Use of sonic instruments for implant biopsy retrieval


Ferri, Mauro; Lang, Niklaus P; Angarita Alfonso, Edwin Elías; Bedoya Quintero, Iván Darío; Burgos, Enrique Mejía; Botticelli, Daniele (2015). Use of sonic instruments for implant biopsy retrieval. Clinical Oral Implants Research, 26(11):1237-1243.

Abstract

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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
