“…34 Other factors that may interfere in the adhesion of microorganisms are the presence of other species on the surface and the presence of saliva. 7,26,34 Positive correlation was observed between E. coli and C. albicans (P < .001/r = .759). This result corroborated with another, which identified E coli as capable of inhibiting effectively the formation of hypha by fungal cells (C. albicans) only when induced and modified by hydroxyphenylacetic acid (HPA).…”

“…Full‐arch implant‐supported fixed prostheses are widely used as clinical intervention for edentulous mandibles 1‐4 . Despite the favourable long‐term results obtained with prosthetic rehabilitations on implants, biological and technical complications can be verified 3,5‐7 . Peri‐implantitis, peri‐implant mucositis, prosthetic stomatitis, tissue hyperplasia, as well as problems concerning aesthetics and phonetics are common 2,5 .…”

Objective The purpose of this study was to quantify the area covered by biofilm and identify bacteria and yeasts present in mandibular acrylic resin full‐arch implant‐supported fixed prostheses. Background Biofilm control of implant‐supported fixed prosthesis is hampered by their design, and it can cause oral and systemic problems, mainly in immunocompromised patients like the elder. Knowledge about microbiota reinforces the awareness about the need for periodic professional cleaning maintenance. Materials and methods Twenty prostheses were unscrewed, washed in 0.89% sodium chloride, stained with eosin 1% and photographed. The area covered by biofilm was digitally delimited and quantified. Biofilm samples were collected, diluted up to 1:107, seeded in chromogenic agar media and incubated for 48 hours, at 37°C, for counting of colony‐forming units (CFU/mL). DNA hybridization was performed to complement the identification and quantification of microorganisms. Data were analyzed using Mann‐Whitney test, Spearman correlation and Fisher's exact test (α = .05). Results An average of 62% of the gingival surface of the prostheses was covered by biofilm. Enterococcus spp. (5.82 ± 1.38 log10CFU/mL) and Staphylococcus aureus (5.75 ± 2.02 log10CFU/mL) showed higher prevalence in cultures. Patients with five implants had less biofilm compared to those with four implants (P = .031) but had higher Escherichia coli counts (P = .039). In DNA hybridization, Streptococcus pneumoniae, Veillonella parvula and Fusobacterium nucleatum presented higher quantification and were present in all the samples; patients over 65 years old contained more Candida tropicalis (P = .049); prostheses on five implants presented lower quantification for several species. Conclusion Biofilm was present on all prostheses, containing potentially pathogenic microorganisms. The number of implants may play a role in quantification of biofilm and in microorganism counts.

Characterization of the Oral Microbiome in Wearers of Fixed and Removable Implant or Non-Implant-Supported Prostheses in Healthy and Pathological Oral Conditions: A Narrative Review

Oral commensal microorganisms perform very important functions such as contributing to the health of the host. However, the oral microbiota also plays an important role in the pathogenesis and development of various oral and systemic diseases. The oral microbiome may be characterized by a higher prevalence of some microorganisms than others in subjects with removable or fixed prostheses, depending on oral health conditions, the prosthetic materials used, and any pathological conditions brought about by inadequate prosthetic manufacturing or poor oral hygiene. Both biotic and abiotic surfaces of removable and fixed prostheses can be easily colonized by bacteria, fungi, and viruses, which can become potential pathogens. The oral hygiene of denture wearers is often inadequate, and this can promote oral dysbiosis and the switch of microorganisms from commensal to pathogens. In light of what emerged from this review, fixed and removable dental prostheses on teeth and on implants are subject to bacterial colonization and can contribute to the formation of bacterial plaque. It is of fundamental importance to carry out the daily hygiene procedures of prosthetic products, to design the prosthesis to facilitate the patient’s home oral hygiene practices, and to use products against plaque accumulation or capable of reducing oral dysbiosis to improve patients’ home oral practices. Therefore, this review primarily aimed to analyze the oral microbiome composition in fixed and removable implant or non-implant-supported prostheses wearers in healthy and pathological oral conditions. Secondly, this review aims to point out related periodontal self-care recommendations for oral dysbiosis prevention and periodontal health maintenance in fixed and removable implant or non-implant-supported prostheses wearers.

With the constant development of radiation and computer technology, the field of implant dentistry is also experiencing a digital revolution, including digitalized data acquisition, computer-aided virtual planning, computer-guided implant surgery and restoration, etc. The digitalized clinical protocol promotes a more standardized and accurate dental implant treatment, which certainly will reduce the occurrence of complications for dental implant treatment, and achieve more predictable long-term stability in both function and aesthetics, This paper summarized the digital collection, digital smile design, computer-guided surgery planning, and implant supported prosthesis design in combined with the development status of digital technique, and the future trend.
