Abstract:

BACKGROUND: The peri-implant bone absorption is closely related to the repair effect.
OBJECTIVE: To compare the effects of three kinds of dental implant systems on the peri-implant bone absorption.
METHODS: 116 patients who underwent the dental implant systems were collected, including 46 cases with 3I implant system, 40 cases with ITI implant system and 30 cases with BLB implant system. The peri-implant bone absorption, sulcus bleeding index and periodontal probing depth of three groups were detected at 1, 3, 6, 9 and 12 months after implantation, respectively.
RESULTS AND CONCLUSION: The peri-implant bone absorption of three groups within 1 year after implantation was in a rise, and the bone absorption of BLB group was significantly higher than that of ITI and 3I groups at 3 and 12 months after implantation (P < 0.05). Compared with the natural teeth, the gingival sulcus bleeding index of three groups were all increased at different time points after implantation; the gingival sulcus bleeding index of BLB group was significantly higher than that of natural teeth at 6 months after implantation (P < 0.05); the gingival sulcus bleeding index of three groups were significantly higher than that of natural teeth at 9 months after implantation (P < 0.05). The periodontal probing depth of three groups showed an ascending trend at 6 months after implantation; the periodontal probing depth of three groups was higher than that of natural teeth at different time points after implantation, which exhibited significant differences at 6 and 9 months after implantation (P < 0.05). In conclusion, three kinds of dental implant systems exhibit differet effects on the peri-implant bone absorption, but all achieve excellent clinical efficacies.
