Definitions

  • This invention relates to a new bone drill system which can be used to open implant sockets in the jawbone through the gingiva by means of a guide or surgical lead.
  • a dental surgeon who intends to place an implant also views panoramic and tomographic images, examines models if available, and makes analyses with 3D imaging software, if utilised.
  • the dental surgeon makes the relevant decisions in view of the choice of implant, the placement, position and angle of implant, and anatomical relations of the implant. After these decisions are made the turn comes to open a socket in the patient's jawbone in accord with the intended implant and these theoretical plans.
  • There are two methods for opening implant sockets in bone The first method involves a surgical incision in the gingiva and drawing the gingiva tissue aside to expose the bone.
  • the second method does not involve surgical action on the gingiva and the implant is placed directly through the gingiva. For example, an implant with a diameter of 4 mm will only require opening a circular window with a 4 mm diameter on the gingiva.
  • the dental surgeon may choose any one of these two methods according to requirements of the case.
  • the dental surgeon decides the placement, angle and position of the socket to be opened in the bone in accord with the planning of intended implant.
  • the dental surgeon tries to measure and determine the depth of implant socket due to close proximity of anatomical structures like nerve channels and sinus cavity.
  • One method involves utilisation of straight drills with markings in various scales. While the drill opens a socket in the jawbone the dental surgeon follows the relation between the bone level and these markings to determine socket depth and decide when to stop drilling. In cases where the view is obstructed due to bleeding, etc. the depth of the socket can be checked by means of scaled control rods.
  • the drill has stopper sections which fix the intended depth. For example, in case the utilised drill is 11 mm in length, the stopper section ensures that only an 1 1 mm deep socket can be drilled, and it would not be possible to go any deeper than 11 mm.
  • stopper drills can be used in both incision & direct bone contact operation method and directly through gingiva operation method. The success of the implant placed by these methods greatly depends on the knowledge, experience, manual skill and general conduct of the dental surgeon.
  • Dental surgeon may only rely on his knowledge and experience in opening an implant socket in the bone, or utilise guides and surgical leads in order to increase accuracy.
  • the number of these guides or surgical leads can be 3 or 4 pieces or more according to the intended implant diameter.
  • guides or surgical leads allow accurate determination of the position and direction of the implant socket with straight drills. Since the guides or surgical leads obstruct the view of bone level during operation the socket depth cannot be accurately determined during operation and can only be determined by the dental surgeon by means of surgical measurements after removal of guides or surgical leads. In view of the number drills and guides/surgical leads involved in such an operation, this kind of procedure causes a great loss of time and effort.
  • Straight or stopper type bone drills are used to open implant sockets in bone in scope of the field of implant operations. These drills are generally planned by implant manufacturers for their own implants, but they can also be used for other implants as long as the parts are compatible. 1) "Straight bone drills" without stopper, used to open implant sockets in the bone by means of open surgery or directly through the gingiva without surgical intervention, without use of any guide or "surgical lead", are excluded.
  • inventive bone drill fall in scope of the field of "stopper bone drills" used to open implant sockets in the bone by means of open surgery or directly through the gingiva without surgical intervention, involving use of some guide or "surgical lead”.
  • the inventive stopper bone drill is similar to other stopper bone drills utilised "without use of any guide or surgical lead" and can be used by dental surgeons to open implant sockets in the bone by means of open surgery or directly through the gingiva without surgical intervention without use of any guide or surgical lead if they so desire.
  • this only constitutes an advantage provided by the inventive bone drill.
  • the main characteristic of importance of the invention is the fact that when used together with a guide or surgical lead" the properties of the inventive drill ensures that the implant socket in the bone can be opened a) Exactly at the desired position, b) Exactly at the desired angle and c) Exactly at the desired depth, in accord with implant planning.
  • Best known methods in the state or art have some problems in operation of drills.
  • One of these involves jacketing the bone drill in a stopper.
  • the bone drill can be controlled in regard of position, angle and depth, but the stopper continues to turn in the guide and the drill continues to turn in the stopper. This in turn causes losses in drill torque and heating in the drill (which are unwanted conditions in the field of implant operations).
  • the bone side tip of the stopper is conical in shape, which can cause instability in the drill when the tip works through the guide or surgical lead and commences first action on the bone.
  • Guides or surgical leads are suitable for the purpose, but these parts are very expensive.
  • Bone drills currently in production and on the market allow opening implant sockets and placement of implants, but they generally completely leave successful placement of these implants in the position, angle, depth and anatomical relation as intended by the planning dependent on the success of the dental surgeon.
  • Figure 1 illustrates the inventive bone drill for opening implant sockets in the jawbone.
  • the end marked with the number 1 for attachment to the hand piece and the cutting tip marked with the number 4 are similar to other drills.
  • the main object of this invention is the guide compatible cylindrical stopper section marked with the numbers 2 and 3.
  • the diameter of the cylindrical stopper marked with the number 2 is 4.0 mm for Set Part 1 and 2 (marked with A) and it is 5.0 mm for Set Part 3 (marked with B).
  • the size of cylinder stopper is 9.0 mm in total, comprised of 1.0 mm in conical bone contact section marked with the number 3, and 8.0 mm in cylinder section marked with the number 2.
  • Drill Set Part 1 Drill diameter starts at 1.0 mm and increases by 0.1 mm steps in each drill bit up to 1.9 mm. Length of drill cutting tips starts at 5.0 mm and increases by 0.5 mm steps in each drill bit up to 14.5 mm. This part includes a total of 200 drillbits. Diameter of guide compatible cylindrical stopper section is 4.0 mm.
