The purpose of this study is to evaluate the intra- and post-operative performance and safety of direct three dimensional printing 3DP porous polyethylene implants in cranial reconstruction. Prefabricated porous polyethylene implants were prepared by direct 3DP, and cranioplasty implantation was performed.

Removal of a large cranial tumour and reconstruction of the consequent bone defect in the same surgical setting is an ordinary procedure.

Cranioplasty using custom-made hydroxyapatite versus titanium: a randomized clinical trial

Custom implants for the reconstruction of craniofacial defects have gained importance due to better performance over their generic counterparts. This is due to the precise adaptation to the region of implantation, reduced surgical times and better cosmesis. Application of 3D modeling in craniofacial surgery is changing the way surgeons are planning surgeries and graphic designers are designing custom implants. Advances in manufacturing processes and ushering of additive manufacturing for direct production of implants has eliminated the constraints of shape, size and internal structure and mechanical properties making it possible for the fabrication of implants that conform to the physical and mechanical requirements of the region of implantation. This article will review recent trends in 3D modeling and custom implants in craniofacial reconstruction. Reconstruction of the craniofacial skeleton is extremely challenging even to the most experienced surgeon.

The principal advantages of such materialsare the possibility of customising and pre-manufacturing theimplant pre-operatively, improved biocompatibility, biomimeticbehaviourwhichacts likeboneonce implantedandosteointegrationwith the host bone Staffa et al. Results: Fifty one patients were followed-up, no rejection occurred and only one case of infection wasrecorded. Five patients had minor surgery-related complications, and no spontaneous implant fracturesor mobilisation were reported.

Custom made bioceramic implants in complex and large cranial reconstruction: A two-year follow-up

Correspondence Address : Dr. Custom-made cranial implants facilitate the surgical reconstruction of destructive pathologies of the skull or extensive demolitive skull surgery. Customized cranioplasty allows for an immediate restoration of the functional integrity of the cranial defect restitutio ad integrum , with excellent functional and esthetic outcome and a quick, safe, and simple procedure. In this context, bioceramics like hydroxyapatite HA claim high biocompatibility and bone-binding capability.

Cranial implants are used as a substitute for parts of cranial bones that lost its function due to trauma or disease. An important factor, that influences function of the cranial implant structure, is its mechanical behavior. This thesis briefly summarizes current knowledge in the field of cranial defect reconstruction and provides comparison of different types of materials and implant wall shapes, based on stress-strain analysis of Computer Tomography based neurocranial model with placed implant and loaded by intracranial pressure and external load.

3D modeling, custom implants and its future perspectives in craniofacial surgery

О кольце он позаботиться не успел, слова пришли сами. Именно это и нравилось ей в нем - спонтанность решений.

У меня есть доказательство! - Сьюзан встала и подошла к терминалам.  - Помнишь, как ты отключил Следопыта? - спросила она, подойдя к своему терминалу.  - Я снова его запустила.

Он медленно потянул к себе микрофон. В то же самое мгновение Сьюзан опять бросила взгляд на руку Танкадо, на этот раз посмотрев не на кольцо… не на гравировку на золоте, а на… его пальцы. Три пальца. Дело было вовсе не и кольце, a в человеческой плоти.

В воздухе ощущался едва уловимый запах озона. Остановившись у края люка, Сьюзан посмотрела. Фреоновые вентиляторы с урчанием наполняли подсобку красным туманом.
