Ridge Splitting Using Autogenous Bone Wedge Versus the Conventional Intercortical Augmentation Technique in Horizontally Deficient Anterior Maxilla

Not Applicable

Recruiting

• Conditions: Horizontal Ridge Deficiency
• Interventions: Procedure: autogenous bone wedge

• Registration Number: NCT06529653
• Lead Sponsor: Cairo University

Brief Summary

The current study aimed to evaluate both the quality and quantity of gained and maintained bone width after ridge splitting utilizing autogenic bone wedges versus mixed bone particles for horizontal ridge augmentation in the anterior esthetic zone.

Detailed Description

This randomized clinical study included 20 patients with a horizontally deficient ridge in the esthetic region. Two groups were divided according to the type of intercortical bone graft used after ridge splitting: 10 patients for each. (The intervention group) had grafting with autogenous bone wedges harvested from the chin, and (the control group) had mixed (autogenic and xenogenic) bone particles.

Inclusion Criteria

1. All patients possessed partially edentulous anterior maxillary ridge with the following criteria

   1. The anterior maxillary vertical dimension was more than ten mm measured from the alveolar crest to the basal bone of the maxilla.
   2. The horizontal alveolar dimension varies from 3-5 mm at the crest and 6-8 mm at the basal part of the ridge measured from the labial cortex to the lingual cortex.

2. All patients were free from any medical conditions that may affect bone healing .

3. No local pathosis that may interfere with bone healing.

4. No previous grafting procedures at the indicated edentulous ridge.

Arm && Interventions

Group	Intervention	Description
control group	autogenous bone wedge	the group used mixed autogenic and xenogenic bone particles that interposed between split cortices in anterior maxilla to manage the horizontal deficiency of the ridge
intervention group	autogenous bone wedge	the group using an autogenous bone wedge harvested from the chin interpositioned between split cortices in the anterior maxilla to manage the horizontal deficiency of the ridge.

Primary Outcome Measures

Name	Time	Method
bone width in (mm) by cone beam pre, immediate post operative and 6 months postoperative	6 months	after ridge augmentation in both groups, the bone width will be measured immediately postoperatively and 6 months postoperatively with cone beam and the measurements of the three intervals (pre-, immediate and 6 months postoperatively) will be compared in both groups to evaluate the amount of gained and maintained bone width

Secondary Outcome Measures

Name	Time	Method
percentage of areas of new bone (%)	6 months	The harvested core biopsies would be stained with H\&E and Massons trichrome stain and be microscopically examined to determine percentage areas of newly formed bone
