Details and patient eligibility

About

Anterior maxilla (Esthetic zone) is very challenging area because of thin buccal plate of bone. After tooth extraction physiological process occur causing alteration of bone and soft tissue so, delayed placement of implant lead to loss of bone height and width. Immediate placement of implant is become essential to preserve the bone and soft tissue from loss.

Socket shield technique is a recent technique which is by sectioning the root and extraction of palatal part and leaving buccal part of the root with its attachment of periodontal ligament and vascularization still intact then placing implant in palatal socket. This technique allow preservation of buccal plate of bone and soft tissue with minimum loss allowing better result in esthetic zone.

Enrollment: 18 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Patients with badly broken teeth in upper esthetic zone with intact periodontal condition indicated for extraction, presence of at least 4 mm of bone beyond the root apex to guarantee implant primary stability, implant placement within the alveoli confines.
• Both sexes.
• No intraoral soft and hard tissue pathology.
• Physically able to tolerate conventional surgical and restorative procedures.
• Signing of an informed consent form.

Exclusion criteria

• Presence of fenestrations or dehiscence of the residual bony walls after extraction.
• Heavy smokers more than 20 cigarettes per day .(24)
• Patients with systemic disease that may affect normal healing e.g. uncontrolled diabetes.
• Psychiatric problems e.g. severe bruxism.
• Disorders to implant are related to history of radiation therapy to the head and neck neoplasia, or bone augmentation to implant site.
• Active infection in the teeth to be treated
• Vertical root fractures with displacement in the teeth of the surgical area
