Implant prosthetic rehabilitation in partially edentulous patients with bone atrophy. An umbrella review based on systematic reviews of randomised controlled trials.

Eur J Oral Implantol. 2018;11(3):261-280.



To summarise systematic reviews that assess the effects of different interventions for implant prosthetic rehabilitation in partially edentulous patients with the presence of bone atrophy.


Only systematic reviews of randomised controlled trials (RCTs) dealing with partially edentulous adult patients presenting bone defects were included. Treatments of interest were bone augmentation procedures, use of short, tilted or zygomatic implants, sinus lift and transposition of the inferior alveolar nerve. Outcome variables considered were: prosthetic and implant failure, complications, radiological and clinical peri-implant bone level variation, aesthetic and functional satisfaction, and vestibular peri-implant soft tissue recession. A search of systematic reviews of RCTs selected from MEDLINE, the Cochrane Database of Systematic Review, and the Prospero register published in the past 5 years (May 2012 – May 2017) was performed. Systematic reviews were also manually searched. Independent data extraction by two authors using predefined data fields, including ROBIS risk of bias, was executed.


A total of 12 systematic reviews of RCTs were identified for inclusion in the overview. Eight reviews were considered at low risk of bias. Short implants (≤ 8 mm) were associated with a notable decrease in complications compared to long implants with bone augmentation procedures. Many trials compared different sinus lift procedures and different bone augmentation techniques. None of these indicated that one procedure could reduce prosthetic or implant failures when compared to the other. The use of a membrane can contribute to the regeneration of the hard tissue in horizontal augmentation. Different membranes or bone substitutes did not give substantially different results. No data are available regarding comparisons involving zygomatic implants or tilted implants or transposition of the alveolar nerve.


Overall, the evidence is not sufficiently robust to determine the best treatment for implant prosthetic rehabilitation in partially edentulous patients presenting bone atrophy. In terms of vertical defects, if the short implants can be used they should be used because the number of complications are reduced compared to longer implants with sinus lift or bone augmentation. Nevertheless, caution should be exercised because long-term follow-up studies were not available. No conclusions can be drawn regarding the comparison between different vertical bone augmentation techniques in atrophic posterior mandible because quantitative meta-analyses were not performed. With regards to horizontal defects, the use of a membrane appears to increase the regeneration of the hard tissue but no differences were detected in prosthesis or implant failures or in complications.

New oral hygiene care regimen reduces postoperative oral bacteria count and number of days with elevated fever in ICU patients with esophageal cancer.

J Oral Sci. 2018 Aug 30. doi: 10.2334/josnusd.17-0381. [Epub ahead of print]


Using a controlled pre/post study design, we investigated the effects of professional mechanical cleaning of the oral cavity with benzethonium chloride, interdental brushes, and hydrogen peroxide on the number of oral bacteria and postoperative complications among esophageal cancer patients in an intensive care unit. Before surgery, 44 patients with esophageal cancer were recruited at Okayama Hospital from January through August 2015. The control group (n = 23) received routine oral hygiene care in the intensive care unit. The intervention group (n = 21) received intensive interdental cleaning with benzethonium chloride solution and tongue cleaning with hydrogen peroxide. The number of oral bacteria on the tongue surface and plaque index were significantly lower in the intervention group than in the control group on postoperative days 1 and 2 (P < 0.05). Additionally, the number of days with elevated fever during a 1-week period was significantly lower in the intervention group than in the control group (P = 0.037). As compared with routine oral hygiene, a new oral hygiene regimen comprising benzethonium chloride, interdental brushes, and hydrogen peroxide significantly reduced the number of oral bacteria and days with elevated fever in patients with esophageal cancer.

Dentsply Sirona World 2018 proves again to be the dental industry’s must- attend educational event

Unmatched education, cutting-edge technologies and products, plus nonstop entertainment left attendees motivated by what they learned and excited to come again next year 

CHARLOTTE, NC (Sept. 19, 2018) – As three days of unparalleled educational opportunities and thrilling entertainment options came to a close, attendees left the Rosen Shingle Creek Resort in Orlando understanding why Dentsply Sirona World remains the premier dental event in the world. 

“With more than 100 Breakout Sessions, rousing General Sessions, top-tier entertainment and lively social activities, Dentsply Sirona World proved why there is no equal to the Ultimate Dental Meeting,” said Vice President of Marketing Ingo Zimmer.

Held Sept. 13-15, attendees filled enlightening education sessions taught by the biggest names in dentistry, got hands- on with the most innovative technologies and products on the trade show floor, experienced once-in-a-lifetime private shows from singer Katy Perry and comedian Jim Gaffigan and so much more! 

Continuing educational courses were offered in 12 specialized tracks, a record for the event. Attendees had no shortage of incredibly high-quality learning opportunities when they personalized their schedules to meet their needs.

The General Sessions kept attendees on the edge of their seats with inspiring speakers, including Dr. Dan Butterman, Dr. Stephen Sterlitz, Heidi Arndt, Jennifer Chevalier and Brian McCarthy. Additionally, Dr. Ross Enfinger performed a live dental procedure.

Per usual, Dentsply Sirona World offered its guests the chance to experience celebrity entertainment in a personal setting. Pulitzer Prize-winning author and New York Times best seller Doris Kearns Goodwin captivated the audience with her

keynote address, sponsored by Implant Seminars, while Grammy-nominated comedian Jim Gaffigan kept them laughing with his standup and you could really hear the crowd ROAR during global pop superstar Katy Perry’s private concert.

Two wellness activities allowed attendees to better both their minds and bodies, as Compassionate Finance sponsored both a medieval fun run and a yoga class. Attendees were in a jovial mood wearing their best medieval-inspired costumes, as they made their way along the Rosen Shingle’s beautiful championship golf course during Friday morning’s fun run. On Saturday, guests looked inward and found their Zen during the Yoga Mix! Modern Twist on Yoga class.
The Oktoberfest gathering was the perfect end to an amazing three days in Orlando. Guests put on their lederhosen or dirndls and hit the dance floor to socialize with their peers. From the rousing Bavarian band, to the scrumptious food to the tasty drinks, this party captured the true spirit of the German festival.

Oral antiseptics and nickel–titanium alloys: mechanical and chemical effects of interaction

The effect of oral antiseptics on the corrosion of nickel–titanium (NiTi) alloys with various coating was investigated. Uncoated, titanium nitride-coated and rhodium-coated NiTi archwires (0.020 × 0.020″) were tested in interaction with artificial saliva pH 4.8 and oral antiseptics based on hyaluronic acid (Gengigel), chlorhexidine (Curasept) and essential oils in alcohol base (Listerine). The dynamics of nickel and titanium ions release were recorded during 28 days. Springback ratio and modulus of resilience were assessed by three-point bending test. The results showed that corrosion of NiTi is related to type of antiseptic mouth rinse and coating formulations. Exposure to an artificial saliva and antiseptics tend to reduce flexibility and resilience of NiTi archwires. The influence of the media is more significant than the influence of the type of the alloys coating. The largest release of nickel ions is in the first 3 days. Antiseptics do not cause further deterioration of the elastic properties in uncoated NiTi compared to saliva. As a result of exposure of nitrified NiTi wires in Listerine, there is bigger release of nickel ions, decrease in elastic properties and lower force delivery in unload. Listerine tends to reduce elastic properties of rhodium-coated wires also. In conclusion, except for Listerine, changes of mechanical characteristics induced by antiseptics are small and would not have a clinically important impact. Generally, Curasept would be the most suitable option.
