Dental Precision Attachment FAQ Guide

1. What is a dental precision attachment?

Dental precision attachments connect removable partial dentures to a fixed bridge in a Male/Female Locking Mechanism., it can be used to restore dental arches that do not have enough teeth for a fixed bridge. Dental precision attachments can connect a removable partial denture to a fixed bridge for better fixation.

Dental precision attachments are also available for natural roots and implants in partial and over-dentures. An attachment has two parts: a male part and a female part. When designing a removable partial denture, one part needs to be implanted in a cast or root on a crown, bridge, or splint, and the other part is implanted in a removable partial frame or acrylic. As a result, partial dentures become very aesthetic and appealing to the patient. Aesthetically, from a patient’s perspective, they will smile confidently knowing that they have normal, beautiful, natural teeth.

2. What are the benefits of a dental precision attachment compared to other dental devices of the same function?

Dental precision attachments act as stress redirectors and absorbers. Their function is to preserve soft tissue and bone and provide retention. The direct retention function of precision attachments has been shown to be more effective than retaining clasps, but the clinical situation in which they are used needs to be carefully evaluated because in all cases the patient’s standard of oral hygiene must be good, a factor that is critical for precision attachment localization.

The dental repairing process often presents dentists and patients with a dilemma between functionality and aesthetics. Removable cast partial dentures are manufactured with clasps, rests, and reciprocating components that cause significant unpleasant aesthetics as well as wear and torque on the abutments. Over-dentures can be placed directly over cast crowns or implant restoration caps. However, if patients use partial dentures or over-dentures, the benefits of retention and protection provided by precision attachments are lost. Therefore, undue pressure can be placed on the remaining roots or implants. Long-span fixed bridges, which are fabricated in one piece, are difficult to cast and install properly. Dental precision attachment that will allow fixing bridge segments can solve these problems. Different root or implant angles may not be easily corrected unless segmented connections are used.

The use of dental precision attachments can eliminate many of these problems and provide the desired aesthetics. Typical snap-in partial dentures rely on teeth and soft tissue for stability and support. Fixed dentures with properly placed and designed snaps allow occlusal forces to be direct along the axial length of the supporting teeth, minimizing torque to the abutment. Clasps do not provide an elastic mechanism to redistribute force to other areas of the mouth without causing movement or wear of the attached abutment or supporting tissue. Through these comparisons, the benefits of dental precision attachments can be concluded as providing both absolute support to your teeth and meeting your aesthetic requirements.

3. Why should you choose dental precision attachments?

Dental precision attachments are very different from other types of dentures. Dental precision attachments are perfect for those who have lost several teeth in a row, but you should still consult with your dentist before deciding to use them.

The main reason people choose dental precision attachments is that they are more supportive and longer lasting than other dentures. Even though it takes roughly the same amount of time to get either type, the dental precision attachment can ensure you use it with confidence.

The second reason is that some people are afraid of the procedure of installing dentures and surgery includes getting implants to the jawbone. The healing process can be painful and last from 6 weeks to 3 months. The process of installing dental precision attachments takes about the same time but is not as painful as implant dentures.

4. How to choose the right dental precision attachment?

There are many factors you should take into consideration while trying to get your teeth repaired. The type of locking mechanism, the material of the attachment, and the intended use should all be considered when selecting a dental precision attachment. What is more important is whether your dental condition suits the dental precision attachment. So it is recommended that you consult your dentist for detailed information.

5. What are the advantages and disadvantages of dental precision attachments?


Dental precision attachments are the best restorations where fixed restorations are contraindicated. Experience with more than 1,000 cases over the past 50 years has revealed several key advantages of this type of dental device:

  • Cosmetic Appearance
  • Maintain periodontal health
  • Long life of the abutment
  • Patient comfort
  • Problematic teeth can be repaired without affecting the case
  • Lifespan, if they are lost in the future.
  • Stability
  • Natural tooth and/or Implant Abutments can be used

Dental precision attachment can be used to compensate for future changes in the oral cavity.

There are many different kinds of dental precision attachments that will avoid unsightly clasps, make sure you make enough research and find the one that suits you best.

When used properly, dental precision attachment promotes periodontal health and longevity of the abutment, prevents resorption of the spine under partial dentures, and provides maximum patient comfort.


