J Craniomaxillofac Surg 2019 Mar 25. Epub 2019 Mar 25.

Department of Otorhinolaryngology - Head and Neck Surgery, University of Helsinki and HUS Helsinki University Hospital, Helsinki, Finland; Division of Ear, Nose and Throat Diseases, Department of Clinical Sciences, Intervention and Technology, Karolinska Institutet, Karolinska University Hospital, Stockholm, Sweden; Research Programme in Systems Oncology, Faculty of Medicine, University of Helsinki, Helsinki, Finland. Electronic address:

Background: Osteosarcomas (OS) in the craniomaxillofacial (CMF) region are typically diagnosed at later age than long-bone OS, but they are reported to have better 5-year survival. Curative treatment warrants wide surgical resection, which is often not possible in the CMF region. The purpose of this article is to present a nationwide series of CMF in Finland to discuss the role of surgery. Read More

Accuracy of patient-specific implants and additive-manufactured surgical splints in orthognathic surgery - A three-dimensional retrospective study.

J Craniomaxillofac Surg 2019 Mar 2. Epub 2019 Mar 2.

University of Heidelberg, Department of Oral and Maxillofacial Surgery, (Head of Department: Prof. Dr. Dr. J. Hoffmann), Im Neuenheimer Feld 400, D-69120, Heidelberg, Germany.

Introduction: Because of the many limitations of conventional surgery planning for the treatment of orthognathic deformities, as well as advancements in computer-assisted planning, there is an urgent need for technical devices that transfer the surgical plan into the operating theatre. In this regard, additive-manufactured, patient-specific implants (PSI) and additive-manufactured interocclusal splints represent promising approaches. The aim of this retrospective study was to compare the accuracy of these two devices, with regard to preoperative virtual treatment planning for maxillary Le-Fort I advancement surgery using IPS CaseDesigner, and based on a new analysis method without the use of landmarks.

Cranioplasty with patient-specific implants in repeatedly reconstructed cases.

J Craniomaxillofac Surg 2019 May 14;47(5):709-714. Epub 2019 Feb 14.

Department of Cranio-Maxillofacial Surgery, Maastricht University Medical Center, PO Box 5800, 6202 AZ, Maastricht, the Netherlands.

Objective: Cranioplasty is indicated to restore form and function of bone defects of the neurocranium. Autografts are the gold standard, alloplastic materials are used when autologous bone is unavailable or unsuitable, and increasing evidence supports the use of patient-specific implants (PSIs) for reconstruction. We reviewed our own patient data to assess pre- and intraoperative aspects, complications and costs in patients that were treated with PSIs from titanium or polyetheretherketone (PEEK) for skull bone reconstruction.

Enhancing adhesion and alignment of human gingival fibroblasts on dental implants.

J Craniomaxillofac Surg 2019 Apr 21;47(4):661-667. Epub 2019 Feb 21.

Department of Prosthetic Dentistry and Dental Materials Sciences, Saarland University, Homburg, Saar, Germany. Electronic address:

Background: Promoting the directional attachment of gingiva to the dental implant leads to the formation of tight connective tissue which acts as a seal against the penetration of oral bacteria. Such a directional growth is mostly governed by the surface texture.

Material And Methods: In this study, three different methods, mechanical structuring, chemical etching and laser treatment, have been explored for their applicability in promoting cellular attachment and alignment of human primary gingival fibroblasts (HGFIBs). Read More

A new multilayered membrane for tissue engineering of oral hard- and soft tissue by means of melt electrospinning writing and film casting - An in vitro study.

J Craniomaxillofac Surg 2019 Apr 4;47(4):695-703. Epub 2019 Feb 4.

Department of Oral and Maxillofacial Plastic Surgery, (Head: Prof. Dr. Dr. Alexander C. Kübler), University Hospital Würzburg, Pleicherwall 2, 97080 Würzburg, Germany; Interdisciplinary Center for Clinical Research, University Hospital Würzburg, Josef-Schneider-Straße 2, 97070 Würzburg, Germany.

Membranes that form a mechanical barrier not only for cells but also for the bacterial flora of the oral cavity may be helpful in infection-free wound healing for guided tissue regeneration (GTR) applications in the field of oral- and maxillofacial surgery. Controlled wound healing without interference from bacterial contamination appears to be achievable in combination with surface scaffolds for bone- and soft tissue regeneration. As this has not yet been realized, we developed multilayered membranes in this study consisting of specific surface scaffolds for bone- and mucosal regeneration as well as bacteria-tight core membranes.
