Abstract

Introduction: Development of implant dentistry is one of the major advances in the dental science. With the development of implants in this field, implantologists face the inevitable challenge of how to deal with problems associated with implants. Studies so far have focused on surgical and prosthetic techniques, although information on how to treat the disease is still deficient. The aim of this review study was to provide a general view of conditions around implants and therapeutic suggestions in this regard. Review Report: Following an electronic search in Medline and Embase, papers were collected up to the end of 2011 and since controlled clinical trials in this field were limited, no restrictions were imposed on paper type. The previous review articles and Meta-analyzes were also used. Results: In relation to implants with bone loss involving less than 50% of the implant length, accurate assessment of bone resorption is recommended. If bone loss is less than 2 mm, nonsurgical approaches similar to those of periimplant mucositis are used. If bone loss is greater than 2 mm but less than half the implant length, surgery is recommended and if there is more than 50% bone loss around the implant, implant removal is often recommended. Conclusion: With an increasing number of implants placed every year, periimplant conditions have become a challenge. The decision-making tree presented here represents guidance for clinicians on how to deal with implant complications. Future studies in this area are needed to confirm the protocols presented here.   Key words: Dental implant, Disease, Periimplantitis
