Plain English summary of protocol

Background and study aims
Several esthetic (cosmetic) complications are associated with insufficient gingival (gum) tissue around dental implants. The aim of this study is to compare the effect of two different grafts, one derived from the palate and the other from the patient's blood, on the improvement of gum tissue thickness around dental implants.

Who can participate?
Patients aged 21 years old or above with two missing teeth with thin gingival (gum) tissue

What does the study involve?
During dental implant placement for each participant one site is treated with a graft derived from the palate and the other with a graft from the patient's blood.

What are the possible benefits and risks of participating?
Participants may benefit from having their missing teeth replaced with esthetically enhanced, implant-supported restorations. The risks include implant failure.

Where is the study run from?
Mansoura University (Egypt)

When is the study starting and how long is it expected to run for?
September 2016 to September 2020

Who is funding the study?

Scientific titleComparison of platelet-rich fibrin and sub-epithelial connective tissue graft in managing thin gingival biotype surrounding acid-etched titanium implants
Study objectivesPlatelet-rich fibrin (PRF) could be an effective alternative to sub-epithelial connective tissue graft (SCTG) in the augmentation of the peri-implant soft tissue thickness
Ethics approval(s)Approved 17/09/2016, Mansoura University Ethics board (Faculty of Dentistry, Mansoura University, Mansoura, Egypt 35516; +20 (0)1004763722; melewa@mans.edu.eg), ref: not applicable
Health condition(s) or problem(s) studiedPeri-implant soft tissue repair
InterventionThe present study was a split-mouth controlled clinical trial.

For each study participant, one site was treated with SCTG while the other was treated with PRF membrane during dental implant placement.

Treatment outcomes included the assessment of the facial gingival thickness using cone-beam computed tomography (CBCT) at the baseline (T0) and 6 months postoperatively (T1), and the Pink esthetic score (PES) at T1 and 3 months later after prosthesis placement (T2).

Secondary outcome measuresEsthetic improvement measured using the Pink esthetic score (PES) at T1 and 3 months later after prosthesis placement (T2)
