Prosthetic design and indication on separated posterior residual root

Objective: In order to explore the preservation of separated posterior root, separated residual root caseswere retrospective analysis and the prosthetic design and their indications were summarized. Methods: 35 separatedresidual roots in 34 patients were treated with post and core crown or overdenture. Treatment were planed based on thestate of residual root, situation of missing teeth, requirements of patient and his economic state. Results: The separatedresidual root can be restored with prosthesis satisfied with proper prosthetic design. After 2 years of treatment, the prosthesisworks well and the patients were satisfied. Conclusion: Even separated root can be preserved after reasonable design andtreatment. The optional prosthetic design include post and core supported crown and overdenture.
