High Aesthetics and Retention in Partial Edentulism
Precision-attachment dentures—also known colloquially as “snap-in dentures”—are an aesthetically improved version of clasp-based dentures. Instead of using metal clasps for retention, they employ key-and-lock (precision attachment) systems concealed within crowns placed on the remaining natural teeth.
Why Are Precision Attachment Dentures Needed?
-
Maximum Aesthetics: Since the metal clasps that cross over the teeth are completely eliminated, no metal parts are visible from the outside when smiling or speaking.
-
High Stability: Thanks to the interlocking snap system, the prosthesis fits much more securely in the mouth. The sensation of movement while eating or speaking is minimized.
How does the treatment process proceed?
First, the existing natural teeth that will support the prosthesis are reduced in size and covered with porcelain or zirconium. A component of a precision attachment system (male or female) is placed on these crowns. Corresponding parts designed to fit perfectly into this system are positioned within the removable prosthesis. When the patient inserts the prosthesis, the locking mechanism engages with an audible click, securing it to the teeth.
Frequently Asked Questions
Is it difficult to use precision-attachment prostheses?
An adjustment period may be required for inserting and removing the prosthesis during the first few days, but the patient soon becomes able to insert and remove it quite comfortably.
Can it be applied to every case of partial tooth loss?
For the procedure to be feasible, it is essential to have a sufficient number of natural teeth in the mouth—of adequate strength—to support the locking system and withstand the applied loads.
Conclusion
Precision-attachment prostheses are advanced restorations ideal for patients who wish to avoid the appearance of metal clasps and seek a combination of the stability of fixed prostheses and the ease of use of removable prostheses.
