Description

Cheekbone threading guide plate

Technical Field

The utility model relates to the technical field of oral clinical medical surgery, in particular to a cheekbone wearing guide plate.

Background

The zygomatic bone grafting technology is proposed by a Breimark professor team of Swedish physicians in 1988, and provides a repairing mode of implant support by using zygomatic bone to implant an implant aiming at cases of serious bone defect of maxilla or alveolar bone atrophy, and the clinical planting success rate is up to 96.04%. The cheekbone-wearing implantation repair does not need bone implantation, has short healing time, can realize immediate load bearing during the implantation, and is accepted by patients in comfort, beauty and pronunciation.

The zygomatic surgery is a surgical operation that after a long implant with a specific model enters from an alveolar bone, the implant upwards and outwards passes through a maxillary sinus partially or completely, the root of the implant is positioned at the zygomatic bone, facial nerves and vascular tissues at the position are dense and complex and are very easy to damage, the length of the implant is 3-5 times as long as that of a conventional implant, and the extremely small angle deviation of the starting end can cause great deviation of the tail end, so that the risk of penetrating into a nasal sinus, an orbit and the like is caused.

In view of this, the present invention aims to provide a zygomatic guide plate which can perform a precise positioning function in the zygomatic operation, reduce the operation error, and improve the treatment effect.

In order to solve the technical problems, the technical scheme of the utility model is as follows: a cheekbone threading guide plate comprises an alveolar bone in-place bottom support, a cheekbone in-place guide plate arranged on the alveolar bone in-place bottom support, an alveolar bone approach guide tube arranged on the alveolar bone in-place bottom support and a cheekbone approach guide plate arranged on the cheekbone in-place guide plate, wherein the axis of the alveolar bone approach guide tube and the axis of the cheekbone approach guide tube are positioned on the same straight line.

Preferably, the cheekbone positioning guide plate is detachably connected with the alveolar bone positioning bottom support.

Furthermore, a groove is formed in the outer surface of the alveolar bone in-place bottom support in an inward concave mode, an extension arm is arranged outside the cheekbone in-place guide plate in an extending mode towards the direction of the alveolar bone in-place bottom support, and a protruding block which is correspondingly matched with the groove is arranged at one end, far away from the cheekbone in-place guide plate, of the extension arm.

Preferably, the alveolar bone approach guide pipe and the alveolar bone in-place bottom support are integrally formed.

Preferably, the zygomatic bone access guide tube and the zygomatic bone positioning guide plate are integrally formed.

Preferably, the zygomatic bone positioning guide plate is provided with three retention holes.

The technical effects of the utility model are mainly embodied as follows: can guide the trend of location drill point from alveolar bone to zygomatic bone through alveolar bone admission stand pipe and zygomatic bone admission stand pipe to can be in the surgery and be equipped with the hole after, to implant the effect that plays accurate positioning, reduce the operation error, improve treatment.

Detailed Description

The following detailed description of the embodiments of the present invention is provided in order to make the technical solution of the present invention easier to understand and understand.

In the present embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right", "left", "above", "back", "middle", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention, and do not indicate or imply that the referred devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the present embodiment, if the connection or fixing manner between the components is not specifically described, the connection or fixing manner may be a bolt fixing manner, a pin connecting manner, or the like, which is commonly used in the prior art, and therefore, details thereof are not described in the present embodiment.

A cheekbone passing guide plate is shown in figures 1-4 and comprises an alveolar bone positioning bottom support 1, a cheekbone positioning guide plate 2, an alveolar bone approach guide pipe 3 and a cheekbone approach guide plate 4, wherein the alveolar bone approach guide pipe 3 is formed by a smooth cambered surface on the outer side, the inner side of the alveolar bone positioning bottom support is matched with the occlusal surface of teeth, the alveolar bone approach guide pipe 3 is arranged on the alveolar bone positioning bottom support 1, the cheekbone approach guide plate 4 is arranged on the cheekbone positioning guide plate 2, and the axis of the alveolar bone approach guide pipe 3 and the axis of the cheekbone approach guide pipe 4 are positioned on the same straight line.

In the embodiment, the zygomatic bone positioning guide plate 2 is detachably connected with the alveolar bone positioning bottom support 1.

Specifically, a groove 11 is concavely arranged outside the alveolar bone in-place bottom support 1, an extension arm 21 is arranged outside the zygomatic bone in-place guide plate 2 in a manner of extending towards the direction of the alveolar bone in-place bottom support 1, and a protrusion 22 correspondingly matched with the groove 11 is arranged at one end of the extension arm far away from the zygomatic bone in-place guide plate 2. The groove 11 is not communicated with the tooth fixing groove on the inner surface of the alveolar bone in-place bottom support 1.
