De Araujo Nobre et al reported a score for predicting prei-implant disease in a patient with dental implants. This can help to identify a patient who may benefit from more aggressive management. The authors are from the University of Lisbon, Malo Clinic (Lisbon) and University of Campinas (Sao Paulo).
Patient selection: dental implant
Parameters:
(1) history of periodontitis
(2) bone level located on the implant's middle third
(3) lack of prosthetic fit or non-optimal screw joint
(4) bleeding
(5) type of material used in the restoration
(6) plaque
(7) adjacent implants or teeth present
