Effect of Block-out Spacer to Pick up Locator Attachments to Retain Overdenture: Peri-implant and Alveolar Bone Changes

Bone Loss Clinical Trial

Official title:
Effect of Using Block-out Spacer During Picking up of Locator Attachments Used for Retaining 3 Implant Mandibular Complete Overdenture: Peri-implant and Alveolar Bone Height Changes

Clinical Trial Summary

This study was conducted to radiographically evaluate peri-implant and alveolar bone height changes of locator attachments used for three implant assisted mandibular complete overdenture using two different pick up protocols.

Clinical Trial Description

This clinical trial was done to evaluate the effect of using block-out spacer during picking up of locator attachments used for retaining 3 implant mandibular complete overdenture regarding peri-implant and alveolar bone height changes. Eighteen egyptian completely edentulous male patients were chosen from the Outpatient Clinic of the Prosthodontics Department, Faculty of Dentistry, Mansoura University, Egypt. Patients received three implants one anterior in midline area and two posterior at first molar area . Patients free from any systemic diseases relating to the bone resorption, not taking any drugs that interfere with bone quality .Patients with absolute contraindication for surgical implantation, general contraindication , relative contraindication ,local contraindication for surgical implantation , allergic reactions to titanium or to local anesthesia were excluded. The main question it aims to answer is whether to use block-out spacer during picking up of locator attachments used for retaining 3 implant mandibular complete overdenture or not. - Participants were given antibiotic prophylaxis (clavulanic acid with amoxicillin 1 gm twice/day) one hour prior to surgery and continued for 6-7 days postoperative .Also, 50 mg of non-steroid anti-inflammatory tablets and analgesic (Declophenac tab) were given twice daily for one week after surgery. In addition to, Antiseptic mouth wash (0.2% chlorohexidine) was started ten minutes before surgery and continued one week after surgery twice daily. - Patients were asked for radiographic evaluation immediately (T0) and 6 (T6) then 12 months (T12) after picking up of locator attachments. Researcher compared between Block out spacer group (BOS-G) and Without block out spacer group (WBOS-G)which were randomly assigned into two equal groups to see if using block out spacer during picking up of locator attachments used for retaining 3 implant mandibular complete overdenture is more beneficial regarding peri-implant and alveolar bone height changes or not. ;
