The present invention discloses a system for detecting irregular bone defects during dental implant osseointegration process and a control method thereof. The system comprises a detecting abutment, an ultrasonic driver, and a signal receiving and an analyzing device. When dental detection is performed, the detecting abutment is disposed on a substrate holder of a dental implant. The ultrasonic driver configures the piezoelectric transducers disposed on the detecting abutment to produce ultrasonic wave and transmits the ultrasonic wave to the contact surface between the dental implant and the alveolus bone. The piezoelectric transducers can receive the reflected wave caused by the each portion of the contact surface reflecting the ultrasonic wave and transform the reflected wave into time domain voltage signal. The signal receiving and analyzing device receives the time domain voltage signal to determine the depth, the severity and the location of the irregular bone defects of the contact surface.本發明係揭露一種牙科植體骨整合期之骨缺損檢測系統及其控制方法。此系統包含檢測承座、超音波驅動器及訊號接收分析器。當檢測時,將檢測承座被設置於牙科植體之基台上,再透過超音波驅動器驅動設置於檢測承座上之複數個壓電換能器產生超音波,並傳遞至牙科植體與齒槽骨之接合面,複數個壓電換能器能接收由牙科植體與齒槽骨之接合面各部位反射超音波所產生之反射波,並將反射波轉換為電壓時域訊號,再回傳至訊號接收分析器,以測定牙科植體與齒槽骨之接合面各部位之骨缺損深度、嚴重程度及方位。1‧‧‧骨缺損檢測系統11‧‧‧超音波驅動器12‧‧‧檢測承座121‧‧‧超音波122‧‧‧電壓時域訊號13‧‧‧訊號接收分析器14‧‧‧齒槽骨及牙科植體之接合面141‧‧‧反射波
