Description

Plant tooth boring positioning auxiliary device

Technical field

This utility model is a kind of positioning auxiliary device, refer to a kind of promote the make efficiency of planting tooth guide plate plant tooth boring positioning auxiliary device.

Background technology

Tooth is a kind of calcified tissue for laboratory rodent chow, when the tooth of being grown up causes damage because of oral disease or external force, then cannot regenerate, tooth may cause the atrophy of alveolar bone and gingiva after damaging and feed function is affected, for avoiding above-mentioned situation, often substitute with artificial tooth the tooth damaged, modal therapeutic modality is implant tooth now.

Implant tooth is at the dental bed place of damaging tooth, get out the hole of suitable size, artificial tooth root is inserted in this hole, after root of the tooth and dental bed grow and heal, this root of the tooth sets firmly a platform tooth, finally more artificial artificial tooth is set in the outside of this platform tooth, namely complete the course for the treatment of of planting tooth, this artificial artificial tooth can bear external force during occlusion via the support of root of the tooth and dental bed, and then recovers the masticatory function of tooth.

The step of implant tooth, first obtain sufferer for planting oral cavity, tooth position data (data) with CT Scan, again according to the dental bed model of data make patient, dental bed model carries out hole and the making of guide plate, when doctor considers bore position at agomphosis place and angle, still need and scan the position of the sufferer dentale of data with reference to sufferer oral cavity, whether thickness and dentale have defect etc., do experienced judgement correction, such as thinner for bore position dentale or when having a defect, for considering that artificial tooth root must bear the pressure of the vertical and horizontal direction after planting after tooth position normal tooth occlusion corresponding thereto, then bore position need be adjusted to and close on dentale thicker part for bore position, strength when implant tooth just can be made can to bear upper and lower dental articulation and unlikely generation deflection, therefore bore position, direction and angle whether suitable, success or not for dental implant surgical has conclusive impact.The semicircle fairlead being made as employing one baseline rod and multiple different-diameter of prior art guide plate, first sufferer is obtained for planting oral cavity, tooth position data according to CT Scan in time making, and on dental bed model agomphosis place trace mark holing, after baseline rod is located in this perforation, again dental bed model is located on horizontal survey device (Surveyor) 50 as shown in Figure 7, and in order to the direction of measuring basis bar and angle whether correct, this horizontal survey device 50 includes a discoid chassis 51, chassis 51 1 side is provided with a pillar 52, pillar 52 upper end is provided with a transverse arm 53 towards chassis 51 center position, transverse arm 53 tail end is provided with a upright arm 54 in center, chassis 51, upright arm 54 bottom is provided with a reference lever 55, a urgent knob 531 is provided with outside transverse arm 53 tail end, utilize the packing of urgent knob 531 or loosen the height that can adjust upright arm 54, upright arm 54 Basolateral is provided with a urgent knob 541, upright arm 54 bottom can be incorporated into reference to bar 55 by the packing of urgent knob 541, center, chassis 51 is provided with a discoid support seat 56, support seat 56 central upper position is provided with a universal joint 57, universal joint 57 is connected with a model clamping seats 58 above, model clamping seats 58 is in order to grip sufferer dental bed model 60, the direction of universal joint 57 whether can be adjusted by the packing of urgent knob 561, and then can adjustment model clamping seats 58 relative to the angle of reference lever 55, through reference horizontal survey device 50 reference lever 55 and the angle measurement of planting tooth position reference bar, can the direction of judgment standard bar and angle whether correct, if the direction of baseline rod or angle incorrect, need from the direction of new production dental bed model perforation and angle, need after completing to measure action above repetition, the direction of ability judgment standard bar and angle, complicatedly in program cause puzzlement, when the direction of baseline rod or angle correct, again each fairlead is sequentially socketed on baseline rod, the quantity of fairlead is arranged according to the number of drills needed for patient evaluation, the fairlead of largest diameter is the size of actual dental bed boring.

Then, use appropriate resin-coating dental bed model, baseline rod and multiple fairlead, after hardening of resin is shaped, namely form the guide plate of planting tooth, take out baseline rod and the guide plate attaching fairlead is taken off, the dental bed that this guide plate correspondence is placed on patient is sentenced the bore operation carrying out planting tooth.

The baseline rod of prior art, dental bed model need be located on horizontal survey device (Surveyor), in order to the direction of measuring basis bar and angle whether correct, make to carry out follow-up guide plate, because the angle of articulation of each tooth of sufferer is neither same, when a patient need implant many teeth, then need to repeat angle measurement repeatedly and revise drill process to be respectively charged into baseline rod again, this causes the complicated of guide plate manufacturing process and need expend the tediously long time, and for guaranteeing bore position, direction and angle correct, load the dental bed model after baseline rod to need to scan data comparison again with sufferer oral cavity again, judge whether boring direction or angle will be revised further, the reasonable time in that process need expending, therefore have and need improve further.
