2_201318 Il provvisorio viene avvitato nella stessa gior- nata (Figg. 17-18). Dopo due mesi, a guarigione dei tessuti avvenuta, il provvisorio viene svitato per la presa dell’impronta definitiva (Figg. 19-20). Si utilizzano due monconi e, eseguita la pro- va metalli, si passa alla cementazione del manu- fatto definitivo (Figg. 21-25). Il controllo a un anno evidenzia l’ulteriore ri- modellamento positivo dei tessuti gengivali con chiusura degli spazi interdentali (Fig. 26). L’esame radiografico a due anni evidenzia un ottimo mantenimento del tessuto osseo crestale perimplantare (Fig. 27). Ringraziamenti: si ringraziano, per la parte protesica la dott.ssa Tiziana Rossi, e l’odt Luca Castellini per la parte odontotecnica. 1. Götz W, Gedrange T, Bourauel C, Hasan I. Biomed Tech (Berl).
