Evaluation of the primary stability in dental implants placed in low density bone with a new drilling technique, osseodensification: an in vitro study
2020
Background Primary stability is an important key determinant of implant osseointegration. We investigated approaches to improve primary implant stability using a new drilling technique termed osseodensification (OD), which was compared with the conventional under-drilling (UD) method utilized for low-density bones. Material and Methods We placed 55 conical internal connection implants in each group, in 30 low-density sections of pig tibia. The implants were placed using twist drill bits in both groups; groups Under Drilling (UD) and Osseodensification (OD) included bone sections subjected to conventional UD and OD drilling, respectively. Before placing the implants, we randomized the bone s…
Is clinical experience important for obtaining the primary stability of dental implants with aggressive threads? An ex vivo study
2018
GECKILI, ONUR/0000-0002-7852-3915; dayan, suleyman cagatay/0000-0003-3081-9618; Bilhan, Hakan/0000-0003-1787-3003 WOS:000460131200015 PubMed ID: 30818319 Background: The aim of this study was to investigate the clinicians' experience on maintaining the primary stability of implants with aggressive threads belonging to a novel dental implant system. Material and Methods: Three hundred implants with aggressive threads were inserted in fresh bovine ribs mimicking Type IV bone by five clinicians which were classified according to their previous experience of total number of implant insertion. An independent examiner measured the primary stability of all implants after insertion by using resonan…
Diagnosis and Planning in Immediate Loading: Surgical Diagnosis
2019
For several decades, two-dimensional images were the only available for the surgical diagnosis prior to implant placement. The introduction of digital radiology and software applications for three-dimensional imaging has increased the prospects of success in implant diagnosis and surgical placement. The CBCT is definitely more precise and complete than panoramic radiography, but it is not always mandatory for every case. Success for fixed implant-supported rehabilitations, especially in immediate provisionalization techniques, depends on accurate pre-surgical evaluation of the following issues: (1) recognize feasible restoration procedures to rehabilitate patient edentulism; (2) list all th…
Resonance frequency analysis-reliability in third generation instruments : Osstell mentor ®
2012
Few studies assess repeatability and reproducibility in registers of resonance frequency analysis (a value of dental implant stability). Objective: Few studies assess repeatability and reproducibility in resonance frequency analyses (implant stability evaluation). This study is aimed at assessing reliability (repeatabilty and reproducibility) in the Osstell Mentor® system using the intraclass correlation coefficient (ICC) as the statistical method. Study Design: ISQ measurements of RFA were carried out by means of the Osstell Mentor ® instrument in 58 implants in 19 patients. Six measurements were performed on each implant by means of two different Smart-Pegs (I and II). Three consecutive m…
