ABSTRACT
Quando bem indicado, o implante imediato com carga é uma opção segura e eficiente para substituição de elementos dentais unitários condenados, com previsibilidade e altas taxas de sucesso quando se buscam fatores como conforto, estética, função e fonética. Uma técnica atraumática, aliada à habilidade do operador, e um bom remanescente ósseo são fatores determinantes no sucesso do tratamento. O objetivo desse trabalho foi apresentar um caso clínico de instalação de implante imediato em região anterossuperior com carga imediata, provisionamento com dente decíduo e prótese definitiva livre de metal, com acompanhamento de quatro anos.
When properly indicated, the immediate dental implant with loading is a safe and efficient option with predictability and high success rates for patients in need of comfort, esthetics, function, and phonetics. An atraumatic technique allied to the operator's skill and a good bone site are mandatory to the treatment success. This case reports the 4-year follow-up on the use of an immediate implant/loading procedure after extracting a maxillary deciduous lateral incisor and delivery of a metal-free restoration.

PURPOSE: The purpose of this study was to compare marginal bone loss and success rates 1 year after implants had been placed in maxillary molar sites, either immediately postextraction or after the extraction sites had healed (delayed). MATERIALS AND METHODS: A retrospective case study was made of subjects treated with immediate or delayed dental implants in the maxillary molar region between January 2006 and December 2008. A protocol was prepared in which patient age, sex, implant length and diameter, type of prosthesis, buccal plate width, and use of bone grafting were recorded. After 12 months, data relating to the clinical and radiologic conditions of the implants and the success rate according to the criteria of Buser et al were recorded. The variables were analyzed statistically (Student t test, Pearson correlation, Games-Howell test). RESULTS: The study included 123 implants placed in 70 patients; 35 implants were immediate and 88 were delayed. Two immediate and six delayed implants failed, resulting in success rates of 94.3% and 93.2%, respectively. Average marginal bone loss was 0.56 mm for immediate implants and 0.67 mm for delayed implants. CONCLUSIONS: The placement of immediate implants in maxillary molar sites achieved similar results to implants placed in healed sites in the same region after 12 months. No statistically significant differences were found between implant survival rates or average marginal bone loss.

PURPOSE: To compare the success rates, after 1 year of loading, for implants placed immediately after tooth extraction and in healed sites in patients undergoing extraction of all residual teeth for rehabilitation with a fixed, full-arch, implant-supported prosthesis. MATERIALS AND METHODS: A retrospective case series study was conducted of 38 patients treated from June 2004 to June 2008 by extraction of all remaining teeth and implant placement in both mature bone and at the extraction site in the same procedure. After osteointegration, the implants were restored with fixed full-arch prostheses. The marginal bone loss around the implants was measured after 1 year. The success rate according to Buser criteria was calculated for the immediate and nonimmediate implants. RESULTS: A total of 41 arches were restored in 30 patients, 23 in the maxilla and 18 in the mandible. A total of 292 implants were placed, 173 immediately and 119 in mature bone. Of the 292 implants, 8 failed, 4 in the immediate group and 4 in the nonimmediate group. The mean bone loss was 0.6 mm at 1 year of loading (0.63 ± 0.18 mm at the immediate implant sites and 0.58 ± 0.26 in mature bone). The mean success rate was 96.9% overall, 97.7% for the immediate group, and 96.3% for the nonimmediate group. CONCLUSIONS: Enhanced bone healing and remodeling can take place in fresh extraction socket defects associated with immediately placed implants. The results of the present study have demonstrated that immediate implant osseointegration can be as, or more, successful than nonimmediate implantation during the same healing period.
