Abstract
Peri-implantitis is one of the most important biological complication of dental implants. It has inflammatory nature, proved association with plaque accumulation in peri-implant tissues, and can be progressive on background of several factors, like comorbidity factors and bad habits. The prophylaxis and different methods of treatment were discussed during last 30 years, and surgical and nonsurgical techniques have their foes, benefits, and disadvantages. In this article, we describe the case series of various nonsurgical treatments of peri-implantitis with the use of protocols based on the application of local antibiotics (doxycycline, lincomycin, and erythromycin), mechanical and chemical debridement of dental implant surface, and mini-invasive regenerative technique with injections of bovine collagen. All these three cases demonstrated good results with the maintenance of bone level and absence of clinical signs of inflammation for at least a year according to the X-ray imaging (bone defect volume) and clinic assessments (probing depth, bleeding or suppuration, mucosa color, and pain presence).
Highlights
In the absence of all these signs, the diagnosis can be provided according the combination of the following criteria: depth of probing not less than 6 mm, appearance of bleeding or suppuration during this measurement test, and the bone loss level with apical direction not less than 3 mm in comparison to coronal intraosseous part of dental implant [6,7,8]
The prevalence of peri-implantitis is higher than it was considered before: during the first 10 years after dental implantation, it varies from 1% to 47% according to a systematic review of Derks and Tomasi (2015)
We proposed the use of topical applications of 30% lincomycin hydrochloride (Lincomycin®, DalChemPharm, Khabarovsk, Russia) on the first day of treatment after professional oral hygiene maneuvers
Summary
Over the last 30 years, dental implants have become the most viable and effective treatment for partial and complete edentulous arches, providing effective masticatory function and esthetics.the spread of dental implants in the past decades have brought to light the importance of preventing, diagnosing, and treating peri-implant diseases, because of their important prevalence in the population, over time [1,2,3,4,5].Under peri-implantitis, we recognize plaque-associated pathological condition of peri-implant tissues, characterized by inflammatory process of mucosa and progressive bone loss near the dental implants, and can be defined by the identification of several signs such as bleeding or suppuration during careful probing and progressive of peri-implant bone loss beyond the crestal ridge due to initial bone remodeling. Over the last 30 years, dental implants have become the most viable and effective treatment for partial and complete edentulous arches, providing effective masticatory function and esthetics. In the absence of all these signs, the diagnosis can be provided according the combination of the following criteria: depth of probing not less than 6 mm, appearance of bleeding or suppuration during this measurement test, and the bone loss level with apical direction not less than 3 mm in comparison to coronal intraosseous part of dental implant [6,7,8]. The prevalence of peri-implantitis is higher than it was considered before: during the first 10 years after dental implantation, it varies from 1% to 47% according to a systematic review of Derks and Tomasi (2015).
