reference example 1

[0135] The upper and lower edentulous jaw models were mounted on the mannequin (NISSIM type II, Nissim Co., Ltd.), and the upper and lower complete dentures were fabricated at the following set positions according to the general method.

[0136] (setting position of denture)

[0137] (1) Left and right incisors: Make the center of the edentulous jaw model coincide with the contact points of the left and right central incisors of the total denture (also for the upper and lower jaws).

[0138] (2) Left and right molars: Make the center of the edentulous jaw model coincide with the midpoint of the line connecting the central fossa of the left and right first molars of the total denture (also for the upper and lower jaws).

[0139] (3) Upper and lower incisors: In the incisors of the maxillary total denture, the distance from the base edge to the incisal edge of the central incisor was 22 mm (measured with a caliper).

[0140] (4) Up and down incisors: In the incisors of the mand...

Embodiment 1

[0146] Total dentures were produced for 10 subjects using upper and lower reference dentures, hard interior materials (product name: Tokuyama Lining Material III) and alignment jigs. The position of the obtained total dentures (mentioned above Parameters). Each parameter is compared with the total denture made in Reference Example 1, and ○× (good or bad) is judged according to the following criteria. In each parameter, the number of people with ○ (good) is shown in Table 1.

[0147] Alignment jigs used are figure 2 Alignment jig with the described structure. The reference denture is set in this reference denture holding part, and the hard interior material is mounted on the inner surface of the reference denture, and inserted into the oral cavity of the mannequin, and the shape of the mucosal surface is imprinted on the interior material and hardened, thereby producing Dentures.

Embodiment 2

[0149] In addition to being used as an alignment jig in figure 2 Dentures were fabricated in the same manner as in Example 1, except that the handle of the alignment jig with the described structure indicated the alignment jig in the middle of the indicator line. In addition, at the time of production, instructions are made so that the median indicator line coincides with the median of the human body model.

Abstract

Provided is a reference denture alignment jig which guides reference dentures into an oral cavity or to an articulator in which upper and lower edentulous jaw models are fixed, and aligns the reference dentures in the oral cavity or in the articulator in which upper and lower edentulous jaw models are fixed, the jig having a reference denture holding portion for holding reference dentures.

Description

technical field [0001] The invention relates to an alignment jig for reference dentures, a kit for making dentures and a method for making dentures using them. Specifically, it relates to an alignment jig for reference dentures, a denture manufacturing kit, and a denture manufacturing method using these to arrange reference dentures at appropriate positions such as inside a patient's oral cavity. Background technique [0002] In general, the shape of the oral cavity of an edentulous person, the size of the alveolar bone, the amount of absorption of the bone, the state of the mucous membrane, etc. vary from person to person. Therefore, in order to manufacture good dentures, it is necessary to manufacture dentures according to conventionally known procedures based on individual models, and a lot of time (custom-made) is required in the manufacture. [0003] Therefore, in order to easily produce a suitable and good denture, a reference denture with standardized dimensions has ...
