Buccal Cortical Separation and Lateralization for Horizontal Ridge Augmentation

Study Overview
=================
Brief Summary
-----------------
Cases with horizontal ridge deficiency less than what is possible for ridge splitting were recruited and the buccal cortex was totally separated and lateralized at the desired distance for augmentation

Official Title
-----------------
Qualitative and Quantitative Assessment of Autogenous Versus Xenogenic Horizontal Ridge Augmentation After Mandibular Ridge-split With Buccal Cortical Lateralization: A Randomizedcontrolled Trial

Conditions
-----------------
Horizontal Ridge Deficiency

Intervention / Treatment
-----------------
* Procedure: Lateralized buccal cortex with xenograft
* Procedure: Lateralized buccal cortex with autogenous particulate


Participation Criteria

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Lateralized buccal cortex group with xenograft<br>the buccal cortical bone was osteotomized and separated to be fixed in a lateralized position at the desired distance and the gap filled with Xenograft | Procedure: Lateralized buccal cortex with xenograft<br>* the buccal cortex of the deficient ridge was separated and lateralized then fixed at the desired distance<br>|
| Active Comparator: lateralized buccal cortex with autogenous particulate<br>the buccal cortex was lateralized same as in the interventional group but the gap filled with autogenous particulate | Procedure: Lateralized buccal cortex with autogenous particulate<br>* lateralized buccal cortex with autogenous particulate<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in horizontal bone gain | the net average bone gain (in millimeters) was calculated: by calculating the difference between the immediate post operative bone width measured on the Immediate CBCT and the six months bone width measured on the six months CBCT | six months after the operation | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Bone area percent | histomorphometric analysis of core biopsies was done at the time of implant insertion to determine the bone area percent at the implant sites | Six months after the operation |
