Detailed Description
Implant became a treatment modality for replacing missing or non-restorable teeth, providing clinical success rate and esthetic outcome. (1) In esthetic zone the main goal is not only the preservation of function but also the preservation of the esthetics. The esthetic outcome of implant supported restoration depend on the soft tissue volume and the soft tissue contour. (2) The placement of immediate implant after tooth extraction was proved as a very high success rate treatment modality. It provided several advantages such as reduction of the time between tooth extraction and the placement of prosthesis, reduction of the number of surgical treatments (3) and increase osteointegration between bone and implant surface (4).
Considering the survival rate of immediate implantation versus delayed implantation there is no significant difference with an overall success rate of 99.6%, it is just considered as a successful treatment modality, based on 802 implants (5).
On the other hand disadvantage related to esthetic outcome has been reported, showing facial gingival recession following the first year of function due to labial bone plate resorption. (6, 2).
A systematic review by Sanz et al.,(2012) compared the reduction of bone height and bone width between two groups the control group was delayed implant placement and the studied group was immediate implant placement and the mean difference between groups was of 13.11% (95% CI: from 3.83 to 22.4; P = 0.057) and 19.85% (95% CI: from 13.85 to 25.81)respectively, concluding that the early placement of dental implants after tooth extraction offers advantages in terms of soft and hard tissue preservation, compared with delayed implant placement , which affect the aesthetic (7 ) As a sequence of dimensional ridge alterations that occur following tooth extraction many studies reported a recession of marginal peri-implant mucosa, which affect the aesthetic outcome (8, 9, and 10).
A study made by Migliorati et al., (2015) between two groups, the control group (immediate loading implant treated without raising a flap) and the test group (immediate loaded implant treated with sub-epithelial connective tissue graft (SCTG) using the tunnel technique in the labial area) Both groups (47 implants) received deproteinized bovine bone minerals and implants were successfully integrated with a follow up period 2-year examination . Moreover the mean recession in the control group was 0.71mm (17.58%), one third of the control group reported recession >1mm, and mean pink aesthetic score (PES) was 6.65, resulting in bad aesthetic. The test group showed an increase of the keratinized mucosa (KM) with a mean of 34.29% (0.5mm) and a mean recession of 0.2mm (10.01%), only one case (4%) showed recession >1mm and the mean PES was 8. The thickening of soft tissue by the addition of SCTG, lead to compensation and maintenance of the loss of bone volume in the labial area (11).
The addition of sub epithelial connective tissue graft (SCTG) to the immediate implant was suggested for facial gingival biotype conversation. It was proved to be successful in preserving soft tissue levels. (12)
A systematic review was made to investigate if the addition of SCTG overcome the disadvantage of placement of immediate implant only or not, but unfortunately the included studies had different techniques and the number of the patients in those studies was few thus further RCT was necessary (13).

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
pink esthetic score
Time Frame: should be measured after 8 months below implant and graft placement
|
evaluation of pink esthetic score around immediate implant only in esthetic zone around immediate implant with connective tissue graft in esthetic zone
|
should be measured after 8 months below implant and graft placement
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
tissue piotype
Time Frame: should be measured after 6 months below implant and graft placement
|
It is measured by penetrating the gingiva perpendicular to the tooth with the periodontal probe down to the bone after giving local anesthesia to determine the thickness of the tissue and apical to the gingival margin at the vertical bisecting midline with reference to the cementoenamel junction of adjacent teeth.
|
should be measured after 6 months below implant and graft placement
|
width of keratinized gingiva
Time Frame: should be measured after 6 months below implant and graft placement
|
It is recorded as the distance from the mucogingival junction (MGJ) to the free gingival margin of the related tooth by graduated periodontal probe.
|
should be measured after 6 months below implant and graft placement
