Dimensional changes in free gingival grafts: scalpel versus Er:YAG laser—a preliminary study
Lasers in Medical Science, 2015Co-Authors: Çiğdem Coşkun Türer, Hanifi Ipek, Tuğrul Kirtiloğlu, Gökhan AçikgözAbstract:The aim of this clinical study was to compare dimensional changes of the transplanted grafts when the recipient area was prepared with either erbium:yttrium, aluminum, and garnet (Er:YAG) laser or scalpel in free gingival grafts (FGGs). In the first and second groups of ten patients, the recipient area was prepared with an Er:YAG laser and a scalpel, respectively. All grafts were harvested from the palate at standard dimensions (horizontal, 14 mm; vertical, 8 mm). Probing depth, clinical attachment level, and keratinized tissue width were measured before surgery. FGG dimensions (width, length, and area) were measured using the University of North Carolina-15 manual probe (N15) (Nordent Manufacturing, Inc., IL, USA) during surgery and at 10, 21, and 90 days postoperatively. Differences between the two groups were statistically analyzed. In both groups, there was a statistically significant reduction in vertical and horizontal dimensions ( p

The Er:YAG laser may be used with similar effectiveness as the scalpel in the preparation of the recipient site for free gingival grafts.

long term outcomes after vestibuloplasty with a porcine collagen matrix mucograft versus the free gingival graft a comparative prospective clinical trial
Clinical Oral Implants Research, 2016Co-Authors: Christian Schmitt, Falk Wehrhan, Tobias Moest, Rainer Lutz, Friedrich Wilhelm Neukam, Karl Andreas SchlegelAbstract:Objectives Porcine collagen matrices are proclaimed being a sufficient alternative to autologous free gingival grafts (FGG) in terms of augmenting the keratinized mucosa. The collagen matrix Mucograft® (CM) already showed a comparable clinical performance in the early healing phase, similar histological appearance, and even a more natural appearance of augmented regions. Predictability for long-term stability does not yet exist due to missing studies reporting of a follow-up >6 months. Material and methods The study included 48 patients with atrophic edentulous or partially edentulous lower jaw situations that had undergone an implant treatment. In the context of implant exposure, a vestibuloplasty was either performed with two FGGs from the palate (n = 21 patients) or with the CM (n = 27 patients). Surgery time was recorded from the first incision to the last suture. Follow-up examinations were performed at the following time points: 10, 30, 90, and 180 days and 1, 2, 3, 4, and 5 years after surgery. The width of keratinized mucosa was measured at the buccal aspect of each implant, and augmented sites were evaluated in terms of their clinical appearances (texture and color). Results The groups showed similar healing with increased peri-implant keratinized mucosa after surgery (FGG: 13.06 mm ± 2.26 mm and CM: 12.96 mm ± 2.86 mm). The maximum follow-up was 5 years (5 patients per group). After 180 days, the width of keratinized mucosa had decreased to 67.08 ± 13.85% in the FGG group and 58.88 ± 14.62% in the CM group with no statistically significant difference. The total loss of the width of keratinized mucosa after 5 years was significant between the FGG (40.65%) and the CM group (52.89%). The CM group had significantly shorter operation times than the FGG group. Augmented soft tissues had a comparable clinical appearance to adjacent native gingiva in the CM group. FGGs could still be defined after 5 years. Conclusions The FGG and the CM are both suitable for the regeneration of the peri-implant keratinized mucosa with a sufficient long-term stability. With the CM, tissue harvesting procedures are invalid, surgery time can be reduced, and regenerated tissues have a more esthetic appearance.

