Excessive gingival display (EGD) is a challenge for dentists attempting to provide their patients a pleasant smile. EGD associated with hyperactivity of the smile elevator muscles can be treated with various surgical techniques; regardless of which technique is used, to achieve a predictable result with long-term stability limiting upper lip movement when the patient smiles, a firm muscle containment is imperative. This report describes an innovative suture procedure associated with a lip repositioning technique aimed at maintaining the traction and containment of the smile elevator muscles...

The aim of this study was to assess the effect of isolated V-Y plasty on lip lengthening and the treatment of gummy smile. An isolated V-Y plasty was performed on 14 patients with a gummy smile. In each case, measurements of upper lip length and gingival display were recorded from posed-smile photographs taken preoperatively and at 1, 3, and 6 months postoperatively. Gingival display decreased significantly and lip length increased significantly over all intervals investigated. Applying this technique after Le Fort I surgery may be beneficial; however, as with other injection or surgical lip lengthening methods, its stand-alone application should be questioned...

Beautiful smile is a booster to person's confidence. Gummy smile is a term used for excessive gingival display (EGD). Its etiology is multifactorial. Bone vertical maxillary excess (VME) is one of the cause of EGD. In this case series, lip repositioning was performed to treat mild to moderate degree of gingival display ( 2 to 8 mm) due to VME. Lip repositioning is simple, promising, meticulous and comparatively cheap alternative technique for treating gummy smile.

BACKGROUND: Tooth movement out of anatomic limitations was assisted by augmented corticotomy using deproteinized bovine bone mineral. METHODS: Lip protrusion can be reduced by premolar extraction followed by retraction of the anterior teeth. Surgical intervention is appropriate when the alveolar bone housing of the anterior region is insufficient for the tooth movement. In this patient, corticotomy in upper palatal area and anterior segmented osteotomy in the mandible were performed...

PURPOSE: In Le Fort 1 osteotomy when a maxillary impaction is necessary, surgeons have to face different anatomical problems. (1) To determine the best bone resection route, they have to consider the situation of dental roots, infraorbital foramen and maxillary artery. (2) In case of Le Fort 1 osteotomy combined with a mandibular sagittal split osteotomy, the palate has to be replaced in horizontal position although there is no anatomical landmark. (3) In case of Gummy smiles, it can be due to either long face or short upper lip...

Orthodontic treatment in adult patients with a skeletal discrepancy can be challenging. In this case report, we achieved both sagittal and vertical control by combining the classic sliding mechanics straight-wire technique with miniscrew anchorage. We treated a 21-year-old Chinese woman with a severe high mandibular plane angle, a retrusive chin, and a gummy smile. Her diagnosis included a skeletal Class II skull base with a mild anterior open bite, a protrusive maxilla, and a backwardly rotated mandible. This case underscores the importance of anchorage control in both the sagittal and vertical directions...

In this case report, we present the orthodontic and surgical management of an 18-year-old girl who had a severe craniofacial deformity, including maxillary prognathism, vertical maxillary excess (gummy smile), mandibular retrognathism, receding chin, and facial asymmetry caused by unilateral temporomandibular joint ankylosis. For correction of the facial asymmetry, the patient's right mandibular ramus and body were lengthened via distraction osteogenesis after 5 months of preoperative orthodontic therapy. Subsequently, extraction of 4 first premolars, bimaxillary anterior segmental osteotomy, and genioplasty were simultaneously performed in the second-stage operation to correct the skeletal deformities in the sagittal and vertical planes...

A 20-year-old woman visited the office complaining of a gummy smile and lip protrusion. She was diagnosed with vertical maxillary excess without open bite and skeletal Class II hyperdivergent pattern. She refused the surgical-orthodontic treatment option, although she wanted to correct the gummy smile and retruded chin. Differential intrusion of anterior and posterior teeth in both arches was necessary to maximize the skeletal treatment effects. In the maxilla, one palatal temporary anchorage device (TAD), an archwire with an accentuated curve of Spee, and a transpalatal arch were applied...

Botulinum toxin is a polypeptide protoxin synthesized by Clostridium botulinum that results in localized reduction of muscle activity by inhibiting acetylcholine release at the neuromuscular junction. In 2004, the US Food and Drug Administration approved its application in the treatment of various medical conditions, such as facial wrinkles, strabismus, cervical dystonia, blepharospasm, and hyperhidrosis. Later, its application extended to improving dental esthetics and gummy smile. It was found to be a safe and effective alternative to medical therapy to treat various head and neck disorders that have a neurologic component...

Gingival hyperpigmentation and the condition known as gummy smile are very common dental cosmetic problems. Gingival hyperpigmentation arises due to the excess presence of melanin in certain regions of the gums. In the case of gummy smile, more than the required amount of gingival tissue is exposed upon smiling. An aesthetically pleasing smile should expose only a negligible amount of gingival tissue. Gummy smile and gingival hyperpigmentation can have detrimental effects on the aesthetic quality of a smile, and thereby a wide variety of treatment options must be taken into consideration depending patient outcome objectives...

Prior to initiating any treatment, it is necessary to visualize the desired outcomes. It then becomes possible to formulate the steps required to achieve this result. Digital Smile Design (DSD) utilizes patient input and information gathered through diagnostic procedures to create an esthetic treatment scheme. In the case presented here, the NYUCD Esthetic Evaluation Form, intraoral and extraoral photographs, mounted diagnostic casts, physical examination, and radiographs were the diagnostic modalities. The gathered information served as a starting point for a wax-up and intraoral mock-up...

One of the most frequent causes of gummy smile is an altered eruption, ie, the gingival margins are located at a more coronal position than normal. These cases can be successfully treated with a periodontal surgical approach. Several techniques may be used, depending on the different anatomic variations. The surgery must be carefully planned so as to avoid discrepancies between the soft tissues and the teeth. Clinical examination and radiographic evaluation will allow clinicians to determine the position of the gingival margin, bone crest, and cemento-enamel junction and thus elicit a correct diagnosis of the subtype of altered eruption...
