ABSTRACT
BACKGROUND:
As the rapid development of oral implantation and restoration techniques, as wel as the increasing enlargement of indications, angulated abutments have been widely used. Posterior teeth region, as the weight-loading region of occlusion, can bear great force from the implants, the assessment of angulated abutments in posterior teeth region has clinical value.OBJECTIVE:
To evaluate the short-term clinical efficacy of angulated abutments on the implant denture in posterior teeth region.METHODS:
From January 2008 to January 2013, 114 patients with 175 ITI implants in the posterior teeth region were included in this study and they al underwent single-crown restoration. The involved patients were divided into angulated abutment group and straight abutment group. Periodontal probing depth, modified plaque index, modified sulcus bleeding index and peri-implant crestal bone loss in two groups were recorded at 6 months and 2 years after restoration. Cumulative survival rate of the implant denture was calculated by life-table analysis. RESULTS ANDCONCLUSION:
There was no significant difference in periodontal probing depth, modified plaque index, and modified sulcus bleeding index between two groups (P>0.05). The annual crestal bone loss showed no significant difference between two groups (P>0.05). Moreover, the 5-year cumulative survival rate with 15° and 20° abutments was 95.6%, and that with straight abutment was 96.4%. The angle of abutments has no correlation with peri-implant soft tissue and peri-implant crestal bone loss, implant restorations with 15° and 20° angulated abutments may be successful y used in the posterior region, whereas the long-term effects need further research.
