A post-skin flap surgery vestibular sulcus shaping press plate

Abstract

This invention discloses a vestibular sulcus shaping plate for use after flap surgery, comprising a plate body. The plate body has a pre-hole positioning structure, a tooth positioning structure, a vestibular sulcus shaping structure, and a fixation structure. The pre-hole positioning structure has at least one pre-hole provided on the vestibular sulcus shaping structure to provide a standardized access for bone screws or fixation instruments. The vestibular sulcus shaping structure matches the flap implantation area and is used to shape the vestibular sulcus. The tooth positioning structure has at least one tooth and is connected to the vestibular sulcus shaping structure through the fixation structure. The tooth positioning structure matches the shape of the teeth. This invention uses a tooth positioning structure that matches the teeth in the patient's oral cavity to limit and fix the plate body, and then uses the vestibular sulcus shaping structure to form support in the patient's flap implantation area, thereby shaping the vestibular sulcus and minimizing the possibility of the vestibular sulcus becoming shallow, which facilitates subsequent prosthetic restoration.

[0002] In recent years, the number of patients undergoing oral tumor resection flap repair has been increasing. After flap repair, the patient's vestibule often becomes shallow due to tissue filling effect or scar shrinkage, which leads to difficulties in subsequent denture restoration. Therefore, there is an urgent need in this field for an effective vestibule shaping plate to solve this problem. Utility Model Content

[0003] To address the aforementioned technical problems, this invention provides a vestibular sulcus shaping plate for post-flap surgery, which can assist in shaping the vestibular sulcus and enable patients undergoing oral tumor flap repair to achieve a good vestibular sulcus shape.

[0004] To achieve the above-mentioned technical objectives and effects, this application provides the following technical solution: A vestibular sulcus shaping plate for post-flap surgery includes a plate body. The plate body has a pre-hole positioning structure, a tooth positioning structure, a vestibular sulcus shaping structure, and a fixation structure. The pre-hole positioning structure is at least one pre-hole provided on the vestibular sulcus shaping structure to provide a standardized access for bone screws or fixation instruments. The vestibular sulcus shaping structure matches the flap implantation area and is used to shape the vestibular sulcus. The tooth positioning structure has at least one tooth that is connected to the vestibular sulcus shaping structure through the fixation structure. The tooth positioning structure matches the shape of the teeth.

[0005] Preferably, the pre-hole positioning structure is provided in at least two locations, one on the labial side and the other on the lingual side of the alveolar bone.

[0006] Preferably, the pre-hole positioning structure is provided in at least two locations, which are respectively located on the buccal side and palatal side of the alveolar bone.

[0007] Preferably, the tooth positioning structure is provided in two parts and is disposed on both sides of the tooth positioning structure, including a first positioning structure and a second positioning structure, wherein both the first positioning structure and the second positioning structure have at least one positioning groove that is adapted to the remaining teeth in the oral cavity.

[0008] Preferably, the hole positioning structure is a through-hole.

[0009] Preferably, the pressure plate body is a plate structure made of metal or resin.

[0010] The vestibular sulcus shaping plate provided by this utility model has the following advantages: This invention relates to a vestibular sulcus shaping plate used after flap surgery. The plate body is fixed and positioned by a tooth positioning structure that matches the teeth in the patient's mouth. The vestibular sulcus shaping structure provides support in the flap implantation area, thereby shaping the vestibular sulcus and minimizing the possibility of the vestibular sulcus becoming shallow, which facilitates subsequent denture restoration.

Detailed Implementation

[0012] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] Reference Figure 1 and Figure 2 A vestibular sulcus shaping plate for use after flap surgery includes a plate body 1, which is a plate structure made of metal or resin. The plate body 1 has an integrally formed hole positioning structure 11, a tooth positioning structure 12, a vestibular sulcus shaping structure 13 and a fixation structure 14. Specifically, the pre-hole positioning structure 11 is at least one pre-hole opened on the vestibular sulcus shaping structure 13, providing a standardized approach for bone screws or fixation instruments to achieve precise positioning and avoid tissue damage caused by intraoperative displacement. The pre-hole positioning structure 11 is connected to the vestibular sulcus shaping structure 13, which matches the flap implantation area to shape the vestibular sulcus. At the same time, when the vestibular sulcus shaping structure 13 conforms to the shape of the vestibular sulcus, the pre-hole positioning structure 11 can help restore the groove depth and prevent the vestibular sulcus from becoming shallow due to misalignment after flap repair. The tooth positioning structure 12 is provided with at least one tooth and is connected to the pre-hole positioning structure 11 and the vestibular sulcus shaping structure 13 through the fixation structure 14. The tooth positioning structure 12 matches the shape of the teeth.

[0014] Furthermore, the pre-hole positioning structure 11 is a through-hole round hole. At least two pre-hole positioning structures 11 are provided and are respectively located on the labial and lingual sides of the alveolar bone or the buccal and palatal sides of the alveolar bone. This provides high ease of operation, clear field of vision, and strong mechanical stability, while avoiding damage to important structures, such as the mandibular nerve canal, and reducing the risk of nerve damage.

[0015] Reference Figure 1 and Figure 2 Preferably, two tooth positioning structures 12 are installed and are respectively located on both sides of the tooth positioning structure 12, including a first positioning structure 121 and a second positioning structure 122. Both the first positioning structure 121 and the second positioning structure 122 have at least one positioning groove that is adapted to the remaining teeth in the oral cavity. The first positioning structure 121 and the second positioning structure 122 are designed according to the three-dimensional model of the patient before the operation and match the shape of the teeth. While ensuring the installation and adaptation effect of the pressure plate body 1, the possibility of the pressure plate body 1 moving is avoided, thus ensuring the support and shaping effect of the vestibule shaping structure 13.
