Composite base table assembly

Abstract

The invention discloses a composite base table assembly, which comprises a substrate, a substrate screw, a base table and a base table screw, wherein the substrate is fixed to a planting body throughthe substrate screw; the base table is arranged on the substrate through the base table screw; the lower part of the base table screw is connected with the upper end of the substrate screw through screw threads. The base table assembly is formed through the substrate, the substrate screw, the base table and the base table screw; the problem of non-adjustable base table position due to different implanting depth of planting bodies can be solved. The substrate is made into a reverse cone frustum structure, and helps the tissue formation in the postoperative healing period; a gum cuff matched with a gum curve of the patient is formed. Through the arrangement of a healing cap, an operation passage is reserved for the subsequent substrate replacement on the premise of isolating the bacteria andpreventing infection; the secondary harm to the gum caused by the substrate replacement is avoided; meanwhile, the entering of the bacteria into the alveoli fossa is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of oral implantation, in particular to a composite abutment assembly. Background technique [0002] Since the early 1980s, dental implantology has opened up a new field for dental implantology. Implant restoration has become a rapidly developed and reliable restoration method, and has gained an important position in the field of stomatology. Dental implants, as artificial tooth roots for denture retention devices, have been widely used in the restoration of single tooth defects, partial tooth defects, and complete tooth loss in the oral cavity. [0003] At present, there are many types of abutments, but there are still many problems and there is a lot of room for improvement. For example, different abutments need to be replaced during the operation, which is cumbersome for the doctor to operate, the comfort of the patient is poor, and the doctor's work intensity is high. At the same time, when replacing th...

Problems solved by technology

[0003] At present, there are many types of abutments, but there are still many problems and there is a lot of room for improvement

For example, different abutments need to be replaced during the operation, which is troublesome for doctors to operate, less comfortable for patients, and higher work intensity for doctors

At the same time, when replacing the abutment, the size of different abutments is different, and the gums need to be damaged twice before the abutment can be replaced. For patients with thin gums, the stability and repairability are worse.

In addition, the end of the gingiva has a circular arc structure, and there is a large gap between it and the abutment, and the wrapping ability of the gingiva to the abutment is not strong
