The method of loosening and fixing teeth Temporary periodontal splint is fixed with ligature wire, which is mainly used to tie the affected teeth together and fix them on healthy and stable adjacent teeth. First, take a section of stainless steel wire with a diameter of 0.25mm, the length of which should horizontally surround the lip and tongue surface of the teeth to be fixed, and then extend 125px. Thread the steel wire through the distal gap of the fixed tooth, then through the lingual protrusion and through the proximal gap of the tooth. The position of the ligating wire should be between the lingual carina and the adjacent contact point to prevent the steel wire from slipping off or slipping below the gingival margin, causing irritation and damage to the gingiva. Tighten the steel wire and twist it near the middle tooth gap. The number of kinks can be determined according to the width of the backlash. If the gap is small, it is ok not to kink. 8? Cross the zigzag and ligate the other tooth. The kink degree of the ligating steel wire should be appropriate, so as not to produce corrective force to change the original position of the teeth. Extend both ends of the steel wire out of the tooth gap respectively. The shape comes and goes, ending on healthy teeth. Tighten the end of the steel wire, cut off the excess steel wire, bend the broken end in the direction of the gum and put it into the interdental space to avoid loosening and displacement when chewing, and be careful not to irritate the gum and labial and buccal mucosa. Enamel adhesive or composite resin can be added when necessary to strengthen the stability of ligation. Ligation wire can also be used to temporarily fix loose teeth, that is, thin stainless steel wire with appropriate length is bent into an arch shape, which is consistent with the shape of the teeth to be fixed, and short stainless steel wire is used to bind and fix each tooth gap instead of the main wire itself.
Check the occlusal relationship after ligation to prevent biting on the steel wire. If early contact is found in clinic, occlusal adjustment should be carried out. Ligation silk should try not to hinder patients from implementing oral hygiene measures, and should strengthen oral hygiene education for patients and teach them how to control dental plaque under ligation. Generally, the adjacent surface can be cleaned with interdental brush, and the lingual tooth surface should be cleaned. It can be used for temporary fixation before trauma or periodontal surgery.
Methods of loosening and fixing teeth When making resin splint with photosensitive composite resin temporary periodontal splint, the tooth surface of fixed teeth should be thoroughly cleaned and moistureproof. After the tooth surface is corroded, it should be coated with adhesive and illuminated for 20 seconds. Select the resin material with the same color as the affected tooth, and apply a proper amount of resin to the tooth surface with a plastic knife, generally in the middle l/3 area of the crown, with a thickness of 0.5 ~ 1.0 mm, and the width of the splint should be based on the principle of not obstructing occlusion and not stimulating the gums, so as to keep the abducent gap of the gums unobstructed for the convenience of patients' self-cleaning. Curing, adjusting occlusion, eliminating early contact points, and polishing to make the surface smooth and symmetrical. It can be used for temporary fixation before trauma or periodontal surgery.
Methods of loosening and fixing teeth Temporary periodontal splint with stainless steel wire combined with composite resin After the affected teeth are tied together with fine stainless steel ligating wire, according to the above method, the adjacent surfaces of teeth lips and tongue can be covered with resin to make a composite splint made of steel wire and composite resin. Or bend 0.4mm stainless steel wire into an arch shape, which is consistent with the lingual shape of the teeth to be fixed. The tooth surface is etched and coated with adhesive. After illumination, the pre-bent steel wire was fixed on the healthy teeth on both sides with composite resin. After light curing, the surface is covered with resin and cured by light, forming a cement-like structure similar to steel bars. These two methods are based on the double fixation of steel wire and composite resin, which is stronger and more durable than using resin or steel wire alone. It can be used to fix the anterior teeth that are still loose after periodontal treatment, especially the lower anterior teeth.
With the rapid development of materials science, a kind of glass fiber material has been produced and successfully applied in oral clinic with its unique properties. Glass fiber has the advantages of light weight, thinness, high strength, good adhesion, good biocompatibility, easy operation and beautiful appearance, as shown in Figure 2. Compared with metal wire, the elastic modulus of glass fiber is close to enamel and dentin, and it has high strength and is not easy to crack. The periodontal splint made of this material has good rigidity and compactness, can effectively transmit dispersed bite force, reduce the trauma of periodontal tissue, effectively avoid the problem of repeated repair of cracked composite resin splint, and can be successfully used for more than 1 year.
Daily methods to prevent tooth loosening 1, brush your teeth gently. Brushing your teeth hard will destroy the enamel after a period of time, and after the soft tissue retreats, a gap like a bag will be produced between your teeth and gums. It's like asking for trouble and inviting infected people to live in this bag. In order to clean carefully, you should use a soft toothbrush. Brushing your teeth should be like cleaning a mirror, not a bathtub.
2. It is better to brush more than to brush well. A thorough cleaning once a day is better than a few random brushes. It takes two minutes to grind your teeth as white as pearls, but many people finish them in less than one minute. Try brushing your teeth while playing songs or TV commercials.
Don't be too attached to your toothbrush. Most dentists recommend changing the toothbrush once a month. Because it only takes a few weeks, the soft and smooth bristles will be squeezed into a ball. When the bristles are like everted steel wool, it means you should say goodbye to them.
