Description
Technical field
The present invention relates to a kind of preparation measuring device and using method thereof of preparing tooth body, belong to technical field of medical instruments.
Background technology
Dental esthetic reparation is the measure taking the form changing tooth and (or) periodontal tissue, makes every effort to tooth attractive in appearance and functionally obtain maximum coordination, thus makes the final effect optimization of reparation.For the patient that aesthstic district repairs, need, first through esthetic analysis design, the basis of patient's original dental tooth model to design and produce diagnosis wax pattern, i.e. target dummy.Again needing bonding porcelain hat dummy on the tooth body repaired, making the tooth body after repairing consistent with target dummy, reaching effect attractive in appearance.But there is inaesthetic projection because porcelain hat dummy has the restriction of minimum thickness and repairs tooth body, therefore, before bonding porcelain hat dummy, needing the tooth body to repairing to carry out tooth preparation, i.e. the redundance of worn tooth body; Now, tooth body to be repaired is called preparation tooth body.Tooth preparation is one of most basic operation of Prosthodontics, and in order to preserve tissue of tooth to greatest extent, few worn tissue of tooth, must grasp the spatial relation of preparation tooth volume morphing and target dummy as far as possible.There is the homogeneous space gap of certain size between the external profile of General Requirements preparation tooth and target dummy outline, be directly involved in the judgement of the worn amount of tissue of tooth and determine.Current clinical oral doctor often takes the method estimating worn amount to prepare Tooth preparation, and this kind of method error is comparatively large, and repairing effect is large to the experience dependency of clinician, especially will change in the repairing and treating of dental morphology.Often there is the situation causing tooth preparation too much (honed many tissues of tooth) or preparation not enough (needing to carry out again measuring, preparing) in existing method.Therefore, Wicresoft, fast tooth preparation need a kind of tool and method badly, the preparation amount of body of must be able to teething exactly according to simple, intuitive.
Summary of the invention
The present invention first goal of the invention is to provide a kind of preparation measuring device preparing tooth body, and this device can check that whether Tooth preparation form is desirable, measures the preparation amount of tooth body, instruct the accurate preparation of tooth body, and this device is easy to use, safe and reliable.
The present invention realizes the technological means that its first goal of the invention takes: a kind of preparation measuring device preparing tooth body, and its composition is: the silicone rubber guide plate model group for tooth preparation instruction that thickness scaling ruler and the diagnosis wax pattern die to target dummy obtain; Described silicone rubber guide plate model group comprises the tangent plane instruction model instructing the preparation of preparation tooth body tangent plane, instructs the labial surface instruction model of preparation tooth body labial surface preparation and instructs the lingual surface instruction model of preparation tooth body lingual surface preparation; The surveyingpin that described thickness scaling ruler comprises handle and is fixedly connected with handle; Surveyingpin arranges scale near the needle body side of syringe needle.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention thickness scaling ruler, intuitively, simply, accurately can measure the preparation amount of three exposed faces on preparation tooth body, as the guidance of tooth preparation by three silicone rubber guide plate models and; Than the method for existing range estimation preparation amount, it is directly perceived, simple, accurate to the measurement of the preparation amount of preparation tooth body, without the need to repeatedly observing, reduce operation link and the time of tooth preparation, decrease the sense of discomfort of patient, and good to the concordance of the tooth body repaired and target dummy, repairing effect is good.
Further, silicone rubber guide plate model group of the present invention is obtained by following methods:
A, No. three dies are carried out to the diagnosis wax pattern of target dummy, obtain holding the silicone rubber guide plate one of target preparation tooth body and adjacent 3-5 tooth body thereof, silicone rubber guide plate two and silicone rubber guide plate three respectively;
