Objective To observe the effect of digital impression technology in dental implant restoration. Methods A total of 88 patients undergoing dental implant restoration admitted to the Affiliated Stomatological Hospital of Suzhou Vocational Health College from January 2023 to May 2024 were included as the research subjects, and they were divided into the traditional group (n =44) and the digital group (n =44) according to different impression methods. The traditional group received traditional impression, and the digital group received digital impression. The dental implant restoration quality, impression comfort, occlusal force, masticatory efficiency, operation time, adverse reaction rate and satisfaction rate were compared between the two groups. Results The marginal adaptation, proximal contact adaptation and impression comfort of dental implant restoration in the digital group were higher than those in the traditional group (P <0.05). The occlusal force and masticatory efficiency of the digital group after restoration were higher than those in the traditional group (P <0.05). The impression time, adjustment time and total operation time of the digital group were shorter than those in the traditional group (P <0.05). The incidence of adverse reactions in the digital group (6.82%) was lower than that in the traditional group (25.00%) (P <0.05). The total satisfaction rate of the digital group (95.45%) was higher than that in the traditional group (77.27%) (P <0.05). Conclusion The application of digital impression technology in dental implant restoration demonstrates favorable advantages, including short chair time, convenient process, high restoration accuracy, few adverse reactions, and high patient comfort and satisfaction, which is worthy of clinical application.
