ABSTRACT
Zimmermann-Laband Syndrome (ZLS; MIM 135500) is a rare genetic disorder with the main clinical manifestations of gingival fibromatosis and finger/toe nail hypoplasia. KCNH1 (potassium channel, voltage-gated, subfamily H, member-1), KCNN3 (potassium channel, voltage-gated, subfamily H, member-3) and ATP6V1B2 (ATPase H+ transporting V1 subunit B2) genes are considered causative genes for ZLS. However, there are limited reports about the diverse clinical presentation and genetic heterogeneity. Reporting more information on phenotype-genotype correlation and the treatment of ZLS is necessary. This case reported a 2-year-old patient with gingival enlargement that failure of eruption of the deciduous teeth and severe hypoplasia of nails. Based on a systemic examination and a review of the relevant literature, we made an initial clinical diagnosis of ZLS. A novel pathogenic variant in the KCNH1 gene was identified using whole-exome sequencing to substantiate our preliminary diagnosis. The histopathological results were consistent with gingival fibromatosis. Gingivectomy and gingivoplasty were performed under general anesthesia. After surgery, the gingival appearance improved significantly, and the masticatory function of the teeth was restored. After 2-year follow-up, the gingival showed slightly hyperplasia. Systemic examination and gene sequencing firstly contribute to provide information for an early diagnosis for ZLS, then timely removal of the hyperplastic gingival facilitates the establishment of a normal occlusal relationship and improves oral aesthetics.

Idiopathic gingival fibromatosis (IGF), a rare fibroproliferative disease of unknown etiology, affects gingival tissue and has substantial adverse effects on patients. Therefore, the pathogenesis of IGF requires more extensive and in-depth research. In this case, a patient with confirmed IGF underwent initial nonsurgical periodontal therapy and gingivectomy, and the prognosis was good. The patient had no loss of periodontal attachment but had a history of swelling and bleeding of the gingiva prior to fibrous enlargement, which prompted further investigation. We explored the patient's subgingival microbiome and found a high abundance of periodontal pathogens. Gingival tissue biopsy revealed abundant fibrous tissue containing multiple inflammatory cell infiltrates. These results suggest that gingival inflammation secondary to periodontal pathogens can contribute to IGF onset.

OBJECTIVE: To explore the feasibility of the usage of digital guides in combination with low- and high-power lasers for the treatment of excessive gingival display, also known as "gummy smile". CLINICAL CONSIDERATIONS: Excessive gingival display due to altered passive eruption can affect patient's perception of their own esthetics and consequently have an impact on self-confidence. Therefore, the management of this condition should offer a predictable and stable long-lasting solution. To attain these objectives, digital planning emerges as a tool in optimizing the outcomes of crown lengthening surgery for this condition by enhancing precision through the use of surgical guides. Additionally, the usage of high- and low-powered lasers can provide a safe approach because of their tissue selective removal properties. CONCLUSIONS: The technique described showed satisfactory clinical results in the short- and long-term follow-up, leading to an improvement in patients' self-esteem. This approach integrates digital and laser technologies to deliver a surgical treatment characterized by precision, efficiency, and safety. CLINICAL SIGNIFICANCE: Digital dentistry has contributed to innovative dental procedures, as personalizing surgical guides for patients, assisting and guiding incisions of the gingival margins, as well as the extension of the osteotomy, during the procedures for increasing the clinical crown. Furthermore, smile esthetics are directly related to an individual's improved emotional and social quality of life.

INTRODUCTION: The case report presents a new possibility of treatment for a gummy smile in a patient with multiple etiologies, such as altered passive eruption and hypermobility upper lip. At first, crown lengthening was not sufficient to achieve the desired aesthetic result, being necessary its combination with lip repositioning. CASE PRESENTATION: Crown lengthening surgery (CLS) was performed in a 20-year-old woman, with a gingival display of 7.5 mm, having her gingival exposure reduced to 5.5 mm. Because the patient continued unsatisfied after 6 months, a new procedure was adopted. To reduce even more her gingival exposure, lip repositioning technique was performed associated with myotomy and the insertion of polyester threads as a physical barrier to prevent relapse. CONCLUSION: The result of the gingival display was reduced to 2.5 mm, removing the condition of a gummy smile after the combination of both techniques: crown lengthening, and lip repositioning. KEY POINTS: Why is this case new information? Association of the technique of lip repositioning and myotomy, the insertion of polyester threads that act as a physical barrier against recurrence. What are the keys to successful management of this case? Correct etiological diagnosis. Prior application of botulinum toxin. Respect the period of 1 month for the insertion of the polyester thread, helping to preserve the suture (limitation of movement). What are the primary limitations to success in this case? Make the patient aware not to move the lips with the hands in order to observe the incision.

