Long-term influence of fixed lingual retainers on the development of gingival recession: A retrospective, longitudinal cohort study

Abstract

Objective: To investigate the long-term influence of fixed lingual retainers on the development of mandibular gingival recession and to compare the prevalence with untreated individuals. Materials and Methods: The material consisted of 144 subjects: 96 orthodontically treated patients followed for 5 years after therapy and 48 untreated age-matched subjects. The treated patients were divided in two groups: one receiving a fixed mandibular retainer (n ¼ 48) and one receiving no form of retention in the mandible (n ¼ 48). The presence or absence of gingival recession and calculus accumulation were scored before treatment (T0), after debonding (T1), and 5 years after debonding (T5) for each tooth in the mandibular intercanine region using plaster models and intraoral photographs. The chi-square test, one-way ANOVA, and Cochran's Q test were used to evaluate inter-and intragroup differences. Results: The prevalence of patients with recession increased gradually and significantly throughout the observation periods in all groups, but the intergroup differences at T5 were not significant. Significantly more calculus accumulation was observed at T5 in the retainer group compared with the group without retainers. Conclusions: Long-term presence of fixed lingual retainers does not seem to increase the development of mandibular gingival recession, but does increase calculus accumulation.

Wann weist ein Patient ein erhöhtes Rezidiv-Risiko auf und ist dauerhafte festsitzende Retention vertretbar?

“…Interdentalhygiene benötigt mehr Zeit und Geschick. Studien haben gezeigt, dass es zu mehr Plaqueakkumulation an Lingualretainern bei allgemein eingeschränkter Mundhygiene kommt [27][28][29][30]. Bei ausreichender Mundhygiene sind festsitzende Retainer gut putzbar [28].…”

“…Es kommt jedoch nicht vermehrt zu Parodontopathien und Karies im Vergleich zu Patienten ohne Retainer [27]. Ebenso sind bukkale Rezessionen durch ein multifaktorielles Geschehen bedingt und nicht allein festsitzenden Retainern zuzuschreiben [30]. Oft wird ein Rückgang des Alveolarknochens durch dauerhafte Retention erwähnt.…”

Herbst appliance with skeletal anchorage versus dental anchorage in adolescents with Class II malocclusion: study protocol for a randomised controlled trial

“…In the presence of recession, a ‘yes’ will be marked. The photographs will be used to confirm [ 18 ] To evaluate root resorption, comparison between CBCT from the beginning and the end of the Herbst phase will be used for each lower incisor To explore young people’s experience of using the two types of Herbst appliance, the following methods will be used: Self-reported questionnaire about patient discomfort Semi-structured interviews …”

Effect of gingival biotype on orthodontic treatment-induced periodontal complications: A systematic review

“…3,4 However, orthodontic appliances might increase plaque accumulation and impede proper oral hygiene, which raise the possibility of making these treatments detrimental to periodontal tissues. [5][6][7][8][9] Lindhe and Seibert 10 used the term "periodontal biotype" to describe morphologic characteristics of the periodontium. In general, there are two types of gingival biotype: "thin scalloped" and "thick flat."…”
