Background

After a period of time following implantation, it is common for the implant to change its tightness with the abutment teeth, and if this change is loosening, intervention and calibration is required. Conventionally, the tightness of the abutment teeth is generally determined by a doctor by sensing a change in resistance (frictional force) between the pair of abutment teeth after inserting the metal insert between the pair of abutment teeth and during the process of removing the insert twice before and after the insert is removed. The judgment is subjective judgment, and the process of pulling out the insert piece from two sides can be separated by a period of time, so that even the same doctor can hardly remember the resistance feeling of pulling out the insert piece last time, which brings difficulty to the judgment.

Detailed Description

Hereinafter, the cavity tooth abutment contact tightness measuring device of the present application will be described in detail with reference to the accompanying drawings.

The utility model provides an oral cavity tooth is adjacent to touching elasticity measuring device, it includes: handle member 10, slide member 40, wheel member, tension gauge 20.

The handle member 10 includes a first section and a second section connected together, the second section forming a predetermined angle with the first section, e.g., 120, 135, 150 degrees, etc.; here, the first section and the second section may be rotatably connected together, for example, fixed together by a bolt, in which case, a user may adjust an included angle between the first section and the second section as desired, and then fix the included angle by rotating the bolt, so that the second section held by the operator is obliquely extended out of the oral cavity of the patient, without interfering with an extending direction of the pull wire 16 described later, and the operation is more convenient. The first and second segments together constitute a handle body 11.

A first end of the first section is formed with an end wall 12, the end wall 12 extending in a direction of a rear side of the handle member 10; the end wall 12 is formed with a slide guide groove 12a in the up-down direction; the middle of the first section is formed with a rotating shaft 13. The rotation shaft 13 extends toward the rear side of the handle member 10.

The sliding member 40 is formed in a plate shape, a first side of which forms a slide rail 43 and a second side of which forms a rack, and a rear side of the sliding member 40 is used for installing the insert 30 to be inserted between adjacent teeth for measuring abutting contact tightness; the slide rail 43 is slidably mounted in the slide guide groove 12a of the end wall 12; the cross-sectional shape of the slide rail 43 corresponds to the cross-sectional shape of the slide guide groove 12 a.

The wheel member includes a gear 15a and a spool 15b connected together, where the gear 15a and the spool 15b may be integrally connected together or may be connected together through a speed reducing mechanism; the gear 15a and the spool 15b are rotatably mounted on the rotating shaft 13; a pull wire 16 is wound on the bobbin 15a, and the pull wire 16 can be a thin steel wire or a nylon wire; a first end of the pulling wire 16 is fixed to the spool 15 a; the gear 15a is meshed with the rack. The diameter of the gear 15a may be larger than that of the spool 15b, so that the pulling force applied by the pulling wire 16 needs to be larger than the force of the gear 15a driving the rack (the force is equal to the friction or resistance to be measured during uniform motion), which plays a role in amplifying the resistance, and the small resistance change can be displayed in an amplified manner by the tension meter 20.

A tension meter 20 is attached to a second end of the pull wire 16.

The handle member 10 has a guide ring 14 formed thereon; the second end of the pull wire 16 extends through the guide ring 14 in the direction of the second end of the handle member. The guide ring 14 is adjacent to the location where the first and second sections of the handle member are connected. The guide ring 14 and the end wall 12 are located on both sides of the rotation shaft 13, respectively.

The slide guide grooves 12a are dovetail grooves, and in this form, the slide rails 43 do not come out of the slide guide grooves 12 a. The both ends of the sliding guide groove 12a are respectively formed with a stopper, so that the slide rail 43 can be prevented from being accidentally dropped from the both ends of the sliding guide groove 12 a. The slide guide groove 12a is not limited to the dovetail groove, since the slide member is fitted between the slide guide groove 12a and the rotary shaft 13, and is not liable to fall off by itself.

A tab mounting base 41 is formed on the rear side of the slide member 40, and the tab 30 is detachably mounted on the tab mounting base 41 and is perpendicular to the plate-shaped slide member 40. This has the advantage that the sliding member 40 is not in the direction of movement of the blade 30, leaving more room for movement of the blade 30, especially in tight spaces.

An insert rod 42 is formed on the mounting table 41, and an insert hole 31 is formed on the insert sheet 30; the insertion hole of the blade 30 is fitted over the insertion rod 42 of the mounting table 41, thereby mounting the blade 30 on the mounting table 41. Two insertion rods 42 are formed on the mounting table 41, and two insertion holes 31 are correspondingly formed on the insertion sheet 30.

The mounting table 41 is provided with a magnet block, the end of the insert 30 comprises a ferromagnetic material, and the insert 30 is attracted and fixed on the mounting table 41. For example, a groove is formed on the mounting table 41, and the insert 30 is caught in the groove after being sucked on the mounting table, so as to prevent relative displacement with the mounting table during up-and-down movement.

Or both the inserted bar and the magnet block can be arranged.

When the dental appliance is used, the inserting sheet can be inserted between the

adjacent teeth

51 and 52, then the oral cavity teeth adjacent contact tightness measuring device extends into the oral cavity of a patient, the sliding component is connected with the inserting sheet, as shown in fig. 12, then a doctor holds the second end of the handle component by one hand outside the oral cavity of the patient to stabilize the whole device, the other hand pulls the tension meter connected to the second section of the pull wire, the pull wire drives the spool to rotate, the spool drives the gear to rotate, the gear drives the rack to move upwards, the rack drives the sliding component to move upwards, so that the inserting sheet arranged on the sliding component also moves together and is pulled out from the adjacent teeth; the insert is pulled out at a constant speed as far as possible, and the friction force can be judged or determined through the reading of the tension meter.
