Traditionally, autogenous grafts harvested from the palate are fixated to the recipient site utilizing a wide array of suturing techniques. In this paper a simplified sutureless method to free gingival grafting was demonstrated utilizing medical grade tissue adhesive, and Coe-Pak as a way to avoid sutures entirely, making the procedure simpler and faster to perform saving valuable chairside time for the clinician and patient. 111 consecutive patients in private practice were included in this case series. In all cases, free gingival grafts harvested from the palate were fixated to the recipient site utilizing medical grade cyanoacrylate and periodontal dressing alone after hydrating the grafts in liquid platelet-rich fibrin (liquid-PRF). The amount of keratinized tissue, recession, and attached tissue were recorded prior to treatment and at their follow-up. All clinical cases demonstrated successful graft integration with uneventful healing despite zero sutures being utilized. In 111 cases, a total of 348 teeth were grafted with an average gain of 3.98 + 2.36mm of keratinized tissue, 3.48 + 1.21mm of attached tissue, and a 0.15 + 0.54mm reduction in recession, with no failures. The simplified sutureless free gingival grafting technique is a predictable method to rapidly and confidently secure free gingival grafts around teeth and implants to increase the amount of keratinized and attached tissue. Further randomized comparative studies are necessary, specifically investigating the effects of liquid-PRF at the recipient site.","PeriodicalId":54948,"journal":{"name":"International Journal of Periodontics & Restorative Dentistry","volume":"0 0","pages":"1-25"},"PeriodicalIF":1.3,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144175987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A step-by-step illustrated guide provides surgeons a practical roadmap for the seamless execution of the HOT technique (short for 'Harvesting Oblique Tuberosity'), which is further divided into HOT 1 (regular shape) and HOT 2 (extended shape), depending on the required graft length. By breaking the overall procedure into clearly defined steps, the technique enhances both the predictability and reproducibility of graft outcomes. Additionally, this case series underscores the clinical versatility of the tuberosity replacement graft.

Standardized intraoral photographs were obtained to determine keratinized tissue width (KTW), presence of GS in all facial and interproximal areas between the maxillary canines, and other variables of interest, such as gingival architecture (GA), tooth shape, and location.

Greater mean GT, BT, and KTW values were observed in facial areas that exhibited GS. Interdental GS was present in 73% of the sites, and it was more frequently observed in men, in the central incisor region, and when facial GS was present. Multilevel logistic regression revealed a statistically significant association between the presence of GS and KTW, BT measured at 3 mm apical to the bone crest, and tooth type.

All treated sites healed uneventfully, and no complications were noted throughout the study. At 6 months, a statistically significant reduction in recession was noted at the treated sites, exhibiting an overall mRC of 89.14% ± 19.15% and a CRC of 72.7%.

Enamel matrix derivative (EMD) may improve and accelerate soft tissue wound healing and inflammatory resolution.

A resective surgical approach with an adjunctive modified implantoplasty refers to the modification of the implant body into a constricted area to mimic a 'waist' silhouette. This modified technique forms an adequate concave smooth area that may favor the outcomes of resective surgical therapy for soft tissue adaptation, biofilm control, and possible peri-implant bone gain over the long term. The present case series aimed to exhibit the long-term clinical and radiographic outcomes of resective surgery with adjunctive implantoplasty over a 6- to 11-year follow-up. Four patients presenting four implants (one per patient) diagnosed with peri-implantitis (according to an established case definition) were included in the present case series. Patients underwent resective surgery, a modified implantoplasty approach, and implant surface decontamination. After surgical therapy, clinical and radiographic outcomes such as bleeding on probing (BoP), suppuration on probing (SoP), probing depth (PD), marginal recession (MR), modified plaque index (mPI), and marginal bone levels (MBLs) were recorded over a long-term follow-up period.
