Definitions
- the present invention relates to the field of periodontal treatment instruments and in particular instruments allowing the elimination of tartar simultaneously on the root surface and on the wall of the mucosa in the periodontal pockets.
- the success of periodontal treatments depends largely on the complete removal of tartar which is located in the periodontal pockets.
- the means known to date are, on the one hand, manual curettes or else inserts mounted on vibrating handpieces, in particular ultrasonic scalers. These means have the disadvantages that the rigidity of the instruments does not allow the treatment of deep periodontal pockets as well as the proper cleaning of furcations. This forces the practitioner to practice according to the classic methods of periodontal surgery with cutting of flaps.
- the present invention aims to provide instruments and a method for treating periodontal conditions allowing the treatment of deep periodontal pockets and areas of furcation without having to resort to cutting flaps.
- the invention relates to a periodontal treatment instrument consisting of a handle and a blade, characterized in that said blade has an active part having two sectors, distributed along the blade, and each located on either side other from a plane passing through the axis of the blade, these two sectors having different levels of aggressiveness so that, during the treatment, the instrument being introduced into the periodontal pocket, the most aggressive sector enters contact with the root surface of the tooth and the other less aggressive one comes into contact with the mucosa.
- Said instrument being by means of its handle held on a handpiece, imparting a vibration movement allowing the two sectors to detach the unwanted tartar.
- the dental surgery instrument according to the present invention has the advantage that, once introduced into the periodontal socket, it can reach depths inaccessible to instruments according to the known technique.
- Another advantage offered by the instrument according to the present invention is the fact that during its use, the root surface on the one hand and the mucous wall on the other hand are treated simultaneously.
- FIG. 1 represents a side elevation view of the instrument
- FIG. 2 represents a side elevation view, on the side opposite to that of FIG. 1,
- FIG. 3 represents an enlarged sectional view along the line A-A 'of FIG. 2, and
- FIG. 4 shows a side elevation view of a second embodiment of the instrument
- FIG. 5 shows a perspective view of a variant of the invention
- the dental surgery instrument consists essentially of a blade (1) having a substantially elliptical section, and having on its side a plurality of mutually adjacent projections which give it the desired roughness.
- These projections are arranged on parallel lines (2,2 ′, etc.) which are preferably inclined relative to the plane perpendicular to the axis of the instrument. Their inclination can vary between fairly wide limits, but can also be zero.
- the vertical distance between each line (2) and that which is adjacent to it can be between 0.25 and 2 cm, preferably between 0.5 and 1 cm.
- the projections which form the lines (2) project laterally from the side of the instrument (1), over about 0.25 to 0.5 mm, preferably about 0.05 mm.
- the blade (1) has, at one end, the end piece (4) for connection to the device used to actuate the instrument.
- the total length of this instrument is analogous to that of known endodentary files, namely about 12 to 25 mm.
- the thickness of the blade (1) can be between 0.1 and 3 mm, its width between 0.2 and
- any device provided for this purpose can be used, but it is preferable to use devices that generate ultrasound.
- ultrasonic vibrations have intrinsic anti-bacterial properties, and are at the same time capable of detaching tartar residues from the root wall.
- the device is able to reach and file even the most inaccessible areas of the socket, without damaging the residual connective tissue that surrounds it.
- the other side of the blade (1) also has a plurality of parallel lines (5.5 ′, etc.) of projections.
- lines (5.5 ′, etc.) For the inclination of these lines, applies what has just been said for the lines (2.2 ′) etc. with reference to FIG. 1.
- the distance between a line (5) and that which is adjacent to it, is greater than the distance between the lines (2), preferably equal to approximately double.
- the dimensions of the projections (7) which form the lines (5) are smaller than those of the projections (6) which form the lines (2), they are preferably equal to approximately half of the latter.
- the projections (6) have a substantially semi-circular profile and they are gradually connected to the surface of the blade (1). Each of these projections is cut by machining using a suitable tool in the side of the blade (1). The radius of each semicircle is preferably between approximately 50 and 500 ⁇ .
- the projections (6) are intended, during the use of the instrument, to come into contact with the root surface of the tooth. The vibration of the instrument pressed on this surface causes the elimination of the necrotic cementum from the layer of dentin reduced to mud which is formed during the treatment.
- the projections (7) also have a substantially semi-circular profile, like the projections (6) and are cut like these by machining using a suitable tool in the other side of the blade (1).
- the radius of these semicircles is preferably between 25 and 250 ⁇ approximately.
- the vibration of the instrument thus causes not only the elimination of the necrotic cementum, but also the simultaneous elimination of the granulated tissue from the mucous wall of the periodontal alveoli.
- This elimination constitutes one of the objectives of a good treatment of the periodontium, in order to obtain a healthy tissue, free from bacteria and capable of sealing, by adhesion, the treated root surface.
- the section of the blade (1) has a very flat elliptical shape which makes it possible to prepare the flat or slightly convex portions of the root wall.
- This flattened shape also offers the possibility of folding the instrument during use, so as to adapt it to the curves present in the root forks, and make possible the treatment of areas of the root not accessible by the instruments conforming to the technique. known.
- the instrument according to the present invention can be made of any material suitable for this purpose. It is possible, for example, to use materials used in the manufacture of curettes. However, it is preferable to use the titanium alloys recently introduced in the manufacture of endodontic files.
- FIG. 4 shows a variant of the embodiment of FIG. 1.
- FIG. 5 represents another embodiment of the projections which can take the form of tongues raised like teeth (12) of the RISPI (registered trademark) or SHAPER (registered trademark) type, for example three in number on each parallel line, their number may vary depending on requirements.
- RISPI registered trademark
- SHAPER registered trademark
- the blade (1) can take any appropriate section, for example it can be of circular, oblong section, the blade can be cylindrical or conical.
