A case of a bilateral accessory digastric muscle

Abnormalities of the anterior belly of the digastric muscle are rare but have received increased attention by radiologists in recent years in an attempt to avoid confusion with submental cysts or enlarged submental lymph nodes on CT or MR images. We present a case of bilateral accessory digastric muscles which fuse (partially) with the midline raphe of the mylohyoid muscle. Fibres from the right accessory anterior digastric muscle proceeded to decussate and join the mylohyoid muscle and the contralateral insertion of the digastric muscle. Embryological development and possible clinical consequences are discussed

EAO summer camp: a facilitated sharing experience.

Aim: The purpose of the EAO summer camp was to create visions and ideas for future developments in the field of implant dentistry. An additional goal was the installation of a young, strong and enduring network for scientific exchange among participants. Summer camp activity: Forty participants younger than 40 years of age, from 16 different European countries, discussed potential future developments of implant dentistry in a professionally moderated workshop. Participants worked in a competitive manner over 3 days in small teams on four topics: future teaching and education, surgery in 2030, prosthetics in 2030 and futuristic tissue development related to the field of implantology. Various innovative conference and moderation techniques were applied to achieve a maximum output from the creative potential present. Results: Plenum consensus was obtained for several key factors potentially influencing future development in implant dentistry. In particular, teaching and education will be improved by the establishment of curriculum standards and novel teaching technologies. Surgery in 2030 will benefit from an improved cost-effectiveness of new technologies and biomaterials. A more comprehensive knowledge on host susceptibility will have an impact on treatment planning and the predictability of implant therapy. A virtual patient concept and tissue engineering will influence Prosthodontics in 2030. Futuristic tissue development will set a "platinum standard" for tissue regeneration. Summary: Visions on all four topics were generated and discussed intensively during the conference. "Future teaching and education" was voted unanimously as the winning team based on the presented ideas and the special interest this topic generated.

Digital technologies to support planning, treatment, and fabrication processes and outcome assessments in implant dentistry. Summary and consensus statements. The 4th EAO consensus conference 2015

OBJECTIVE The aim of this multicenter randomized controlled clinical trial was to test posterior zirconia-ceramic fixed dental prostheses (FDPs) veneered with a computer-aided design/computer- assisted manufacture (CAD/CAM) lithium disilicate veneering ceramic (CAD-on) and manually layered zirconia veneering ceram OBJECTIVE The task of this working group was to assess the existing knowledge in computer-assisted implant planning and placement, fabrication of reconstructions applying computers compared to traditional fabrication, and assessments of treatment outcomes using novel imaging techniques. MATERIAL AND METHODS Three reviews were available for assessing the current literature and provided the basis for the discussions and the consensus report. One review dealt with the use of computers to plan implant therapy and to place implants in partially and fully edentulous patients. A second one focused on novel techniques and methods to assess treatment outcomes and the third compared CAD/CAM-fabricated reconstructions to conventionally fabricated ones. RESULTS The consensus statements, the clinical recommendations, and the implications for research, all of them after approval by the plenum of the consensus conference, are described in this article. The three articles by Vercruyssen et al., Patzelt & Kohal, and Benic et al. are presented separately as part of the supplement of this consensus conference.ic with respect to survival of the FDPs, and technical and biologic outcomes. METHOD AND MATERIALS Sixty patients in need of one posterior three-unit FDP were included. The zirconia frameworks were produced with a CAD/CAM system (Cerec inLab 3D/Cerec inEOS inLab). Thirty FDPs were veneered with a CAD/CAM lithium disilicate veneering ceramic (Cad-on) (test) and 30 were veneered with a layered zirconia veneering ceramic (control). For the clinical evaluation at baseline, 6, and 12 months, the United States Public Health Service (USPHS) criteria were used. The biologic outcome was judged by comparing the plaque control record (PCR), bleeding on probing (BOP), and probing pocket depth (PPD). Data were statistically analyzed. RESULTS Fifty-six patients were examined at a mean follow-up of 13.9 months. At the 1-year follow-up the survival rate was 100% in the test and in the control group. No significant differences of the technical outcomes occurred. Major chipping occurred in the control group (n = 3) and predominantly minor chipping in the test group (minor n = 2, major n = 1). No biologic problems or differences were found. CONCLUSIONS Both types of zirconia-ceramic FDPs exhibited very good clinical outcomes without differences between groups. Chipping occurred in both types of FDPs at small amounts, yet the extension of the chippings differed. The test FDPs predominantly exhibited minor chipping, the control FDPs major chipping
