Description

[0001] The present invention relates to a patient-customized hemostatic cap for healing abutment,

 The present invention relates to a patient customized hemostatic cap for a healing abutment and a method of manufacturing the same, and more particularly to a patient customized hemostatic cap mounted on a healing abutment fastened to a fixture implanted in an alveolar bone, will be.

 In the case of a missing tooth, a bridge was used in which a denture was inserted or a surrounding portion of a tooth was used as a column and a missing portion was covered with a metal or the like. However, such a procedure has several problems, such as a denture or a bridged artificial tooth having a weak chewing force and adversely affecting surrounding teeth.

 As a result, the dental implant treatment was introduced as a result of advanced dental treatment. Such a fixture procedure forms an artificial tooth root on the alveolar bone and combines the artificial tooth, which is a final prosthesis made like a real tooth, using the tooth to obtain the effect that the patient uses the actual tooth.

 Implant surgery is divided into one-time and two-time methods. In case of one patient's alveolar bone or gum condition is good, the healing abutment is fastened on the day of implant placement.

 In the second method, after placing the implant, place a small cover screw on the upper part of the implant instead of the healing abutment, wait for several months after sewing the gum, and then anesthetize and incise the gum with a knife and tighten the healing abutment.

 The present invention relates to a hemostatic device for preventing continuation of hemorrhage in a surrounding gum after a healing abutment is fastened during a dental implant surgery procedure.

 In the case of flapless (implantless) implant surgery, a hole is formed in the gum with a punch and the implant is immediately placed without forming a valve, It is often the case that a healing abutment is concluded.

 At this time, when punching a hole in the gum, the gums may be crushed without being cleanly cut as intended. In addition, when the gums are severely damaged during the drilling process, hemorrhage occurs in the gums of the perforated holes, making it difficult to perform hemostasis.

 In this case, it is possible to perform hemostasis using gauze, but the pressure for hemostasis can not be performed smoothly due to interference with healing abutment.

 SUMMARY OF THE INVENTION The present invention was made to solve the above-mentioned problems in the prior art, and is particularly used when the length of the healing abutment exposed above the gingiva after the healing abutment is tightened is insufficient. Hemostatic cap can be used when a single implant is implanted
