Title: Vibrational filling device for implanting tooth bone powder

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the invention 
     The present invention relates to a vibrational filling device for implanting tooth bone powder, and especially to a filling device to fill bone powder in a vibrating mode into an area below a nasal sinus film able to be separated and lifted from a cortical bone. 
     2. Description of the Prior Art 
     In planting teeth in a oral cavity, for the purpose of increase the thickness (height) of the cortical bone  10  at the area to be implanted with the teeth in a sinus floor, the sinus floor shall be performed with a surgical operation of osteotomy, such as is shown in  FIG. 1 , an upper opening  11  shall be formed by drilling on a cortical bone  10 . Then as shown in  FIG. 2 , a tool is used to separate and lift the sinus film  12  from the opening  11 , and a pushing needle  22  of a bone powder filling tool  20  is used to fill bone powder  13  in a space below the separated and lifted sinus film  12  to increase the thickness (height) of the cortical bone  10  in favor of the process of the subsequent tooth implanting. 
     A conventional bone powder filling tool  20 , as shown in  FIG. 3 , is a simple tool made of metal material, it has a handle  21  having on its one end a pushing needle  22 ; the pushing needle  22  is extended into the opening  11  after being attached with bone powder  13 , the bone powder  13  is filled in the space below the separated and lifted sinus films  12 . 
     Such a conventional manual tool is operated with a hand for filling in, it renders the action of filling bone powder  13  very hard and slow, hence time of operation is increased, not only a patient fills more uncomfortable, but also a doctor in charge of the operation feels the operation is a time and physical strength extremely consumptive work; particularly for a raw recruit, the work is more difficult, and improvement is wanted. 
     SUMMARY OF THE INVENTION 
     The present invention provides a vibrational filling device for implanting tooth bone powder against the defect of the conventional bone powder filling hand tool, the filling device fills the bone powder into an little opening provided on a cortical bone with average pressure in a vibrating mode, for the purpose of reducing the time for surgical operation, reducing discomfort of patients and increasing the quality of operation processes of tooth planting, the patients and doctors can thereby both be favored. 
     The vibrational filling device for implanting tooth bone powder of the present invention mainly has a hand piece able to create vibration and adapted for holding by a hand, an end of the hand piece is connected to a changeable bur, the bur takes advantage of the vibration created by the hand piece to propitiously fill bone powder into an area below a nasal sinus film able to be separated and lifted from a cortical bone to increase the thickness of the cortical bone. 
     The hand piece of vibrational filling device for implanting tooth bone powder of the present invention can create vibration in an electric or air actuating mode. 
     The present invention will be apparent in its structure and its way of operation after reading the detailed description of the preferred embodiment thereof in reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring to  FIG. 4 , a vibrational filling device  30  for implanting tooth bone powder of the present invention mainly has a hand piece  31  adapted for holding by a hand, and has a changeable bur  32 . 
     The hand piece  31  is provided therein with a vibration creating device  311  which can create vibration in an electric or air actuating mode. And a front end of the hand piece  31  is connected to the changeable bur  32  of which the surface is plated with titanium, the bur  32  has a size to be able to extend in an opening  11  as shown in  FIG. 5 , and is provided on its end with a cylindrical portion  321 . The other end of the bur  32  being merged in the hand piece  31  is connected with the vibration creating device  311  that can create vibration to fill the bone powder  13  from the opening  11  into an area below a nasal sinus film  12  able to be separated and lifted from a cortical bone  10  with an average pressure to increase the thickness of the cortical bone  10 . 
     And more, the hand piece  31  of the present invention can be connected to a main control unit  33  to control vibration generation of the vibration creating device  311  in an electric or air actuating mode. 
     The vibrational filling device  30  for implanting tooth bone powder of the present invention mainly is used to propitiously fill the bone powder  13  from the opening  11  on the cortical bone  10  into an area below a separated and lifted nasal sinus film  12  with an average pressure to overcome the difficulty of operation resided in a conventional hand tool. By virtue that the vibrational bur  32  fills the bone powder  13  into the cortical bone  10  fast and automatically, an effect of reducing the time for surgical operation, reducing discomfort of patients and increasing the quality of operation processes of tooth planting can be obtained, the patients and doctors can both be favored. 
     In conclusion, according to the description disclosed above, and having particularly described and ascertained the novelty and improvement of my invention and in what manner the same is to be performed, what we claim will be declared in the claims followed.
