The application relates to a root canal treatment instrument, in particular to a root canal drill and grinding system with an auxiliary positioning guide plate, which is used for root canal treatment of a diseased tooth and comprises a clamping piece, a guide piece, a handset and a bracket type guide plate; the guide piece comprises a guide piece body, a central hole and guide columns; the central hole is arranged at the center of the guide piece body, and the guide columns are symmetrically arranged at the two ends of the guide piece body and take the central hole as the center; a drill needle is arranged on the handset and passes through the central hole; the clamping piece is used for clamping and fixing the guide piece on the handset; the bracket type guide plate comprises a columnar support and a retainer connected to the columnar support; the retainer is wrapped on a fixed tooth to fix the columnar support; the columnar support is symmetrically arranged with guide column insertion slots on the two sides of the diseased tooth, and guide column insertion slot cavities matched with the guide columns are arranged on the guide column insertion slots. Compared with the prior art, the application solves the problems of poor guiding accuracy, small drilling and grinding operation space, high difficulty and narrow discharge channel in the prior art.

The application relates to the technical field of dental instruments, in particular to an intelligent bite pad integrated with an opening device and a rubber dam clamp, which comprises a rubber dam clamp, the rubber dam clamp comprises two clamping arms and an elastic arc bow, the two clamping arms are connected through the arc bow, a first bite part is arranged on one side of the clamping arms close to the arc bow, a connecting shell is fixedly arranged on the top of the first bite part, a connecting port is arranged on the side, away from the first bite part, of the connecting shell, a second bite part is movably arranged on the connecting shell, an adjusting assembly for adjusting the distance between the first bite part and the second bite part is arranged in the connecting port, and bite grooves are arranged on the sides, away from each other, of the first bite part and the second bite part. During oral treatment, the rubber dam cloth is used to separate the diseased tooth from other oral structures, the diseased tooth is isolated, the patient bites the first bite part and the second bite part, the oral cavity of the patient is supported, and the comfort of the patient is improved.

This invention provides a black triangular restorative patch, comprising an elastically molded patch body. Two sides of the elastically molded patch body are bent to form a covering body. The covering body has injection holes suitable for injecting fluid resin. A traction and pressing wing extends from the outer side of the covering body away from the patch body, with the outer side of the traction and pressing wing extending outwards towards the covering body and the inner side extending inwards towards the covering body. This invention not only allows the patch to fit more tightly against the tooth but also minimizes the gap between the inner side of the traction and pressing wing and the edge of the affected tooth. This ensures a tight seal with the edge of the affected tooth after resin injection, preventing the resin from forming a protrusion and creating a smooth transition. This reduces the workload of subsequent polishing. Furthermore, the resin injection holes on the covering body avoid the problem of resin being introduced through the labial side of the patch, as is common in existing methods. Polishing only requires removing the resin corresponding to the injection hole, improving restorative efficiency.

This invention provides a scanning rod and a digital method for taking a complete impression of the root canal using the scanning rod, relating to the field of oral medicine. The method includes: scanning the patient's oral cavity using an intraoral scanner to obtain an initial digital model of the dentition; injecting a silicone rubber lightweight material into the root canal post using a syringe, and inserting the scanning rod into the root canal post while waiting for the impression material to cure; scanning the affected tooth with the scanning rod and a predetermined number of teeth on either side of the affected tooth using the intraoral scanner to obtain the scanning rod and the digital model of the dentition. The digital method for taking a complete impression of the root canal using the scanning rod provided by this invention avoids the problems of reduced accuracy and patient discomfort caused by large-area impression taking. By matching the digital model of the dentition, the scanning rod and the digital model of the dentition, and the digital impression of the post, the post data obtained is reduced, and the accuracy of the post is improved.

This invention relates to the field of dental restoration technology and discloses a method for fabricating a 3D-printed resin filling guide. In clinical practice, the affected tooth is prepared and color matched. Three-dimensional data of the patient's upper and lower jaw dentition and the prepared abutment tooth data are obtained through digital oral scanning, along with the occlusal relationship. The abutment tooth data includes the abutment tooth size, axial direction, and gingival margin morphology. The 3D-printed resin filling guide fabrication method provided by this invention, utilizing digital design and 3D printing technology, creates a resin filling guide that meets the patient's personalized needs. This fundamentally overcomes many drawbacks of existing dental resin restoration techniques, achieving precision, personalization, and minimally invasive dental resin restoration, while improving clinical operational efficiency and patient satisfaction with aesthetic treatment.

The utility model relates to the technical field of light curing lamp accessories, specifically is a kind of applied to the auxiliary member of dental curing lamp, including light curing lamp body, detachably setting sunshade on the curing lamp position outer wall of light curing lamp body, the sunshade is used to when the light curing lamp body is irradiated to patient tooth, the light of light curing lamp body is limited in the position of the tooth to be irradiated.Using the technical solutions of the present application, by setting sunshade, when using light curing lamp to irradiate the tooth position of patient, it is possible to avoid the light of light curing lamp to irradiate other positions in the mouth of patient as far as possible, in this way, directional heating of light curing lamp is realized, and the comfort of patient is improved.
