About

The aim of this study is to clinically and radiographically evaluate the dimensional changes of soft and hard peri-implant tissues around single immediate post-extraction implants in the esthetic zone.

Full description

to compare the efficacy of the socket shield technique in counteracting the dimensional changes of the soft and hard peri-implant tissues to filliing the buccal gap with xenograft.

• Population (P): Patients with single non-restorable tooth in the esthetic zone.
• Intervention (I): Immediate implant placement with socket shield technique.
• Comparator (C): Immediate implant placement and filling the buccal gap with xenograft.
• Primary Outcome (O): Pink Esthetic Score (PES) (Fürhauser et al., 2005).
• Time frame: 9 months (Chu et al., 2015).
• Study design: Randomized controlled clinical trial.

Enrollment: 22 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

1. Patient's age was 18 years or older.
2. Non-restorable tooth in the upper inter-bicuspid area.
3. Adequate bone volume for the placement of immediate implant.
4. Following tooth extraction, there was an intact socket bony wall (type I extraction socket).
5. Primary stability of the implant was achieved at the time of the implant placement.

Exclusion criteria

1. Patients who reported tobacco use in the past 5 years.
2. Patients who had severe periodontal destruction at the site of implant placement.
3. The presence of any signs of acute infection in the surgical site or the adjacent two natural teeth.
4. Patients who had history of any systemic disease that precludes the placement of implants.
5. Any disease that might affect bone metabolism as osteoporosis.
6. Patients taking medications that might affect bone turn over as bisphosphonates.
7. Physically or mentally handicapped patients.
8. Pregnant females.
9. Teeth with vertical root fractures on the buccal aspect
10. Teeth with any other pathologies affecting the buccal part of the root, for example, external or internal resorptions.