  • Drill SetPart 2 Drill diameter starts at 2.0 mm and increases by 0.1 mm steps in each drill bit up to 3.7 mm. Length of drill cutting tips starts at5.0 mmand increases by 0.5 mm steps in each drill bit up to 14.5 mm. This part includes a total of 360 drillbits. Diameter of guide compatible cylindrical stopper section is 4.0 mm. Drill SetPart 3: Drill diameter starts at 3.8 mm and increases by 0.1 mm steps in each drill bit up to 4.7 mm. Length of drill cutting tips starts at5.0 mmand increases by 0.5 mm steps in each drill bit up to 14.5 mm. This part includes a total of 200 drillbits. Diameter of guide compatible cylindrical stopper section is 5.0 mm.
  • the dental surgeon may also incise and draw aside the gingiva to expose the bone and perform the same operation with a guide or surgical lead.
  • dental surgeons who do not use tomography and 3D modelling software the success of operation remains fully dependent on the surgeon's medical competence, which is again outside the scope of this invention.
  • dental surgeons who utilise tomography and 3D modelling software can use a guide or surgical lead produced specifically for the case together with the inventive bone drill to open an implant socket compatible with the planned implant in the bone and place the implant in the socket in the exact position planned in 3D modelling of the operation.
  • the guide compatible cylindrical stopper marked with the number 2 on drawing page in Figure 3 moving inside the guide tube marked with the number 6 in Figure 3 ensures that the tip and side surfaces of the drill bit acting on the bone, marked with the number 4 in Figure 3, do not contact the guide or the surgical lead. This ensures that the cutting tip of the drill does not suffer any abrasion or loss due to contact with the guide tube marked with the number 6 in Figure 3.
  • the guide compatible cylindrical stopper marked with the number 2 on drawing page in Figure 3 operating and moving inside the guide tube marked with the number 6 in Figure 3 ensures that the tip and side surfaces of the drill bit acting on the bone, marked with the number 4 in Figure 3, do not contact the tube in the guide or the surgical lead.
  • the inventive bone drill provides great savings in guide or surgical lead costs. Only one guide or surgical punch is sufficient, also even allowing use of gingiva punch. The opportunity to utilise a single guide or surgical guide when opening an implant socket in the bone is an important innovation in the field of implant operations. Drill systems in the state of art require minimum three or more guides or surgical leads.
  • inventive drill eliminate the need for making any measurement to determine the direction and the depth during the operation of opening an implant socket in the bone. This also is an innovation in the field of implant operations.
  • the characteristics of the inventive drill ensures that there is no need to remove the guide or the surgical lead from the gingiva during the operation. After the guide or the surgical lead is ensconced in the place of the missing tooth it stays in place until the implant socket is opened by means of necessary number of drills and only removed after its task is completed. Then the implant can be placed into the socket. Since this procedure takes a very short period of time it promotes the morale of both the dental surgeon and the patient as well as providing great savings in time and effort.
  • the inventive bone drill eliminates the need for surgical intervention on the gingiva and provides great advantages in comparison to methods which involve surgical incision of gingiva and exposal of the bone. This characteristic provides a great morale boost for patients who wish to have an implant placed in their jawbone.
  • surgical interventions also bring along the potential for other undesired results, which constitute a greatly dissuasive handicap for patients.
  • Implant operations involving surgical interventions can result in pain, swelling, bleeding and haematoma resulting in bruises on the cheek, and patients can face difficulties in eating after surgical intervention.
  • the sutures in the surgical intervention area can also bother the patient for many days.
  • the undesired or negative consequences of surgical interventions in regard of incision recovery and infection can also have greatly negative influences on the success of implant operation.
  • the inventive bone drill allows only opening a window limited to the diameter of the implant in the gingiva without any surgical intervention, thus eliminating all known surgical problems. There is no bleeding, pain or swelling, no sutures are needed on the gingiva, and since recovery starts as soon as the implant is placed the patient is able to eat as soon as they wish. In aggregate, the inventive drill ensures that the patient's life quality stays as high as possible even on the day of implant operation. 8) When used in conjunction with a guide or surgical lead prepared by means of tomography aids, the operation stages of the inventive bone drill are clear and easy to understand, allowing operators to learn them easily, thus making the inventive drill comfortable and safe to use for any dental surgeon who wish to perform implant operations.
  • the inventive bone drill can be used with all implant hand pieces.
  • the inventive bone drill and its sets can open sockets for all available implants.
  • the inventive drill can be used in conjunction with these to easily open a socket compatible with the planned implant at the exact desired position, direction and depth in the bone.
  • This model of operation requires a window only at the diameter of the implant itself to be opened on the gingiva, thus ensuring that no serious bleeding of clinical significance is experienced during the operation.
  • the recovery cap is immediately placed and thus no bleeding is experienced from this step on.
  • This model of operation allows operation without any need for surgical intervention and thus provides a great advantage.
  • This system can be easily used at any consulting office, polyclinic or hospital without requirement of any special equipment or surgery room conditions.
  • the main characteristic of the inventive bone drill constituting the subject of this patent application is the guide compatible cylindrical stopper section of the bone drill, marked with the number 2 and 3 on drawing page 3/1 in Figure 1 and on drawing page 3/3 in Figure 3.
