Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This randomized controlled trial compares MTUN and TCAF to determine which technique provides better root coverage for receding gums at single recession in the premandible. The main question it aims to answer is:
\- What is the average root coverage achieved with each technique in the short and long term? This may be clinically relevant because covering gum recession can reduce tooth sensitivity, improve aesthetics and make oral hygiene easier.
Researchers will compare the modified tunnel technique (MTUN = the gum is undermined) with the tunneled coronally advanced flap (TCAF = the gum is undermined, only partially detached and repositioned higher). In both techniques, a small piece of tissue is removed from the palate, which is used to cover the recession. The purpose of the connective tissue graft under the flap/tunnel, is to increase thickness and provide support. Pain associated to the material used to cover the donorsite will be seen as the secondary research question. The site will either be covered by spongostan and multiple stitches or a palatal stent.
Participants will:
* Undergo surgery (MTUN or TCAF, randomly assigned) to cover recessions
* Attend regular check-ups for up to 10 years after surgery
* Keep a postoperative journal (recording medication use, pain levels, tooth sensitivity, etc.)

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
TCAF + CTG
Tunneled coronally advanced flap with a connective tissue graft.
tunneled coronally advanced flap with connective tissue graft
The gum at the recession site is undermined, only partially detached and reattached higher (combined withh a connective tissue graft).
MTUN + CTG
Modified tunnel with connective tissue graft.
modified tunnel with connective tissue graft
At the recession site, the gingiva is undermined to create a tunnel, and a connective tissue graft is inserted through the sulcus into this space before advancing the flap coronally.
