Title: The calcification of the Falx cerebri as a pathognomonic sign in Gorlin-Goltz syndrome

Summary: The origin of the peculiar radiological appearance, named "plurilaminar" of the Falx cerebri in patients with the syndrome is shown, review of 10,000 X-rays from the archive and literature review.

Title: A new class of material in dentistry

Summary: Polyetheretherketone (PEEK) has been used for years in industry and medicine. For the first time, its use as a structural material in implant-supported bridges is described.

Language: German.

Title: Polyetheretherketone (PEEK) - a novel material for prosthetic structures, part 1

Summary: Two clinical cases of implant-supported bridges composed of prefabricated parts and the individual PEEK structure by injection are described.

Language: German.

Title: Polyetheretherketone (PEEK) - a novel material for prosthetic structures, part 2

Summary: The fabrication of the individual PEEK structure by CAD/CAM is presented, comparing the long-term results.

Language: German.

Siewert B regarding a case

Title: PEEK a "new" material for metal-free prosthetic therapy

Summary: The solution of a difficult case from beginning to end is described using PEEK for the elaboration of a milled bar with overdenture and a fixed bridge, both implant-supported.

Language: German.

Siewert B regarding a case

Title: Implant-supported bridge in combination with natural pieces as a therapeutic option

Summary: Protocol of a treatment in an almost edentulous patient by means of a combined bridge of teeth and implants in a single piece with telescopic zirconium crowns and a whole PEEK structure.

Language: German.

Siewert B regarding a case

Title: Fabrication of implant-supported bridges by CAD/CAM from PEEK discs - New indications for latest generation polymers.

Summary: A case of guided surgery (insertion of 4 implants in the lower jaw in a minimally invasive way) and the manufacturing steps of a 12-piece bridge on 4 implants with the F&F system (all-on-four) with the PEEK structure by mechanized milling is presented.

Language: German.

Title: The clinically relevant advantages of PEEK (Polyetheretherketone) in dental prosthetics.

Summary: The extraordinary advantages of PEEK such as biocompatibility, resistance to torsion, fatigue, elasticity, specific weight, tribological properties and being metal-free are shown with clinical examples.

Language: German.

Title: Implant-supported rehabilitation with milled bars - Application of PEEK by CAD/CAM.

Summary: In a clinical case, the manufacturing process of a hybrid prosthesis with milled bars and overdenture using the polyetheretherketone polymer is shown, explaining the steps in the clinic and the dental laboratory.

Language: Spanish.

Title: Key factors for long-term success with high-performance Juvora implant-supported prostheses.

Summary: 21 all-on-four type bridges with a PEEK structure screwed onto implants have been clinically evaluated with a maximum time of 8 years and 9 months and a minimum observation time of 1 year and 2 months.

Language: English.

Title: Survival and treatment success of full-arch implant-supported bridges with PEEK structure.

Summary: 5-year retrospective clinical study: The 20 examined bridges with PEEK structure show a better result compared to conventional rehabilitations described in the literature regarding peri-implant bone, cases of peri-implantitis, mechanical failures of the bridge itself and patient satisfaction.

Language: English.
