The purpose of this study was to formulate and evaluate an adhesive resin with tantalum oxide. Ta2O5 was evaluated by scanning electron microscopy and laser diffraction. The adhesive was formulated with methacrylate monomers and photoinitiators. Ta2O5 was added into the adhesive at 1, 2, 5 and 10 wt%. One group remained without filler (control group). Ta2O5 distribution, radiopacity (n=5), degree of conversion (DC) (n=3), softening in solvent (n=5) and ultimate tensile strength (UTS) (n=10) were evaluated. Data were analyzed by one-way ANOVA and Tukey's test (α=0.05). Spherical nanometric Ta2O5 was arranged in 3.35 µm particles. The groups over 5 wt% presented higher radiopacity (p<0.05). The DC ranged from 61.78 (±1.19)% to 67.35 (±1.40)%, with statistical difference from control group over 5 wt% addition (p<0.05). There was no difference in softening in solvent (p>0.05) and UTS (p>0.05). Tantalum oxide is a promising alternative for adhesive formulation and it could be further tested for biomimetic remineralization.

“…This structure allows to achieve Osseoincorporation, a combination of osseointegration and bone in growth into the porous structure as demonstrated by in vivo (20)(21)(22) and in vitro (23) studies and by histologic testing in transcortical canine (24,25) and human (26) models. With respect to the conventional titanium alloy implants (27)(28)(29)(30)(31), the Secondary Stability is increased in PTTM dental implants, which leads to achieve better results in critical situations such as maxillofacial trauma, cleft and lip palate (32,33) and post-oncologic patients. This study represents the first clinical trial of PTTM dental implants in post-oncological patients and our preliminary results indicate that PTTM dental implants could have a clinical efficacy in prosthetic rehabilitation of these patients.…”

SummaryAim. The aim of this study is to present 18 months follow-up results of porous tantalum trabecular metal-enhanced titanium dental implant (PTTM) in implant supported prosthesis in postoncological patients. Materials and methods. A total of 25 PTTM implants were placed in each jaw of 6 patients that met specific inclusion and exclusion criteria. Resonance Frequency Analysis (RFA) was conducted and Implant stability was recorded in ISQ values (Osstell ISQ, Osstell AB, Goteborg, Sweden) at implant placement and after 2,4,6,12 and 18 months of functional loading. Mean bone loss was also evaluated at the same interval of time on each periapical radiographs, bone levels were calculated by measuring the distance from the implant shoulder to the first bone to implant contact.

“…In particular, active bone remodeling is stimulated by bone disease and complications including estrogen deficiency in postmenopausal osteoporosis, osteoarthritis, fracture healing, and implantation surgery. [2,6,7,15,16,17,18] As a result, heterogeneity of bone tissue mineral density (TMD) increases (Fig. 1).…”

Mineral density distribution of bone tissue is altered by active bone modeling and remodeling due to bone complications including bone disease and implantation surgery. Clinical cone beam computed tomography (CBCT) has been examined whether it can assess oral bone mineral density (BMD) in patient. It has been indicated that CBCT has disadvantages of higher noise and lower contrast than conventional medical computed tomography (CT) systems. On the other hand, it has advantages of a relatively lower cost and radiation dose but higher spatial resolution. However, the reliability of CBCT based mineral density measurement has not yet been fully validated. Thus, the objectives of this review are to discuss 1) why assessment of BMD distribution is important and 2) whether the clinical CBCT can be used as a potential tool to measure the BMD. Brief descriptions of image artefacts associated with assessment of gray value, which has been used to account for mineral density, in CBCT images are provided. Techniques to correct local and conversion errors in obtaining the gray values in CBCT images are also introduced. This review can be used as a quick reference for users who may encounter these errors during analysis of CBCT images.

Abstract: Cortical and apical implant threads, combined with the porous section, were able to stabilize the experimental implant to the same degree as the fully threaded control implant.
