“…Both kinds are pure dense PTFE, without reinforcements, containing surface macro-roughness features (ridges vs. dents), thus differing only in physical features and polymer microstructure. One of them (designated PTFE-W) is well-established in clinical use [ 15 , 19 ], while the other one (PTFE-B) is new but proved to be effective in alveolar ridge preservation [ 31 ]. The effect of diverse microstructural features of chemically identical materials on bacterial adhesion has been observed for other materials; for example, bacterial adhesion was affected by crystalline vs. amorphous phase on Ti-based material for orthopaedic implants [ 32 ].…”

Bacterial contamination of the membranes used during guided bone regeneration directly influences the outcome of this procedure. In this study, we analyzed the early stages of bacterial adhesion on two commercial dense polytetrafluoroethylene (d-PTFE) membranes in order to identify microstructural features that led to different adhesion strengths. The microstructure was investigated by X-ray diffraction (XRD), differential scanning calorimetry (DSC), and Fourier transform infrared (FTIR). The surface properties were analyzed by atomic force microscopy (AFM), scanning electron microscopy (SEM), and surface free energy (SFE) measurements. Bacterial properties were determined using the microbial adhesion to solvents (MATS) assay, and bacterial surface free energy (SFE) was measured spectrophotometrically. The adhesion of four species of oral bacteria (Streptococcus mutans, Streptococcus oralis, Aggregatibacter actinomycetemcomitas, and Veilonella parvula) was studied on surfaces with or without the artificial saliva coating. The results indicated that the degree of crystallinity (78.6% vs. 34.2%, with average crystallite size 50.54 nm vs. 32.86 nm) is the principal feature promoting the adhesion strength, through lower nanoscale roughness and possibly higher surface stiffness. The spherical crystallites (“warts”), observed on the surface of the highly crystalline sample, were also identified as a contributor. All bacterial species adhered better to a highly crystalline membrane (around 1 log10CFU/mL difference), both with and without artificial saliva coating. Our results show that the changes in polymer microstructure result in different antimicrobial properties even for chemically identical PTFE membranes.

“…A commonly applied socket preservation technique involves a flapless approach and bone grafting of the residual socket to prevent bone loss immediately after extraction [ 7 , 8 ]. However, it was demonstrated that a lack of socket sealing could lead to clinical failures [ 26 , 27 ]. To overcome these limitations, various soft tissue management techniques have been proposed, including advanced coronal flap [ 28 ], epithelial-connective soft tissue graft [ 29 ], resorbable porcine collagen matrix [ 11 ], or intentionally exposed, not resorbable membranes [ 12 ].…”

Histological and Histomorphometric Evaluation of Post-Extractive Sites Filled with a New Bone Substitute with or without Autologous Plate Concentrates: One-Year Randomized Controlled Trial

The purpose of the present study was to evaluate the histological and histomorphometric characteristics of post-extraction sites grafted with decellularized bovine compact bone from bovine femur, mixed and unmixed with leukocyte- and platelet-rich fibrin after four months of healing. This study was designed as a randomized controlled trial of parallel groups. Patients in need of a single, implant-supported restoration to replace a hopeless tooth were recruited for tooth extraction and implant placement four months after socket preservation procedure. After tooth extraction, patients were randomly allocated to receive decellularized bovine compact bone from bovine femur, mixed and unmixed with leukocyte- and platelet-rich fibrin. After four months of healing, tapered implants were inserted with an insertion torque between 35 and 45 Ncm. Two months later, implants were loaded with screw-retained definitive crowns. Outcome measures were implant (ISR) and prosthesis (PSR) survival rates, complications, histological and histomorphometric analyses, radiographic marginal bone-level changes, and patients’ satisfaction. Clinical data were collected up to one year after tooth extraction and socket preservation procedures. Thirty patients were consecutively enrolled in the trial (15 in each group). Unfortunately, due to the COVID-19 pandemic, bone samples were collected only in 19 patients. Two implants failed before definitive prosthesis delivery (ISR 93.3%). No prosthesis failed (PSR 100%). Three complications were experienced in the control group. The mean bone percentage was 40.64 ± 18.76 in the test group and 33.40 ± 22.38 in the control group. The difference was not statistically significant (p = 0.4846). The mean soft tissue percentage was 32.55 ± 19.45 in the test group and 55.23 ± 17.64 in the control group. The difference was statistically significant (p = 0.0235). The mean residual graft was 24.59 ± 18.39 in the test group and 11.37 ± 12.12 in the control group. The difference was not statistically significant (p = 0.0992). Mean marginal bone loss, as well as patient satisfaction, showed no differences between groups. With the limitations of the present study, socket preservation with L-PRF mixed with decellularized bovine compact bone demonstrated favorable results, comparing with decellularized bovine compact bone from bovine femur alone. Further studies with larger sample size and longer follow-up are needed to confirm these preliminary results.

“…A few types of coronal seal materials have been used to block infiltration of soft tissue into the lower bone graft area in flapless ridge preservation; these include membranes and collagen plugs [16,20,31,41]. Sockets have previously been sealed with a porcine collagen matrix, epithelial connective tissue grafts or membranes, and these approaches all yielded the desired outcomes [16,20,[41][42][43]. Currently, leukocyte-and platelet-rich fibrin membrane is also used to seal post-extraction sockets [44].…”

This retrospective study compared the effects of different extraction sockets when using flapless ridge preservation during dental implant therapy. The extraction sockets were divided into four groups: Class I, intact soft tissue wall and bone walls; Class II, intact soft tissue wall with the destruction of at least one bone wall; Class III, the recession of all soft tissue walls by ≤5 mm; and Class IV, the recession of at least one soft tissue wall by >5 mm. We compared clinical parameters of dental implant therapy using flapless ridge preservation among these groups. Seventy patients with 92 dental implants, including 53 maxillary and 39 mandibular implants, involving flapless ridge preservation were enrolled. The implant survival rate was not affected by socket morphology. Total treatment time from extraction to final prosthesis placement was significantly longer in Class II and III than in Class I, among the maxillary sockets. However, there was no significant difference in the total treatment time among the different groups in the mandible. Therefore, implant survival rates did not differ according to socket morphology; however, total treatment time was significantly affected by socket morphology in the maxilla and was longer in socket classes associated with periodontitis.
