Description

Repairing mechanism used in cooperation with dental implant

Technical Field

The utility model belongs to the technical field of dental implant, especially, relate to a repair mechanism that cooperation dental implant used.

Background

After implantation of a dental implant, the prior art has three operating solutions:

(1) for a patient with poor bone quality, the covering screw is used for closing the orifice part of the implant, so that foreign matters such as saliva and food residues in the oral cavity are prevented from entering the inner cavity of the implant to breed bacteria to cause harm to the oral health, and then soft tissues are sutured to enable the bone tissues to enter the process of long-term reconstruction.

(2) For patients with good bone quality, the healing abutment is used for closing the orifice part of the implant, preventing foreign matters such as saliva and food residues in the oral cavity from entering the inner cavity of the implant to breed bacteria and bring harm to the oral health, and then soft tissues are sutured to enable the bone tissues to enter the process of long-term reconstruction.

(3) For patients with good bone quality, the temporary abutment can be used for adhering the temporary crown to be directly arranged on the dental implant, the aesthetic requirement of immediate repair by immediate implantation is used, and then soft tissue is sutured to ensure that bone tissues enter the process of long-term reconstruction.

The technical defects of the current three technical schemes are as follows:

(1) in the second stage of repair, the product closing the opening of the dental implant needs to be removed and replaced with an abutment for permanent repair of the cemented crown. When a digital oral scan is performed, the product for closing the orifice of the dental implant needs to be detached and replaced by a scanning rod for assisting the oral scan. Both of these operations result in repeated disassembly and assembly of the product in contact with the soft tissue, causing damage to the healing surface of the soft tissue, and ultimately indirectly affecting bone resorption around the implant through the damage to the soft tissue healing.

(2) In the second stage of repair, because the product for closing the mouth of the dental implant needs to be disassembled, and because the products are small, if the experience of a doctor is insufficient, the product can be accidentally dropped into the mouth in the disassembling and assembling time, and once the product is dropped into the mouth, the product is swallowed by a patient, so that unnecessary medical accidents are caused.

(3) In the second stage of restoration, since it is necessary to replace the abutment for permanent restoration of the cemented crown, if the abutment for permanent restoration and the product for closing the opening of the dental implant used in the bone healing stage do not completely conform to each other in the transgingival contour, compression of the gum or a gap between the gums may be caused when the abutment for permanent restoration is installed. The gum compression causes discomfort to patients and even gum atrophy, and the gum clearance can cause foreign matters in the oral cavity to enter the gum, which causes adverse effects and even inflammation to the growth and healing of soft tissues.
