NCT06166316

Brief Summary

the study aims to investigate the clinical influence of different implant locations; lateral incisor, canine, and first premolar areas; supporting 2-implant retained mandibular over-dentures with locator attachment on prosthesis retention and peri-implant health.

Device: overdenture retained by locator attachments.

premolar group

ACTIVE COMPARATOR

patients having mandibular two implants in the premolar positions.

Device: overdenture retained by locator attachments.

Interventions

• Implant-retained overdenture construction procedures: 1. Primary maxillary and mandibular impressions were made, and custom trays were fabricated using auto-polymerizing acrylic resin. 2. Definitive impressions were made with non-eugenol zinc oxide paste, and the impression copings were threaded to the implants, and polyether material was injected around the copings through the opening of the tray. Auto-polymerizing acrylic resin was used to pick up the copings with the tray. Implant analogs were screwed to the copings and the impressions was poured with stone. 3. Locator abutment (Dentium, Co. Ltd., Korea) screwed in the analogs. Jaw relations were recorded, and semi-anatomical acrylic teeth eeee arranged in balanced occlusion. 4. The locator housing and retentive clips were incorporated into the fitting surface of the overdentures during denture processing.
