Patient and Operator Centered Outcomes Concerning Connective Tissue Graft Should Be Considered to Choose Adequately Which Protocol to Use

50 sites will be included. All investigations will be carried out in accordance with the 1975 Helsinki Declaration, as revised in 2013 for ethical approval. All participants will provide written informed consent after receiving explanations on study objectives and procedures. Primary outcomes will be patient- and operator-centered outcomes. Patient- and operator-centered outcomes will be assessed through visual analogue scale (VAS), questionnaires containing self-developed questions about each phase of the treatment which will be administered at the end of each phase. The questionnaires will be administered as part of a survey which aimed to obtain information about the dental practices. Secondary outcomes will be time-efficiency by assessing workflow duration and number of appointments needed to complete the procedure. The treatment phases will include digital analysis of landmarks and design, of the guide and surgical phase (free gingival graft harvesting ). Time will be recorded in minutes. All the parameters will be recorded in the clinical chart by the same two operators not involved in the treatment after each phase was completed. The planned duration for the research will be 6 months.
