  • The tooth that required extraction showed no clinical or radiographic signs of acute infection.
  • There was at least 5 mm of available bone between the superior border of the inferior alveolar canal and the root apex.
  • At least 8 mm inter-arch space for the prosthesis.
  • Patients were free of systemic conditions that absolutely contraindicate implant insertion.
  • Patients with good oral hygiene.

Treatment and study plan

immediate implant with dentin-derived barrier membrane

Procedure

immediate implant with dentin-derived barrier membrane with allograft covering any peri-implant defect and jumping gap.

immediate implant with eprf membrane

Procedure

immediate implant with eprf membrane with allograft covering any peri-implant defect and jumping gap.

Primary outcomes

  1. Implant stability

    Time frame: 12 months

    The implant stability was evaluated immediately postoperatively and after 3, 6, and 12 months. An Osstell Mentor device (Osstell, Savadaled, Sweden; Integration Diagnostics) was utilized to assess implant stability utilizing resonance frequency analysis (RFA). Measurements were made at 90° in four different directions in order to calculate the RFA value. The implant stability quotient (ISQ) was calculated by averaging the results for each implant.
