Description
Technical Field
The utility model relates to the technical field of invisible orthodontic appliances, in particular to a removable and wearable covering type invisible plane guide plate and an invisible orthodontic device.
Background
In orthodontic treatment, the opening of the occlusion is mainly achieved by anterior tooth depression and/or posterior tooth elongation. In the traditional fixed correction technology, for patients with a steep Spee curve and deep covered anterior teeth, when the elastic force of a straight arch wire is not enough to realize occlusion opening, rocking chair arches, step curves, auxiliary arches and the like are often selected to be arranged on the arch wire for occlusion opening.
The bracket-free transparent orthodontic technology has been widely accepted by doctors and patients as an orthodontic technology which is beautiful, sanitary and efficient. In the invisible orthodontic technology, by using the rocking chair arch concept of the traditional orthodontic technology, the dentition target position is usually designed into an inverse Spee curve, and the lower-pressure incisors are designed to be overcorrected at the lower-pressure incisors. For patients with higher difficulty in occlusion opening, design of a precise occlusal plate (Bite cams) on the lingual side is considered to realize incisor depression. The Bite cams are cylindrical hollow bubble type bulges added on the upper jaw 3-3 (or 3 alone or 1 and 2 alone) palatal side of the transparent appliance, and when a patient normally bites, the lower front teeth are firstly contacted with the Bite cams, so that the occlusion of the rear teeth can be opened while the contact of the front teeth is kept, unnecessary biting force of the rear teeth area is eliminated, and the compression of the front teeth and the extension of the rear teeth are assisted.
Although the invisible correction technology has become mature, the effect of the bite opening is not satisfactory in most cases. The effectiveness of transparent appliances at low incisor pressure is only about 50%. Therefore, for deep occlusal cases, the effect of opening the occlusion by simply relying on a transparent appliance is not ideal. In most cases, the final target position can be realized only by continuously restarting and continuously increasing the reduction of incisor teeth, so that the treatment time is prolonged, the treatment cost of a patient is greatly increased, and the burden of a doctor is increased. The reason is analyzed as follows:
1. although the effect is better to the interlock is opened to traditional fixed the correcting using movable plane baffle, nevertheless because the stealthy skill of correcting in nothing support groove adopts dentition full parcel formula to correct the ware, traditional plane baffle can't be compatible to be worn.
In addition, the conventional fixed planar guide directly presses the lower incisors, force control is limited, and side effects of absorption of the lower incisor roots may be increased.
2. Based on the concept of 'rocking chair arch' in the traditional correction, means such as designing an inverse Spee curve for a target position of a tooth socket, designing correction for tooth movement amount and the like all depend on the control of the tooth socket on tooth movement. However, the effective rate of the transparent appliance at low incisor pressure is only about 50%, and posterior tooth elongation is also one of the most difficult tooth movement methods for the transparent appliance, and therefore the difficulty of opening the occlusion is high.
3. The Bite rates are more limited in use: due to its small size, it is only suitable for patients covering normal or I-depth coverage. The conventional BiteRamps are only suitable for covering patients with the thickness less than 3mm, the widened BiteRamps can only achieve the occlusion range of 4-5mm, and if the coverage of the patients exceeds the sagittal length of the BiteRamps, the lower front teeth not only are difficult to Bite into the BiteRamps to achieve occlusion opening, but also are easy to cause the lower jaw to be forced to retreat. Meanwhile, because the Bite arms are directly arranged on the upper anterior palate side, the wrapping of the upper anterior facing braces is influenced on one hand, and on the other hand, the pressure in the vertical direction is applied on the upper anterior palate side, so that the Bite arms are unfavorable for anterior teeth with poor torque, and side effects such as anterior tooth torque loss, occlusion trauma and the like are easily generated.
