Dear Colleagues,

Resorbable and nonresorbable materials have been used to repair defects in a clinical setting, which has led to the development of a wide variety of materials for specific therapeutic purposes. The efficiency in the repair of the defect and the safety of the different used materials are determined not only by the anatomical site where they are located but also by the nature and structure of their components. These materials range from natural polymers and materials of biological origin which are designed to be resorbed inside the body, to metallic and synthetic materials which need to be removed after their function is served. Their importance is essential for other elements, such as the composition of different bone substitutes that can be used which can be either derived from biological products such as demineralized bone matrix, platelet-rich plasma, adjunction of growth factors or synthetic such as calcium sulfate, tri-calcium phosphate ceramics, or polymer-based substitutes. These substitutes must be chosen selectively depending on their clinical use which include but are not limited to spine fusion, open-wedge tibial osteotomy, long bone fracture, oral and maxillofacial surgery, or periodontal treatments.

This Special Issue is dedicated to any resorbable and non-resorbable material which is used for medical applications and where the use of these elements is key in accelerating the healing process and repairing damage and defects.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
