Parallel guiding-locating device for oral implantology

Abstract

The invention discloses a parallel guiding-locating device for oral implantology. A main guider comprises a first orientating column, a first position-fixing arm, a first orientating hole, a first position-fixing hole and a handheld arm, wherein one end of the first position-fixing arm is connected with the first orientating column, the other end of the first position-fixing arm is connected withthe handheld arm, the first orientating hole is formed in one end of the first position-fixing arm, the first orientating hole is formed in the middle of the first orientating column, and a groove isformed in the handheld arm; an auxiliary guider comprises a second position-fixing arm, one end of the second position-fixing arm is connected with a second orientating column, a second position-fixing hole is formed in the other end of the second position-fixing arm, and a second orientating hole is formed in the middle of the second orientating column; and a position-fixing screw penetrates through the first position-fixing hole and the second position-fixing so as to connect the main guider with the auxiliary guider and is a spiral screw, and a handheld wing is arranged at the upper part ofthe position-fixing screw. The parallel guiding-locating device has the beneficial effects that the device can be independently used and combined for use, is suitable for situations that one tooth islost and multiple teeth are continuously lost and can be used for advantageously and accurately implanting multiple dental implants.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a parallel guiding and positioning device for oral implantation. Background technique [0002] With the increasing improvement of oral implant technology, implant denture restoration has become the best means to treat dentition defect and loss and restore oral function under the condition of sufficient conditions (such as the quality and quantity of bone tissue in the edentulous area). The ideal implant position must meet certain requirements. Generally speaking, there should be a distance of 2-3mm between implants, and a distance of more than 1.5mm between implants and natural teeth. The implantation direction of the implant should be parallel to the long axis of the multiple implants and the long axis of the adjacent teeth. The implantation direction directly affects the restoration of the superstructure. Facilitate the restoration of dental crowns. However, due to the l...

Problems solved by technology

However, due to the limitations of the anatomical structure of the jaw or the impact of the difference in implant accuracy, it is difficult to obtain a common insertion path in clinical practice.

The application of angled abutment and personalized abutment can make up for the inclination of the implant. However, although these methods can make the upper part of the implant parallel, the part located in the alveolar bone is prone to uneven force, so that the occlusal force cannot be well aligned. The distribution of the long axis of the implant will increase the lateral force and lead to stress concentration, which may lead to clinical complications such as bone resorption and peri-implantitis

Especially for implant surgery in the posterior region, due to the limited field of view and limited operating space, most operators need to use experience to perform positioning and orientation according to the specific conditions of the operation area, and the operation is difficult. Deviations often occur in the application

At present, digital implant guides made
