Abstract
A completely edentulous patient presented with a chief complaint of a nonretentive mandibular implant-supported overdenture. The implants placed in areas #’s 22 and 27 exhibited excessive divergence from a frontal view. A method is described to resolve the patient’s chief complaint using prefabricated abutments and laser welding to correctly reorient LocatorTM attachments providing improved retention and patient satisfaction.

Make an impression of the intaglio surface of the overdenture with polyvinyl siloxane (PVS) putty to the Clinicians should perform a comprehensive diagnostic examination to determine the amount of available bone and use a surgical guide to place an implant at an appropriate angulation and location
Adequate base retention was accomplished by incremental laser welding of attachments to prepared prefabricated titanium abutments with the use of an appropriate mandrel in a dental surveyor
Summary
Several types of abutments are used to retain the overdentures including the LocatorTM Attachments (ZEST Anchors LLC, Escondido, CA) [4,5,6,7]. The LocatorTM attachment presents benefits to both patients and clinicians. This attachment may be used with reduced interarch space constraints and provides the advantage of internal guide planes to facilitate precise insertion. The male attachment inserts are placed at delivery and varying amounts of retentive force may be selected depending upon patient requirements. Replacement of the male attachment insert can be carried out as a brief and careful procedure when indicated [8,9]
