Description
Technical Field
The utility model relates to a model, in particular to a periapical lesion microsurgery model for skill training.
Background
Periapical disease is a common lesion of the oral maxillofacial region, and is a disease occurring in tissues around the apex of the tooth, such as cementum, periodontal ligament around the apex, alveolar bone, etc., due to various causes. They are roughly classified into acute periapical inflammation, chronic periapical inflammation and periapical cyst. The pathological anatomical features of acute periapical inflammation are the accumulation, transformation, diffusion or absorption of periapical exudates, and most of the pulp has necrosis except for acute periapical inflammation caused by some trauma. The pathological anatomical features of chronic periapical inflammation are the proliferative inflammatory changes of periapical tissue, i.e. the formation of fibrous and gingival tissues, and the morphological changes of periodontal ligament spaces. Periapical cysts are periapical lesions surrounded by granulation tissue, lined with epithelium. When the cyst is enlarged, peripheral bone substances are absorbed by compression, and root of tooth is absorbed by compression of adjacent teeth.
The micro apical surgery is an oral surgery mode for amplifying the oral surgery visual field by using a root canal operation microscope, treating and repairing the affected tooth and the lesion area thereof, can carry out surgical exploration operation on a fine and complex structure, and accurately estimates and removes the lesion tissue without damaging the normal tissue. Meanwhile, the cure rate and success rate of the intractable periapical periodontitis and apical cyst can be effectively improved.
At present, in teaching practice, laboratory simulation head model teaching is the most common teaching form and is widely applied to conventional preclinical teaching of dental endodontics. The models commonly used at present are an animal skull model and an in vitro dental plaster model. The animal skull model can well simulate root tip scaling and bone surface treatment, but has the defects of peculiar smell, larger morphological difference with human teeth, poor simulation of root tip excision and inverted filling, and incapability of being used for oral operation. The in vitro tooth plaster model has good root tip excision and inverted filling simulation, can be assembled on a simulation head model for operation, but has no simulation operation of soft tissue operation, and the in vitro tooth has a short source and poor standard.
