Orthodontic Retention

Abstract Background Orthodontic retention aims to maintain optimal teeth positions after active treatment. The stability is affected by numerous factors, including patients’ individual features, thus retention should be adjusted in the most optimal way. Bonding a retainer makes retention less dependent on patient’s compliance. Questions arise What wire or fiber splint type provides the best treatment stability? What materials should be used to bond the wire or fiber splint? Should be the bonding procedure be direct or indirect? The aim of the study is to assess and synthesize available controlled trials investigating failures of fixed retainers. Methods Literature searches of free text and MeSH terms were performed in Scopus, Web of Science, Embase and PubMed Central in order to find studies, referring to failures of fixed retention (12th February 2021). The keywords were: (“orthodontic retainers AND failure AND wire”). The framework of this systematic review according to PICO was: Population: orthodontic patients; Intervention: fixed orthodontic retainer bonding; Comparison: Different protocols of fixed orthodontic retention applied; Outcomes: failure rate, survival rate. Three different specific scales from the Cochrane Collaboration Handbook were used, according to each study type. Additionally, a meta-analysis was conducted to compare the effectiveness of retention using fiber reinforced composite and multistranded steel wire. Results The search identified 177 potential articles: 114 from PubMed, 41 from Scopus, 20 from Web of Science and 2 from Embase. After excluding studies inconsistent with selection criteria, 21 studies were included and subjected to qualitative analysis. The main outcome investigated was failure rate. This systematic review has some potential limitations due to the heterogeneity of design between included studies. Conclusions No retainer is proved to guarantee a perfect stability of dental alignment. The retainer should be bonded to all adherent teeth, preferably with additional use of bonding resin. No wire or fiber splint present superior characteristics concerning failure rate. Fiber reinforced composite retention is more sensitive to operator skills, and with imperfect bonding technique, failure rate is much higher. During the first 6 months after bonding retainer the patient should be under frequent control. The study protocol was registered in PROSPERO database with the number CRD42021233406.

BACKGROUND Premature loss of primary teeth requires orthodontic intervention to prevent the occurrence of malocclusions in the future. The most preferred way to maintain this space is by using space maintainers. Band and loop maintainers are the most commonly used fixed space maintainers. Despite being the most effective, it has several disadvantages. Hence, the objective of this review was to compare the efficiency between fiber reinforced composite (FRC) space maintainer and the conventional band & loop space maintainer. METHODS A systematic review was performed. Electronic and hand search retrieved 260 records, 246 were screened. The intervention and outcomes were assessed in the study included for systematic review. RESULTS Seven studies were included in this systematic review. These studies compared the fiber reinforced composite and the conventional band & loop and provided results about their clinical efficacy and patient satisfaction. CONCLUSIONS Despite being one of the gold standard appliances for space maintenance, the conventional band and loop space maintainers have multiple disadvantages. The major disadvantages included failure of the appliance due to cement loss and bending of the wire. Out of the 7 articles included in this study, 6 of the articles concluded that the FRC space maintainers are as effective as the conventional band and loop. FRC space maintainers proved to be time effective, more aesthetic, has better patient acceptance and is easier to fabricate. Hence, fiber reinforced composite space maintainers can be used as a more aesthetic and effective alternative to the conventional band and loop space maintainers if proper technique and protocol is followed.

Objective: The question of whether classic cast post-and-core (CPC) or fiber-reinforced composite resin posts (FRCP) are the best clinical decision has still not been fully solved. Materials and Methods: One hundred and sixty-two teeth were restored with FRCP, and 162 CPC restored teeth were included in this study with a matched-pair design. In a primary analysis, the survival rates after one year (primary endpoint) were compared. The additional analysis included an evaluation of tooth- and construction-specific variables and an illustration of the survival up to 60 months via Kaplan-Meier curves. Results: FRCP showed lower failure risk considering the definitive prosthetic restoration and tooth type compared to CPC restored teeth. In total, 17 failures were observed in the FRCP group and 35 failures in the CPC group. A 60-month survival rate of 79.3% for FRCP and 64.5% for CPC was observed. Teeth serving as abutments for telescopic dentures were more likely to be affected by failure compared to teeth restored with single crowns. Conclusion: Within the limitations of this study, the FRCP showed a lower failure risk compared to the CPC, considering the definitive prosthetic restoration and tooth type within the observation period.
