Brief Summary

Soft tissue defects can be a problem, especially in patients with high smile lines; in these clinical scenarios, the treatment with periodontal plastic surgery in combination with the use of a connective tissue graft (CTG) is considered the gold-standard procedure. Single incision technique (Huerzeler \& Weng, 1999) is one of the suggested procedures to harvest the CTG from palate. The UPV/EHU technique (Aguirre-Zorzano et al, 2017) showed less inflammation and post-surgical complications than trap-door technique, but also other technique should to be analysed. However, there is still no consensus about which is the best technique to obtain this kind of graft. Therefore, clinicians should justify their choice based on the tissue's quality obtained and the patient's well-being, producing the least number of complications, such as inflammation, post-surgical pain, or recession in the donor area. HYPOTHESIS: Does the technique of obtaining an CTG of the palate using the "UPV/EHU technique" (Aguirre-Zorzano et al., 2017) result in a lower number of complications versus the "single incision technique" (Huerzeler \& Weng, 1999)? OBJECTIVES The main objective is to assess whether the complications occurring with the harvesting of the CTG using the "UPV/EHU technique" (Aguirre-Zorzano et al., 2017) are lower than with the "single incision technique"(Huerzeler \& Weng, 1999), knowing the patient's perception of pain. The secondary objectives are: a) necrosis of the palate, b) possible resulting recession in the donor area, and c) characteristics of the graft obtained

Outcome Measures

Primary Outcomes (1)

  • Post-surgical pain perception

    The subject will we instructed to collect their perception of post-surgical pain in the VAS based on the UPV/EHU Pain diary (Fernandez-Jimenez et al, 2021). Specifically the subject will record: Its intensity (0-100mm), its duration (minutes or hours) and if any analgesic treatment has been necessary (No o Yes: Which?).

    After surgery up to 14 days

Secondary Outcomes (13)

  • Central Sensitization Inventory severity-level score of the subject Central Sensitization inventory (CSI) (Mayer et al. 2012)

    Baseline

  • Pre-surgical pain perception.

    Baseline

  • Necrosis of the palate

    up to 7 days post-srugery

  • Gingival recession (REC) in donor area

    Change from baseline at following surgery sixth month respectively.

  • Post-surgical complications

    After surgery first seven days.

  • +8 more secondary outcomes

Study Arms (2)

UPV/EHU technique (Aguirre-Zorzano et al 2017)

EXPERIMENTAL

Harvesting a connective tissue graft from palate by the UPV/EHU technique.

Procedure: UPV/EHU technique (Aguirre-Zorzano et al 2017)

Single incision technique (Huerzeler & Weng 1999)

ACTIVE COMPARATOR

Harvesting a connective tissue graft from palate by the single incision technique

Procedure: Single incision technique (Huerzeler & Weng 1999)

Interventions

The "UPV/EHU technique" (Aguirre-Zorzano et al., 2017) begins with the elevation of the full thickness flap (FTF) in the palate and an intrasulcular incision performed with a number 12 blade, preserving the papillae in the interproximal spaces. Then, the FTF is dissected with a 15c blade, holding the flap with tissue forceps, leaving the epithelium and a thin layer of the connective tissue in the flap, so that the underlying connective tissue can be harvested. After that the flap is sutured.

UPV/EHU technique (Aguirre-Zorzano et al 2017)

The CTG is harvested with the single incsion technique described by Huerzeler \& Weng in 1999.
