Description

Implant point drill guider for implants

      The present invention relates to a point drill aid for implants, and more particularly, to a point drill aid for implants to more accurately and safely implant the implant into the patient's alveolar bone.

  Implant (implant) is a kind of prosthesis that is used to replace the missing teeth can be performed individually without damaging the connected teeth, has a relatively long life and is one of the most recent medical techniques.

  The selection of the point to be punctured according to the tooth spacing, alveolar bone width and alveolar bone condition during implantation is very important, and it is very important for the operator so that it is not an exaggeration to judge the success and failure of the implant in a broad sense.

  In addition, the setting of the path direction of the point is important along with the setting of the point point because it is an important factor that determines the form of fixture placement.

  Recognizing the importance of point setting in overseas, various types of implants provide point drill guide kits (kit) for precise procedures, but domestically these products and technologies are very limited.

  Therefore, the present invention relates to a point drill aid for an implant that can be accurately selected in the drilling position selection of the point drill prior to implant placement, and can help stabilize the drilling during drilling.

      The most commonly used screw implants include soft tissue surgery to open the gum in the area where the implant is to be inserted, bone removal surgery to remove the cortical bone and reticular bone to form points in the alveolar bone, and to insert the implant after bone removal surgery. After the stabilization period to allow bone adhesion, connect the pedestal of the implant out of the gum so that the tooth can be inserted.When the gum is completely clear and the implant is confirmed to be fixed to the bone, a series of teeth are produced and bonded to the implant. It is performed through the process.

  The number and location of implants to be placed are determined in consideration of the patient's oral condition, X-ray results, etc., but conventionally, the location of implants is determined using an initial point drill, depending on the experience and know-how of the operator. .

  Conventional techniques for selecting an initial point drill position in an implant procedure are as follows. First, it is used to find the exact location of the implant by making a model of the same shape as the patient's teeth before implantation is made of resin (acrylic) and the like is inserted and fixed to the adjacent teeth. It is a method to set the initial drilling point by drilling in the center of the fixed model tooth. Second, as described in Republic of Korea Patent Registration 10-0535444 to make the initial drilling point by making the stent aids determined according to the oral cavity in the patient. In addition, the operation time is shortened to determine the puncture angle, and the operation is easy, thereby reducing the fatigue of the operator. Lastly, as described in Republic of Korea Patent Registration 10-0829244 it describes a drilling aid for sliding implant implants for forming a plurality of points.

  Conventional techniques have often caused excessive perforations or inaccurate positions in the point drill operation, and sometimes caused by complications and re-perforation operations because they were not drilled to a sufficient depth. In addition, it is necessary to manufacture and change the assisting tool in consideration of the oral condition of the patient has a disadvantage in that the time required for the operation changes.

  Implant point drill aids are required to accurately position the drill and maintain the drilling angle during drilling. When the gap is small, the gap between the drill and the auxiliary tool is not appropriate, so the shaking is small, so that accurate drilling is possible, but it is difficult to change the drilling angle. If the gap is large, the drilling angle can be easily changed. An error may occur in determining the puncturing angle.

  In addition, when drilling the alveolar bone, the scale of the drill is checked on the surface of the alveolar bone, so that the perforation area of the bone on the alveolar bone is located deep inside the oral cavity, so that the field of vision is narrow and not accessible, and bleeding generated during surgery If covered, it is not easy to check the scale of the operator.

Include.

  In the point drilling operation during the implant procedure, find a drilling aid that matches the gap between the tooth and the missing tooth, fix the drilling aid between the tooth and the tooth, and then drill in the center of the alveolar bone width After tightening the assisting tool and the joining tool, drill the point in consideration of the drilling direction.

  The joining aid is firmly fastened with the drilling aid so that the drilling operation does not cause the shaking of the drill, and it is possible to accurately know the progress and the drilling depth of the drill by placing an opening marked with the graduation aid.

  With the configuration as described above, in the point drilling operation for the implant, it is possible to select a simple and accurate drilling position and direction, and stable drilling operation.

Point drill aid for implants of the present invention as described above has the following advantages.

  First, it is possible to easily measure the distance between teeth by using various sizes of drilling aids in order to implant the implant where the teeth are missing, and the width of the alveolar bone is also easily measured. It is possible to precisely and reliably implant the implant by being located at. Therefore, the operation time is shortened, the operation is easy, and the fatigue of the operator as well as the patient can be reduced.

  Second, the induction of the drill by the drilling aids can prevent the shaking of the drill during drilling to pierce the alveolar bone stably and accurately.

  Third, when the joining aid is in contact with the alveolar bone after joining the drilling aid, the drill depth plus the length of the assist tool is added to the top of the assist tool to provide accurate drilling depth even for obstacles such as bleeding during surgery. This can improve the stability of implant surgery.