While there are many advantages to dental precision attachments, there are inevitably some disadvantages as well. Its main disadvantages include:

  • Teeth may require extensive preparation to provide the required space fits the inner attachment.
  • Attachments are prone to wear due to friction between metal parts. When it happens, the male part becomes loose, allowing for too much movement and threats to damage the abutment.
  • The extra coronal retainer extends from the tooth to the gum edge, so there may be gum irritation followed by the usual inflammatory sequel.
  • The extra-coronal type of attachments must occupy the space immediately adjacent to

abutment tooth, which is accurately where a replacement tooth should be placed.

6. What are the different types of dental precision attachments available on the market?

There are generally three different types of precision attachments: extra-coronal precision attachment, studs, and bars.

1)Extra-coronal precision attachment

Extra-coronal precision attachments for removable partial dentures are recommended in the following cases:

  • Fewer teeth are needed. The retention abutment is small to avoid over-contouring the coronal attachment of the abutment and/or pulp exposure.
  • External precision attachments are traditionally easier to insert and remove. These are used in patients with limited manual dexterity, or where the prosthesis has a difficult path for insertion and removal.
  • Patients don’t always wear removable prostheses. Intra-coronal female parts collect food residues while retaining abutments, and problems arise when patients attempt to place coronal retaining prostheses.
  • Extra-coronal precision attachments are usually elastic, allowing free movement of the prosthesis, transferring potentially damaging forces or loads from the abutment to the supporting bone and tissue. Three different movements are functionally defined: (1) hinge, (2) vertical, and (3) rotation.

2)Studs Attachments

Stud precision attachment for root and/or implant fixation removable over-dentures, retained in the denture in the form of a press clip. Stud attachments need to be parallel to each other for easy insertion and removal, reducing the potential for getting worn. Most brands offer solutions for implant parallelism/implant divergence. Do not allow the labial soft tissue incision to contact the base of the denture as this will alter the path of denture insertion and cause excessive wear of the parts. The stud attachment has a low profile to reduce the impact on the retention abutment, facilitate patient hygiene maintenance, allow for physiologically independent movement of the abutment, and facilitate independent service.


The advantage of bars is that the load can be distributed between the abutments. However, they place a high load on these teeth, are difficult to clean, and have complex linings. The bar is attached to the root surface by a system of posts, and a clip or sleeve is held in the denture.

The bars hold the attachments together and can increase the stability of the denture. They can be cast or milled, and a cast bar is less expensive than a milled bar. The use of UCLA abutments is required when the bar is cast. Dentists typically cast bars from chrome-cobalt alloys or various other alloys as requested by the doctor. The bars are made of titanium. There are many options available for attachments placed on the toolbar. The most popular of these are the positioner attachments or various brands of ball and socket attachments. Over-denture bars can be elastic (tissue support) or rigid (abutment support), depending on the design of the bar. The bars extending from the front to the back are rigid, while the bars in the front area are elastic. Rigid bars apply force directly to the abutment, while elastic bars apply force directly to tissue and bone. The base edge of the denture should not have a soft tissue incision on the denture base flange, as this would alter the path of denture insertion and cause excessive wear on the upper portion of the denture.

7. What steps are required to install dental precision attachments?

When it comes to teeth and dentures, every intervention you need starts with a consultation with your dentist. A quick exam can give them more information than you think, and you may need to do some x-rays so the professional will have a clear idea of what’s going on with your teeth.

  • With the initial collection of information, your dentist will likely examine the pros and cons of each option you have. This may include additional treatment and preparation. If a dental precision attachment is what you really need, the process will take some time before the precision attachment is fully fabricated and ready to use.
  • Your dentist will need to take an initial impression to begin the process. There will also be several appointments to make the necessary adjustments to the dentures. The dentist will also record your bite marks so everything fits perfectly! After a few appointments, your partial denture precision attachments are ready. This part is not difficult compared to other parts.
  • Then comes the hard part – getting used to your new dentures. Even partial dentures have different kinds of attachments, but your dentist will give you all the information you need about removing or inserting them, and all the details on how to maintain them. So just be relieved and listen to your dentist.

