Effects of Titanium Implant Combined with Nano-Indentation in the Vertical Control of Physiological Anchorage Spee’s Wire System Corrective Technology

Abstract

In the current research, there was, in the vertical control of physiological anchorage spee’s wire system (PASS) technology, an investigation on the role of titanium implant technology in combination with nano-indentation experiment the present research. The human jaw was selected as the sample to be cut vertically, by doing do, to obtain a test slice of about 2 mm through a cutting machine following the nano-indentation test. The slice was frozen and preserved in normal saline and taken out during the test. 40 outpatients who underwent orthodontic therapy were chosen as the research objects and rolled in a random manner into a control category and an category of observation. Then, mechanical biological therapy (MBT) correction was conducted for the outpatients from the control category and PASS correction therapy based on the nano-indentation experiment was for outpatients from the category of observation. Following therapy, the therapy conditions of these two categories were compared, showing that the load was a fixed value and the depth of the indentation was increasing. Under the action of external force, the periodontal ligament might undergo elastic deformation, changing with duration. Dentition alignment duration, ligation duration, and deligation duration were less for participants in the observation group compared to those in the control category (P less than 0.05). The inclination between the longitudinal plane of the top central incisor and the sella juncture root point plane (UI-SN angle), the spacing between both the top mandibular teeth margin and the nasal root juncture molar seat point (UI-NA distance), and the angle between the upper and lower central incisor tooth axis and the NA connection (UI-NA angle) were all significantly less pronounced in the category of observation than in the control category (P less than 0.05). However, the angle of upper and lower central incisor long axis (UI-LI angle) from the category of observation was hugely greater than that of the control category (P less than 0.05). The value of dental arch width in the category of observation was smaller significantly than the value of the control category (P less than 0.05), and the changes in dental arch width were larger than those in the control category (P less than 0.05). Besides, the measured values of X-ray projections of outpatients from the category of observation were higher at of the control category (P less than 0.05). In conclusion, nano-indentation experiment can accurately match the equipment required in the therapy. The application of titanium materials combined with the vertical control of PASS correction technology can effectively alleviate the clinical symptoms of outpatients so as to improve the therapy effect.
