Brief Summary
The goal of this study is to compare clinical and histologically the soft tissue changes in terms of volume gain and stability around dental implants in cases where a subepithelial connective tissue graft from the palate or from the tuberosity is used randomly

Outcome Measures
Primary Outcomes (2)
Soft tissue volume gain
Following soft tissue augmentation procedure volume gain is registered using intraoral optical scan. Superposition between three dimensional images from baseline (before augmentation procedure) and 3 months postoperative is done.
Baseline to 3 months postoperative
Soft tissue stability
To evaluate soft tissue stability an intraoral optical scan is performed at 4 and 12 months postoperative. Also a superimposition between 4 months and 12 months optical images is done.
4 months postoperative to 12 months postoperative

Interventions
Recipient site: Intrasulcular incision at the buccal side of the implant extending in one adjacent tooth for each side and a partial-thickness mucosal flap raised. The connective tissue was secured with suture. Allocation to either treatment was performed according to a randomization table. Donor site A double-bladed scalpel handle 1,5mm was used in both areas to obtain the same thickness. Palate (CG) The double incision was made approximately 2 to 3 mm apical to the gingival margins of premolars. The donor tissue was removed and cross-mattress sutures were used to approximate the wound on the palate. In both groups the epithelial collar removed. Graft required dimensions for both groups:10mm height, 12mm length and 1,5mm thick.

The connective tissue was secured with suture. Allocation to either treatment was performed according to a randomization table. Donor site A double-bladed scalpel handle 1,5mm was used in both areas to obtain the same thickness. Tuberosity (TG) The double incision was made from the distal of the terminal tooth. A second incision was made perpendicular to the linear incision at a distal point, which joined the two linear incisions. The graft was removed and a crossed horizontal suspension suture was used. Epithelial collar removed. Graft required dimensions for both groups:10mm height, 12mm length and 1,5mm thick.
Intraoral optical scan was performed at both groups at baseline, 3 months, 4 months and 12 months to be able to compare volumetric changes.
Eligibility Criteria
You may qualify if:
- Patient must be ≥18 years and able to understand the nature of the proposed surgery and to a signed informed consent.
- Implant must be located between 2 fixed reference points i.e. clinical crowns.
- All implants locations with a need of a soft tissue volume augmentation.
- Palate must have ≥2mm of thickness at premolar area.
- Tuberosity \> 12mm in length.
- Full mouth plaque and bleeding score \<20%.
You may not qualify if:
- Previous soft tissue augmentation in the area.
- Heavy Smokers (\> 10 cigarettes per day).
- Local or systemic conditions that would interfere with routine periodontal therapy (non controlled diabetes, liver function disorder, immunosuppressant disease, autoimmune disease).
- Allergy to Non-Steroidal Anti-Inflammatory Drugs.
- Patients taking medications that cause gingival enlargement
- Gingival idiopatic overgrowth
