Abstract

Replacement of extracted root with immediate dental implant has better prognosis as compared to conventional procedures. In this regard, Expandable Micro-motor Bur (EMB) was developed to introduce a new procedure for least invasive surgery upon extraction of residual broken root and prompt replacement with dental implant. To extract broken roots, generally invasive approaches as open window surgeries or mucoperiosteal flap and/or removal of buccal bone are performed. Integrity of the socket is a critical criterion for a proper implant osseo-integration. Accordingly, least invasive removal of residual root should be performed to keep the socket integrity. EMB is a new dental instrument designed for immediate dental implants upon removal of broken teeth roots that cannot be extracted by the routine closed methods while it maintains the integrity of surrounding hard tissue which common instrumentations cannot afford to accomplish. The advantages of this innovative procedure are: (1) No need for mucoperiosteal flap, hence preservation of soft tissue, (2) no need for osteotomy, hence retention of buccal bone, (3) reduced invasion to surrounding anatomical structures and (4) enhancement of perfect post operative dental implant osseointegration.
