    Abstract：ObjectiveTo investigate the lateral cap attachment at Kennedy Ⅱ dentition defect in the application results. Methods Kennedy Ⅱ dentition defect in adult patients with lateral cap attachment dentures steel prop 30, to observe the stability of attachment-retained dentures, aesthetics, comfort, pronunciation function, the ability to chew, abutments Zhou conditions underpinning fit with the alveolar ridge, the base tooth mobility.ResultsAfter 3~24 months of follow-up, good lateral steel prop cap attachment denture retention stability, can effectively chew, beautiful and comfortable. Abutment periodontal condition is good, underpinning the alveolar ridge fit the situation is good, no loose abutment cap. ConclusionLateral attachment is an ideal dentition defect retainers. ......
