Abstract
The invention discloses a super hard gypsum alveolus bone model for preparing loose tooth. 1. Sterilizing the off body tooth and drying. 2. Preparing a round hole in off body tooth apex 3. Preparing serial tooth root with stainless steel wire. 4. placing the off body tooth upside down in die. 5. Using wax sheet to coat the tooth root. 6. Mixing the gypsum with water into paste. 7. Filling gypsum paste into alveolus bone silicon rubber die. 8. Hardening at room temperature, the process is simple.
Description
Technical field
The present invention relates to design of dentistry teaching mode and manufacture field, more specifically relate to the method for preparing agomphiasis on a kind of super hard gypsum alveolar bone model.
Background technology
Tooth mobility is an important pathological characters of periodontitis, is the inevitable outcome that periodontitis develops into certain phase.Thereby, there is not the model of agomphiasis, can not be called real periodontosis model." pine and do not take off " is the essential characteristic of periodontosis agomphiasis.Existing agomphiasis model, be simply acrylic resin tooth or stripped eye cutting must be gone in the tooth socket of alveolar bone model, agomphiasis is easy to come off out from tooth socket, does not reach the technical requirement of " pine and do not take off ", teaching can only be done in actual applications, operation training can not be carried out.The method of not seeing loose tooth on a kind of super hard gypsum alveolar bone model by retrieval is disclosed or uses.
Summary of the invention
The objective of the invention is to be to provide a kind of on super hard gypsum people alveolar bone model the method for loose tooth, should method is simple, not only can be used for teaching, can carry out also that loose tooth is fixing to wait the multi-mode operation training.
To achieve these goals, the present invention takes following measure: the stripped tooth that will collect soaked 42-56 hour in 10% formalin solution, dried 24-48 hour.At the circular hole of nature apex radicis dentis 1/3 district preparation one middle-distant direction that exsomatizes, diameter 1.5-2.5mm, then with the stainless steel wire of diameter 1.5-2.0mm will draw up be equipped with agomphiasis the root of the tooth string together, form fixing device, the perfusion super hard gypsum before, with wax disk(-sc) with root of the tooth bag quilt, the about 0.5-1mm of thickness.The super hard gypsum powder is pressed gouache ratio: 7ml: 30g slowly adds the super hard gypsum powder in rubber cup and is modulated into paste in the tap water; The super hard gypsum paste is poured in the alveolar bone silicone rubber impression, and the limit is with the vibration of paste limit, to remove the bubble in the paste, in order to avoid influence mold surface form and quality; Room temperature (20-25 ℃) was solidified 20-30 minute, and general set time in summer is short, and set time in winter is long; When treating that the model surface temperature is reduced to room temperature (20-25 ℃) plaster cast is pulled out; Room temperature (20-25 ℃) aeration-drying place is down preserved.
The present invention compared with prior art has following advantage: simulate effect is good, can reflect the characteristics of periodontosis agomphiasis " pine and do not take off " truly; Technology is simple, does not need special instrument and equipment; The starting material wide material sources; Fixing device is firm, can carry out scraping under the gum control, operation training such as root planing, and can use repeatedly; But the model long preservation is indeformable.
Embodiment
The method of loose tooth the steps include: on the super hard gypsum alveolar bone model
(1) the stripped tooth that will collect soaked 46 or 48 or 50 or 52 or 54 hours in 10% formalin solution, dried 24-48 hour;
(2) prepare the circular hole of a middle-distant direction in isolated tooth root point 1/3 district, diameter 2mm;
(3) the root of the tooth polyphone that will draw up and be equipped with agomphiasis with the stainless steel wire of diameter 1mm;
(4) stripped tooth is inverted in the die;
(5) with wax disk(-sc) with root of the tooth bag quilt, the about 1mm of thickness;
(6) the super hard gypsum powder is pressed gouache ratio: 7ml: 30g slowly adds the super hard gypsum powder in rubber cup and is modulated into paste in the tap water;
(7) the super hard gypsum paste is poured in the alveolar bone silicone rubber impression, the limit is with the vibration of paste limit, to remove the bubble in the paste, in order to avoid influence mold surface form and quality;
(8) room temperature (25 ℃) was solidified 30 minutes, and general set time in summer is short, and set time in winter is long;
When (9) treating that the model surface temperature is reduced to room temperature (25 ℃) plaster cast is pulled out;
(10) room temperature (25 ℃) aeration-drying place preservation down.
