Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of oral medicine, and particularly relates to a combined digital guide plate system for free gingival grafting. BACKGROUND

[0002] Implant restoration technology is one of the main treatment methods for patients with missing teeth, and its success not only depends on the osseointegration between the implant and the alveolar bone, but also requires the stability of the soft tissue around the implant. The sufficient thickness and width of keratinized mucosa are crucial for controlling plaque, reducing the incidence of peri-implantitis, and ensuring the long-term stability of the implant. However, studies have shown that 46%-74% of implants lack sufficient keratinized mucosa, which needs to be addressed through soft tissue augmentation surgery.

[0003] Currently, free gingival grafting (FGG) is considered the gold standard for increasing the width of keratinized mucosa, which achieves soft tissue augmentation by taking a semi-thick flap with epithelium from the maxillary palatal side, especially suitable for non-aesthetic areas. However, FGG technology still faces several problems in practical application:

[0004] (1) Difficulty in precise control of the scope of the donor tissue: Clinicians need to repeatedly trim the soft tissue during surgery to match the scope of the recipient area, which not only increases the operation time, but also may cause postoperative discomfort for patients.

[0005] (2) Risks during donor tissue acquisition: Damage to anatomical structures such as the greater palatine artery and greater palatine nerve may cause intraoperative and postoperative bleeding, numbness, and other complications.

[0006] (3) Precision problem of fixed grafts in the recipient area: It is difficult to accurately control the fixed position of the grafts, which may result in a discrepancy between the soft tissue augmentation range and the expected result.

[0007] (4) Stability problem after soft tissue transplantation: Factors such as facial muscle traction, masticatory movement, etc. may cause graft displacement and vestibular groove rebound, affecting graft vascularization and increasing the rate of contracture, thereby affecting the effect of soft tissue augmentation.

[0008] (5) Extension of the patient's edentulous time: After soft tissue transplantation surgery, patients usually need at least one month to take impressions and make upper restorations, which increases the patient's edentulous time.

[0009] In addition, although there are digital guide plates for the donor area for FGG, these guide plate designs are usually trapezoidal or rectangular, without considering the healing abutment shape, leading to difficulty in complete fitting of the graft during fixation, easy formation of cavities, and affecting vascularization. At the same time, these guide plates have single functions, without comprehensively considering the preparation range of the recipient area, postoperative graft displacement, and vestibular groove rebound, postoperative temporary repair, and other needs, limiting their effectiveness in clinical application. Therefore, the existing technology still needs further improvement and innovation to achieve the goal of soft tissue augmentation in implant restoration. SUMMARY

[0010] The purpose of the present application is to provide a combined digital guide plate system for free gingival grafting, which solves the technical problems of inconsistent soft tissue donor and recipient area range, increased surgery time, inaccurate positioning of soft tissue removal, damage to adjacent important anatomical structures, postoperative graft displacement, and increased edentulous time during soft tissue augmentation using free gingival grafting.

[0084] The preparation method of the present application is as follows:

[0085] Firstly, according to the CBCT data and digital optical scanning data (intraoral scanning or model bin scanning) of the patient before the second stage operation, the positions and shapes of the implant 7 and the healing abutment 6 are fitted and generated, the free gingival shape is generated, and the free gingival recipient site range and the donor site acquisition range are generated; as preferred, the free gingival acquisition range extends half a tooth site range mesially and distally, and the root side is located at the bottom of the vestibular groove.

[0086] According to the free gingival shape and the recipient site range, the recipient site semi-thick incision indicating guide 2, the recipient site full-thick incision indicating guide 3, the temporary restoration-soft tissue fixing clamping plate 4 and the base guide plate 1 are designed, wherein in the semi-thick incision indicating window 21, the alveolar crest horizontal incision should be located at the junction of the mucosa and the gingiva, and extend half a tooth site range mesially and distally, and the root side is located at the bottom of the vestibular groove; the contour of the guiding window 31 of the recipient site full-thick incision indicating guide 3 matches the free gingival shape, and is consistent with the shape contour of the healing abutment 6 at the corresponding position of the healing abutment 6; the working area of the guiding window 31 is mainly the corresponding position of the healing abutment, that is, the full-thick incision is only generated at the corresponding position of the healing abutment, and the full-thick flap is only prepared at the corresponding position of the healing abutment, and the remaining positions are still semi-thick flaps.

[0087] The preformed implant-supported temporary restoration 41 in the temporary restoration-soft tissue fixing clamping plate 4 is provided with occlusal screw openings 46.

[0088] According to the implant 7 penetration position, the occlusal screw openings are designed on the preformed implant-supported temporary restoration 41;

[0089] According to the wing plate shape of the free gingival design, the adaptability of the soft tissue fixation splint is improved.

[0090] The application provides a combined digital guide plate system for free gingival transplantation, which covers a recipient area half-thickness incision indicating guide plate, a recipient area full-thickness flap incision indicating guide plate, a temporary restoration-soft tissue fixation splint, and a donor area indicating guide plate, and realizes the functional integration of the whole free gingival transplantation treatment process by combining the composite structure design of "base guide plate + split accessory guide plate".

[0091] The recipient area half-thickness incision indicating guide plate can indicate the ideal incision range of the preoperative virtual design, fully considers the extension range of the coronal, apical, mesial and distal directions, and is convenient for accurate preparation of the half-thickness flap.

[0092] The recipient area full-thickness incision indicating guide plate can indicate the ideal incision range of the preoperative virtual design, fully considers the extension range of the coronal, apical, mesial and distal directions, and is convenient for accurate preparation of the half-thickness flap.

[0093] The temporary restoration-soft tissue fixation splint has two important functions: first, the preformed implant support type temporary restoration is convenient for immediate postoperative temporary restoration, and shortens the patient's edentulous period; second, the wing plate extending from the temporary crown to the root direction can cover the graft, thereby stabilizing the free gingival graft, resisting the coronal migration of the facial muscle attachment, preventing the rebound of the vestibular groove, and ensuring the efficacy of the free gingival transplantation.

[0094] The donor area indicating guide plate uses a tooth support type guide plate to outline the donor area range, is convenient to place and stable in retention; by means of digital method, the opening window range of the donor area guide plate is designed by considering the required soft tissue morphology of the recipient area, local nerve and blood vessel shape. The guide plate around the opening window has a certain thickness, and the edge has a specific direction, which is convenient for indicating the direction of the incision and avoiding damage to the anatomical structure.

[0095] The above only describes the preferred embodiments of the application, which are only illustrative and do not limit the scope of the application. Without departing from the design spirit of the application, various modifications and improvements of the technical solutions of the application made by those skilled in the art shall fall within the protection scope of the claims of the application.
