3D Printing of Bone Grafts for Cleft Alveolar Osteoplasty - Evaluation in a Preclinical Model.

Front Bioeng Biotechnol 2020 25;8:217. Epub 2020 Mar 25.

Centre for Translational Bone, Joint and Soft Tissue Research, University Hospital "Carl Gustav Carus", Faculty of Medicine, Technische Universität Dresden, Dresden, Germany.

One of the most common hereditary craniofacial anomalies in humans are cleft lip and cleft alveolar bone with or without cleft palate. Current clinical practice, the augmentation of the persisting alveolar bone defect by using autologous bone grafts, has considerable disadvantages motivating to an intensive search for alternatives. We developed a novel therapy concept based on 3D printing of biodegradable calcium phosphate-based materials and integration of osteogenic cells allowing fabrication of patient-specific, tissue-engineered bone grafts.

"ABCD" Implant Classification: A Comprehensive Philosophy for Treatment Planning in Completely Edentulous Arches.

J Oral Implantol 2020 Apr;46(2):93-99

Private practice, Thane West, Maharashtra, India.

A thorough and precise treatment plan that considers various factors such as age, availability of bone, interarch space for prosthesis design, smile line, lip support, patient desires, and economics is a necessity before implant surgery. Many previous classification systems for treatment planning in edentulous situations tend to focus on only a certain parameter such as esthetics, or available bone volume, or are specifically designed for the maxilla or mandible. The authors have proposed a simplified and universal ABCD classification that uses the 4 vital parameters of age, bone volume, cosmetic display, and degree of resorption to create an algorithm that satisfies the treatment needs of every patient.

Korean J Orthod 2019 May 21;49(3):194-201. Epub 2019 May 21.

Department of Orthodontics, School of Dentistry, Seoul National University, Seoul, Korea.

When a patient shows severe crowding, premolar extraction should be considered to provide required available space for alignment. If the third molars have already erupted and demonstrate a poor prognosis, third molar extraction and distalization of the posterior dentition can be used instead of premolar extraction to obtain space. Interproximal stripping (IPS) may also be used to gain space in cases of crowding. Read More

Current approaches to cleft lip revision.

Curr Opin Otolaryngol Head Neck Surg 2019 Aug;27(4):287-293

Division of Plastic and Reconstructive Surgery, London Health Sciences Centre, Victoria Hospital Campus, London, Ontario, Canada.

Purpose Of Review: Cleft lip repair requires multidisciplinary follow-up throughout a child's life and often requires lip revision surgery in adolescence to restore function and symmetry of the lip. There is significant variability in the approaches taken for lip repair and therefore a review of current techniques and subsequent guidance to secondary cleft lip repair is warranted.

Recent Findings: New methods of secondary reconstruction can be divided into superficial or muscle related. Read More

Department of Mechanical Engineering, Penn State University, University Park, PA, United States. Electronic address:

The success of dental implant treatment is related to the complex 3-dimensional (3D) biomechanics of the implant-bone interaction. In this work, 3D numerical models are built based on micro X-ray computed tomography (micro-CT) images of a cadaveric mandible specimen with implants placed in it. The simulation results show that the computed strain values in bone are sensitive to the uncertainties in trabecular tissue modulus and fairly insensitive to the modulus of implants and teeth and the detailed geometry of the fixed boundary condition.

Vascularized Combined with Nonvascularized Fibula Flap for Mandibular Reconstruction: Preliminary Results of a Novel Technique.

J Craniofac Surg 2019 Jun;30(4):e365-e369

Department of Oral and Maxillofacial Surgery, Peking University Shenzhen Hospital, Shenzhen, China.

Background: Repair of long-span mandibular defects with vascularized free fibular grafts is now a routine procedure. Vertical discrepancy between a graft segment and the occlusal plane can be resolved through several options, including delayed onlay bone graft, iliac bone reconstruction, fibula distraction, and double-barrel fibula flap grafts. The present study (level of evidence: level IV, case series) introduces a new method for mandibular augmentation, wherein a vascularized fibular segment was used to simulate the superior alveolar ridge of the neomandible, whereas a nonvascularized fibular segment was used to reconstruct the inferior border.

Review of Risk Assessment of Major Anatomical Variations in Clinical Dentistry: Accessory Foramina of the Mandible.

Clin Anat 2019 Jul 20;32(5):672-677. Epub 2019 Mar 20.

Seattle Science Foundation, Seattle, Washington.

Most of the studies of the mandible's anatomical variations have presented the authors' speculations, and only a limited number has provided evidence that demonstrated the actual complications injury to the variant structures caused. To our knowledge, no study has evaluated the risks associated with these variant anatomical structures' injury. We reviewed articles that described clinical cases of the injury to, and anatomical studies of, three anatomical variants of the mandible-the accessory mental, lingual, and retromolar foramina-with which dentists are relatively familiar and that are mentioned often in the context of implant and third molar surgeries, to describe risk assessment methods with which to evaluate potential complications preoperatively.

Refined Approach to Preservation of the Inferior Alveolar Nerve during Resection and Primary Reconstruction of the Mandible.

Craniomaxillofac Trauma Reconstr 2019 Mar 28;12(1):34-38. Epub 2018 Mar 28.

Department of Reconstructive Surgery, The Main Military Burdenko Hospital, Moscow, Russia.

Sacrifice of the inferior alveolar nerve (IAN) during resection of the mandible is taken as a rule. In 1987, Jensen and Nock described a technique that permitted placement of dental implants in the atrophied mandibular alveolar ridge that lacked sufficient vertical height superior to the mandibular canal. This technique was used by some authors to preserve continuity of the IAN during resection of the mandible in patients with benign tumors. Read More

Cued Speech Enhances Speech-in-Noise Perception.

J Deaf Stud Deaf Educ 2019 07;24(3):223-233

GIPSA-lab, Univ. Grenoble Alpes, CNRS, Grenoble INP.

Speech perception in noise remains challenging for Deaf/Hard of Hearing people (D/HH), even fitted with hearing aids or cochlear implants. The perception of sentences in noise by 20 implanted or aided D/HH subjects mastering Cued Speech (CS), a system of hand gestures complementing lip movements, was compared with the perception of 15 typically hearing (TH) controls in three conditions: audio only, audiovisual, and audiovisual + CS. Similar audiovisual scores were obtained for signal-to-noise ratios (SNRs) 11 dB higher in D/HH participants compared with TH ones. Read More
