Description

Healing cap, components of healing cap and method of selection thereof

technical field

The present invention relates to a healing cap, a healing cap assembly and a selection method thereof, in particular to a healing cap, a healing cap assembly and a selection method thereof controlled by a special positioning structure and a corresponding auxiliary tool.

Background technique

Artificial teeth are one of the methods commonly used in the treatment of missing teeth. Different from the previous dentures, which have the disadvantages of poor chewing, low stability, unsightly appearance, and must have the support of adjacent teeth, artificial teeth can improve the previous dentures. It looks very much like your own original teeth and is highly stable, so you can chew all kinds of food with peace of mind. In addition, artificial dental implants have the advantages of not needing the support of adjacent teeth and having a high success rate of surgery, so as long as they are properly maintained, they can be used continuously for a long time.

The traditional artificial dental implant surgery can be divided into two types, one is a one-piece dental implant, which first implants the implant into the alveolar bone in the edentulous area, and then connects the implant to the abutment tooth to make the abutment tooth Exposed gums. After several months, the implants and abutment teeth are integrated with the alveolar bone to form the pillar of the denture, then the temporary crown and denture impression are made, and finally the denture is fitted on the abutment teeth to complete this stage Dental implant surgery. However, after the implant is implanted in this dental implant method, the wound is not sutured, so the wound will continue to bleed or ooze after the operation. The space between the gums often accumulates residues after meals, and it is not easy to clean, so it is easy to cause wound inflammation and other phenomena. Moreover, after the wound heals, the gingival contour that originally conformed to the shape of the tooth is often destroyed, making it inconvenient to make a temporary crown. Therefore, anesthesia is required before implanting the denture to expand the soft tissue of the gingiva, which will cause discomfort to the patient.

Another way is the two-stage dental implant. The first stage is to implant the implant into the gingival bone of the edentulous area, but the abutment tooth is not installed but a healing cap is installed during the implantation. After a few months, the implant is integrated with the gingival bone, and then the second stage of surgery is performed to remove the healing cap, so that the implant can be connected to the abutment tooth and the crown. The above-mentioned healing cap is usually cone-shaped or screw-shaped, and its main purpose is to heal the gingival tissue according to the shape of the healing cap, or to maintain enough space for placing the final restoration. Most of the healing caps currently used in the market are made of titanium metal and are conical. However, because titanium metal is not easy to repair and the cost is high, the cost of dental implants is likely to be too high and not ideal. In addition, titanium metal is often recycled and reused, which is prone to cross-infection problems. Furthermore, conical healing caps are not suitable for dental implants at all tooth positions. The main reason is that different tooth positions have different gingival tissue, tooth shape and structure, and environmental conditions and requirements of adjacent teeth. It can be seen that there is currently a lack of a low-cost, easy-to-install and dismountable healing cap, healing cap components and selection methods that can be adapted to various tooth positions in the market, so all related companies are looking for a solution.

The displacement abutting portion 520 can be rotated by a rotating tool (not shown in the figure) to displace the displacement abutting portion 520 downward, that is, in the negative Z-axis direction. In addition, when the screw thread portion 510 is screwed into the screw hole 1042, the lower edge of the displacement abutment portion 520 will be tightly abutted against the intersection entity between the first space 312 and the second space 314, thereby making the end surface 1044 of the implant 104 tight. The bottom surface 340 of the body 300 is engaged. The rotating tool corresponds to the hexagonal hole 522 of the displacement abutting portion 520 , and since the rotating tool is a generally known technology, its details will not be repeated here. It is worth mentioning that when removing the healing cap 200 , the medical personnel can first use the auxiliary tool 102 to fix the positioning structure 400 of the healing cap 200 , and then turn the fastening member 500 away and disassemble it through the rotating tool. Next, the medical staff vertically displaces the healing cap 200 upwards, that is, pulls it up in the direction of the positive Z axis, so that the healing ring surface 320 is separated from the gum. However, under the condition that the healing cap 200 of the present invention has a positioning structure 400 and a specific tapered healing ring surface 320, the rotation and pulling between the healing ring surface 320 and the gum can be effectively avoided, and the degree of damage to the separated gingiva can be greatly improved. However, when the known single cone-shaped healing cap structure is disassembled, it is easy to cause the rotation and pulling of the healing ring surface and the gum to enlarge the wound. Therefore, the healing cap 200 of the present invention is quite helpful to the patient.

In addition, the material of the healing cap 200 of the present invention can be medical grade plastic, medical grade pure titanium, titanium alloy, glass ceramics, feldspar, zirconia, precious metal or non-precious metal. Among them, medical grade plastics can be polymethyl methacrylate (PMMA) or polyether ether ketone (PEEK). Precious metals can be high-gold alloys (containing more than 70% gold, palladium, and platinum), low-gold alloys (containing gold, palladium, and platinum between 45% and 60%), palladium-silver alloys, or alloys for ceramic fusion metals. The non-noble metal can be cobalt chromium, cobalt chromium nickel or nickel chromium. Manufacturers can determine the material of the healing cap 200 based on requirements.
