ABSTRACT
ObjeactTo study the stress distribution of angled dowe l crown in anterior maxillary teeth. Method:
A 3-dimensio nal finite element model (3-DFEM) of a maxillary central incisor with a dowel, a core and the supporting tissues was established.The stress in various angled d owel designs with a 150 N force applied along the long axis of the crown in a v ertical load on the incisal edge was mesured on the 3-DFEM and analyzed with AN SYS sorft ware.Results:
The maximum stress was found in la bical cervical zone of the cortical bone around the teeth,the compressive stress in labical and tensile stress in palatal respectively.Conclusion:
In anterior maxilla with angled dowel crown maximum stress is in the cervical zone of cortical bone,and the magnitude of stress increases with the i ncreace of the angulation of dowel crown.
