About this study

The study compares immediate, early, and conventional loading of UV-photofunctionalized dental implants placed in the posterior maxilla. Implant stability and peri-implant tissue changes will be evaluated clinically and radiographically

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • • Patients with missed single tooth or multiple teeth in posterior maxilla
  • Patients Free from any para-functional habits.
  • Patient with Adequate inter-arch relation and inter-occlusal space to accommodate the prosthetic restoration.
  • Patient with good oral hygiene.
  • Patients Willing to participate in the study's follow-up intervals.

Exclusion criteria

  • • Patients with any local or systemic disease that absolutely contraindicate implant placement or surgery.
  • Pregnancy.
  • Patients with any pathological lesion or aggressive periodontal disease at the planned surgical site.
  • Patients on drugs that could affect bone healing process such as bisphosphonate.
  • Smokers.
  • Uncooperative patients.

Treatment and study plan

Immediate loading of UV-photofunctionalized dental implants

Procedure

Immediate loading of UV-photofunctionalized dental implants placed in the posterior maxilla.

Early loading of UV-photofunctionalized dental implants

Procedure

Early loading of UV-photofunctionalized dental implants placed in the posterior maxilla.

Conventional loading of UV-photofunctionalized dental implants

Procedure

Conventional loading of UV-photofunctionalized dental implants placed in the posterior maxilla

Primary outcomes

  1. Implant Stability

    Time frame: -Immediately after impant placement -immediately after loading -3 months after loading - 6 months after loading

    Implant stability will be evaluated using Osstell device based on resonance frequency analysis (ISQ values).

  2. Hard Tissue (peri-implant bone)

    Time frame: - Immediately Postoperative (baseline) - 3 months after loading. - 6 months after loading.

    Marginal bone loss will be assessed using CBCT measured in mm.

Secondary outcomes

  1. Soft Tissue

    Time frame: At 6 months after loading.

    The peri-implant mucosa will be evaluated for signs of inflammation using the Modified Sulcus Bleeding Index (mSBI).

  2. Peri-implant probing depth

    Time frame: At 6 months after loading.

    Probing depth will be assessed using a calibrated periodontal probe with light pressure and measured in mm.
