Surgical treatment of localized gingival recessions using coronally advanced flaps with or without subepithelial connective tissue graft.
2015
Background A coronally advanced flap with subepithelial connective tissue graft is the gold standard surgical treatment of gingival recessions, since it offers a higher probability of achieving complete root coverage compared with other techniques. However, optimum short- and middle-term clinical results have also been obtained with coronally advanced flaps alone. The aim of the present study was to evaluate the results obtained by the surgical treatment of localized gingival recessions using coronally advanced flaps with or without subepithelial connective tissue graft. Material and Methods The reduction of recession height was assessed, together with the gain in gingival attachment apical…
Recession Coverage Using Soft Tissue Substitutes
2018
Today, a variety of surgical procedures can be used to successfully treat gingival recession defects. Among them, the autogenous connective tissue graft in conjunction with a coronally advanced flap is commonly considered the gold standard procedure. However, the most significant disadvantages of this procedure are the potential morbidity associated with autogenous tissue harvesting and the limited availability of donor tissue. For these reasons, alternative surgical procedures using membranes, enamel matrix derivative, and soft tissue graft substitutes have been proposed and tested. The aim of the present chapter is to provide an overview on the use of soft tissue substitutes as a possible…
Subepithelial connective tissue graft with or without enamel matrix derivative for the treatment of Miller class I and II gingival recessions: a cont…
2012
Background The aim of this study was to evaluate whether the combination of enamel matrix derivative (EMD) with subepithelial connective tissue graft (SCTG) plus coronally advanced flap (CAF) would improve the treatment outcomes of Miller class I and II gingival recessions when compared with the same technique (SCTG plus CAF) alone. Methods The study was designed as a randomized, parallel, controlled, double-blinded clinical trial. Forty-two patients were randomly assigned in the test group (SCTG plus EMD) and in the control group (SCTG). Patients had at least one gingival recession ≥ 2 mm. The clinical parameters were evaluated at baseline and at 14 d, 1, 3, 6 and 12 mo follow-up time poin…
Preliminary evaluation of near-infrared vein visualization technology in the screening of palatal blood vessels.
2018
Background Avoidance from palatal blood vessel rupture is a major concern during the palatal soft tissue graft surgery. There is no defined chair-side and case-specific palatal blood vessel detection approach to facilitate the harvesting process. The objective of this pilot study is to assess the feasibility of a near-infrared vein visualization system in the screening process of palatal blood vessels. Material and Methods An extraoral vein visualization device (AccuVein AV400) was applied to a total of 304 hemi-maxilla of 152 individuals by two blind examiners. The study groups were classified according to their maximum inter-incisal measurements. The distances between the coronal border o…
A novel, fully digital approach to quantifying volume gain after soft tissue graft surgery. A pilot study
2020
Objective Measuring soft tissue thickness after mucogingival surgery has traditionally been performed by means of a calibrated transgingival probe. The main aim of this study was to apply a non-invasive technique based on digital images formatted as Standard Tessellation Language (STL) files to quantify soft tissue volume after connective tissue grafting. Clinical innovation report Ten patients who presented Cairo Class I gingival recession were selected for connective tissue grafting using the tunnel technique. In all patients, the initial position of the gingiva and quantity of keratinized tissue were recorded, and gingival recession was scanned with an intra-oral scanner. Six months afte…
Clinical evaluation of subepithelial connective tissue graft and guided tissue regeneration for treatment of Miller's class 1 gingival recession: com…
2013
Objectives: The present study aims to clinically compare and evaluate subepithelial connective tissue graft and the GTR based root coverage in treatment of Miller’s Class I gingival recession. Study Design: 30 patients with at least one pair of Miller’s Class I gingival recession were treated either with Subepithelial connective tissue graft (Group A) or Guided tissue regeneration (Group B). Clinical parameters monitored included recession RD, width of keratinized gingiva (KG), probing depth (PD), clinical attachment level (CAL), attached gingiva (AG), residual probing depth (RPD) and % of Root coverage(%RC). Measurements were taken at baseline, three months and six months. A standard surgi…
Complications of harvesting a connective tissue graft from the palate. A retrospective study and description of a new technique
2017
Background Connective tissue graft (CTG) is considered as the gold standard for the treatment of gingival recessions (GR). There are few studies assessing the complications that can arise in the donor site when harvesting a connective tissue graft (CTG) and how the harvesting technique can influence those complications. Material and methods A retrospective clinical study was carried out in order to compare the complications observed in 40 patients with Miller class I, II and III GR ≥ 3 mm, after using the trap-door technique (TD) in the control group and a newly described technique, the "UPV/EHU technique", in the test group. Patients were consecutively allocated to each treatment group. Pa…
Complications Associated with Recession Coverage Procedures
2018
Various surgical techniques have been proposed to obtain predictable and esthetic root coverage. In general, these techniques may include the use of pedicle soft tissue grafts, free soft tissue grafts, and soft tissue graft substitutes. Overall, these surgical procedures have been shown to be safe, effective, and well-tolerated by the patients. However, as with any surgical procedure, complications and treatment failures can occur. Therefore, the clinician should have a thorough knowledge of potential complications associated with these procedures and strategies for their prevention and management. This chapter provides an overview of the most common complications and atypical healing respo…
Outcome measurements following palatal soft tissue graft harvesting: A review
2021
Background Free gingival graft (FGG) and connective tissue graft (CTG) are two of the most commonly techniques performed in periodontal and peri-implant plastic surgery. Although several outcome measurements have been proposed for evaluation of palatal wound healing and patient morbidity, a comprehensive review about these variables is lacking. The objective of this review is to present comprehensive information about outcome measurements related to postoperative palatal wound healing and postoperative patient-reported morbidity after FGG or CTG procedures. Material and methods An electronic search of English language dental literature in the Medline database via PubMed access was conducted…
Optical quality of hyperopic and myopic phakic intraocular lenses
2013
Aims: To assess and compare the optical quality of the myopic and hyperopic implantable collamer lens (ICL) from its wavefront aberrations for different powers and pupil diameters. Settings and Design: Prospective study. Material and Methods: The wavefront aberrations of two myopic (−3 and −6 diopters (D)) and two hyperopic V4b ICLs (+3 and +6D) were measured in vitro . To assess and compare the optical quality of different powers of ICLs, we analyzed the root mean square (RMS) of total higher order aberrations (HOAs), trefoil, coma, tetrafoil, secondary astigmatism, and spherical aberration at 3- and 4.5-mm pupil. In addition, the point spread functions (PSFs) of each ICL evaluated were ca…
