Aesthetic Perceptions - Is There a Difference?

Introduction: In recent times, the demand for aesthetic dentistry has increased, with patients presenting for treatment expecting an improvement in their aesthetics. Therefore, it is increasingly important for the dental profession to appreciate perceptions of dental aesthetics in order to provide a patient-centred service.

Objectives: The aim of this study is to quantify perceptions of aesthetics using a cross-sectional survey design. The hypotheses being tested were that differences exist in aesthetic perceptions of 1) dentists and dental students, 2) different age ranges and 3) gender.

Methods: A questionnaire was distributed to dental staff and students in the Cork University Dental School and Hospital. The questionnaire sought information relating to aesthetic perceptions by asking participants to compare photographs of smiles.

Results: 100 questionnaires were returned. It was found that differences existed in perceptions of dentists and dental students when certain aspects of a smile were evaluated, in particular when a minor flaw was present in a smile in addition to the major flaw being tested. Assuming that flaws were detected, more dental students (34%) than dentists (26%) were found to prioritise colour above more subtle flaws, such as a centreline shift. However, most results between the two groups are comparable in terms of their prioritising of importance of particular aspects of a smile, with no large significant differences.

Conclusion: Differences exist in aesthetic perceptions of dentists and dental students, especially with regard to tooth colour.

Laminate veneers - a review and clinical case

The laminate veneers are great choice for rehabilitation for anterior segment of the mouth. Actually, due the employment of dental cements and bonding to dentin, the uses of laminate veneers is an effective and conservative treatment, showing a high rate success rate. This paper presents a clinical case of 50 years old male, J.C.H, who have a chief complaint of an unattractive smile. After the diagnosis and planning, 10 laminate veneers were placed from the second bicuspid (15) to the second bicuspid (25). The correct indication of laminate veneers allows restorations with appropriate esthetic and patient's satisfaction with immediate effect on quality of life. © 2011 Nova Science Publishers, Inc.

Resolução estética associando prótese sobre implante e prótese convencional na região anterior

The combination of several methods for solving aesthetics in a clinical case can be a complicating factor. The diagnosis and planning of the event held in conjunction with the dental technician expand the possibilities of success. The present case illustrates the aesthetic resolution through the association of implant- and tooth-supported prostheses using metal free ceramic systems. A 38-year old male patient presented with a complex smile. After diagnosis and treatment planning, two ceramic crowns were made, one on tooth 11 and one on the implant region 21, along with a laminated porcelain veneer on the region of 12. Aesthetic needs of the patient are predictable only with a sound diagnosis.

Solução estética para prótese sobre implante

Próteses sobre implantes esteticamente favoráveis estão diretamente relacionadas com a condição dos tecidos moles e duros que as envolvem. A preservação dos tecidos mucogengivais ao redor de implantes dentários instalados na maxila anterior propicia um sorriso harmonioso, com uma estética bastante agradável. No entanto, em alguns casos, isso não ocorre principalmente pela grande reabsorção tecidual na região, na qual deveria ter sido realizado enxerto ósseo, antes mesmo da instalação dos implantes. Desse modo, o objetivo deste trabalho foi apresentar uma solução reabilitadora estética para essas possíveis falhas durante o planejamento com reabilitações sobre implantes, por meio de gengiva artificial cerâmica.

Emprego de técnica cirúrgica e materiais adesivos diretos no fechamento de diastema

The following is a clinical case report of a patient whose main complaint was the presence of a generalized spacing in the anterior maxillary segment. After meticulous clinical analysis and discussions of the clinical procedures to be adopted, a labial frenectomy was our first choice, so that we could reduce the diastemas directly using composite resin. It was observed that the association of clinical and restorative procedures was capable of giving back shape, function and dental aesthetics, allowing to the young patient the satisfaction of smiling without any fear.

A Randomized comparative clinical study of two surgical procedures to improve root coverage with the acellular dermal matrix graft

Aim This randomized, controlled, clinical study compared two surgical techniques for root coverage with the acellular dermal matrix graft (ADMG) to evaluate which procedure could provide better root coverage and greater amounts of keratinized tissue. Materials and Methods Fifteen pairs of bilateral Miller Class I or II gingival recessions were treated and assigned randomly to the test group, and the contra-lateral recessions were assigned to the control group. The ADMG was used in both groups. In the control group, the graft and flap were positioned at the level of the cemento-enamel junction (CEJ), and in the test group, the graft was positioned 1 mm apical to the CEJ and the flap 1 mm coronal to the CEJ. The clinical parameters were taken before the surgeries and after 6 months. The gingival recession area, a new parameter, was measured in standardized photographs through a special device and software. Results There were statistically significant differences favouring the proposed technique for all parameters except for the amount of keratinized tissue at 6 months. Conclusions The proposed test technique is more suitable for root coverage procedures with ADMG, and the new parameter evaluated appears valuable for root coverage analysis.

