新式奈米表面處理技術應用於人工牙根之電腦模擬分析

The aim of the present study was to investigate the osseointegration in the mandible with dental implants containing micro arc oxidized (MAO), and acid-etched (SLA) surface modifications. Three-dimensional (3-D) mandible models were reconstructed using computer tomography to simulate the electrosurgical procedure. The treated layer of dental implant is a very important factor in clinical application. Several studies have investigated finite element models for dental implants, but few have examined a model for devices with treated layers. Data indicated that the stress decreased significantly when implants with nanostructured MAO and SLA thin films were used. Moreover, SLA implant created a relatively small stress and decreased 8.49% compared with control groups. The present study reveals that the novel nanostructured thin film on dental substrates is an effective means of improving the performance of reducing excessive stress effect and uniformly distributing stress in the mandible. However, further tests in the animal model and clinical trial must be evaluated to confirm the effect and safety of promising findings in the implants.
