Abstract

Background: It is more difficult to achieve optimal initial stability in the positions of the newly extracted posterior teeth because of the alveolar bone morphology as well as the inability to expand the bone drilling area to place the implant due to the related problems. Adjacent anatomical structure assessment of implant stability after immediate implant treatment is an important criterion for final restoration. Objective: To evaluate the stability of the implant after immediate implant treatment to restore the mandibular first molar. Materials and methods: Patients over 18 years old who came to the hospital of Can Tho University of Medicine and Pharmacy with an indication of tooth extraction for immediate implantation of the mandibular first molar. Patients with teeth or roots of the mandibular first molars indicated for extraction; Crest is equivalent to adjacent teeth; The outer or inner alveolar wall is intact; There is no inflammation with purulent discharge right after tooth extraction; The adjacent soft tissue does not have inflammatory granulomatous tissue or cellulitis. Sampling method: convenient sampling selected all patients who came to the Department of Odonto-Stomatology, Can Tho University of Medicine and Pharmacy from April 2020 to December 2020. Results: D1 bone density accounted for 2.7%, D2 and D3 bone density had the same ratio (45.9%), in which type D2 was mainly in men and D3 in women. Immediately after surgery, the rate of good ISQ value (>70) was 5.4%, while the rate of implant with ISQ value <60 accounted for 67.6%. After 6 months, the implant rate was stable well. increased from 5.4% to 21.6%, the percentage also increased from 27% to 78.4% and there were no implants with poor stability. Conclusion: placing a single instant implant in the socket of the freshly extracted molar region gives positive results in terms of implant stability provided that strict selection criteria are followed.
