Partial Braces: bracketing front teeth partially
What are partial braces
Partial braces are not placed on all teeth, but on few teeth or only on one jaw. Partial braces are used when malocclusion and curvature of the teeth are localized. Another application is dental prosthetics, when you need to create free space for the installation of a prosthesis.

Partial braces on one jaw or part of the dentition is not always rational, but it is still possible and effective in some cases. Partial braces will be the best option when you need to correct individual crooked teeth in the absence of malocclusion and jaw asymmetry, or as a re-treatment of occlusion.
As a rule, partial braces are not worn for so long - in some cases, only six months. Although it all depends on the unevenness of the jaw and the work that needs to be done with the braces.
Such minor deviations, allowing partial braces to be worn, occur in a total of 5% of patients. Therefore, in any case, you need to contact a specialist to determine whether you need to install partial braces, or you still have to install full ones.
As a rule, you still need a full complex effect of high-quality braces on the upper and lower jaws.
Indications for partial installation of braces
Incorrect position of one or two teeth.
Slight crowding of teeth, when the lack of space does not exceed 3 mm.
The spaces between the front teeth, provided that there are no pathologies of the lateral teeth closing.
The need to correct the position of the teeth before prosthetics.
Cases when it is necessary to keep the upper lateral teeth from excessive sagging in the absence of antagonist teeth in the lower jaw.
Before deciding on the placement of braces, you must:
X-ray diagnostic examination of the jaw, photo protocol,
check the condition of the bone tissue,
assess the condition of the roots of the teeth.
Only after a complete diagnosis, the doctor can draw up a treatment plan and decide whether it is possible to do with the installation of a bracket system on only one jaw or part of it.
Partial braces are half, or even less, of the standard brace design. To correct the defect, the braces are attached to the surface of the teeth of only one row (and not to all) and are connected with only one arch. Push springs can be attached to the orthoductus to help free up space so that the teeth can be correctly positioned.
Partial braces are possible on any of the jaws. It is also necessary to visit your specialist once a month to monitor the therapy process. Adult patients usually wear fragmented braces for about 10 months. In children, this process takes up to 2 years and the correction is completed when all permanent molars are erupted.
At the end of the treatment, the orthodontist also removes the partial braces. The enamel is ground only on the teeth under the braces. Remineralization after correction for partial braces is not necessary, but specialists always recommend it as a good preventive procedure.
Partial Braces Case Examples
Partial braces for slight crowding in front teeth of the lower row
The attachment of braces only to the mandibular teeth is possible provided that the teeth of the upper jaw are even and the antagonists are acceptable in the lateral sections. Teeth grow unevenly in a row, usually due to a lack of space. Therefore, the key criterion for correcting a defect is the size of the space that the teeth lack.
The alignment of the lower front teeth will only be possible, if they are a lack of space of no more than 3 millimeters. Space for these teeth is created by grinding the contacting surfaces (from each to 0.25 mm, in total 1-2 mm), which is harmless to the health of the lower teeth and does not harm the normal closure with the upper front teeth.
Partial braces for slight crowding in the front teeth of the upper jaw without deep bite.
If upper front teeth are crowdd and the require a space of 2-3mm for proper alighment, then problem can be treated with partial braces. There is a opportunity to correct the defect from above without removing, without touching the lower teeth. Space is freed up by separating the front units if their size and shape allow grinding. The total width of the teeth decreases, and they fit freely in the row.
Partial braces for the grooves between the frontal teeth of one of the Jaw
In this case, the lateral antagonists close correctly, and the anterior ones form a gap in the anteroposterior plane. This problem is not common. It arises from the difference in forces between the pressure of the tongue and the opposition of the lips. In this case, filling restoration of units with incorrect dimensions may be required. To avoid relapse, retainers must be worn for a long time after closing the gaps.
To close the spaces after tooth extraction or orthodontic preparation for the placement of microimplants.
Sometimes it is possible to move the chewing teeth forward so as not to implant in place of previously pulled out posterior units. Such a correction takes a long time and requires considerable orthodontic experience. The treatment takes from 8-12 months to 4 years, depending on the number of teeth moved and the time that has passed since the vacancy appeared.
There are situations when, after tooth extraction, the space in the lateral regions is partially closed due to the movement of the "neighbors", but there is not enough space for the introduction of an artificial root. Then single-jaw braces need to work on changing the inclination of the teeth in the direction opposite to the free space.
Partial braces for excessively erupted posterior teeth that do not have antagonists
If one or several units have no antagonists for a long time, then she (they) move until contact is reached, thereby reducing the space for dentures in the place of the lost teeth. The problem is solved by moving the advanced units to their original position. For teeth, this is an extremely difficult migration. The introduction of microimplants requires the control of all the forces that act on the teeth.
Limitation of Paetial Braces
Some orthodontic problems can be solved with the installation of braces on only on one jaw dentition. However, it should be understood that single-jaw treatment is often more difficult than on both jaws, due to the need to control processes that are less significant in two-jaw treatment.
