Abstract
Implant connects internal part of body to its external structure of body, and mainly supported by alveolar bone. When Implants are inserted to bone, it is needed osseointegration to retain structural integrity, so the important factor is sound bone around implant. Especially, implant doesn’t have periodontal ligament, stress distribution differs a lot depends on multiple forces outside. Furthermore implant tends to spread infection easily to inner tissue, and more bone resorption. The etiologic factors for resorption are (1) traumatic injury during surgery, (2) excessive load due to trauma from occlusion, (3) periimplantitis, (4) micro gap between abutment and prosthetics, (5) abutment mobility, (6) biological width, and (7) implant design. etc. Branemark implant system is known for excessive resorption of cervical surrounding bone. The character of that system has all factors mentioned above. Current implant design strengthens the bonding force between abutment and prosthetics, so that wants to reduce mobility and stress. Changing cervical implant design to reduce stress of surrounding bone, causes reduced implant stability or unfavorable biological width. so the key is stable cervical design doesn’t have negative factors. In this article, we attached a “wing” designed for implant cervical design, and saw the difference of stress distribution and changes in bone remodeling.
