Avaliação do impacto do número de implantes empregados para reabilitação tipo protocolo sobre a qualidade de vida, satisfação do paciente e sobre o sucesso dos implantes e da prótese instalados

Abstract

Rehabilitation of edentulous arches with implant-supported full-arch fixed protheses is a settled treatment, however simplification of this treatment is sought in order to reduce the costs and trauma to the patient. Studies have evaluated the survival of dental implants when they are used in reduced number, nevertheless the focus should also be on maintaining the prostheses and the patient’s own perception of their treatment. Thus, this thesis aimed to assess the impact of the number of implants used to support full-arch fixed prostheses upon quality of life, patient satisfaction and the success of installed implants and prostheses. This work was divided in three specific objectives. Objective 1: Impact of Implant Number on Mandibular Implant-Supported Profile Prostheses: A Systematic Review. To review whether the number of implants used to support a mandibular profile prosthesis does influence the implant survival rate, marginal bone loss and prosthesis survival rate. Objective 2: Number of implants used in full fixed implant supported prostheses in maxilla: systematic review. To evaluate if the number of implants used in full fixed implant supported prostheses in maxilla does influence the implant survival rate, marginal bone loss and prosthesis survival rate. Objective 3: Maxillary Implant supported full-arch rehabilitation using different number of implants: three cases report. To report three cases of patients rehabilitated with Implant supported full-arch fixed prostheses, using different number of implants, and discussed the impact of this rehabilitation on quality of life and patient’s satisfaction. After the data analysis, the authors concluded that: mandibular profile prosthesis supported by three implants showed satisfactory implant survival rate and marginal bone loss in the first year, however the prosthesis survival rate was inferior to other groups and this suggests a longer follow-up for these rehabilitations; the implant and prosthesis survival rate, as the marginal bone loss of full-arch fixed prostheses supported by four implants were satisfactory compared to different number of implants. Concerning to the oral health quality of life impact and patient’s satisfaction, the presented cases showed satisfactory scores, regardless the number of implants installed.
