Cost and complications associated with implant-supported overdentures with a resilient-attachment system: A retrospective study

Clinical and radiographic evaluations of implants as surveyed crowns for Class I removable partial dentures: A retrospective study

“…The maintenance of OD type of IARPDs have been reported frequently, resulting in the need for high maintenance fee because of frequent change of various attachments or other repairs. 47 In the present study, mechanical complications of IC-RPDs were not frequent and had the advantage that could be resolved by easy chairside manufacturing process. However, two abutment teeth showed mobility due to PDL space widening and one abutment tooth was treated endodontically due to apical periodontitis.…”

Effect of thermocycling on the retentive force of the retentive inserts in three denture attachments and their water absorption ability

“…Retention loss, which is commonly associated with material wear between the matrix and the patrix, is the most frequent complication in the implant-retained overdenture, often necessitating replacement of the retentive insert during the maintenance appointments 18) . This material wear is caused by several etiological factors 19) , including material type 20) , implant position 13,21) , the frequency of denture insertion/removals 10,11,17,22) , interimplant angulation 22) , brushing habits 23) , and cyclic loading 14) .…”

Design and Numerical-Method-Aided Optimization of a Novel Attachment System for Implant-Retained Dental Prostheses Using NiTi Shape Memory Alloys

“…The use of two dental implants in the interforaminal region and corresponding attachments for stabilizing complete dentures (Figure 1) is a frequently applied [11] and cost-effective treatment option [12], which is well documented in the literature. The use of prefabricated attachment systems such as locators (Zest Dental Solutions, Carlsbad, CA, USA), instead of utilizing individually fabricated attachments such as telescopic crowns or bars, drastically reduces the initial treatment costs in the edentulous mandible [13,14]. Several studies have shown that maintenance frequency [15] and associated costs [16] in such restorations are quite high, equaling or even exceeding initial treatment fees [14,17].…”

“…To compensate for the non-parallelism of implants and transfer inaccuracies, as well as to avoid excessive moment loading of supporting implants under dynamic masticatory loading, an attachment system has recently been described [28] incorporating a superelastic Nickel-Titanium (NiTi) element (Figures 2 and 3). The form of the NiTi element The use of prefabricated attachment systems such as locators (Zest Dental Solutions, Carlsbad, CA, USA), instead of utilizing individually fabricated attachments such as telescopic crowns or bars, drastically reduces the initial treatment costs in the edentulous mandible [13,14]. Several studies have shown that maintenance frequency [15] and associated costs [16] in such restorations are quite high, equaling or even exceeding initial treatment fees [14,17].…”

In particular, loss of retention and fractures of the prostheses in the area of the attachment constitute the two main technical complications [18,19].…”
