Contemporary minimally invasive VISTA approach for gingival recession coverage: a case series.

Gingival recession is a common problem that requires periodontal surgery to restore esthetics. The vestibular incision subperiosteal tunnel access (VISTA) technique is a minimally invasive recession coverage method that has gained popularity. This case series reviews the treatment outcomes in 10 patients with a total of 28 Miller Class I or Class II recession defects in the maxillary anterior region. The defects were treated with the VISTA technique alone without any grafting material. The clinical parameters measured at baseline and at 3- and 6-month follow-up examinations were probing depth, clinical attachment level, Gingival Index, width and thickness of attached gingiva, and height of gingival recession. Statistical analysis (repeated-measures analysis of variance with a post hoc Bonferroni test) revealed that all clinical parameters except probing depth and thickness of attached gingiva showed statistically significant improvement from baseline to the follow-up examinations (P < 0.001). A mean root coverage of 78.99% was achieved. Even when performed without any grafting material, the VISTA technique is a reliable method to obtain recession coverage in the maxillary anterior region.

VISTA technique in combination with chorionic allograft for gingival recession coverage: a case series.

The vestibular incision subperiosteal tunnel access (VISTA) technique, a minimally invasive procedure, achieves multitooth recession coverage with only a single access incision. Use of fetal membranes such as the amnion and chorion has become increasingly popular in the field of dentistry due to their lack of immunogenicity and added advantage of growth factors. The present case series aimed to provide information regarding the potential advantage of placing a chorionic membrane in combination with the VISTA technique to achieve recession coverage. Eight healthy adult patients presenting with 24 Miller Class I multitooth gingival recession defects were surgically treated with the VISTA technique and a chorionic membrane. The clinical parameters measured at baseline and 1, 3, and 6 months postoperatively were probing depth, clinical attachment level, width of keratinized gingiva, thickness of attached gingiva, and height of gingival recession. A repeated-measures analysis of variance with a post hoc Bonferroni test was carried out to compare the baseline values with the 1-, 3-, and 6-month postoperative values. The mean (SD) height of gingival recession was significantly reduced from 2.04 (0.67) mm at baseline to 0.71 (0.71) mm at 6 months (P < 0.001). In addition, there were statistically significant gains in the clinical attachment level, width of keratinized gingiva, and thickness of attached gingiva from baseline to 6 months postoperatively (P < 0.001). The probing depth remained the same at all measurement times. The VISTA technique provided good results in terms of recession coverage. Although there was an improvement in the gingival biotype, the placement of a chorionic membrane did not provide any advantage in terms of percentage of root coverage.

The VISTA Approach in Canine Disimpaction.

Canine disimpaction is always a challenging orthodontic treatment overall, even when the impacted permanent canine is in a high position, especially when in tight relation with the upper incisors' roots. Conventional treatment methods are usually not capable of performing the correct force direction, consisting of the contemporary movement in the distal and vestibular directions of the canine crown, often provoking, as side effects, the presence of decubitus on the mucous of the lips and cheeks or a poor final appearance of the periodontal support of the disimpacted canine. Among the different approaches, the vertical incision subperiosteal tunnel access (VISTA) technique shows good performance with regard to the direction of the forces and the canine's periodontal conditions when erupted; it is usually realized through an elastic chain connected to a temporary anchorage device (TAD) in the posterior area. In this paper, a different protocol for the VISTA method is also presented, to be resorted to in cases of difficult miniscrew positioning due to the anatomic conditions or stage of dentitions. The new protocol also considers the use of nickel-titanium coil springs in order to avoid the need of frequent reactivation of the device and consequent patient discomfort, highlighting its advantages and indications with respect to the traditional approach.

Multiple Gingival Recession Coverage Treated with Vestibular Incision Subperiosteal Tunnel Access Approach with or without Platelet-Rich Fibrin - A Case Series.

BACKGROUND: Gingival recession involves both soft tissue and hard tissue loss. In this evolutionary era of dentistry, newer techniques have evolved for complete coverage of isolated recession defects. Since 2012, vestibular incision subperiosteal tunnel access (VISTA) technique was used with various regenerative membranes to treat multiple recession defects (MRDs). Platelet-rich fibrin (PRF) membrane, a pool of growth factors but have any added advantage to recession coverage techniques is controversial. Thus, in this case series, we compare the effect of VISTA with or without PRF-membrane for the treatment of Classes I and III MRDs. SUBJECTS AND METHODS: Four patients between of age 30 and 40 years (two patients having bilateral Class I and another two having bilateral Class III MRDs) were selected from the Department of Periodontics, ITS Dental College, Greater Noida and designated as Case I-IV simultaneously. Recession defects at antagonist sites in each patient were corrected by VISTA approach with or without PRF-membrane. Recorded clinical parameters included recession depth, recession width, pocket probing depth, and clinical attachment level (CAL) at baseline and 6 months postoperatively. RESULTS: Patients having Class I recession defects showed almost complete root coverage with VISTA technique alone and reflected no added advantage of PRF-membrane. However, patients with Class III recession defects treated with VISTA + PRF-membrane showed more reduction in recession depth and gain in CAL as compared to sites treated with VISTA only. CONCLUSION: VISTA alone is a convenient technique for treatment of Class I MRDs. Addition of PRF-membrane for Class III recession defects give better outcome in term of reduction of recession depth and gain in CAL 6 month postoperatively.

Recessões gengivais múltiplas na zona estética ­ relato de caso com a técnica Vista / Multiple gingival recessions in the esthetic zone ­ a case report using the Vista technique

O objetivo deste trabalho foi demonstrar a resolução de recessões gengivais múltiplas na zona estética. Uma paciente de 32 anos e idade apresentou-se com recessões classe I de Miller, restaurações cervicais classe V, e sensibilidade radicular localizada. O exame clínico não mostrou perda óssea proximal ou invasão da linha mucogengival. Após a anestesia, as restaurações classe V foram removidas, com raspagem e alisamento radicular, ácido cítrico e EDTA. O tecido mole foi manejado usando a técnica Vista, sem alteração da margem coronal da papila interdentária. As suturas foram ancoradas nas faces vestibulares dos caninos e incisivos usando-se resina composta. O creeping attachment foi observado 15 dias depois. Nos dois meses seguintes, a sensibilidade radicular foi controlada com uso de fluoretos. Após cinco meses, a estabilidade do ganho tecidual adquirido foi constatada. Os resultados observados compensaram a complexidade desta técnica.

The aim of this paper was to demonstrate a solution for multiple gingival recessions in the esthetic zone. A 32-years old female patient presented with Miller's class I recessions, type V cervical restorations, and localized root sensitivity. Upon clinical exam, no proximal bone loss and invasion of the mucogingival line were identified. After anesthetic infiltration, the class V restorations were removed, followed by root debridement and polishing, citric acid, and EDTA application. Soft tissue management was performed with the Vista technique, with no changes on the coronal margins of interproximal papillae. Sutures were anchored at the buccal tooth surfaces with a flow composite resin. Fifteen days later, the creeping attachment was observed. On the next two months, root sensitivity was controlled by the use of local fl uoride solution. After 5 months, soft tissue gain and stability were confi rmed. The observed outcomes can counterbalance the complexity of this technique highlighting its importance in the daily practice.
