Keratized Mucosa in CG Implant Placement: CTG vs Flapless

Width of Keratinazed Mucosa in Immediately Loaded Posterior Implant Restorations Treated With Different Surgical Approaches: Randomized Clinical Study.

The present study will evaluate the difference in terms of keratinazed mucosa (KM) in computer guided implant placement with immediate loading, comparing a flapless approach to flap surgery with connective tissue graft.

Inclusion Criteria:

• Age 18+
• Patients with partial edentulism in the posterior region (4-7) upper or lower for at least 3 months
• Patient whose tomographic examination shows adequate bone volumes for computer guided placement of a standard diameter implant (> 3.5 mm) without the need for bone regeneration procedures
• Patients who have accepted informed consent and participation in the study
• Patients who do not have exclusion criteria

Eclusion Criteria

• Patients who refuse to co-operate

• Systemic conditions of exclusion:

  • Medical conditions requiring prolonged use of steroids

  • Pregnant or breastfeeding patient
  • History of uncontrolled endocrine disorders
  • Physical handicaps that hinder proper oral hygiene
  • Use of experimental devices or drugs within 30 days prior to implant placement surgery
  • Alcoholism or drug abuse
  • Smokers of> 10 cigarettes per day or the equivalent cigar or> 10 tobacco-based chewings per day
  • Conditions or circumstances that prevent the completion of participation in the study or interfere with the analysis of the study results

Local exclusion conditions:

• Local inflammation, including untreated periodontitis
• Patients with erosive lichen planus
