Objective Assessment of Implants Stability placed in Fresh Extraction Socket using Periotest Device

Abstract

Objective: To present our experience of using periotest (PT) device for measuring implant stability in immediate implants placed in fresh extraction sockets.Materials and methods: We used a PT device to measure for 10 implants placed in 10 patients over a period of 18 months. All the implants were placed immediately after extraction. The minimum follow-up period was 6 months with PT readings taken at 4th, 5th and 6th months (stage I) and after restoration at 7th, 8th and 9th months.Results: Negative values are generally considered good. This means the implant is well osseointegrated and can be loaded. The PT values for the maxillary tooth were lower than those for the mandibular tooth. A stable mandibular implant presents PT value readings between �2 and +2. A stable maxillary implant presents PT value reading between �4 and �2.Conclusion: PT enables us to assess osseointegration noninvasively and objectively in any situation. PT helps us to optimize our decision whether or not an implant is ready for functional loading.
