Abstract

Abstract:

Objective To compare the clinical effects of ICam4D photogrammetry technology combined with intraoral scanning technology, traditional splint impression technology and traditional window impression technology in full dentition oral implant fixed prosthodontics. Methods A total of 46 cases of dentition, including 14 patients with complete dentition and 18 patients with single-jaw dentition, who had completed implant surgery and needed final restoration, were divided into three groups: the ICam4D group (Group A), the splint group (Group B), and the window group (Group C). Group A included 16 cases, in which ICam4D photogrammetry technology combined with intraoral scanning technology was used to take impressions. Group B included 15 cases, in which traditional splint technology was used to take impressions. Group C included 15 cases, in which only window impression rods were used for impression taking without splints. The marginal adaptation of the prosthesis, impression-taking comfort, time consumption, satisfaction with the restoration, and patient follow-up observations were compared among the three groups to evaluate the clinical effect of ICam4D photogrammetry technology combined with intraoral scanning technology in oral implant fixed prosthodontics. Results There was no statistically significant difference in the marginal adaptation of the prosthesis. The impression-taking comfort scores were: Group A (95.77±2.30), Group B (60.02±7.56), and Group C (71.92 ± 6.55). There were statistically significant differences among the three groups(P<0.001). The time consumption was: Group A (16.53±3.24)min, Group B (59.38±10.74)min, and Group C (25.46±5.63)min. There was a statistically significant difference(P<0.001). There was no statistically significant difference in the satisfaction with the restoration. Conclusion ICam4D photogrammetry technology combined with intraoral scanning technology is more time-efficient, provides higher patient comfort, and has better marginal adaptation of the prosthesis in oral implant fixed prosthodontics. It is recommended for clinical promotion.
