Long-Term Impact of 1-mm Versus 3-mm Definitive Abutments on Marginal Bone Loss and Peri-Implant Disease: A 7-Year Randomised Clinical Trial
Aim
To evaluate bone level changes in implants with 1-mm- or 3-mm-high abutments over a 7-year period and to investigate the role of abutment height upon peri-implant status.
Materials and Methods
Two-piece implants were placed 1.5 mm subcrestally with either 1-mm (control) or 3-mm (test) high definitive abutments. Marginal bone level change from the first to seventh year was the primary outcome. Peri-implant status and other patient and peri-implant clinical variables (smoking, peri-implant maintenance therapy compliance, interproximal hygiene, vertical soft tissue thickness and keratinised mucosa width) were also assessed.
Results
After 7 years, 37 subjects (63 implants) were analysed: 17 subjects with 32 implants in the 1-mm abutment group, and 20 subjects with 31 implants in the 3-mm abutment group. Significant differences in marginal bone level changes were observed at 7 years. The 3-mm abutment group showed smaller changes compared to the 1-mm abutment group at mesial sites (−0.27 ± 1.32 mm vs. −0.42 ± 0.50 mm, respectively) and distal sites (−0.33 ± 1.39 mm vs. −0.35 ± 0.38 mm), with both differences being statistically significant (p < 0.001). In the control group, 18 implants (54.6%) presented peri-implant mucositis and 6 implants (18.2%) showed peri-implantitis. In the test group, 23 implants (74.2%) presented peri-implant mucositis and 1 implant (3.2%) showed peri-implantitis. No statistically significant differences were found (p = 0.158).
Conclusions
Subcrestally inserted implants with 3-mm definitive abutments experienced minimal bone loss over long-term follow-up compared to 1-mm abutments. However, since the differences were not statistically significant, no conclusions could be drawn on the protective effect against peri-implantitis.
期刊介绍：
Journal of Clinical Periodontology was founded by the British, Dutch, French, German, Scandinavian, and Swiss Societies of Periodontology.
The aim of the Journal of Clinical Periodontology is to provide the platform for exchange of scientific and clinical progress in the field of Periodontology and allied disciplines, and to do so at the highest possible level. The Journal also aims to facilitate the application of new scientific knowledge to the daily practice of the concerned disciplines and addresses both practicing clinicians and academics. The Journal is the official publication of the European Federation of Periodontology but wishes to retain its international scope.
The Journal publishes original contributions of high scientific merit in the fields of periodontology and implant dentistry. Its scope encompasses the physiology and pathology of the periodontium, the tissue integration of dental implants, the biology and the modulation of periodontal and alveolar bone healing and regeneration, diagnosis, epidemiology, prevention and therapy of periodontal disease, the clinical aspects of tooth replacement with dental implants, and the comprehensive rehabilitation of the periodontal patient. Review articles by experts on new developments in basic and applied periodontal science and associated dental disciplines, advances in periodontal or implant techniques and procedures, and case reports which illustrate important new information are also welcome.
