Orthodontic tooth loss causes

Many consumers will want to orthodontic tooth for dental orthodontics know if there is not a phenomenon of bracket off. After many years of dental studies have shown that orthodontic specialists, orthodontic tooth loss now will be the main factors in patients, the operator factors, adhesives and other factors that affect the brackets, the following analysis on a variety of factors, one by one.

1. Patient factors: poor patients in the enamel structure after etching adhesive to form can not be embedded in all of the physical good, "honeycomb" structure affect bond strength. Poor periodontal conditions in patients, as exudate more susceptible to dental adhesive dental supplies surface exudate pollution affect the bonding effect. In addition, patients with the degree of loss is closely related with the bracket, the results show that the shedding rate bracket than adult children, women less than men.

2. Adhesive factors: dental orthodontic adhesive used in the process of adhesion is poor, adhesive curing time is too slow or too fast, adhesive deterioration or contamination may affect the bracket bonding effect.

3. Operator factors: tooth surface cleaning, etching, wet compartment is not strict, the scope is not big enough etching, adhesive mixing ratio and improper adhesive coating is uneven, place brackets incorrectly placed, also affect the viscosity take effect. The arch wire ligation into force by bit crowded teeth, excessive force is also easy to make the bracket off.

4. Bracket factors: the different types of brackets, the bond strength with the tooth surface is inconsistent. The wide wing bracket bracket spacing is small, orthodontic Down molars of implant anchorage force the Ambassador bracket easily. The shape of the bottom bracket should be consistent with the bonding of the tooth surface, and better retention type.

These are the orthodontic tooth loss because of the basic about, because more factors, in order to enhance the bonding strength of orthodontic brackets, reduce shedding, should be there before in the treatment of patients with periodontal disease to be treated, the patient closely with select agents and high-strength adhesive suitable bracket.
