  • collagen matrix vascularization in a peri implant Vestibuloplasty situation proceeds within the first postoperative week
    Journal of Oral and Maxillofacial Surgery, 2019
    Co-Authors: Raimund Preidl, Falk Wehrhan, Manuel Weber, Friedrich Wilhelm Neukam, Marco R Kesting, Christian Schmitt
    Abstract:

    Purpose Vestibuloplasty is a frequently performed surgical procedure to create or increase soft tissue mucosal sealing around dental restorations. Collagen matrices have exhibited comparable clinical results as free gingival grafts in the context of intraoral tissue augmentation. However, the process of matrix vascularization, the basic requirement for local healing, is incompletely understood. Therefore, this study investigated collagen matrix perfusion in a clinical intraoral setting. Materials and Methods In a prospective cohort study, Vestibuloplasty was performed during implant exposure using prefabricated collagen matrices. Matric perfusion was determined intraoperatively and at days 2, 5, 7, 14, 30, and 90 using a laser Doppler spectrophotometer measuring oxygen saturation, relative amount of hemoglobin, blood flow, and blood velocity as primary outcome variables. These parameters were compared with perfusion of the oral mucosa surrounding the matrices. Statistical analysis was performed by applying variance and regression models. Results In 10 patients (average age, 60.9 yr), Vestibuloplasty was performed exclusively in the anterior mandible. Blood flow and tissue oxygen saturation in the augmented zones markedly increased until postoperative day 5 and approximated perfusion values of the adjacent mucosa at the following 2 time points. Likewise, matrix oxygen saturation markedly increased until day 7 and subsequently converged to perfusion parameters of the surrounding mucosa at the following time points. Conclusion Flow signals in incorporated collagen matrices occurred on day 2 after Vestibuloplasty and further increased until days 5 to 7. Therefore, matrix perfusion mainly occurs within the first postoperative week, converging to perfusion levels of the surrounding mucosa with minimal alterations during the following course.

  • Vestibuloplasty porcine collagen matrix versus free gingival graft a clinical and histologic study
    Journal of Periodontology, 2013
    Co-Authors: Christian Tudor, Katrin Kiener, Stefan Eitner, Falk Wehrhan, Abbas Agaimy, Johannes Schmitt, Christian Schmitt, Karl Andreas Schlegel
    Abstract:

    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...

  • er yag laser assisted Vestibuloplasty a case report
    The Journal of Surgery, 2013
    Co-Authors: Gordana Kovacevska, Georgi Tomov, Petar Baychev, Aleksandar Kovacevski, Vesna Andreevska
    Abstract:

    The principle of a suction cup is used to retain an upper full denture. Alveolar resorption results in loss of the vestibular depth and in diminished functional surface to overcome lateral forces. Traditional surgery has the following characteristics in common-need for incisions with steel scalpels, mechanical excision of the muscle attachment from the periosteum, placement of sutures, significant postoperative discomfort, and delayed healing. When the benefits and risks of alternative treatment modalities are taken into account for this mechanical surgical procedure, minimally invasive laser-assisted soft-tissue excision and ablation seems to be very attractive technique. In the presented case report we used an Er:YAG laser (LiteTouch, Syneron, Israel) to deep the oral vestibulum of upper jaw in edentulous patient. Therefore, were indicated, we recommend the laser assisted operation technique for the partial Vestibuloplasty to assure the patients a better postoperative outcome.

  • the optimal Vestibuloplasty in preprosthetic surgery of the mandible
    Journal of Cranio-maxillofacial Surgery, 1997
    Co-Authors: T Froschl, A Kerscher
    Abstract:

    Two studies (1981-1990 retrospective, and 1989-1993 prospective) were performed to determine the optimal methods in preprosthetic surgery. The first study deals with four different types of grafts (split-thickness skin, mucosal, mesh mucosal, palatal) in combination with vestibuloplasties and lowering of the floor of the mouth. The parameters, vestibular depth, mobility and resilience of the transplants were examined. Keratinized grafts (split-thickness skin and palatal) showed advantages. On the basis of a high rate of complications at the site of harvesting of palatal mucosa and the limited amount of palatal mucosa available for grafting, we prefer a split-thickness skin graft. A second prospective study to compare the Edlan- and Kazanjian-plasty showed the disadvantages of both methods. The Edlan-plasty, in combination with implants, showed a small amount of bone resorption; the Kazanjian-plasty showed a significant loss of attached mucosa. Both methods were therefore abandoned in our clinic. For cases with insufficient width of attached mucosa, we recommend a Vestibuloplasty secondarily, with keratinized grafts. If there is a deep palatal vault and the need for a large amount of graft material, a split-thickness skin graft should be harvested. In cases of limited need and flat palatal vault, the graft can be harvested from the palate.
