The use of short dental implants in rigid fixed bridge for multiple missing teeth:a 2-year follow-up visit / 中国组织工程研究

ABSTRACT

BACKGROUND: Short dental implants have been widely used in the posterior area when one tooth loses. How effective is it when we use the short implants in the rigid fixed bridge for the multiple teeth lost area?OBJECTIVE: To observe the clinical effect of short dental implants used in the rigid fixed bridge.METHODS: Forty-three patients with multiple missing teeth were enrolled and underwent the rigid fixed bridge supported by short dental implants, including 26 males and 17 females, with an age range of 44-67 years. After 2 years of dental implantation, the success rate of dental implants, amount of alveolar bone loss and dental implant-related complication were followed up.RESULTS AND CONCLUSION: A total of 92 short dental implants, 6-8 mm in length, were implanted,including 44 in the maxilla and 48 in the mandible. There were two cases of peri-implantitis and the success rate of implants was 97.8%. There was no significant difference in the amount of alveolar bone loss between the 8 mm, 7 mm and 6 mm length implants as well as between the C/I ≤ 1, 1 2 groups at 1-2 years after implantation. There were four cases of central screw loose and one case of porcelain fracture after restoration. To conclude, the clinical use of short dental implants in the rigid fixed bridge has achieved good outcomes during the short period, but long-term observation is needed.
