    Abstract
  •   Objective  To explore the advantages of digital impression technology and its adaptability in clinical application following single tooth implantation assisted by a manipulator.  Methods  A total of 30 patients with single tooth loss were selected from the Department of Stomatology at the First Affiliated Hospital of Bengbu Medical University from February 2023 to September 2024. Three months after undergoing implant surgery, the patients were randomly divided into a digital printing module (n=15) and a traditional printing module (n=15) by random number table method. The clinical effects of the two impression techniques were evaluated by analyzing the impression operation time, visual analogue scale (VAS), and the clinical suitability of the restoration crown. Additionally, patients were categorized based on the position of dental implants into anterior teeth, premolar, and molar groups. This was done to compare the clinical work efficiency differences between two impression techniques across various restoration areas.  Results  Compared to traditional impression technology [23.15 (18.93, 28.00) min], digital impression technology saved more time [19.72 (13.00, 25.02) min], and the difference was statistically significant (U=49.000, P < 0.01). In terms of nausea/vomiting, comfort level and convenience of operation, digital impression technology received higher patient satisfaction (P < 0.05). A majority (83.33%, 25/30) of patients preferred the digital impression method. While both impression techniques could achieve satisfactory crown abutment relationships, the digital group had a significantly shorter occlusal adjustment time [10.17 (3.15, 16.72) min] compared to the traditional group [18.07 (9.17, 24.60)min, U=27.500, P < 0.01]. Furthermore, compared to premolars or molars, anterior teeth required longer impression time, yet the occlusal adjustment time was significantly reduced (P < 0.05).  Conclusion  For single implant assisted by manipulator, digital impression technology can effectively restore the spaces of missing tooth. However, digital impression technology requires less time for occlusal adjustment of implant-supported crowns, particularly in the anterior teeth area. Additionally, patient satisfaction with digital impression technology is higher than with traditional methods.
