Description

Surgical suture fixing device for widening cornified tissues and using method

Technical Field

The invention relates to a surgical suture fixing device for widening keratinized tissues and a using method thereof, belonging to the technical field of medical equipment.

Background

With the increasing improvement of the planting technology, the planting repair is gradually the first choice for repairing the dentition defect and the dentition deficiency patient. Although some studies report that the long-term success rate of the implant can reach 90-95%, various biological and aesthetic complications still occur in clinic. In recent years, the importance of peri-implant keratinized tissue to maintain long-term implant health has been receiving attention.

The compact cornified tissue structure is beneficial to daily cleaning of the implant and can resist various mechanical injuries, and meanwhile, as a part of attached mucous membrane, the cornified tissue can resist the traction effect generated during chewing and lip movement and limit the progress of inflammatory reaction to the root direction.

Clinical studies have shown that sufficient keratinized tissue can better maintain the health of soft and hard tissues around the implant, while insufficient width of keratinized tissue around the implant (KW) can lead to more soft tissue retraction and to an increase in indices of inflammation of soft tissues around the implant, such as plaque index, gingival index, exploratory bleeding, etc. Furthermore, the keratinized tissue of sufficient width facilitates the removal of plaque from the patient on a daily basis, and alleviates the discomfort associated with cleaning implants caused by the lack of keratinized tissue.

At present, the operation for widening the keratinized tissue is to suture and fix the suture on the periosteum, the operation difficulty is high, the suture is easy to slip, and the widening effect of the keratinized tissue is poor.
