The study aimed to evaluate the quality of conventional dental implant impressions submitted to a sample of dental laboratories in Sana\u2019a City, as well as assess dentists\u2019 knowledge, attitudes, and clinical practices regarding dental implant impression techniques.<\/p>\n

The study produced several key findings:<\/p>\n

    \n
  • 95% of the evaluated impressions contained at least one detectable defect.<\/li>\n
  • Condensation silicone was the most commonly used impression material, while prefabricated plastic impression trays were the most commonly used type of tray.<\/li>\n
  • The rate of critical errors at the finish-line area reached 87%, with impressions taken using the abutment-level technique showing the highest error rates.<\/li>\n
  • 66% of the participating dentists reported being unaware of specific techniques for taking dental implant impressions.<\/li>\n
  • Practitioners who were aware of advanced techniques showed a preference for Polyvinyl Siloxane (PVS) and the open-tray technique.<\/li>\n<\/ul>\n

    The study revealed a notable gap in dentists\u2019 awareness and in the standardization of clinical protocols for dental implant impression procedures.<\/p>\n

    The study recommended strengthening educational and training programs for dentists in dental implant impression techniques, implementing stricter quality-control measures in implant-supported prosthodontics, conducting further studies involving larger and more diverse samples to assess the quality of dental implant impressions and the factors affecting them, and standardizing clinical protocols for dental implant impression techniques and materials.<\/p>\n

    The defense session was attended by a number of academics, researchers, students, and interested participants, as well as the researcher\u2019s colleagues and family members.<\/p>\n
