Objective To evaluate in vitro the quality of dental implant biopsies collected using trephines or a sonic instrument. Method Sixty implants, 4 mm long and 2.4 mm in diameter, were installed in twelve fresh bovine ribs. Biopsies were collected after using three different methods for retrieval, 20 biopsies representing each group: (A) A trephine used concentrically; (B) a trephine used eccentrically; and (C) a sonic device (Sonosurgery ® ). The time used for biopsy collection was recorded, and an evaluation of the quality of the biopsies obtained was performed. The specimens were subsequently prepared for ground sections, and tissue‐to‐implant contact percentages ( TIC %) were evaluated in a stereomicroscope. Results Time needed for biopsy collection in Groups A and B was between 2 and 3 min, while in C, it amounted to 10–11 min. The differences between Group C and the other two groups were statistically significant ( P < 0.00006). Group C showed significantly greater volumes of tissue around the apex of the implants compared with the other two groups ( P < 0.027). Groups A and C showed biopsies with higher quality compared with Group B ( P < 0.05). Group C presented a higher TIC % compared with the other two groups ( P < 0.008). Conclusion Compared with the use of trephines, the use of a sonic device for harvesting biopsies resulted in higher‐quality biopsies and generated smaller residual defects. However, the harvesting was more time‐consuming and was limited to one aspect of the implants.
