“…In the present study, the highest RTV was measured in the SLA group after healing of 3 weeks. This positive feature was observed in previous studies, in which SLA-surface implants achieved a high reverse torque resistance (mean 49.84 and 115.2 N/cm after 3- and 6-week healing, respectively) in the early stages of osseointegration [ 18 , 24 ]. It was remarkable that the B-coated surface group (BC) characterized by a lower spatial and hybrid surface roughness demonstrated the lowest early term RTV in this study.…”

“…Bone-to-implant contact (BIC%) and removal torque value (RTV) were designated as the primary outcomes, and relevant data were obtained from similar previous studies [ 18 , 19 ]. The power of the study was expressed as 1–β (β = probability of type II error), and an effect size of 1.978 and 1.484 was found for the BIC% and RTV, respectively.…”

The aim of this study was to compare the topographical, chemical and osseointegration characteristics of sandblasting and acid-etching (SLA) surfaces and dental implants treated by boron compounds. Titanium (Ti) disks (n = 20) were modified using boron (B) and boric acid (H3BO3) and then compared with the conventional SLA surface via surface topographic characterizations. Dental implants (3.5 mm in diameter and 8 mm in length) with the experimental surfaces (n = 96) were inserted into the tibias of six sheep, which were left to heal for 3 and 7 weeks. Histologic, histomorphometric (bone–implant contact (BIC%)) and mechanical tests (removal torque value (RTV)) were performed. The boron-coated surface (BC group) was smoother (Rz: 4.51 μm ± 0.13) than the SLA (5.86 μm ± 0.80) and the SLA-B (5.75 μm ± 0.64) groups (p = 0.033). After 3 weeks, the highest mean RTV was found in the SLA group (37 N/cm ± 2.87), and the difference compared with the BC group (30 N/cm ± 2.60) was statistically significant (p = 0.004). After 7 weeks, the mean RTV was >80 N/cm in all groups; the highest was measured in the H3BO3-treated (BS) group (89 N/cm ± 1.53) (p < 0.0001). No statistically significant differences were found in the BIC%s during both healing periods between the groups. H3BO3 seems to be a promising medium for dental implant osseointegration.

“…The iliac crest site offers the advantages of bone characteristics, the absence of postoperative morbidity, and the ability to conduct a high number of implants test simultaneously; however, although the iliac crest exhibits low bone density, the cortical is thicker relative to the thin cortical of the posterior region of the maxilla, which also shows low bone density. Previous studies- 30,33,36,45 that used sheep models have reported that the animals were euthanized at the end of the experiments; in our study, all animals were kept alive and healthy. The insertion torque value is a direct measure of the bone's cutting resistance during implant insertion surgery.…”

Background and Objective The success rates of dental implants in low-density bone have been reported as a challenge, especially for early or immediate loading in the maxilla posterior area. Nanoscale architecture affects the roughness, surface area, surface energy of the implant and can enhance osseointegration. This study aimed to evaluate the implant-surface topography and biomechanical, histomorphometric, and histological bone responses to a new nanostructured hydroxyapatite surface placed in the iliac crest of sheep. Methods Ten female sheep (2–4 years) received 30 implants (n=10/group): HAnano ® coated (Epikut Plus ® , S.I.N. Implant System, Sao Paulo, SP, Brazil), SLActive (BLX ® , Straumann, Basel, Switzerland), and TiUnite (NobelActive ® , Nobel Biocare, Göteborg, Sweden) surfaces. Scanning electron microscopy with energy-dispersive spectroscopy evaluated the implant surface topography, the insertion torque value, and resonance frequency analysis evaluated the primary stability, bone-implant contact, and bone-area fraction occupancy were evaluated after 14 and 28 days after implant placement. Results The surface morphology was considerably comparable between the implant groups’; however, the TiUnite ® group presented a remarkable different surface. The SLActive ® and TiUnite ® groups presented an insertion torque average of 74 (±8.9) N/cm that was similar to that of HAnano ® 72 (±8.3) N/cm (p >0.05). The resonance frequency evaluated with Osstell ® /SmartPeg ® or Penguin ® /MulTipeg ® showed similar results when assessing implants from the same group. BIC and BAFO significantly increased (p<0.05) throughout the experimental periods to all groups, but BIC and BAFO values were similar among the implants at the same time point. After 4 weeks, bone-implant contact was higher than 80% of the total length analyzed. New bone occupies around 60% of analyzed area around the implants. Conclusion HAnano ® coated surface promoted comparable osseointegration as SLActive and TiUnite in the sheep model. The three tested surfaces showed comparable osseointegration at the early stages of low-density bone repair in the sheep model.

“…This in vivo study on low-density bone used the sheep iliac crest model for implantation, which is suitable for biomedical research due to its similarities to humans in weight, joint structure, bone tissue, and bone regeneration [ 16 , 22 ] and advantages over other experimental animal models in bone composition, metabolism, remodeling, and regeneration time [ 22 ]. Previous studies of dental implant designs and surfaces have used sheep [ 19 – 21 , 23 , 24 ], rabbit [ 7 , 25 , 26 ], and dog [ 27 – 29 ] models. The most commonly used sites in these animals are the mandible [ 27 , 28 ] and tibia [ 29 ] in dogs, the tibia [ 4 , 7 , 25 , 26 ] in rabbits, and the tibia [ 5 , 23 ], iliac crest [ 19 – 21 , 24 ], and mandible [ 30 ] in sheep.…”

Objective This in vivo study, aimed to biomechanically, histomorphometrically and histologically evaluate an implant surface coated with nanostructured hydroxyapatite using the wet chemical process (biomimetic deposition of calcium phosphate coating) when compared to a dual acid-etching surface. Material and methods Ten sheep (2–4 years old) received 20 implants, 10 with nanostructured hydroxyapatite coating (HAnano), and 10 with dual acid-etching surface (DAA). The surfaces were characterized with scanning electron microscopy and energy dispersive spectroscopy; insertion torque values and resonance frequency analysis were measured to evaluate the primary stability of the implants. Bone-implant contact (BIC) and bone area fraction occupancy (BAFo) were evaluated 14 and 28 days after implant installation. Results The HAnano and DAA groups showed no significant difference in insertion torque and resonance frequency analysis. The BIC and BAFo values increased significantly (p<0.05) over the experimental periods in both groups. This event was also observed in BIC value of HAnano group. The HAnano surface showed superior results compared to DAA after 28 days (BAFo, p = 0.007; BIC, p = 0.01). Conclusion The results suggest that the HAnano surface favors bone formation when compared to the DAA surface after 28 days in low-density bone in sheep.
