The probe head body 1 is a spoon (the concave curvature of the spoon is extremely small, and the picture is similar to a straight line) and the edges are rounded, and after the edges of the two sides of the probe head body 1 are bent towards the center, cambered surfaces which are attached to the outer curved surfaces of teeth are respectively formed, so that the pulled gum is protected. The central concave surface of the soup spoon of the probe head body 1 faces to the side where the head of the periodontal endoscope probe is located, which is more beneficial to supporting more space between the root surface of the tooth and the inner wall of the periodontal pocket without damaging periodontal tissues.
With continued reference to the figures, in the preferred embodiment, the widest portion of the probe head body 1 is flush with the lowermost edge of the periodontal endoscope probe head 0.
Referring to fig. 1a to 3b, when the probe head body 1 is applied to the first molar and the second molar, the widest part W of the probe head body 1 is 3.5mm, the outer diameter of the endoscope optical fiber tip 0 is 1.5mm, the width of the lower end head of the probe head body 1 is 1.5mm, and the depths of bending both side edges of the probe head body 1 toward the center are 1.5mm.
In a preferred embodiment, referring to FIGS. 1a and 1b, the length L1 of the probe head body 1 is 5mm, and the length L2 of the lower edge of the endoscope fiber tip 0 from the lower edge of the lower end head of the probe head body 1 is 2.5mm.
In another preferred embodiment, referring to fig. 2a and 2b, the length L1 of the probe head body 1 is 7mm, and the length L2 of the lower edge of the endoscope fiber tip 0 from the lower edge of the lower end head of the probe head body 1 is 4mm.
In a further preferred embodiment, referring to fig. 3a and 3b, the length L1 of the probe head body 1 is 11mm, and the length L2 of the lower edge of the endoscope fiber tip 0 from the lower edge of the lower end head of the probe head body 1 is 5mm.
Referring to fig. 4a to 6b, when the probe head body 1 is applied to a center incisor, a side incisor, a cuspid, a first premolars, and a second premolars, the widest portion W of the probe head body 1 is 2mm, the outer diameter of the endoscope optical fiber tip 0 is 1.5mm, and the width of the lower end head of the probe head body 1 is 1.5mm.
In a preferred embodiment, referring to FIGS. 4a and 4b, the length L1 of the probe head body 1 is 5mm, and the length L2 of the lower edge of the endoscope fiber tip 0 from the lower edge of the lower end head of the probe head body 1 is 2.5mm.
In another preferred embodiment, referring to fig. 5a and 5b, the length L1 of the probe head body 1 is 7mm, and the length L2 of the lower edge of the endoscope fiber tip 0 from the lower edge of the lower end head of the probe head body 1 is 4mm.
In a further preferred embodiment, referring to fig. 6a and 6b, the length L1 of the probe head body 1 is 11mm, and the length L2 of the lower edge of the endoscope fiber tip 0 from the lower edge of the lower end head of the probe head body 1 is 5mm.
Regarding the cambered surfaces which are respectively formed to be attached to the outer curved surfaces of teeth after the edges of the two sides of the probe head body 1 are bent towards the center, the simulated probe angle data (particularly shown in figure 7) of the near-middle adjacent surface, the far-middle adjacent surface, the cheek-side center and the lingual-side center of the upper jaw dentition, the lower jaw following first premolars, the second premolars, the first molar and the second molar are respectively measured by observing CT imaging data of 5 patients suffering from periodontitis, it can be seen that, when the probe head body 1 is applied to the first molar and the second molar, the average value of the included angles between the center tangents of the cambered surfaces of the outer curved surfaces of the bonded teeth, which are formed after the edges of the two sides of the probe head body 1 are bent toward the center, is 165 °. When the probe head body 1 is applied to the first premolars and the second premolars, the average value of the included angles between the central tangents of the cambered surfaces of the external curved surfaces of the bonded teeth, which are respectively formed after the edges at the two sides of the probe head body 1 are bent towards the center, is 155 degrees, and specific measurement data are shown in tables 1 and 2, and meanwhile, the probe head is shown in combination with fig. 7.
TABLE 1 simulated probe angles (°) for first molar, second molar, proximal to the middle, distal to the middle, mid-buccal, mid-lingual
TABLE 2 simulated probe angles (°) for first premolars, second premolars, proximal to distal to middle, mid-buccal, mid-lingual
Note that: in total, 5 periodontitis patients in the hospital Zhou Ke doctor were selected, and the simulated probe angles of the first premolars, the second premolars, the first molars, the second molars, the mesial-adjacent surfaces, the distal-mesial-adjacent surfaces, the mid-cheek-side midrange and the mid-lingual-side midrange of the upper and lower dentitions were measured, and the average was obtained, and found that the periodontal endoscope probe angle suitable for the first molars and the second molars was 165.7 °, and the probe angle suitable for the first premolars and the second premolars was 155.6 °.
