About this study

Volumetric analysis of peri-implant soft tissues after 3 months of the use of a prefabricated healing abutment with scan peg with convex emergence profile in comparison to customized healing abutment with concave emergence profile.

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • Adult patients who are classified as ASA I or II physical status and require mandibular single implants (single missing mandibular posterior teeth) with:
  • Proper bone height and width.
  • Adequate zone of keratinized tissue (at least 2 mm)

Exclusion criteria

  • Any systematic disease as uncontrolled diabetes mellitus or metabolic bone diseases
  • Pregnancy and Lactation
  • A history of head and neck radiation treatment.
  • Chronic periodontal diseases.
  • Poor oral hygiene (Silness-Löe plaque index score 2 and 3)
  • Parafunctional habits.

Treatment and study plan

Prefabricated healing abutment with scan peg

Other

12 participants will receive single posterior implants by fully guided implant protocol followed by placement of prefabricated healing abutment with scan peg having convex emergence profile

Customized healing abutment

Other

12 participants will receive single posterior implants by fully guided implant protocol followed by placement of custom healing abutment having concave emergence profile

Primary outcomes

  1. Measurement of peri-implant soft tissues volume

    Time frame: 3 months

    Each participant will undergo volumetric analysis of peri-implant soft tissues after 3 months healing either after using prefabricated healing abutment with scan peg in comparison to customized healing abutment using a 3D meteorology software (GOM inspect). It will be measured in millimeter cube
