Free Gingival Graft and acellular dermal matrix for Gingival augmentation: a 15-year clinical study
Clinical Oral Investigations, 2020Co-Authors: Cecilia Amparo Reyes Cevallos, Daniel Romeu Benchimol Resende, Carla Andreotti Damante, Adriana Campos Passanezi Sant’ana, Maria Lúcia Rubo Rezende, Sebastião Luiz Aguiar Greghi, Mariana Schutzer Ragghianti ZangrandoAbstract:Objectives This study evaluated clinical outcomes of acellular dermal matrix (ADM) alloGraft compared with autogenous free Gingival Graft (FGG) for Gingival augmentation after 15 years. Material and methods Twenty-two patients were originally included and evaluated by de Resende et al. (Clin Oral Investig 23:539–550, 2019), and 12 accepted to participate in this longitudinal evaluation. Clinical parameters evaluated were recession depth (RD), probing depth (PD), clinical attachment level (CAL), keratinized tissue width (KTW), and soft tissue thickness (TT).

In addition, esthetic perception was evaluated by patients and by a calibrated periodontist. Data were evaluated by ANOVA complemented by Tukey tests (p < 0.05). After 15 years, both treatments provided a significant increase in KTW and TT but with superior results for the FGG group (p < 0.05). No differences were observed between groups for PD and CAL. In the ADM group, RD significantly increased in long term, as well as the rate of tissue contraction. The percentage of shrinkage for the ADM group was 59.6%. Conversely, the FGG group presented a creeping attachment of 17.6% and RD significantly decreased in long term. The ADM group presented superior results considering professional esthetic perception. Both treatments longitudinally promoted significant gain of keratinized tissue width and thickness with superior outcomes for the FGG group. The ADM group demonstrated more tissue contraction and Gingival recession whereas the FGG group presented creeping attachment. Professional esthetic perception was superior for the ADM group. This study added important clinical data with long-term evaluation of ADM compared with FGG.

acellular dermal matrix alloGraft versus free Gingival Graft a histological evaluation and split mouth randomized clinical trial
Clinical Oral Investigations, 2019Co-Authors: Daniel Romeu Benchimol Resende, Carla Andreotti Damante, Sebastião Luiz Aguiar Greghi, Aline Franco Siqueira, César Augusto Magalhães Benfatti, Mariana Schutzer Ragghianti ZangrandoAbstract:OBJECTIVES: This split-mouth controlled randomized clinical trial evaluated clinical and histological results of acellular dermal matrix alloGraft (ADM) compared to autogenous free Gingival Graft (FGG) for keratinized tissue augmentation. MATERIAL AND METHODS: Twenty-five patients with the absence or deficiency of keratinized tissue (50 sites) were treated with FGG (control group) and ADM (test group). Clinical parameters included keratinized tissue width (KTW) (primary outcome), soft tissue thickness (TT), recession depth (RD), probing depth (PD), and clinical attachment level (CAL). Esthetic perception was evaluated by patients and by a calibrated periodontist using visual analog scale (VAS). Histological analysis included biopsies of five different patients from both test and control sites for each evaluation period (n = 25). The analysis included percentage of connective tissue components, epithelial luminal to basal surface ratio, tissue maturation, and presence of elastic fibers. Data were evaluated by ANOVA complemented by Tukey's tests (p < 0.05). RESULTS: After 6 months, PD and CAL demonstrated no differences between groups. ADM presented higher RD compared to FGG in all periods. Mean tissue shrinkage for control and test groups was 12.41 versus 55.7%. TT was inferior for ADM group compared to FGG. Esthetics perception by professional evaluation showed superior results for ADM. Histomorphometric analysis demonstrated higher percentage of cellularity, blood vessels, and epithelial luminal to basal surface ratio for FGG group. ADM group presented higher percentage of collagen fibers and inflammatory infiltrate. CONCLUSIONS: Both treatments resulted in improvement of clinical parameters, except for RD. ADM group presented more tissue shrinkage and delayed healing, confirmed histologically, but superior professional esthetic perception. CLINICAL RELEVANCE: This study added important clinical and histological data to contribute in the decision-making process between indication of FGG or ADM.

