Abstract
One of the most important factor in implant therapy when performed as one option of restorative treatment to reconstruct edentulous dentition is the placement position. Prosthetic driven implant is not always possible, but I am trying to consider based on both top-down and bottom-up concepts at the time of examination and diagnosis.We are willing to perform treatment just following the plan that is made before onset of the treatment. However, as the treatment scale gets larger, more the uncertain factors increase. So we have to deal with unexpected incident that requires higher level of clinical skill.When performing comprehensive treatment that requires restorative treatment for multiple teeth, accurate provisional restoration is crucial because it provide us information before making definitive restoration. Present report shows a case that was suffered with moderate to severe periodontitis and that was treated by comprehensive treatment accompanied with implant prosthesis on edentulous area.
