Indagine sulle condizioni dei tessuti perimplantari e sulla stabilità dei tessuti perimplantari in impianti posizionati con simultaneo intervento additivo: analisi retrospettiva di follow-up su 3 anni di un impianto a livello osseo di recente sviluppo

Lo scopo della presente analisi retrospettiva è stato di valutare le condizioni dei tessuti perimplantari e documentare la stabilità dei tessuti perimplantari in impianti C-Tech posizionati simultaneamente con un intervento additivo GBR (Guided Bone Regeneration, rigenerazione ossea guidata).

È stato analizzato clinicamente e radiologicamente un totale di 47 impianti, posizionati simultaneamente con una procedura GBR (Guided Bone Regeneration, rigenerazione ossea guidata) con un materiale osseo sintetico sostitutivo in 20 pazienti, almeno 3 anni dopo il carico.

L’analisi di follow-up ha rivelato un tasso di sopravvivenza del 100% e tassi medio-bassi di profondità di sondaggio (2,7 mm) e BOP (indice di sanguinamento) (30%). Il PES (punteggio estetica rosa) medio era di 10,1 dal valore massimo di 14.
Non erano presenti difetti perimplantari manifesti, e la perdita ossea media è stata di 0,55 mm.

In conclusione, gli impianti inseriti in combinazione con una procedura GBR (Guided Bone Regeneration, rigenerazione ossea guidata) possono raggiungere risultati funzionalmente stabili ed esteticamente soddisfacenti a lungo termine per la sostituzione di denti mancanti in caso di atrofia della cresta alveolare.
