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

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

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.

Study Overview

• Status: Recruiting
• Conditions: Horizontal Ridge Deficiency
• Intervention / Treatment: Procedure: autogenous bone wedge

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.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: Adult
• Accepts Healthy Volunteers: Yes

Description

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.

   Exclusion Criteria:

1- Patients suffering from any systemic disease that may affect bone healing. 2- Patients with less than 3mm labio palatal alveolar ridge width. 3- Ridge with inadequate vertical bone height. 4- Presence of any local pathosis that may interfere with bone healing. 5- Patients unable to continue the whole follow up.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Other: intervention group; 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.	Procedure: autogenous bone wedge; autogenous bone block harvested from chin and adjusted to be wedged intercortical in split ridge
Other: control group; 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	Procedure: autogenous bone wedge; autogenous bone block harvested from chin and adjusted to be wedged intercortical in split ridge

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
bone width in (mm) by cone beam pre, immediate post operative and 6 months postoperative	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	6 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
percentage of areas of new bone (%)	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	6 months