8. How long does it take to install a dental precision attachment?

If for any reason you need a dental precision attachment, you need to know a few things before deciding to get it. There are many reasons why people lose their teeth or get their teeth partially damaged. Some include injuries, and some are due to health issues, but one thing is common – you need dentures to restore your smile and confidence. There are many ways to do this, and dental precision attachments are one solution. Usually, it takes several weeks to install the dental precision, but it is recommended that you consult your dentist for the exact time and make sure you allow enough time.

9. What are the installation requirements for dental precision attachment?

The success of installing dental precision attachments depends on creating an ideal structure for the oral cavity. All bridge-supporting teeth are prepared with a complete shoulder preparation (flat ledges). In other words, the prepared teeth are interconnected, the gingiva (gums) and the underlying bone. Any deficiencies must be corrected surgically to create a healthy and best architectural foundation to support dentistry. Dentistry must comply with sound biomechanical principles to minimize forces on this basis. These principles include narrow occlusal (biting surface) diameter, adequate hygienic space, proper length and anatomy, firm and passive fit, and adequate occlusion (occlusal) in a correct mandibular relationship. The importance of accurate impressions and models to the overall success of a precision accessory case cannot be overemphasized. Precision accessories must be used in a precise manner to maintain a high percentage of life. Great care must be taken to ensure that each step is precise; steps cannot be skipped or the final result will suffer. The strength of the entire chain depends on the weakest link. Precision accessories have to be matched with precision – the abutment has to be stable and the frame has to fit without rocks.

10. What guidelines should I follow when installing dental precision attachments?

  • Abutments for precision attachment in removable partial dentures are selected to be splinted together.
  • The length of the dental precision attachment is more important than the width.
  • A full, narrow attachment is preferable to a short, wide attachment.
  • The length of the attachment of the implanted abutment for the correct prosthesis is determined by the height of the clinical crown of the tooth.
  • The length of the attachment of the implanted abutment for the correct prosthesis is determined by the height of the clinical crown of the tooth. If this is not feasible, precision attachments should be of equal length on both sides of similar teeth.

Robust Precision Attachments

11. How are dental precision attachments fixed?

Even without a locking mechanism, a good dental precision attachment will not dislocate during normal function. The reason why the tooth precision attachment does not consistently dislodge is that it is rooted in both directions, so the path of insertion is different from the pull of the muscles and the action of both the tongue and cavity.

While the dental precision attachment does not shift as it works, it can move slightly in a vertical direction to release forces rather than transmitting them along to the abutment. The result is a physiological stimulation of the abutments and edentulous ridges. Clinical experience has shown that this physiological stimulation can prolong the life of the abutment, even when a few teeth are required to carry the load of the entire arch. Irritation of the edentulous ridge also prevents bone resorption, which often reduces tissue support for partial dentures. The tissue under the precise fit is usually healthy and firm. Surprisingly, attachments used in this way wear very little, even after many years of function!

While the prosthesis may need to be rearranged or altered to compensate for changes in bite, it is rarely necessary to adjust or replace the male attachments part. Some genes don’t stay overnight in a glass. It is worn 24 hours a day to prevent muscle atrophy and occlusion and is only removed when it is hygienic.

12. What is the system used for implanting dental precision attachments?

The LOCATOR Implant Attachment System is designed to cover dentures or partial dentures with full or partial implant retention in the mandible or maxilla. Note that the LOCATOR attachment can also go into root canal-treated teeth or rods.


  • Minimum vertical height: The total height of the lowest LOCATOR Attachment (abutment plus male abutment) is only 3.17mm on external hexagonal implants and 2.73mm on non-hexagonal implants.
  • Positioning design: Self-positioning design allows patients to easily place overdentures without requiring precise alignment of attachment components.
  • Inner and outer retention: The unique dual retention innovation provides the LOCATOR attachment with greater retention surface area than any other attachment ever before. The combination of interior and exterior ensures the longest-lasting performance.
  • Use with non-parallel implants: Angle-correcting nylon inserts allow for easy correction of divergent implants.
  • Rotational pivoting action: The design of the Rotary LOCATOR joint allows for a resilient connection of the prosthesis without any loss of retention force. The retaining nylon male teeth are in full contact with the female sockets, while their metal denture caps perform a full range of rotational movement over the male teeth.
