About

alveolar ridge preservation using deep collagen layer, xenograft and collagen membrane seal versus the use of xenograft and collagen membrane seal alone. Measuring the clinical and radiographic alveolar ridge dimensional changes following after preservation at the time of implant placement

Full description

alveolar ridge preservation using deep collagen layer, xenograft and collagen membrane seal versus the use of xenograft and collagen membrane seal alone.

The primary objective of the study is measuring the clinical and radiographic alveolar ridge dimensional changes following the procedure 4 months post operatively

The secondary objective :

• Histological assessment of alveolar bone specimens to assess bone remodeling and new bone formation in both studied groups after four months.
• Patient satisfaction after implant placement

Enrollment: 20 patients

Sex: All

Ages: 20 to 45 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Systemically healthy patients (American Society of Anesthesiologists I; ASA I).

  • Patients diagnosed with single unrestorable molar teeth (socket type I) requiring extraction and implant placement (Elian et al.2007).

• Teeth free from any infection or periapical pathosis.

• Enough zone of keratinized tissue with at least 2mm.

• Good compliance with the plaque control instructions following initial therapy.

• Availability for follow up and maintenance program.

Exclusion criteria

• Bad oral hygiene.
• Presence of smoking habit.
• Presence of occlusal interferences
• Pregnant females
• Vulnerable group of patients (handicapped, mentally retarded and prisoners) (according to the recommendation of esthetical committee of Faculty of Dentistry Ain Shams University).
