Particularly in the premaxillary area, the stability of hard and soft tissues plays a pivotal role in the success of the rehabilitation from both a functional and aesthetic aspect. The present case report describes the clinical management of a localized alveolar ridge atrophy in the area of the upper right canine associated with a thin gingival biotype with a lack of keratinized tissue. An autogenous bone block harvested from the chin associated with heterologous bone particles was used to replace the missing bone, allowing for a prosthetic driven implant placement...

OBJECTIVE: Amelogenesis imperfecta (AI) is a heterogenous genetic disorder that interferes with normal enamel formation in the absence of systemic disorders. The patients' main concerns are caries susceptibility, poor esthetics, and generalized sensitivity. There is a broad clinical spectrum, from discolorations to consequent enamel alterations. This case report describes the 15-year case study and the full-mouth rehabilitation of two siblings affected by a hypocalcified AI. Clinical Considerations: In these two patients, conservative care with stainless steel crowns and direct composite restorations was undertaken to restore function and esthetics and to reduce sensitivities in primary and mixed dentitions...

Ectodermal Dysplasia Syndrome (EDS) is mainly X-linked inherited disorder with male predominance. According to Lyon hypothesis, female patients may show partial expression of EDS. Oral findings include hypodontia, rarely anodontia, protuberant lips, hyposalivation, conical teeth and loss of vertical dimension. The alveolar process fails to develop in the three dimensions. Such patients present a challenge to dental treatment due to an irregular residual ridge. This case report presents oral, functional and aesthetic rehabilitation of a 21-year-old female diagnosed with EDS using implants in the anterior maxilla at the sites of the canines bilaterally...

INTRODUCTION: A canted occlusal plane presents an unesthetic element of the smile. The correction of this asymmetry has been typically considered difficult by orthodontists, as it requires complex mechanics and may sometimes even require orthognathic surgery. OBJECTIVE: This paper outlines the case of a 29-year-old woman with Class II malocclusion, pronounced midline deviation and accentuated occlusal plane inclination caused by mandibular deciduous molar ankylosis...

AIM: The aim of this systematic review was to identify studies that examined maxillary lateral incisor agenesis treatment, by either orthodontic space closure by canine mesial repositioning and reshaping, or by a prosthodontic intervention, in order to compare the biological, functional and aesthetic outcomes of these two approaches. MATERIALS AND METHODS: An electronic MEDLINE search was conducted by two independent reviewers in order to isolate English language articles, published in scientific journals between January 1975 and March 2015, reporting on treatment of agenesis of maxillary lateral incisors, accomplished either by canine orthodontic repositioning or prosthodontic intervention...

OBJECTIVES/HYPOTHESIS: Traditional semi-occluded vocal tract therapies have the benefit of improving vocal economy but, do not allow for connected speech during rehabilitation. In this study, we introduce a semi-occluded face mask (SOFM) as an improvement upon current methods. This novel technique allows for normal speech production, and will make the transition to everyday speech more natural. We hypothesize that use of an SOFM will lead to the same gains in vocal economy seen in traditional methods...

The main function of the forearm is the supination, which is achieved largely through the biomechanical characteristics and stability of the distal radio-ulnar joint. There are several surgical techniques for the treatment of distal radio-ulnar dislocations isolated or associated with a fracture. We report the case of a canine trainer who was bitten at the wrist and distal forearm that came to the emergency department in where distal ulnar dislocation with muscle tendon exposure was diagnosed. Due to the offending agent and multiple soft tissue injuries the treatment with standard techniques was impossible...

OBJECTIVE: Placement of a dental implant during early adolescence may result in an unesthetic outcome or even loss of function. The presented case describes the treatment of infraoccluded dental implants and the esthetic complications for a young adult female who had received two dental implants in the canine positions when she was 16 years old. Clinical considerations: After examination and diagnosis, a multidisciplinary approach was implemented, including the removal of one infraoccluded implant, followed by hard and soft tissue reconstruction prior to implant replacement into an ideal three-dimensional position...

Agenesis of the maxillary lateral incisors poses particular problems for dentists, orthodontists and patients. Treatment of these ageneses is still highly controversial, both functionally and esthetically. The patient's smile and anterior guidance are affected and must be restored. The diagnosis is easy. Few mistakes are possible. However, managing patients with missing maxillary lateral incisors can be a challenge, commonly involving two possible treatment approaches: space opening to replace the missing lateral incisor with a prosthetic unit (denture, bridge or implant) or orthodontic space closure replacing the missing lateral incisor with the maxillary canine camouflaged to mimic the appearance of a lateral incisor...

Patients suffering from Ellis-Van-Creveld syndrome are a challenge for dental management. Aesthetics are a major concern with limited manual dexterity, making choice of treatment critical. A 38 year old female diagnosed with Ellis-Van-Creveld syndrome presented with stained teeth and un-aesthetic smile and related that to her low self-esteem and depression. Intra-oral examination revealed mal-aligned megadont central incisors in the maxillary arch, fused mandibular canines with laterals and missing central incisors with space discrepancy and pronounced reverse over jet and overbite...

A live-stranded harbor porpoise Phocoena phocoena was found on the west coast of the Dutch island Texel (North Sea) and transported to a rehabilitation center for small cetaceans, where it underwent a veterinary health check. Cardiac auscultation revealed a systolic cardiac murmur with the point of maximal intensity in the right hemithorax with an intensity of IV out of VI. Transthoracic echocardiography revealed a congenital ventricular septal defect with left-to-right shunting. Because the left atrium was not dilated according to the reference range of canine left atrium to aortic ratio, the presence of congestive heart failure was considered very unlikely...

Impacted maxillary canine teeth commonly occur in the general population. The traditional therapeutic approach comprises fenestration and orthodontic traction; however, if traction is not feasible or the patient refuses orthodontic treatment, an alternative solution is to remove the impacted tooth and immediately place an implant. This technical note describes a novel surgical approach to rehabilitation after impacted canine tooth removal, entailing immediate placement of a long implant in combination with regenerative materials and a barrier...

Canine protected articulation is widely accepted for patients requiring extensive oral rehabilitation. Computer-aided design and computer-aided manufacturing (CAD/CAM) restorations have been primarily designed in occlusion at the maximum intercuspal position. Designing a virtual articulator that is capable of accepting excursive occlusal records and duplicating the mandibular movements is a challenge for CAD/CAM technology. Modifying tooth shape using composite resin trial restorations to produce esthetic results and later scanning the modified teeth to create milled crowns is becoming a popular use of the CAD/CAM technology...

Intervertebral disk disease (IVDD) is a major spine disorder in canines that causes neurological dysfunction, particularly in the thoracolumbar area. Analgesic and anti-inflammatory drugs are typically used to reduce nociceptive signals to decrease canine suffering. Bee venom (BV) has been reported to exert anti-inflammatory and analgesic effects. Injection of BV at acupoints has been widely used to treat clinical disorders including inflammation, pain, and arthritis. The current study was intended to determine whether BV injections at acupoints can enhance treatment of canine neurological dysfunction caused by IVDD...

Long implants (LI, i.e. longer than 13 mm) are thought to give longer survival than standard length fixtures. The aim of this study is to evaluate the survival rate of 780 LI. In the period between January 2008 and December 2013, 877 patients (498 females and 379 males) were operated at the BDD private Practice Clinic (Milan, Italy). The mean post-surgical follow-up was 30±17 months (max – min, 84 – 1). One thousand seven hundred and fifty-three fixtures (EDIERRE Implant System SpA, Genoa, Italy) were evaluated in the present study, 780 15 mm long (LI) and 972 13 mm long (i...
