Fixed partial denture missing teeth

The bridge is an important part of the fixed partial denture missing tooth morphology and function. The designs of the bridge directly affect the repair effects and oral health. The bridge should have the following conditions:

(1). Able to restore form and function of the missing teeth.

(2). the role of self-cleaning, to meet the oral health requirements.

(3). Have sufficient mechanical strength, chemical stability and good Histocompatibility.

(4). Beautiful and comfortable.

In the bridge design should consider the following questions:

(1). the occlusal surface of the bridge: First occlusal morphology better, sharp clear pit and fissure ridge, is conducive to chew. Second, the size of the occlusal surface than dental instruments normal teeth small, in order to reduce the occlusal force.

(2). gingival surface of the bridge: one to keep clean; second, good-looking; the Mihashi abutment height smooth to prevent inflammation.

(3). The axial plane of the bridge: In addition to the resume form, to meet the aesthetic requirements, but also pay attention to food row overflow, to restore the correct shape and protrusion

(4). Bridge's strength: the strength of the bridge refers to the Implant plaque control and removal bending strength of the bridge. To occur when the bridge to withstand the occlusal scratch, abutments will produce the response of the flexor moment when the flexor moment stress is greater than the retention force of the retainer, make the retention of cortical from the abutment.

Planting bridge repair design

Planting bridge repair is the repair of fixed partial denture implant two or dentition defect caused by more than two missing teeth, implants, generally planted more than two implants.

China used two planting two missing tooth implant or repair the same number of more than one missing tooth implant-supported joint bracket, and some referred to Crown. More than one missing tooth, the number of implants is less than the number of missing teeth, so that manufacturing fixed implant planting bridge. Actual production and non-discriminatory, just as the implant's ability to support. Bran mark system according to different sets of classification for part of the implant restoration: standard base station, beautiful base station, small base station, the angle from base stations can also be dental instruments made from base stations. Design implant to support, a single implant can support 400 Newton; two implant repair support the 1300 Newton. Two implants can support three to four teeth, 5 to 6 implants to support a fixed denture.

The implant system design:

(1). Planting of a single system, such as a single system implantation of cylindrical implants, screw implants, leaf-shaped planting.

(2). Combination of planting, such as front teeth with a cone-shaped implant, posterior leaf-shaped implant.

(3). the surgery can use the planting of the first surgery, second surgery planted.

Implant design:

(1). Divided into a retention Cementation type and bolt retainer type.

(2). Use is divided into a temporary repair and permanent restoration.

(3). the structure can sometimes be divided into the joint crown and fixed bridges.

(4). Material into a plastic prosthesis, porcelain restorations, glass-ceramic restorations.

(5). Abutment type is divided into a beautiful type and standard.

The physiological basis of fixed partial dentures

Fixed partial denture suffered together to completely rely on the abutments to bear. Fixed partial denture has been able to withstand the force of the missing teeth, because it has compensatory missing teeth. Dentition defect cosmetic restoration treatment, according to the retention mode is divided into removable partial denture, fixed denture implant denture. Removable partial dentures supported by natural teeth and mucous membranes, through the retainer and dental instruments the base plate denture assembly in the dentition, patients can choose their own wear. Fixed partial dentures missing teeth across the gap or the end of the natural teeth for support, connected through the retention of artificial teeth, and with the cements denture luting natural teeth, the patient can not choose their own to wear. Implant denture implant implanted within the jaw, and then exposed on the mouth planting pile fitted dentures, like natural tooth morphology and function.

Carrying out a number of diseases of the mouth before the first denture treatment, such as dental caries, endodontics, root disease, periodontal disease and root. Disease to be more than a thorough treatment after tooth preparation or Implant plaque control and eliminate way implantation of artificial root, modulo, and finally complete denture making.

Principle and characteristics of the thermal optical whitening teeth

The global dental, whitening effect, persistent and sensitive issues is a big problem in the dental health whitening. British professional tooth whitening institutions internationally renowned dentist whitening experts, after several years of research and clinical, and finally the successful completion of the subject of the "hot light painless rapid tooth whitening, thermal optical whitening lights, whitening gel, whitening activation, etc. 6 international patents.

Whitening principle

Thermo-optical whitening technology use Wy10 whitening gel and activator, redox reaction, hot light white light irradiation accelerated rapid and effective access to dental internal decomposition to get rid of various stains molecules to achieve the whitening treatment.

When applied to the surface of the teeth whitening gel and activator mixed release of reactive oxygen species, heat light whitening technology contains patented activator, can be three times the whitening gel whitening effect, activation of alkaline agents to provide scientifically proven environment so that the PH value of hydrogen peroxide from below 4.5 to 10.0, the decomposition of hydrogen peroxide into free oxygen in an alkaline environment, its redox stronger and clear staining of the teeth within the molecule to enter the enamel and dentin. In addition, thermal optical whitening technology hot light white light blue light whitening active substances more efficiently into the dental instruments dentin, remove the technical excellence of coloring, thermo-optical whitening effect, making it the international market the most technologically advanced teeth whitening products .

The main ingredients: 25% hydrogen peroxide

Scope: discolored teeth due to dental fluorosis, tetracycline Stain teeth, pulp necrosis.

Advantages: UK CE certification, China SFDA certified.

25% hydrogen peroxide, effect of fast effect, the role of moderate, painless and The choice of fixed partial dentures without stimulation. High concentrations of hydrogen peroxide content, to ensure that a significant whitening effect. The use of activators, operating procedures easier for dentists to reduce operating time.

Brief Analysis of the several types of fixed partial dentures

Fixed partial dentures have the following types:

Gold deposition: very high-grade porcelain teeth completely avoid allergens, stimulate the gums, good biocompatibility, making precise, dental light, foreign body sensation, and closed high, long service life, pure and natural color.

Deposition of ceramic porcelain teeth: very high-grade porcelain teeth completely avoid allergens, stimulate the gums, good biocompatibility, making precise dental light, foreign body sensation, closed high, long service life, pure and dental instruments natural color.

Computer all-ceramic dental: very high-grade porcelain teeth, completely avoid allergens, stimulate the gums, good biocompatibility, making precise, dental light, foreign body sensation, closed high, long service life, pure and natural color.

The yellow platinum porcelain teeth: the case of precious metal porcelain dental restoration, strength, and difficult to be oxidized with little irritation of the gums, porcelain breakage, natural beauty, cheap, is an ideal choice for the general population.

Titanium porcelain teeth: FDA-approved biocompatible, corrosion resistant, wearable and affordable.

Fixed partial denture fixed dental restorations for the crowd: for adults, on the dentition, the teeth had large defects in teeth, tetracycline, and not filling root and Clinical application of modified palatal lever correction upper jaw is cross other good repair. According to oral conditions different repair methods and materials to achieve the desired natural effect.
