Healthy volunteers accepted: No

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

Inclusion criteria

  • Presence of unrestorable bilateral anterior teeth.
  • Harmonious gingival contour and thick gingival phenotype
  • Minimum 4 mm of apical bone and 2 mm of intact labial plate
  • Absence of periapical pathology

Exclusion criteria

  • Systemic conditions affecting osseointegration or healing
  • Active oral infections or periodontal disease
  • Dehiscence or fenestration defects
  • Poor oral hygiene or heavy smoking

Treatment and study plan

Immediate Implant Placement

Procedure

Tooth extraction was performed atraumatically on one side, followed by immediate implant placement, right after extraction.

Early Implant Placement

Procedure

The tooth was extracted, and the implant was placed four weeks later (early placement).

Primary outcomes

  1. Marginal Bone Loss

    Time frame: up to 12 months

    Cone beam computed tomography (CBCT) scans were obtained at the time of final restoration and post-placement. Measurements were made (in mm) from the implant platform to the most coronal bone level using OnDemand3D software. Each scan was oriented to align the implant with the axial plane. Measurements were performed by a single calibrated examiner to a precision of 0.01 mm.

  2. Implant stability

    Time frame: up to 12 months

    Implant Stability Quotient (ISQ) values were measured using Osstell. To ensure accuracy, the probe was positioned at a 90° angle and 3 mm above soft tissue level, as recommended in previous protocols. Osstell's patented technology uses the ISQ scale, with values ranging from 1 to 100, where higher values indicate greater stability
