Dental implants are used for the reconstruction of missing teeth. Although they have high success rates, failures still occur. The difficult aspect to control is the interface between the implant and the bone into which it is inserted. Traditionally, titanium and its alloys have been used as implant materials, but more recently, the use of polymeric materials such as PEEK (Polyether Ether Ketone) has been proposed. This work proposes the use of the Acoustic Emission technique to monitor the primary stability of the bone-dental implant interface and, fundamentally, to compare the signals obtained when primary stability is lost. To achieve this objective, various implants were first inserted into a maxilla made of synthetic material; and then, the primary stability of the interface of said synthetic material with each implant was verified using the Acoustic Emission technique, applying a compressive load to the implant. The tests carried out highlighted the enormous advantages of using Acoustic Emission, since it allows the detection of poor bone-dental implant integration.
