Beskrivelse

Inclusion Criteria:

  • Systemic healthy patients

    • Patients aged > 25 years
    • Patients suffering from stage II periodontitis with grade B were included in this study, according to 2017 world workshop classification of periodontal disease (Papapanou et al. 2017).
    • Patients with interdental clinical attachment loss (CAL) of 3-4 mm
    • No history of previous periodontal therapy.
    • No taken medications known to interfere healing or periodontal tissue health such as anticonvulsants, calcium channel blockers, or immunosuppressant drugs.
    • No previous periodontal surgery at involved sites.
    • Good oral hygiene and good compliance with the plaque control instructions following initial therapy.
    • Neither taken antibiotics within the last three months nor nonsteroidal anti-inflammatory drugs within the last three months
    • Absence of diseases or conditions that would interfere with wound healing such as diabetes mellitus or coagulation disorders
    • Absence of oral mucosal inflammatory conditions such as aphthous ulcers or lichen planus.

Exclusion Criteria:

  • Smoking habits

    • Pregnant and lactating mothers
    • Patients who have been received periodontal surgery in the study area during the last 6 months

  • Tooth preparation will be performed following standardized prosthodontic guidelines
  • 1.5-2 mm occlusal reduction
  • 1-1.2 mm axial reduction
  • Chamfer finish line
  • Digital impressions will be obtained using an intraoral scanner.
  • CAD/CAM Milled and 3D printed Provisionals will be fabricated

• will be measured clinically using UNC periodontal probe from cemento enamel junction to depth of periodontal pocket
Day 0 - month 3
bleeding on probing (BOP)
Tidsramme: Day 0 - month 3

will be measured clinically using UNC periodontal probe. Count the bleeding points and divided them by the total number of patients' teeth in the oral cavity and multiply by 100 to make the percent.

localized less than 30% and generalized greater than or equal 30%
Day 0 - month 3
Plaque index (PI)
Tidsramme: Day 0 - month 3

plaque index

This clinical method assesses the thickness of plaque specifically at the cervical margin (gumline).

The Scoring Scale (0 to 3):

0: No plaque in the gingival area.

  1. A film of plaque visible only by running a probe across the tooth surface or after using a disclosing solution.
  2. Moderate accumulation of plaque visible to the naked eye along the gumline.
  3. Abundance of soft matter within the pocket or along the gumline
Day 0 - month 3

Surface roughness
Tidsramme: Day 0 - month 3
will be measured using a surface roughness measuring instrument (or profilometer) is a precision device used to evaluate the texture of a material by measuring microscopic peaks and valleys. They are essential for quality control in manufacturing to ensure components meet strict friction, wear, and coating adhesion standards.
