ABSTRACT

RESUMEN: La situación de gran competitividad profesional que estamos experimentando actualmente exige la necesidad de una demanda formativa cada vez mayor, que deriva en la "superespecialización" de los odontólogos/ estomatólogos. Por ello, la asociación entre diversos "especialistas" cada vez es más común con el fin de proporcionar al paciente un tratamiento global y de calidad dirigido a satisfacer sus necesidades asistenciales. El objetivo del presente artículo es presentar el tratamiento multidisciplinar, de un paciente con una transposición del canino definitivo con el incisivo lateral derecho temporal, y su rehabilitación con un implante osteointegrado.


ABSTRACT: Dentistry nowadays is a very competitive field; that is why the amount of professionals that look for an academic training on specific topics is increasing. The importance of permanent communication with other professionals during the planning stage is the key for a successful treatment. The objective of this clinical case is to present a multidisciplinary work, focused on dental rehabilitation of a patient with an agenesis of the permanent right incisor in the maxillary bone and its treatment.

ABSTRACT

PURPOSE: The purpose of this randomized clinical trial is to determine whether implant length and the crown-to-implant (C/I) ratio influence implant stability and peri-implant marginal bone loss (MBL). MATERIALS AND METHODS: 46 patients with single tooth missing in the posterior molar region of the mandible were included in this study. 19 implants (CMI IS-III active® long implant) of 5.0 mm diameter and 10 mm length were installed for the control group, while 27 implants (CMI IS-III active® short implant) of 5.5 mm diameter and 6.6, 7.3 or 8.5 mm length were placed for the experimental group. Each implant was inserted and immediately loaded using the digitally pre-fabricated surgical template and provisional restoration. The CAD-CAM monolithic zirconia crown was fabricated at 3 months after the surgery as a definitive restoration. The ISQ value and the MBL was measured at 48 weeks after the surgery. The correlation between the C/I ratio, MBL, and secondary implant stability was analyzed. RESULTS: Successful results in terms of ISQ and MBL were achieved with both groups. There was no significant difference between the groups in terms of ISQ values and MBL at 48 weeks after the surgery (P > 0.05). No significant correlation was found between the C/I ratio and secondary stability as well as the C/I ratio and the MBL (P > 0.05). CONCLUSION: The influence of C/I ratio in both groups was not shown on the stability nor the marginal bone loss in implants supporting single crown of the mandible. Short implant could be a preferable alternative option in the reduced bone height mandible under the limited condition despite its higher C/I ratio.

ABSTRACT

Lack of standard criteria in the outcome assessment makes it difficult to draw conclusions on the clinical performance of short implants and, under these circumstances, determine the reasons for implant failure. This study evaluated, through a systematic review of the literature and meta-analysis, the essential parameters required to assess the long-term clinical performance of short and extra-short implants. Electronic databases (Pubmed-MEDLINE, Cochrane Library Database, Embase, and Lilacs) were searched by two independent reviewers, without language limitation, to identify eligible papers. References from the selected articles were also reviewed. The review included clinical trials involving short dental implants placed in humans, published between January 2000 and March 2014, which described the parameters applied for outcome's measurements and provided data on survival rates. Thirteen methodologically acceptable studies were selected and 24 parameters were identified. The most frequent parameters assessed were the marginal bone loss and the cumulative implant survival rate, followed by implant failure rate and biological complications such as bleeding on probing and probing pocket depths. Only cumulative implant survival rate data allows meta-analysis revealing a positive effect size (from 0.052 (fixed) to 0.042 (random)), which means that short implant appears to be a successful treatment option. Mechanical complications and crown-to-implant (C/I) ratio measurement were also commonly described, however, considering the available evidence; no strong conclusions could be drawn since different methods were used to assess each parameter. By means of this literature review, a standard evaluation scheme is proposed, being helpful to regiment further investigations and comparisons on future studies.

