Background
In cases of natural peri-dental recession of the gingiva, insufficient peri-implant keratinized gingiva, etc., periodontal and peri-implant inflammation may be caused, resulting in early teeth and implant failure. Cornified gum broadening is an effective solution to the above problem. Autologous free gum grafts taken from the hard palate are the gold standard for keratinized gum widening. Currently, for obtaining the keratinized gum on the hard palate part, a 15# blade is conventionally used for stripping to obtain a flaky keratinized gum with the thickness of 1.5mm, the width of 8mm and the length of 10-30 mm. Since there is more bleeding during the process of obtaining the cornified gum, the surgical field of the physician is affected, and even an experienced physician needs about 4-6min for the operation time. Moreover, the thickness of the graft is critical to the effect of the surgery. Too thick a graft with deep fat and glands often requires removal, increases surgical time, and increases post-operative discomfort, and too thin a graft makes it less viable. Therefore, the problems facing the clinical access to the hard palatal keratosis gingiva currently are: 1) poor visual field and difficult operation; 2) the thickness is not uniform, and the effect after operation is influenced; 3) the operation time is long, the amount of bleeding is large, and the discomfort of the patient after the operation is increased.
