Abstract:
BACKGROUND:There are some controversies on the choice of immediate or delayed weight-bearing schemes of implants.
OBJECTIVE: To explore the weight bearing scheme for Bego implants based on implant stability quotient (ISQ) measured by Osstel, and to analyze the factors which influence implants’ stability.
METHODS:Seventy-four single Bego implants with ISQ≥ 50 in 62 patients were selected and randomly
divided into test group (36 single Bego implants in 31 patients) and control group (38 single Bego implants in 31 patients). Patients in the test group were given immediate loading, and patients in control group were given
delayed loading. Two groups’ ISQ of Bego implants after loading (1, 2, 3, 4, 6, 8 and 12 weeks) were compared, and factors which influence implants’ stability were analyzed.
RESULTS AND CONCLUSION:The lowest ISQ for immediate loading of the test group appeared in 2-3 weeks after loading, and that of the control group appeared in 3-4 weeks. There was no statistical difference between two groups on ISQ of Bego implants after bearing (1, 2, 3, 4, 6, 8 and 12 weeks) (P > 0.05). Multiple regression analysis showed that the factors including age, types of osseous substance and implant length were positively related with stability of Bego implants, yet oral hygiene was negatively related with stability of Bego implants. Immediate loading and delayed loading have similar stability to single Bego implants with ISQ≥ 50 measured by Osstel, so individualized weight bearing scheme may be selected according to patient’s own condition under the guidance of Osstel, further to improve implants’ success rate after loading.
