AI Technical Summary
Existing methods for treating gum recession, such as free gingival grafting, suffer from complications like prolonged intra- and postoperative bleeding, infection risk, and discomfort due to damage of palatine vessels during autograft harvesting from the palate, necessitating improved techniques for safe and comfortable patient rehabilitation.
A method involving the use of a hemostatic composition of aluminum chloride hexahydrate, iron chloride hexahydrate, and octenidine dihydrochloride, applied to a sterile gauze pad, is used to achieve local hemostasis and tissue regeneration, secured with sutures and medical glue, followed by a follow-up examination to ensure wound healing.
This approach effectively minimizes bleeding, ensures safe wound healing, and reduces patient discomfort by stabilizing the wound surface, promoting tissue regeneration and preventing infection.
Abstract
Description
[0001] The invention relates to surgical dentistry and can be used for comfortable and safe rehabilitation of a patient after plastic surgery of soft tissues of the oral cavity with the collection of an autograft from the palate.
[0002] Gingival recession is defined as the apical displacement of the gingival margin toward the cementoenamel junction and affects almost all middle-aged and older adults to varying degrees. This leads to root exposure, which in turn causes clinical problems such as hypersensitivity, root caries, plaque removal difficulties, unattractive aesthetics, etc.
[0003] Currently, gum recession can be treated with periodontal plastic surgery. The ultimate goal of periodontal procedures is complete root coverage, which leads to good aesthetic results. The most classic clinical procedure in mucogingival surgery is free gingival grafting. Free gingival grafting is also widely used to increase the size of attached gingiva.
[0004] However, most complications following this procedure are related to underestimation of anatomical structures, such as the greater palatine artery. Regardless of the method of harvesting the graft from the palate, prolonged intra- and postoperative bleeding caused by damage to the palatine vessels is one of the most common complications of this procedure. There is also a risk of infection of the wound surface at the donor site.
[0005] Therefore, there is a need to find the most effective way to stop bleeding from the palatal donor site. Minimizing discomfort in the graft harvesting area and ensuring safe patient rehabilitation during the postoperative period also remains essential.
[0006] A method is known for stopping bleeding from the vessels of the mucous membranes (RU 2104068 dated 02 / 10 / 1998) using the radiation of a YAG-NO laser from the working end of the light guide to the surface of the mucous membrane.
[0007] The disadvantages of this technique are the risk of late bleeding if the area is injured while eating, as well as discomfort for the patient with each act of swallowing, when the tongue will be in direct contact with the wound surface.
[0008] An analogue, closer to the invention (its prototype), is the method of closing a donor wound on the palate when collecting a free gingival graft according to Edranov using a multifunctional non-contact plasma high-voltage coagulator (RU 2754062 dated 08 / 25 / 2021).
[0009] The well-known technique involves treating the soft tissue defect formed after harvesting a multilayer autograft and using a material that stimulates tissue regeneration; however, the use of a multifunctional non-contact plasma high-voltage coagulator and a protective cap complicates the operation.
[0010] The invention is aimed at solving the technical problem of eliminating the shortcomings of known methods for rehabilitating the wound surface of the donor area of the palate.
[0011] The technical result of the invention is to ensure comfortable and safe rehabilitation of the patient after the removal of an autograft from the palate.
[0012] The essence of the invention is expressed in a set of essential features, in which the method for rehabilitation of the wound surface of the donor area of the palate, including the treatment of a soft tissue defect after collecting a multilayer autograft and the use of a material that stimulates tissue regeneration, differs from the closest analogue in that for local hemostasis and stimulation of tissue regeneration, a hemostatic composition is used in the form of a solution of a mixture of salts of aluminum chloride hexahydrate and iron chloride hexahydrate, and octenidine dihydrochloride is used as an antiseptic, while a sterile gauze napkin is impregnated with the solution and antiseptic, the length and width of which are 3-5 mm greater, respectively, than the length and width of the soft tissue defect, the gauze napkin is placed in the soft tissue defect and fixed with 2-4 wrapping sutures, and medical glue "Sulfacrylate" is applied to the line of intersection of the sutures and the sterile gauze napkin.
[0013] After anesthesia and creation of the recipient bed, a free gingival graft is collected.
[0014] To stimulate tissue regeneration, stop bleeding from the donor site of the hard palate, and protect it from infection, use a sterile gauze pad impregnated with a hemostatic composition consisting of a solution of aluminum chloride hexahydrate, iron chloride hexahydrate, and octenidine dihydrochloride, which is used as an antiseptic. The length and width of the gauze pad are 3-5 mm greater than the length and width of the soft tissue defect, respectively. The gauze pad is placed into the soft tissue defect and secured with 2-4 wrapping sutures. Sulfacrylate medical adhesive is applied to the intersection of the sutures and the sterile gauze pad.
[0015] Then the doctor continues with the main procedure. On the 7th day, the patient returns for a follow-up examination, where the doctor removes the sutures, removes the dressing, and inspects the wound surface to ensure the blood clot has stabilized in the donor area and the wound is healing.
[0016] Example 1.
[0017] Patient K., 22, was referred by an orthodontist for treatment of gingival recession in the area of teeth 1.5 and 1.4 following orthodontic treatment. After examination, it was decided to eliminate the recession using a tunnel method. Using a microsurgical scalpel and special curettes, a tunnel was created in the area of teeth 1.3-1.6. An autograft was collected from the right palate, taking into account the length and width of the exposed tooth necks. A sterile gauze pad soaked in a hemostatic composition in the form of a mixed solution of aluminum chloride hexahydrate, iron chloride hexahydrate, and octenidine dihydrochloride was placed into the resulting soft tissue defect on the palate, and three encircling sutures were placed. Sulfacrylate glue was placed at the intersection of the sutures and the gauze pad. The patient returned for a check-up a week later. The doctor removes the stitches and examines the wound. The wound is in the epithelialization stage. The patient reports no discomfort during recovery.
[0018] Example 2.
[0019] A patient was referred to the clinic for the extraction of tooth #3.6 with immediate implant placement. The tooth was segmented and extracted, and an implant was placed in the interradicular septum. A healing abutment was placed. A free gingival graft was collected from the right palate for soft tissue grafting in the implantation area. A sterile gauze pad soaked in a hemostatic solution consisting of a mixed solution of aluminum chloride hexahydrate and iron chloride hexahydrate salts, along with an antiseptic compound (octenidine dihydrochloride), was placed in the donor area. Two serrated sutures were placed to secure the gauze pad. Sulfacrylate adhesive was applied along the suture and pad border. Hemostasis was achieved. The patient returned for a follow-up examination a week later. The doctor removed the sutures and the gauze pad. The wound is clean, without signs of inflammation, and is in the epithelialization stage.
