“…For these reasons, manufacturers are in continuous research into implant design in order to improve PS in low quality bone ( 15 , 16 ). Radhex® (Inmet-Garnick, S.A., Guadalajara, Spain) uses a subtractive surface treatment by shot blasting and incorporates a double thread implant design which they ensure to improve PS.…”

BackgroundPrimary stability (PS) is a key factor for implant survival rate and depends on implant design or bone quality. The aim of this study was to compare different thread designs implants, evaluating PS with periotest values (PV) and implant stability quotient (ISQ) values through resonance frequency analysis (RFA).Material and MethodsA total of 60 implants (Radhex®, Inmet-Garnick S.A., Guadalajara, Spain) were placed in freshly bovine ribs in vitro. Two designs were used: 30 tapered body with single thread design (PHI) and 30 tapered body with double thread design implants (PHIA). Both designs were 4mm wide and 12mm long. Implants were placed according to manufacturer’s guidelines. Osstell™ and Periotest® devices were used to evaluate PS by a blinded independent observer. Computed tomographies (CTs) of the ribs were made (BrightSpeed Series CT systems, GE Healthcare, Milwaukee, WI, USA) and bone quality surrounding each implant was evaluated in Hounsfield Units (HU) using Ez3D Plus software (Vatech Co., Korea). Bone quality was classified according to Misch and Kircos in D1, D2, D3 or D4.ResultsAll implants were mechanically stable. Only implants placed in D3 bone (350-850 HU) were selected for the study: 28 PHI and 26 PHIA. The one way ANOVA showed significant difference (p<0.005) among two implants designs in ISQ values (61,55 ± 6,67 in PHI and 68,94 ± 5,82 in PHIA). No significant difference (p = 0,171) was shown in PV between two designs (-4,47 ± 1,39 in PHI and -4,77 ± 0,87 in PHIA).ConclusionsHigher PS was found using Osstell™ device in implants with double thread design (PHIA) in comparison to implants with single thread design (PHI) in D3 bone. Key words:Dental implant, primary stability, Osstell, Periotest, bone quality, implant design.

“…The additional implant length and/or the greater diameter were also proved beneficial in this regard [ 13 , 14 , 15 ]. Bovine ribs were chosen to mimic the in vivo low-density bone as used in various previous studies [ 16 , 17 , 18 ].…”

The achievement of sufficient implant stability in poor quality bone seems to be a challenge. Most manufacturers develop special dental implants, which are claimed to show higher stability even in very soft bone. The aim of this experimental study was to compare two recently introduced dental implants with differing thread designs. A total of 11 implants of each group were inserted in the part of the fresh bovine ribs, corresponding to very soft bone. The primary stability was measured with resonance frequency analysis (RFA) and Periotest; the average of two measurements for each method and for each implant was taken and statistical analysis was applied. The highest stability values were obtained with the ICX Active Master implants, followed by the Conelog® Progressive-Line implants placed with the very soft bone protocol. The primary stability values of the Conelog® Progressive-Line implants inserted by the very soft bone protocol and the ICX Active Master implants placed with the standard protocol showed sufficient stability for immediate loading in low-density bone. Within the limitations of this study, the thread design of the implants and underdimensioned implant bed preparation seem to be effective for better primary stability in cancellous bone.

Background/Aim. This study aimed to examine the correlation of CBCT analysis derived bone density with primary stability value. Methods. Clinical prospective experimental study was conducted in 38 healthy patients missing one tooth in the lateral region. It was planned to install Bredent Blue Sky Narrow self-taping dental implants with dimensions 3.5 x 10 mm. During preoperative preparation, a CBCT scan was performed on Planmeca apparatus, followed by pre-implantation measurements and planning in the CBCT apparatus software (Romexis). The mean value of the average bone volume is automatically generated and expressed in Hounsfield units. Upon implant placement, we performed measurements of the primary implant stability using Osstell apparatus. Results. Of the thirty-eight patients included in the study, there were 68.4% male patients and 31.6% female patients. The arithmetic mean of the measured bone density of all subjects in the study amounted to 536.2 HU. The arithmetic mean of dental implant primary stability for all subjects in the study was 68.7 ISQ. There is statistically significant strong positive connection between HU and ISQ (r = 0.744, p <0.001). Higher HU values are connected to higher ISQ values. In the multivariate linear regression model, statistically significant predictors of higher ISQ values are as follows: male (B = 4.669; p = 0.047) and higher HU values (B = 0.032; p <0.001). Conclusion. We have shown in our clinical study that there is a statistically significant strong positive correlation between the bone density expressed in HU units measured in the software of the CBCT device and the primary stability of dental implants expressed in ISQ units.
