REUSE OF THE INTRAOSSEOUS PART OF THE DENTAL IMPLANT (THE CLINICAL CASE)

Introduction. Replacement of a small included defect in the frontal area with a fixed structure based on the implant is the optimal solution. It is not always required to remove the intraosseous part of the implant if there is a fracture of the abutment due to mechanical injury on the background of metal fatigue after its prolonged use. First of all, the abutment’s stability and quality of osseointegration should be determined. After all, a well-integrated intraosseous part of the implant can be further used to fix the pin structure a metalceramic crown on it. The aim. Show the possibilities of reuse of the intraosseous part of the dental implant after fracture of the orthopedic structure together with the abutment in the area of 11 teeth. Materials and methods. Long-term observation of the functioning of the endoosal implant, made in 1995, in patient J., born in 1977. Careful examination of the stability of the intraosseous part of the implant after abruption of the abutment in 2015 in order to address the issue of its further use for the pin structure. Results and their discussion. The stability of the intraosseous part for further functioning has been established by its careful examinination. A wide canal with smooth walls was created in the abutment due to the impossibility of detaching the rest of the abutment from the intraosseous part. An artificial stump with a pin by laboratory method and a metal-ceramic crown were made according to the classical method. There was a pathological mobility of the implant, due to which it had to be removed together with the orthopedic structure in 2020. Thus, the period of use of the intraosseous part of the implant left after the abutment fracture was extended for another five years. Refusal of traumatic removal of the intraosseous part of the implant was based primarily on the need to preserve the volume and structure of bone tissue in the frontal area. Conclusion. There is no need to remove the remaining part of the fractured implant urgently if the intraosseous part has the close contact with the bone of the alveolar process of the upper jaw and can be used as a support for the pin structure. The broken abutment with an prosthetic structure can be replaced by an artificial stump with a metal-ceramic crown. The total period of use of the intraosseous implant immersed in the alveolar process of the upper jaw was twenty-five years. Delaying the removal of a well-integrated intraosseous part of the implant is a positive moment for the patient not only from a clinical but also from a financial point of view.
