Description

Technical Field

[0001] The present invention relates to the technical field of oral implant restoration, and in particular to a personalized healing base device made based on a silicone mold and a manufacturing method thereof. Background Art

[0002] After oral implant surgery, a healing abutment is often used to connect the implant to help form a stable soft tissue environment and make the subsequent restoration process more efficient. Traditional healing abutments adopt a standardized design, usually cylindrical or inverted conical, and can adapt to different clinical needs by adjusting the height and diameter. However, its fixed form cannot accurately match the patient's individual anatomical characteristics, especially in areas with high aesthetic needs (such as the anterior teeth area). The "passive healing" method often leads to insufficient gingival papillae or asymmetric gingival margins, affecting the natural beauty of the restoration and the long-term stability of soft and hard tissues.

[0003] The personalized healing abutment is tailored to the patient's tooth neck anatomy and is particularly suitable for cases with high aesthetic requirements or immediate implantation. Its precise shape optimizes soft tissue healing, quickly shapes the ideal gingival contour, maintains the height of the gingival papilla and the natural gingival margin line, while reducing the risk of micro-movement and bone resorption, and improving the function and aesthetic effect of the implant. The current production process of personalized healing abutments usually requires taking a model and then having the abutment shape made by a doctor or a processing factory. This process involves multiple steps, including data collection, design, production, and subsequent chairside adjustments to ensure that the abutment matches the patient's actual anatomical shape. This complex process is often time-consuming, resulting in overall inefficiency, which limits the popularity and promotion of personalized healing abutments. Summary of the invention

[0015] The present invention provides a personalized healing abutment device made based on a silicone mold and a method for making the same. It has the following beneficial effects: 1. The present invention seamlessly connects the process from intraoral marking of the abutment, precise matching and assembly of the mold, depth adjustment, resin property filling to efficient curing and fine post-processing. Each link is instantly optimized according to the patient's actual situation, which reduces turnover delays and shortens the production cycle.

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example: Please see attached Figure 1 The embodiment of the present invention provides a method for manufacturing a personalized healing abutment based on a silicone mold, comprising the following steps: S1. Buccal recording: Place the temporary restoration abutment into the patient's mouth, and then record the buccal data with a marker; S2, assembly: take out the temporary restoration abutment from the patient's mouth, select the corresponding tooth position part in the silicone mold according to the tooth position and the size of the gingival penetration, and then insert it into the corresponding implant substitute to assemble and obtain an assembly; S3, insertion: insert the assembly into the silicone mold according to the buccal data, and adjust the insertion depth according to the patient's intraoral conditions; S4, material injection: then injecting the light-curable fluid resin into the pores of the silicone mold, so that the light-curable fluid resin material fills the space between the assembly and the mold to obtain a combined body; S5, light curing: The assembly is cured by a light curing lamp, and after the curing is completed, the replacement body and the silicone mold are removed separately to obtain a healing abutment; S6. Trimming and disinfection: trimming and disinfecting the healing abutment to obtain a personalized healing abutment; S7. Wearing: Wear the personalized healing abutment into the patient's mouth to perform transgingival shaping of the gums.

[0024] Specifically, by installing the temporary restoration abutment into the patient's mouth and then recording the buccal data with a marker, the key information of the actual anatomical morphology around the implant in the patient's mouth is captured, the spatial reference for subsequent operations is located, and precise guidance is provided for replicating the gingival morphology of the tooth neck, ensuring that the personalized healing abutment can accurately adapt to the patient's oral environment and constructing the spatial framework foundation for abutment production.

[0025] By taking out the temporary restoration abutment from the patient's mouth, selecting the corresponding tooth position part in the silicone mold according to the tooth position and gingival penetration size, and then inserting it into the corresponding implant substitute for assembly, an assembly is obtained, thereby accurately matching and integrating the patient's individual tooth position characteristics with the mold and the substitute, building a key bridge from the actual oral condition to mold making, so that the mold can accurately reflect the morphological details of the patient's tooth neck, ensuring the morphological accuracy of subsequent resin filling and molding and the personalized foundation of the abutment, thereby improving the fit between the abutment and the patient's oral anatomical structure and laying the foundation for personalized restoration.

[0026] By inserting the assembly into the silicone mold according to the buccal data and adjusting the insertion depth according to the patient's oral conditions, the position of the healing abutment can be accurately fine-tuned and optimized in three-dimensional space. Depth adjustment ensures that the abutment achieves the best balance between alveolar bone support and soft tissue accommodation, so that the gingival part of the abutment fits the physiological structure, firmly supports the restoration while promoting healthy healing of soft tissue, forming an ideal gingival contour, thereby improving the success rate and stability of implant restorations and optimizing functional and aesthetic effects.

