Abstract: A medical device comprising a substantially flexible porous structure. The porous structure comprises a plurality of interlocking units. Each of the plurality of interlocking units comprises a body and at least one arm. The plurality of interlocking units is configured to have space between adjacent interlocking units when the porous structure is in a neutral configuration. The plurality of interlocking units is configured to contact the respective body and arm of adjacent interlocking units when a compressive force is applied to the porous structure, thereby restricting compression of the porous structure. The plurality of interlocking units is configured to contact the respective arms of adjacent interlocking units when an extension force is applied to the porous structure, thereby restricting extension of the porous structure.

Abstract: An implant and guide are described, together with methods for configuring the same. The implant and guide are for maxillofacial osteosynthesis and may be provided as a kit. Three-dimensional models of the pre- and post-operative anatomy are used to define attachment points. These attachment points are used to define a structure for the implant and the guide.

Abstract: Disclosed is a medical device (9) comprising a porous structure (1), wherein a configuration of the porous structure (1) varies in dependence on a load applied to the porous structure (1), such that the porous structure (1) has a first configuration when the load is of a first magnitude, and has a second configuration when the load is of a second magnitude greater than the first magnitude. The porous structure (1) comprises a first surface portion (2) and a second surface portion (3). The first surface portion (2) is disengaged from the second surface portion (3) when the porous structure (1) has the first configuration, and is engaged with the second surface (3) portion when the porous structure (1) has the second configuration.

Abstract: A temporo-mandibular joint prosthesis comprising: a first part for attaching to a temporal bone; a second part for attaching to a mandible bone; and a mechanism linking the first part and the second part. The mechanism defines a range of motion of the first part relative to the second part for when the first and second parts are attached to a temporal bone and a mandible bone, respectively. The mechanism includes a rotary joint providing a rotational range of motion of the first part relative to the second part; and a first slider joint providing a first translational range of motion of the first part relative to the second part.

Abstract: The invention relates to a method for the surface treatment of a biologically inert titanium implant to be placed in contact with a bone of the human body, which involves allowing body fluids, such as the inorganic portion of human blood plasma, to naturally deposit, onto the titanium implant, a calcium phosphate film having the formula Ca5(PO4)3(OH), in the form of hydroxyapatite, with a view to rendering the biologically inert titanium biologically active so as to enable the bone to chemically bond to the implant, thus promoting osseointegration, the method including an operation that involves submerging the titanium in a sodium hydroxide (NaOH) solution, wherein said submersion causes the formation of a film of hydrated titanium oxides (HTiO3—) on the titanium, which in turn causes hydroxyl groups (TiOH) to appear, thus enabling the deposition of said calcium phosphate film.

Abstract: Disclosed embodiments relate to a customized assembly of osteosynthesis plates. The customized assembly of osteosynthesis plates is custom-made, for example I-shaped and/or L-shaped and/or cross-shaped and/or crow's-foot-shaped ones which are themselves customized according to the operation to be carried out and the future anatomy of the patient, characterized in that the osteosynthesis plates are connected together by a rod, the rod further comprising two protrusions (4) protruding from the rod towards the nasal orifice (8) of the patient into positions that correspond to the two ends (5, 6) of the base (7) of the nasal orifice (8) of the patient. The invention can be used during dental occlusion operations, for example.

Abstract: The invention relates to a customized intraoral jaw distractor, of the type that comprises two anchoring means (1, 2) fastened to the mandibular body at two fixed anchor points, located on either side of the osseous callus.

Abstract: The present invention relates to a porous structure having a controlled pattern (1), which is repeated in space, in three dimensions, said porous structure enabling the production of surgical implants for filling in bone defects. According to the invention, said structure is characterized in that said pattern (1) consists of three wings (2) arranged in a star shape, each angle (A) formed between two wings being substantially equal to 120°, each wing having a generally rectangular shape and being hollowed (3) at the center thereof. Each of the three wings (2) of said pattern is advantageously beveled at its free end or tip (4), and the width of the base (5) of each bevel is slightly greater than the thickness of the wings (2) of which it forms an extension.

Abstract: An external bone distractor (1) having a threaded curvilinear rod (4) including several diametrical flat sections (7,8) with the thread (9) of the rod (4) continuing along longitudinal lines. At least a pair of carriages (2) are engaged on the rod and solidly connected to spindle supports (3). Guide members (10, 13) cooperate with the flat sections for preventing rotation of each of the carriages about the axis of the rod. Adjusting devices (14, 15) position each of the carriages along the length of the rod. The curvilinear rod (4) provides for use of the distractor in reconstruction of curved bone segments, such as in the jaw, face and skull.

Abstract: The prosthetic temporomandibular implant (10) comprises a concave surface (16) and a convex surface (17) designed to cooperate, respectively, with the natural outer surface (9) of the condyle (5) and the natural inner surface (7) of the fossa (8) of a damaged joint (2) of a human mandible (1). It is made of a rigid biocompatible material such as ceramic, stainless steel or an aluminum/zirconium alloy. The implant is designed based on an image of the joint (2) generated by a medical imaging system and incorporating an image of a healthy joint (3); these three-dimensional images are processed by a CAD (segmentation, vectorization) system to obtain a vector representation of the implant (10) and a data file capable of controlling a digital milling machine. The invention is applicable to the restoration of a damaged TMJ (2).
