Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to assess the influence of this particular treatment method on the patients' quality of life and masticatory function.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

For this prospective randomized controlled clinical trial patients with edentulous mandibles and tissue supported (full) dentures were treated with 2 dental implants and locators in order to improve prosthesis stability.

The LOCATOR System is comprised of three parts: The LOCATOR implant attachment (LOCATOR abutment), the LOCATOR Male and the LOCATOR Denture Cap. The abutment is inserted directly into the implant using a torque wrench, while the Denture Cap is placed into the base of the overdenture for polymerization using acrylic resin. Custom retention is achieved via LOCATOR Males - small color-coded (according to retention force) plastic inserts - which can be exchanged as needed.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

A Locator with retention elements

GC Pilier Locator abutment with retention elements:

For patients in the experimental group (arm A) the connection of the full dentures to the implants will be achieved by fitting the dentures with GC Pilier Locator abutments with retention elements.

Group Type EXPERIMENTAL

A Locator with retention elements

Intervention Type DEVICE

Insertion of GC Pilier locator abutments with retention elements

B Locator without retention elements

GC Pilier Locator abutment without retention elements:

For patients with the active comparator (arm B) the full dentures will get Pilier Locator abutments without retention elements and thus no connection to the implants.