Autogenous soft tissue Grafting for periodontal and peri-implant plastic surgical reconstruction.
Journal of Periodontology, 2019Co-Authors: Giovanni Zucchelli, Lorenzo Tavelli, Giulio Rasperini, Michael K. Mcguire, Hom-lay Wang, Stephen E Feinberg, William V. GiannobileAbstract:This state-of-the-art review presents the latest evidence and the current status of autogenous soft tissue Grafting for soft tissue augmentation and recession coverage at teeth and dental implant sites. The indications and predictability of the free Gingival Graft and connective tissue Graft (CTG) techniques are highlighted, together with their expected clinical and esthetic outcomes. CTGs can be harvested from the maxillary tuberosity or from palate with different approaches that can have an impact on Graft quality and patient morbidity. The influence of CTGs on soft tissue thickness and keratinized tissue width are also discussed.

comparison between subepithelial connective tissue Graft and de epithelialized Gingival Graft a systematic review and a meta analysis
Journal of the International Academy of Periodontology, 2019Co-Authors: Lorenzo Tavelli, Andrea Ravida, Mustafa Tattan, Hom-lay WangAbstract:AIM: Sup-epithelial connective tissue Graft (SCTG) and de-epithelialized Gingival Graft (DGG) approaches have been investigated with a focus on post-operative morbidity but not from a clinical outcome standpoint. The aim of this systematic review was to systematically investigate the literature for coronally advanced flaps (CAFs) combined with SCTG or DGG. MATERIALS AND METHODS: Electronic and hand searches were performed to identified randomized controlled trials (RCTs) investigating the treatment of Gingival recession (GRs) using CAF, with at least a 1-year of follow-up. The primary outcome was the mean root coverage (mRC), while the secondary outcomes included recession reduction (Rec Red), keratinized tissue (KT) gain, probing depth (PD) change, and clinical attachment level (CAL) gain. RESULTS: Ten RCTs with a total of 408 Gingival recessions were included. The meta-analysis demonstrated that CAF + DGG is associated with superior mRC, Rec Red, KT gain, PD reduction and CAL gain. The mRC for SCTG and DGG at 1-year was 89.3% and 94.0% respectively, while the mean difference of the other clinical parameters between the two approaches was within 1 mm in favor of the DGG group. CONCLUSIONS: Limited evidence is available when comparing the two techniques, however the usage of DGG may be considered as the preferred technique of choice for autologous CTG harvesting when incorporated with a CAF.

pain perception following epithelialized Gingival Graft harvesting a randomized clinical trial
Clinical Oral Investigations, 2019Co-Authors: Lorenzo Tavelli, Giulio Rasperini, Andrea Ravida, Muhammad H A Saleh, Bartosz Maska, Hom-lay WangAbstract:OBJECTIVES: The aim of this study was to compare the effects of a hemostatic collagen sponge and a collagen sponge sealed with a bio-adhesive material on the palatal donor sites with the purpose of minimizing postoperative pain after epithelialized Gingival Graft (EGG) harvesting. MATERIAL AND METHODS: The present study consisted of 44 EGGs harvested in 44 patients. In the control group, a hemostatic collagen sponge was applied over the palatal wound, while the test group was treated with additional cyanoacrylate. Patients were observed for 14 days, evaluating the pain level by using the visual analogic scale. The consumption of analgesic during the postoperative period, the willingness for retreatment and the characteristic of the Graft were also analyzed. RESULTS: Statistically significant differences in pain perception were found between test and control groups in each of the studied days (p < 0.01). Analgesic consumption was lower in the test group (p < 0.01). Graft width < 14 mm was found to be associated with lower discomfort (p < 0.01). CONCLUSIONS: Adding an additional layer of cyanoacrylate over a hemostatic collagen sponge on the palatal wound following EGG harvesting was found to be successful in minimizing the postoperative discomfort and the need for analgesics. CLINICAL RELEVANCE: Postoperative pain after palatal tissue harvesting can be successfully minimized if the donor site open wound is protected with an external layer of cyanoacrylate over a collagen sponge.
