“…In condensable materials, bacterial and fungal 38) adherence are to be expected due to microleakage effects that may be caused by polymerization shrinkage or inadequate adhesion to the walls of the screw access channel. In all tests, condensable materials showed the lowest adhesion of microorganisms, and cotton pellets and endo-frost pellets the highest adhesion.…”

“…Although sterilizable, the surface texture may further support re-contamination during clinical application. PTFE resulted in distinctly reduced adhesion despite its fiber structure 38,39) . The thermoplastic polyhalogenolefine shows extremely low surface-free energy, resulting in smooth and inert material surfaces that impede bacterial adhesion 16,39) .…”

Unsuccessfully sealed screw access channels of prosthetic implant abutments may lead to malodor or peri-implant diseases in gingival tissues adjacent to implant-supported restorations. Therefore, 72 sets of screw channel analogs with six different materials incorporated (Polytetrafluoroethylene (PTFE), wax, gutta-percha, cavit, endofrost-pellets and cotton pellets) were exposed (2.5 h, 37°C) to Streptococcus mutans, oralis and Candida albicans suspensions. Bacterial adherence was quantified by using the fluorescence dye, Alamar Blue/resazurin, and an automated multifunctional reader. For quantification of fungal adherence the ATP-based bioluminescence approach was used. High relative fluorescence and luminescence intensities (>10,000), indicating high adhesion of streptococci and fungi were found for cotton and endofrost-pellets and low intensities (<5,000) for wax, gutta-percha, cavit and PTFE. The quantity of bacterial and fungal adhesion differed significantly between the assessed various sealing materials. In conclusion and within the limitations of this study, wax, gutta-percha, cavit and PTFE should be preferred as sealing materials.

“…Stretching PTFE tape around the abutment before seating the restoration has been proposed to prevent adhesion of excess cement to the gingival part of the abutment . Since the thickness of stretched PTFE tape is less than 50 μm, there is no risk of increasing the peri‐implant sulcus space . On the contrary, since gingival retraction cords could enlarge the peri‐implant sulcus, their use has not been advocated for this purpose .…”

Cement-retained implant-supported prostheses are widely used for restoring missing teeth; however, they show some complications in comparison to screw-retained restorations, such as difficulty in retrieving the restoration and biocompatibility of cement. Therefore, the practitioner should consider several important aspects when using this type of restoration. In this regard, one major concern is appropriate cement selection, with considerations including cement biologic compatibility, methods for limiting the excess cement, ease of removing the excess cement, radiographic view of the cement, and also the possibility of future retrieval of the prosthesis. The aim of this review article was to address most aspects related to this type of prosthesis in terms of cementation.

[12][13][14][15][16][17] Simantasyon tekniği ve kullanılan siman miktarı, taşan siman miktarının azaltılması açısından oldukça önemlidir. Restorasyonların simantasyonu sırasında ihtiyaç duyulan siman miktarı hakkında halen bir rehber bulunmamaktadır.…”
