- Clinical performance comparing titanium and titanium–zirconium or zirconia dental implantsPublication . Fernandes, Paulo Rafael Esteves; Otero, Ada Isis Pelaez; Fernandes, Juliana Campos Hasse; Nassani, Leonardo Mohamad; Castilho, Rogerio Moraes; Fernandes, Gustavo Vicentis de OliveiraObjectives: This study aimed to compare clinical results between titanium (Ti), zirconia (Zr), or titanium–zirconium (TZ) dental implants and to analyze survival rate (SR), bleeding on probing (BoP), marginal bone loss (MBL), and/or probing depth (PD). Data source: Manual and electronic searches were conducted (PubMed and Web of Science) to identify randomized controlled trials that compared the outcomes of at least two implant types (control and test group) within the same study. The focused question was determined according to the PICOT strategy. Seven studies were included out of 202 research studies initially found. The follow-up periods ranged from 12 to 80 months, and the mean age was from 43.3 to 65.8 years old. The SR for Ti, TZ, and Zr implants ranged from 92.6% to 100%, 95.8% to 100%, and 87.5% to 91.25%, respectively; MBL for Ti, TZ, and Zr implants varied from −1.17 mm to −0.125 mm for Ti, −0.6 mm to −0.32 mm for TZ, and −0.25 mm to −1.38 mm for Zr. Studies showed a low incidence of mucositis and peri-implantitis; however, BoP for Zr was 16.43%, Ti ranged between 10% and 20%, and TZ from 10% to 13.8%. PD for Ti ranged from 1.6 mm to 3.05 mm, TZ was 3.12 mm (only one study), and Zr ranged from 2.21 mm to 2.6 mm. Conclusion: All three types of implants showed similar tissue behavior. However, the TZ group had better results when compared with Ti and Zr for SR, MBL, and BoP, except for PD. Furthermore, the worst SR was found in the Zr implants group.
- Sinus lift associated with leucocyte‐platelet‐rich fibrin (second generation) for bone gain: a systematic reviewPublication . Otero, Ada Isis Pelaez; Fernandes, Juliana Campos Hasse; Borges, Tiago; Nassani, Leonardo; Castilho, Rogerio de Moraes; Fernandes, Gustavo Vicentis de OliveiraThe purpose of this systematic review was to analyze sinus lifting procedures and to compare the efficiency of this treatment associated with the second generation of platelet‐rich fibrin related to its effects on bone gain and to clarify the regenerative efficacy in sinus lift procedure, whether alone or as a coadjutant to other bone graft materials. The PICOT question was, “In clinical studies with patients needing a maxillary sinus lift (P), does the use of PRF either alone (I) or in conjunction with other biomaterials (C) improve the clinical outcome associated with bone gain and density (O), with at least three months of follow‐up (T)?” An electronic search was conducted in the MEDLINE (PubMed), Science Direct, and Scopus databases through a search strategy. A total of 443 articles were obtained from the electronic database search. Sixteen articles met all criteria and were included in this review. Within the limitation of this study and interpreting the results carefully, it was suggested that a higher risk for implant failure after a sinus elevation might be seen in patients with residual bone ≤4 mm, and PRF application was effective, suggesting reducing the time needed for new bone formation.
- Sinus lift associated with second generation of autologous platelet concentrates : a systematic reviewPublication . Otero, Ada Isis Pelaez; Borges, Tiago Gonçalves Ferreira; Fernandes, Gustavo Vicentis de OliveiraIntroduction. The purpose of this systematic review was lift to analyze the available literature of clinical studies involving sinus lifting and comparing the efficiency of 2 nd autologous platelet concentrates (APC) generation related to its effects in bone gain and to clarify the regenerative efficacy of APC in sinus lift procedure, whether alone or as a coadjutant to other bone graft materials. Material and methods. This systematic review was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) guidelines (1) with the focused question being determined according to the Population, Intervention, Comparison and Outcome, Follow-up (PICO) strategy. The protocol for this systematic review was registered on PROSPERO. The focused question for the present review was as follows: “In clinical studies with patients needing a maxillary sinus lift (P), does the use of ACPs either alone (I) or in conjunction with other biomaterials (C) improve the clinical outcome associated with bone gain and density (O), with at least 3 months of follow-up? An electronic search was conducted by two reviewers (A.I.P. and G.V.O.F.), independently, either electronic as manual search, through MEDLINE (PubMed), Science Direct, and Scopus databases with a platformspecific search strategy combining terms such as “sinus floor elevation”, “sinus augmentation”, “platelet-rich fibrin”, “second generation”, or “PRF”, and variables. Results. A total of 443 articles were obtained from the electronic database search, 67 on PubMed, 129 on Science Direct, and 247 on Scopus. An additional publication was considered from the manual search through the references of the included articles. After a full-text review, a total of 16 articles met all the criteria and were included in this review. Conclusion. Through the use of APCs in sinus augmentation the time required for bone graft maturation may be significantly reduced thus allowing sooner implant insertion, however overall long-term bone development did not show any significant difference.
