Description

Auxiliary tool in cheekbone-wearing planting operation

[ technical field ] A method for producing a semiconductor device

The utility model belongs to the technical field of medical instrument, specifically indicate an appurtenance in the operation is planted to cheekbone.

[ background of the invention ]

With the loss of more and more people, the implanted teeth gradually red in various networks and oral hospitals as the internationally recognized 'third pair of human teeth', and various publicity is also in endless. More and more people begin to receive the dental implant and feel the benefits brought by the dental implant.

However, although the dental implant is well repaired, not everyone can achieve the conditions of dental implantation, such as serious alveolar bone resorption or osteoporosis, and it is very difficult to implant the dental implant. The more advanced method in clinic is a zygomatic bone fixing implant technology, which can better solve the problem of the planting effect which cannot be achieved by conventional planting, and is called as zygomatic planting or soilless culture technology.

The cheekbone-penetrating implantation is a technique for fixing implant teeth through cheekbones, which is also a difficult implantation technique at present, and is to implant a specific implant into the rhombic cheekbones positioned outside and below the orbit of a human eye. Generally, a heavy jaw bone absorptor needs 2 zygomatic implants, and 23 common implants are vertically implanted in the anterior tooth area to achieve a better retention effect in the semi-oral tooth restoration, as shown in fig. 1. For patients with very severe jaw resorption, four zygomatic implants may be used for retention implantation. The technique is suitable for the edentulous jaw patients who have no way to achieve the planting condition in conventional bone grafting and internal and external lifting because the maxillary bone is resected and seriously atrophied, the bone quantity is very little. The cheekbone-passing planting method has the advantages that additional operations such as bone taking and bone grafting are avoided, fixed teeth can be worn in a short time on the day of planting, immediate load bearing can be achieved, and treatment time is greatly shortened. The method is an effective replacement treatment method under the condition of severe maxillary bone absorption, can also be used for repair treatment of maxillary defects, avoids a large number of bone grafting operations, and can obviously shorten the period of planting treatment.

Although the cheekbone planting technology has obvious advantages, the difficulty is very high, the used implant is 3-4 times of the traditional implant, and therefore a small error can cause the serious deviation of the tail end. The adjacent arteries, veins and nerves in the surgical field must be understood in detail, and once damage is done to these anatomical structures, various complications may result, such as ocular damage or nerve-related dysfunction.

At present, the cheekbone planting is carried out by domestic oral institutions rarely, the cheekbone planting technology has extremely strict requirements on software, hardware and doctors, a stereoscopic support guarantee degree is required to be provided by a professional oral CBCT, a detailed operation plan is required before an operation, the conditions of bilateral cheekbones are required to be known, conventional special examinations of the whole body and the oral maxillofacial region are required to be carried out, the existence of related contraindications is eliminated, and the smooth implementation of the planting operation can be ensured.

At present, only a few doctors operate the cheekbone planting operation in China, and the doctors operating the cheekbone planting operation all operate by moving hands, when a planting hole is prepared, a drill needle penetrates a maxillary sinus mucosa and is easy to lacerate, and operation complications such as inflammation and the like can be caused. When the planting hole preparation is carried out manually, human deviation is easy to generate, and finally, the planting position of the implant is inconsistent with the planned position (optimal position).

[ Utility model ] content
