September 20, 2025 updated by: Ain Shams University

Influence of Digitalized Impression on Single Peri-implant Soft Tissue Profile in Esthetic Zone and Patient Satisfaction: A Randomized Controlled Trial

This randomized controlled clinical study will be carried out to compare the digital with conventional impression procedures for the restoration of single implants in an esthetic zone by assessing:

  1. pink esthetic score (PES) of peri-implant soft tissue profile and marginal bone loss (MBL) as primary objectives
  2. Patients' satisfaction and clinical outcomes as secondary objectives

Study Overview

Status

Completed

Detailed Description

fourteen patients with single nonrestorable tooth in the esthetic zone participated in the study and were replaced with immediate implants with immediate customized provisional restoration after 3 months they recalled for the impression, seven with digital and the others with conventional and evaluated.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Digital impression with intraoral scanner
included seven participants with non-restorable tooth in esthetic zone replaced by immediate implants receiving a single all ceramic crown fabricated with full digital procedure consisting of digital impression with intraoral scanner, and Computer Aided Design/ Computer Aided Manufacture (CAD/CAM) procedure.
Immediate implant placement with customized healing abutment and after three months placement all ceramic crown by digital impression using intra oral scanner
Other Names:
  • implant placement
Active Comparator: conventional impression technique
included seven participants with non-restorable tooth in esthetic zone replaced by immediate implants receiving a single all ceramic crown fabricated with Conventional impression-taking with polyvinyl siloxane, plaster model pouring and lost-wax casting technique
Immediate implant placement with customized healing abutment and after three months placement of all ceramic crowns by conventional impression
Other Names:
  • implant placement
  • impression copying

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
pink esthetic score
Time Frame: at the baseline(time of impression), second time was one week later (immediately) after crown placement, third time was one month later after crown placement , fourth time was three months later after crown placement

The pink esthetic score is based on seven variables:

  • Mesial papilla
  • Distal papilla
  • Soft-tissue level
  • Soft- tissue contour
  • Alveolar process deficiency
  • Soft-tissue color and texture Each variable was assessed with a 2-1-0 score, with 2 being the best and 0 being the poorest score
at the baseline(time of impression), second time was one week later (immediately) after crown placement, third time was one month later after crown placement , fourth time was three months later after crown placement
marginal bone loss
Time Frame: immediately after crown placement (baseline), then three months after crown placement
described by millimeter using paralleling technique
immediately after crown placement (baseline), then three months after crown placement

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
patient satisfaction
Time Frame: after crown placement

satisfaction questionnaire modified from based on 10 specific questions.

The questions were as follows:

  1. Are you satisfied with the treatment? with 0 = very dissatisfied and 100 = very satisfied
  2. Did you experience discomfort during the impression-taking? with 0 = high discomfort and 100 = no discomfort
  3. Did you experience gag reflex/nausea during the impression-taking? with 0 = strong gag reflex/nausea, and 100 = no gag reflex/nausea
  4. How comfortable was the impression procedure? with 0 = uncomfortable and 100 = comfortable
  5. Does your implant-supported restoration function well? with 0 = bad function and 100 = well function
after crown placement
plaque index
Time Frame: Immediately after crown placement (baseline), one months later , and finally three months after crown placement

0 = No plaque in gingival area.

  1. = A film of plaque adhering to the free gingival margin and adjacent area of tooth. The plaque may be recognized only by running a probe across the tooth surface.
  2. = Moderate accumulation of soft deposit within the gingival pocket and on the gingival pocket and on the gingival margin and/or adjacent tooth surface that can be seen by naked eye.
  3. = Abundance of soft matter within the gingival pocket and/or on the gingival margin and adjacent tooth surface.

    • of sites positive for dental plaque will be calculated for each case.
Immediately after crown placement (baseline), one months later , and finally three months after crown placement
gingival index
Time Frame: Immediately after crown placement (baseline), one months later , and finally three months after crown placement

0 = Normal gingiva.

  1. = Mild inflammation, slight change in color, slight edema; no bleeding on probing.
  2. = Moderate inflammation, redness, edema, and glazing; bleeding on probing.
  3. = Sever inflammation, marked redness and edema, ulceration; tendency to spontaneous bleeding.
Immediately after crown placement (baseline), one months later , and finally three months after crown placement