Reabilitação estética com facetas em pacientes com amelogénese imperfeita

A Amelogénese Imperfeita é uma anomalia hereditária que interfere no desenvolvimento do esmalte, pode variar em seu grau de intensidade, podendo afetar o esmalte tanto na sua qualidade, quanto na sua quantidade e em ambas as dentições. Existem pelo menos catorze subtipos diferentes de amelogénese imperfeita, sendo as do tipo hipoplásico, hipomaturado, hipocalcificado e hipoplásico ou hipomaturado com taurodontia segundo o seu fenótipo e quinze subtipos, segundo o seu modo de transmissão. Segundo a literatura, os pacientes com amelogénese imperfeita, independentemente do subtipo presente, apresentam complicações orais semelhantes: estética dentária comprometida, sensibilidade dentária e diminuição da dimensão vertical de oclusão. O tratamento destes pacientes assume um papel relevante, na medida em que requer cuidados especiais, já que esta doença acarreta, por norma, problemas psicológicos e interfere com o autoestima do individuo. É notória, atualmente, uma oferta variada de opções reabilitadoras ao dispor do Médico Dentista, que ajudarão o mesmo a restabelecer a estética e função. Os tratamentos são variados e por vezes complexos, podem ser desenvolvidos de forma conservadora ou invasiva. Contudo, a escolha do melhor tratamento será consequência da gravidade da patologia e de fatores inerentes ao próprio paciente. Neste estudo, abordamos as facetas, como uma alternativa reabilitadora, que com o avanço e melhorias na área da Dentisteria Estética, nomeadamente no que diz respeito à adesão à dentina, parecem ser uma opção credível. Assim, o objetivo desta dissertação é demonstrar e elucidar a reabilitação dos defeitos associados a esta doença com a utilização de facetas diretas e indiretas. Foram efetuadas pesquisas e consulta de livros, monografias, dissertações, artigos em base de dados como o Pubmed/Medline, para que conseguíssemos realizar uma discussão sobre o mesmo tema e desta forma encontrar uma adequada resposta a todas as nossas inquietações sobre esta questão.

Optimizing maxillary aesthetics of a severe compromised tooth through orthodontic movement and dental implants

Treatment of severe compromised tooth in the maxillary anterior area still poses great challenge to the clinicians. Several treatment modalities have been proposed to restore the function and aesthetics in teeth with advanced periodontal disease. The present study aims to report a case of traumatic injury of a left-maxillary central incisor with ridge preservation, orthodontic movement, and implant therapy. A 45-year-old woman underwent the proposed treatment for her left central incisor: basic periodontal therapy, xenogenous bone graft, and guided bone regeneration (GBR). Six months after the graft procedure, orthodontic movement by means of alignment and leveling was made and a coronal displacement of the gingival margin and vertical bone apposition could be observed after 13 months of active movement. Afterwards, a dental implant was placed followed by a connective tissue graft and immediate provisionalization of the crown. In conclusion, orthodontic movement was effective to improve the gingival tissue and alveolar bone prior to implant placement favoring the aesthetic results. Six years postoperatively, the results revealed height and width alveolar bone gain indicating that the treatment proposed was able to restore all the functional and aesthetic parameters.

Factors to Achieve Aesthetics in All-Ceramic Restorations

The demand for aesthetic restorations has increased during the last years. Dental ceramics are a successful alternative for some cases because of aesthetics and biocompatibility. Therefore, the aim of this literature review was to present the factors necessary to fabricate all-ceramic restorations with aesthetics similar to natural dentition. A search of English-language peer-review literature was completed using MEDLINE database from 1975 to 2009 including the keywords "aesthetic," "metal-free crown," "all-ceramic," and "color." It was observed that several factors influence aesthetics of all-ceramic restorations. Color scale, light source during color evaluation, characteristic of core material, color of supporting tooth, presence of root post, and type of cement are clinical factors that may influence color of the restorations. Laboratorial factors as technique for ceramic condensation, thickness, temperature, and number of firing cycles also influence the result of these crowns. Although several clinical and laboratorial factors influence aesthetics of all-ceramic restorations, the aesthetic success and longevity of these restorations depend on the integration with surrounding periodontal tissue.
