Description

Gum protector

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a gum protector.

Background

Due to the high treatment success rate, dental implant restoration has become the first-choice restoration solution for patients with missing teeth. Wherein immediate implantation refers to immediate implantation of a dental implant during tooth extraction, and the treatment method can reduce the operation frequency and the operation trauma, so the method is widely favored by patients and doctors. In order to avoid alveolar bone resorption caused by conventional immediate implantation, a root shield technique has been proposed by clinical scholars, in which a part of the tooth root on the buccal side is retained to reduce buccal bone resorption, and the tooth root on the palatal side is removed and a dental implant is implanted. This technique requires trimming the remaining labial teeth 2-3mm below the gums to avoid the placement of an occlusion denture. When the dental film is trimmed, the gum is easily damaged, and the surgical complications are caused. At present, no effective protection method exists, and only the clinical experience of a doctor is relied on.
