In vitro comparison of the efficacy of two fractured implant-prosthesis screw extraction methods: Conventional versus mechanical

ConclusionsMechanical extraction is more effective for extracting fractured implant-prosthetic screws, showing a higher probability of extraction than the conventional method. Prosthetic fixing screws with a smooth shaft and threaded apical area are the easiest to extract.
