Definitions
- the present invention relates to an alveolar distractor with which to perform a distraction or contraction between alveolar bones. It is applicable in bone medicine and especially in the field of oral implantology.
- the recipient For oral rehabilitation through implants, the recipient must offer the implant a bed with a bone volume and height that allows adequate stability of said implant. To provide that bed, once the bone loss has occurred, the patient must undergo an alveolar reconstruction, in which the volume of bone in which the implant is subsequently fixed within the socket is increased.
- an alveolar distraction process is performed, said process has a reduced application due to the complexity of the necessary surgical technique.
- Said alveolar distraction is a technique that increases the height of the alveolar ridge by promoting the formation of new bone and a significant increase in the surrounding soft tissues (stable bed for implantation). This technique offers a predictable result, with low morbidity and infection rates, and a significantly shorter waiting period for implant placement, compared to traditionally used methods.
- traction is applied to a portion of bone, which undergoes a vertical displacement until it is at an optimal or planned height. The displacement process of this fragment results in the regeneration of tissues, both hard (bone) and soft (gum), during the said process.
- osteotomy For the placement of a device that performs alveolar distraction, the execution of a osteotomy (cuts in the bone), so that a bone fragment (plaque) is released, leaving a free area (osteotomy line) between the bone fragment and the rest of the maxilla.
- the alveolar distractors of the state of the art are formed by two pieces that are fixed to the maxillary bone one, and another to the bone fragment released in the osteotomy, leaving a piece on each side of the osteotomy line. This placement is of great difficulty and not only depends on the skill and experience of the surgeon, since in many situations the areas of placement of the distractor are areas of great atrophy, therefore of difficult access and zero visibility, being very difficult prognosis the success of said surgery.
- WO 2010/061391 Al shows a bone distractor to increase the height and width of an alveolar ridge comprising a lifting platform to distract a mobile segment of the alveolar ridge from a segment of the stationary crest of said alveolar ridge, an expansion platform to distract a buccal section and / or lingual of a section of the movable ridge, and an element to make the lifting platform move relative to the stationary crest segment.
- US 6 280 191 Bl shows a distractor suitable for permanent placement in the bone, and refers to a distractor suitable for indexed osteotomy after permanent implantation in the bone.
- the distractor is a means for joining two or more bone sections and a means for facilitating the movement of a bone section in relation to another bone section.
- Document ES 2 162 555 Bl shows an alveolar bone distractor consisting of a folding structure that delimits a flat articulated polygonal contour composed of two parallel and facing supports, which are related by means of an intermediate screw and two pairs of arms that are symmetrical with respect to the plane means that passes through the screw and are articulated to each other and to the supports.
- One of the arms is layered and at its free end it has an elongated bone fixation head.
- the present invention relates to an alveolar distractor with which to perform a distraction or contraction between maxillary bones.
- the alveolar distractor object of the invention performs a distraction of a bone fragment with respect to a maxillary bone, the bone fragment and the maxillary bone being separated by a free zone (osteotomy line).
- the distractor comprises a threaded shaft, an upper body and a lower body, also the threaded shaft comprises an upper part (in which the thread has a direction of rotation), and a lower part (in which the thread has a sense of turn opposite the direction of rotation of the upper part).
- the upper body is located in the upper part of the axis and the lower body is located in the lower part of the axis.
- Both the upper body and the lower body of the alveolar distractor object of the invention comprise an end zone without external thread (free ring).
- the two bodies are in contact with each other (joined), they have the respective areas without external thread in contact, generating in the junction zone of the two bodies a ring without thread (free ring) which, in the patient is placed in correspondence with the free zone that separates the bone fragment from the maxillary bone, the lower body of the distractor being on one side of the osteotomy line and the upper body on the other side of said osteotomy line, thus allowing the displacement along the axis of the two bodies, approaching or moving away from each other.
- the lower body is shorter than the upper body, providing stability to the upper body within the maxillary bone.
- the upper part of the shaft It comprises a thread pitch other than the thread pitch of the lower part of the shaft.
- the thread pitch of the upper part of the shaft is greater than the thread pitch of the lower part of the shaft.
- the threaded shaft comprises a concavity at one end through which a rotation of the threaded shaft is executed by actuating a key that is inserted into said concavity.
- At least one of the bodies comprises a through hole, which gives access to the concavity of the shaft through said through hole with the bodies placed on the threaded shaft.
