Abstract
Objective: To analyse marginal bone level changes at implants placed using high-speed drilling (800 rpm) with irrigation versus low-speed drilling (150 rpm) without irrigation. Peri-implant soft-tissue parameters were assessed and the influence of bone density and vertical dimensions of supracrestal soft tissue on marginal bone level changes was evaluated.
Material and methods: Patients with a single posterior edentulous area were included in a randomized parallel single-blinded clinical trial. The study groups were: high-speed drilling with irrigation (CG:control group) and low-speed drilling without irrigation (TG:test group). Marginal bone level changes were measured using parallelized periapical radiographs during 12-months. Probing depth, bleeding on probing, plaque index, buccal keratinized mucosa, suppuration and recession were measured. The mean total bone density was evaluated in Hounsfield Units. Mann-Whitney U-test for non-parametric variables and t-test for parametric variables were employed.
Results: A total of 66 patients were included (33 per group). The implant success rate was 100% for both groups according to Misch classification. No statistically significant differences were found regarding marginal bone loss (CG: -0.03 (0.17); TG: -0.01 (0.05)), bone remodeling (CG: 0.81 (0.64); TG: 0.86 (0.54)), or peri-implant soft tissue parameters (p > 0.05). Bone density showed no significant correlation with the peri-implant bone and soft-tissue changes. The vertical supracrestal soft tissue was inversely correlated to peri-implant bone remodeling.
Conclusions: Within the limits, high-speed drilling with irrigation and low-speed drilling without irrigation had no statistically significant influence on the peri-implant marginal bone and soft tissue changes during 12 months of follow-up. These variables were not significantly influenced by bone density.
期刊介绍：
Clinical Oral Implants Research conveys scientific progress in the field of implant dentistry and its related areas to clinicians, teachers and researchers concerned with the application of this information for the benefit of patients in need of oral implants. The journal addresses itself to clinicians, general practitioners, periodontists, oral and maxillofacial surgeons and prosthodontists, as well as to teachers, academicians and scholars involved in the education of professionals and in the scientific promotion of the field of implant dentistry.
