Introduction: The impression is a key stage in the success of the prosthetic process. Taking an impression remains the most difficult and delicate phase in the prosthetic chain. The aim of this study was to assess the attitude and knowledge of dental surgeons regarding impression taking in dental practices in Burkina Faso.
Materials and Methods: This was a descriptive cross-sectional study carried out in the city of Ouagadougou. A self-administered questionnaire was distributed to all dentists registered with the National Order of Dentists of Burkina Faso. The study included all dentists practising fixed prostheses who agreed to participate in the survey.
Results: Impressions without unitary guidance are the most commonly used (68.29%) in dental practices, and double-mixing (67.50%) is the most popular technique for taking impressions, whatever the type of impression. About a third of the dentists (29.28%) said that the dental technicians were always satisfied with the quality of their impressions, and more thanhalf of them (56.12%) said that they provided additional information to the dental technician when processing the impressions.The main reasons for repeat impressions were poorly made prostheses (34.15%) and difficulties in processing the impression by the dental technician (34.15%).
Conclusion: The quality of the impression depends on its clinical application. It is important to use a technique that is appropriate and well mastered for each clinical situation. Both in the practice and in the laboratory, a rigorous protocol must be followed to ensure that the impression and master model give reliable results.
