Comparison Between Socket Shield and Conventional Techniques in Immediate Implant Placement.

August 10, 2026 updated by: Omar Ibrahim Wahedi, Minia University

Comparative Study Between Using Socket Shield And Conventional Techniques In Immediate Implant Placement (A Randomized Clinical Trial)

The goal of this randomized clinical trial is to compare whether immediate implant placement using the socket-shield technique can better preserve bone density, bone level, and peri-implant tissue health compared to conventional immediate implant placement in patients requiring tooth extraction in the maxillary esthetic zone.

This study is conducted in systemically healthy adult patients aged 20-60 years who have non-restorable maxillary anterior teeth indicated for immediate implant placement.

The main questions this study aims to answer are:

Does the socket-shield technique result in better peri-implant bone density and bone level preservation compared to the conventional immediate implant technique?

Does the socket-shield technique lead to improved clinical peri-implant parameters, including probing depth, bleeding on probing, keratinized tissue width, and soft tissue thickness?

participants will be divided into two groups: (both groups will receive immediate implant placement of a tooth requiring extraction in the maxillary esthetic zone.) First group: will recieve immediate implant using conventional technique. second group: will recieve immediate implant using socket shield technique.

Participants will:

  • Undergo clinical and radiographic examinations, including cone beam computed tomography (CBCT).
  • Receive immediate implant placement using either the conventional technique or the socket-shield technique.
  • Be followed up clinically and radiographically for 9 months to assess bone and soft tissue healing.
  • Attend regular postoperative and follow-up visits for evaluation of implant stability and peri-implant tissue health.

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.

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

No

Description

Inclusion Criteria:

  • Patients aged between 20 and 60 years of both genders
  • All participants should be systemically healthy, as assessed using the dental modification of the Cornell Medical Index.
  • Gingival and periodontal health to be confirmed according to the criteria outlined in the new classification system proposed by Caton et al. (2018).
  • Presence of non-restorable teeth due to trauma, complicated crowns or root fractures.
  • Presence of extensive destructive caries making the tooth unsalvageable, particularly in esthetic zones.
  • Clinical indication for immediate implant placement, especially in cases where minimizing post-extraction bone resorption and soft tissue collapse is critical.
  • Availability of adequate interocclusal space to accommodate the necessary prosthetic components without occlusal interference.

Exclusion Criteria:

(for socket-shield technique)

  • Pregnant female.
  • Patients with parafunctional habits (e.g., bruxism, clenching).
  • Smokers.
  • Teeth with clinical mobility.
  • Teeth with root fractures extending below the alveolar bone level.

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
Change in Bone Density Around Immediate Implants.
Time Frame: At baseline of implant placement then after 9 months

Assessment of bone mineral density using Gray scale values (GSV) derived from Cone Beam Computed Tomography (CBCT) scans. Measurements will be evaluated at the buccal bone adjacent to the retained root fragment (Socket Shield Group) and adjacent to the implant surface (Conventional Immediate Placement Group). The change will be calculated by subtracting the baseline value from the 9-month follow-up value.

Unit of Measure: Gray scale values Time Frame: Baseline to 9 months post-implant placement

Measure Description:

Bone density measured using average gray values extracted from CBCT DICOM files at the buccal aspect of the implant site. Gray scale values reflect the radiographic attenuation/pixel intensity of the surrounding bone.
At baseline of implant placement then after 9 months
Change in Marginal Bone Level Around Immediate Implants.
Time Frame: At baseline of implant placement then after 9 months.
  • Linear measurement of the distance from the implant platform to the first bone-to-implant contact point to assess crestal bone stability.
  • Unit of measure : Millimeters (mm).
At baseline of implant placement then after 9 months.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Probing Depth (PD)
Time Frame: 3 months, 6 months, and 9 months post-surgery.

Measurement of the distance from the peri-implant mucosal margin to the bottom of the clinical pocket using a calibrated periodontal probe.

Unit of Measure: Millimeters (mm)

Modified Gingival Index (MGI)
Time Frame: 3 months, 6 months, and 9 months post-surgery.

Assessment of the visual signs of inflammation of the peri-implant soft tissues. Scores range from 0 to 4 (0 = Normal, 1 = Mild inflammation, 2 = Mild inflammation with color change, 3 = Moderate inflammation, 4 = Severe inflammation).

Unit of Measure: Score on a scale (0-4)
3 months, 6 months, and 9 months post-surgery.
Modified Plaque Index (MPI)

Unit of Measure: Score on a scale (0-3)
3 months, 6 months, and 9 months post-surgery.
Gingival Thickness (GT)
Time Frame: Baseline, 3 months, 6 months, and 9 months post-surgery.