BACKGROUND: A gingival display higher than 3 mm is considered a characteristic of a gingival smile (GS). Several etiological factors have been associated to GS and for this reason various treatments have been proposed according to its etiology. The aim of this study is to present a case with an alternative technique to treat GS with minimally invasive vestibular incision subperiosteal tunnel access (VISTA) and polymethyl methacrylate (PMMA) implants for lip repositioning. METHODS AND RESULTS: The patient, a 25-year-old woman diagnosed with excessive gingival exposure, had previously done botulinum toxin (BoNT) injections and did not like the result. She had a major subnasal depression and the upper lip would lodge in there during spontaneous smile. She was informed about all options of treatment and agreed to a lip repositioning installing a customized PMMA implant. CONCLUSION: This is the first study to our knowledge to present a case with use of a PMMA implant associated with the VISTA approach for lip repositioning and gingival smile correction. The results are encouraging, and the patient was satisfied with results accomplished by this technique. KEY POINTS: Why is this case new information? This is a new and innovative surgical approach for gingival smile with PMMA implants through a minimally invasive technique (VISTA). What are the keys to successful management of this case? Well-defined presurgical planning and the presence of the upper lip lodging in the subnasal depression during spontaneous smile. What are the primary limitations to success in this case? Cases with vertical maxillary excess and those in which osteotomy/osteoplasty is indicated. It is a technique-sensitive treatment dependent on the clinician's experience.

INTRODUCTION: Gingival fenestration (GF) is scarcely reported in the literature. We present a unique case of GF defect combined with gingivitis and altered passive eruption (APE). CASE PRESENTATION: An 18-year-old female patient with gingivitis, APE, and GF in the mandibular left central incisor presented for periodontal treatment. The gingival lesion was successfully treated with basic periodontal therapy gingivectomy, and gingivoplasty and resulted in an excellent aesthetic long-term outcome. This case report shows its 8-year clinical follow-up. CONCLUSION: There are no earlier reports dealing with the use of gingivoplasty for the treatment of GF, as it is not the usual therapeutic intervention for these defects. Gingivoplasty proved to be effective in treating GF. Why is this case new information? Available literature on gingival fenestration defects does not describe gingivectomy and gingivoplasty as a treatment of choice. Gingivectomy and gingivoplasty proved to be effective in treating gingival fenestration defects. What are the keys to successful management of this case? Proper diagnosis. What are the primary limitations to success in this case? Gingival fenestration has been defined when the overlying gingiva is denuded, exposing the root to the oral cavity. However, in this case report, only the crown was exposed because the patient had altered passive eruption.

BACKGROUND: Hereditary gingival fibromatosis (HGF) is characterized by sub-epithelial fibromatosis of keratinized gingiva resulting in a fibrotic enlargement of keratinized gingiva. The treatment choice is gingivectomy, which can be performed with an internal or external bevel incision conventionally. However, both techniques can hardly resume the natural status of gingiva, and have a certain recurrence rate, especially in the cases which have limited width of attached gingiva. CASE DESCRIPTION: Two cases of HGF with the chief complaint of difficulty in mastication, pronunciation, and poor esthetics were presented. After the initial periodontal therapy, a novel gingivoplasty modified with a crevicular incision was applied. A full thickness flap above the mucogingival junction and a split flap below the junction were raised. Then, fibrotic connective tissue was completely eliminated and keratinized gingival epithelium was preserved. The fibrotic alveolar bone was shaped by handpiece and bur. Finally, the flap was apically repositioned and sutured. Twelve months after surgery, the gingiva recovered with normal color, contour and consistency. CONCLUSIONS: Compared to traditional gingivectomy, modified gingivoplasty which focuses on eliminating pathological fibrotic connective tissue can completely resume the natural appearance of gingiva and demonstrate no tendency of recurrence.

This study aimed to determine whether administering botulinum toxin type A (BT) prior to surgery would stabilize surgical lip repositioning. A randomized controlled parallel-group clinical trial was performed. A total of 18 participants with excessive gingival display (EGD) were divided into two groups. For the test group (TG), BT was injected into the smile muscle locations 15 days before the surgical procedure. For the control group (CG), only lip repositioning surgery was performed. Gingival display (GD) and upper lip displacement (LD) were measured 3 and 6 months postoperatively. Data were submitted to ANOVA, Tukey, and t tests. For GD and LD, the changes were statistically significant between the measurements taken at the baseline, 3-month, and 6-month marks. The GD presented a reduction of 5.2 ± 1.1 mm in TG and 3.2 ± 1.4 mm in CG after 6 months. The LD measurements reduced 45% for TG and 26% for CG in 6 months. The injection of BT 15 days before lip repositioning surgery provided more stable results and effectively reduced the GD at 6 months.

