Abstract Background: Molar bands, essential for orthodontic anchorage, may negatively influence periodontal health. Custom bands are expected to provide better adaptation and supragingival positioning compared with standard bands. Objectives: The primary objective was to evaluate differences in bleeding on probing (BOP) between custom and standard bands at 6 and 12 months.. Secondary objectives included comparison of plaque control record (PCR) and probing depth (PPD). Methods: This retrospective clinical study analyzed 60 orthodontic patients treated between May 2023 and February 2025. Participants were divided into two cohorts: custom bands (n=30) and standard bands (n=30). PCR, BOP, and PPD were measured at baseline, 6 months, and 12 months. Data normality was tested with Shapiro–Wilk; intergroup comparisons used Mann–Whitney or t-test; intragroup changes were analyzed with Friedman/ANOVA as appropriate. Results: At 12 months, BOP increased by 28% in the Standard group versus 16% in the Custom group (between-group difference: –12%, 95% CI –18 to –6; p=0.01). PPD increased by 0.5 mm in the Standard group versus 0.2 mm in the Custom group (between-group difference: –0.3 mm, 95% CI –0.5 to –0.1; p=0.03). No significant differences were observed for PCR (p=0.47). Conclusions: Both band types negatively affected periodontal health over the 6- and 12-month follow-up periods, Custom bands were associated with reduced bleeding and probing depth. Customized design and supragingival placement may represent a preventive strategy during fixed orthodontic therapy.
Background: Le bande molari, fondamentali per l’ancoraggio ortodontico, possono influenzare negativamente la salute parodontale. Le bande customizzate sono progettate per garantire un migliore adattamento e un posizionamento prevalentemente sopragengivale rispetto alle bande standard. Obiettivi: L’obiettivo primario dello studio era valutare le differenze nel sanguinamento al sondaggio (Bleeding on Probing, BOP) tra bande customizzate e bande standard a 6 e 12 mesi. Gli obiettivi secondari includono il confronto del Plaque Control Record (PCR) e della profondità di sondaggio parodontale (Probing Pocket Depth, PPD). Metodi: Questo studio clinico retrospettivo ha analizzato 60 pazienti ortodontici trattati tra maggio 2023 e febbraio 2025. I partecipanti sono stati suddivisi in due gruppi: bande customizzate (n = 30) e bande standard (n = 30). PCR, BOP e PPD sono stati rilevati al baseline, a 6 mesi e a 12 mesi. La normalità dei dati è stata valutata mediante test di Shapiro–Wilk; i confronti intergruppo sono stati eseguiti con test di Mann–Whitney o t-test; le variazioni intragruppo sono state analizzate mediante test di Friedman o ANOVA, secondo appropriatezza. Risultati: A 12 mesi, il BOP è aumentato del 28% nel gruppo Standard rispetto al 16% nel gruppo Custom (differenza tra gruppi: –12%, IC 95% –18 a –6; p = 0,01). La PPD è aumentata di 0,5 mm nel gruppo Standard rispetto a 0,2 mm nel gruppo Custom (differenza tra gruppi: –0,3 mm, IC 95% –0,5 a –0,1; p = 0,03). Non sono state osservate differenze statisticamente significative per il PCR (p = 0,47). Conclusioni: Entrambi i tipi di bande hanno mostrato un impatto negativo sui parametri parodontali durante il follow-up a 6 e 12 mesi; tuttavia, le bande customizzate sono risultate associate a una riduzione del sanguinamento al sondaggio e della profondità di sondaggio. Il design personalizzato e il posizionamento sopragengivale potrebbero rappresentare una strategia preventiva efficace durante la terapia ortodontica fissa.
