Definitions

  • the invention relates to an osteotome apparatus used in the surgical sinus floor lifting in order to increase the bone amount in the absence of sufficient bone in the area to be implanted.
  • sinus lifting When implantation is required in the upper jaw, if there is not enough bone, a procedure called sinus lifting or sinus elevation is applied, and the sinus floor is surgically lifted and a bone powder/grafting process is performed. During this process, an apparatus called osteotome is used.
  • the sinus lifting process can be performed with two methods as lateral antrostomy and crestal approach. This study relates to an apparatus that can be used in the crestal approach technique.
  • KR20200118553A discloses a milling tool comprising an implant-guided stopper that has the stop height function and controls the depth. It includes the height-stopping member. A predetermined depth can be adjusted to the guide portion.
  • the International patent document numbered WO2008125449A1 which is in the state of the art, discloses a surgical bone drilling tool. There is a handle to transmit the pressure to the milling head.
  • the bone-cutting process includes a sharply elevated milling ridge that serves as a blade. It includes a body called the milling element that enters inside the bone.
  • the International patent document numbered WO2009136775A2 which is in the state of the art relates to a pressure sensitive drill that can prevent damage to the mucosa by drill when the implant is placed on the maxillary sinus elevation. It includes the elevating blade portion, the cutting blade portion, and the base portion.
  • WO2017035872A1 discloses a memory elastic wire sheath for peeling the mucous membrane of the maxillary sinus, adapted for implant surgeries and/or bone grafting in areas close to the maxillary sinus floor.
  • an osteotome apparatus is placed in the bone cavity opened with a drill, and then the sinus lifting process is performed using a hammer.
  • the osteotome apparatuses in the state of the art cannot perform the sinus lifting process to provide the bone volume required for the attachment of the implant in jaw bone deficiencies. If enough bone is not formed, it will have disadvantages in the durability and lifetime of the implant. In addition, while performing this process, there are risks such as perforation of the sinus membrane in case of excessive insertion of the osteotome apparatus into the cavity within the bone.
  • the object of this invention is to realize the crestal approach maxillary sinus lifting osteotome apparatus to perform the lifting process without damaging the sinus membrane in maxillary sinus lifting processes.
  • Another object of this invention is to realize the crestal approach maxillary sinus lifting osteotome apparatus to perform a wider drilling process on the surface by opening outwards while the lifting blade advances within the jaw bone with hammer impacts and to obtain more bone volume.
  • Another object of this invention is to realize the crestal approach maxillary sinus lifting osteotome apparatus, which includes a ring to prevent the lifting blade from advancing beyond a certain level.
  • Another object of this invention is to realize the crestal approach maxillary sinus lifting osteotome apparatus, which includes level settings to prevent the lifting blade from advancing beyond a certain level.
  • Another object of this invention is to realize the crestal approach maxillary sinus lifting osteotome apparatus to perform the process without graft and allow natural bone formation.
  • Another object of this invention is to realize the crestal approach maxillary sinus lifting osteotome apparatus to eliminate the damage of the graft to the patient by performing the process without graft.
  • Another object of this invention is to realize the crestal approach maxillary sinus lifting osteotome apparatus to perform the process with less cost by performing the process without graft.
  • Figure 1 The schematic view of the crestal approach maxillary sinus lifting osteotome apparatus.
  • Figure 2 The exploded view of the crestal approach maxillary sinus lifting osteotome apparatus.
  • Figure 3 The view showing that the lifting blade is located in level line I of the apparatus of the invention before starting the operation.
  • Figure 4 The view showing that the lifting blade reaches its final state at level line II of the apparatus of the invention after starting the operation.
  • Figure 5 The view when the lifting blade of the apparatus opens and enters into the maxilla alveolar bone during the operation.
  • the invention relates to the crestal approach maxillary sinus lifting osteotome apparatus, comprising
  • the lifting blade (3) which is located between the upper part (1) and the lower part (2) and provides the forward movement within the maxilla alveolar bone (9) in a controlled manner at a certain depth due to its bearing in the cavity in the lower part (2),
  • the ring (6) which is located at the head part of the upper part (1) and the lower part (2) of the body and prevents the apparatus from entering the hole drilled in the maxilla alveolar bone (9).
  • the lifting blade (3) is in the back position when the apparatus is first placed in the maxilla alveolar bone (9) cavity drilled in the jaw.
  • the position of the osteotome apparatus placed on the maxilla alveolar bone (9) is determined by the ring (6) and it is prevented from moving further.
  • the clamping collar (4) around the upper part (1) and the lower part (2) of the body keeps the divided parts of the apparatus together and helps to compress.
  • the lifting blade (3) is centered between the two outer bodies. An impact is applied by the hammer to the handle (5) mounted on the moving lifting blade (3) and the lifting blade (3) moves forward within the maxilla alveolar bone (9).
  • the dentist determines the position to place the apparatus by using the patient's film obtained by imaging. There are level lines on the lifting blade (3), which moves forward within the maxilla alveolar bone (9) with hammer impacts, to adjust the position and not damage the sinus membrane (10).
  • the developed sinus lifting osteotome apparatus is a mechanical osteotome apparatus used in sinus lifting surgical operations.
  • the developed osteotome apparatus has a design to enable a wider drilling process on the surface.
  • the lifting blade (3) which is placed between the upper part (1) and the lower part (2), moves forward within the maxilla alveolar bone (9) with the hammer impacts applied to the handle (5), the lifting blade (3) opens outwards and the wider drilling process is performed on a surface.
  • the indicated level lines can show the depth of the hole drilled in the maxilla alveolar bone (9).
  • the ring (6) prevents excessive insertion into the hole drilled in the maxilla alveolar bone (9), and thus prevents damage to the sinus membrane (10).
  • level line I (7) is aligned with the end of the lower part (2), as seen in Figure 3.
  • the level line II (8) on the lifting blade (3) becomes aligned with the end of the lower part (2), as seen in Figure 4.
  • the end of the lifting blade (3) made of heat-treated stainless steel fits the form of the outer body parts and stretches outward and provides a larger diameter drilling in the maxilla alveolar bone (9).
  • the lifting blade (3) is prevented from moving beyond a certain level.