It will be readily appreciated that in other embodiments, oval-like periodontal endoscopic probes of different sizes may be designed for different dental shape parameters, and that the clinician may actually choose the appropriate patient's instrument to operate.
Selection of probe heads of different lengths: when the teeth of clinical patients have periodontal pockets of more than or equal to 5mm and detect subgingival dental calculus, red swelling of gum and bleeding, the indication of periodontal surgery is used for controlling periodontitis, when a periodontal endoscope is not used, doctors and patients can only select flap opening surgery in the past, the defects are that the wound surface is larger, the risk of alveolar bone absorption exists, if the patients have certain serious basic diseases, the opening surgery can not be tolerated, and then the minimally invasive surgery of periodontal endoscope assisted subgingival debridement provides another minimally invasive treatment with smaller traumata, higher comfortableness and more precision for the patients. When periodontal pockets with different depths exist in teeth of a patient, periodontal endoscope probe instruments with different depths can be selected to cooperate with minimally invasive surgery treatment. The doctor can choose according to the treatment requirement.
Selection of probe heads of different widths: most adults typically have 28 to 32 permanent teeth, including 4 central incisors, 4 lateral incisors, 4 cuspids, 4 first premolars, 4 second premolars, 4 first molars, 4 second molars, and 4 third molars (see fig. 8, 9, and 10). Third grinding teeth, called blocked teeth or wisdom teeth, often require removal due to insufficient eruption or hidden danger of survival of the blocked teeth in health. In addition to the third molar, other permanent teeth are required to play very important roles such as aesthetic function of front teeth (middle incisors, side incisors, cuspids), sound producing function, cutting function, support function of rear teeth (first premolars, second premolars, first molars, second molars), chewing function, and the like, and when periodontitis exists in these teeth, it is required to be retained as much as possible. The morphology of the teeth is different due to the different positions and functions of the teeth in the dentition. Specifically, see a table 3 of statistics of measurements of the permanent teeth of a Chinese person (provenance: wang Meiqing. Oral anatomical physiology: 7 th edition: beijing: people health Press, 2012.) wherein "neck width" is the horizontal distance between the most prominent points of the mesial and distal surfaces of the margin of the tooth, which can be approximated to the lengths of the buccal and lingual sides of the tooth; "neck thickness": the horizontal distance between the labial (buccal) surface and the top of the lingual cervical margin may be approximated by the mesial and distal widths of the teeth. Through the two parameters, the data of the central incisors, the lateral incisors, the cuspids, the first premolars and the second premolars are found to have larger difference with the data of the first molars and the second molars, so the utility model designs periodontal endoscope probes with two widths, namely: 1. the probe with the widest part of the probe head body being 2mm is suitable for middle incisors, side incisors, cuspids, first premolars and second premolars; 2. the probe with the widest part of the probe head body being 3.5mm is suitable for the first molar and the second molar, and a doctor can select periodontal endoscope probes with different widths according to the treated dental position.
TABLE 3 Chinese constant dentition measurement statistics (average, unit: mm)
Note that: 1. neck width: is the horizontal distance between the most prominent points of the mesial surface and the distal surface of the cervical margin;
2. Neck thickness: is the horizontal distance between the labial (buccal) surface and the lingual top of the cervical margin.
Fig. 11 is an image of subgingival observation using the original Dental Xplorer endoscope probe. Wherein reference numeral 2 represents the root surface of the tooth root, and reference numeral 3 represents the inner wall tissue of the periodontal pocket with swelling and proliferation. Under the condition of gum swelling, after a common endoscope probe stretches into a deep periodontal pocket, the tissue on the inner wall of the swollen and proliferated periodontal pocket fills the space between the probe and the root surface of the tooth root rapidly, so that the subgingival observation space is limited.
Fig. 12 is an image of a co-located subgingival observation using the present spoon-shaped endoscopic probe. The improved endoscope probe can effectively spread the inner wall tissue of the swollen periodontal pocket, so that the space between the probe and the root surface of the tooth root is better favorable for observing the subgingival environment, and the image of the inner wall tissue of the swollen and proliferated periodontal pocket on the root surface tissue is reduced as much as possible.
The improved endoscope probe can effectively expand the inner wall tissues of the periodontal pocket after swelling, increases the observation space and the operation space, ensures that the space between the probe and the root surface of the tooth root is more favorable for the observation of subgingival environment, reduces the images of the inner wall tissues of the periodontal pocket after swelling and proliferation for the observation of the root surface tissues as much as possible, is favorable for the operation exploration and treatment, saves the time of patients and doctors, avoids the damage of the original repeated exploration to the periodontal tissues of the teeth of the patients, and is favorable for minimally invasive.
The foregoing is merely illustrative of the preferred embodiments of the present utility model and is not intended to limit the embodiments and scope of the present utility model, and it should be appreciated by those skilled in the art that equivalent substitutions and obvious variations may be made using the description and illustrations of the present utility model, and are intended to be included in the scope of the present utility model.
