Brief summary

This study aims to evaluate the effects of autogenous grafts harvested from different palatal regions on the peri-implant mucosa when applied during second-stage dental implant surgery. Clinical, radiographic, and digital assessment methods will be used to investigate the early effects of these grafts on peri-implant mucosal width and thickness. In addition, peri-implant tissue health and patient-reported outcomes will be evaluated to compare the effectiveness of the grafting techniques in peri-implant soft tissue management.

Interventions

PROCEDURECoronal palatal tissue

This group will receive palatal grafts including marginal and interdental gingiva. This coronal palatal tissue will be applied to the peri-implant tissue at the second-stage implant surgery.

PROCEDUREApical palatal tissue

This group will receive palatal grafts harvested from approximately 1.5 mm apical to the gingival margin. This graft will be applied to the peri-implant tissue at the second-stage implant surgery.

Design outcomes

Primary

MeasureTime frameDescription
Peri-implant Mucosal ThicknessPre-operative and post-operative (before implant placement, 3rd month (second-stage implant surgery), 6th month after implant placement, and 12th month after prosthetic loading)The primary outcome is the change in peri-implant mucosal thickness measured at four time points using clinical and digital methods.

Secondary

MeasureTime frameDescription
Keratinized Mucosa WidthPre-operative and post-operative (before implant placement, 3rd month (second-stage implant surgery), 6th month after implant placement, and 12th month after prosthetic loading)Keratinized tissue width will be measured from the mid-buccal aspect of the edentulous area.
Vestibular DepthPre-operative and post-operative (before implant placement, 3rd month (second-stage implant surgery), 6th month after implant placement, and 12th month after prosthetic loading)Vestibular depth is defined as the vertical distance between the midcrestal area and the point of greatest concavity of the mucosal fold.
Modified Plaque IndexPostoperative 6th month after implant placement and 12th month after prosthetic loadingModified plaque index will be measured at six points around each implant by an index with a minimum value of 0 and a maximum of 3.
Modified Bleeding IndexPostoperative 6th month after implant placement and 12th month after prosthetic loadingModified bleeding index will be measured at six points around each implant by an index with a minimum value of 0 and a maximum of 3.
Peri- implant Probing DepthPostoperative 6th month after implant placement and 12th month after prosthetic loadingPeri-implant probing depth will be measured at six points around each implant.
Mucosal Recession12th month after prosthetic loadingMucosal recession will be measured as the distance between the implant abutment interface and the mucosal margin.
Marginal Bone LevelPre-operative and post-operative (before implant placement, 3rd month (second-stage implant surgery), 6th month after implant placement, and 12th month after prosthetic loading)Marginal bone level will be measured on periapical radiographs taken by the parallel technique.
Pink Esthetic Score (PES)Postoperative 3rd month (second-stage implant surgery) and 12th month after prosthetic loadingPeri-implant soft tissue esthetics will be evaluated using the Pink Esthetic Score with a minimum value of 0 and a maximum of 14.
Postoperative Pain AssessmentPostoperative 14 days (daily after graft application)Postoperative pain as patient-reported outcome will be recorded using a visual analog scale (VAS; 0-100).
Analgesic ConsumptionPostoperative 14.days (after graft application)The amount of analgesic medication used (mg) will be recorded.
Patient SatisfactionPostoperative 14.days (after graft application)Patient satisfaction with the surgical procedure will be assessed using a three-point Likert scale (0 = no, 1 = maybe, 2 = yes).
Patient-Perceived Esthetic Outcome12th month after prosthetic loadingPatient perception of peri-implant soft tissue esthetics will be evaluated using a visual analog scale (VAS; 0-100).
Oral Health-Related Quality of LifePostoperative 3rd month (second-stage implant surgery) and 12th month after prosthetic loadingOral health-related quality of life will be assessed using the Oral Health Impact Profile (OHIP-14) questionnaire.
