Zirconia Vs Titanium Implants in Deficient Ridges

Not Applicable

• Conditions: Alveolar Bone Loss; Periodontitis
• Interventions: Device: Titanium implant; Device: Zirconia implant

• Registration Number: NCT04375839
• Lead Sponsor: SVS Institute of Dental Sciences

Brief Summary

The aim of this study is to evaluate clinically and radiographically soft tissue around single-implant crowns and peri-implant bone resorption respectively by using zirconia implants or titanium implants in horizontally deficient partially edentulous ridges.

Detailed Description

Experimental: Main treatment group Zirconia implants will be placed in a prosthetically guided position in horizontally deficient ridges in main treatment group.

Active Comparator: Control group Titanium implants will be placed in a prosthetically guided position in horizontally deficient ridges in control group.

Arm && Interventions

Group	Intervention	Description
Control group	Titanium implant	Titanium implants will be placed in a prosthetically guided position in horizontally deficient ridges in control group.
Main treatment group	Zirconia implant	Zirconia implants will be placed in a prosthetically guided position in horizontally deficient ridges in main treatment group.

Primary Outcome Measures

Name	Time	Method
Peri-implant bone resorption	Baseline to 6 months	measured in terms of vertical bone levels present mesial and distal to implant which will be measured by comparing CBCT
Evaluation of the soft tissue around single implant crowns	Baseline to 6 months	Pink Esthetic Score (0-2; increasing scores means improvement in clinical outcomes) is used to evaluate the soft tissue around single implant crowns that might change over time at 3 months and 6 months.

Secondary Outcome Measures

Name	Time	Method
Implant survival rate	Baseline to 6 months	Implant survival rate before and after prosthetic loading based on Criteria: A) Persistent pain or dysesthesia B) Peri-implant infection with suppuration C) Absence of mobility D) Absence of continuous peri-implant radiolucency, but with peri-implant bone resorption assessed using dichotomous scale.