[0027] By injecting light-curing fluid resin into the pores of the silicone mold, the light-curing fluid resin material fills the space between the assembly and the mold to obtain a combination, so that the fluid resin can accurately replicate the morphology of the tooth neck and soft tissue under the constraint of the mold. The resin properties are adapted to the molding requirements of the mold and the abutment. During filling, it is evenly distributed according to the mold shape and accurately formed after curing. The main structure of the abutment is constructed and given good mechanical properties to meet the bearing requirements of the complex mechanical environment in the mouth, thereby improving the abutment quality and restoration durability with advanced material technology and expanding the prospects for clinical application.

[0028] The assembly is cured by a light-curing lamp, and after the curing is completed, the replacement body and the silicone mold are removed separately to obtain a healing abutment, so that the resin can be cured and formed quickly, evenly, and with controllable depth, ensuring that the resin is fully cross-linked and polymerized to shape a high-strength and stable abutment structure. At the same time, efficient demoulding improves production efficiency, maintains abutment accuracy, ensures dimensional stability and surface quality in the transition from the mold to the independent abutment, and ensures that the abutment quality is stable and reliable and meets high clinical standards.

[0029] By trimming and disinfecting the healing abutment, a personalized healing abutment can be obtained, thereby improving the surface quality and biosafety of the abutment. Trimming ensures that the patient wears comfortably and prevents soft tissue scratches and inflammation; disinfection completely kills microorganisms, eliminates infection risks, and makes the abutment meet the sterility standards for implantation in the body, creating a good oral biological environment for long-term and stable implant restoration, thereby improving patient acceptance and the success rate of implant restoration, extending the service life of the implant, and improving the restoration treatment chain.

[0030] The personalized healing abutment is inserted into the patient's mouth to perform transgingival shaping of the gums. The precise design guides the growth of gingival tissue, stabilizes the height of the gingival papilla and the gingival margin, builds an ideal soft tissue ecology around the implant, forms an aesthetically pleasing and functional transgingival contour, and creates a high-quality soft tissue foundation and aesthetic framework for the implantation of permanent restorations.

[0031] Through the gradual implementation of this method, the production cycle can be shortened, an efficient production process can be achieved, and dependence on complex equipment and multi-link medical and technical collaboration can be reduced. There is no need for patients to visit the hospital multiple times, models to be transported over long distances, and tedious turnover among multiple departments. The production process can be transformed from a traditional decentralized type to a centralized and efficient type, significantly reducing time costs and improving overall efficiency. This will strongly promote the widespread popularization and efficient application of personalized healing abutments in clinical practice, thus solving the problem that the traditional production process of personalized healing abutments is often time-consuming, resulting in overall low efficiency, thereby limiting the popularization and promotion of personalized healing abutments.

The shape and size of the gingival contour 3 match the gingival shape and size of the tooth neck. The silicone mold also includes a silicone mold 6 with a ratio of 1:1.2. The silicone mold 6 with a ratio of 1:1.2 is used to meet the gingival penetration needs of larger teeth.

[0038] Specifically, by accurately matching the gingival contour 3 with the gingival shape and size of the patient's tooth neck, and opening the substitute insertion hole 4 therein, a suitable accommodation and positioning space is provided for the temporary restoration abutment and the implant substitute, ensuring that when making a personalized healing abutment, the abutment can accurately replicate the complex anatomical structure of the gingival area of ​​the patient's tooth neck, thereby improving the fit and stability of the abutment and gingival tissue, and laying a solid foundation for the aesthetic restoration of soft tissue of implant restoration.

[0039] The overall structural strength and operational convenience of the mold are enhanced by the base bracket 5, and the silicone mold 6 with a ratio of 1:1.2 is used to cope with the diversity of patients' larger teeth' gingival penetration needs. Its flexible and adjustable characteristics enable the mold to be personalized according to the tooth size and gingival penetration conditions of different patients, expand the application range of silicone molds, and solve the problem of the limitations of conventional molds in gingival penetration adaptation for special tooth types. In clinical practice, it accurately meets the needs of making personalized healing abutments for larger teeth, ensures that the abutment can effectively shape the ideal gingival penetration contour under conditions of different tooth sizes, maintain the health and beauty of the gums and the stability of the implant function, and improve the overall personalization and clinical efficacy of implant restoration treatment.
