Intraoral scanning, CBCT, and surface electromyography combination: efficiency analysis of proposed diagnostic “Trident” algorithm during complex dental rehabilitation

Abstract

To evaluate the efficiency of dental treatment supported by the complex diagnostic algorithm consisting of digital scanning, CBCT, and surface electromyography procedures (“TRIDENT” algorithm) considering clinically objective and patient-oriented subjective criteria. The study cohort was formed out of 47 patients, who underwent implant placement and rehabilitation with the use of implant-supported fixed dental prosthetics. Initial intraoral scanning was provided by the Medit I500 device (MEDIT corp., Seoul, Korea), while CBCT-scanning was held on Planmeca ProMax® 3D Classic (PLANMECA OY, Helsinki, Finland). Dental occlusion analysis and control over muscle adaptation were held via the Teethan device (Teethan S.p.A., Milan, Italy). OHIP-EDENT questionnaire and Oral Satisfaction Scale were used to assess the improvements of patient-oriented subjective criteria. Treatment protocol provided with the complex diagnostic “TRIDENT” algorithm supported superior time efficiency of treatment (p < 0.05), and statistically significant improvements of several domains within OHIP-EDENT (p < 0.05), OSS values (p < 0.05) and patient adaptation criterion (p < 0.05) at 1, 2, 3, 4, 5, and 6 first weeks of ongoing monitoring. Bone level changes, implant success, and implant survival parameters after 1 year of monitoring have not demonstrated statistically significant deviations as compared to those registered among patients rehabilitated by classical implant placement protocols (p > 0,05). Dental implant treatment protocol with further prosthetic rehabilitation supported by the complex diagnostic “TRIDENT” algorithm demonstrated higher patient-oriented subjective efficiency up to the timepoint of 6 weeks of monitoring after initial prosthetics fixation.
