About this study
Official title: Patient-reported Outcomes of Donor Site Healing Using Different Palatal Protection Techniques: a Randomized Controlled Clinical Trial
This study has been initiated to evaluate the question, "What is the best way to protect the palate after a gum graft is removed?" The overall objective is to determine if there is a difference in PROMs of donor site healing using different palatal post-operative protection techniques.
Read the detailed description
This study aims to determine if there is a difference in subject-reported outcome measures (PROMs) when different palatal post-operative protection techniques are used during healing after an autogenous soft-tissue graft is harvested from the palate for periodontal and peri-implant plastic surgery. The secondary objective is to evaluate if there is a difference in the healing of the palatal tissue via photographic and 3D linear and volumetric changes analysis after using the different protective techniques. Furthermore, the study will evaluate the time needed for fabrication and intraoral adjustment of each protective barrier and professional preference among the techniques utilized.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Visual Analog scale (VAS) questionnaireOther
A Visual Analog Scale (VAS) questionnaire is a type of self-report tool where respondents mark a point on a continuous line to indicate the intensity of a subjective experience, like pain, fatigue, or happiness, between two extreme anchor points (e.g., "no pain" at one end and "worst possible pain" at the other), allowing for a more nuanced response compared to a standard Likert scale; essentially, it measures the degree of a symptom along a visual continuum.
Vacuum-formed retainer (VFR) techniqueOther
On the day of surgery, the stent will be positioned to cover the palate and the anterior and posterior teeth, including their occlusal and buccal surfaces bilaterally, to provide retention. Vacuum-formed retainers are a common clinical practice used after harvesting a palatal graft, in order to provide a mechanical barrier to reduce post-operative pain.
3-D printed acrylic resin stent (3DS) techniqueOther
On the day of surgery, the previously made palatal stent (3DS) will be placed in position and stabilized by mechanical retention in the palate and palatal surface of the maxillary teeth, bilaterally.
Flowable resin composite stent (FRC) techniqueOther
On the day of surgery, a layer of flowable composite will be added, covering all the wound dimensions, restricted to the wound (no extension to the adjacent teeth). Flowable composite has been shown to help reduce pain using the same principal of providing a mechanical barrier to protect the palatal wound from the oral cavity
Photographs of the patient's palateOther
At the 14-day, 30-day and 3-month follow-up visits, photographs of the patient's palate (Canon EOS 60D DSLR, Canon, USA) will be taken for healing evaluation as well as intraoral scans (TRIOS 4, 3Shape) of the palatal wound for linear and volumetric changes analysis.
Measuring graft dimensionsOther
The graft dimensions will be measured with the use of a periodontal probe and recorded on the data collection form. The professional preference in regard to technique applied and the time spent by the surgeon to adjust the stent intraorally will also be recorded in the same form.
Chairside Polymer StentOther
The stent will be placed directly in the roof of the mouth. Instructions will be provided to the patient about how to remove, place and clean the stent. The patients will be instructed to wear the stent for the first 3 days and per their personal preference on the 4th day and after.