Full braces moves the teeth in 3 planes, ensuring the evenness of the rows and the correct closure. With partial brace therapy, there is a risk of serious negative effects, and it may be necessary to connect the units of the opposite jaw to the system.
Most often, the installation is carried out not partially, but on both jaws and on all teeth. The reason is that braces affect the alignment of the teeth and the bite. And when the bite is incorrect, it affects not only aesthetics, but also the correct functioning of the entire digestive system, becoming the cause of various diseases of the body.
The decision to partially install braces for treatment is made on an individual basis, depending on the specific situation. And even after insertion, another jaw that has not been installed can be controlled, for example, with removable retainers worn overnight.
Why are these partial braces so good:
The main advantage is that the discomfort from wearing the structure during treatment is minimized. Less stress, less discomfort. Also, a partial orthodontic system is less visible, especially if it is ceramic or sapphire rather than metal. It is possible to install a lingual partial system. Placement takes place on the back of the teeth, because the braces are almost invisible during a conversation or when smiling.
In contrast to full-fledged braces, in some cases, a partial system can be installed even in children from eight years old, when not all milk teeth have been replaced by permanent ones.
If it is possible to install a partial bracket system, mainly on 6 teeth, then the price of the service will be much lower.
Partial installation of braces is possible in the following situations:
The curvature of the teeth is negligible. An indispensable condition is the correct closing of the posterior teeth.
Lack of space in the jaw (up to 1-3 mm).
Full matching of molars / canines, no serious malocclusion.
In other situations, it will be contraindicated. The conditions under which partial installation of braces is possible exist, at best, in 5% of patients.
In most cases, it is recommended to install a full-fledged bracket system for two jaws. The reason is that the partial design is more suitable for the treatment of curvature of teeth than for malocclusion. But it is the latter that directly affects the patient's health.
How are partial braces placed?
The procedure for installing a partial bracket system is, in principle, no different from installing a full bracket and includes:
Initial examination, during which the orthodontist will determine the further stages of treatment, cost and necessary procedures;
Creation of a 3D panoramic dental image;
Taking an impression;
Selection of braces taking into account the estimated cost and the client's wishes (lingual braces, ceramic braces, metal braces, etc.).
Qualitative fixation of the partial system is carried out
After that, you periodically need to come to the clinic to activate partial braces. Usually, an examination takes place every 4-5 weeks, the orthodontist checks the achieved result of the treatment and, if necessary, makes adjustments.
The total duration of treatment is individual, on average it lasts up to 10 months in adults and up to 2 years in children. All this time, it is important to adhere to the recommendations of the orthodontist, to properly care for partial braces, to follow the schedule of visiting a doctor.
Partial braces are attached in the same way as ordinary braces - these are clasps that hold the correction wire. Materials for them are also used similar to full bracket systems - metal, ceramics, plastic (the least popular, albeit cheap material), sapphire.
The good news is that the cost of partial braces is much cheaper than the cost of full ones.
Types of Partial Bracket System
Installation of braces for 2 or more teeth is required for minor correction of bite and dentition. As the best options, modern orthodontics offers the following types of partial systems:
metal braces. The most popular option used in most cases. Metal structures are highly efficient and affordable. lingual braces system. They are invisible, but at the same time they successfully cope with their task of correcting the incorrect position of the teeth.
ceramic / sapphire braces. These corrective constructions are very gentle in relation to the teeth and practically do not damage the enamel. From the point of view of aesthetics, this type of bracket systems is more attractive, which is especially important for adolescents, as well as adults, whose working conditions imply constant communication with other people.
The 2 by 4 bracket system is one of the most popular partial restorations. It is used for early treatment of bite in children or in situations of slight curvature of teeth in adults. The system got its name because of the principle of its fixation (attached to two canines and four molars).
Quite often, after treatment with a partial bracket system on one jaw, the doctor recommends installing the structure on the other. In orthodontic treatment, such situations are not uncommon, they are focused on the complete restoration of the correct position of the patient's teeth.
Frequently Asked Questions
Can you get braces on just a few teeth?
Partial braces on a few teeth or part of the teeth setup is not always rational, but it is still possible and effective in some cases. Braces on few teeth will be the best option when you need to correct individual crooked teeth in the absence of malocclusion and jaw asymmetry. Possibility of braces on few teeth depends on severity of the case, and whether the problem is localised or involves teeth in multiple locations.
Do partial braces hurt?
The main advantage is that the discomfort from wearing the structure during treatment is minimized. Less stress, less discomfort. Partial braces mostly consist of brackets on few teeth and lack complicated and traumatic components of conventional braces
How long does it take to put on partial braces?
The total duration of treatment with partial braces is individual, on average it lasts up to 10 months in adults and up to 2 years in children. All this time, it is important to adhere to the recommendations of the orthodontist, to properly care for partial braces, to follow the schedule of visiting a doctor.
