Definitions
- the present invention relates to an X-ray film holder of the type stated in the introduction of claim 1.
- a film holder for X-ray photography of teeth is known from USA patent No. 3.003.062.
- This holder comprises a ring to be placed on the drawtube of the X-ray apparatus, and carries on a laterally extending arm a slidable bar, possibly bent, having a supporting and holding plate for an X-ray film secured at its end, thereby maintaining said film at right angles to the axis of the drawtube.
- radiographs can in any case be made at two different angles, namely 90 and 105 .
- Such a system of holders can be used for most patients, b particularly in case of radiography of molars, a special structure of the jaws of certain patients or a particular path of the roots of a tooth can result in X-ray pictures no use to the dentist when determining the position of th condition that may require treatment, or diagnosing a pos sibly sick condition.
- the object of this invention is to indicate a holder of t type mentioned in the introduction of claim 1, said holde being universally applicable.
- the plate holder may be secured in a desire position implies that the angle formed by the plate holde and the pencil of rays radiating from the drawtube of the X-ray apparatus makes it possible always to adjust the pl holder so that the bisector between the part of the tooth be radiographed and the X-ray film placed on the holder is positioned at right angles to the pencil of rays, irrespective of the structure of the patient's oral cavity, and irrespective of the path taken by a tooth root.
- the plate holder is made as stated in claim 2.
- the plate holder according to this em ⁇ bodiment, can be used when producing radiographs both of the right part and of the left part of the oral cavity.
- the plate holder is de ⁇ signed as stated in claim 3. This embodiment makes it possible .to apply one plate holder for making radiographs of the front portions both of the upper part of the mouth and the lower part of the mouth.
- fig. 1 shows one embodiment
- fig. 2 shows another embodiment of the holder according to the invention
- fig. 3 shows the plate holder applied in case of the embodi- ment according to fig. 1
- fig. 4 is a sectional view of the slidable bar of the holder.
- 1 is a ring member to be placed on the drawtube of an X-ray tube.
- 2 is an arm extending from said ring, in which arm a cylindrical tube 3 is situated and slidable in said arm 2 and capable of being secured in a required posi ⁇ tion by means of a tightening screw 4.
- the tube 3 ends in a transverse tube portion 5, in which a rotatable rod 6 is placed carrying a plate holder 7.
- a spindle 8 is placed, which at the free end of the tube has a thread 9 engaging an internal thread 10 in the tube 3.
- the spindle 8 is turned by means of a knob 11, and at its opposite end 12 it is tapered so that it may be pressed down into a 13 in the rod 6 .
- means 14 are provided for securing the envelope which contains the X-ray film i tended for the requested radiograph.
- rod 6 is fastened at one of the lateral edges of the plate holder.
- a supporting part 15 extending perpend cularly to the plate holder is placed between said plate holder 7 and the rod 6.

Abstract
Dans un support de film rayons X utilise dans la radiographie dentaire, et du type comprenant un anneau (1) destine a etre monte sur un tube a rayons X, lequel anneau porte un bras ou tube coulissant (3) qui porte a son extremite libre un porte-plaque (7 ou 7') pour un film a rayons X, le porte-plaque est fixe a une tige (6) soit directement soit a l'aide d'une piece de support (15), l'extremite de cette tige etant noyee dans une partie tubulaire (5) s'etendant depuis le bras ou tube (3), et de plus, dans la barre tubulaire (3) creuse, un axe (8) est loge dont l'extremite peut etre serree contre la tige (6). De cette maniere, on obtient un porte-plaque qui peut etre ajuste suivant n'importe quel angle par rapport aux rayons des faisceaux provenant du tube a rayons X.In an X-ray film support used in dental radiography, and of the type comprising a ring (1) intended to be mounted on an a plate holder (7 or 7') for an X-ray film, the plate holder is fixed to a rod (6) either directly or using a support piece (15), the end of this rod being embedded in a tubular part (5) extending from the arm or tube (3), and moreover, in the hollow tubular bar (3), an axis (8) is housed, the end of which can be tightened against the rod (6). In this way, a plate holder is obtained which can be adjusted at any angle to the rays of the beams coming from the X-ray tube.
