Trolley waits reach their worst levels on record
Startling NHS statistics show 1,089 patients endured waits of more than 12 hours for treatment in overstretched casualty units in January - the highest since records began in 2010.
CONCLUSION: The immediate loading of short implants is comparable to conventional length implants in terms of implant survival, marginal bone level change, and implant stability quotient value. PMID: 30521662 [PubMed - as supplied by publisher]
CONCLUSION: Reducing interimplant distance may decrease global linear distortions (dR) for intraoral scanner systems, but had no effect on Impregum and the dental laboratory scanner systems. Impregum consistently exhibited the best or second-best accuracy at all implant locations, while True Definition exhibited the poorest accuracy for all linear distortions in both Models A and B. Impression systems could not be consistently ranked for absolute angular distortions. PMID: 30521661 [PubMed - as supplied by publisher]
CONCLUSION: Dynamic surgical navigation is an accurate method for executing CBCT-based computer-aided implant surgery. In addition, an increased experience level of the surgeon with dynamic navigation appears to improve accuracy outcomes. PMID: 30521660 [PubMed - as supplied by publisher]
Authors: Smeets R, Henningsen A, Heuberger R, Hanisch O, Schwarz F, Precht C Abstract PURPOSE: To compare the influence of ultraviolet (UV) irradiation and cold atmospheric pressure plasma (CAP) treatment on surface structure, surface chemistry, cytocompatibility, and cell behavior on zirconia in vitro. MATERIALS AND METHODS: Zirconia samples (TZ-3YSBE) were treated by UV irradiation, oxygen plasma, or argon plasma for 12 minutes each and compared with the nontreated samples. Surface analysis was conducted using scanning electron microscopy, roughness analysis, and x-ray photoelectron spectroscopy. Cell prolife...
Authors: Öhman D, Schaefer C, Nannmark U, Kjeller G, Malmström J Abstract The purpose of this case report was to assess whether patient-specific implants (PSI: Xillocs) and soft tissue flaps contribute in reconstructing large mandibular defects. Five patients with a medical situation and history not suitable for free microvascular bone flaps were operated with PSI and evaluated. The mean follow-up time was 12 months. The excellent fit, convenient surgery, and esthetic outcome were seen as the major advantages. The PSI can, in the authors' experience, be considered as a useful alternative provided they are...
CONCLUSION: On the basis of this preliminary study, it appears that the use of a barrier membrane to cover the lateral bone window during maxillary sinus floor augmentation surgery with a lateral approach reduces the postoperative dislodgement of the bone graft throughout the sinus antrostomy and prevents the bone substitute particles penetrating within the buccal mucosa, which is related to postoperative morbidity.

CONCLUSION: Within the study's limitations, both graft materials demonstrated similar biocompatibility and osteoconductivity in the maxillary sinus augmentation. PMID: 30521656 [PubMed - as supplied by publisher]
CONCLUSION: This study demonstrated that morphologic, elemental, and biochemical modifications of periimplant bone can be studied using micro-ATR FTIR, SEM-EDS, and micro-CT. The complement of these techniques can be considered a new multipurpose approach to investigate bone affected by peri-implantitis. PMID: 30521655 [PubMed - as supplied by publisher]
This study aimed to investigate the in vitro and in vivo bone-forming potential of a sandblasted, large-grit, acid-etched (SLA) titanium (Ti) surface treated with a laminin-derived functional peptide, PPFEGCIWN (DN3). MATERIALS AND METHODS: Human osteoblast-like MG63 cells were cultured with SLA Ti discs untreated or treated with DN3 or a control scrambled peptide (SP). Cell adhesion, spreading, and viability on the discs were tested. Alkaline phosphatase gene expression and enzyme activity were also evaluated. Four DN3-coated SLA Ti implants and four untreated implants were placed into the tibiae of two rabbits (two i...
DISCUSSION: In maxillary sinus floor elevations performed by the lateral approach, the size of the antrostomy did not affect the clinical and radiographic outcomes. PMID: 30521653 [PubMed - as supplied by publisher]
