dental hygienist Osaka dental university hospital, Osaka, Japan
Background: This is a case report of peri-implantitis treatment outcome as peri-implant bone defect recovery caused by infection control re-introduction based on re-establish confidence between patient and dental hygienist.
Case: The dropout patient is 60 years old female, first visit date was Feb, 2006, after complete the implant treatment, she dropout the implant maintenance for 9 years. She referred to the hospital in April, 2018 caused by pain and smell around implant. The diagnosis in oral condition was peri-implantitis, peri-implant mucositis, and chronic periodontitis as Stage 4, Grade A. Clinical procedures and outcomes: We discussed the cause of dropout was lack of understanding for implant maintenance, she understood the peri-implantitis can be treated by infection control based on daily plaque control. And sulcus bleeding index was evaluated by the patient such as no attached bleeding on tooth brush and inter dental brush. After 2 weeks, supra mucosal plaque control was achieved as no sulcus bleeding index. Subsequently, submucosal plaque control was performed by non-surgical therapy using carbon curette. Otherwise, no reacted site by non-surgical implant sites as 15,17,24,25 was performed by open flap debridement. After 1 year, all peri-implant sites demonstrated SBI(-), BOP(-), pocket reduction, and bone fill at bone defect area. And all periodontitis sites showed pocket reduction.
Conclusion: Infection control is very important to treat peri-implantitis and also periodontitis, and regular interval recall is necessary. For the sake of successful implant maintenance, it is most important for dental hygienist to establish good communication and re-establish confidence between patients.
