Loc-in Attachment for Overdentures

Download brochure in PDF

Implant overdenture is regarded as a secure and very effective treatment for patients who need full-arch rehabilitation. Though, implants ideally ought to be as parallel as it can; patients are frequently presented with alveolar bone volumes requiring implant placement in non-ideal positions. The traditional overdenture attachment systems allow a reasonable amount of angle correction.    

The fabrication of lower overdenture by two narrow platform implants is described with the dual retentive, resilient, self-locating Loc-In abutment attachment structure. This type of overdenture attachment arrangement offers the lower profile in contrast to the ball and bar attachments which is very flexible to up to 37° of divergence between two implants.  

By using Loc-In abutment as attachments, we can easily meet a purposeful, economic, and social expectation of patients easily and with fulfilment.

The natural placement of dental implantations with an overdenture parallel to each other and at right angles to the occlusal plane of the denture.

Employing this implant configuration, clinicians can easily re-establish by using commercially ready stud-style abutments, called DSI Loc-In abutments

Stud-style abutments have a long reputation for clinical success with reasonable long-term maintenance,

As compared with more complicated restorations; which is used in combination with a splinted bar restoration-making use of two to four DSI Loc-In abutments results in optimal retention, solidity, and comfort of the prosthesis with marginal bulk, maintenance, and cost.

Clinicians fancy individual overdenture abutments since they give the incredible quantity of flexibility and simplicity.

Somewhat erring on the side complex designs, clinicians prefer the simplest design that brings about fruitful clinical outcomes.

Ready to use Loc-in abutments have always been seen as being a simple and effective overdenture system because of low height, dual retention, plus a simple pick-up technique put together with easy long-term maintenance.

Moreover, for patients whose implants were placed with disproportionate angulation, stud-style abutments like Loc-In abutments, could be more challenging to insert and take off.

Different for the traditional hard nylon caps, that could become damaged and often bends inside the housing as the patient efforts to place the denture, in the long run requiring the insert being replaced prematurely, the special formulated soft silicone inserts of DSI Loc-in have much better elasticity, lower profile with a longer life-span.

Some clinicians have advocated for -angulated abutment, custom castings, or possibly a splinted bar to vary the angulation of Loc-In abutment. These methods, however, introduce increased complexity and expenses that may preclude some patients from receiving overdenture care.

Features like bony undercuts, narrow bone volume, the anterior position with the inferior alveolar nerve or maxillary sinus, proximity to vascular structures that might induce substantial bleeding, or our desire to avoid extensive bone grafting could potentially cause a clinician to angulate a dental implant, contributing to nonparallel positioning.

Loc-In abutment in angulated version can overcome some of the earlier limitations of angulation and hygiene maintenance concerns and keep many critical features that could advocate for improved physical properties.

DSI Loc-In angulated is a contemporary update of the Loc-in abutment with several exceptional designs.

The Loc-In Angulated System is available in 18° and 30° version, which permits implant angulation as much as 37° per implant, or 74° of total divergence between implants.

The dual retention characteristics of the innovative Loc-in system have already been moved totally to the external part of the abutment, removing the need for a large recess inside the abutment.

This design ultimately eases the hygiene maintenance and simplifies insertion of the abutment.

Lastly, the Loc-In abutment depends on a  titanium carbon nitride coating, which is harder and contains a better wear resistance as compared non-coloured titanium.
Benefits of Loc-In abutment

• They are the lengthy range of silicone inserts that are used to correct implant angulation as much as 7°

• They are different retention option, comprising normal retention, heavy, extra-light and even zero retention.

• Works with the most popular implant systems - Internal Hex and Conical Connection platforms

• The abridged height in this attachment is undoubtedly beneficial for cases with inadequate interocclusal space or when retrofitting a prevailing old denture.    

• The rounded edges of the abutment help to guide the male in the denture into place (self-aligning lock feature).

• Loc-in straight attachment will probably accommodate divergent implants up to 7 degrees, while angulated version provides you with up to 74-degree off-axis options.

• Easy long-term maintenance.
