This paper describes a new technique for the closure of oro-antral fistula/communication, in which both hard tissue (bone) and soft tissue closure is achieved. The sandwich technique utilizes a suitable bone grafting material sandwiched between two sheaths of Biogide (a resorbable membrane) for the hard tissue closure of oro-antral communication post traumatic exodontia. The bone grafting mater...

The aim of the present study was to evaluate the biocompatibility of differently cross-linked collagen membranes in cultures of human PDL fibroblasts and human osteoblast-like cells. Four collagen membranes [BioGide (BG), BioMend (BM), Ossix (OS) and TutoDent (TD)] were tested. Cells plated on culture dishes (CD) served as positive controls. Six specimens of each membrane were incubated with (1...

AIM To investigate collagen patches seeded with mesenchymal stem cells (MSCs) and/or tenocytes (TCs) with regards to their suitability for anterior cruciate ligament (ACL) repair. METHODS Dynamic intraligamentary stabilization utilizes a dynamic screw system to keep ACL remnants in place and promote biological healing, supplemented by collagen patches. How these scaffolds interact with cells ...

Human dental pulp stem cells (hDPSCs), selected from the stromal-vascular fraction of dental pulp, are ecto-mesenchymal stem cells deriving from neural crests, successfully used in human bone tissue engineering. For their use in human therapy GMP procedures are required. For instance, the use of fetal bovine serum (FBS) is strongly discouraged in clinical practice due to its high risk of prions...

Arma biliminde, büyük bir kalkanın içindeki aynı nişanı taşıyan daha küçük kalkanı tarif etmek için kullanılan “mise en abyme”in kelime anlamı “sonsuz uçuruma koymak”tır. Mise abyme’i, hanedan armalarının görsel düzenlenişindeki yansıma ve derinlik etkisinden ilham alarak edebiyata kazandıran André Gide, kavramın çerçevesini “resim içinde resim” “oyun oyun” gibi farklı bağlamlarla genişletmiş, ...

Fair play; sporda yardımlaşma, fırsat eşitliğini sağlama, saygı, dürüstlük gibi davranışlarda kendini göstermektedir. Sporda amaç oyunu kurallarına göre oynamaktır ve esas olan oyunun hem yazılı de olmayan bağlı kalmaktır. Buradan karşımıza fair playin formal informal yönü çıkmaktadır. Formal play, kendine ait uygun davranışı alırken; play yani gelenekler, görenekler, toplumsal normlara davranı...

OBJECTIVE Lateral ridge augmentations are traditionally performed using autogenous bone grafts to support membranes for guided bone regeneration (GBR). The bone-harvesting procedure, however, is accompanied by considerable patient morbidity. AIM The aim of the present study was to test whether or not resorbable membranes and bone substitutes will lead to successful horizontal ridge augmentati...
