How Are Temporary Teeth Fixed?

How are temporary teeth fixed?

Although the temporary tooth may not look impressive on the outside, once the wrong fixation method is selected, it can collapse when eating a mouthful of food. Most people don't know that there is a layer of knowledge about "fixation" between temporary teeth and formal restorations. If you choose the right one, you will suffer less pain, but if you choose the wrong one, the entire project will have to be reworked.

What problems do temporary teeth solve?

After a tooth extraction, root canal treatment, or while you are waiting for a porcelain crown to be made, your doctor will make and wear a temporary tooth. The core tasks of this temporary tooth are mainly two things. The first is to ensure that there are no gaps in the teeth when you smile. The second is to prevent the adjacent teeth from falling into the missing tooth area. Follow-up data from Beijing Stomatological Hospital in 2024 shows that those who did not have Dai Lin.

Most of its materials are PMMA resin. This material is characterized by being light and strong enough, but its service life is very limited. Generally, it needs to be replaced after two to three months of wearing. It is essentially a transitional tool and is not a long-term solution, so don't expect it to last for as long as one or two years.

How to glue temporary crown on

When making a single temporary crown, the most commonly used thing is temporary adhesive. The doctor puts the temporary crown on the abutment or post and core and fixes it temporarily during the riveting and assembly process . He seals it with zinc phosphate cement or resin-based adhesive. The advantage of this method is that it can be reversed. When the formal crown is needed in the future, it can be temporarily fixed during the riveting and assembly process . It only needs to be flushed to remove it, so that the enamel surface of the abutment tooth will not be damaged.

According to data from a follow-up visit record conducted by a dental clinic in Shanghai in 2023, those crowns fixed with temporary adhesives can, on average, last at least more than 14 days without falling off.

However, if the bonding surface is not treated well, that is, if the residual saliva and blood on it are not cleaned up, loosening problems may begin to occur in as short as three or four days.

Fixed doorways for temporary fixed bridges

When two or three teeth are missing in a person's mouth, doctors often choose a temporary fixed bridge as a treatment option. The two ends of this kind of restoration will be tightly adhered to the original healthy abutment teeth, while the middle section of the bridge will be in a suspended state.

During the bonding work, the doctor will specially adjust the occlusal surface in the middle of the bridge to be slightly lower by about 0.5 mm. This is to prevent the upper and lower teeth from hitting hard, thereby protecting the natural teeth on the opposite side.

According to the statistical data of a dental center in Tianjin in 2024, the debonding rate of temporary bridges is about 8%. How to temporarily fix it during the riveting and welding assembly process , and this situation is mostly concentrated in the first week after the patient receives treatment, and the problem of frequent falling off shows that the amount of abutment preparation may not be enough, or the adhesive may be applied too thin, and eventually it will need to be replaced.

Removable dentures fixed with clasps

The so-called retention of temporary removable dentures mainly relies on clasps to lock adjacent teeth. A metal or resin clasp is designed on the healthy teeth on both sides of the missing tooth, and its tip hooks into the neck of the tooth to secure the temporary tooth. When making this set of removable dentures, the doctor will deliberately adjust the elasticity to be lighter. This can prevent the gums from being pressed out and causing ulcers due to repeated friction.

In a dental clinic in Guangzhou, the 2023 data mentioned temporary removable dentures fixed with double clasps. If patients take them off and put them on every day, the loss rate of this denture is less than 3%. The key point is that the elasticity must be matched just right. If it is too tight, it will damage the tooth body, and if it is too loose, it will not play the role of the card.

Pay attention to the details of wing panel bonding

When the clasp does not fit properly, the doctor will add thin wing plates to both sides of the temporary tooth and bond the thin wing plates to the lingual side of the adjacent teeth with adhesive. The effective area of ​​the thin wing plate is generally not less than 8 square millimeters. If the area becomes too small, the force will be dispersed, causing it to tilt up after eating.

A clinical observation published in the "Chinese Journal of Oral Medicine" in 2024 pointed out that the use of wing plate bonding in conjunction with mild bite adjustment can significantly reduce the rate of warping of temporary dentures in the posterior teeth area.

Before bonding, the cavity on the lingual side must be thoroughly polished before use. If there is a film of saliva on the surface, how is the temporary tooth fixed? There is absolutely no way to successfully bond it firmly.

What happens if you choose the wrong fixing method?

If the fixing method is incorrect, the consequences will go far beyond just the problem of falling. Because it will debond during the repeated process, and the enamel of the abutment teeth will also be thinned. If the clasp is too tight, it will cause the gums to recede, and the wing plates will fall off and loosen the adjacent teeth. In serious cases, it will interfere with the formal restoration in place, causing the entire treatment to need to be overturned.

Therefore, the process of making temporary teeth and fixing them must be done by a legally qualified practitioner. You must not randomly use materials purchased from the Internet to paste them.

You must not eat hard foods within 48 hours after the surgery. After about one to two weeks, you should come back for a review and have the doctor personally check the degree of sealing. If you find any problems, be sure to ask your doctor to correct them as early as possible.
