About this study

Twenty patients, who are candidates for immediate implant placement, will participate in this prospective clinical trial.

Group 1(10 patients) :

immediate implant placement with bone graft and collagen memebrane outside the buccal plate

Group 2 (Control group)(10 patients) :

immediate implant placement with bone graft and collagen memebrane inside the buccal plate assessment of the buccal bone thickness assessment of soft tissue thickness

  • Esthetic outcome evaluation Will be done using the root coverage esthetic score (Cairo et al. 2009) that include

Both evaluations will be done at 3, 6 and 9 months

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

  • Systemically free patients (American Society of Anesthesiologists I; ASA I).
  • Age range (20 -50) years.
  • Good compliance with the plaque control instructions following initial therapy.
  • Patients diagnosed badly decayed tooth in esthetic zone indicated for immediate implant placement
  • Availability for follow up and maintenance program.

Treatment and study plan

Collagen membrane inside

Procedure

during immediate implant placement the collagen membrane will be placed in the jumping gap

Collagen membrane outside

Procedure

during immediate implant placement the collagen membarne will be placed on the surface of the buccal plate of bone

Primary outcomes

  1. buccal plate of bone thickness

    Time frame: baseline 12 months

    assessment of the buccal plate of bone will be determined in mm from CBCT

Secondary outcomes

  1. soft tissue thickness (Volumetric assessment)

    Time frame: baseline, 6 and 12 months

    Preoperative scanning will be done. At 6,12 months after surgical procedure the same procedure will be done to determine the soft tissue thickness after the surgery. The difference between the tissue thickness before and after
