Scanbody VS Analog Impression

Scanbodies and analog impressions are two different methods of capturing the position and orientation of dental implants for restorative purposes. Here’s a comparison between scanbodies and analog impressions:


  1. Digital Workflow: Scanbodies are used in conjunction with digital scanning technology, such as intraoral scanners or laboratory scanners. They facilitate the capture of digital impressions, which are then processed in computer-aided design (CAD) software for treatment planning and restoration fabrication.
  2. Accuracy: Scanbodies provide highly accurate and detailed digital representations of the implant site. They allow for precise measurement and visualization of the implant position, angulation, and surrounding structures, resulting in accurate restorations.
  3. Efficiency: Digital scanning with scanbodies is generally faster and more efficient than traditional analog impressions. It eliminates the need for physical impression materials, trays, and associated setting times. The digital workflow also enables seamless communication between the clinician and dental laboratory, reducing potential errors and delays.
  4. Patient Comfort: Scanbodies offer a more comfortable experience for patients compared to traditional analog impressions. They minimize the need for bulky impression materials, trays, and potential gagging sensations, resulting in a more pleasant and efficient clinical visit.

Analog Impressions:

  1. Traditional Approach: Analog impressions involve the use of impression materials (such as alginate or polyvinyl siloxane) and trays to create physical molds of the implant site. These molds are then used to produce stone or plaster models for treatment planning and restoration fabrication.
  2. Technique Sensitivity: Analog impressions require precise technique and attention to detail to ensure accurate reproduction of the implant site. It relies on the skill of the clinician in achieving proper tray placement, material consistency, and adequate tissue displacement.
  3. Material Selection: The choice of impression material can affect the accuracy and dimensional stability of analog impressions. Clinicians must select appropriate materials that provide good detail reproduction and dimensional accuracy for implant restorations.
  4. Laboratory Workflow: Analog impressions require physical transportation to the dental laboratory, where the stone or plaster models are poured, trimmed, and used for restorative fabrication. This process introduces additional time and potential errors associated with transportation and model pouring.

While analog impressions have been a long-standing method in dentistry, digital scanning with scanbodies has gained popularity due to its accuracy, efficiency, and patient comfort. The digital workflow enables streamlined communication, precise treatment planning, and efficient fabrication of restorations. However, the choice between scanbodies and analog impressions may depend on factors such as the clinician’s preference, the complexity of the case, availability of digital scanning technology, and the specific requirements of the patient and treatment plan.
