Abstract:
Objective The small-diameter titanium-zirconium implants were used to repair the missing posterior teeth.The status of soft and hard tissue around the implants and the possible mechanical complications were observed and the clinical efficacy was evaluated.Methods 20 patients (24 implants) who were treated with small-diameter SLActive titanium-zirconium soft-tissue level implants (diameter 3.3 mm) in the posterior teeth area were selected as observation groups.25 patients (30 implants) were treated with standard-diameter SLA titanium soft-tissue level implants (4.1 mm) in the posterior teeth region were selected as controls.We measured and documented the implant stability quotient (ISQ);6 months after implant treatment,we recorded implant marginal bone loss (MBL),modified plaque index (mPLI),modified sulcus bleeding index (mSBI) and probing depth (PD) and documented the possible mechanical complications.Results The ISQ value in the observation group maintained an upward trend within 12 weeks after the operation;the ISQ value in the control group was low at 4 weeks and then increased steadily.There was no significant difference in MBL,mPLI,mSBI and PD between the two groups after six months of ending treatment.No mechanical complications occurred in either group.Conclusions Small-diameter titaniumzirconium implants repairing the missing posterior teeth have a good soft and hard organizational status and short-term clinical efficacy.
