Immediate Versus Delayed Loading for Implants Retaining Mandibular Complete Overdenture

Study Overview
=================
Brief Summary
-----------------
The aim of this study will be to compare the amount of marginal bone height changes between immediate and delayed loading for immediately inserted implants used as abutments of mandibular overdenture.

Official Title
-----------------
Immediate Versus Delayed Loading for Immediately Inserted Implants Retaining Mandibular Complete Overdenture

Conditions
-----------------
Bone Loss, Dental Implant

Intervention / Treatment
-----------------
* Other: Immediate loading of the implants
* Other: Delayed loading of the implant


Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Patient having two standing mandibular canines with compromised prognosis (which indicted for extraction, without any preapical lesions nor acute infection) and have an adequate labial bone thickness. Patient having opposing completely edenteolous maxilla. Patients having normal maxilla-mandibular relationship and sufficient inter arch distance was insured by through tentative jaw relation record. Patients with good oral hygiene. Enough bone volume for implants in the interforaminal region (adequate bone quality and quantity) Exclusion Criteria: Mental disorder patients who are not capable of making a decision or narcotic drug addicts. Patients with Tempro-Mandibular Joint disorders Patients undergoing radiotherapy or chemotherapy Patients with systemic diseases affecting bone metabolism Uncooperative patients who have no understanding of the need of a regular follow-up. Patient with pathological defects in the areas of implant insertion. Vulnerable group as prisoners, mentally retarded patients.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in bone loss | Every 3 months all patients were recalled for assessment of marginal bone loss. The assessment was done using digital periapical radiograph Ezsensor (Vatech intraoral radiographic sensor, Vatech, South Korea) and the technique of radiograph was paralleling technique using sensor holder (TROLLBYTE PLUS, TROLLDENTAL, UK) to ensure same position of cone through subsequent follow-up exposures | at 3 months, 6 months, 9 months, 12 months |
