RESUMEN
Objective: The aim of this study is to discuss the non-surgical periodontal instrumentation, (which is necessary and irreplaceable) with the adjuctive use of diode laser (810nm), in the treatment of peri-implant infalmmation. Data are limited to a case report. Presentation of Case: After 12 years from implants insertion, which was carried out in 1992, a periodontally susceptible patient, shows signs of peri-implant inflammation (2004). Nowadays, after non-surgical periodontal laser-assisted therapy and 9 years of follow-up, implants shows no more signs of inflammation. Periodontal Therapy and Supportive Treatment are Made of Two Indispensable Phases: professional oral hygiene and home care instruction. During professional oral hygiene appointment, in addition to mechanical (dedicated ultrasonic inserts) and manual (titanium curette) non-surgical periodontal instrumentation, a diode laser in pulsed wave, at of 1Watt (2Watt the first appointment) for 20sec in duplicate at each site, was used. Professional treatment included also air polishing with glycine powder and application of CHX 0,5%gel. The patient was instructed in proper home care. Discussion and Conclusion: each treatment stage was carried out as required by the protocol and the patient has faithfully followed the oral hygiene instructions. Peri-implant clinical situation has remained fairly stable, showing normal periodontal parameters, more than 20 years from implants insertion. The present case shows how, traditional protocols of non-surgical periodontal therapy, in conjunction with the diode (810nm) laser, seem to be an effective alternative treatment modality in non-surgical treatment of peri-implantitis, in a periodontal susceptible patient. Obviously, data are limited the present case report and should be validated by further longitudinal clinical studies.after
