RESUMEN

OBJECTIVE: The aim of this study was to test a new portable vibrator for plaster pouring (developed for this purpose), comparing the effect of its use on the accuracy of working cast of implant-supported restorations to the conventional vibrator. MATERIAL AND METHODS: From a master cast with 2 implants, 30 transfer moldings were made randomly and divided into three groups: Group I (GI): pouring performed in an outsourced dental laboratory with conventional plaster vibrator (10 casts), Group II (GII): pouring performed in the laboratory of the Federal University of Santa Catarina (UFSC) with conventional plaster vibrator (10 casts) and Group III (GIII): pouring performed with the portable vibrator fabricated for this study (10 casts). The position of the analogue and marginal adaptation of the infrastructure were verified by testing the single screw on the master model and on the working model. The measurement of misfit was blindly performed with a precision microscope and analyzing unit, Quadra-Check 200. The data were statistically analyzed by analysis of variance (ANOVA) and the Holm-Sidak test (α=0.05). RESULTS: Means±standard deviations were as follows: GI: 19.19±4.73 µm; GII: 21.72±5.41 µm; GIII: 13.5±2.39 µm (P<0.05), with GIII significantly lower as compared to the other groups. CONCLUSION: Within the limitations of this study, it was concluded that a greater accuracy of working cast was achieved when a portable vibrator was used for casting molds.

RESUMEN

A utilização de implantes curtos (6,0–8,5mm) no tratamento reabilitador vem sendo bastante empregada em locais onde a altura óssea é limitada ou em regiões próximas a estruturas anatômicas importantes. Historicamente, o uso de implantes curtos tem sido associado a menores taxas de sucesso quando comparados com implantes de comprimento convencional. Entretanto, estudos clínicos recentes mostram uma similaridade na taxa de sucesso de implantes curtos e convencionais. Tanto para o clínico quanto para o paciente, esse tratamento apresenta-se como uma alternativa simples e segura, devido à redução dos custos, procedimentos cirúrgicos, morbidade e tempo de tratamento. Devido à similaridade nas taxas de sucesso, a indicação de implantes curtos pode ser feita em praticamente todos os casos, assim substituindo a realização de procedimentos invasivos para reconstrução do volume ósseo. O presente artigo apresenta uma resolução clínica que mostra a utilização de implantes curtos em mandíbula e maxila.


Short dental implants (6.0-8.5 mm) have been widely used in the rehabilitation of atrophic areas or in sites close to important anatomic structures. Historically, short implants were associated with lower success rates when compared with the treatment using long implants (>8.5 mm). However, recent clinical researches show similar success rates to short and long implants. Moreover, this sort of treatment is considered a simple and safe option for both patients and surgeons. It has the potential of decreasing costs, number of surgical interventions, treatment time and morbidity. Due to the similarity between both types of implants, short implants have been largely used as a substitute for invasive surgical interventions for bone volume reconstruction. This paper shows short dental implants as a safe clinical option for the rehabilitation of atrophic maxilla and mandible.
