Description

Crown And Bridge attachments designed by the china dental lab are generally resilient to allow free movement of the prosthesis to distribute potentially destructive forces or loads away from the abutments to supporting bone and tissue.

China Dental Lab Loyal Beauty defines three different movements in the dental design function: hinge, vertical, and rotational. The fewer abutments remain, and the weaker the abutments are, the greater the need for resiliency or free movement to direct the forces away from the abutments to the supporting bone and tissue via the base of the prosthesis.

Dental precision attachments connect removable partial dentures to fixed bridgework under a male/female locking mechanism.

Some advantages to dental precision attachments include maintainable periodontal health, less force on abutment teeth, cosmetic appearance, longevity, and stability.

The male part of dental precision attachments is often a high-strength precious alloy whereas the female part consists of a more elastic alloy.

 

China Crown And Bridge Attachment

 

Advantages of China Dental Lab Crown And Bridge Attachment include:

  1. A cosmetically enhanced cast partial denture as compared to conventional cast partial dentures that utilize cast clasps.
  2. Crown And Bridge attachment blends in with the conformity of remaining natural teeth.
  3. Functions with more even pressure on remaining natural teeth than conventional partial dentures.
  4. Less tooth reduction is required for the crown than with an intracoronal attachment. Also, the height can be made an ideal width since it does not have to accommodate an intracoronal extension.
  5. Crown And Bridge attachments are typically easier to insert and remove. These are ideal for patients with limited manual dexterity or if the prosthesis has a difficult path of insertion and removal.
  6. Intracoronary females in retaining crowns will collect food and present problems when the patient attempts to seat the intracoronal retained prosthesis. Crown And Bridge attachments do not present this problem.

 

Crown and bridge attachment Types

 

1. Bolt type precision attachment

 

Indications:

  1. Patients with unilateral and bilateral free ends missing, and the adjacent remaining abutment teeth are relatively stable;
  2. Patients with extremely high aesthetic requirements

advantage:

  1. Beautiful and comfortable, with less foreign body sensation. Good retention, effectively making up for the defect that the full mouth rubber support cannot be fully retained.
  2. The denture is easy to take and wear, suitable for too few abutment teeth and missing free ends.

 

2. Ball cap type precision attachment

 

Indications:

  1. Patients with unilateral and bilateral free ends missing, and the adjacent remaining abutment teeth are relatively stable; the residual roots are retained to restore the overdenture
  2. Patients with extremely high aesthetic requirements.

advantage:

There is no need to design a snap ring, which can effectively disperse the bite force, has a good retention force, is not easy to fall off, and the accessories can be replaced.

 

3. Grooved precision accessories

 

Indications:

Most of the teeth in the dentition are missing and the abutment does not have a common seat, or the abutment is too large.

advantage:

  1. Beautiful and comfortable, with less foreign body sensation. Good retention, effectively making up for the defect that the full mouth rubber support cannot be fully retained.
  2. Convenient to take out and put on the denture. Suitable for too few abutments and missing free ends.

 

4. Tai Chi button

 

Compared with other attachments, the Tai Chi buckle has very unique advantages. Whether it is made by technicians, operated by doctors, or used by patients, it is very simple, practical, and has a high success rate.

The advantages are as follows:

  1. It is simple to make and easy for doctors to operate. It is an ideal choice for dentists who are experienced or just beginning to make precision attachments.
  2. Easy to use, easy to take off and put on. Patients find them comfortable and easy to adapt. Simplify maintenance procedures.
  3. It has a wide range of applications, regardless of the level of occlusion, the number of abutments, unilateral, bilateral, and other indications.
  4. Robust and reliable. All foreign research and clinical practice have shown that the Tai Chi buckle attachment lasts for a long time, and the retention force is still more than 400g after four years of use.
  5. Small size and strong retention force. The mini-Tai Chi buckle is only 2.0mm high and 3.4mm wide, making it the smallest elastic attachment in the world.
  6. The airbag cushions and simulates the periodontal ligament. Within 7° of deviation from the in-position direction, the attachment can still work normally.

 

5. Sleeve crown

Features: Removable denture composed of double layers of inner and outer crowns

Advantages:

  1. Good stability
  2. The jaw force is reasonably distributed, and the chewing function is restored well
  3. Convenient removal and easy cleaning
  4. It has a protective effect on the surrounding tissues of the abutment
  5. Good long-term repair effect

Disadvantages:

  1. A large amount of tooth preparation
  2. The metal of the neck margin is exposed in the mouth
  3. High cost

Indications:

  1. Missing dentition with a small number of remaining teeth
  2. Periodontitis with dentition defect, congenital dentition defect, etc.

 

6. Locking precision accessories

The lock type precision attachment is a highly efficient structure type, which can effectively balance and offset the jaw force in the three-dimensional direction of the mouth.

Through the direct fixed connection between the restoration and the remaining tooth, the force can be transmitted to the long axis of the abutment root in the vertical direction through the male part of the attachment connected with the inner crown of the abutment.

The fixed cone-shaped abutment retaining part of the attachment body and the retaining conductor together can balance and offset the horizontal chewing force. Among them, the passive retainer, namely the locking tongue, can completely fix the restoration in its position without any side effects and will not cause abrasion to the base gums.

The locking precision attachment can be flexibly changed during processing to adapt to different teeth and gum conditions. On this premise, combined with the selection of suitable materials (such as CoCr alloy or soft materials), the requirements of modern stomatology in terms of periodontal hygiene, appearance and function can be met. Because there are no wearing parts in the structure, activation treatment is not necessary. The perfect structure makes it possible to replace various basic components under special indications.

The system is extremely simple to use and highly functional, and patients can simply and conveniently take it off. Its application range covers indications from small restorations used for interdental restoration, to unilateral and bilateral free-missing restorations, to single teeth or crowns and roots. When combined with a frictionless crown and bridge, the lock-type universal attachment can also be used as an enclosure component.

The attachment system can be widely used in the field of implantology. The attachment can transmit the physiological force, thereby avoiding excessive stress on the implant abutment, and ensuring the stable retention of the upper structure of the implant (namely, the implant denture).

The lock-type multifunctional attachment has a very wide range of applications. In recent years, it has been successfully used in particularly complex oral environments.

7. Plunger type precision attachment

Indications:

  1. Patients with unilateral and bilateral free ends missing, and the adjacent remaining abutment teeth are relatively stable;
  2. Patients with extremely high aesthetic requirements

advantage:

  1. Beautiful and comfortable, with less foreign body sensation. Good retention, effectively making up for the defect that the full mouth rubber support cannot be fully retained.
  2. Convenient to take out and put on the denture. Suitable for too few abutments and missing free ends.

 

8. Magnetic attachment

 

characteristic:

Use permanent magnets to increase retention

Advantages:

  1. Good retention, effectively making up for the defect that the full mouth rubber support cannot be fully retained
  2. Beautiful and comfortable, less foreign body sensation
  3. Effectively make up for the defect that the full mouth rubber support cannot achieve complete retention
  4. Make full use of the remaining teeth to protect the remaining roots
  5. It is convenient to take out and put on the denture. Suitable for too few abutments and missing free ends
  6. Avoid food impaction and tooth decay