A falta de critérios padronizados para a avaliação dos resultados faz com que seja difícil tirar conclusões sobre o desempenho clínico dos implantes curtos e, nestas circunstâncias, determinar as razões para o fracasso do implante. Este estudo avaliou, através de uma revisão sistemática da literatura, os parâmetros essenciais necessários para avaliar o desempenho clínico em longo prazo de implantes curtos e extra-curtos. Bases de dados eletrônicas (PubMed-MEDLINE, Base de dados da Biblioteca Cochrane, Embase e Lilacs) foram avaliadas por dois revisores independentes, sem limitação da linguagem, de modo a identificar artigos elegíveis. As referências dos artigos selecionados foram também analisadas. A revisão incluiu estudos clínicos, publicados entre janeiro de 2000 e março de 2014, envolvendo implantes dentais curtos, instalados em seres humanos, nos quais foram descritos os parâmetros utilizados para mensuração dos resultados e fornecidos dados sobre as taxas de sobrevivência. Treze estudos metodologicamente aceitáveis foram selecionados, sendo identificados 24 parâmetros. Os parâmetros avaliados com maior frequencia foram a perda óssea marginal e a taxa cumulativa de sobrevivência do implante, seguida pela taxa de falha dos implantes e complicações biológicas, tais como sangramento à sondagem e profundidade de sondagem. Apenas a taxa cumulativa de sobrevivência dos implantes permitiu a meta-análise revelando efeito positivo (variação de 0.052 (efeito fixo) até 0.042 (efeito aleatório)), demonstrando que os implantes curtos parecem ser uma opção de tratamento bem sucedida. Complicações mecânicas e a mensuração da proporção coroa-implante foram também referidas, entretanto, considerando-se as evidências disponíveis, não se pode chegar a fortes conclusões, pois diferentes métodos foram utilizados para avaliar cada parâmetro. Por meio desta revisão da literatura, um esquema padronizado de avaliação é proposto, sendo útil para arregimentar ...

ABSTRACT

O objetivo deste estudo retrospectivo foi avaliar o índice de sobrevivência dos implantes curtos em diferentes situações clínicas, com um acompanhamento clínico mínimo de 12 meses. Material e Métodos: no período de setembro de 2005 a dezembro de 2011, implantes curtos (8,5 mm ou inferior) foram instalados em pacientes da clínica dos autores e da clínica da Unifeso, para substituir dentes unitários e múltiplos nas regiões anterior e posterior da maxila e da mandíbula. Todas as áreas implantadas apresentavam uma elevada reabsorção óssea. Resultados: um total de 335 implantes foi instalado, em 107 pacientes (69 mulheres e 38 homens) com idade média de 68 anos (54 a 82 anos). Os implantes instalados foram 54,6% com o comprimento de 6 mm, 40,3% com comprimento de 8,5 mm e 5,1% com comprimento de 7 mm, distribuídos na região anterior (10,4%) e região posterior (89,6%) da maxila e da mandíbula. Foram utilizadas coroas individuais em dez implantes (3,2%), e 299 implantes foram reabilitados com próteses múltiplas parciais e totais (96,8%). Dentre os 299 implantes, 13 (4,2%) foram submetidos à carga imediata. Após um acompanhamento de um a cinco anos, 309 implantes apresentavam-se em função e 26 implantes foram perdidos, atingindo um índice de sobrevivência de 92,2%. Conclusão: os resultados do presente estudo sugeriram que os implantes curtos apresentaram um bom índice de sobrevivência, devendo ser considerados como uma solução previsível para a reabilitação da maxila e da mandíbula, com elevado grau de reabsorção...


The aim of this clinical retrospective study was to assess the survival rate of short implants in different clinical situations with a minimum 12-month follow-up period. Materials and Methods: between September 2005 to December 2011, short dental implants (8.5 mm or shorter) were placed in patients of authors and Unifeso clinics to restore single and multiple teeth in the anterior and posterior jaw regions. All areas were affected by high bone resorption patterns. Results: a total of 335 implants were placed in 107 patients (69 women and 38 men) with a mean age of 68 years (range: 54–82 years). The implants placed were 6 mm (54.6%), 7 mm (5.1%), and 8.5 mm (40.3%) long, distributed in the anterior (10.4%) and posterior (89.6%) regions. Single crowns were placed in 10 implants (3.2%), and 299 implants received multiple partial and complete prostheses (96.8%). From these, 13 implants (4.2%) were submitted to immediate loading. After 1-5 year follow-up period, 309 implants are in function and 26 implants have been lost, achieving a survival rate of 92.2%. Conclusion: the results of this study suggested that short dental implants presented a good survival rate and therefore should be regarded as a predictable solution for the rehabilitation of highly resorbed jaw regions...
