Impression techniques in fixed partial denture. A requisite for accurate prosthesis fabrication

      Аннотация: An important factor that ensures long-term success in fixed dental prosthesis is a precise record and reproduction of the prepared teeth, soft tissues and adjacent structures. A precise impression is a prime requisite for such an prosthesis. Excellent impressions require accurate and stable impression materials, time and a thorough working knowledge of all the aspects of the concepts involved. If the clinician continues to have ill-fitting restorations, it may not only be due to inadequacy of the impression materials, but rather due to unacceptable clinical procedures. Digital devices are here to stay and will only increase in use in the near future.Technology is rapidly growing and equipment is becoming more affordable.Impression wands and units are becoming smaller, more user friendly, and capable of capturing color images at increasing speeds. Most systems do not require powder to capture intraoral images and the open-platform interface can be exported to integrate with other imaging modalities, like cone-beam computed tomography (CBCT), facial laser scans, or 3D photographic images.The applications for this technology are voluminous and it can be used in Prosthodontics.
