A comparative study between the immediate and early implant on the aesthetic influences of the peri-implant soft tissues in the aesthetic area / 口腔疾病防治

Objective@# The aim was to compare and document the aesthetic influences on peri-implant soft tissues between the immediate and early implant placement in the aesthetic area. @*Methods @#22 patients with single anterior teeth missing were included and divided into 2 group. Group A (12cases): Following the extraction of teeth, 12 Zimmer implants were immediately placed into sockets. Group B (10 cases): 4~8 weeks after the extraction, 10 Zimmer implants were early placed into the healing sockets. Zirconia crowns were applied on the implants 6 months later after implantation. The peri-implant soft tissues in both group were examined and evaluated by pink esthetic score (PES) 6~12 months later. Analysis of the data was performed by software SPSS 13.0. @*Results @#The mean PES was 9.27 (clinical acceptance) for all of the implants. No significant were found for any of the parameters between the treatment modalities regardness of total PES or single PES. However there were significant differences in the following aspects: the correlation between periodontal disease and papilla, the correlation between gingival biotype and mesial papilla, the correlation between gingival biotype and alveolar process deficiency, the correlation between Implant location and midfacial soft tissue level. @*Conclusion@#There are no significant differences between immediate placement and early placement on the aesthetic outcome of peri-implant soft tissues. The aesthetic outcome are related to patients oral health condition and clinicians skills.

The immediate implant and delayed restoration in maxillary esthetic zone: A case report and literature review / 口腔疾病防治

Objective@#To investigate the effects of the related factors on the aesthetic implant restoration of anterior maxilla with a typical case report. @*Methods @#A patient, who was failed with metal-ceramic bridge half year, required an implant restoration. Before treatment, a thorough clinical and radiological examination and a SAC classification were done. The teeth were extracted in mininal truama without flap reflection, and implants were inserted with delayed restoration. A provisional restoration supported by temporary abutment was placed to guide the development of the soft tissues. Then the final impression with the custom-made transcopings was made. And a screwretention metal-resin bridge was made with CAD/CAM titanium framework.@*Results@#During follow-up the dental implants and provisional restoration provided the patient with good esthetics, pronunciation and chewing function.@*Conclusion@# Many factors may affect the success rates and asethetic effect of anterior implant restorations. Indications, pre-surgical assessments, treatments are keys to aesthetic implant restoration.

Esthetic restoration in continuous maxillary anterior area using immediate implant placement: A case report / 대한치과보철학회지

In the case of an extraction in the maxillary anterior region, immediate placement of implant-supported fixed prosthesis can be considered as a treatment option. Fewer surgical operations, reduced treatment time, and optimal availability of existing bone are obvious advantages of the method; however, when applied in the continuous maxillary anterior region, inter-implant distance must be carefully considered, as well as accurate diagnosis and treatment planning for predictable outcome. In this case report, immediate placement of two implants in the continuous maxillary anterior along with bone graft following the extraction of root rests, and the restoration of provisional and implant-supported fixed prosthesis on a 63-year-old patient had resulted in both esthetically and functionally satisfactory clinical outcomes.

Reabilitação imediata com implantes dentários em paciente periodontal / Immediate implant placement and provisionalization in the periodontal patient - A clinical report

A colocação de implantes dentários em alvéolos frescos de pacientes periodontais é questão de debate, assim como a colocação de provisório imediato em função. Este trabalho teve como objetivo demonstrar a instalação de implantes dentários em alvéolos frescos, após a exodontia de dentes anteriores periodontalmente comprometidos, a reabilitação provisória imediata e o restabelecimento da estética pela prótese fixa com gengiva de cerâmica. De acordo com os resultados obtidos, pudemos concluir que, na região anterior da maxila, os implantes dentários em alvéolos frescos com restauração imediata podem ser realizados com sucesso em pacientes periodontais, de acordo com protocolos cirúrgico e protético adequados.

Placement of dental implants in fresh extraction sockets of periodontal patients is a controversial issue, as well as its immediate functional restoration. This article aims to demonstrate the placement of dental implants in fresh sockets after extraction of anterior compromised teeth, with immediate provisional restoration, and the reestablishment of aesthetics by fixed prosthesis with pink porcelain. According to the results, one can conclude that in the anterior maxillary region, dental implants in fresh extraction sockets of periodontally compromised patients can be placed in immediate function whenever appropriate surgical and prosthetic protocols are observed

Immediate placement and loading of implants in anterior maxilla using an altered screw-retained implant fixed prosthesis.

This article describes the immediate placement and loading of implants in the aesthetic zone using an implant-retained, fixed prosthesis with a modified design. One section of the implant prosthesis has cemented crowns and the other section is the conventional screw-retained. This combined approach significantly offsets the unsuitable implant position, alignment or angulation, while ensuring the easy retrievability, repair and maintenance of the prosthesis at the same time.

The influence of magnet on tissue healing after immediate implantation in fresh extraction sites in dogs / 대한치과보철학회지

STATEMENT OF PROBLEM: The clinical use of electric and electomagnetic fields for fracture healing applications began in the early 1970s. Since then, several technologies have been developed and shown to promote healing of fractures. Developments of these devices have been aided in recent years by basic research and several well controlled clinical trials not only in the medical field but in dentistry. PURPOSE: The purpose of this study was to compare alveolar bone reduction following immediate implantation using implants onto which magnets were attached in fresh extracted sockets. MATERIAL AND METHODS: Four mongrel dogs were involved. Full buccal and lingual mucoperiosteal flaps were elevated and third and fourth premolars of the mandible were removed. Implants with magnets and implants without magnets were installed in the fresh extracted sockets and after 3 months of healing the animals were sacrificed. The mandibles were dissected and each implant sites were sampled and processed for histological examination. RESULTS: The marginal gaps that were present between the implant and walls of the sockets at the implantation stage disappeared in both groups as a result of bone fill and resorption of the bone crest. The buccal bone crests were located apical of its lingual counterparts. At the 12 week interval the mean of marginal bone resorption in the control group was significantly higher than that of the magnet group. The majority of specimens in magnet group presented early bone formation and less resorption of the buccal marginal bone compared to the control group. CONCLUSION: Within the limitations of this study, it could be concluded that implants with magnets attached in the early stages of implantation may provide more favorable conditions for early bone formation and reduce resorption and remodeling of marginal bone.