vestibuloplasty porcine collagen matrix versus free gingival graft a clinical and histologic study
Journal of Periodontology, 2013Co-Authors: Christian Tudor, Katrin Kiener, Stefan Eitner, Abbas Agaimy, Falk Wehrhan, Christian Schmitt, Johannes Schmitt, Karl Andreas SchlegelAbstract:Background: A free gingival graft (FGG) is currently the gold standard for augmenting small areas of keratinized mucosa. The porcine collagen matrix (CM) represents an alternative to autologous tissue harvesting. This study aims to compare the CM versus FGGs for augmenting keratinized peri-implant mucosa based on clinical and histologic evaluations.Methods: The study included 14 patients who underwent a vestibuloplasty with either a FGG from the palate (n = 7) or the CM (n = 7). An implant-fixed vestibular retention splint was inserted for 30 days. Follow-up examinations were performed at 4, 10, 30, and 90 days after surgery. Width of keratinized mucosa was measured in the region of each implant (days 10, 30, and 90). After 90 days, a biopsy was harvested for histologic and immunohistologic analyses. To characterize newly formed soft tissue, the authors stained for tissue-and differentiation-specific markers, cytokeratin (CK) 5/6, 13, and 14, to detect presence or absence of keratinization.Results: The gr...

free gingival grafts graft shrinkage and donor site healing in smokers and non smokers
Web Science, 2010Co-Authors: Cleverson O Silva, Erica Del Peloso Ribeiro, Antonio Wilson Sallum, Dimitris N TatakisAbstract:Background: This prospective clinical study aims to evaluate the influence of cigarette smoking on free gingival graft (FGG) healing, by assessing FGG dimensional changes and donor-site wound healing. Methods: Twelve non-smokers and 10 smokers treatment planned for FGG to augment keratinized tissue dimensions in the mandibular incisor area completed the study. All subjects received standardized FGG of same dimensions. Probing depth, gingival margin position, clinical attachment level, keratinized tissue (KT) width, gingival thickness, and FGG dimensions (width, length, and area) were assessed and recorded before surgery, and 7, 15, 30, 60, and 90 days postoperatively. The palatal donor area was evaluated for immediate bleeding and complete wound epithelialization. Differences between the two groups (smokers and non-smokers) were statistically analyzed. Results: FGG dimensions changed significantly postoperatively. At 90 days postoperatively, FGG width, length, and area were respectively reduced by 31%, 22%, and 44% in nonsmokers and by 44%, 25%, and 58% in smokers (no significant differences between groups; P >0.05). Significant KT increases were observed in both non-smokers and smokers (5.4 and 4.8 mm, respectively). Donor-site immediate bleeding was significantly more prevalent in non-smokers (75%) compared to smokers (30%) (P = 0.04). At 15 days postoperatively, donorsite complete epithelialization was much more prevalent in non-smokers (92%) than in smokers (20%) (P <0.002). Conclusion: Smoking alters FGG donor-site wound healing by reducing immediate bleeding incidence and by delaying epithelialization, although it does not have discernible effects on postoperative FGG dimensional changes.

patient outcomes following subepithelial connective tissue graft and free gingival graft procedures
Journal of Periodontology, 2008Co-Authors: Jeffrey R Wessel, Dimitris N TatakisAbstract:Background: Subepithelial connective tissue grafts (CTGs) and free gingival grafts (FGGs) are common periodontal procedures with similar indications; however, they may differ regarding patient outcomes. Reports on postoperative periodontal patient outcomes are limited. The aim of this observational trial was to compare patient-based outcomes for CTGs and FGGs.Methods: Patients who received CTG or FGG completed postoperative questionnaires at 3 days and 3 weeks to assess pain, number of analgesic pills taken, and number of days pills were taken. Postoperative pain was assessed using a visual analog scale (VAS).Results: Twenty-three subjects (12 CTGs and 11 FGGs) completed the study. Differences between CTG and FGG groups in VAS pain scores at 3 days did not reach statistical significance. The proportion of subjects reporting pain in the palate at 3 days was significantly greater for FGG (P <0.05). There were no significant intergroup differences at 3 weeks. For the FGG group, 3-week VAS pain scores were le...
