Indications and methods of removing dental implants

Abstract

Aim: The aim of this research is to make a comparative interpretation of implant removals in the last 3½ years in the Department of Community Dentistry. Materials and methods: In the last 3½ years, 27 patients’ 46 implants were removed in the Department of Community Dentistry. The applied data were obtained by X-rays, medical charts, and patient management program, called FOGÁSZ, found in the Department of Community Dentistry. Data were evaluated with Microsoft Excel software. Results: The average age was 63.7 years; 96.3% of the patients were aged 50 or over; 63.9% of the concerned indi-viduals’ inserted implants were removed. Among maxilla and mandible, there are equal proportions of removed implant’s location partition; 22.7% of the patients lost their implants within 6 months from surgery. The removed implants were possessed 5.5 years long on average; 40.7% of the patients commanded fixed prosthesis-supported implant and teeth, and this was the most common prosthesis type. The prevalence of peri-implantitis around removed implants was 71.7%. Out of the partly edentulous patients, horizontal bone resorption was discernible in 47.6%; 15.2% of the removals were recommended because of inflammation before osseointegration. Conclusion: Fixed prostheses anchored at the same time to tooth and implant may cause implant loss, because biomechanical aspects of anchoring behave differently in the bone. Lack of peri-implantitis is a key factor in the success of implants. Peri o-dontitis could also promote the development of peri-implantitis. Clinical significance: Avoid planning prostheses anchored at the same time to tooth and implant. Sufficient oral hygiene is essential for the prevention of inflammation. Patients with peri-odontitis should be cured of inflammation before implantation. Important factor for osseointegration is the inflammation-free healing.
