ABSTRACT
OBJECTIVES:
This study aimed to evaluate the application of digital impression and resin model technology in removable partial dentures (RPD) for Kennedy classâ andâ ¡dentition defects.METHODS:
Patients with Kennedy classâ orâ ¡dental defect were selected and grouped in accordance with the following denture production processes digital impression/resin model/cast cobalt-chromium alloy framework group (group A), digital impression/resin model/laser printed titanium framework group (group B), alginate impression/plaster model/cast cobalt-chromium alloy framework group (group C), and alginate impression/plaster model/laser printed titanium framework group (group D), with 40 cases in each group. The final RPD was examined in place in the mouth, and the evaluation indicators included the retention force of clamp ring, the tightness of connector and base, and the accuracy of occlusion. The evaluation scores of each index were used for analysis on the Kruskal-Wallis rank-sum test.RESULTS:
No statistically significant difference in the score of each index was found among the four groups in RPD.CONCLUSIONS:
The cast cobalt-chromium alloy and laser-printed titanium framework RPD using digital impression and resin model can meet the clinical restoration requirements of patients with Kennedy classâ andâ ¡dentition defects.Palabras clave
