Outcome Measures

Primary Outcomes (4)

  • Global Coronal Deviation

    The deviation between the planned and actual implant positions at the coronal point will be assessed using CBCT superimposition, measured in mm.

    Immediately after implant placement.

  • Global Apical Deviation

    The deviation between the planned and actual implant positions at the apical point will be assessed using CBCT superimposition, measured in mm.

    Immediately after implant placement.

  • Angular Deviation

    The angular deviation between the planned and actual implant axes will be assessed using CBCT superimposition, measured in degrees (°).

    Immediately after implant placement.

  • Vertical (Depth) Deviation

    The deviation in implant depth between the planned and actual implant positions will be assessed using CBCT superimposition, measured in mm.

    Immediately after implant placement.

Secondary Outcomes (5)

  • Surgical Time

    During the surgical procedure.

  • Prosthetic fit of the prefabricated 3D-printed restoration

    Immediately after provisional crown placement.

  • Ease of Guide Use (Operator Assessment)

    Immediately after implant placement.

  • Conversion to Freehand Surgery

    During implant placement.

  • Intraoperative Patient Comfort

    Immediately after implant placement.

Study Arms (2)

Study Group 1 (Sleeved Guide)

EXPERIMENTAL

40 immediate dental implants will be placed using a conventional sleeved static surgical guide in the maxillary premolar region. Silicate-added β-tricalcium phosphate graft will be used to fill the peri-implant gap, followed by placement of a provisional crown.

Procedure: Conventional Sleeved Static Surgical Guide

Study Group 2 (Sleeveless Guide)

EXPERIMENTAL

40 immediate dental implants will be placed using a sleeveless static surgical guide in the maxillary premolar region. Silicate-added β-tricalcium phosphate graft will be used to fill the peri-implant gap, followed by placement of a provisional crown.

Procedure: Sleeveless Static Surgical Guide

Interventions

Immediate implant placement in the maxillary premolar region using a conventional sleeved static surgical guide, with silicate-added β-tricalcium phosphate grafting of the peri-implant gap and placement of a provisional crown.

Study Group 1 (Sleeved Guide)

Immediate implant placement in the maxillary premolar region using a sleeveless static surgical guide, with silicate-added β-tricalcium phosphate grafting of the peri-implant gap and placement of a provisional crown.

Study Group 2 (Sleeveless Guide)

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Patients with non-restorable teeth in premolar area requiring dental extraction.
  • Age range: from18 to 50 years.
  • Adequate inter-arch relation and inter-occlusal space to accommodate the prosthetic restoration.
  • Jumping gap more than 2mm.
  • Patients with good oral hygiene.
  • Patients willing to participate in the study's follow-up intervals.

You may not qualify if:

  • Patients with any pathological lesion or aggressive periodontal disease at the planned surgical site impaired the immediate implant placement.
  • Alcohol or drug abuse.
  • Smokers.
  • Patients with systemic diseases that absolutely contraindicate implant placement (bleeding disorders, immunosuppression,…etc.)
  • Pregnancy.
  • Patients with para-functional habits (bruxism and clenching).
  • Lack of motivation or inability to maintain good oral hygiene.
