Description

Dental Implant

technical field

The utility model relates to a dental implant, in particular to a miniature dental implant used when alveolar bone atrophy is caused by surgical treatment of teeth, and the height or width of the alveolar bone is insufficient.

Background technique

Dentures can be used to fill the gap when teeth are extracted due to tooth decay, broken teeth, or periodontal disease. The traditional filling is to grind down the healthy teeth on both sides of the missing tooth, and then cast a set of braces. However, the use of braces tends to make the adjacent teeth tilt and accumulate food debris, which can lead to bacteria. However, those who are completely edentulous or have no teeth in the back molars use movable dentures that are completely supported by the mucous membrane of the gums, so they cannot bite hard things. Therefore, in order to improve the inherent shortcomings of traditional dentures, modern technology-based dentistry has developed "artificial implants" to solve the problem of patients with missing teeth wearing traditional dentures.

The known artificial tooth implant is to transfer the artificial tooth root between the alveolar bones in the edentulous area, and after the artificial tooth root and the alveolar bone are closely combined, a false tooth with a column core is installed thereon. However, this kind of artificial tooth is only suitable for use when the alveolar bone does not atrophy after the tooth is surgically treated. When the alveolar bone atrophy, another form of dental implant, that is, "mini-implant" needs to be used. The mini-implant combines the artificial tooth root and the core of the tooth column, and is formed in one piece. The current mini-implant is set with a smooth thread on the artificial tooth root, and the core of the tooth column is in a cylindrical shape, which is used for auxiliary equipment to insert the mini-implant Screw and lock into the alveolar bone. Due to the setting of the smooth surface screw thread at the artificial tooth root place at present, the phenomenon that the auxiliary instrument often occurs when the operation is inserted is idling.

Contents of the invention

In view of the above problems, the main purpose of the present invention is to provide a dental implant which can avoid the disadvantages in the operation of the current dental treatment.

In order to achieve the above purpose, the utility model adopts the following technical solutions: a dental implant, which is a mini implant combined with an integrally formed artificial tooth root and a tooth column core, and a screw thread is provided at the artificial tooth root; it is characterized in that : The artificial tooth root with threads is treated with rough surface threads.

The rough thread treatment method at the artificial tooth root is sand blasting, sand blasting plus acid etching, anodic oxidation or biological auxin additives.

The utility model can also adopt another technical solution: a dental implant, which is a mini implant combined with an integrally formed artificial tooth root and a tooth column core, and a screw thread is provided at the artificial tooth root; it is characterized in that: The threaded artificial tooth root is a sharp self-tapping shape with a downward taper.

The threads at the artificial tooth roots are set to the same tooth depth.

The thread at the artificial tooth root is set to have alternate tooth depths.

More than one plane is arranged at the center of the tooth column of the dental implant.

The other side of the plane at the center of the tooth column is provided with a groove.

A hexagonal protruding section is arranged at the center of the tooth column of the dental implant, and a spherical part with a neck extends from it.

By adopting the above-mentioned technical scheme, the utility model has the following advantages: 1. The artificial tooth root of the mini-implant adopts a sharp self-tapping shape with a downward shrinking "taper", which can avoid excessive pressure in the blood clot when the implant is placed, resulting in insertion difficulties. 2. The artificial tooth root of the mini-implant adopts a sharp self-tapping shape with a downward shrinking "taper". When the alveolar bone is soft, the pre-tapping operation can be omitted, and the artificial tooth root with sharp self-tapping threads can be used. Insert directly into the hole. 3. The artificial tooth root of the mini-implant is treated with rough surface threads, which can improve the degree of integration between the artificial tooth root and the alveolar bone, thereby prolonging its service life. 4. The artificial tooth root of the mini-implant is firmly and tightly combined with the alveolar bone, so that the single denture, full denture and movable denture on the center of the tooth column can have the same chewing function as real teeth. 5. The center of the tooth column of the mini-implant adopts more than one plane or a hexagonal protruding section, which can make the inner hole of the auxiliary device fit stably, and the phenomenon of auxiliary device idling will not occur.

Detailed ways

In order to describe the structure, features and effects of the present utility model in detail, the following preferred embodiments are given below together with the accompanying drawings.

The dental implant provided by the utility model, as shown in Figure 1 and Figure 2, is a mini implant combined with an integrally formed artificial tooth root and a tooth column core, wherein:

The artificial tooth root 11 of the mini-implant 1 adopts a downwardly contracting taper, which is a sharp self-tapping shape, and is treated with a rough surface thread. In addition, at least one plane 121 is arranged at the 12 places of the tooth column center, and the 12 places of the tooth column center are provided with at least one plane 121. The other side of the plane 121 is provided with a groove 122 for stably fitting the inner hole of the auxiliary device, so that the auxiliary device does not spin idle. The rough surface thread processing method at the artificial tooth root 11 of the utility model can adopt known methods such as sand blasting, sand blasting plus acid etching, anodic oxidation or biological auxin additives.

The mini implant 1 of the present utility model can be applied to a single denture 2, as shown in Figure 3, or to a full denture 3 and a movable denture, as shown in Figure 4, when the utility model is applied to a full denture 3, it is Coat several magnet sets 32 between the alveolar bone and the gingiva 31 of the full denture 3, and then screw and lock several mini-implants 1 corresponding to the positions of the magnet sets 32 into the space between the alveolar bone and the gingiva 4, and make The 12 cores of the teeth are exposed, and then the full denture 3 is directly pressed on the gum 4, and the magnet set 32 of the full denture 3 is adsorbed and positioned with the core 12 of the mini implant 1 to achieve a stable fit.
