In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings, which are illustrated in the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

Some embodiments according to the invention are described below with reference to fig. 1 to 7.

Example 1

Referring to fig. 1 and 2, an embodiment of the present invention provides a maxillary sinus external lifting guide 30, including: a plurality of fixing parts 10, wherein the lower side of the fixing part 10 is provided with a connecting cavity 20, and teeth at least one side of the front and back of the gap can be embedded into the corresponding connecting cavity 20, so that the fixing part 10 is fixed with the teeth; and a lifting guide plate 30 fixed to the outer side wall of the fixing portion 10, the lifting guide plate having a window guide hole 31.

In this scheme, through setting up the fixed part 10 fixed with the tooth, it is convenient to install, and the location is accurate simultaneously, can also reduce the volume, reduces the operation degree of difficulty, and it is convenient to use.

Referring to fig. 1 to 4, in a preferred embodiment, the fixing portion 10 includes: the first fixing portion 11 and the second fixing portion 12 are respectively disposed at two sides of the gap, and the first fixing portion 11 and the second fixing portion 12 are both provided with a connecting cavity 20.

The number of the first fixing portions 11 is two, and three teeth can be used as a fixing unit, so that the connection stability can be improved, and the positioning accuracy can be improved.

In a preferred embodiment, the connecting cavity 20 is adapted to the shape of the tooth.

In the scheme, the connecting cavity 20 is matched with the shape of the tooth, so that the fixing reliability can be improved, and looseness can be prevented.

In one embodiment, before the maxillary sinus external lifting guide 30 is manufactured, a preoperative process is first performedCone-shaped operation Radiation computer controlled tomography (CBCT) measurement analysisThe patient is planted and takes the plaster model of the upper and lower jaw dentition after shooting the curved surface broken layer sheet for preliminary evaluation, and in order to ensure the quality of the plaster model, the super hard plaster is poured by taking the silica gel mould. The patient then takes CT or CBCT of the jaw bone and reads DICOM data as required by the simplan software.

DICOM data of a patient are input into a computer to carry out three-dimensional reconstruction and extract information such as bone tissues, maxillary sinuses, mandibular nerve canals and the like. And then, acquiring the information of the restored teeth and mucosa on the plaster model by adopting a high-precision three-dimensional optical scanner, replacing the tooth information on the CT data with the accurate information on the plaster model by adopting an information fusion technology to generate a full-information model, and carrying out oral implant surgery design (CAD) by simulating the prosthesis on the upper part of the implant. During the period, the operator and the repairing doctor of the software carry out repeated communication and negotiation, and finally, the position of the maxillary sinus external elevation fenestration and the positions and angles of the implant and the abutment thereof are accurately positioned. The size of the pilot hole is designed according to the planting scheme designed by the operator (according to the pioneer navigation or the whole-course navigation).

The lifting guide plate 30 is made by laser scanning resin rapid molding equipment by adopting SLA (stereo lithography) rapid molding technology, is a mature rapid molding process at present, has high dimensional accuracy, and can ensure that the dimensional accuracy of a workpiece is within 0.1 mm. The plate is made of medical resin and accords with biological safety.

The lifting guide 30 retains at least three teeth as a retention unit. The elevator guide 30 covers the occlusal surface, the lingual half and the lateral wall of the maxillary sinus of the tooth and marks the site to be windowed (e.g., a fenestration range of 7 x 10 or 7 x 13).

Among them, the type of the lifting guide 30 may be one of a full navigation digital surgical guide, a one-way navigation digital surgical guide, a dental support type implant guide 40, and a mucosa support type implant guide 40.

In an alternative embodiment, a plaster model of the oral cavity of the patient is first taken, a model of the part where the dental implant of the patient is to be implanted is made by the plaster model, and the influence of the mucosa on the positioning error is taken into consideration, so that after the model of the part where the dental implant of the patient is to be implanted is made, the corresponding part of the mucosa is ground to remove the part corresponding to the thickness of the mucosa, and then the lifting guide plate 30 is made according to the made model of the part where the dental implant is to be implanted. Since accurate information of bone tissue can be obtained during CBCT, the influence of mucosa does not need to be considered.

Example 2

Referring to fig. 3 and 4, the present embodiment is different from embodiment 1 in that the maxillary sinus outer lifting guide 30 further includes: the planting guide plate 40 is fixedly connected with the fixed upper side, the planting guide plate 40 is positioned on the upper side of the gap, and a planting guide hole 41 is formed in the planting guide plate 40; the planting guide tube 50 is inserted into the planting guide hole 41 from top to bottom, and the planting guide tube 50 is clamped with the upper end face of the planting guide plate 40.

When the height of the residual alveolar bone of the patient is more than 3mm (namely, the implant can be stabilized by the residual bone quantity), the implant can be implanted while the implant is lifted, if the height of the residual alveolar bone of the patient is less than 3mm, the bone grafting material is implanted firstly, and the implant operation is performed after bone formation.

This scheme is applicable to when patient's surplus alveolar bone height is greater than 3mm (remaining bone volume can make the planting body firm promptly), this moment, through setting up and promoting the integrative planting baffle 40 of baffle 30, can once install the baffle and accomplish the implantation of the outer promotion of maxillary sinus and planting body simultaneously, easy operation can improve operation efficiency, shortens patient's operation time.

Referring to fig. 3 and 4, in a preferred embodiment, the planting guide 40 is fixedly coupled to the lifting guide 30.

In this scheme, plant baffle 40 and promote baffle 30 fixed connection, can improve bulk strength, can reduce deformation to improve the precision.

Example 3

Referring to fig. 5, the present embodiment is different from embodiment 1 in that the fixing portion 10 is located at one side of the gap, and at least two teeth at one side of the gap are inserted into the connection cavity 20.

In the scheme, the fixing part 10 is positioned at one side of the gap, and at least two teeth at one side of the gap are embedded into the connecting cavity 20, so that the positioning can be completed when the operation space is insufficient or no qualified teeth are available at one side of the gap.

Example 4

Referring to fig. 6 and 7, the present embodiment is different from embodiment 3 in that the maxillary sinus outer lifting guide 30 further comprises: the planting guide plate 40 is fixedly connected with the fixed upper side, the planting guide plate 40 is positioned on the upper side of the gap, and a planting guide hole 41 is formed in the planting guide plate 40; the planting guide tube 50 is inserted into the planting guide hole 41 from top to bottom, and the planting guide tube 50 is clamped with the upper end face of the planting guide plate 40.