Background and Objectives: The report describes a technique using a diagnostic mock-up as a crown-lengthening surgical guide to improve the gingival architecture. Materials and Methods: The patient's primary concern was improving her smile due to her "gummy smile" and short clinical crowns. After clinical evaluation, surgical crown lengthening accompanied by maxillary central full-coverage single-unit prostheses and lateral incisor veneers was recommended. The diagnostic mock-up was placed in the patient's maxillary anterior region and used as a soft tissue reduction guide for the gingivectomy. Once the planned gingival architecture was achieved, a flap was reflected to proceed with ostectomy in order to obtain an appropriate alveolar bone crest level using the overlay. After six months, all-ceramic crowns and porcelain veneers were provided as permanent restorations. Results: A diagnostic mock-up fabricated with a putty guide directly from the diagnostic wax-up can be an adequate surgical guide for crown-lengthening procedures. The diagnostic wax-up was used to fabricate the diagnostic mock-up. These results suggested that it can be used as a crown-lengthening surgical guide to modify the gingival architecture. Several advantages of the overlay used in the aesthetic complex case include: (1) providing a preview of potential restorative outcomes, (2) allowing for the appropriate positioning of gingival margins and the desired alveolar bone crest level for the crown-lengthening procedure, and (3) serving as a provisional restoration after surgery. Conclusions: The use of a diagnostic mock-up, which was based on a diagnostic wax-up, as the surgical guide resulted in successful crown lengthening and provisional restorations. Thus, a diagnostic overlay can be a viable option as a surgical guide for crown lengthening.

Digital guides (also known as stents) have become commonly used in daily dental practice. CBCT, digital impressions, and stereolithographic models are considered extremely helpful to create guides for the planning and resolution of surgical cases. In recent years, in periodontal surgery and in particular for the treatment of altered passive eruption (APE), there has been an increasing use of digitally designed guides to improve esthetic outcomes and achieve more predictable results. Digital custom-made guides can be used to improve safety and precision in crown lengthening procedures in patients with APE who have high esthetic expectations. Although most approaches described in the literature show guides used for primary flap or gingivectomy design, the precision of bone recontouring and ostectomy plays a key role in soft tissue rebound and in the final esthetic outcome. The present article describes a new approach using two different guides for soft tissue design in patients with APE.

OBJECTIVES: The objective of this study is to minimize gingival display by surgical repositioning of the upper lip and to suggest this technique as an alternative treatment modality to orthognatic surgery for treatment of excessive gingival display. MATERIALS AND METHODS: Forty-eight patients were selected with gingival display of more than 2 mm during maximal smiling. All patients underwent surgical repositioning of the upper lip, aimed at limiting elevator muscle activity to treat excessive gum exposure. Patients were regathered in 1 week for the follow-up postoperative symptoms according to VAS scale to evaluate pain and swelling. Reference values were given to patients. RESULTS: The study has indicated good results and stability especially to patients with skeletal class I classification along with medium and thick biotype of attached gingiva without hypermobile upper lip. CONCLUSION: Surgical repositioning of the upper lip is an effective way to improve a patient's gingival smile caused by degree I and II VME in combination with HUL as an alternative treatment modality to orthognathic surgery. This method is less invasive and cost-effective, causes minimal postoperative complications, and provides faster recovery. CLINICAL RELEVANCE: Excessive gingival display (EGD) with various etiologies requires several proper treatment modalities. The proposed modified method of lip repositioning to reduce the degree of gingival display is less aggressive, reliable, and causes fewer postoperative complications compared to orthognathic surgery.

Few long-term reports exist concerning the treatment of idiopathic gingival fibromatosis, which is a rare autosomal dominant genetic disorder associated with non-inflammatory, benign, and chronic fibrous gingival proliferation and which causes serious esthetic problems. The aim of this study was to report a case of idiopathic gingival fibromatosis treated with a gingivectomy using an inverse bevel flap method and comprehensively followed up for 15 years. A female patient visited a pediatric dentist at 7 years of age; however, a gingivectomy was not performed until the age of 20 years because of an uncertain prognosis. Now, more than 15 years after the gingivectomy, there has been no significant recurrence and the disease is well managed. Treatment by gingivectomy with an inverse bevel flap approach may provide long-term prevention of recurrence of gingival fibromatosis into adulthood. The aim of this study was to obtain new findings on the pathogenesis and prognosis of this rare disease and to review the case reports previously published.

