RESUMO
Background: Because of its integrated design and possible benefits over conventional two-piece systems, single-piece implant systems have grown in favor in the field of dental implantology. There is, however, still a dearth of information about their long-term stability and clinical results. The purpose of this study was to assess the clinical results, such as implant survival rates, peri-implant tissue health, and marginal bone levels, to determine the long-term stability of single-piece implant systems. Methods: About 127 individuals who got single-piece implants at the tertiary care center were the subject of a retrospective analysis. Standardized procedures were followed for implant implantation, and patients were monitored for at least five years afterward. Through radiographic analysis and clinical tests, clinical indicators such as marginal bone levels, peri-implant tissue health, and implant survival rates were evaluated. Results: With low marginal bone loss and good peri-implant tissue health, the research showed a high implant survival rate of 96.5%. A statistical study revealed significant relationships between marginal bone loss (P < 0.01), peri-implant tissue health (P < 0.05), and implant survival. Conclusion: In this study, single-piece implant devices showed good long-term durability and clinical results. These results confirm its effectiveness as a dependable dental rehabilitation alternative, highlighting the significance of preserving the health of the peri-implant tissue and reducing marginal bone loss to guarantee implant success.
RESUMO
BACKGROUND: The classic maxillary full denture covers the whole palate, preventing the tongue from touching the denture base tissues itself. Thus, it has deleterious effects on cortical brain function and the ability to understand spoken language. AIM: This study aimed to determine the effect of anterior palatal surface modifications of the complete denture on speech intelligibility oral perception and cortical brain function activity. METHODS AND MATERIALS: This study compared the speech clarity, oral discernment, and cortical mind capability activity of complete denture wearers in three study groups: a) complete denture wearers with a small opening (SO) in the maxillary front palatal base; b) complete denture patients who wear regular complete denture; c) complete denture patients who did not wear complete denture; and d) complete denture patients who wear a functionally contoured modified palate (FCMP). Patients with no teeth at all underwent four phases of testing to assess their cognitive abilities and speech quality (pitch and volume). In the first phase, partial dentures were used. During phase 2, a conventional full denture was inserted. In the third phase, a palatal base denture was functionally altered. In phase 4, dentures with a little aperture at the front of the palatal base were used. Results: The values of pitch and intensity of sound in category A with FCMP modification I were 180.76 ± 24.12 and 73.27 ± 9.74, respectively. On the other hand, the values of pitch and intensity of sound in category B with FCMP modification I were 185.41 ± 27.29 and 73.91 ± 8.31, respectively. The values of pitch and intensity of sound in category A with SO modification II were 188.52 ± 21.11 and 76.13 ± 5.21, respectively. On the other hand, the values of pitch and intensity of sound in category B with SO modification II were 194.59 ± 24.02 and 75.21 ± 6.12, respectively. The findings for values of pitch and intensity were statistically significant among the four phases (p < 0.001). The highest speech intelligibility and cortical brain function were observed in phase 4 in both categories A and B, with the highest scores by experts of 3.21 and 3.42, respectively. Conclusion: Based on the findings of this in vivo investigation, it can be concluded that using modified dentures (modification types I and II) following denture installation improves speech intelligibility, oral perception, and cortical brain function activity.

RESUMO
Introduction: The invention of dental implants has replaced the fixed partial dentures for the replacement of the teeth. Hence, in the present study, we compared the surface characteristics of various zirconia dental implant systems. Materials and Methods: We conducted an in vitro comparative study of 50 implants of the dental implant systems "Straumann pure ceramic implants (SC) and Bredent dent whiteSKY™ (BW)." Scanning electron microscopy (SEM) was used to compare the groups for the surface characters at the different regions of the implant surface. Results: SC showed deep markings on the surface and droplets, and BW showed smoother surface and bigger droplets under the SEM. Conclusion: SC may perform better in the clinical conditions as the surface characters are better than the BW.
