简要总结
compare CAD/CAM implant supported screw-retained metal frameworks based on actual versus screw-mented ones based on virtual implant position regarding marginal bone changes.
详细描述
patients with at least three missing teeth will be recruited and randomly assigned into two parallel groups. both groups will receive three implants based on planned implant positions and then one group will receive screw retained CAD CAM restoration with conventional impression technique while the second group will receive screw-mented CAD CAM restoration based on planned implant positions.