OBJECTIVE: To systematically review the literature regarding the clinical efficacy of reducing excessive gingival display (EGD) using the surgical lip repositioning technique (LRT) and its modifications. The question to address was: "What is the clinical efficacy of the surgical LRT and its modifications in patients with EGD?" MATERIAL AND METHODS: Four databases (MEDLINE-PubMed, Scopus, EMBASE, and CENTRAL) were searched up to December 2021 (PROSPERO-CRD42020205987). Randomized, non-randomized controlled and prospective case series with a minimum of 6-month follow-up were eligible for inclusion. Two meta-analyses were performed using the mean difference (MD) between baseline and different follow-up periods (6 and 12 months). Subgroup analyses were performed using the different modifications of LRT. RESULTS: The electronic research retrieved 783 studies. Only 13 met the inclusion criteria and were included in the statistical analysis. Six modifications of the original LRT were identified. An overall EGD reduction of -3.06 mm (95%CI: -3.71-2.40), -2.91 mm; (95%CI: -3.66-2.15) and -2.76 mm; (95%CI: -3.83--1.70) was achieved after 6, 12, and 36 months, respectively, compared to baseline (P < 0.01). Meta-analysis revealed that the use of LRT with periosteal suturing showed the greatest decrease in EGD with 5.22 mm (95% CI: 4.23-6.21; P < 0.01) at 6 months and 4.94 mm (95% CI: 3.86-6.02; P < 0.01) at 12 months. CONCLUSIONS: Both the original LRT and its different modifications reduce EGD and provide good results and overall patient satisfaction at 6, 12, and 36 months of follow-up. CLINICAL RELEVANCE: Evaluating the different modifications of the LRT can be a guiding aspect for the clinical and surgical approach to be used in patients with EGD.

OBJECTIVE: Current methods of managing excessive gingival display, an aesthetic concern, with gingivectomy, orthodontic intrusion, restorative dentistry and even botulinum toxin, have often been unsatisfactory. This study evaluates the efficacy of mucosal coronally positioned flap (MCPF) for reduction of gingival display. MATERIAL AND METHODS: Eight healthy patients, above 18 years, with either short or hyperactive upper lip, gingival display ≥4 mm during smiling or vertical maxillary excess, were recruited into the study. The smile line, upper lip length, upper lip vermillion length, distance between the lips and amount of gingival display along with clinical indices were assessed. The patients then underwent MCPF procedure and were re-evaluated for healing of the surgical site after 15 days and at 3 months. Patients also provided their perceptions of outcome of treatment, through a questionnaire. Paired t test and Repeated measures ANOVA were used for data analysis. RESULTS: Significant improvement in the gingival display was noted 3 months after the procedure, while no concomitant changes were observed in other parameters like upper lip length, vermillion length and distance between the lips post operatively. CONCLUSION: The results of the study suggest that the MCPF procedure provides satisfactory results in terms of reduction of gingival display. Simplicity of the surgical procedure makes it an attractive option for patients without any gross skeletal abnormalities.

The present case series demonstrates the efficacy of an 810 nm diode laser for the surgical management of oral soft tissues related to orthodontic treatment. Three orthodontic patients aged 16-23 years underwent operculectomy, ablation of soft-tissue overgrowth over orthodontic appliance and gingivectomy along with gingival recontouring procedures, respectively, using the 810 nm diode laser. In each case, an initiated laser fibre tip was utilised to ablate the tissue at the treatment site by making a light contact with the tissue (average power output = 1-1.6 W, continuous wave emission mode, fibre diameter = 400 µm, spot size = 0.0013 cm2, energy density = 124.9-199.9 J/cm2, irradiance = 796-1273 W/cm2, total energy dose = 300-480 J). The maximum total length of treatment was 300 s (5 min). None of the patients reported any instantaneous or delayed postoperative complications over six months. Utilisation of the 810 nm diode laser for surgical management of oral soft tissues related to orthodontic treatments can be considered safe, effective and justifiable over the conventional scalpel technique; however, it must be performed by trained and experienced clinicians only.

Idiopathic gingival fibromatosis (GF), also known as gingivomatosis, is a rare condition in childhood, with an unknown aetiology. The oral manifestations of the condition are varied and depend on the severity and age of involvement. This paper describe the case of a 5-year-old male child with extensive gingival enlargement covering almost all the maxillary and mandibular teeth resulted in difficulty with speech, mastication and poor aesthetics. Clinical and radiographic examination along with haematological investigations ruled out any systemic association. The case was managed with conventional scalpel blade surgery along with electrocautery under general anaesthesia yielding good results without any recurrence after a 12-month follow-up. The results revealed that the oral manifestations of GF depend on its severity and the age of onset. Timely intervention can help to prevent associated complications in a growing child.

Excess tissue often exists distal to the upper second molar, creating a pocket in the maxillary tuberosity. When removed from this location, this tissue can serve as an optimal piece of connective tissue (CT), helping to both prevent periodontal disease and treat periodontal recession while also aiding in restorative dentistry. This tissue is an ideal CT for root coverage and soft-tissue ridge-augmentation grafting. This article provides an overview of CT grafting, including a discussion of tuberosity CT and its advantages versus palatal CT. The authors describe two techniques for harvesting tuberosity tissue for CT grafts, the distal gingivectomy technique and the distal wedge technique, and show examples of various uses of tuberosity tissue for CT grafts.