| Study group | Role | What they receive |
|---|---|---|
| Vacuum-formed retainer (VFR): plastic device | Experimental | Subjects will have both dental arches scanned using an intraoral optical scanner to generate the digital model of the jaw.. A resin model will be 3D printed generating the physical model. A palatal stent will be made out of thermoforming plastic in the model using a vacuum, The stent will cover the palate and the anterior and posterior teeth, including their occlusal and buccal surfaces bilaterally, to provide retention. On the day of the surgery, at the final stage of the surgical procedure (after the graft placement and suture of the recipient site), a collagen sponge will be positioned in the palatal wound, and non-resorbable sutures will be placed above the sponge. The previously made plastic palatal stent (VFR) will be placed in position and stabilized by mechanical retention using the palate and maxillary teeth, bilaterally. The subjects will be instructed to wear the stent uninterruptedly in the first 3 days and per their preference on the 4th day and after. Receives: Other: Visual Analog scale (VAS) questionnaire; Other: Vacuum-formed retainer (VFR) technique; Other: Photographs of the patient's palate; Other: Measuring graft dimensions |
| 3-D printed acrylic resin stent (3DS): digitally designed | Experimental | Subjects will have both dental arches scanned using an intraoral optical scanner to generate the digital model file of the patient's jaws. A palatal stent will be digitally designed. The stent will cover the palatal area to the maximum extent, respecting the limit between the hard and soft palate to avoid any discomfort or gag reflex by the subjects. At the final stage of the surgical procedure (after the graft placement and suture of the recipient site), a collagen sponge will be positioned in the palatal wound, and non-resorbable sutures will be placed above the sponge. The previously made palatal stent (3DS) will be placed in position and stabilized by mechanical retention in the palate and palatal surface of the maxillary teeth, bilaterally. Receives: Other: Visual Analog scale (VAS) questionnaire; Other: 3-D printed acrylic resin stent (3DS) technique; Other: Photographs of the patient's palate; Other: Measuring graft dimensions |
| Flowable resin composite stent (FRC): mechanical barrier | Experimental | After the placement of the graft and the suture of the recipient site, a collagen sponge will be positioned in the palatal wound. Then, a layer of cyanoacrylate (PeriAcryl 90HV, GluStitch) will be placed above the sponge using a microbrush. Non-resorbable sutures will be placed covering the palatal dressing, with the suture knots facing the buccal surfaces of the maxillary posterior teeth. Finally, a layer of flowable composite will be added, covering all the wound dimensions, restricted to the wound (no extension to the adjacent teeth). Flowable composite has been shown to help reduce pain using the same principal of providing a mechanical barrier to protect the palatal wound from the oral cavity. Subjects will have both dental arches scanned using an intraoral optical scanner to generate the digital model for secondary analysis. Receives: Other: Visual Analog scale (VAS) questionnaire; Other: Flowable resin composite stent (FRC) technique; Other: Photographs of the patient's palate; Other: Measuring graft dimensions |
| Chairside Polymer Stent:CPS: mechanical barrier | Experimental | During the preoperative appoint, both dental arches scanned using an intraoral optical scanner scanner (TRIOS, 3Shape) to generate the digital model in .STL file of the patient's jaws. In this group, the .STL files of the digital models of patient's jaws are not necessary for the fabrication of the stent but will be stored for future analysis of secondary outcomes of the research that includes the healing of the palatal wound via volumetric and linear changes analysis. Before the graft has been harvested, 4 cubes of Zn-containing granules are placed into a warm water bath and manipulated into a 2mm disk and placed in the patient's mouth to be formed to fit the patient. After the graft has been harvested, the stent will be placed directly in the roof of the mouth. Instructions will be provided to the patient about how to remove, place and clean the stent. The patients will be instructed to wear the stent for the first 3 days and per their personal preference on the 4th day and after. Receives: Other: Visual Analog scale (VAS) questionnaire; Other: Photographs of the patient's palate; Other: Measuring graft dimensions; Other: Chairside Polymer Stent |
What is being measured
The primary outcome is the main question the study is designed to answer.
Evaluate postoperative pain level after autogenous gingival graft comparing 3 different palatal dressing designs
Evaluate postoperative pain level by documenting the number of pain pills taken during the initial two weeks of the healing process.
Measured: Up to 2 weeks post-operatively
Evaluate swelling and bleeding perception after autogenous gingival graft comparing 3 different palatal dressing designs
Using a Visual Analog scale (VAS) questionnaire indicating the subject's perception of swelling and bleeding following the graft. The VAS is a type of self-report tool where subjects mark a point on a continuous line to indicate the intensity of a subjective experience between two extreme anchor points (e.g., "no pain" at one end and "worst possible pain" at the other), allowing for a more nuanced response compared to a standard Likert scale. Essentially, it measures the degree of a symptom along a visual continuum.
Measured: 2 weeks, 1 month and 3 months post-operative
Evaluate the willingness to retreat by the subjects after autogenous gingival graft comparing 3 different palatal dressing designs
Using a Visual Analog scale (VAS) questionnaire indicating the subject's willingness to retreat following the graft. The VAS is a type of self-report tool where subjects mark a point on a continuous line to indicate the intensity of a subjective experience between two extreme anchor points (e.g., "no pain" at one end and "worst possible pain" at the other), allowing for a more nuanced response compared to a standard Likert scale. Essentially, it measures the degree of a symptom along a visual continuum.
Measured: 2 weeks, 1 month and 3 months post-operative
