Embedded tooth individualized bone fenestration guide plate based on three-dimensional printing technology

Abstract

The invention relates to the technical field of medical treatment, in particular to an embedded tooth individualized bone fenestration guide plate based on a three-dimensional printing technology. Theembedded tooth individualized bone fenestration guide plate based on the three-dimensional printing technology adopts the three-dimensional printing technology, and is based on titanium alloy materials, and prints the bone fenestration positioning guide plate based on the tooth supporting type according to an optimal traction design scheme; the guide plate assembly is positioned by the tooth around the embedded tooth, is stable and does not loosen, and the positioning through hole of the guide ring part protruding from the other end tightly fits to the bone surface so as to surround the partof the simulated fenestration. Compared with the traditional stainless steel, the titanium alloy material is adopted to form the guide plate assembly, the structure compatibility is obviously superior, and soft and hard tissue inflammation reactions are not easy to occur; compared with a resin material guide plate, the titanium alloy material guide plate is lighter and thinner in volume and smaller in thickness, and is more suitable for operation in a narrow space of a posterior tooth molar area. The integrated structure is firmer and is not easy to break. The optimal position of the bone fenestration is determined according to the optimal traction and extraction path of the impending teeth.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an individualized bone fenestration guide plate for an impacted tooth based on three-dimensional printing technology. Background technique [0002] An impacted tooth refers to a tooth whose eruption period has passed, but the tooth has not fully erupted. Impacted impaction is a very common oral disease in clinical practice, and it is easy to cause a series of complications, such as recurrent pericoronitis, caries or tilting of adjacent teeth, accelerated deformity recurrence after orthodontics, food impaction, and oral odor etc. Ordinary impacted teeth can be extracted surgically, but the risk of direct extraction of impacted teeth that are closely related to important organizational structures such as the inferior alveolar neurovascular bundle, maxillary sinus cavity, and nasopalatine nerve is high, and it is easy to damage the surrounding important structures, or The postope...

Problems solved by technology

During the surgical exposure process, the blind method is often used to open the window, which has the disadvantages of inaccurate window opening position, inaccurate amount of bone removal, large trauma, and high failure rate.
