Potential impact of prosthetic biomaterials on the periodontium: a comprehensive review.

NATIVIDAD CASTRO ALARCON Artak Heboyan Gustavo Fernandes Norma Samanta Romero Castro (2023)

The success of a prosthetic treatment is closely related to the periodontal health of the individual. The aim of this article was to review and present the importance of prosthetic restorative materials on the condition of the periodontium, the changes that occur in the composition of the subgingival microbiota and the levels of inflammatory markers in gingival crevicular fluid. Articles on the influence of different prosthetic restorative materials on subgingival microbiota and proinflammatory cytokines were searched for using the keywords ¿prosthetic biomaterials¿, ¿fixed prosthesis¿, ¿periodontal health¿, ¿subgingival microbiota¿, ¿periodontal biomarkers¿ and ¿gingival crevicular fluid¿ in PubMed/Medline, Science Direct, Scopus and Google Scholar. The type of material used for prosthesis fabrication together with poor marginal and internal fit can result in changes in the composition of the subgingival microbiota, as well as increased accumulation and retention of dentobacterial plaque, thus favoring the development of periodontal disease and prosthetic treatment failure. Biological markers have helped to understand the inflammatory response of different prosthetic materials on periodontal tissues with the main purpose of improving their clinical application

in patients who need them. Metal-free ceramic prostheses induce a lower inflammatory response regardless of the fabrication method; however, the use of CAD/CAM systems is recommended for their fabrication. In addition, it is presumed that metal-ceramic prostheses cause changes in the composition of the subgingival microbiota producing a more dysbiotic biofilm with a higher prevalence of periodontopathogenic bacteria, which may further favor periodontal deterioration.

Introduction: the elevation of the transcrestal floor of the maxillary sinus consists of the vertical reconstruction of the atrophic alveolar ridge in an apical direction, with which it is possible to place the correct number and length of oral implants. Objective: to describe the procedure of a case of transcrestal maxillary sinus floor elevation with the placement of three dental implants. Clinical case: 62 year old female patient with missing teeth 16, 25 and 26. Treatment: three implants were placed to replace the missing teeth. Due to the decrease in height of the remaining alveolar ridge due to pneumatization of the maxillary sinuses, elevation of the sinus floor was planned with the transcrestal Summers¿s technique and placement of graft material. Results: by means of the grafts, sufficient height was achieved for the correct stability of the implants, each área had an average gain of 3 mm in bone height, with which length was obtained to give the implants adequate primary stability. Conclusion: sinus floor elevation with a transcrestal approach is a good alternative for rehabilitation with implants in the posterior edentulous sector, associated with pneumatization of the maxillary sinuses.
