective clinical evaluation of mandibular lingual retainer survival.
Bonded retainers are considered reliable, independent of patient co-operation, and highly efficient. However, most studies regarding the survival of retainers are retrospective. The aims of this investigation were to prospectively evaluate the failure rate of bonded lingual retainers, the influence of direct or indirect bonding procedures on survival, and to determine the distribution of failur...
