back to the referring dentist. Supragingival
professional tooth cleaning was performed
every week for 60 days and the patient was
followed up with every three months until
healing had occurred with no complications
or adverse events.
Clinical parameters such as mBI, mPlI,
PD and implant mobility (IM) were registered
at the 12-month follow-up visit, confirming
a state of peri-implant health (Fig. 21).
The results:
* Clinical parameters before and after
treatment are summarized in Table 1.
* The mBI, mPlI and PD values at
the follow-up visit were significantly
lower than those from baseline.
* IM remained unchanged.
* HBT was significantly higher at
re-entry surgery, compared with
baseline.
* VBD was significantly lower at
re-entry surgery, compared with
baseline.
The data indicates that after one year, the
treated implant could be considered healthy.
Conclusions
Bacterial biofilm accumulation around
dental implants is a significant problem,
leading to peri-implant diseases and implant
failure.
The most critical issue in regenerative
therapy of peri-implant vertical bone defects
is related to the possibility of obtaining a

predictable implant surface decontamination.
Though several methods have been described
so far, the literature does not clearly indicate
superiority of a specific decontamination
protocol. Cavitation occurring in the cooling
water around a dedicated ultrasonic tip can
be used as a novel solution to disrupt bacterial
biofilm without any surface damage.
Although clinical results with the
Piezoclean device are very promising, more
randomized, controlled clinical trials as well
as histological confirmation are needed to
corroborate the current preliminary data. n