- one of the bodies comprises a male element and the other body comprises a female element, which are connected by the interior of said bodies, when the two bodies are joined.
- both the male element and the female element have a shape such that the threaded shaft passes through them.
- Figure 1 shows another side view of the device object of the invention.
- Figure 2 shows a sectional view of the device object of the invention configured as that of Figure 1.
- Figure 3 shows a side view of the alveolar distractor in its original state before beginning the alveolar distraction process.
- Figure 4 shows a side view of the alveolar distractor placed after the end of the alveolar distraction process.
- the object of the invention is a device with which to perform the distraction or contraction of two bones or bone parts, being especially indicated for application in maxillary bones. ( one ) .
- the different elements of the invention have been named by dividing the invention into the upper and lower part following a geometric criterion and taking as an example a distractor located in a maxillary bone (1) of the patient.
- the device object of the invention is placed in the maxillary bone (1) of the patient after an osteotomy has been performed. This osteotomy is completed until a bone fragment is released (2).
- the device object of the invention (observable in figures 1 to 4) comprises an upper body (3), a lower body (4) and a threaded shaft (5) in which both the upper body (3) and the threaded bodies are placed the lower body (4).
- Both the upper body (3) and the lower body (4) comprise outer threads that are used in fixing the two bodies (3, 4) in the maxillary bone (1).
- the lower body (4) is inserted into the maxillary bone (1) and the upper body (3) is fixed to the bone fragment (2), this bone fragment (2) being the part of bone to be distracted ( separate) (said bodies (3, 4) can be seen in Figures 1 to 4).
- Both upper body (3) as the lower body (4) comprise an end zone (16) without thread, so that, once the lower body (4) and the upper body (3) are installed on the shaft (5), with the zones ends (16) of both bodies in contact, in the contact zone of the two bodies (3, 4) a free ring (12) without thread is formed.
- the free ring without thread (12) drastically reduces errors and complications that arise when facing the bodies (3, 4) one on each side of the osteotomy line (11) and that take place during placement surgery of the distractor in the bone.
- the lower body (4) and the upper body (3) comprise a female element (18) and a male element (17), which act when the two bodies (3, 4) are joined, preventing the distractor from being dismantled during its insertion in the maxillary bone (1).
- the situation of the male element (17) and the female element (18), one in the upper body (3) and one in the lower body (4), is not limiting, since it is indistinct for the upper body (3) to understand the male element (17) and the lower body (4) the female element (18) that is the other way around, and the upper body (3) comprises the female element (18) and the lower body (4) comprises the male element ( 17).
- the upper body (3) is longer than the lower body (4), thereby improving the stability of the distractor in terms of its installation in the bone fragment (2), preventing it from losing the primary stability of the upper body in the honeycomb fragment.
- the threaded shaft (5) of the device object of the invention is divided into three parts, an upper part (6) with a threaded in one direction, a lower part (7) with a threaded in the opposite direction to the thread of the upper part
- the upper body (3) comprises a through hole (13) (observable in figure 2) through which the shaft (5) passes through the end that has the concavity (9) exposing said concavity (9) so that the key (10) can be placed in said concavity (9) and the rotation of the shaft (5) can be executed.
- the upper body (3) of the device has a polygonal shape (14) around the through hole (13) at the end of the upper body (3) near the concavity (9) of the shaft (5).
- the device object of the invention works with a procedure similar to that set forth below:
- an osteotomy is performed in the maxillary bone (1), in which a bone fragment (2) is released, an osteotomy line (11) being defined that is a free zone (without bone);
- the alveolar distractor is placed, with the lower body (4) inserted in the maxillary bone and the upper body (3) fixed to the bone fragment (2), in this placement the free ring (12) without thread that is generated in the union of the two bodies (3, 4) faces the osteotomy line (11);
- the distraction of the bone fragment (2) with respect to the maxillary bone (1) begins, transmitting a rotation to the axis (5) by means of a key (10), by means of this rotation of the axis (5) the lower part is removed from the axis (7) of the lower body (4), and the upper body (3) moves along the axis (5) away from the lower body (4);
- the axis (5) is continued to rotate until the distance between the two bodies (3, 4) provides an optimum height for the placement of an implant (observable in Figure 4), the range of application of each axis rotation being (5) different according to each treatment;
