Description
Technical Field
The invention relates to a toothless jaw oral cavity examination ruler, in particular to an examination ruler for measuring mandibular hyoglossal fossa, sublingual spongy tissue, retroglossal and dental arch width.
Background
At present, the repairing modes of the patient without the tooth jaw comprise a traditional complete denture, a biological functional denture and an implanted denture, wherein the biological functional denture has small wound, good effect and lower cost. Factors such as mandibular-hyoid posterior fossa, sublingual spongy tissue, tongue recession, arch width, etc. need to be considered when manufacturing the biofunctional denture. When the space of the lower jaw hyoid fossa is enough, the denture base extends towards the lower jaw hyoid fossa, the side edge of the tongue body is contacted with the tongue side polishing surface of the base, and compensation sealing is obtained. The sublingual spongy tissue is rich for patients, and the side edge of the false tooth tongue is contacted with the sublingual spongy tissue during functional movement, so that external closure is obtained. When the tongue retreats more, the false tooth lingual closure is easily broken to lose the adsorption force, and the tongue body retreats to occupy the false tooth space. Arch width measurements help the physician select a tray of the proper width to obtain an anatomical impression. At present, the examination of the space of the mandibular-hyoid fossa is mainly carried out by checking whether the mouth mirror can be inserted into the mandibular-hyoid fossa with 100g of force, and the force is not easy to be held by a doctor; the sublingual sponge tissue is mainly inspected by doctor observation and subjective judgment, and is rich or lack of quantitative indexes and has no objectivity; the examination of tongue recession is mainly observed by a doctor, and no tool is used for measurement; the dental arch width is mainly measured by matching the compasses with the ruler, but the two ends of the compasses are pointed, so that the mucous membrane of a patient is easily damaged. To solve the above problems, the present solution is made by this.
Disclosure of Invention
The invention aims to provide a toothless jaw oral cavity examination ruler which can simultaneously realize multiple functions including measuring a mandibular hyoid fossa posterior fossa, sublingual spongy tissue, retroglossal and dental arch width.
In order to achieve the purpose, the invention adopts the technical scheme that:
a dental-jaw-free oral examination ruler comprises a mandibular hyoglossus posterior fossa measuring end, a sublingual spongy tissue measuring end, a caliper and a handle part.
The lower jaw hyoid posterior fossa measuring end consists of a measuring head and a rod part. The measuring head is semicircular and is divided into two types according to different diameters: 25mm, 30 mm; the thickness is 2mm consistent with the thickness of the base. The rod part is made of resin and bends when the probing strength is more than 100 g; the connecting part of the rod part and the handle part is provided with threads for disassembling and replacing different measuring ends.
The sublingual spongy tissue measuring end consists of a measuring head and a metal rod. The measuring head is spherical, the diameter is 7mm, and a transverse line is arranged in the middle of the measuring head. The metal rod connects the handle and the measuring head as a whole.
The caliper is composed of a measuring claw, a pointer and a screw. The measuring jaw is cylindrical, has a diameter of 3mm and a length of 7cm, and is provided with black and white lattices, each lattice representing 1 cm. The measuring claw is fixed on the handle part through a screw and can do 60-degree hinge motion. The length of the pointer is 7mm, and the pointer is fixed at one end of the measuring jaw and rotates with the measuring jaw simultaneously.
The handle part consists of a screw rod, a caliper groove and a dial. The joint of the lower jaw hyoid posterior fossa measuring end is a screw rod. The caliper groove is the same as the measuring jaw in size. The dial is arranged on the other side of the caliper groove and is in a sector shape of 60 degrees, and the reading range is 2cm-8 cm.
By adopting the scheme, compared with the existing measuring method, the method has the following remarkable progress:
1. the invention has the function of measuring the mandibular-hyoid fossa posterior fossa and sublingual spongy tissue, thereby filling the gap of the lack of measuring tools in the past.
2. The mandible hyoplastron measuring head is divided into two diameters, and can be detached and replaced, so that a clinician can conveniently select the measuring head according to different requirements.
3. Because the rod part of the mandible hyoplastron measuring head is made of (resin), when the probing strength is more than 100g, the bending occurs, which is convenient for the clinician to control the strength.
4. The diameter of the sublingual spongy tissue measuring head is 7mm, and a transverse line is arranged in the middle of the sublingual spongy tissue measuring head, so that the sublingual spongy tissue measuring tool is provided and is not influenced by the experience of doctors.
5. Because the measuring jaw of the novel caliper is small, the upper mark is provided with scales, and the novel caliper is convenient for the measuring tongue to retreat in the entrance.
6. The measuring jaw can do hinge motion of 60 degrees, the distance range between the tail end of the measuring jaw and the sublingual spongy tissue measuring head is 2cm-8cm, the length is indicated on the dial by the pointer, the dental arch width can be conveniently measured, the mucous membrane of a patient is not easy to be damaged, and the ruler is not required to be matched for reading.
7. The invention integrates the mandibular-hyoid fossa posterior fossa, sublingual spongy tissue, tongue retreat and arch width measurement into a measurer, thereby being convenient for clinical use.
