Abstract
A full mouth reconstruction method and apparatus includes a denture molding structure mounted onto a patient's maxilla and mandible after being filled with an impression material, so that a static molding of the patient's gum can be performed based on the patient's occlusion. Important reference data including the vertical height of occlusion, facial midline, horizontal occlusion line, connecting line between two pupils and nose-ear horizontal line are recorded for facial and oral reconstructions while the patient is biting a first recording device, and the facial movements of the patient's chewing and speaking are recorded quickly while the patient is biting a second recording device. Records of a metal calibration are applied to obtain data of a patient' s front-and-rear, left-and-right, and up-and-down maxillary and mandibular movements through facial movements of a patient' s chewing and speaking, and these data are provided to a dental mold technician for producing the denture.
Description
METHOD AND APPARATUS OF FULL MOUTH RECONSTRUCTION
BACKGROUND OF THE INVENTION
1. Fields of the invention The present invention relates to a full mouth reconstruction method and apparatus, and more particularly, to a full mouth reconstruction method and apparatus capable of quickly recording a patient's data for one time, accurately determining the appropriateness of mounting a denture, and lowering the error of manufacturing the denture.
BACKGROUND OF THE INVENTION
1. Fields of the invention The present invention relates to a full mouth reconstruction method and apparatus, and more particularly, to a full mouth reconstruction method and apparatus capable of quickly recording a patient's data for one time, accurately determining the appropriateness of mounting a denture, and lowering the error of manufacturing the denture.
2. Descriptions of Related Art In general, replaceable artificial teeth are mounted for people whose teeth have all fallen out or required extraction due to factors including medical treatment, unexpected contraction, disease or old age.
The most common full mouth denture is in form of a movable denture and generally includes a whole set of maxillary teeth and mandibular teeth, and the size and shape of the full mouth denture are adjusted before the full mouth denture is mounted onto a patent's maxillary and madibular soft tissues for the purpose of an oral and dental rehabilitation.
As material science advances, the denture becomes increasingly stronger and more durable and comes with a natural look, and the development of denture design improves a patient's comfort and chewing efficiency.
However, the denture is generally tailored according to the shape of a patient's arch for its production and processing and thus cannot be mass produced, and the production process generally includes several times of communications between the patient and dentist during the clinical treatment, so that it takes much time before the denture can be produced, and the patient has to bear with the inconvenience caused during the period of producing the denture. After the denture is produced and mounted, the patient still needs to go through the processes of adapting the maxillary and mandibular occlusions and correcting the error (including the mold transfer error) caused by clinical and dental technologies, so that it further lengthens the time required for the production of the denture, increases the transportation cost, and causes discomfort to the patient in the period of adapting a newly installed denture. Obviously, the prior art requires further improvements.
