Description

Detachable shortened planting system and using method

Technical Field

The invention relates to a detachable shortened planting system and a using method thereof, belonging to the technical field of oral medical instruments.

Background

With the continuous development of the oral implantation technology, the technology of artificial tooth implantation gradually matures and is stable. The artificial tooth implantation is that the titanium artificial tooth root with high biocompatibility is firstly placed into the tooth socket for fixation and suture, and after several months, the artificial tooth root is firmly connected with the bone in the tooth socket, and then the subsequent false tooth installation is carried out. The artificial tooth root of the artificial tooth implant is directly connected with the bone, can provide better supporting force and is popular because the artificial tooth root can chew harder food. Among them, whether the artificial tooth can be effectively used for a long time after being implanted is one of the most concerned problems.

The implant part of the existing artificial tooth implant is of a one-stage type, and the operation mode is as follows: preparing holes step by step, screwing the implant into the alveolar bone, fixing the abutment to the implant through screws according to the treatment time period standard, and installing false teeth on the abutment to restore physiological functions and meet the aesthetic requirements.

The smoking people are easy to suffer from periodontitis or gingival atrophy diseases, once a certain amount of gingival atrophy occurs, if the gingival atrophy treatment is not timely treated or is not successful, the implant part of the implant is exposed and even falls off, and in order to ensure the stability and usability of the implant, the implant needs to be taken out and planted again. This results in long planting cycle, high wound and high cost.
