Description

Technical Field

[0001] This utility model relates to the field of dental technology, and in particular to a dental implant stability testing instrument. Background Technology

[0002] A dental implant stability tester is a non-invasive testing device that utilizes the principle of Resonance Frequency Analysis (RFA). It is primarily used to assess the degree of osseointegration (osseointegration) between the implant and the alveolar bone. Its core function is to quantify stability by measuring the implant's vibration frequency, thereby guiding the selection of the appropriate timing for clinical restoration.

[0003] Existing dental implant stability testing instruments are relatively long, with shells typically made of polyvinyl chloride. The probe is also quite thick and short, making it inconvenient to insert into the patient's mouth. The charging port is located at the bottom of the instrument, which is usually placed horizontally on the table during charging, taking up a lot of space. It is also prone to water damage due to misoperation by medical staff. Furthermore, charging requires medical staff to use both hands to plug and unplug the device, which is inconvenient.

[0042] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0043] Example:

[0044] Reference Figure 1 and Figure 2 This embodiment provides a dental implant stability tester, including a handle body 100 and a charging base 200. The handle body 100 is used in conjunction with a sensor installed on a dental implant to detect the degree of osseointegration between the dental implant and the alveolar bone. The charging base 200 is used to place the handle body 100 and charge the handle body 100.

[0045] See Figure 2 and Figure 3 The handle body 100 includes a housing, a main control circuit board assembly 2 installed inside the housing, a power supply 3, and an induction coil assembly 5. The power supply 3 uses a commercially available rechargeable battery. The induction coil assembly 5 is installed at the upper end of the handle body 100 and is electrically connected to the main control circuit board assembly 2. The power supply 3 supplies power to the main control circuit board assembly 2 and the induction coil assembly 5. The main control circuit board assembly 2 includes a PCB board and a charging interface 21. The charging interface 21 is soldered to the lower end of the PCB board and is exposed from an opening in the bottom wall of the housing.

[0046] See Figure 2 , Figure 4 and Figure 5 The charging dock 200 includes a charging base 71 and a lower base cover 72, which are connected together by bolts and form an inner cavity. The top of the charging base 71 is recessed downward to form a charging groove 711, which is adapted to the lower end of the handle body 100. A pin plate 8 is installed in the inner cavity of the charging dock 200 at a position opposite to the charging interface 21. The conductive pins on the pin plate 8 extend into the charging groove 711 for connecting with the charging interface 21 to charge the handle body 100. The pin plate 8 is provided with multiple conductive pins to correspond to the electrode layout of the charging interface 21 to ensure a stable electrical connection.

[0047] When charging, simply insert the handle body 100 into the charging slot 711 to start charging. Remove the handle body 100 from the charging slot 711 for use. Compared with existing technologies, charging the handle body 100 by placing it upright on the charging base 200 saves space, is less likely to be accidentally damaged by medical staff, and can be completed with one hand for charging and power-off operations, making it more convenient to operate. This solves the technical problem of inconvenient charging operation of existing dental implant stability testing instruments.

[0048] See Figure 2 and Figure 5 The charging interface 21 is fitted with a first insulating sleeve 22, and a second insulating sleeve 80 is installed on the top of the inner wall of the charging base 200. The pin plate 8 is connected to the second insulating sleeve 80. The conductive pins pass through the second insulating sleeve 80 and the first insulating sleeve 22 in sequence and are connected to the charging interface 21. The bottom surface of the charging slot 711 is sloped, and the lower end of the handle body 100 is provided with an inclined surface. The slope and the inclined surface fit together seamlessly and tightly. Therefore, the handle body 100 will not deflect on the charging base 200, and there will be no problem of liquid seeping into the charging port and the conductive pins, making charging more stable and reliable. Both the second insulating sleeve 80 and the first insulating sleeve 22 are made of high dielectric strength material.

[0049] See Figure 2 and Figure 4 The charging dock 200 also includes a charging connection board 9, one end of which is connected to an external power source 3, and the other end is electrically connected to a pin plate 8.

[0050] In some feasible solutions, the outer casing includes a main shell 11, a front cover 12, a handle connector 15, a connecting elbow 16, and a probe 17. The main shell 11 is a one-piece molded metal part with a chamber for installing the main control circuit board assembly 2 and the power supply 3. A waterproof ring 13 is provided at the contact position between the front cover 12 and the main shell 11. The front cover 12 is sealed and installed on the front of the main shell 11 by fixing bolts 42. A waterproof ring 14 is provided between the handle connector 15 and the top of the main shell 11. The handle connector 15 and the main shell 11 are sealed together by fixing bolts 42, resulting in better waterproof performance of the handle body 100. The two ends of the connecting elbow 16 are threadedly connected to the handle connector 15 and the probe 17, respectively. The design of the handle body 100 head, incorporating the handle connector 15, connecting elbow 16, and probe 17, allows for greater design space, enabling it to be thinner and longer, facilitating the insertion of the handle body 100 head into various positions within the patient's mouth for operation. The bend angle of the handle body 100 can be set according to actual needs, ranging from 105 degrees to 120 degrees, as long as it can reach the back teeth area.

[0051] In actual production applications, a display unit is connected to the front of the PCB board, and a display lens 121 is installed on the front cover 12 at a position opposite to the display unit, allowing direct viewing of the test data. A light-transmitting sheet 111 is installed on the back of the main housing 11, and the light-transmitting sheet 111 is positioned opposite to the display lens 121.

[0052] See Figure 2 and Figure 3 A switch button 23 is installed on the rear side wall of the main shell 11 to control the opening and closing of the handle body 100.

[0053] In some feasible solutions, the housing is also provided with a fastening assembly, which includes a fixing screw 41, a fixing bolt 42, and an insulating washer 43. One end of the fixing bolt 42 passes through the PCB board and is threaded to the rear side wall of the main housing 11. The fixing screw 41 passes through the main housing 11 and is connected to the fixing bolt 42 to fix the PCB board in the main housing 11. An insulating washer 43 is provided between the fixing bolt 42 and the PCB board. For a more aesthetically pleasing appearance, a label is affixed to the front of the main housing 11 at the position corresponding to the fixing screw 41 to cover the fixing screw 41.

[0054] The sensor is fixed to the implant in the patient's mouth by threaded engagement and vibrates when excited by an electromagnetic pulse. The induction coil assembly 5 is used to release electromagnetic pulse signals to the sensor and receive feedback signals. The induction coil assembly 5 includes a coil body and a magnetic rod, and uses commercially available components.

[0055] During the test, the dentist inserts the handle body 100 into the patient's mouth, close to the sensor at a distance of no less than 2mm. The induction coil assembly 5 emits electromagnetic pulses to stimulate the sensor to vibrate. The coil body receives the vibration signal and transmits it to the main control circuit board assembly 2. The main control circuit board assembly 2 analyzes the resonant frequency and calculates and converts it into the Implant Stability Quotient (ISQ) using a preset algorithm, which is then displayed on the display unit. The entire process is non-invasive and highly efficient. The handle body 100 can test the stability of various dental implants, has strong compatibility, and is suitable for initial implant stability assessment and healing period follow-up assessment. The electromagnetic pulse frequency emitted by the induction coil assembly 5 is between 100Hz and 6000Hz.
