Simultaneous Implant Placement With Vertical and Horizontal Bone Augmentation

November 20, 2025 updated by: Walid Elamrousy, Kafrelsheikh University

Simultaneous Versus Staged Implant Placement With Vertical and Horizontal Bone Augmentation Using Autogenous Cortical Bone Plates Combined With a Mixture of Platelet-rich Fibrin and Allobone Grafts.

The purpose of this study was to report the clinical and radiographical outcomes of using autogenous cortical bone plates combined with sticky allogenic bone graft for augmenting maxillary anterior atrophic combined horizontal and vertical ridge defects with simultaneous versus staged implant placement.

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Sufficient alveolar ridge is a prerequisite for successful implant stability, atrophic ridges defects make the placement of regular implants challenging. A variety of materials and surgical techniques are available for bone augmentation procedures prior implant placement. The present study evaluated the effect of sticky allogenic bone graft for the horizontal and vertical ridge augmentation with simultaneous implant placement using autogenous cortical bone plates in maxillary anterior atrophic ridge defects.

Forty-two patients, with severe maxillary anterior horizontal and vertical atrophic ridge deficiencies were randomly assigned to two groups: staged approach group and simultaneous implant placement group. The two groups were grafted using bone plated buccally and palatally and the defect between plates was grafted by sticky allogenic bone graft. Radiographic examination was performed immediately before bone grafting procedure and at 6, 12 months postoperatively, to evaluate the change of bone width and height.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Good general health at the time of surgery
  • At least 3 months of healing after tooth extraction
  • Horizontally and vertical compromised alveolar ridges

Exclusion Criteria:

  • Thick cortex in the labial/buccal with less cancellous bone inside;
  • Obvious undercut on the labial/buccal side

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Staged implant placement approach
the bone defect was grafted using bone plates buccally and palatally and the defect between plates was grafted by sticky allogenic bone graft. 6 months later the implant was placed in the grafted site.
Procedure: implant placement 6 months after ridge augmentation
the deficient ridge was grafted first followed by implant placement after 6-monthes
Experimental: Simultaneous implant placement approach
the bone defect was grafted using bone plates buccally and palatally and the defect between plates was grafted by sticky allogenic bone graft combined with simultaneous implant placement.
Procedure: implant placement Simultaneously with ridge augmentation
the deficient ridge was grafted and followed by implant placement simultaneously

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Stability Quotient of Implants (SQI)
Time Frame: 12-month.
The implant stability was recorded using Osstell TM. Following implant insertion, SQI readings were taken immediately, then again after six and twelve months.
12-month.
Horizontal bone dimensions (HBDs)
Time Frame: 12-month.
The HBD alterations were assessed by measuring horizontal spacing between the external edges of labial and palatal bony plates at a level 2mm apical of the fixture platform.
12-month.
Peri-implant Bone Density (PBD)
Time Frame: 12-month.
For consistent measurement of the PBD, 1-mm-diameter Region of interest (RI) was selected and traced 1.2 mm distant from the fixture on the cross-sectional slices followed by counting the threshold pixels inside the RI.
12-month.
