Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • patients who are in need of a tooth extraction at the maxillary premolar, canine and incisor region, and subsequent single implant placement.
  • The reasons for extraction will include poor endodontic prognosis and/or unrestorable teeth (extensive caries, traumatic fractures, fractures of endodontically treated teeth, root perforation, root resorption with or without radiographic periapical lesion up to 3 mm in diameter). patients who are systemically healthy or with controlled common systemic conditions (controlled hypertension, controlled diabetes HbA1c up to 7 %).
  • adjacent teeth have to be present and the eligible tooth has esthetically acceptable buccal gingival margin position prior to surgery, compared to neighboring teeth and contralateral tooth, and adequate width of buccal keratinized gingiva(≥3mm).
  • level of radiographic bone level has the distance from CEJ to interproximal crest up to 4 mm.
  • Location of buccal alveolar crest has to be generally within 4 mm from the free gingival margin, verified after the extraction, before randomization; and fenestration, if present, up to 3mm in diameter at the apical part of the root and affecting less than 30% of the buccal socket wall.

Exclusion Criteria:

  • currently smoke exceeding 10 cigarettes/ day
  • severe parafunctional habits, malocclusion or intent of orthodontic therapy in the future and are pregnant.
  • teeth in the surgical site will be excluded if there is advanced periodontal disease or periapical lesion causing significant bony defects that are beyond the criteria mentioned at Section 3.3.
  • allergy to antibiotics contained in the ADM (Gentimicin, Cefoxitin, Lincomcin, polymixin B and Vancomycin) will not be included in the immediate implant combined with ADM group.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Ridge Dimension
Time Frame: baseline, 6 months after surgery
Change in ridge dimension is calculated as the value at 6 months minus the value at baseline. To take ridge dimension measurements, impressions were taken at baseline and 6 months, models were made from these impressions, the models were scanned, and then ridge dimension of scanned models was assessed using software. Ridge dimension was assessed at (and at 1mm increments below) the initial soft tissue margin.
baseline, 6 months after surgery
Change in Ridge Dimension
Time Frame: baseline, 12 months after surgery
Change in ridge dimension is calculated as the value at 12 months minus the value at baseline. To take ridge dimension measurements, impressions were taken at baseline and 12 months, models were made from these impressions, the models were scanned, and then ridge dimension of scanned models was assessed using software. Ridge dimension was assessed at (and at 1mm increments below) the initial soft tissue margin.
baseline, 12 months after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Gingival Level
Time Frame: baseline, 6 months after surgery
Change in gingival level is calculated as the value at 6 months minus the value at baseline. Gingival level is measured at three sites: mesial, mid-buccal and distal sites. Gingival level is measured from a notch on a custom fabricated stent to the mucosal margin.
baseline, 6 months after surgery
Change in Gingival Thickness
Time Frame: baseline, 6 months after surgery
Change in gingival thickness is calculated as the value at 6 months minus the value at baseline. Gingival thickness is measured using a stoppered endodontic file (#30) penetrating through the facial soft tissue 3 millimeters (mm) below the mid-buccal peri-implant mucosal margin.
baseline, 6 months after surgery
Change in Width of Keratinized Gingiva
Time Frame: baseline, 6 months after surgery
Change in width of keratinized gingiva is calculated as the value at 6 months minus the value at baseline.
baseline, 6 months after surgery
Change in Alveolar Bone Level (Marginal)
Time Frame: baseline, 6 months after surgery
Change in alveolar bone level is calculated as the value at 6 months minus the value at baseline. The bone level measurement, taken from the standardized periapical radiographs, was defined as the distance from the first bone to implant contact (IB) at either the mesial or the distal aspect of the implant to the implant platform. Specifically, marginal bone level was defined as the distance between the vertical implant bone level (IB; the first bone to implant contact) and implant platform (IP). Crestal bone level was defined as the distance between the interproximal crestal bone level (IC) and implant platform (IP).
baseline, 6 months after surgery
Change in Alveolar Bone Level (Crestal)
Time Frame: baseline, 6 months after surgery
Change in alveolar bone level is calculated as the value at 6 months minus the value at baseline. The bone level measurement, taken from the standardized periapical radiographs, was defined as the distance from the first bone to implant contact (IB) at either the mesial or the distal aspect of the implant to the implant platform. Specifically, crestal bone level was defined as the distance between the interproximal crestal bone level (IC) and implant platform (IP).
baseline, 6 months after surgery
Change in Bone Dimension
Time Frame: baseline, 6 months after surgery
Change in bone dimension is calculated as the value at 6 months minus the value at baseline. To measure bone dimensions, bone dimensions on cone beam computed tomography (CBCT) images were assessed using software. Bone dimension was assessed at the initial buccal crestal bone level (and at 1mm increments below).
