“…5 Additionally, compared to two implant retained overdentures (TIO), which exhibit a two-dimensional movement, the prosthesis's movement in SIO is three-dimensional, making it biomechanically far more complex. 6 There are several attachment systems for implant-assisted overdentures that have been used, but each one has drawbacks. Attachments used in conjunction with implants were found to enhance the retention, stability, and support of overdentures together with the implants, thus increasing their longevity.…”

Aim: Evaluation of the effectiveness of different types of attachment systems on single implants in mandibular implantassisted overdentures. Materials and Methods: This was a randomized clinical trial on fourteen completely edentulous patients selected with adequate width and height in the anterior region of the mandible. Selected patients were divided randomly into two equal groups of seven patients each. Group A: Patient with removable mandibular implant assisted overdenture with ball and Oring attachment. Group B: Patient with removable mandibular implant assisted overdenture with silicon soft liner as attachment. Gingival index, bleeding index, probing depth around the implants, and retention of overdenture by digital force gauge was evaluated at 0,6,12,18 months after insertion of the prosthesis. The data were collected and statistically analyzed by independent t-test and a Post Hoc Test using IBM SPSS 20 at a 5% level of significance. Results: All the implants in both groups successfully achieved osseointegration. The results for the gingival index, bleeding index, and periodontal pocket demonstrated higher values in the O-ring group compared to the silicon soft liner used as a female housing. Nevertheless, a notable difference was observed in O-ring retention compared to the silicon soft liner for female housing from baseline to the 18-month mark, which was statistically significant. Conclusion:The study concluded that, in single implant-assisted overdentures with different types of attachments, the group using a silicon soft liner as the female attachment exhibited a more positive effect on gingival health. However, it demonstrated less retention compared to the O-ring attachment group.

“…Additionally, it should be nontoxic, not affect oral soft tissues, insoluble in saliva, and lightweight. Polymers have been used to make artificial teeth for persons who are missing teeth and need artificial restoration [12,13], like Poly methyl Methacrylate (PMMA) resin, which is frequently used in dental laboratory to fabricate and repair orthodontic retainers and to reline prostheses and permanent crowns in dental clinics and industry (like fabrication of artificial teeth). PMMA has many benefits for dental applications, such as the capacity to tolerate high temperatures, ease of laboratory manipulation, lightness, low cost, stability of the oral environment, esthetic appeal, color, and lack of toxicity or mutagenicity to the oral tissues [14,15,16].…”

The current work focuses on the preparation of magnesium oxide nanoparticles using aqueous magnesium chloride salts and sodium hydroxide powder by a simple chemical precipitation method and at an annealing temperature of 700 °C for 6 hours. The structural and morphological properties of the magnesium oxide nanoparticles were investigated using X-ray diffraction (XRD). Polycrystalline cube and using the Scherer equation showed a crystalline size of 17.23 nm. EDS analyzes showed high purity. Scanning electron microscopy (FESEM) showed the spherical shape of the magnesium oxide particles. With particle size within the range (65-185) nm. While a (PMMA)-HAP nanocomposite was synthesized. -MgO) for use in dental applications such as fillings and dentures. A nanocomposite (PMMA-HAP-MgO) was manufactured by manual molding method by strengthening the poly methyl methacrylate polymer with certain weight ratios(1%,5%,and 10%) from a mixture of nano powder where the added ratios were (99%PMMA-1%HAP,95%PMMA-7.4%HAP-0.3%MgO,and 90%PMMA-9.4%HAP-0.3%MgO). The topographical properties (surface roughness) of the nanocomposite samples were studied by testing them with an atomic force microscope. The results showed an increase in the value of pure PMMA, where the use of nanoparticle filler by 5% (4.7% HAP -0.3% MgO) affected both the roughness and the root mean square ratio of the distribution of nanoparticles on the surface of the composite and the shape of the particles led to a roughness more than the polymer pure. The antibacterial activity of the polymeric overlay was examined on the bacteria that cause dental caries for (Streptococcus mutans), where the zone of inhibition were (1 mm, 2 mm, 5 mm) for the nanocomposite and no activity for pure PMMA.
