About this study

Immediate implant placement in molar extraction sockets poses challenges related to soft-tissue closure, jumping distance, and peri-implant tissue stability. Socket sealing abutments (SSA) have recently been introduced to enhance soft-tissue healing and maintain peri-implant architecture, with or without adjunctive bone grafting.

Who can participate

Healthy volunteers accepted: Yes

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

Inclusion criteria

  • Patients with non-restorable maxillary or mandibular molars indicated for extraction and replacement with implants
  • Age between 18-45 years
  • Sufficient inter-arch space to accommodate the future prosthesis
  • Good oral hygiene
  • Free from systemic diseases
  • Patients with jumping space > 2 mm

Exclusion criteria

  • Presence of any pathological lesion or root tips at the planned surgical site
  • Aggressive periodontal disease
  • Inadequate bone height or thickness for implant placement
  • Alcohol or drug abuse
  • Systemic diseases that contraindicate implant placement (e.g., osteoporosis, active cancer)
  • Pregnancy
  • Para-functional habits (e.g., bruxism, clenching)
  • Patients wearing orthodontic appliances

Treatment and study plan

Immediate Molar Implant Placement with Grafting Material

Procedure

Participants will receive immediate molar implant placement after tooth extraction. A socket sealing abutment will be placed, and the extraction socket will be filled with an appropriate grafting material to promote bone preservation and enhance soft tissue healing. Standard post-operative care will be provided.

Immediate Molar Implant Placement without Grafting Material

Procedure

Participants will receive immediate molar implant placement after tooth extraction. A socket sealing abutment will be placed, without adding any grafting material. Standard post-operative care will be provided.

Primary outcomes

  1. soft tissue changes

    Time frame: Baseline,3 month,6month

    Optical scans of the patients' impressions were obtained immediately after surgery (baseline) and at 3- and 6-month follow-up intervals. For each patient, the baseline STL file was digitally superimposed onto the corresponding 3- and 6-month STL files using dedicated image analysis software to evaluate changes in the peri-implant soft tissues over time.

    A standardized two-dimensional bucco-lingual cross-sectional image was generated along the long axis of the implant. Buccal and lingual/palatal soft tissue dimensional changes were assessed by measuring the linear distance between baseline and follow-up(3,6month) soft tissue profiles at 1, 2, 3, and 4 mm apical to the GM. Mid-buccal gingival recession was evaluated by measuring the vertical change in the position of the gingival margin at 3,6month.

Secondary outcomes

  1. Dental implant stability assessed by resonance frequency analysis (ISQ)

    Time frame: basline 3,6 months

    Implant stability will be measured using resonance frequency analysis with the Osstell device. ISQ values will be recorded immediately 3,6-month follow-up visit.
