Prevalence of Peri-implant Diseases associated with a Rough-Surface Dental Implant System: 9 Years after Insertion
نویسندگان
چکیده
Introduction: The aim of this study was a retrospective clinical evaluation of the long-term prevalence of peri-implant diseases associated with a modern rough-surface dental implant system. Materials and methods: A total of 237 implants were inserted in 47 patients between 1994 and 2005. Peri-implant parameters (sulcus bleeding, pocket depth and bone loss) were evaluated at a mean of 9.1 years after insertion. Based on these parameters, cases were classified as healthy tissue, peri-implant mucositis and peri-implantitis. One-way analysis of variance was used to compare group parameters. Results: A total of 211 implants (89%) were healthy, 21 implants (9%) showed peri-implant mucositis and 5 (2%) showed peri-implantitis. Risk factors for peri-implant diseases were alcohol (p<0.001) and nicotine abuse (p<0.001) and irradiation (p<0.001). Conclusion: After a mean of 9.1 years, the TiOblast® dental implant showed a marginal rate of peri-implant disease. The calculated risk factors for development of peri-implant diseases are in accordance to previous studies.

Background and Aims: Although dental implants have become a successful and predictable ong-term treatment for patients, not all implant treatments are necessarily successful and pre-implant diseases are spreading. The aim of this study was to determine the prevalence of peri-implantitis in patients one year after prosthetic loading in Khorramabad in 2021. Materials and Methods: In this cross-s...
متن کاملMaintenance of Dental Implants: A Review
Objective: Successful bonding of a dental implant to bone, which was referred to as osseointegration by Branemark has been well documented. However, long-term prognosis of an implant depends on adequate maintenance and long-term care. An effective maintenance program is required to preserve the health of peri-implant tissues. Several techniques have been suggested for this purpose but it is n...
