Abstract: Summary：Magnetic attachment and extracoronal attachment are applied widely in clinic;however，to some degree， the scope of the application of either attachment is still limited. As we know that dentition defect with isolated residual root or residual crown is the complex but common clinical case， if we use either attachment to treat that case， the clinical effect， usually， is not satisfactory. Therefore， the combined application of magnetic attachment and extracoronal attachment in prosthodontics can not only show each attachment’s advantages but also make up for each other’s disadvantages， which， consequently， could get the best clinical effect.
