A smile is a mesmerizing expression of joy, success, courtesy and reveals self-confidence. The harmony of the smile is determined not only by the shape, position and the color of teeth, but also by the gingival architecture. Gingival tissues form an important part of what we can consider to be a pleasing smile. The elegance of this pleasant smile could be, affected by highly pigmented gingiva. This gingival pigmentation occurs as a result of melanin granules, which are produced by melanoblast. Although melanin pigmentation does not present a medical problem, demand for cosmetic therapy is commonly sort by people with moderately pigmented gingiva...

Gingiva is a unique tissue which protects the underlying periodontal tissues from consistent mechanical and bacterial aggressions. Molecular analysis of gingiva is likely to improve our understanding of the underlying biological processes at work. The aim of this preliminary exploratory study is to analyze the proteomic profile of healthy gingiva and to detect prominently expressed proteins. Gingival tissue samples were obtained from periodontally healthy individuals who underwent surgical crown lengthening procedure...

This study evaluated use of a solid-state laser to avoid the flap technique and suturing. An Er:YAG laser was used in 26 consecutive patients referred for osseous crown lengthening in 32 posterior teeth. The distance from the planned restoration margin to the alveolar crest (B) satisfied a 3-mm dentogingival complex. No tissue necrosis and no significant change in the distance from the gingival margin to B or probing depth were detected at 3 and 6 months. Minimally invasive Er:YAG laser surgery decreases the time needed to establish the gingival margin necessary for definitive restoration...

Esthetic implant therapy can be challenging in the anterior maxilla, and meticulous treatment is often required to deliver optimal esthetics. Close collaboration between surgical and prosthetic team members using the novel approach of prosthetic crown lengthening helped camouflage a shallow implant platform location, providing the proper gingival frame for esthetic restorations. This case report presents an interdisciplinary approach that included ridge augmentation, second-stage crown lengthening, and prosthetic soft tissue manipulation to address an implant placed too shallow in the alveolus of an extraction socket...

Crown lengthening by forced eruption is usually followed by conventional surgical procedures. The aim of the present study was to evaluate clinical use of Nd:YAG laser fiberotomy in crown lengthening by forced eruption as an alternative to surgery. Patients who needed crown lengthening were enrolled in this prospective case series and underwent forced eruption. Fiberotomy by Nd:YAG laser was performed 2 days after initiation of forced eruption and every 2 weeks afterward to reach optimum clinical crown length...

Early wound healing after periodontal surgery with or without enamel matrix derivative/biphasic calcium phosphate (EMD/BCP) was characterized in terms of soft tissue closure, changes of microcirculation, and expression of pro- and anti-inflammatory cytokines in gingival crevicular fluid/wound fluid (GCF/WF). Periodontal surgery was carried out in 30 patients (18 patients: application of EMD/BCP for regeneration of bony defects; 12 patients: surgical crown lengthening (SCL)). Healthy sites were observed as untreated controls...

Excessive gingival display is considered unattractive by many patients. A combination of surgical approaches may be required to correct this problem. Clinical crown lengthening involves recontouring crestal bone levels and moving the gingival margin in an apical direction. Lip repositioning reduces gingival display by limiting upper lip movement when smiling. This article describes a case in which a combination of clinical crown lengthening and lip repositioning was used to correct excessive gingival display when smiling...

The aim of this case report was to describe the surgical sequence of crown lengthening to apically reposition the dentogingival complex, in addition to an esthetic restorative procedure. Many different causes can be responsible for short clinical crown. In these cases, the correct execution of a restorative or prosthetic rehabilitation requires an increasing of the crown length. According to the 2003 American Academy of Periodontology (Practice Profile Survey), crown lengthening is the most habitual surgical periodontal treatment...

The aim of the present case series article was to provide a standardized approach for the early restorative phase after a crown-lengthening surgical procedure. Different advantages can be ascribed to this approach: the clinician can prepare a definitive prosthetic finishing line in the supragingival location; the early postsurgical temporization allows the conditioning of soft tissues, especially the interdental papillae, during their maximum growing phase; and the clinician can choose the time for the definitive prosthetic rehabilitation in a patient-specific manner according to the individual potential and duration of the soft tissue rebound...

The aims of surgical crown lengthening procedures are to improve prosthetic reconstructions at teeth with limited hard tissue, to prevent periodontal problems and/or to improve esthetics. When planning and performing surgical crown lengthening, it is important to consider not only periodontal and technical aspects but also the gingival profile of the neighbouring teeth. This paper presents the systematic approach starting with the diagnosis and indication to the performed treatments and the obtained results and gives clinical recommendations...

This is the second paper in this two-part series. Paper one provided an overview of managing gingival tissue excess and paper two will focus on increasing clinical crown height to facilitate restorative treatment. Crown lengthening is a surgical procedure aimed at the removal of gingival tissue with or without adjunctive bone removal. The different types of procedure undertaken will be discussed over the two papers. In order to provide predictable restorations, care must be taken to ensure the integrity of the margins...

Crown lengthening surgery aims to increase the amount of supragingival tooth tissue by resection of the soft and/or hard tissues to enable otherwise unrestorable teeth to be restored by increasing the retention and resistance forms of the teeth. Restoration of the worn dentition may require significant prosthodontic knowledge and skill. A prosthodontist should be involved from the beginning of the management of the patient. A number of key stages should be considered for correct management. Although the periodontist may guide the prosthodontist with regards to what may or may not be possible surgically, the overall treatment plan should be prosthodontically driven...

Oblique crown-root fracture in the cervical third of the root is a common event following trauma to the anterior region of the mouth. As a result, sound tooth structure coronal to the attachment apparatus may not be available for restorative needs. Invasion of biological width by fracture line presents a clinical challenge in restorative planning. Placing a restoration margin on sound tooth structure within the dentogingival biological width might result in violation of biological width and should be considered a restorative failure...
