Abstract

The invention discloses a combined guide plate for removable denture abutment tooth preparation and implant implantation and a manufacturing method thereof, and the manufacturing method comprises the following steps: preparing a dentition and an alveolar ridge model, and then carrying out digital scanning on the dentition, the alveolar ridge model and a dentition mouth to obtain a digital model; matching the digital model with a CBCT three-dimensional reconstruction alveolar bone model shot by a patient to obtain a removable denture base three-dimensional model; carrying out removable denture in-position path analysis and determination on the removable denture base three-dimensional model, and then manufacturing an abutment hole, a removable denture abutment preparation guide rod and an implant implantation guide ring to obtain a combined guide plate three-dimensional model; and generating the three-dimensional model of the combined guide plate through a computer, and carrying out 3D resin printing to obtain the combined guide plate for removable denture abutment tooth preparation and implant implantation. The combined guide plate prepared by the invention has the advantages of reducing abrasion among implant components, smoothly and passively positioning and taking out RPD, slowing down absorption of edge alveolar ridges and ensuring the service life of the implant in the use process.

Description

technical field

[0001] The invention relates to the technical field of dentures, in particular to a combined guide plate for removable denture abutment tooth preparation and implant implantation and a manufacturing method thereof. Background technique

[0002] The loss of the free end of the tooth is one of the common types of dentition defects in clinical medicine. Generally speaking, the anterior teeth remain and the posterior teeth are missing. Due to the particularity of the missing teeth, removable partial dentures (RPD) are traditionally used Restoration, due to the lack of natural teeth or bony support structures at the end of the tooth to provide support or retention for the removable partial denture during the restoration process, the alveolar ridge and mucous membrane in the edentulous area are stressed, the toothache is obvious, and the alveolar ridge absorbs quickly.

[0003] After the traditional removable partial denture is repaired, the rest of the removable p...
